No matter what kind of work you do, don't forget to do physical work. Even if it is working on the computer, don't let us think that we are working. It is only through physical exertion that sweat comes out which keeps the body fresh.

Exercising first thing in the morning flushes out excess sweat and should be a regular part of a man's routine. Only then are the waste products in the skin areas of the body excreted with sweat, so the sweat excreted through physical exertion is beneficial to the body.

 It is better to drink water during physical activity and before exercise, and it is better not to drink water while resting or sleeping. If you drink too much water while your body is at rest, your kidneys will only work harder and lose strength.

Our body can be compared to a permanent stove where our body burns the food we eat as fuel. In this practice, our body needs more than 2200 calories daily. This heat is very less but this heat is enough to evaporate the water.

Thus, what happens to the heat generated in our body, if there is no system in our body to control heat, our body will be exposed to extreme temperatures. Our average body temperature is 98.64 degrees Fahrenheit.

Sweating is very important for keeping the body at a moderate temperature. The control of keeping the body at a uniform temperature is in the brain.

If our body temperature drops due to some reason, some parts of the brain immediately activate and increase the temperature in the body through some glands. Similarly, if the temperature increases, brain activity will reduce the temperature because keeping the body temperature equal is one of the healthiest things.

Each of our human body has about 20 lakh sweat glands located on the surface of the skin. At the same time, these are not equally distributed in all parts of the body. For example, we have more sweat glands on our palms and feet, but fewer sweat glands on our backs.

Different amounts of sebum are secreted from these sweat glands. The sweats leave the body according to its movement. Due to some diseases, the nerves in some parts of the body become inactive, and sweat stops coming out of these parts.

Sweat consists of 99% water and one per cent sodium chloride. It is only when we sweat that our body gets rid of unnecessary salts. It comes out only during physical exertion, so daily physical exertion is very important. Sweating through physical exertion keeps the body fresh and healthy.
