Why does the old man have a smell? Suggestion: 4 habits to stay away after 50, old or tasteless

Why does the old man have a smell?

Where does the smell on the old man come from? There are currently different opinions.

Not long ago, a seven-year survey by a Japanese research institute found that the culprit of the smell of the elderly is a substance called diacetyl, which tends to reach high levels when people are in their 30s and 40s, according to China News Agency. the value of.

A 2001 study by Japanese dermatologists also found that people's body odor contains high concentrations of 2-nonenal starting around the age of 40, and its secretion increases with age. Both substances have a characteristic odor.

Young skin has natural antioxidant power. The antioxidant quality of elderly skin declines with age. Hormonal changes lead to more oxidation of free fatty acids, including accumulation of nonenal, leading to a characteristic odor. Therefore, from the above research, the taste of the elderly has a certain relationship with the increase of age.

So, are old age an inevitable consequence of aging? This is not the answer. Li Haicong, director of the Department of Geriatrics at the China-Japan Friendship Hospital, believes that the odor of the human body is caused by a variety of factors. In addition to sweat glands, there are microorganisms such as bacteria and fungi on the body surface.

In addition, the smell of the elderly may also be a signal of certain diseases. When people get old, their skin resistance decreases and they are more susceptible to infection, which leads to skin diseases such as dermatitis, eczema, ulcers, and sores, which emit odor.

Coupled with chronic diseases such as diabetes and uremia, the skin function is poor, and there will be peculiar smells. For example, patients with uremia have the smell of urea, and patients with liver cirrhosis have the smell of rotten apples.

In addition to physical reasons, it also has a lot to do with personal living habits. The function of sebum metabolism in the elderly is reduced, and it is easy to dry and peel, resulting in dandruff and dead skin. If it is not cleaned in time, it will produce odor.

Why does the old man have a smell? Suggestion: Stay away from 4 habits after 50, old or tasteless.

★ Work hard on diet.

As the saying goes, many diseases come from the mouth, which has a lot to do with unhealthy eating habits. For older adults, their metabolism slows down with age. As mentioned above, the development of taste in the elderly is closely related to metabolism and eating habits.

Therefore, in order to alleviate the taste problems of the elderly, we should adjust our diet in time. At a certain age, we should reduce the intake of high-oil, high-greasy, spicy and irritating foods, appropriately increase high-fiber foods, eat more fresh vegetables and fruits, add water, and enhance immunity.

★ After the age of 50, try to avoid smoking as much as possible.

Today, many elderly people have the habit of smoking, and generally, they smoke from young to old age. I usually smoke 1-2 packs of cigarettes a day.

And we all know that smoking increases the risk of lung cancer, and it also compromises liver function, leading to decreased liver function, accumulation of large amounts of toxic wastes and carcinogens in the body, and accelerated aging.

In addition, people who smoke for a long time, we will also find that their teeth are yellow, the mouth smells, and the body will also have a fishy smell. Therefore, in order to reduce the smell of the elderly, it is necessary to remind the elderly to quit smoking in time and stay away from harmful substances. bodily injury.

★Control blood sugar

In order to prevent body odor from seriously affecting personal image, the elderly should control blood sugar as soon as possible.

During the process of increasing blood sugar, diabetes may be caused. During the development of diabetes, the body may release ketones with a distinct smell. If blood sugar can be controlled as soon as possible to prevent diabetes, it will also help prevent the elderly. taste.

★Insist on brushing your teeth

Many seniors do not brush their teeth, but as they get older, they are more likely to smell various odors in their mouths, so they must do good oral hygiene and try to maintain the habit of brushing their teeth every morning and evening.

Because brushing your teeth can effectively clean mouth odor, keep your mouth fresh, or rinse your mouth after meals, because rinsing can remove food residues in the mouth, thereby effectively avoiding odors in the elderly.

At what age do people become physically stinky?

After puberty, fatty acids secreted by human sebaceous glands are oxidized to produce palmitic acid, which is a fatty acid, but after the age of 30, sebum oxidation secretion becomes more and more serious, and fatty acids and lipid peroxides combine to produce unsaturated aldehyde-2-nonyl Aldehyde, a microbial decomposition smell that some say is close to the smell of industrial cardboard.

But generally by the age of 50, the smell will be deeply smelled.

In addition, the older a person is, the weaker the metabolic capacity and the slower the metabolic capacity. People's ability to break down skin, hair, and other metabolic waste gradually diminishes. If they don't bathe and change clothes frequently, their bodies can emit a putrid-like odor, which is stronger when sweat and sebum adheres to their underwear.
