What should I do if I sweat often? The weather is not hot, it will sweat a lot!

Sweat gland of the body is a kind of secretory gland distributed in the dermis of the skin, and there is a long catheter to guide secretion (sweat) to the surface of the skin. Sweat glands are mostly distributed in the epidermis of our body, especially in armpits, soles of feet, palms and foreheads. Generally speaking, healthy people will increase the secretion of sweat glands when exercising or encountering high temperature, which is a physiological function of lowering the rising body temperature. Therefore, obese people sweat more easily than thin people, not because the former has a large body surface area, but because obese people are overweight and their body temperature tends to rise. In order to reduce excessive body temperature, it must be adjusted by sweating more. In addition to the above reasons, those who usually do not sweat but sweat a lot may have problems with sweat glands. Local hyperhidrosis may be sympathetic nerve injury or abnormal reaction, and the secretion of choline acetate increases, resulting in excessive sweat secretion by eccrine glands. Systemic hyperhidrosis can be an abnormal physiological reaction, symptoms caused by some diseases such as hyperthyroidism, diabetes and other endocrine diseases, and also caused by hypertension, menopause and the role of adrenal cortical hormones. In addition, taking cold medicine to reduce fever and shock may also cause a lot of sweating. When the brain is anemic, the blood flow in the brain is blocked and the thermoregulatory center is stimulated, so people will sweat more. Children are also prone to sweating because of their size. Hyperhidrosis caused by mental depression Another type of hyperhidrosis is called local hyperhidrosis, such as soles of feet, armpits, forehead and nasal tip. And it is easy to sweat, such as sweaty palms when flying or driving; When you speak in public, your face will sweat, which mostly happens when you are depressed or moved. In addition, there is sweating on one side of the body. Hemiplegic patients will sweat more on the unconscious side; Trauma, swelling and inflammation of cranial nervous system can also cause unilateral hyperhidrosis due to stimulation of sympathetic nerve. Hyperhidrosis includes generalized hyperhidrosis and localized hyperhidrosis. Systemic hyperhidrosis often occurs with moist skin surface and paroxysmal sweating. Local hyperhidrosis is common in palms, soles and armpits, followed by nasal tip, forehead and genitals. , and often occurs in teenagers. Patients are often accompanied by peripheral blood circulation dysfunction, such as wet and cold skin of hands and feet, blue or pale skin, frostbite and so on. Foot hyperhidrosis is caused by poor evaporation of sweat, which makes the plantar epidermis white, often accompanied by foot odor. When sweating in armpit and vulva, it is easy to cause erythema, folliculitis and boils because the skin in this area is thin and tender and often wet. 1, avoid nervousness and emotionalism. Those with mental mood can take oryzanol, bromide and diazepam orally. 2, anticholinergic drugs such as atropine, belladonna, propofol, etc. , has a temporary effect. When the dosage of reducing sweat secretion is reached, patients will have obvious side effects such as dry mouth, skin flushing and palpitation. 3. External astringents can be applied with 10% glutaraldehyde solution and 2%-4% formaldehyde solution. People who sweat too much under their arms can use 20% aluminum chloride ethanol solution for external use. Before taking the medicine, dry the armpit and apply it externally every night before going to bed for 7 days. Patients with palmoplantar hyperhidrosis can also be soaked in 5% alum solution or compound copper sulfate solution; Qin Ying, with sweaty feet, put on socks and shoes with good air permeability and water absorption. 4, iontophoresis with tap water and direct current as iontophoresis is suitable for hyperhidrosis. In addition to the above methods, most of the current methods for treating hyperhidrosis are aimed at the sympathetic nervous system, such as surgical ligation of the sympathetic nerve to eliminate the regulating function of the sympathetic nerve to sweat glands, so as to achieve the effect of reducing sweating.
