Thank you. During the 1960's, high school and college coaches were telling athletes not to drink water after intensive exercise in the heat!! Crazy.

[@DemstarAus]

What reasoning did they use?

[@HiddenWindshield]

@@DemstarAus They thought it would make you sick.

[@user-vd8nm8sv6x]

@@HiddenWindshield I mean? That CAN be true, but it’s not common. And jesus, no water at all? Most of the time you only get sick if you: drink a lot of water extremely fast; almost immediately afterwords, you begin vigorous exertion; you don’t do any proper warm ups; you don’t take any breaks; etc! But then again, it was the 60s, health and fitness back then was… interesting. lol

[@HiddenWindshield]

@@user-vd8nm8sv6x Yeah, that was the myth. You should read up on the invention of Gatorade; they weighed athletes before, during, and after a sporting event, and IIRC they were losing 10-15 lbs (5-9 kg) in water weight over only a few hours.

[@jackcough8155]

yeah who needs water? just drink vodka n smoke meth

[@jiayuzhang9681]

Hi Chybbyemy, I first saw your “How I lost 60 pounds in 16 weeks” video back in 2016. Over the years, I’ve been randomly checking back until this spring break during COVID I stumbled upon your “Life” playlist and it really changed how I look at things. Back in grades 8, 9 and 10, I was a loser who only played Video games and napped after school. I was that kid who never did any work and well, got what I deserved. I was averaging less than 60%. What was more humiliating for my parents was that well, I’m ASIAN. I bet you know the stereotypes for Asians being smart and good at math. Well, I'm busting that myth right here for anyone else who reads this. IT'S NOT TRUE. No one can get 100% on a test just because they are a certain race or ethnicity. We are all humans after all. Anyways, grade 11 comes around. I got my shi* together and I guess did an ok job in grade 11 averaging in the high 80s, low 90s. I’m turning grade 12 in September. I hope I can better myself again. Your medical videos sparked my interest in medicine. your fat loss videos inspired me to get off my butt and exercise a whole lot more. Most importantly, your life videos made me realized what I needed to do. I hope I can follow your paths regardless of the hardships. Because discipline is the key to success. Have a nice day or night whoever is reading this!

[@RainbowFlowerCrow]

You've got this, kid! Good on you for your positive attitude and determination!

[@justanotheryoutubeaccount2270]

Great! I think you're going to thank yourself in the future for that.

[@Ennello]

I had the same problem. I'm not used to working a lot to get good results. In high school I was getting grades of 90% and more with little to no work. That's why I now find myself in a situation where I have no discipline whatsoever. Now I'm studying medicine and I'm having trouble doing the work I need to do to get the grades I could get. I still pass every time, but I'm not at all happy with the work I put in, and in the long term, it will show that I haven't put the work in that other people have. I've only recently backed away from gaming and watching series a bit and I'm a lot happier with myself. I can finally see that the results I get are the result of the work I do, and not of one of those tiny last-minute efforts I used to make. It makes me happy to see your comment! I hope you keep your motivation up! I will try my best to do the same.

[@mschuhler]

i remember last time i got it, i took an ice bath at home and it didn't even feel particularly cold

[@shaylatwitchell2567]

I can relate. Heat sensitivity runs in my family and I have it too, so by default I'm more prone to get heatstroke even in slightly-cooler weather. I live in Arizona.... It's uhhh fun trying to make sure i don't get heatsick

[@SheikhN-bible-syndrome]

Yeah I was born with a week heart and I get over heated real easy

[@kimberlypatton205]

As a retired horticulturist, I learned a long time ago to learn about my own body’s heat response. I worked most days outdoors, in the constant West Texas Summer heat of 95 degree + days. Also being physically active at the same time. Being a highly healthy person, I paid attention to how my face looked… my face became VERY flushed at a critical heat point for myself. I knew then was the time to down an electrolyte drink, wet myself ( my head especially!) with cool water from the hose and sir it out in the shade a while. Heatstroke is no joke, and the delirium it can cause may impair your mental ability which can be fatal. Learn to address any symptoms early and take care of yourself!

[@SpudBySea]

Another great video- especially appreciate the direct comments on bad coaching believing more sweat is better. It might be due to editing, but the asthma study commentary at 9:40 doesn't fit the narrative well. It seems introduced to suggest that since a totally different topic on life expectancy has contradictory evidence that no beliefs on life expectancy impact are certain. It doesn't really jive with the thorough and data-driven tone of HR.

[@HemeReview]

thanks. the point was that calculating mortality risk when looking retrospectively can have many problems. i cut out additional commentary in that line, maybe ill revisit it in another episode

[@incredibleedibledez]

I loved this so much!! I've had multiple sclerosis for over 10 years & my symptoms get worse when I get hot but I never understood(or could get an answer why) until I saw your explanation about interferons in this episode!!

In short: Got a heat stroke and covid on a cold day somehow

[@taleandclawrock2606]

I have Hashimotos, which in the literature states one consequence is reduced regulation of electrolyte -water balance in body. Since i developed it 8 years ago, i sweat profusely, just froma warm day or high humidity or ordinary housework. Its embarassing socially, and i frequently feel nauseous, bad headaches and loss of motor skills- increased clumsiness. I have tried to manage this as best i can, but have had so little recognition, advice or support from Australian doctors to manage it. It is literally disabling, and i can only endure part time work, as my health goes into a downward spiral otherwise.

[@isaiahschmitt8680]

Your doctors must be incompetents, Hashimoto's isn't very hard to treat, you can usually just give the patient levothyroxine, and an adequate dose of levothyroxine should prevent all of the symptoms of hypothyroidism you have.

[@ersetzbar.]

I always assumed the human body is well researched, but having it explained into such detail for an example is still mind blowing. Finding out the body functions that are connected from this huge complicated chemical system, filtering those unrelated and sorting for cause and effect must be so very difficult.

As a one of those i was so grateful that you provided your first channel videos with ENG SUB, but you speak SO well that autogenerated subs on this channel are higly coherent so i get every single professional (or not) word very clearly (now that i learned exactly what does -emia and stuff mean from chubbyemu).

THANK YOU doc from the eastern europe country everyone constantly makes fun of :))))

This happened to me once and was terrifying. I was so confused I didn’t even know my name. I was outside painting the side of the house and fainted. My partner was inside and had no idea. We had just moved into this new neighborhood so I didn’t know where I was and was walking around the neighborhood in painting clothes and looked like a crazy homeless person. I was hiding in bushes and blacked out while walking around. By some miracle, I found my way back to the house in tears with a splitting headache. I just put cold compresses on my head to cool down. It took me two days to recover. The only thing I could think is this is what it must feel like when people have dementia. 😔😢 (Florida)

Hey Bernard, another great video from you. I usually enjoy learning about medicine, but the way you present these cases makes it even more enjoyable for me. That being said, I do have a brief thought after watching this video. I believe that learning how to recognize and treat heat stroke is only going to become more and more important for doctors and nurses, especially with the Earth continuing to warm, and heat waves becoming more and more frequent.

I had heatstoke almost every summer as I forget to bring water or too broke to get a bottle at a store or no fast food won’t give me one free cup of water or i have to pay 1.00 here in Alberta Edmonton’s McDonald’s. It’s not fun at all imagine your up but you know you feel off and fuzzy very warm, them weakness sets in and then blackout... i always wake up in a bed or a bench when someone is phoning 911 and keeping me cooled till they show up. Also I don’t sweat at all since birth and i got no Diabetes

You never forget the water! I keep water in the fridge like a religion in summer and I have two water bottle carrier slings so I can bring water even if I bring nothing else. If I am planning to go for a walk longer than to the corner I set it out so I see it before I leave no matter the weather.

[@luvondarox]

I got heatsick as a kid during our school's Field Fun Day when it was around 100°F, the teachers / chaperones didn't permit water breaks except at lunch, and it wiped me out for a good week or so. Ever since then I've been infuriatingly sensitive to heat, and working outside in humid 90° - 100° weather gives me a headache no matter how much water I drink. If I persist my brain gives me a final ultimatum of Pounding Skull before holding me hostage with a raging migraine that takes days to recover.

[@spvillano]

I had a heat stroke while in the Persian Gulf region in 2009. Broken AC in the car (no air conditioned showrooms at the repair shop, so I figured I'd wait for it to cool down before getting it fixed), dehydrated slightly secondary to having a few drinks the evening before, got stuck in traffic on the way to the base and I had for once, forgotten to bring a few bottles of water to work with me. Got to the base and was already beginning to experience a heat stroke. Base security delays in the sun made it a bit worse. I managed to get plenty of water into me at the MP station, as initially everyone thought I was inebriated and as I downed my 6th bottle of water, it dawned on the MP's what was actually going on. I recovered, minor cardiac damage with a slightly funky QT interval and sent the ECG analyzer into fits claiming digitalis effect, throw PVC's moderately often after and throw a bit of protein in the urine. Amazingly, my liver didn't show any damage whatsoever!

[@emerald4812]

I had a minor heatstroke last year. It was the first really hot day of the year, so we went to the beach. I forgot to drink water and laid out in the sun for a few hours. I felt sweaty, nauseous and I actually fainted. Luckily after some time in a cool, ventilated place I felt a bit better. To be honest it really sucked. I do faint fast, my blood pressure is naturally low, but this faint felt worse than the others. Be safe, and seek shade on the beach in hot weather!

[@billymanilli]

I experienced exertional (sp?) heatstroke around 10 yrs ago.... Working in the middle of summer in my driveway trying to finish putting struts in the front of one of my customer's Cadillacs... NOT to be messed around with. It was freaking scary

[@nerysghemor5781]

....and I almost ended up presenting to the emergency room last year due to heat exhaustion. Actually experiencing it for myself was really crazy. Fortunately I made it to shade, AC, and water, before I had any damage. The fever in my case never went above 102, which was enough to feel something was very wrong, but I did manage to get my temp down in time. I did an incredibly stupid thing by walking a mile and back to a store on a day that was 100+ outside because my car was in the shop and I wanted out of the house that bad. I would have deserved the infamy of a Chubbyemu video after that if I really HAD had to call for an ambulance instead of managing to get back to my house.

[@arthurfelipemuckenheim851]

I went through a very similar situation a few years ago. There was a nasty heat wave going on and I had to walk about 15 minutes to the shop in 104°F or 40°C (weather app said it felt like 120°F/49°C) just to see when I would get my car back (they weren't too big on answering the phone). The minute I stepped into the air-conditioned office I felt light headed and my fingers started tingling and I thought I was gonna pass out. Thankfully the shop owner gave me a ride back home afterwards. Fun times those weren't.

[@erictaylor5462]

When I was a teenager I was working at a small store. It had been very hot over the two previous weeks with temperatures over 100 degrees every day. We were selling tons of ice cream and I was sent into the walk in freezer to get more ice cream. The freezer was very old and it was not up to the level of safety it should have been and I ended up locked in the freezer. Keep in mind it was over 100 degrees and I was wearing only shoes and socks, shorts and a t-shirt. I had only planned on being in the freezer for a few seconds so I hadn't bothered with a jacket. My idiot boss was a drunk and never wondered where I went (I think he forgot he had sent me to get ice cream) so I was locked in the freezer for over an hour. Someone finally came into the freezer to get the ice cream I had been sent to get and found me unconcise on the floor of the freezer. They took me out of the freezer (which turned out to be the wrong thing to do) and called 911. Once at the hospital the paramedics had to teller the doctors twice that I had hypothermia not hyperthermia because it was so hot out, the doctors didn't think it was possible that I was too cold. In any case they gave me the correct treatment and I was in the hospital a few days. My boss got a huge fine but I never went back to work there. A few years later my boss drove the store into the ground and last I heard he's been killed in a DUI car accident, though I'm not sure it was true. It's kind of weird that I nearly froze to death on a day that was over 100 degrees. To this day I still can't stand being cold. It was one of the most unpleasant things I've ever gone through.

[@ulalaFrugilega]

Crass! Glad you made it!! Thanks for sharing.

[@lyravain6304]

I've lucklily never had to deal with heatstroke, but I have had fellow workers who have. As a background; I'm a cook. This means I regularly work in places that have terrible air flow, with open flames, heat-fans and deep-freezers. In one of the hotels I worked in, we had no air flow (air conditioners? fans? HAH, WORK SLAVE AND EARN ME MONEY, wish I was joking), two frying pans big enough they came with a winch, a pasta boiler that could fit a grown person, dozens of open flames, 4 deep fryers and 3 gas-operated ovens. All of which would often run at the same time, for HOURS. To shorten it up; if an egg broke on the metal countertop, IT WOULD COOK. Now stay in that room for 8-10 hours. Staying in that area, we never really realized how blisteringly hot it was. When the work flows and you have half-a-dozen foods to do, there's shouting, people getting in your way, customer complaints and having to supply two other kitchens... you lose track. You get accustomed to that heat. You ignore it with the same ease you ignore a tooth filling after an day. But that doesn't mean your body is okay; it just means you ignore the symptoms. We had fellow cooks who regularly had to be taken outside because they FAINTED MID-WORK. Personally; I contracted pneumonia. How? Well, after spending 5-6 hours in that heat, I'd often get asked (wrongly, but I'm a team-player and hard-worker so I don't mind helping my team) to retrieve whole lambs from the deep-freeze. Which, in that hotel, was at NEGATIVE 30 Celsius. Going from an air-temp of about 50-60 (if not more, but let's be conservative here), into negative-30 is a thermal SHOCK of 80-90 degrees. It didn't matter that I wore a coat; the moment I took a breath, all that ice would shred into my lungs. What I mean to say is; sometimes, heat and ice can sneak up on you. Be careful so you can be healthy. Take care of yourselves!

Quite a public service, Dr Bernard; thank you for putting so much into your channels!💪 -Emia means presence in blood!💖

[@rocketscientist1594]

The process of heatstroke sounds very much like the late stages of severe shock. I was reading up on shock after my husband died of septic shock, and what he was describing here - the damage to the microcirculation, the generalized ischemia, the gut leakage leading to endotoxemia, the disseminated intravascular coagulation, the resulting organ damage/organ failure - is exactly how shock kills. Very scary!

[@nighteule]

I've actually suffered what the paramedic called "heat syncope" before while on a trip to Louisiana. Not fun We were standing outside for a public event in the humid heat. My legs felt weak so I asked my mom if I could sit down. She said no, not understanding what was happening. My vision started to go dark. When it went black, I told my mom "I can't see". She thought I was joking, but by that point I was already starting to go down. That's the last thing I remember. When I began fading back into consciousness, I was in an air conditioned room with a bottle of Pedialyte in my hand.

[@vitorkiguchi4670]

6:44 not the specific heat, the latent heat. When we sweat we cool down due to the evaporation of the sweat, meaning what matters is the latent heat of the water. The specific heat doesn't really matter in this case, unless you're drinking cool water to replace the sweat (but then you'd achieve the same effect by urinating the water out instead)

I remember one day back in 2012-2013 or sometime around there. I and my father were out exercising, running in the woods. It was a really hot day, and I wore a black t-shirt, which didn't help with the heat as well. I started feeling really weak, like a super intense feeling of exhaustion. My dad thought I was just lazy, and I had no idea why I lost all of my energy but I started to feel like I would pass out. My dad ran home to get the car to pick me up, I was just laying on the side of the running track in the woods, in some shade trying to cool off. I felt really sleepy but I didn't want to sleep. I remember people walking past me, no one said a thing, which is pretty weird when I look back at it. I, just some dude laying on the side of the road in the woods, and no one cared to ask me what I was doing. Well, anyways my dad picked me up and we went home and drenched towels in cold water and put them over my head and back, I felt better after a few hours. I wonder if that could've ended in a heat stroke if I didn't pay much attention to how I felt. Good thing I wasn't alone.

[@SarahLovesBoobahandErEr]

I had heat stroke back in 2020. VERY scary. I was at work and my customers could tell something was not quite right with me. They gave me tea and water and I eventually sat in my car with the AC blasting. My body completely stopped producing sweat and I could tell I was feverish. My temp must have spiked up to 104+ because hours later, once I got home, my temperature had only dropped to 102. I suggest going to the ER! I should have!

I learned the expensive way that medical personnel are quick to overlook the dehydration and then syncope for a newly medicated high blood pressure victim. The drugs will dehydrate you! I drink lots of water, even electrolytes. I just should have been drinking even more water. By the time the ambulance got me to the ER the IV had replenished what I needed. That was when I should have refused admittance. Hind sight makes a know it all.

[@RoadkillbunnyUK]

My Grandfather died of heatstroke many, many years ago now, he was emigrating to Australia from England with his family (including my Dad who was a small boy at the time) back in the days when emigration to far off lands could only be done by ship (probably somewhere around 90 years ago). Half way into the voyage, probably in the vicinity of the Equator my Grandfather dies. He is buried at sea and on arrival to Australia my Grandmother and Father are forced to turn around and return my ocean liner back to the UK. My Dad was too young to really take all this in, his memory was very spotty around the whole thing, he probably was at most 5 years old. Sadly my Dad passed away 25 years ago from prostate cancer when I was just 16 so I never got to sit down with him as an adult and really talk about some of his amazing life experiences, like that fateful voyage or learning to fly planes in America in the Second World War eventually coming back to the UK and flying sea planes patrolling the Atlantic out of Northern Ireland. I still miss my Dad terribly and having a much older Dad means I have got quite a lot of sorries most 40 something don’t have!

[@NiceMuslimLady]

13:52 It's not JUST 3 litres of water you lose. It's also the electrolytes. It's something that I deal with...and people think I take in WAY too much salt...but, sometimes I have sodium deficiency. So...how do you handle that? MORE SALT! BTW...knowing that it's an issue, my electrolytes ARE monitored by a doctor.

[@xliquidflames]

I got it the day of "the great American solar eclipse" because my dad and I rode our Harleys up to South Carolina from Florida to get closer to the umbra. The morning of the eclipse, we found a little vacant parking lot and sat there all day waiting for it to happen. I was wearing my riding jacket, jeans, boots, gloves, helmet, ect. As the day went on we kept drinking plenty of water but I just kept getting hotter and hotter. The weather was zero clouds and the temp got around 95 that day. There was no shade to get under so I peeled off everything but my socks, jeans, and tshirt. But I couldn't get cool at that point. I knew I was in trouble when I stopped sweating and started getting chills and tingly all over and I was short of breath sitting down. They called an ambulance who pumped me with fluids and iced me down with ice packs. I was fine in about 15 mins. We got to see the eclipse. But it scared the hell out of me.

[@jessica5470]

Can I just say, from personal experience, do not use talc on places where you sweat, I didn't want to sweat at the gym one time so I put it all over, I had to leave after half an hour because my head was so hot

[@Ink_Tide]

I'm pretty sure I've gotten _close_ to exertional heatstroke but not quite there. I was biking uphill in very humid weather - the American Southeast has 90%+ humidity fairly regularly, and some people like to act like 'dry heat' isn't fundamentally different from humid heat for some reason despite the fact that the effectiveness of evaporational cooling (i.e. how sweat works) is essentially (100-X)% in X% humidity, meaning your body can cool itself, ideally, ~5 times more effectively in 50% humidity vs ideal cooling in 90% humidity, but I digress. When I hit the top of the hill I slowed down. This might have exacerbated things by stopping the breeze I was making, but within seconds of slowing I was hit with this intense wave of dizziness/nausea, and stopped. I felt an intense need to cool down, so I walked across the street into an air-conditioned building (it was part of the University I was at, so I didn't have to worry about it being locked). Thankfully, nobody was there to be bothered by me (or for me to be embarrassed about lol), because within moments of entering the building and heading downstairs towards the restroom, I just could not keep going and laid down on the stairs. My shirt was soaked and still hot, so I took it off while lying on my back and that gave some immediate relief. After probably a few minutes of just waiting to cool down, lying on some stairs with my shirt off and feeling my heartbeat in my ears, I was cool enough to finally reach the water fountain and restroom. I drank as much water as I thought I could and went into the restroom, and what followed was me in the restroom for something like 45 minutes while my digestive system emptied what felt like _all_ of its contents - including the water I just drank - into the toilet. I was on the toilet so long 'pooping' fluids I had enough time to look up what the hell was wrong with my body on the building's WIFI. Now I wasn't expecting a diagnosis, but it seemed like the public consensus was that since the epithelial cells of the intestines might be more sensitive to heat than most of the other cells in the body, me overheating had irritated my intestinal lining, and in my unprofessional personal experience my body's usual response to that sort of thing is "dump the system out through one end or the other." Overall it's an amusing story to recall, but somewhat sobering in terms of just how long it took to recover from overheating _despite_ the total time I had been outside being easily less than 5 minutes - I may have only actually been overheated for less than 30 seconds, and it still took literally an hour in an air conditioned building, most of which was spent wondering if my body would ever run out of stuff to dump into the toilet, to recover to the point where I felt comfortable going back outside. I'm not overweight. I'm fit and have years of experience running long distance _competitively,_ albeit at a high school level. I know what exhaustion feels like to my body, and this was something else entirely. If I hadn't had that running experience to know what signals from my body are normal or abnormal during exercise, I might have tried to push myself too hard and ended up passing out while still in the hot, humid air, and actually suffered some much worse effects. I think people too often underestimate the very real personal risks of hot weather because we as a society do such an effective job of insulating (literally and figuratively) ourselves from the discomfort of it without truly recognizing _why_ we likely evolved to find it uncomfortable. Just because we've protected ourselves better and better from it for hundreds of years doesn't mean the physics of temperature has changed, after all.

People don't take heatstroke seriously. I got fired from my last job because I got heatstroke several times driving a truck with no ac or ventilation in 90+degree weather. My current job has no ac either, and it's often nearly 100% humid. It's nearly impossible to drink enough water, and almost everyone is tired and weak because they are all at least somewhat dehydrated. Management likes to act like everyone is just lazy while sitting in their air conditioned offices. America sucks, basically.

[@thoughtchronicle]

I use to work outside in the heat. But then one summer I started having multiple heat exhaustion and heat stroke occurrences. Ever since then I cannot tolerate heat very well. Even when I am careful to hydrate frequently I have intense thirst and stop sweating. The moment I stop sweating on a hot day I feel like I'm burning. The only relief is dumping water on myself. It's horrible. I had to relocate because of it.

[@balthromaw6305]

6:40 If you are in climates with excessive humidity, you can heat stroke as well even if you are "sweating" due to the higher elevation of humidity the evaporative affects are reduced, or even stopped. This causes the bodies natural function of sweat>evap>cool down to come to a slow state or fully stop as you still sweat but there is no evaporation , thus you just get hotter and wetter with sweat but no sufficient cooling for the body to function normally. I live in the Middle US in Tennessee... the humidity here is unbearable especially in the summer, I have heat stroked just being indoors doing nothing cause the humidity is too high for evaporation from sweat to occur, causing my body to not release heat.

Asking this out of curiosity. I take a stimulant (vyvanse) , they are known to increase body temperature which I definitely notice, especially now in the summer. If a medication that increases dopamine can increase body temperature , couldn’t a medication like risperidone that blocks dopamine receptors decrease body temperature? I understand that antipsychotics would not be useful for treating hyperthermia.

Thankfully I didn't live alone, I might not have made it if someone hadn't come home and gotten me out of there.

It's more than possible to get heat stroke while sleeping, I produce a lot of heat while sleeping sometimes too - I always run a fan on me, or an airconditioner while sleeping. The Hot summers are a real pain. I never heated up the point where I actually heat stroked, but I did produce quite a bit of heat. High heat events are usually accompanies by intense dreams, there could be a correlation between the two things.

[@foxhound725]

I got heat exhaustion while mountain biking in wales in the summer. Idk if that is a technical condition or simply pre-heat stroke. People I was with wanted to ride the uphill trail the whole way. After a while I was lagging way behind, struggling to ride simple paths (bad coordination is a symptom), I felt completely lacking in energy so kept eating sugary snacks but they didn't help. I wasn't saying much/making much sense when I could force out some words. I didn't feel any hotter than i had all morning (we'd already gone up hill the shorter way and ridden down the trail once), and I wasn't sweaty. As soon as we called it and came downhill fast via roads, the breeze cooled me off and by the bottom I felt clear headed again and could tell that I had not been well, but at the time I couldn't notice it myself. Look out for people becoming clumsy, exhausted, and red if you're working in the heat!

[@arthurfelipemuckenheim851]

I'd like to point out a different viewpoint on the subject of sweating to regulate body temperature. The air around us contains moisture in the form of water vapor. This moisture is mostly measured as a percentage. The reason is that as air temp goes up, so does its capacity to hold water vapor. So our "perceived" air humidity is RELATIVE to two main factors: air temperature and the absolute quantity of water vapor in the atmosphere (denoted as the dew point, or the minimum temperature the air needs to get down to in order to become 100% saturated with water). This means that the higher the relative humidity is, the less effective evaporative cooling will be. The problem with this concept is that the water we sweat out needs to evaporate fairly quickly from our skin to effectively cool our bodies down, otherwise we'll just sweat more, exacerbating dehydration. Going with these two ideas (temperature+humidity), proper air conditioners perform double duty: they not only cool the room down, they also reduce the amount of water content suspended in the room's air because that moisture condenses on the A/C system's evaporator (i know this sounds backwards, but that's what it is). That (now liquid) moisture is then drained outside the room. I said "proper air conditioners" because there are devices that purpote to be "personal air conditioners", which are just swamp coolers. If you'd like to learn more about this, I highly suggest watching Technology Connections' video titled "Personal 'air conditioners' aren't what they seem".

[@HyperLuigi37]

What determines whether you sweat more sodium or potassium? MatPat recently did a sports drink video on Prime which has a lot of potassium but very little sodium and through some research the basic conclusion was given to him that on average sodium is lost much faster through sweat than other electrolytes, making sodium-high sports drinks like Gatorade and Powerade more effective than Prime, but is there a time when Prime would be suitable due to sweating more potassium?

[@romeoslover817]

The Sacramento Valley regularly reaches triple digits Fahrenheit in the summer. The hottest I personally experienced, as far as I know,is 119 degrees. In my opinion, anything over 95 is hot, and once it hits 100, it can be considerably unbearable for some people. But at least it is a dry heat. You do not sweat as much, but I can see that the humidity I hate so much is healthier than the dry heat. At least this is my understanding.

[@evelynwaugh4053]

No, it's exactly the opposite. You can and do perspire in a dry climate. The evaporation of perspiration in a dry climate cools one, but it isn't safe at all to do physical work in 120° weather, which is why there are heat warnings then and people are urged to only exert themselves early in the morning on those days (however, it's still 72° first thing in the morning on those days so it doesn't stay `cool' for long). But in the southeast, where humidity is high, 90° feels worse than 120° here, and your perspiration doesn't evaporate, so no cooling effect. You just stay soaked, it's gross.

[@zacht9447]

Heat exhaustion/Heat stroke/sunstroke sucks. one summer I was helping my Brother At a dirtbike race. It was about 110 degrees out and ridiculously hot. I started getting a headache but I definitely was drinking enough water, and I was replenishing my electrolytes with gatorade and other things. I then went back to my brothers house and started taking a cool shower which triggered vomiting and it was all the water I had been drinking. for some reason it just sat in my stomach without passing through.

Heat exhaustion & stroke are a concern for us as my daughter has anhidrosis - she used to not sweat at all and would pass out when she’d run around with friends in a hot day.. now she has started to sweat a bit in her teens but it is very insufficient.. The issue with the boy having heatstroke in his sleep is concerning- we don’t have AC- we aren’t allowed to have a window unit and there are no other options.. our bedrooms have gotten up to 90 degrees on especially hot days/nights.. yesterday my bedroom was 82 degrees at 8pm.. our living room downstairs was at 83 degrees. We both have fans in our rooms but it doesn’t really cool it down much when the air is so hot.. We’ve been keeping water bottles in the fridge and I suppose I should encourage her to drink more electrolytes as well.. and maybe a cool shower before bed.. She is not diabetic or overweight and we eat mostly carnivore these days once we realized how many symptoms we get from plants. I don’t know that she was ever able to sweat however we did live in heavy mold for a few years and I lost my ability to sweat for a few months during that time. I regained it but that was strange. We also have dealt with chronic tick infections which both biotoxins and tick diseases can cause anhidrosis She went to a big hospital for a sweat test and they said her sweat response was normal and they couldn’t tell us why she didn’t sweat. And no follow up or recommendations for care or how to get that body function working since her tissues were technically capable of sweating.. That was a wasted appointment.

I am prone to this and nearly fainting. Not prone to sweating even if I need to. Heat seems to build up right in my head and not get put out anywhere. I have a hard time taking showers that are long enough to wash my hair because it has a certain heat to get my hair clean, and I can't change what part of me is under the water that much because hot water irritates my eczema on my back. If it's hot enough and I go out, I can feel myself trying to faint very quickly. Before we fixed the fan over my stove, I nearly fainted recently just stirring some soup I was making. I was even more prone to fainting after having covid (wasn't easy to shower when I actually had it at all). Sitting down and putting my head down usually helps as well as opening a window but I was still fading into a faint fast doing that so I had to get my boyfriend in the kitchen instead and lie completely flat. I had thought I don't have as much of a problem with that as when I was having more circulation problems than now but I still have some issues.

Okay but people forget that your intental body temp only has to really get to 104F before serious issues start to happen. Thats 40C. Thats not that uncommon to see heat waves and outdoor advisories that exceed that number, and given the guy was laying in his bed asleep, it wouldnt take long at all for him to get hot enough to sustain brain damage. I mean average people can go from fine to out cold from heatstroke in literal minutes. The main factor is how humid it was and how covered he was. Being covered insulates you, but heat seaping is a real thing and it will just slowly roast you.
