What is the reason why children sweat more when exercising?
There are physiological and pathological differences in children sweating. For example, sweating and strenuous exercise in hot weather are all physiological phenomena.
There are two most common types of sweating caused by pathological reasons: one is night sweats, which appear unconsciously when sleeping at night. The other is spontaneous sweating, which occurs during the day and does not sweat spontaneously due to labor, thick clothes or heat, or after a little exercise.
The main cause of spontaneous sweating is physical weakness or after a serious illness. Chinese medicine thinks so? Is lung qi deficiency weak? What should be the basis caused by treatment? Reinforce lung and qi, consolidate exterior and nourish yin? For principle. You can take Buzhong Yiqi Pill and Shengmai Drink to nourish the earth and produce gold, replenish qi and astringe sweat, or chew American ginseng and ginseng, or you can add and subtract Shengmai Powder and Yupingfeng Pill.
Sweat gland secretion is closely related to exercise intensity: the general rule is that the greater the exercise intensity, the more perspiration. Because with the increase of exercise intensity, muscle activity is more intense and more calories are produced. In order to maintain a normal body temperature, the human body must increase the amount of perspiration to emit excess heat. Therefore, the greater the intensity of exercise, the more perspiration is bound to occur.
The amount of sweat is first related to individual differences: as we all know, sweat comes from the secretion of sweat glands, and the number of sweat glands is extremely large. Millions of sweat glands can be roughly divided into two categories: one is eccrine glands, which are widely distributed under the skin of the whole body, with an average of about 300 per square centimeter and about 2.3 million all over the body. When exercise or the temperature of the external environment rises, the human body mainly relies on this sweat gland to sweat, which physiologists call warm sweat. The other is apocrine gland, which is distributed under the skin of armpit, nipple and vulva. When people are frightened, excited or humiliated, it is mainly this gland that sweats, which physiologists call nervous sweating. Physiological studies have found that there are not only gender differences but also individual differences in the number of small glands and large glands. Therefore, under the same conditions, some people sweat more and some people sweat less. In addition, individual differences are also reflected in the number of body fluids. Some people have more body fluids and sweat more when exercising; Some people have less body fluids and sweat less when exercising. The amount of body fluids often depends on the fat content in the body, because there is less water in adipose tissue, so fat people have less body fluids than thin people. Although fat people sweat a lot during exercise, their tolerance to water loss is relatively poor. In other words, if the exercise time is not long, fat people will get tired prematurely because of the disorder of water and salt metabolism. Whether to drink water before exercise also affects body fluids. If you drink plenty of water before exercise, you will also increase sweating due to the increase of body fluids.
So the amount of sweating varies from person to person, so don't worry.
How good is it to sweat when exercising?
The benefits of sweating
Sweating organs of human body are sweat glands in skin, which are well developed and belong to human body? Radiator? If you don't sweat, your body temperature will not be discharged, and your body temperature will rise; Sweating or something? Water and salt regulator? In addition to containing 98-99% water, it also contains a small amount of salt, urea, lactic acid and fatty acid, so sweating helps the kidneys to excrete waste and regulate electrolyte and acid-base balance. Weakly acidic substances produced by sweat decomposition have certain antibacterial effect. People who don't sweat have slow skin metabolism, and some wastes are difficult to eliminate.
How much sweat do you have?
The higher the temperature, the greater the amount of sweating, needless to say. It is normal to sweat a lot during exercise. In addition to the ambient temperature, the amount of perspiration depends more on one's own physique. Some people are naturally sweaty, and some people can see obvious sweat when sweating; Some people can't see the sweat, but they can feel the heat radiating from them. In addition, some people have more body fluids and sweat more; Some people have little body fluid and sweat. Sweating is also related to drinking water. If you drink plenty of water before activities, you will increase your sweating due to the increase of body fluids. How much you sweat during exercise is not necessarily related to the exercise effect, but directly related to your physical fitness. Therefore, we should not pay too much attention to the amount of sweat during training, or take it as a measure of exercise intensity. Fitness instructors should ask members more about their physical feelings, observe their breathing frequency and test their heart rate during the teaching process, so as to better understand their exercise intensity. The amount of sweat of different members varies greatly. Only when the same person is doing the same amount of exercise, the less sweating, the better, indicating that his training level has improved and his body's self-regulation ability has been enhanced.
Hydrate after sweating.
You can shed some sweat and lose some weight during exercise, but you should also be careful, at this time, the water and trace elements in your body are quietly losing. During exercise and every 15 minute to half an hour after exercise, you should add some water. Once you are seriously short of water, feel weak and want to vomit, you can add half a teaspoon of salt to your drinking water to supplement the lost salt. No water? Bull drink? I came many times and drank less. The temperature of drinking water should be close to body temperature. Drinking cold drinks after strenuous exercise is easy to stimulate the stomach. The main electrolytes in sweat are sodium ions and chloride ions, and a small amount of potassium and calcium. Under long-term exercise, the lost sweat contains the most sodium, and the loss of sodium ions and chloride ions can not adjust the physiological changes such as body fluids and temperature in time. At this time, supplementing water may not be enough to cope with the loss of electrolyte. Blindly drinking too much boiled water will dilute the electrolyte in the blood, leading to hyponatremia. Sports drinks can not only replenish water, but also contain sodium, potassium, chlorine plasma and glucose, and can also replenish lost electrolytes. For a small part of sweating loss, the electrolyte stored in the body will be automatically released into the blood to maintain the electrolyte in the blood constant, so it is only necessary to replenish water after short-term exercise or sweating. In addition to sports drinks containing electrolytes, ordinary fruits and juices are also foods with high sugar content, which is also very helpful for the body to recover and maintain electrolyte levels after exercise, and can also make you not insist on sports drinks after sweating.
Prevent excessive sweating and dehydration.
Although sweating is a physiological regulation, excessive sweating and insufficient fluid replacement will lead to dehydration and affect health. Mild sweating produces thirst, oliguria, fatigue and muscle spasm, and in severe cases, it causes heatstroke, high temperature and even life-threatening. Long-term indoor activities in summer, due to poor air circulation, even under air conditioning conditions, the human body will lose a lot of body fluids through evaporation, breathing, urination and other inconspicuous sweating methods, resulting in dehydration phenomena such as fatigue and thirst. How to determine the loss of body fluids? How to replenish lost body fluids? Generally, the method of weighing is used, that is, weighing before and after exercise, and the difference in weight is the amount of sweat during exercise. Rehydration is based on the weight lost that day. For every 65,438 0 kg weight loss, at least 65,438 0,500 ml (65,438 0.5 L) of liquid should be added to correct dehydration.
