What causes sweating on the back of your hands?

Human hands are mainly divided into the palm and the back of the hand. Most people only feel their palms sweating, such as when they are too nervous or the weather is too hot, but a small number of people find that the back of their hands also sweat. The problem of sweating on the back of the hands is obviously very different from the problem of sweating on the palms. Therefore, patients with sweating on the back of the hands should understand the causes of sweating on the back of the hands.

1. Reason 1: The cause of sweating on the back of the hands is generally due to excessive tension of the sympathetic nerves, such as tension, excitement, stress or high temperatures in summer, which causes abnormal increase in sweating on the palms.

2. Reason 2: Most people start sweating on the back of their hands since childhood, and the condition becomes more serious during adolescence. Patients with symptoms of sweating on the back of their hands are generally healthy and normal except for the sweating of their hands.

3. Reason three: Sweating on the back of hands may also be caused by autonomic nervous system disorder, which also has certain genetic factors. You can take some oryzanol and vitamin B1. In severe cases, you can take 654-2 tablets.

Note:

In daily life, you should pay attention to your diet, avoid eating spicy foods, avoid being impatient, and exercise moderately.

Sweating and health

98-99% of a drop of sweat is mainly water, with a specific gravity of about 1.002-1.003 and a pH value of 4.2-7.5. NaCl is about 300 mg/100 ml. 1-2% is a small amount of urea, lactic acid, fatty acid, etc.

Sweat is a fluid secreted by sweat glands. Sweating caused by heat stimulation due to increased external temperature or increased heat production in the body is called perceived sweating. At this time, the sweating area is widely distributed, covering the skin of all parts of the body, especially the forehead, neck, front and back of the trunk, waist, back of the hands and forearms; followed by the neck, sides of the trunk and most of the limbs; again the inner side of the thigh and armpits; the least is the palms and feet. Mental stress can also cause sweating. The sweating centers are distributed in various parts of the central nervous system. A normal person evaporates about 600 to 700 ml of water unconsciously within 24 hours.

Sweating can be divided into active and passive types. The so-called passive sweating refers to sweating caused by hot weather and irritable mood. This way of sweating is not good for the human body. On the contrary, sweating caused by active movement of the human body is called active sweating. It helps to maintain the body's temperature, dissipate heat, and is beneficial to people's physical and mental health.

The function of sweat is to regulate body temperature. If you think about it carefully, the human body is really like a precision machine. If you don't sweat, you're out of luck. When you exercise, your blood circulation speeds up, your body temperature rises and you sweat, which lowers your body temperature. When it gets cold, your sweat glands and pores contract, and you stop sweating, which prevents your body temperature from dissipating.

Sweat is the "air conditioner" of our body. According to traditional Chinese medicine, we sweat in the summer, and sweating is a form of detoxification. There are two ways for people to detoxify: one is urination, and the other is sweating. Sweating is the most effective way to detoxify. Summer is the only season in the year when one can sweat naturally. This is beneficial to the body's metabolism, meridian balance and the health of the immune system. If you hold back on sweating for a long time, your skin will stop breathing, and eventually it will cause disorders in the body's metabolic system and transfer the skin's detoxification function to the kidneys and liver.

Therefore, if you often do not sweat in your daily life, you should pay attention to it. Disease prevention and control is very important.
