Body temperature during exercise

Heat stroke is a concern primarily during hot weather, but in the relatively cold ambient temperature of 50 F, healthy marathon runners can have body temperatures of up to 103.8 F. Weightlifters often have temperatures of 101 F during workouts in a warm gym. A runner who was still conscious reportedly developed a temperature of 107.8 F after finishing a marathon, but most people cannot tolerate such high temperatures.

You suffer from heat stroke when your body temperature rises so high that it cooks your brain and you pass out. This is particularly likely to happen when you exercise, especially in hot climates, because food is converted to energy through a series of chemical reactions, each of which releases heat. The sum of the reactions converts more than 80 percent of the energy into heat, while less than 20 percent is actually used to drive the muscles. That means the more you exercise, the higher your temperature can rise, and your body has to work very hard to keep it from overheating. During exercise, your heart must not only work harder to pump oxygen from the blood in the lungs to the muscles, but it must also pump heat in the blood from the muscles to the skin where it sweats and evaporates to cool off infrared temperature reader.

Several factors increase our chances of developing heat stroke, such as when the outside temperature and humidity are high, you are not fit, you are taking certain medications, or you are sick or dehydrated. Aspirin does not prevent your temperature from increasing during exercise because aspirin reduces fever by making you sweat and when your body temperature increases during exercise, you sweat and aspirin does not make you sweat more.

To protect yourself from heat stroke when you exercise, start slowly and gradually increase your pace. This gives your body time to circulate heat to the skin, where the heat can dissipate. Drink fluids long before you are thirsty. Once you are thirsty, you are already dehydrated and have lost at least 2 pounds of fluids. Drink what you like best at least every 15 minutes and know the symptoms of increased body temperature. When his temperature rises above 102, his muscle often starts to burn, when his temperature is above 104, he is usually short of breath, and when his temperature rises above 105, he will often have signs of brain anguish, such as headache, blurred vision, ringing in the ears, dizziness, nausea, and fainting.
