The surprising reason you feel awful when you're sick - Marco A. Sotomayor

What actually makes you feel sick? Discover how your immune system and proteins called cytokines respond to infections.
--
It starts with a tickle in your throat that becomes a cough. Your muscles begin to ache, you grow irritable, and you lose your appetite. It’s official: you’ve got the flu. It’s logical to assume that this miserable medley of symptoms is the result of the infection coursing through your body - but is that really the case? Marco A. Sotomayor explains what’s actually making you feel sick.

But there is no evolutionary advantage to preventing others from getting sick unless they are blood relatives.

[@crispyrolls93]

Amphiuma III i don't know about that. If there are more sick people, the more likely the rest are to get infected. Plus why do you say that about blood relatives. Our brains have evolved with societal cooperation in mind. Why would this way of helping others not be a thing? Not to mention evolution is simply surviving organisms passing on traits. It has nothing to do with blood relatives as such.

I wonder if the irritability is a tribal survival mechanism to make other people avoid you, so the infection doesn't spread.

[@franzluggin398]

+Shawn Ravenfire Or it's just people being irritated because they want to do something against being in pain, and not able to do anything about it. People are generally like that, if they know what to do to make themselves feel better, they pull themselves together and focus on doing that, if not, they wish they did and start to hate everything around them.

i think is even more primitive, it may be about being more agressive so that predators dont single you out for being ill and eat you

[@abirarun]

Bob is sick!!!!! Maday!Maday!

[@DissociatedWomenIncorporated]

I'd conjecture that it's mostly just the unpleasantness of feeling ill. Any kind of stress tends to make us more irritable, and a constant bombardment with unpleasant stimuli is _definitely_ stressful. If that ended up being an evolutionary advantage on top, I doubt it'd be that big of one. You could be right though!

[@charli3s977]

Makes since thxs

[@imatreebelieveme6094]

It uses more senses than regular old text books, so that's a plus. It also visualizes the topics in a way that is most appealing and easy to wrap your head around rather than accurate. The presenter and the presentation are also paced in a way that keeps your attention up which is something that, sadly, only few teachers know how to do. It also reduces the topic down to its most important parts without handling the basics of the topic, which most of the time constitutes the boring shit you have to repeat all the time in order to remember. So, what these presentations do is reduce the topic to the things that are most interesting and important about it, which enables you to learn the most fascinating things about science without having to get through the boring shit needed to actually get to the conclusion yourself. This makes it possible for these neat little videos to achieve what many education systems around the world sadly do not, which is make education fun and show how fascinating the things education gets us to knowing can be. Just my two cents.

[@aguynamedguy9385]

I think that it's also because, since you're doing this of your own choice, you become more invested in what's happening. I'd guess that's also why jobs become less fun even if it's regarding something you love to do. Let's say you're an artist who loves to paint who sells paintings for a living. However, after a while of doing that as a job, you don't find painting as enjoyable as it was before. Even though it's a thing that you used to love doing, being technically forced to do it all the time dampens the enjoyment in the activity. However, that doesn't happen when you're not painting as a job, even though you might technically be doing it for the same length of time. Not to mention the ability to freely take a break whenever you feel like it isn't really allowed in a job much (especially not in an art-related job where you essentially need to make things 24/7 to scrape by if you're a normal person). Basically, having to do stuff makes that stuff less enjoyable, even if doing it of your own choice results in you spending the same or greater amount of time doing that stuff.

*3:09** amount of details in these animations is just insane.* Look closely - after our patient coughed bacteria to those three guys, it bounced out of second guy onto the first guy (meaning, immune system of the second guy is still good and able to fight) but then it bounced back to the second guy, meaning that immune system of the first guy is way stronger. On the other hand, the immune system of the third guy was the worst as both of the bacteria he took right away and nothing bounced. And all that secret information delivered in just a second of this incredible animation, that most of the people won't even notice. *Hats off, TED.*

[@Teh_Boi]

The first guy even backed off after our patient coughed, the detail of this amination is top notch.

[@raikojohnson9850]

What are you talking about you nitwit. A good immune system doesn't mean the virus bounces off you like some kind of tiny pogo-stick jumping maniac, you still absorb the virus, it just doesn't do as much damage. Certainly the bacteria doesn't survey your body, and turn around if it's too harsh a landscape to look for a new home like some kind of intergalactic species searching for something resembling their homeplanet that was consumed by a nearby star years ago, god damn

Honestly, the last time I had a flu, it was so bad I thought I was gonna die. Then again I *was* 11 years old...

[@WillN2Go1]

Good video. "It'll wipe out the infection before you even notice it." Tune up your symptom detector. As a middle school teacher I got really fed up with being sick at least twice a year from infected germy kids. I instituted COVID level cleanliness procedures (5 years before COVID): Clorox wipes of all surfaces in my class, and then whenever I even thought about it, I'd again wipe down desktops, chair backs and sides (where people touch them), etc. I put a two liter bottle of Purell on my desk and encouraged students to use it. Sick kids I sent to the nurse (on the one day a week she was there) or the office. They'd send them back. And I'd send them back again. But THIS is the big step. While creating lessons on how to tell the difference between flu, colds, allergies, etc. I realized that when I got hammered with the flu I'd woken up that morning and had the thought, "I might be coming down with something, I'd better take it easy." And then at some point during the day flu hit me like a truck. So in the morning instead of my energy level continually rising, it starts to taper off? I call in sick and go back to bed for the rest of the day. The first time I did this I felt like a complete flake - I didn't feel at all sick. But that night I started to get the flu headache. _Uh oh, here it comes._ Nope. Next day I woke up feeling great. I'd just beaten the flu. (Because I have asthma usually when I got the flu I'd have it for about four days and then secondary problems for another week or two.) In Hong Kong February 2020, at the beginning of COVID I had one of those experiences, but in the evening. My temperature was up, it didn't feel like anything I'd ever experienced (two sort of 'knots' on both sides of my chest). Same thing, go to bed. All the symptoms, feelings? were completely gone at 1-2am when I got up to pee. 6 weeks ago I did this again, had to skip a class I'd paid $200 for. Better safe than sorry. Next day, felt great. Hope this helps.

[@jem5691]

Great points and I'll echo that: be aware of your condition, listen to your body and watch out for early symptoms. Sometimes I'm feeling a bit "off" and YES, it is always worth taking it easy, and staying home if you think you're getting sick. Cancelling your other plans and resting in bed not only can prevent sickness, but imagine if you were about to go to school, or the office, or to see friends ... you might be infecting them!! It's smart to stay home when you're feeling sick or when you feel like it's coming.

This is a great video. Far too often we want relief from "problems" without knowing the extent of what will happen when we do that, or why they are there in the first place. If you are able to recognize the complexity and organization of the human body, you will have less interest in controlling its processes, and more interest in helping it do the things that it is so innately capable of doing on its own.

There is a theory that this is due to viruses remaining in the thyroid even after the body has eliminated them elsewhere - general disruption of the nervous system due to chronic or acute stress can also play a part. Your body is trying its best.

How did we figure out how to create these machines that give us these in depth looks into the body and testing results and just.. It's insane how our body is so extremely detailed and intricate and we've figured out how each small piece works along with the others. All .... Very interesting.
