Sunstroke is a life threatening condition caused by overexposure to extreme heat. Also sometimes called heatstroke, this condition occurs when the body’s heat control system fails and it cannot lose the excessive heat. High temperatures can cause the body’s major organs to fail.

There are a large variety of symptoms present with the onset of sunstroke. In the early stages, the skin will become both hot and dry. Sweating usually stops, and breathing becomes rapid enough to bring on hyperventilation.

The body’s temperature, along with the pulse, will begin to rise rapidly. Other symptoms include muscle cramps and headaches. There may also be some mental and verbal confusion. Speech may be unintelligible or incoherent, and violent behavior may appear.

As sunstroke becomes more severe, the sufferer may be prone to hallucinations. The body’s temperature will rise rapidly, and convulsions may occur. Finally, the sufferer will lose consciousness.

The cause of sunstroke is usually lengthy exposure to high temperatures. It can also be caused by heat exhaustion. People who work outside are susceptible, as are people who exercise for long periods of time without proper fluid intake.

Sunstroke can happen to anyone, but older people and children are more susceptible. If the body has had or is going through an illness, then sunstroke may occur more easily. Also, wearing clothes that are not suitable for high temperatures can contribute to symptoms.

Certain medications can also contribute to the onset of sunstroke. Antidepressants, beta blockers and diuretics may have an adverse affect and interfere with the body’s heat control system. Sudden cramps and muscle spasm are also symptoms.

If sunstroke occurs, a doctor or medical help should be sought immediately. Blood pressure and body temperature tests will be taken in order to diagnose the condition. Urine and blood samples may also be taken.

Depending on the extremity of the condition, a stay in the hospital may be required. Body temperature will need to be lowered as soon as possible. Fluids and salt will need to be replaced, usually by an intravenous (IV) drip. A period of observation will also be necessary to monitor any temperature changes and to look for any complications that may occur.

I laid in the sun most of the day yesterday and the day before I went to the beach. The temp has been 26*c but I've been feeling sick all the time and have loss of appetite. I also feel drained and have diarrhea. Is this heatstroke or heat exhaustion? Please help someone?

I was in the sun a few days ago for about two hours straight in florida tanning, and I got a big rash on both my legs and they are like little red dots. I guess they're like a sun rash. Now this morning I woke and my sweat was just running off of me and when I got up to go throw up, I got really, really weak. Also, I have diarrhea with it, and I'm really tired.

I am a resident of a more humid but not so hot climate. My job requirements have brought me to one of the hottest places in the country. Here, I have started getting a few of the symptoms of sunstroke but want to confirm whether it's actually sunstroke or not.

So my question is, "Is there something else that resembles a sunstroke, but is not as severe?"

P.S. I am having headache, a light feverish feeling, muscle pain in my right foot, giddiness. I have suffered from whatever this is two times in the past two years, hence I am more concerned now.

@anon196343: Five and a half hours on the beach? No, I doubt you have sunstroke. You have "cooked like a lobster" syndrome, and the only cure for it is time.

You're hurting because your skin is burned and inflamed. I recommend you get some aloe vera gel and put it in the fridge, then when it's cold, rub it on your skin. Also, try taking ibuprofen, which is an anti-inflammatory, drink lots of water and stay out of the sun to avoid making bad matters worse. If you start feeling really bad, your skin starts raising blisters or if you run a fever, see a doctor.

I guess most of us get a bad sunburn at least once in our lives, and it sounds like you've got a real doozy. I hope you're not on vacation, because the next couple of days aren't going to be fun.

Sorry to sound like a prophet of doom, but I've been there. Next time, use a good sunblock with at least 30 spf, reapply every 45 to 60 minutes, wear sunglasses and a hat. A sunburned scalp is a particularly fun kind of torture -- especially when it starts *peeling*!

I am 15 and spent five and a half hours in the sun on the beach yesterday. Last night my skin had turned bright red and today my skin is burning, I have been having headaches, I am extremely tired and when I move it hurts but I am unsure whether this is because of the burns or just when I move in general. I am wondering if this is sunstroke or something else that is wrong with me?

My son is 13 so it would seem he is deemed old enough to take responsibility for himself in the sun, however he was out in the sun on a school trip for four and a half hours.

He put sunblock on in the morning but they went swimming then played in the sand and without re applying sunblock, no hat or shirt. His skin was red (he's never been burnt before) and he vomited and had diarrhea this evening. I feel this is a health and safety issue and the school has a responsibility by making sure children slip, slop and slap

Well I'm 14 and I spent a 12 hour day on Saturday at my local baseball field. It was around 30• C, I raked the whole large diamond (field) twice all by myself, worked in the canteen most of the time and had to coach my U7's team. I then had headaches, bad cramps and my eyes were so sore, I'm still feeling it today. Do you think I might have sunstroke?

i am on holiday in morocco with my parents and friend jasmine. jasmine and i went out surfing today and jasmine has some symptoms of sunstroke.

She has hallucinated smells of olives and cooking, she has become very lethargic and drowsy, she has suffered violent sickness and diarrhea, she has been suffering hot and cold flushes, and she has mild muscle spasms in her left thigh.

could this be sunstroke?

we also have suspicions that these symptoms could be the result of swallowing too much sea water. Any help working out what is the matter?

I believe my 10 year old daughter may have caught a touch of sunstroke on Saturday. She was in the hot sun for over four hours and she did tell me she knew she wasn't drinking a lot of water. She started running a fever Sunday morning, vomited two times, and was very lethargic. She also was very tired and she had headache. Today, Monday, she feels almost 100 percent better.

I see a pattern, because about two weeks ago, she was in the sun all day and the very same thing happened. I made her drink tons of water Sunday all day. She complained that she was tired of going to the bathroom but to me as long as she was going we were on the road to recovery. Drink lots of water when you are in the hot sun.

I see the pattern from the first time to this time and she is possibly prone to this now. We will be talking to the doctor to find out more information. --Concerned Mom, Vernon Hills, IL

I have suffered for four days with sun stroke without really knowing what it was. Today I stayed in bed with exhaustion cramps, headache, feeling hot but dry and very depressed. Pain killers didn't work. It wasn't until 5 p.m. that i had food and drink which helped a bit.

Later I let the cold shower run over my head until I couldn't feel the cold any longer, and that felt much better. But I still feel a bit bad. Any ideas on what to do now? I really don't want an other day of this feeling. Many thanks.

My daughter of six went on a school trip yesterday to a local country park (Rufford Park -- very nice). She wore a hat all day and they could only take their normal school water bottle.

She is now off today with what seems to be sunstroke and it is not pretty. The school did not take any extra water with them. Totally outrageous. The school has felt my wrath over not taking enough water and keeping them out all day in the sweltering heat.

yesterday i was in the sun all day working. it was seriously hot. when i finished, i went to the gym with a partner and i couldn't even work out. it was almost as if i couldn't be bothered, so i was told to just sit in the swimming pool for a little while to cool down, that i was in the sun too much without protection.

i thought i would be fine and i didn't feel too bad so i went to the pub with my partner and couldn't bear it anymore. i went completely the wrong way: getting cold and shivering. i couldn't even have a sip of my beer, then i started getting a watery mouth and feeling as if i were going to be sick, so i went to the toilet but i wasn't sick. i had the runs after that.

i had to go home feeling really light-headed and jittery with a headache and i was throwing up all over the place. the next day i wasn't so bad. just make sure you drink plenty of water and eat some toast.

"I think I have sunstroke...what do I do now?" Use you bloody brain and go and see a doctor or go to the hospital! I'm pretty sure if you have time to search the web to see if you have the symptoms of sunstroke you wouldn't have the time to browse the web! Come on just get some common sense please!

I had sunstroke when i was eight, and all i remember was one minute i was happy as larry in a paddling pool and the next minute bang! My muscles cramped, my eyesight went completely red, i sweated like i can't describe, felt like i was being spun around at 30mph and fainted.

Yes, once you're exposed, you are more vulnerable to sun stroke. also i had swelling i looked like the elephant man. it's horrible and the pain is unbearable. you just want water 24/7.

i wouldn't wish it on anyone. I'm 21 now and I've had it six times since my first time at eight years old.

can one heat stroke put you at risk for future sunstrokes or heat strokes? my father in law suffered one several years ago, and now is extremely susceptible to the heat. my mom also had one where she stopped sweating completely. she got very weak, and rested and drank fluids, then suddenly became drenched with sweat. fortunately, she recovered after that without having to make a trip to the hospital.
