"Lao Zhou, why don't you sweat on such a hot day?" Lao Li and Lao Zhou went to the river to fish. In the evening of summer, the weather was very hot. Lao Li's face was covered with beads of sweat, and his clothes were covered with sweat. All soaked. Looking at Lao Zhou who was not sweating next to him, Lao Li asked curiously.
"I am a person who doesn't sweat much. Although I feel very hot, I just don't like to sweat!" Lao Zhou replied.
"Isn't it said that sweating can detoxify and lose weight? It's not good if you don't sweat, right?" Lao Li said matter-of-factly.
"Then you sweat a lot and you might be weak!" Lao Zhou replied disapprovingly.
The last chat between the two ended unpleasantly by continuing to fish without talking.
Sweating in summer is normal, but we do find that some people don’t like to sweat even in summer, while some people sweat profusely with the slightest movement. So which of these two situations is healthier?
1. The mechanism of human sweating
Human body sweating is mainly used to regulate body temperature. The switch for this regulation is in the hypothalamus. In a cold environment, in order to avoid hypothermia, the hypothalamus will release brown fat , bones Muscles and blood vessels transmit signals to cause them to generate heat, tremble, and contract respectively to increase body temperature; When the ambient temperature is high, the hypothalamus will transmit signals to cause blood vessels to expand and sweat glands to work overtime to accelerate water evaporation. We know Water evaporation is endothermic, so the body temperature will drop during this process. The human body prevents excessive body temperature and maintains the body temperature within the normal range through sweating.
In addition, sweat contains a small amount of potassium, sodium chloride, and other substances. In other words, sweating not only helps the body regulate body temperature, but also maintains the balance of trace elements in the human body and keeps the skin healthy.
So can sweating help you detoxify and lose weight?
The answer is no. Although there are potassium, sodium chloride, urea nitrogen and other substances in the sweat discharged by
, the content is very small, accounting for less than 1%. The rest is all water. It is better to say drainage than sweating and detoxification. The same principle applies to weight loss after sweating a lot. A large amount of water in the body evaporates and is lost, and the weight loss is obvious, but it is not a reduction in fat. If you want to lose weight scientifically, you still have to insist on diet and exercise.
2. Which one is healthier, those who sweat when moving or those who don’t like to sweat?
In fact, everyone's physical constitution is different, and the amount of sweating will also be different, and sweating is also affected by gender, age, genetics, personal physical condition and other factors. If the amount of sweating is not very different from that of ordinary people, it is normal and there is no need to worry too much. Of course, sufficient attention should also be paid to unexplained abnormal excessive sweating, little sweating or even no sweating.
3. Don’t like to sweat or have no sweat, what is the reason?
If you are in a high temperature environment, your body is already very hot, but you should be careful even if you don’t like to sweat. It may be that the sympathetic nerve is damaged. , the sweat glands cannot be stimulated to perspire. It may also be due to skin disease , which causes the sweat glands to be blocked and unable to perspire. It may also be hypothyroidism , that is, hypothyroidism and other problems have occurred.
Therefore, if you sweat abnormally less, you should be more vigilant and go to the hospital for examination and intervention as soon as possible.
4. Common reasons for sweating constantly
Is sweating constantly a sign of physical weakness? Not necessarily. Complex human bodies may also experience physiological sweating due to stimulation by environmental factors and mental factors, such as the following two types.
1. Dietary hyperhidrosis, is mainly manifested by sweating profusely while eating. The reason is that the receptor on the tongue comes into contact with hot and spicy food, which stimulates the brain to perspire. Especially if you eat too fast, you will be more likely to sweat.
2. Psychogenic hyperhidrosis, mainly manifests as excessive perspiration when feeling stressed or fearful. The main reason is that the human body is in a state of tension, fear or excessive excitement. the sympathetic nervous system is also relatively excited, thus stimulating and causing perspiration. increase.
5. If the following abnormal sweating occurs, it may be a sign of serious disease! Pay special attention to
1, sweating accompanied by irritability, large appetite, weight loss and other symptoms. Be careful of hyperthyroidism
Hyperthyroidism is hyperthyroidism. The patient's body's thyroid hormone level is abnormally elevated, causing the body's metabolism to "turn on" The accelerator button is pressed like "plug-in", and the patient will eat more, get hungry quickly, lose weight, be easily agitated, sweat a lot, be afraid of heat, etc.
2. If you experience fatigue, hunger, and rapid heartbeat while sweating, be wary of hypoglycemia
Many people diet excessively in order to lose weight, which can easily lead to hypoglycemia. In addition, some patients with type 2 diabetes excessively pursue the effect of lowering blood sugar and eat too little. Excessive exercise may lead to hypoglycemia.
3. Cold sweats accompanied by chest pain. Rapid heartbeat, be wary of myocardial infarction
If you suddenly break out in cold sweats on the forehead, neck, and soles of hands and feet, accompanied by chest pain and a rapid state of mind, you should be wary of the occurrence of myocardial infarction. The patient When a myocardial infarction occurs, the blood output of the heart will be greatly reduced, causing blood pressure to drop, blood vessels to constrict, and the above abnormalities will occur. If you are a patient with a history of high blood pressure or heart disease, you should be especially careful.
4. Unexplained profuse sweating may be a sign of cancer
Many lymphoma patients experienced unexplained profuse sweating before diagnosis and went to the hospital for examination and were diagnosed with cancer. Clinical findings indicate that this abnormal sweating may indeed be a sign of cancer.
