Men's body is of high intelligent and can change to different weather conditions for running. First, the skin blood vessels start to expand so that the blood inside the body flows over. And then emit the heat to air, this explains why some people skin appears red in hot days.
If these functions are sufficient to maintain a stable body temperature, then other changes will not occur again. But in the condition that temperature continues increase, body will use its potential energy - sweat. In the high temperature, the sweat glands can produce about 3 quarts sweat per hour to relieve the hot weather. Generally speaking, body can keep normal temperature by sweat evaporation.
But it is not always the case. Some people attend strenuous exercise, such as running, is likely to meet special cases. Because he (or she) will produce much more heat compared to rest people. And if the body can not balance heat in normal range, there are 3 cases happened. Generally they are heat cramps, heat exhaustion and heat stroke.
Heat cramps. It will appear in the small calf free muscles, and usually is the signal of problems. Some authorities believe that increased use of salt, salt tablet, or food rich in salt, can prevent heat cramps. However, many others insist more salt is unnecessary. They believed that our diets have enough salt, and they have strong proof: long-distance runners do not take into extra salt will get sweat oozing salt crystals after running. They think that we obviously do not have to add enough salt. I do not eat a lot of salt, and never felt an increase in the need for salt intake is necessary, which is only for reference. I think the question about the salt is the most appropriate answer to each of the experimental results.
Heat exhaustion. This may partly due to less water in body because of too much sweat. Partly is due to of the body's cooling system convey excessive blood to the skin, This is a corresponding reduction in the supply of blood flow to the brain, the results lead to confusion or even loss of consciousness. Therefore, the role of heat exhaustion is like power lines in the circuit device, can often prevent more serious third situation occurs.
Heat stroke. When heat stroke, high body temperature - up to one hundred and ten degrees Fahrenheit is a common phenomenon - the skin is often (but not always) hot, dry. Symptoms are dizziness, vomiting, diarrhea, and confusion.
If you meet some runners get heat cramps, or you get heat cramps, massage can relieve it, and continuously drink half bottle of salt water fours times in an hour will make body chemical balanced. For heat exhaustion, let patients to drink salt water with above method. Lie him down, you may lift the legs, up to 8-12 inches. Cool his body with a damp cloth. If heat stroke, immediately brush with cold water or alcohol, put him into the bathtub that full with cold water to lower the temperature. Immediate treatment is necessary.
