3 Running Exercise Problems in Heat Days

When the temperature is high, body will have the ability to balance body temperature and make running go smoothly. 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. In most cases; the evaporation of sweat is enough to keep body temperature within normal range.But it is not always the case. A person, such as runners, engaged in intense exercise in hot climates is easier to encounter special problems. Because they produce more heat than standstill people. If the body's temperature control mechanism can not bring the temperature down low enough, three situations can occur. Generally they are heat cramps, heat exhaustion and heat stroke.Heat cramps. This will occur to the small calf, and often the problem occurs first signal. 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. Some runners even do not add salt to meals, after finishing a long race, they have the appearance of skin sweat oozing salt crystals. 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. Part of this happening is due to reduction of body fluids (sweat results). 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 see a runner or you are troubled by heat cramps, the role of massage can play a relieve role, in addition, drink a half glass of salt water every fifteen minutes continuously for about an hour, you can restore the body's chemical balance. To heat exhaustion, you may let him drink some salt water. To enable patients lie down, raise their feet eight to twelve inches. Cool his body with a damp cloth. If it is heat stroke, you would wipe body with cold water or alcohol, put him into the bathtub that full with cold water to lower the temperature. Immediate cure is key.
