Why do some elderly people smell and others don t?

<> life, we find that many elderly people have a peculiar smell, which can be called "old people's smell". Japanese researchers have coined a word to describe this special smell on the elderly, called "aging odor".

Some people say that it is normal for people over 50 years old to have the smell of old people. In fact, it's not entirely true, because the smell on the body or ** body odor, or the cause of the disease, may be a sign of unhygienic or even unhealthy. So, what are the main reasons for the appearance of old people in the elderly?

The analysis here is as follows.

What are the main reasons for the elderly to have senile smell?

(1) Body odor and sweat odor caused by normal aging

With the increase of age, generally from the age of 50, people's body odor begins to contain a higher concentration of "2-nonenal", the older the age, the higher the secretion, and this substance, it has a "special smell" mixed with oily smell and weed smell.

This substance is often metabolized and disseminated from people's sweat glands, and it is easier to emit odors in a closed environment, forming an elderly smell.

In addition, as you get older, your metabolism slows down, and the surface layer is more likely to produce dead skin. The metabolism of the elderly body is relatively slow, and it is easy to have dead skin. If you don't clean up the dead skin in time, the dead skin will produce a peculiar smell over time.

In addition, sweat odor is also one of the common old people's smell**.

Bad breath

Many elderly people's teeth are generally not good, often missing teeth, rotten teeth, etc., and the gap between the teeth of the elderly is enlarged, if the food residue is not removed in time after eating meat food, the food residue in the mouth accumulates more and more, and it will lead to foul smell after fermentation.

Excretion and secretions

Most of the elderly have poor digestive function, and the ingested protein is often difficult to digest, and the undigested protein will become urea, uric acid, etc., resulting in a particularly strong taste of urine and urine. In addition, due to the decline of physical functions, such as men suffering from prostatic hyperplasia, the elderly often wet their pants, resulting in worse and worse body odor.

Lifestyle habits

Some elderly people like to eat meat, fried food, etc., but lack of sleep and exercise, etc., will lead to an increase in sebaceous gland secretion and fat, and in the long run, cholesterol will accumulate in the blood vessels, which will lead to a bad smell in the body.

Some diseases

The elderly** have low resistance and are more susceptible to infection, with dermatitis, eczema, ulcers, sores and other ** diseases, resulting in odor.

In addition, some elderly people suffering from diabetes, uremia, pelvic floor dysfunction and other diseases will also have peculiar smells in their bodies, such as urea smell in uremia patients, rotten apple smell in patients with liver cirrhosis, and urine odor in patients with pelvic floor diseases.

This is related to the physical health of the elderly, and it is also related to personal hygiene.

I think it may be caused by the aging of the body, there may be a problem with **, then there is a change in hormone levels, and finally there are symptoms of disease.

This is because there are many people who pay great attention to their own hygiene, so they often take a bath and eat relatively lightly, so these people do not have the smell of old people.
