Let's first understand how body odor is produced.
Scientific discovery;
Body odor, also known as underarm odor and smelly sweat, is the sweat discharged from the apocrine glands (also known as apocrine glands) in the armpits, vulva and corners of the mouth of patients, and its fatty acid is higher than that of ordinary people, showing light yellow and thicker; When fatty acids reach a certain concentration, they are decomposed by bacteria on the skin surface, mainly staphylococcus, producing unsaturated fatty acids and giving off a bad smell. It is similar to the smell discharged from fox's anus, so it is often called body odor.
1. Apocrine sweat
Apocrine glands only exist in axilla, areola, umbilical fossa, anus, vulva and external auditory canal, and the function of other parts except axilla is extremely weak, resulting in little sweat. Sweat secreted by apocrine glands is sterile at first. Under the action of microorganisms, the organic matter in sweat decomposes to form short-chain fatty acids and ammonia with special odor, which leads to the occurrence of apocrine glands.
2. Eccrine hyperhidrosis
Often occurs in the palm and sole, rubbing area, and sweating is often colorless and tasteless. However, in the case of hyperhidrosis, sweat is interpreted by parasitic bacteria on the skin surface to release fatty acids and produce a special smell; Other substances such as garlic and arsenic can be excreted through exocrine glands, thus producing odor.
3.？ When the mental or nervous system is damaged (such as paranoia, schizophrenia, etc. ), it will also produce smelly sweat.
4. The occurrence of bromhidrosis may be related to heredity.
Reason 1. hereditary factor
Many prospective parents or new parents are particularly worried that their body odor will be passed on to their children and will be gone at birth. How is body odor inherited? Here's a detailed introduction from the genetic law. I hope everyone can get rid of the unknown body odor and fear!
(1). If both parents have body odor and the mother's body odor is homozygous, then the offspring, whether male or female, have 100%.
(2) If parents have body odor and mothers are heterozygotes, the body odor rate of offspring is 100%, while that of males is 50%.
(3) If the father has body odor and the mother is normal, the body odor rate of female offspring is 100% and that of male offspring is 0%.
(4) If the father has no body odor and the mother is homozygous, the body odor of male and female offspring is 100%.
(5) If the father has no body odor and the mother is heterozygote, the body odor of male and female offspring is 50% respectively.
(6), if parents don't have body odor, offspring children must also have no body odor.
Reason 2, body endocrine
Body odor is closely related to body endocrine, such as liver and gallbladder metabolic dysfunction, gastrointestinal dysfunction or adrenal cortex dysfunction. Unsaturated fatty acids secreted by sweat glands will increase; The smell of body odor will increase.
Reason 3: Is body odor contagious?
Needless to say, I can always hear someone wearing a roommate's clothes once. Then I found that I had body odor, and then I was unhappy, so I joined the base camp of body odor.
Don't step on the following misunderstandings, stepping on them will only delay precious time.
Misunderstanding 1. Small folk remedies go up by themselves.
Alum+wormwood, lemon+honey, friends got into a fight, so I won't talk about it. I don't know. Many things are chemical products. You put that thing on your body. Wow, what refreshing skin. Excessive heavy metals, allergic. Body odor is getting worse and worse, which will do harm to human body. Therefore, please use it with caution.
Myth 2: Toothpaste can remove body odor?
If toothpaste can get rid of body odor, it is really cheap and convenient. Wouldn't it be beautiful to brush your teeth and get rid of body odor? In fact, this is not correct. Unsaturated fatty acid is a kind of stubborn bacteria, and toothpaste has no effect on it, because toothpaste is a solid viscous substance that will not penetrate below 35 microns of underarm skin. It's just the fragrance of toothpaste and its bactericidal effect that people mistakenly think that it can get rid of body odor.
Myth 3. Give up on yourself
It is impossible to get rid of body odor every day. I've been like this all my life. Think about it carefully, people's emotions affect health.
Self-information must be established, the three views must contend, and the mentality is better. As long as you believe that body odor can be eliminated, you will definitely get rid of it.
