In summer, many people sweat easily under their armpits. So, what reason is summer armpit perspiration much? Normal?
What's the reason for armpit sweating in summer
I. normal factors
1, temperature
Sweating itself is also a way to regulate body temperature and heat dissipation. In summer, the temperature is high, and the armpit naturally sweats more than usual.
2, diet
Often eat garlic, onion, cruciferous vegetables, pepper, curry and other spicy stimulating food will increase the body temperature; often drink coffee, caffeine can stimulate the nervous system, but also easy to cause underarm excessive sweating.
3. Vigorous exercise
During exercise, when the environment is overheated or over exercised, nerve cells will transmit information to the hypothalamus. As a response to heat, the hypothalamus will activate sweat glands, leading to the occurrence of axillary sweating.
Tips: generally healthy people will increase the secretion of sweat glands during exercise or in case of high temperature, which is for the physiological effect of increasing body temperature and decreasing body temperature. Therefore, fat people tend to sweat more than thin people, which is not because of the former's large body surface area, but because obese people have high body weight and their body temperature is easy to rise. In order to reduce the high body temperature, it is necessary to regulate them by sweating more.
2. In addition to the above reasons, when not sweating, a large number of sweating people in the armpit may have problems with sweat glands, etc. local hyperhidrosis may result from sympathetic nerve injury or abnormal response, and the increase of acetylcholine secretion, resulting in excessive sweat secretion from the sweat glands.
1. Abnormal secretion of apocrine glands
The sweat glands under the armpit secrete some organic substances, which produce unsaturated fatty acids under the decomposition of bacteria, cause the sweat under the armpit, and diffuse the sweat smell. After a little exercise in summer, the sweat glands secrete vigorously under the influence of endocrine, thus producing a little sweat smell.
2. Cause of disease
Hyperthyroidism, diabetes and other endocrine diseases may affect the secretion of sweat glands and cause axillary sweating;
Sympathetic nerve injury or abnormal reaction leads to the increase of acetylcholine secretion, which leads to the secretion of too much sweat from eccrine glands;
High blood pressure, menopause, and the action of corticosteroids in the accessory kidney may also lead to axillary sweating in summer.
3. Hyperhidrosis
Hyperhidrosis is a frequent, excessive and unexplained sweating disease. Primary hyperhidrosis is caused by hyperactivity of sweat glands, which leads to excessive underarm sweating. Secondary hyperhidrosis is related to menopause, hypertension, heart disease and other health problems.
There are many reasons for the peculiar smell in the armpit after sweating. There are two kinds of sweat glands, one is small and distributed in the whole body, the main function of which is to perspire and regulate body temperature; the other is large gland, called apocrine gland, which is distributed in the armpit, the vagina and other special areas, and the armpit is the most. So people tend to feel more sweat under their armpits, which is exactly why.
The sweat glands in the armpit will secrete some organic substances, which will produce unsaturated fatty acids under the decomposition of bacteria, thus causing armpit sweat and sour smell. After you exercise a little in summer, the sweat glands will be very strong under the influence of endocrine glands, so there will be a little peculiar smell at this time.
Is sweating normal? Self test to find out if you are morbid and sweaty? It's very simple. Turn on the air conditioner, adjust it to 26-28 ℃, sit quietly for a while, if you are still sweating, or if you have a little activity, you will sweat more than once, then you are likely to suffer from 'hyperhidrosis'.
How to avoid the embarrassment of armpit sweating in summer 1. Pay attention to diet
Don't eat too much spicy and irritant things, especially raw onions and other things that produce smell. It will send out unpleasant smell when it turns into sweat with the metabolism of the body. Should eat milk, bean products, shrimp skin, kelp, fish, bone soup and green vegetables and other calcium rich food.
2. Pay attention to hygiene
Sweat can only give off smell when it is decomposed by bacteria. Keeping your body clean can reduce bacteria growth and prevent armpit odor from happening. You can take a bath with disinfectant (such as dew) or disinfectant twice or three times a day. If you want to go to work and can't take a bath often, you should also wash your armpit regularly. Sweat a lot after exercise. Take a bath as soon as possible, or bacteria will breed and multiply, and the smell will be stronger.
3. Wear comfortable clothes
Some people think that wearing long sleeved clothes can mask armpit odor, in fact, it will only make the odor stronger. Because long sleeved clothes, especially sweaters, will increase perspiration, speed up the decomposition of sweat by bacteria, and the odor can not be dispersed, and it will become more and more smelly. So in hot days, summer armpit sweating how to do more should wear cool, loose, thin clothes.
4. Reduce sweating
In hot days, the condition of body odor is very serious, because there is more perspiration, so antiperspirant should be used to reduce perspiration. Antiperspirant can block the channel of sweat secretion, and has the function of sterilization and disinfection. Basically once a day can be painted, if the situation is serious, can be painted two to three times, but not too many times.
5. Drink more lactic acid drinks
Regular drinking of lactic acid drinks is still very effective in the treatment of body odor. Lactic acid drink can inhibit the growth of bacteria in the body, thus reducing bacteria discharged from the skin through sweat glands, because bacteria do not like to grow in acid environment.
6. Keep your body clean
Take a bath every day to keep your armpit clean, and wash the clothes you touch every day. Consider shaving your armpits. Armpit hair is easy to breed bacteria. In summer, when it's easy to sweat, try shaving it off.
