    I can die from sweating just by forcing my human beyond its limit?

    So don’t run in high humidity, more dangerous than smoking?

    I know some players who fake heat stroke, but they always seem fine after a temperature check.

    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.

    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.

    This happens to me when I skip a meal and then take a hot shower or when I exercise (barely).

  14. J. Lee on November 7, 2019 at 10:02 am

    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?

    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 mom said “DONT TURN ON A/C OR FAN BECAUSE IT WILL INTENSIFY THE SICKNESS” and “YOU HAVE TO SWEAT TO REDUCE THE SICKNESS” but I’m literally dying of heat

  22. Sam Phillips on November 7, 2019 at 10:12 am

    I passed out today from a heat stroke

  23. Anthony olvera on November 7, 2019 at 10:12 am

    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

  24. Kwaivious Sankensa on November 7, 2019 at 10:13 am

    This is wrong. If you cool him or her down too quickly, they can go into shock.

  25. JamesTheFox on November 7, 2019 at 10:13 am

    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

  26. Valrey Peebler on November 7, 2019 at 10:14 am

    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.

    0:42 Everybody do the flop!
    But on a serious note, I had a heatstroke twice. It does NOT feel good >_<

  28. Roland Go on November 7, 2019 at 10:16 am

    These days one could succumb to the heat even without exertion.

    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.

    This is why you need to wear sunscreen in summer and drink plenty of water in summer

  42. Nikita Webber on November 7, 2019 at 10:40 am

    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.

  43. Shea Goff on November 7, 2019 at 10:41 am

    When temperatures get too high the elderly will start to die!!! Anyone who gets that reference I love you!!!

    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.

  50. Lowri on November 7, 2019 at 10:47 am
