5 Myths About Staying Cool While Exercising in the Heat Exercising in the heat is serious business. F or obvious reasons, overheating is not good. Your body fatigues faster, you might feel nauseated or dizzy, your head might start to ache, and, in the most serious cases, your organs might even begin to shut down. Myths and facts on how to stay cool in the heat While that’s a myth, Doctor Beltran said if you’re exercising or working in the heat, you can replace those electrolytes by cutting a sports.

Staying active, even exercising in hot weather, can be done safely, but you really have to pay attention to the environment and your body to make sure a good thing doesn’t go bad. Here are a few tips for exercising in the heat: Know the weather. If you haven’t been exercising in hot weather already this summer, don’t choose a hot day to. The most common piece of advice about exercising in the heat is drink, drink, drink water, not caffeine-loaded sodas or beer. Roberts says you can get heat exhaustion even if.

Whether you are exercising in warm weather or in a steamy gym, you are more at risk for overheating. Learn how heat affects your body, and get tips for staying cool when it is warm out. Being prepared can help you safely work out in most conditions. Be sure to stay hydrated, Amato said.

Dizziness or a racing heart could be a sign of heat exhaustion. In that case, get out of the heat, remove your mask and seek medical care. Actually dry heat is a little better than humid heat. It allows better evaporative heat loss during sweating to cool your body temperature. However, if you are sweating a lot even in dry heat that may put you at risk for dehydration which ultimately can still lead to heat stroke. Myth 5: It doesn’t matter which part of the country you live.

“Heat exhaustion and heat stroke can both occur while outside on hot days. Therefore, it is important to stay hydrated and stay cool,” Dr. Janette Nesheiwat, family and emergency doctor.

While some of you might be sipping frozen margs by the pool, or basking in the cool temps of an AC unit, for the rest of us it’s about to get real hot. 7 Genius Tricks for Staying Cool. Heat Syncope is weakness, fatigue and fainting that are caused by too much salt and water loss through perspiration during exercise in the heat.

This is normally caused during the first 5 days of adjusting to a new activity, and can be complicated by taking diuretic medications or a previous heat-related illness.

To make matters worse, high-intensity workouts increase core temperature more than lowto moderate-intensity rides, especially if you’re riding indoors, and sweat evaporating off your skin is your body’s primary cooling system.

Many athletes sweat profusely even in cold environments, so the clothing worn (after warm-up) should be as light as possible in weight and provide as little barrier to passage of water vapor (sweat) as possible.

  • I workout very effectively in the cold… I’m Alaskan and during the winter -20F outside and I’m doing bodyweight exercises wearing nothing but shorts

  • I feel like once I started to get an exertional heat stroke but idk. I went on a bike ride to a garage sale with my brother during the summer. It gets insanely hot where I live, and that day it was about 102°. We biked (mainly uphill) for an hour with one break. We noticed the garage sale was closed, and while we were heading back, I was exhausted, my head was throbbing, and I was breathing really heavy. My brother was very light headed and we both felt like we were going to pass out. We stopped at the nearest convenience store and got some water and we got home alright.

  • just went thru this…. cut grass at 8;30 am but after 20 mins i felt like i wanna fall out…weak like… stop cuttin grass sat down and got some water…still felt like i wanna lay down…after 10 mins felt better…cut grass before 8 am or after 6 pm… dont fight the sun… you wont win…almost felt like praying…i made it though

  • Awesome video! Hey Peyton, is Gatorade good for the body? I heard it has too much sugar in it! Just thought I’d ask you to see if you might know if it’s good or bad for the body. And or weight. Thanks

  • Thanks for making this video! I learned a crapload from watching this. I usually run outside and play tennis in the heat since I live in Texas. It’s been 100F for quite a while now, and I never knew about the shower trick, or the compression socks. I’m going to try to do better with drinking water before exercising, cause I get lazy sometimes and just go running without truly hydrating. Thanks again!

  • Hi Doctor…. please I have a question…

    Anytime I’m hot or stressed out my body starts to preak me… I feel like pins or needles are poking me in all parts of my body….

    Please help…

    I’ll be awaiting your response

  • Thank you for your videos man, I’m about to go through 4 cycles of e & p for stage 3 testicular cancer and your videos are deff helping me. I’m hoping I can get my muscle back as good as you did when I’m finish with all this, stay strong brotha!

  • I think I had heat stroke today. We did a hike that we underestimated. Didn’t bring enough water, my urine was dark and we grabbed a water bottle filled it with water from a fall for my daughter as a gift. After less than 10 minutes we needed to poor half the water on my head. We did that for about 2 minutes. I used to wrestle in high school and this is the most exhausted I ever felt! heat stroke is not fun!

  • Bruh I literally got heat stroke today and I went to a cold spot drank a lot of cold water and just stood there and the only way I knew was because my body didn’t want me to move also because my heart all of a sudden went faster

  • Thank you for explaining this to me the guy I work with because I do trash he told me tomorrow +80° he told me I have to wear a suit anyway to check in on top of it in a winter hat to cover my face is this dangerous because he told me I have to work as he doesn’t with the virus what would happen if I have to where it will I get heatstroke

  • I have terrible fluid retention since going vegan 8 years ago, it happens everyday, what could it be from, i don’t add salt, and drink plenty of fluid…i am wfpb, no junk. I do consume stevia. Any ideas would be great. I do workout 6 days a week as well. It is nonpitting edema from the waist down.

  • It’s the worst feeling you feel like your gonna die shallow breathing nausea and throwing up I was a mover in 105 with alot of humidity I started throwing up I’m barely getting better I hope this was yesterday I didn’t go to hospital

  • I had mild heat stroke in Venice August 2018 it was about 36° and I had a killer migraine, and I threw up, worst 6 hours of my life

  • Sucks playing football (soccer) in Arizona. I’ve had times where I feel like I’m on the verge of getting a heat stroke but luckily I’ve been able to push through until I can overdose myself with cold water.

  • I almost had a heat stroke not from sport but from cooking, i was in class and i was feeling quite hot and i felt like i was about to pass out and the last thing i done was Puke, i skipped the last lesson because of it

  • I AM serious. But, then again, I guess if you’re exhausting yourself without drinking water anywhere, you can become dehydrated. I just experienced it for the 1st time…

  • Absolutely. I love all of Yuri’s information. He’s inspirational. A video like this is actually perfect for me because I often exercise while outside in the heat while wearing nomex coveralls. So I LOVE this information. He just needs to fine tune how to deliver said information. I tend to zone out while I’m waiting for the payoff. He could easily edit something like this down to under 10 minutes.

  • is there any other source of electrolytes besides coconut water and sport drinks? i can´t get cocon. water here and sport drinks are full of sugar and other junk.

  • This is so interesting! The big problem I have is retaining the water. We live in a dry, higher altitude area, and it goes right through me, so it seems like I’m constantly dehydrated!

  • Yay! Im so glad for this video! I live in Phoenix and that has been a problem every summer because it is in the 100’s and i hate cardio in a gym. Was super excited about the topic so i commented before i watched the whole video…so i hope you got some helpful info:-)

  • i have a question…if i decide to do let’s say 5 days of waterfasting with 30 minutes of light jogging every day (so a bit of sweating), will there be problems with this whole electrolytes-thing?

  • oh my GOD you cover topics that all other fittness channels avoid…therefore just about all your topics are HUGE questions of mine. I hate postponing my workout to sunset where i am naturally more fatigued at the end of the day. and for the afterburn that im getting from my workout wouldnt last through any other meals i would eat later in the day as ive usually eaten dinner by then. thanks for the video!

  • Ive been running in the cold for like 3 days now and my chest has been hurting so I searched this up is it good to run in the cold ahaha good info btw dude ��

  • Just had a short one, threw up a bit. Scared my parents, all good now. Needed to make sure wtf just happened cuz this happened inda past, friends said it was heat stroke(they were there when it happened)

  • Correct me if I’m but I don’t believe immediately dunking someone in ice cold water would be really beneficial since there’s a chance that they could go into shock.
    I think you also need to give the person fluids, if possible. Just a little bit at a time so they don’t vomit.

    They say something similar when it comes to hypothermia, where you need to gradually warm up the person. You don’t put someone under hypothermia into a scalding bath.

  • yes… you got pissed off fast when working in hott sun people yelling…yes blood pressure is to the roof and burning up…. must chill out

  • TedEd, just wanted to let you know that heat stroke or heat induced seizures are common with people with Epilepsy like me. Just wanted to let ya’ll know.

  • I remember getting a test question wrong in elementary when asked to list foods that have a high water content. I wrote oatmeal because we added water to ours. Seeeeee I should show this video to that teacher telling the fluid in the oatmeal counts!!!

  • Mexicali ( capital), Baja California Norte, Mexico. 3° F 5° F (115° F today) higher than Pheonix, Arizona.

  • sense of impending doom
    muscle tremors
    rapid heart rate
    rapid breathing
    muscle cramps
    lightheadedness / fainting
    feeling out of control
    impaired decision making
    loss of concentration
    slowed sense of time

    sounds dangerous, right?

    nah, it’s just anxiety lol

  • I worked out hard then got in suana then I got headache then took a hot shower to relieve the headache then threw up alot and kept sweating after 20 min after shower and dry then took a cold shower I felt a lil better

  • I survived a heat stroke. Lets just say that if u never had one be grateful. The pain is beyond anything i have ever experienced. Your head feels like its about to explode. I was vomitting so much it became like a comedy and I was unable to think coherently or speak.

  • I got mild stroke appears n disappeared within seconds… my nose facing left my mouth in left side n my eye down… n sometimes feeel numb in my left arm n I feel massive pain in my left leg.. now scared of what will happen sooner or later if not treated.. I feel ashamed walkin on street with stroke face…��������������������have been through soo much n long last got stroke sometime can’t breath hmm God help me

  • I’ve almost had a heat stroke in my car multiple times bc I always wear hoodies or any other long sleeved shirts bc of my intense self harm addiction. And just today I was out going for a walk with my gf around the neighborhood and I was getting weaker and weaker with every step I took. My feet and hands were turning red and BURNING. I finally made it back home and as soon as I walk inside, my head started throbbing as if it were a heart beating, my heart rate was high and my whole face was a blood red. I collapsed onto my bed and my head throbbing and headache only got worse. My vision blurred and I was out for about 2 minutes. This all happened 8 hours ago and my head still hurts but only on my left side

  • My uncle had very serious problem termed as Hyperthermia, it is a condition when body temperature is elevated beyond normal due to failed thermoregulation. Excessive dry skin is one of the common sign of this. He used Ayurvedic remedies of Planet Ayurveda and got very effective results. So, to get rid of these problems use “Giloy Capsules & Amalaki Rasayan” by “Planet Ayurveda”. These remedies are really very beneficial.

  • Wouldn’t throwing them in ice water after the extreme heat cause a rapid drop in body temperature which would throw their body in shock which would do more harm than good?

  • Peyton,
    There has been intense winter weather where I am, very cold temperatures, huge piles of snow with sleet, frozen fog, no electricity and consequently no heat for days at a time and nights were spent by candlelight. I have been exercising in the cold because of shoveling the snow from the driveway. Honestly, if I have to shovel snow I would rather do that when the temperature is 80 degrees.

  • My body temperature in the heat stroke can reach to 100 degrees Celsius my sister’s kidney infection reached over 105 degrees Celsius normal body temperature should reach 40 or maybe even to 34 a cold �� usually a run a lot my heart pumps really fast I do get overheated over the winter usually it’s your body that’s heating up earning some steam don’t run too much.

  • i’m surprised i never got a heat stroke, ran 12 miles in 105 degree weather Lol i almost did pass out though, i thought i was going to die. BUT I DIDNT DID I.

  • I’m training for the mines and so working out in long pants and shirts in summer. I can’t sleep after finishing a big work out 6 hours ago. I sat in the sprinkler until I started to shiver. I’m wondering if I got mild heat stroke whatever that means and is causing me to be restless so can’t sleep. Or it could be the half dose Of pre workout but I didn’t stop for 2 hours so I thought would get it out of my system.

  • 2:12 (whenever the temperature is taken in this method and only if babies cry when their temperature is taken rectally, correct me if that’s not the case)
    Babies have left the chat
    (no offence)


  • 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.

  • Another video full of wonderful information! I’m so glad I love water like I do, no issues there for me, even better my little girl guzzles it too!

  • I work very hard out doors all summer long. To stay hydrated I have to drink at least two gallons of water which I usually gulp down during short breaks throughout the day. I mix in two or three scoops of a sports drink, but at the end of the day I still fell dehydrated and my belly hurts Do you have any tips to help my hydrate without the stomach irritation?

  • It’s always important to be constantly hydrated or things like this happen. In 2015, I was cycling in 119 degree farenheit heat for almost 2 hours, I quickly went through 2 gallons of water, still my head was tingling, and I felt the chills, an onset of heat stroke, when I started getting dizzy I pulled into some shade and waited out the heat. I had to wait about an hour until about 540 PM when it was bareable to continue on.

  • I had a heat stroke yesterday, feet and hands shaking and severe tingling getting worse in hands and feet could not get up off the ground, finally a nabor brought over a cold water i downed it and felt a lot better so she got me another one that helped a lot, the paramedics just took my blood pressure it was at 140 for a long time, i don’t have insurance so i had to sigh a paper saying i refused a trip to the hospital they had no idea what my temp was because they didn’t check, they just wanted my name and address so they would know where to send the bill.

  • Put in a tub of ice water? I was taught in nursing school to apply ice packs to the groin and axillary region because cooling them off too quick could lead to seizures

  • Oh shiI just realised. I have suffered from 2 heat strokes. The first time I woke up and started to collapse. I felt so hot, my Mother dragged me in front of our air conditioner at like 2 in the morning and I felt better.

  • had a heatstroke a couple weeks back when I was roughhousing with some siblings of a friend, felt real dizzy, had a ton of blood pumping into my head, and the next thing I knew I passed out. apparently when I lost consciousness I was shaking uncontrollably and moaning alot, and even though i was down for only about 10-15 seconds, I had a really trippy dream that seemed to last around 5 minutes. thankfully I didnt have to do anything like go to the hospital, I just drank a ton of water by a nearby water fountain, friends made sure I was okay for the next hour or so before letting me head home

  • Yeah i got heatstroke once and im only 12
    And i was in school
    I feel dizzy weak and i cant focus
    So i ran to the school infirmary
    A good thing the infirmary has AC

  • I had a sun stroke on a cruise ship once,I had no idea what was happening,all I knew was I needed to puke

    My skin wasn’t very sun repellent

  • every single time i click on a ted-ed video,, i will find a even more interesting one in the suggestion and ends up jumping all the videos HAHA

  • There was a heat wave and I was at the beach most of my body went numb and I got a terrible headache, kind of felt like I had a concussion, did I get a heat stroke?

  • Once I was riding my bike and it was windy outside
    Windy as in trees shaking and it sorta was sprinkling
    5 minutes later my chest was killing me and i was super sweaty
    What happened

  • I’m from a tropical country, and there it is common knowledge that if someone’s out under the sun for a long time, they MUST wet their head fairly often, to avoid a sun/heat/blah-stroke. Specially people with darker hair.
    I moved to a northern country some years ago and I was surprised that nobody knew about this, in fact nobody believed me when I told them I needed to wet my head if we were outside on a walk/hike. At least not until I nearly passed out. But that doesn’t require me doing intensive exercise (heck, if I were at a pool I had to make sure I’d dunk completely underwater every so often to avoid that, even if I was doing nothing but laying around), as long as I’m under the sun for a prolonged amount of time is enough to cause an effect.

  • Thanks so much for this info! You look great by the way! I am the type that needs to work at staying hydrated. The fluid recommendations for exercise are super helpful!

  • Would be very appreciated if this could be shared, sent, or even given a little look over. This is a GoFundMe for my mom and her past + recent medical issues. She has had alot going on with her disorder and sickness and was also deemed disable. This GoFundMe would be helping out her medical bills now and for the future. Many many tests will be ran and continued as they have over the years with the help of this. This is important to me and my family and sharing it on here is a last hope we have. Please share! Everything and anything is appreciated! ❤❤❤
