What are the causes of body odor?

In hot summer, people sweat easily. Sweat flowing out of the body will easily produce an odor if it stays on the body for a long time. Generally speaking, this smell is normal, but there are also some abnormal situations. For example, many men sweat easily and have a huge unbearable smell. This is what we often call body odor. So what is the cause of body odor?

1, the cause of body odor

(1) excessive pressure

From the composition of chemical substances, sweat can be divided into many kinds, of which the most unpleasant smell is that sweat flows out under pressure. This is because it is secreted by a sweat gland called apocrine gland.

Sweat secreted by apocrine gland has low water content, and bacteria have been propagated in the mixture of fat and protein in sweat, so the smell is heavy. Sweat during exercise or hot weather is mainly composed of water and electrolyte, and the smell is not so strong.

(2) heredity

Sweat secreted by feet contains a lot of bacteria. Because toes are in a dark, warm and humid environment, it will create ideal conditions for bacteria to grow, especially when wearing socks.

But 10%~ 15% people were born with love sweating's feet. This particularly humid environment will become a hotbed of a specific bacteria (inhabiting micrococcus), which will produce sulfide, an unpleasant smell.

(3) Suffering from fishy smell

This is a rare disease, which is caused by a specific gene mutation. It will prevent the human body from decomposing a compound called trimethylamine. Trimethylamine can make fish smell;

When it accumulates in the human body, it will be released through breathing, urine and sweat, making patients smell fishy. This smell is unacceptable and usually leads to depression or social isolation.

(4) Drinking

When people drink, alcohol will flow through the body through blood circulation, and some alcohol will seep out through pores; Some will give off with the breath, making people smell an unpleasant smell of wine. The type of wine has no effect on the odor produced by human body. As long as the body starts to decompose alcohol, the smell is the same.

(5) There may be diabetes.

If diabetes worsens, it may develop into diabetic ketoacidosis. Because there is not enough insulin in the patient's body, the body will start to break down fat as fuel, leading to the accumulation of ketones in the body. This accumulation will cause changes in body odor and body odor. At this time, it is necessary to seek medical treatment in time.

2. How should men stay away from body odor?

1, natural evaporation

The evaporation of sweat in midsummer is the main or only way to dissipate heat. On the premise of not affecting the activity, you can not wipe off the sweat that just oozed. Try to increase the exposed area of limbs in the air without affecting elegance. Heat dissipation is fast, and the amount of sweating will naturally decrease. Sweat in summer and keep healthy.

Step 2 prevent fatigue

In summer, we should try our best to reduce sweating, reduce sweating speed, and at the same time strengthen nutrition and supplement enough salt, including eating more vegetables, fruits and salty soup, and drinking some light salt water or salt soda when necessary.

If you want to exercise and don't want to sweat, wear quick-drying sportswear. The so-called quick drying refers to clothes made of special fibers, which can lose water faster and keep people dry compared with cotton and wool clothes.

The principle of quick-drying fabric is to expel the sweat from the human body surface as quickly as possible, and then diffuse and evaporate from the fabric surface to make the body dry faster. The evaporation of sweat is beneficial to reduce the body surface temperature, avoid heatstroke and avoid the influence of excessive sweat on sweat glands.

6, shower gel

Soap is alkaline, which will destroy the stratum corneum and make the skin more dry and sensitive. Moreover, the shower gel with moisturizing effect is the best choice for men to clean in summer. Men's shower gel generally contains natural plant formula, which can gently clean the whole body.

Many brands also introduce men's shower gel with cool formula for hot weather in summer, such as mint shower gel, which gives people a refreshing feeling. There are also some products with different scents, such as lavender and dried amber. The lasting and faint fragrance not only relaxes people, but also brings a good smell to men.

Step 7 spray perfume

Perfume is the most urgent way. But choose the perfume that suits you, and don't wear too much. Too strong perfume and sweat smell is really hard to smell.

3. The difference between body odor and sweat smell

(1) The difference between body odor and sweat odor

There is no obvious difference between body odor and sweat odor. The body odor is relatively large, and the sweat odor is relatively small. Body odor, also known as underarm odor, is heavy and easy to make others feel uncomfortable.

(2) the formation of sweat smell

Sweat glands that secrete sweat can be roughly divided into eccrine glands and apocrine glands. Eccrine glands are distributed all over the body, and the discharged water contains only a small amount of salt and urea lactate. Apocrine glands are sweat glands attached to hair and distributed in armpits, areola and female private parts. Sweat is a dilute liquid secreted by sweat glands, in which water accounts for 99%. Sweat itself has no odor, but it will produce odor when mixed with bacteria on the skin surface.

(3) Distribution of sweat and odor

After exercise, sweat will reach the highest point. Because of the damp heat on the body surface, it provides an ideal breeding environment for bacteria. The most common parts of sweat smell are armpits, feet, thighs and abdomen. Bacteria are easy to accumulate, sweat glands are relatively more, sweat is not easy to evaporate, and the smell is strong.

For sweaty people, chrysanthemum or mint can be soaked in water in summer, which can achieve the effects of clearing away heat and toxic materials, soothing the liver and relieving depression and qi stagnation, thus reducing the smell of sweat.
