if I pass out while playing sports, by all means pour ice water on me, but put away the rectal thermometer...

Why TED-Ed get much less views than other education channel, when they provide superior animations and narration.

I had heatstroke once while hiking. I somehow managed to walk all the way back across town to home (which took more than 30 minutes but I think any damage I got was negligible) and immediately took an ice shower. I had my phone out and ready to dial 911 on the walk home. I'm damn lucky I didn't pass out in the middle of the woods. Determination is a hell of a drug. Heatstroke feels like your body is cooking from the inside, like you're just radiating heat. Also there's the throbbing headache, and sometimes your vision might go wonky. If possible, bring ice with you on long walks and keep your phone charged and with you. In an emergency, you can apply ice to the neck, armpits and groin. They're the areas with the most blood vessels... or something.

This is how my 2 year old brother died. Before I was born, my parents left him in a hot car, which killed him.

So basically, if someone has a heat stroke, throw them into the Arctic Ocean for a couple hours.

i got this during a big heat wave i was in line for a water ride and i was dehydrated hungry and extremely hot i passed out it was the scariest thing that's ever happened to me i got dizzy and no matter how hard i tried to open my eyes everything just got dark
Colonel Angus
Yea, cause i just casually carry around a rectal thermometer with me...

So basically you get so hot that you begin to cook.
This one time a student senior on the soccer team had heat stroke. Our coach recognized this pretty quickly and had him jump into a cold shower while calling 911. What do the paramedics and hospital do? They ignore the warnings of our coach that he has heat stroke and basically say, "There's nothing wrong with him. Just let us do our job and we'll fix this when we find something out." Apparently his organs were permanently damaged and he really did have heat stroke like our coach said. Instead of trying to fix it immediately, they waited a few hours. Stuff like this makes me angry.
1:21 cmon we all know we were all waiting for him to fall off his bike
Just don't try to measure temperature yourself, if they find you unconscious with something stuck in your butt, you might send investigators on the wrong path :)
there was a girl in my school that was running in PE and apparently she just fell on the floor and died. Now everyday I think about how I'm walking over the area where a girl fell over and died
That face at 2:10

my body overheats all the time something's wrong with my hypothalamus. it's a very scary thing. I'm always sweating out of control and everyone else seems to be fine even on a cold day
Elmer Ramirez
You call it heatstroke, I prefer the term "over clocking".
If we get injured or have a heat stroke at our school nurses are just like “GIVE HIM A WATER AND SALTINE” but I wonder what if you fracture your skull somehow at my school will they still just be like “GIVE HIM A SALTINE”
Fazeed Kotta
mum:why don't you do sport?! me:err I don't want to get heatstroke
Kyle Dilbert
"The most feasible and accurate way to measure tempurature is a rectal thermometer " so ,stick a thermometer up someone's butt ?
Adam Stewart
I remember getting heat stroke on a coach in Belgium. I had to sit through it xD
I would probably get a heat stroke if I see Scarlett Johansson in real life.
But... but my mom always said you shouldn't jump in cold water after exercising. I heard this kid in my hometown played some soccer and then went and took a cold bath and apparently he somehow died because of this, is it possible or it's just bullshit, or maybe it's different when having an heat stroke?
heat stroke frickin sucks
Actually no you do not want to cool quickly under any circumstances, you need to cool at a slow but steady pace and of course treat for shock
Keneisha Pinto
Hmm...I wonder wher we'll be able to find a bathtub with water and ice in the middle of a playing field
This is an excellent educational video. Should be used in all schools and sporting organisations.

A rectal thermometer, did I hear right?
somebody has a heat stroke what do you do? i would destroy the sun. wait that would kill everyone from intense freeze. i will just stick to walking past. and say i didnt see nothing if police question me. i would probably drag the body when no one was looking and then use it as a punching bag. (need to get into fight club ) what the hell was the point of this comment?

Poor undyne now I know what happened :( thankfully I dumped water on her.

1:11 Those chin ups almost gave me a heat stroke xD
I dealt with this a lot in the Army as a medic (even received a medal for saving two heat stroke patients and an allergic reaction patient all at the same time. I was with one other medic and a couple other soldiers.) great video on what and how to identify and treat. But it is also 100% preventable. Hydrate, hydrate, hydrate, know your level of fitness and limit your exertion accordingly. Oh and Hydrate some more!!!! :-)
For someone who goes bike riding every weekend and lives in a tropical country, this video is really helpfull
Eefje Poppelaars
Just did some heavy mountainbiking in 40 degrees celcius the past few days, and I got a bad headache each night. The thought that I could have gotten heat stroke is scary.

So... you are saying the third highest cause of death is 100% avoidable? So like we survive the stroke and die. kek

I got a classic heat stroke once. Not fun. I thought I was going to die.

Well now we have ANOTHER reason pe sucks
exertional heat stroke is one of my favorite types of conditions: Where the primary symptom is also the most essential part of treatment. You get it from exerting yourself way too much, and what happens? You pass out and stop exerting yourself. Sure, you may die without help. But you would've definitely died if your body just keep on going.

Douglas Casa was the guy who ran the race, right? The video is narrated by Douglas Casa...
Glad Ted-Ed kept the use of both metric/imperial but especially metric. Keep it up.
Ushida Sakura
I feel like I had heatstroke then fainted for 5 hours I think...I suffered I got tired easily just for one minute just for walking....
Zach VanAlst
The body and how a heat stroke affects the body is interesting thing that I didn't know just how much of a risk it puts on the body. The body runs through a number of different methods to protect the body and keep it from shutting down. It tries to get the body to a safe state. I didnt know just what the heat stroke does to the body, it puts risk on kidneys and other organs all throughout the body, I always thought it overheated you, never knew it hurt organs and many other parts of the body. The overheated state of the body is always dangerous but never knew it could do the things that this video states.

I love your voice! 😊
I had a heat stroke once, i was playing mini golf in 100 deggre weather for 2 hors. No one else felt as hot as i did but then right when we finished, I got dizzy and i almost collapes. The Hospital was not called and i was not cooled down but then i was walked in side the Arcade i was at and i got a soda. i didint order the soda but really i could care less, if it had ice in it it's okay. I ended up cooling dwown enough that i wasn't dizzy but then I started puking, because it was soday and well... let's just say it dosen't sit well when having a heatstroke. We ended up just going home, but then a few hours later i started javing a little trounle breathing. It's still going on today, but i've never told anyone i can't breathe that much anymore. THe reason i dont tell them is really because it's not too bad but i will probaly tell my parents sooner or later.
Thank god I sweat frequently there's no way I'll get a heatstroke
Gabriel Aponte
This used to happen to me very often during field days, I used to drop to the ground after running because of the heat... What made me feel better was me being given a cold soda in my head and going for some shade (avoiding the sun).
Joshua Kelley-vinton
I know some of you guys are going to think oh l shouldn't exercise but it's okay just drink lots of water before you do a lot of exercising

I had a heat stroke in track. We were competing with other schools and every other student in 9th grade came to the stadium; they gave us one water bottle because it was hot outside and - well - we were running. I, the dumbass, decided to save my water. I didn't feel thirsty, and I eat until 3:30 pm. I started off strong : Jumping, Sliding, gliding, sprinting, jogging. After it ended, I collapsed; idk what happened next because the doctors told me that I had memory loss(yes, they also treated me for a heat stroke). What my friends/witnesses told me was that my head slammed into the grass, one teacher (Mr. Thomson) actually carried me to the school's Doctor called an ambulance and my mom, and that's all not much. I wasn't close to death, but I still had to be treated.

I think I may have had a heat stroke. My vision got oversaturated and blurry, then it went to all yellow and I collapsed. I couldn't move and had to be carried home, and then I threw up. Was that a heat stroke?

I'm sort, but one of the worst things you could do is to put them in ice water! This will put them in shock! Yours truly An Eagle Scout I've also trained for this as a lifeguard. You cannot cool people down that quickly. It must be slower.
My cousin had a heat stroke at Canada's Wonderland after walking around for more than 5 hours. I was with her, we only had a break when the cold air it us on the roller coasters.

Once I was in a run club in school many of my classmates were hot because summer was near and we were outside. I was crying because it was so hot outside.😭
My sister has had three heat strokes. This is good to know in case it happens again, because at the time we didn't know what they were.

I got heat stroke once and my left lung felt like it exploded so we had no idea what was going on so I used my inhaler and sat in a air conditioned truck and was fine
Saeed Zafar
Why not adjust sport matches at Summer nights, or in Winter days, avoid Heat Stroke and Cold Shock both.
Miss Purple
Swimming is a sport. So you can get a heat stroke
2:35 ...Well that seems a bit obscene... 2:39 Nevermind.
is it normal to feel some symptoms of nearly heat stroke while its cold outside but when you are wearing too warm clothes? i heave some problems with my heart and i think i dont need 40+ celsius outside to get some symptoms of overheating, sometimes i feel way too hot literally even when its cold outside
I have had heat stroke several times in my life I didn't even know what was happening

Sometimes school are sometimes evil and not taking sure if they don't know about heat stroke.
I'm not very creative
My sister was lightheaded and probably unconscious for a while on a holiday in Spain. We walked a damn lot to a nearby town where she got dizzy. Would that be a heatstroke?
Lil Hez Official
so is this a example of hyperthermia ? or does that only count when the body undergoes cold conditions

Is it really necessary to conduct a rectal thermostatus? Regardless of the heat stroke severity, the body needs to be cooled down
