But you sweat a lot, so you should pay attention to supplement salt and water after exercise.
There are two kinds of sweat glands in human skin: one is called eccrine gland, which is distributed all over the body; The other is called apocrine gland, which is only located in armpit, around nipple, vulva and anus. In childhood, apocrine glands do not develop and do not produce corresponding secretions. During adolescence, apocrine glands begin to develop rapidly, so they often sweat and sometimes sweat. Some people may still have body odor. In old age, people's sweat gland secretion function decreases, and sweat will also decrease accordingly.
About the same time you start to grow a beard, you may notice that hair grows on your armpits. Occasionally, some boys have armpit hair before they start to grow a mustache, even before pubic hair appears. But for most boys, beard and armpit hair appear almost at the same time.
Once you start to grow armpit hair, even before that, you will notice that there is much more sweat under your armpit, and the sweat now has a different taste from the sweat when you were a child. You may also notice that other parts of the body, such as genitals and feet, also have different smells. Or you may notice that your hands are love sweating and often sticky. These changes are the result of testosterone secreted by testis acting on sweat glands in these parts of the body.
This is a natural and healthy part of physical development, but some young people are still worried about the increase of these smells and sweating. Their worries are not surprising. But if you have a normal diet and are healthy, then your smell may not be so annoying. Taking a bath or shower regularly and wearing newly washed clothes will keep your body odor pure and fresh. If you sweat a lot, which bothers you, you may find it helpful to wear cotton undershirts and shorts. Cotton fabrics absorb sweat more than synthetic fabrics. It is also helpful to wear coats and trousers sewn with cotton or woolen cloth or other natural fiber products.
People sweat more when they are nervous. In adolescence, this trend is more obvious. When many teenagers are nervous, their hands are always sticky, or they suddenly sweat all over. This is normal. Generally, in the twenties, this phenomenon will decrease. If you have this problem, it is useful to remember that this is a normal phenomenon. Sometimes just admitting to myself, "Yes, I'm really too nervous now (or too embarrassed or too nervous)" will also help me relax and reduce sweating.
1, should be a small number of times, each time 100 ml is appropriate. Drinking too much water, a lot of water enters the blood, which increases the blood volume, increases the burden on the heart, reduces the osmotic pressure of the human body, affects water metabolism and slows down the water absorption rate. Moreover, drinking too much and excreting too much make a lot of salt lose, which destroys the salt balance in the blood, easily increases the fatigue of the body and causes muscle spasm.
2. Water can be replenished by itself. Generally, water drinks can be prepared according to the following formula before exercise: every 1000ml of cold boiled water, 4g of salt, 0/00g of glucose 150ml of orange juice/kloc-0. This not only supplements water, but also supplements salt, glucose and vitamins, so that the metabolism of water and salt in the body is balanced.
3, it is not advisable to drink cold drinks during strenuous exercise or after exercise, so that the gastrointestinal blood vessels are stimulated by cold, causing sudden contraction of blood vessels, causing stomach cramps and stomach pains, which will lead to chronic stomach diseases over time; Furthermore, during strenuous exercise, the capillaries in the throat dilate and are suddenly stimulated by cold, which is easy to cause throat inflammation and cough and gargle symptoms.
