Why do you sweat so much? Even if the weather is not hot, I will sweat a lot!

The body's sweat glands are secretory glands distributed in the dermis of the skin. They have long ducts that lead secretions (sweat) to the surface of the skin. Sweat glands are mostly distributed on the surface of our body, especially in the armpits, soles of feet, palms, and forehead. Generally healthy people will increase the secretion of sweat glands when exercising or encountering high temperatures. This is a physiological function to reduce the rising body temperature. Therefore, obese people tend to sweat more than thin people. This is not due to the larger body surface area of ​​the former, but because obese people have a higher weight and their body temperature rises easily. In order to lower the excessively high body temperature, it must be adjusted by perspiration. In addition to the above reasons, if you sweat a lot when you don't normally sweat, there may be a problem with the sweat glands. Local hyperhidrosis can be due to sympathetic nerve damage or abnormal reactions, increased secretion of choline acetate, resulting in excessive secretion of eccrine sweat glands. A lot of sweat. Systemic hyperhidrosis can be an abnormal physiological response, or a symptom caused by certain diseases such as hyperthyroidism, diabetes, and other endocrine diseases. It can also be caused by hypertension, menopause, and the effects of adrenocortical hormones, etc. This symptom occurs. In addition, taking cold medicine to reduce fever and shock may also cause profuse sweating. When there is cerebral anemia, the blood flow in the brain is blocked, the temperature regulation center is stimulated, and sweating occurs more. Young children are also prone to sweating due to their body shape. Hyperhidrosis caused by mental depression. Another type of hyperhidrosis is called localized hyperhidrosis. It is easy to sweat in places such as the soles of the feet, armpits, forehead, tip of the nose, etc., such as when flying, driving, or with sweaty palms; among the general public, Sweat drips from your face when you talk in front of you. This mostly happens when you are mentally depressed or moved. In addition, there are also cases of one-sided sweating of the body. Patients with hemiplegia will sweat excessively on the unconscious side; and those with trauma, swelling, or inflammation in the cranial nervous system may also suffer from one-sided hyperhidrosis due to stimulation of the sympathetic nerves. . There are two types of hyperhidrosis: systemic and localized hyperhidrosis. People with generalized hyperhidrosis often have a moist skin surface and experience paroxysmal sweating. Local hyperhidrosis is common on the palms, soles, armpits, followed by the tip of the nose, forehead, genitals, etc. It usually occurs in teenagers. Patients are often accompanied by peripheral blood circulation dysfunction, such as clammy, blue or pale skin on the hands and feet, and prone to chilblains. wait. Hyperhidrosis of the feet is due to poor evaporation of sweat, causing the epidermis of the soles to become soaked and white, often accompanied by foot odor. When there is excessive sweating in the armpits and pubic area, because the skin in this area is thin and tender, and is often moistened and rubbed, it is prone to intertrigo erythema, accompanied by folliculitis, boils, etc. 1. Be nervous and avoid nervousness and excitement. Oryzanol, bromide, diazepam, etc. can be taken orally for those with mental illness. 2. Anticholinergic drugs such as atropine, belladonna, prubencin, etc., taken orally, have temporary effects. When the dose that reduces sweat secretion is reached, patients will experience obvious side effects such as dry mouth, skin flushing, and heart palpitations. 3. For topical astringent drugs, 10% glutaraldehyde solution or 2%-4% formaldehyde solution can be applied externally. People with excessive sweating in the armpits can apply 20% aluminum chloride ethanol solution externally. The armpits should be dried before use and applied externally before going to bed every night for 7 consecutive days. Patients with palmoplantar hyperhidrosis can also be soaked in 5% alum solution or compound copper sulfate solution; those with excessive palmar and plantar sweating should change socks frequently and wear shoes with good breathability and water absorption. 4. Iontophoresis: Iontophoresis using tap water and direct current is suitable for hyperhidrosis.

In addition to the above methods, most of the current treatments for hyperhidrosis are targeted at the sympathetic nervous system, such as surgical operations, ligating the sympathetic nerves, and eliminating the regulatory function of the sympathetic nerves on sweat glands to achieve the effect of reducing sweating
