2. Physiological causes of armpit sweating
1.Sweat gland distribution characteristics: There are about 2 to 4 million sweat glands in the human body, among which the armpits are a dense area of apocrine sweat glands, containing about 600 sweat glands per square centimeter, which is 10 times that of other parts.
2.temperature regulation mechanism: When the ambient temperature exceeds 31°C (generally above 35°C in summer), the hypothalamus stimulates the secretion of sweat glands through the sympathetic nerve. The fold structure of the armpits has low heat dissipation efficiency and is more likely to accumulate sweat.
