How To Identify, Prevent and Treat Heatstroke - Doctor Mike Hansen

Heat stroke can occur suddenly, without any symptoms of heat exhaustion. If a person is experiencing any symptoms of heat exhaustion or heat stroke, GET MEDICAL CARE IMMEDIATELY.
Depending on different factors, heat can cause someone to lose 1-2 liters of water through sweat. This is why the recommendations for hiking in peak daylight hours of the grand canyon during the summer, is to carry one to two liters for each hour on the trail, so that’s 8-16 pounds of water for a 4 hour trek.
And if you’re not replenishing with enough water, dehydration kicks in, then overheating, meaning hyperthermia. At this point, the body is going to start to divert blood to the parts of the brain that are more basic. Which means other parts of the brain get less bloodflow, like the frontal lobe. Now your in heat stroke, and your capacity for decision making diminishes. And later, the delirium kicks in. Followed by crashing to the ground, and quickly dying, unless there is emergent medical attention.
Her tragic death could have easily been prevented. But no one thinks they will ever suffer from heat stroke. But temperatures are climbing all over the globe, and you don’t have to be in desert summer heat to suffer from it. Especially now-a-days. Just recently, former NFL player Marion Barber died of heat stroke. And you have this 24 year old UPS driver who died of heat stroke. Thankfully,…….. this UPS driver survived.
In the US, more than 600 people die from complications of extreme heat every year, and with global warming, that number is only going to get worse.
What is Heat Stroke?
The diagnosis of Heat stroke can be made when you have 3 things
1) You’re out in the heat
2) You have elevated core body temperature, usually in excess of 40.5°C (105°F)
3) Your brain is malfunctioning
The scary thing with heat stroke that really blows my mind, besides it often being fatal, is that it can happen so quickly. In some cases, only 15 minutes. There are two types of heat stroke:There’s the classic heat stroke - aka Nonexertional heat stroke. This is the one that occurs in people who are predisposed to having difficulty regulating their temperature. Who would be more likely to have more difficulty regulating their temperature?
People at the extremes of age, or with certain medical conditions like heart disease, neurologic or psychiatric disorders, obesity, and the use of alcohol or cocaine, as well as certain prescription medications. Then there is exertional heat stroke, which usually occurs in young, otherwise healthy people who exercise in hot temperatures for too long. Typically athletes and military recruits in basic training.
How can you tell if someone is having a heat stroke? Besides being hot, heat stroke patients are breathing fast, have a fast heart rate, and typically a low blood pressure. The brain is affecting in some way. It might be something as mild as feeling weak and tired, but there can also be nausea, vomiting, and dizziness. There can be confusion, slurred speech, disorientation, delirium, and if extreme, loss of consciousness, along with seizures and coma. The skin usually has flushing, from the cutaneous vasodilation. And the skin may be moist or dry depending upon underlying medical conditions and hydration status. I should say that most but not all victims of heat stroke are dehydrated.
Let’s say you come across someone who is suffering from heat stroke. What should you do?
1) call 911
2) Stay with them until emergency medical services arrive
3) Move them to a shaded, cooler area
4) remove outer clothing
5) if they are able, drink cold water
6) cool them as quickly as possible
o ideally with a cold water or ice bath
o Wet the skin
o Place cold wet cloths on the skin
o Soak clothing with cool water
o Place cold wet cloths or ice on the head, neck, armpits, and groin
7) Fan them to circulate the air around the worker to speed cooling.
How is heat stroke prevented?
1. avoid outdoor activity during peak hours of the day (10 am to 4 pm)
2. Drink plenty of cool fluids, such as water or sports drinks, so you do not feel thirsty. But don't force yourself to drink very large amounts of water in a short time to the point that you feel uncomfortable, because this can be harmful. *Sometimes people drink too much water, without consuming enough salt, which can lead to water intoxication. The medical term is hyponatremia, and when this happens, you can feel very tired and weak, confused, and in extreme cases, experience coma and death.
3. Avoid diuretics (alcohol, caffeine, medications, drugs)
4. Wear loose, light-fitting clothing. Don’t forget sunscreen.
5. Wear White colors to help to reflect the sunlight off you
6. If you need to be outdoors, consider getting a cooling vest

Heat stroke is no joke. Decades ago as a teen in a hiking summer camp, we had one group member 17 years of age collapse on an exposed ridge because he didn’t want to drink water. He was somewhere between exhaustion and stoke. He had to be tended for a few hours until he was cooled and rehydrated. It wrecked our ability to reach the night’s campsite.

[@shootingbricks8554]

Heat exhaustion can generally be treated.

[@lizziesangi1602]

One summer job I had the worst job of my life, assorting hangers in a Korvettes' warehouse. We stood in front of a table and assorted different sized hangers for 8 hours. There were 2 fans blowing on the workers, (women). I got heat prostration and was out for two weeks. It was bad. We had no AC at home, was in bed for two weeks and that probably could have been averted had I drank water. But this was in 1974 and sadly and unfortunately drinking water was not promoted as it is today. Thanks, DR HANSEN Shared!

[@user-yg7ps4gh1x]

I grew up outside of Tucson Arizona on a ranch. Summer heat can reach 118 degrees. There are basic rules to follow. There you learn to drink every time your mind thinks about water. You don’t wait for your body to tell you are thirsty because that is too late. The second thing you learn is to stay covered- wear clothes to protect you from the sun. Your perspiration will collect in the fabric and cool your body. And the third thing is to avoid drinks with alcohol. Alcohol pulls the liquid out of your body.

[@flagmichael]

Great point - if you think about water you need it.

[@lizziesangi1602]

The clothes absorb the bodily sweat and cools the body? Never have I heard that but find it fascinating. Thinking about it, the clothes do dry fast enough on the body - it's not like they remain wet causing the body to become cold, (even in the heat we don't want a cold body), and sticky. I will never think the same about sweating up a storm, again 😂 Thank you

This is a huge problem in Australia also. With our summer temperatures sometimes reaching past 40ºC (104ºF) during the day. Some of the worst days I've experienced have actually reached over 120ºF; these are definitely not the conditions you want to be outside in.

[@gabrielhung1647]

Thank you Dr. Hansen, this is a nice topic for the recently heat waves attached the globe. We have to aware of the heat stroke.

[@LFTRnow]

Very good info overall. I'd add that it doesn't have to be an "ice" bath. Short answer: A bath of any water or a shower of any water will generally offer considerable improvement. Usually simple "cold" water, even if it is 35C/95F will do a lot to improve conditions. Water conducts heat extremely well and doesn't heat up very much when doing so. Also, when water evaporates (both coming out of the shower head as well as off of you) it cools a bit further, giving you an even lower temperature to work with. It is also far less of a shock to the body if you can use gentler temperatures. Obviously, water that is warmer than the patient will do little to help, though it can be applied to give evaporative cooling (ie sponge baths. If doing this, use a fan if possible to aid evaporation..

[@comedianmattrossey]

[@lizziesangi1602]

@ i rivas Two days ago, at Walmart there were Air Conditioners for $55 and small units I'm not familiar with for $44. PLEASE, get yourself an Air Conditioner. It's not worth it. My AC broke earlier this summer and it was like 100° in one room. You can die. With energy savers, you being out all day, you CAN effectively keep the monthly electric down. Please, get yourself an AC, you deserve it! Why don't you deserve an Air Conditioner? There's an heat advisory where I live this week - 95 - 105°, 90 - 100°, that's not real feel. The heat is no joke, as you're experiencing! Please, get yourself an AC ❤

[@marygem]

If you find someone suffering from heat, you must become proactive to cool them down. Throw them in a shower, get ice on them, anything to cool them! They can't think.

[@flagmichael]

Good advice! They will recover from getting wet, but may not recover from heat stroke. As you say, people getting close to the edge will not think straight. Before I retired from an Arizona electric company a line crew noticed three young adults walking across a field in Phoenix... one of them was stumbling noticeably. The one who was stumbling refused all help until a lineman offered him a couple of bucks to drink a bottle of water. After he drank the first one (and the linemen had set up portable shade) he accepted two more. By then he was alert and able to see to his own needs. I have no doubt he would have come to tragedy in a few minutes without their intervention.

I just had a situation with my 4 year old grandson. We went to the NASCAR race at Pocono Raceway a couple of weeks ago. I brought a lot of ice water and frozen Gatorade with us because I knew it was going to be extremely hot there. I also brought a thermometer. It was 100.8° in our seats. My grandson got quiet and wanted to go home. I noticed that his face was red and he wasn't sweating. I immediately started pouring the ice water on him and after a few minutes he was back to his normal self and his face wasn't red anymore.

Exposure to wet-bulb temperatures of 35 °C or higher over 3-4 hours can result in multiple organ failures and death. The wet-bulb temperature is the one under a wet fabric, so it includes any heat removed by sweating or any form of evaporation. Those temperature are now reached in certain parts of the world from time to time and leaving the cooled areas is a serious health risk.

[@johnedwards315]

what a relief! Getting back to learning things. Had all these symptoms today living in southern peloponnese. I need to take diuretics because of a previous stroke and I am a coffee lover.

Kick the love of coffee my friend. If you're living there full time, the heat alone for your condition isn't gonna be a good thing. Why add to the risks. There are other things you can drink similar to coffee that don't have the caffeine, Chag. It's a fungus that grown on trees. Much healthier than coffee is and same kind of enjoyment.

I've found a very effective way to keep heatstroke at bay. For about 10 years now, I've used a water-soaked mid-sized terry cloth towel wrapped around my neck and/or head. The constant evaporation effect makes you head and neck feel wonderful. The cooling effect appears to cool my blood. I stop sweating as much overall and get to carry way less water while doing activities like working out outside in 100+ degree weather (which I do 😊). Before I started doing this, I did have times when I did get dangerously close to getting heat stroke. After wrapping my head and neck in a soaked towel, I've not come close to it under very extreme temperatures.

Heat exhaustion happens when the body is overheated, usually with a fever of up to 104 degrees Fahrenheit. One of the differences in symptoms between heat exhaustion and heatstroke is sweat; heat exhaustion is characterized by heavy sweating, while those suffering from heatstroke experience decreased sweating

Thanks for discussing heat stroke… please consider a video all about salt. Iodized table salt vs non iodized … how much iodine do we need daily … I heard Celtic salt is better as well as pink hymalayian salts … then the 2300 mg of salt a day limit topic … how can it be achieved if at all? and lastly … how does our salt consumption vs water intake both alone and with our food choices effect the body s ability to avoid heat stroke. one more thing … sweating … some people do not sweat … still another variable … ps there are lots of no salt added products out there now which I am finding helpful…

[@stanj7223]

Plain old sea salt works fine, or Redmond Real Salt. Some of the pink 'Himalayan' salt is mined using (basically) forced labor, so I won't buy it or support it. One benefit of sea salts is it's a mix of metallic salts that are nearly identical to your blood concentrations, as opposed to sodium chloride 'table salt'. Most people get too much sodium and not nearly enough potassium.

It was an electrolyte replaced with glucose, which was lemon flavored, glucose sweetened, and and contained a proportioned blend of electrolytes. The first time I came across it, was at the finish line of an AAU, half marathon. I finished and they had tables of 8-oz glasses set up. It was fall in Vegas, but still 90-degrees out, and I was dehydrated. I was half way through the fourth glass, when it suddenly tasted like lemonade with salt in it, and I made a sour face. The guy from the company laughed and told me that it was a design feature. When your fluids and electrolytes came back up, it suddenly tasted bad. That way you didn’t drink too much and flounder. It was only on the market for a year or two. Gatorade was much cheaper, and tasted better.

Is it just me, or is excessive use of air conditioning more common now compared to when I was a child in the 1970s and 1980s? So many buildings are kept so cold in summer that I have to put on a light jacket while inside. There's a defacto dress code that's at odds with the weather outside. I can't help but think that air conditioning abuse INCREASES the risk of heatstroke by reducing adaptation to the heat. Admittedly, 100-degree heat is potentially dangerous for everyone. However, it seems to me that the people who keep their thermostats at 72 degrees or less during air conditioning season are at more risk because they have no adaptation to the heat. 100 degrees to someone who's used to 72 is like 108 degrees to someone who's used to 80 degrees.

Given that I'm in summer mode, 69 degrees would be bone chilling to me. I'd definitely need a jacket at that temperature. Where is this visitor from? Somewhere north of the Arctic Circle? 100-degree heat is ideal weather for watching movies featuring lots of snow and ice.

@@pualenaisz4403 Wow, it sounds like your home is extremely well shaded and insulated if the indoor temperature topped out at only 80 degrees when the air conditioning broke. I would have expected the indoor temperature to climb at least into the upper 80s without the aid of air conditioning. I'd expect people in Texas to be well-adapted to the heat and have a level of heat tolerance that's superior to mine. Admittedly, I'm skinnier than most of the population, but my idea of room temperature in winter is down in the mid/upper 50s. (You can bet I'm wearing a sweater and long johns in deep winter.) I'm enough of a couch potato as it is in winter. If I insisted on a 72-degree indoor temperature in winter, I'd have difficulty adapting to the cold, and that would make the outdoor environment even more hostile. Having an aversion to the great outdoors can only make it more difficult to get enough exercise. I need more exercise during the warmer months to compensate for my sedentary winter lifestyle. How can your human polar bear visitor stand to live in Texas? It sounds like he/she cannot spend more than a few minutes outside even in normal summer weather. How can he/she ever go for a walk, visit an amusement park, go to an outdoor concert, or go to a summer festival?

It isn’t only the generalized use and abuse of AC. It has also to do with poor dietary choices (particularly, high consumption of salt/sodium and low consumption of potassium), avoidance of prolonged physical activity at warm temperatures, low aerobic capacity, overweight bodies, etc.

Yup it does. And there are other ways we can use that also cool the indoor air just as effectively, without the need to use aircon or electricity.

No reason why the rest of the world can't do the same.

I totally agree with you on adobe built homes. They are even good in cold climates for retaining heat in. I've got a friend who built and owns an earthship home and he has wind tunnels that cause a constant movement of warm air being expelled out of his home to the outside and it draws cool air in from the dark side of the house. I've been there and it works really well. He doesn't have to worry about heating the place so much but on the cold nights in the arid area he lives in the Nevada desert, he just closes the vents with a hand crank and lights the fireplace and the whole house is evenly warmed. He's got it down to a science.

There have even been Adobe structures unearthed during archeological digs of early human homes. Earth Ship homes most times are partially made of adobe. They're countless other old world building methods that are still used currently by people in different countries. In the Philippines people still live in Nipa Huts in areas that are far from cities and are more rural/country areas. Thailand, Vietnam, and the Philippines, again in the more rural areas, use bamboo for the entire building of full houses, including the furniture. They even use it for plumbing fresh water from a river to a bamboo hut.

You need to acclimate yourself to heat, it takes a few weeks. Also, I read that many people who were force-feeding themselves water, trying to protect against heat stroke, actually make themselves more susceptible.

[@flagmichael]

Acclimatization is much more mental than physical. The requirement of water in hot climates is everything. The only caveat about consuming lots of water is to include electrolytes; without it we invite heat exhaustion (very different from heat stroke) but if we fail to drink the water we invite heat stroke. Drink the water; the outcome of heat exhaustion is almost always a lot better than the outcome of heat stroke. (Lived, worked, and cycled in Phoenix for 27 years.)

[@davidr9876]

@@flagmichael I beleive your body actually reacts differently to heat after acclimation. I live in MD where we have 4 seasons and also did triathlons here. When summer heat comes, it hits you hard at first but after 2 or 3 weeks it's much easier to stand. There was a study (that I can't source) that looked at the number of people needing ambulances at 10k races, bike races etc. These are people like myself that are not true athletes, mostly weekend warriors. They determined that when people forced themselves to over drink in preparation for the event, they were more likely to need medical intervention (probably heat exhaustion as you say) than those that drank when they felt thirsty.

A high-sodium diet impairs heat acclimation. Heat acclimation has nothing of “mental” but rather is driven by adaptive physiological changes such as the hypertrophy of the eccrine sweat glands, an enhanced capacity to sweat, an increase in the re-uptake of sodium (aldosterone-mediated) and other ions from the filtrate in sweat glands and kidneys, etc. I’ve lived without AC in a warm climate with high relative humidity (on the Mediterranean coast) for almost five decades.

[@ptg6202]

So how does this differ from heat exhaustion because it sounds the same...

[@gitmoholliday5764]

whow... just at the end some warning about Water poisoning. distrust everybody telling you to drink 2 liter of water without also telling you to refill on electrolytes / vitamins etc..

[@flagmichael]

Drink lots of water before you need it, and include some electrolytes (I learned that the hard way - 3 quarts of water but no pee, and I was getting more and more fatigued.) There is no substitute. When I lived in Phoenix a cyclist suffered heat stroke a couple blocks from my house. He was in the shade of a tree when EMS showed up; they were beginning to get his story when his temperature spiked and he died in front of them. Be aware that a lot of incipient victims will resist suggestions that will save their lives. You can't go against their wishes when it comes to their body or actions but you certainly can and should call 911 to get the professionals involved.

Heat stroke results in runaway body temp yikes.

[@polyanthesis]

I had heat stroke as a child and I still have trouble with heat 30 years later. I need to take electrolytes all summer.

[@briangriffiths114]

Very useful information given that when I was studying climate change 12 years ago, it was expected that it would take several decades for the planet to heat up by an additional half a degree. Instead, this has happened in only ten years.

[@Reaper6x8125]

Is heat stroke the same as getting sick from the heat ?

[@flagmichael]

Getting _really_ sick from heat is usually heat exhaustion - flushed face and serious fatigue. Getting sick from heat can be a number of things, including loss of electrolytes through sweating. Heat stroke is a medical emergency but any debilitating condition should be checked out by professionals. Heart attacks can hide under cover of heat exhaustion.

[@Jo-ys5le]

How many of these had the "you know what". Could the blood clot increase have something to do with it also?

The longer you are out the more water per hour you will need. A 5 hour event needs more water per hour than an1 hour event.

let's stack up the number of young people dying from heatstroke to those that just happen to, well, drop dead, which seems to be happening an awful lot lately. Five or six young doctors died in Canada in July, not exactly the hottest place on earth. Something else is going on, but you surely won't hear about it here.

[@Jo-ys5le]

The 5 to 6 doctors were from the same healthcare. They may have had a bad lot. I read it was the 4th "you know what" to get ready for the next pandemic. What makes me sad is the number of babies that are being born without limbs.

[@immortalsofar7977]

According to modeling, the increase in temperature due to climate change is only ~2C over the next 50 years. So, don't blame this on climate change, but rather weather.

[@flagmichael]

Most land is under the influence of oceans. In North America the West is dominated by El Niño, a weather system driven by South Pacific currents. Here in Arizona it is King. While people were blaming the dry weather on climate change El Niño brought enormous amounts of water from the Sea of Cortez last week and dumped almost ten inches of rain on forest burn scars north of Flagstaff, causing massive mud flows. In East Flagstaff we barely had three inches of rain that week.
