First, sweat gland differences
Body odor is largely derived from the odor secreted by human sweat glands. Medical research has found that there are about 3 million cells, 100 sweat glands, more than 20 seborrheic pores and 10 hairs per square centimeter of human skin. If there are a large number of sweat glands, the bacteria on the skin surface will decompose the sweat secreted by sweat glands, thus emitting an unpleasant smell.
However, due to the different number of sweat glands in each person, some people have heavy body odor, while others have poor body odor.
Second, eating habits.
Eating habits can lead to different body odors. According to the investigation and study, in Europe and America and other countries that often eat meat, both men and women have a heavy body odor, while in areas dominated by vegetarianism, the body odor is shallow.
At the same time, leeks, garlic, onions and other ingredients have a strong smell. After eating, one part is exhaled through the mouth, the other part is absorbed by the digestive tract and excreted from the skin in the form of sweat. Regular consumption may produce a strong human taste. Such as regular consumption of jasmine, aloe, almonds, figs and so on. It may give off a perfume-like body fragrance. Another example is the newborn baby, because it often eats dairy products, it will have a strong "milk smell".
Third, physical illness.
Diseases such as body odor and aphtha will affect people's body odor. Body odor is the exuberant secretion of sweat glands in armpits, perineum and other parts, which produces "body odor" and makes the human body stink. For example, patients with liver diseases and oral diseases may also emit unpleasant smells from the inside out through oral taste.
In a situation like the above, scientific treatment is needed to treat both the symptoms and the root causes, so as to change your body odor.
Fourth, lifestyle.
Different lifestyles will cause different body odors. For example, if you are lazy, don't brush your teeth, don't change clothes frequently, don't take a bath often, don't pay attention to your daily cleaning, and smoke and drink for a long time, you will naturally smell "smelly" from the inside out, which will be called "manly".
On the contrary, in daily life, as long as we pay attention to personal hygiene, do personal cleaning in time and develop a healthy lifestyle, we will keep the unpleasant smell away and make ourselves "delicious".
Verb (abbreviation of verb) emotional factors
Long-term anxiety, nervousness and bad temper will lead to changes in human endocrine, make nerves too excited, lead to a large number of sweat glands secretion, and easily produce too much body odor.
