What is the reason for sweating at the tip of nose?

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. So obese people tend to sweat more than thin people, but it is not.

Because the former has a large body surface area, obese people have a high weight 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, a symptom caused by some diseases such as hyperthyroidism, diabetes and other endocrine diseases, or the effect of hypertension, menopause and accessory renal cortical hormone.

This symptom may occur.
