Why do girls sweat a lot under their armpits?

Girls pay great attention to their image. However, in daily life, many girls have the problem of excessive sweating under their armpits. If too much sweat wets their clothes, it will have a great impact on their image. There are many reasons why girls sweat too much. Different methods need to be taken for different reasons to solve the problem thoroughly!

1. What is the reason why girls sweat a lot under their armpits?

Normal factors:

1. Temperature: Sweating itself is also a way to regulate body temperature and dissipate heat. The temperature is high in summer, so the armpits will naturally sweat more than usual.

2. Diet: Eating spicy foods such as garlic, onions, cruciferous vegetables, peppers, curry, etc. frequently will increase body temperature; drinking coffee frequently, caffeine can stimulate the nervous system and easily lead to excessive sweating under the armpits.

3. Intense exercise: When exercising, if the environment is overheated or you exercise excessively, nerve cells will transmit information to the hypothalamus. As a response to the heat, the hypothalamus will activate sweat glands, causing sweating under the arms.

Abnormal factors:

1. Abnormal secretion of apocrine sweat glands: The apocrine sweat glands under the armpits secrete some organic substances, which produce unsaturated fatty acids under the decomposition of bacteria, causing sweating under the armpits and emitting sweat odor. After a little exercise in the summer, the apocrine sweat glands secrete vigorously due to endocrine influence, thus producing a little sweat odor.

2. Caused by disease

Endocrine diseases such as hyperthyroidism and diabetes may affect the secretion of sweat glands and cause underarm sweating;

Sympathetic nerve damage or abnormal response leads to increased secretion of acetic acid and bile alkaloids, causing the eccrine glands to secrete excessive sweat;

High blood pressure, menopause and the effects of adrenocortical hormone may also cause underarm sweating in the summer.

3. Hyperhidrosis: Hyperhidrosis is a disease in which one sweats frequently, excessively, and for no apparent reason. Primary hyperhidrosis is caused by overactive sweat glands, which leads to excessive sweating under the armpits. Secondary hyperhidrosis is associated with health problems such as menopause, high blood pressure, and heart disease.

2. Reasons for armpit odor after sweating

There are many reasons why sweat from the armpits can cause odor. There are two types of sweat glands in the human body. One is small and distributed throughout the body. Its main function is to sweat and regulate body temperature. The other is larger, called apocrine glands, which are distributed in the armpits,

The genitals and other special areas, among which the armpits are the most common. This is why people often sweat more under their armpits.

The apocrine glands in the armpits secrete some organic substances, which, when decomposed by bacteria, will produce unsaturated fatty acids, thus causing sour and smelly sweat under the armpits. After you do a little exercise in the summer, the secretion of the apocrine glands will be very vigorous due to the influence of the endocrine glands, so a little odor will be produced at this time.

3. Self-test whether sweating is normal

Want to know if you have pathological hyperhidrosis? It's simple. Turn on the air conditioner and adjust it to 26-28 degrees Celsius. Sit quietly for a while. If you are still sweating, or you sweat profusely after a little activity, then you may be suffering from "hyperhidrosis".
