When people have sunstroke, their body temperature will be high, up to one hundred and ten degrees Fahrenheit, but at this time, it seems to be a common phenomenon. Skin will be hot and dry most of the time, but it will change sometimes. There are also other symptoms of sunstroke, such as dizziness, vomit, diarrhea, and unconsciousness. Find a doctor and let him give an immediate medical treatment to people who have sunstroke is very necessary. If you see a runner who have hot spasms, you can give him a message, because this behavior can play a remission role. Furthermore, balance of body chemistry will be restored if you can drink half a glass of salt water every fifteen minutes and keep on for an hour.

For heat exhaustion, we can allow patients to drink salt water as the above method. To enable patients to lie down, rise their feet up to eight to twelve inches. Loosen his clothes, use wet cloth and fan to cool his body. If you had sunstroke, you must immediately brush your body with cold water or alcohol, or put the patient into the tub, which is filled with cold water to lower his body temperature. Under this circumstance, an instant remedy is indispensable. The second problem that related to heat is dehydration. This phenomenon is a dangerous thing, because the body largely relies on water to maintain its condition. Many of its chemical reactions have to happen in water. Water can help to transport substances, which are needed by different parts of the body. Water is a crucial factor if you want to keep in usual temperature in hot weather.

Do not worry about the phenomenon of dehydration under normal condition if your exercise time is not long. However, if the exercise continues, it can result in water shortage in blood, some substances' dense disorders in bloods and cells and heat exhaustion.

But you can take several measures to reduce the possibility of occurrence of the above symptoms. First, wait until you are able to exercise in the hot climate and then take an intense workout. If you want to adapt to the hot climate, you have to spend about seven to ten days in doing so. Stroke rate will reduce, secretion of sweat will increase and sweating time will also be faster during this period. If you have time to increase your exercise intensity everyday, it will be the most effective way to adapt to heat. After you used to run in hot weather, this adaptation to climate can be maintained about two weeks.

We should drink more if we do exercise in winter. I used to hold the opinion that we should not drink water if we do exercise. It has been showed by reports that athletes, including running athletes can best play their body functions if they can drink water at will. The efficiency will lower fifteen percent if you make weight drops five percent for water shortage. One can bear weight loss comfortably, but the maximum limit is six percent. For the sake of making up for the loss of body fluids beforehand, and some authorities also recommend drinking water before taking exercise. David Coe Steele, a science researcher, named it the camel water, which is more lively, but without too much elegance. The reason is that the speed of our bodies' absorbability of liquid is half equal to the speed of sweating in hot weather.
