Why do old people tend to have 'old stink'? Reminder: 4 things to do after the age of 40 to help get rid of old age

In life, when we come into contact with many elderly people, we can often smell a strange smell, which is not exactly the same, but it is not indescribable either. This flavor is often referred to as aged or aged. So why do old people smell like old people?

01

Does old age really exist?

In fact, not only the elderly in China, but also researchers from the United States, Sweden, Japan and other countries.

They collected body odors from people of different ages and then asked participants to use their noses to distinguish them. People can usually tell exactly which smells come from older people.

According to the experimental results, among the men participating in the experiment, men aged 45 to 55 smelled the least pleasant; women aged 45 to 55 smelled better than women aged 75 to 95. "Adding age stinky" is sometimes called "uncle stinky", but it actually makes sense.

The reason for the smell of old people is the substances that come from our body. One is called old man. The substance "diacetyl" peaks at the age of 30-40, and another called "2-nonenal" starts around the age of 40. This substance has a higher concentration in the human body and increases with aging. Both All have a "special smell".

How does the smell of old age come about?

body function aging

The smell of the elderly is related to the aging of body functions, because after old age, the urinary system, digestive system and reproductive system gradually decline, prone to various problems such as urinary incontinence, poor gastrointestinal function, and prostate disease. For example, the elderly are stained with urine stains, secretions, etc., which give off a special smell.

With age, the toxins in the body's metabolism slow down, and then the body can easily secrete oil, and then with the appearance of some dandruff, it may be absorbed by the body, so there may be old age odor.

less cleaning

The elderly move slowly, take baths, wash their hair, and change clothes less frequently, and if they do not wash for a long time, they are prone to unpleasant odors. Some elderly people are weak and afraid of cold, so they don't open windows often for ventilation, which leads to stale indoor air and a certain smell.

Family members can often help the elderly take a bath, change clothes, and open more windows to ventilate the room, so that the air is fresh and can effectively reduce odors.

skin oxides

At the same time, when analyzing human skin oxides, it was found that one of them is called 2-renal, which belongs to aldehydes and has a strong taste. It can be said that everyone has it.

Especially at a certain age, the smell is heavier, and this smell may be more common among some people in their 80s and 90s.

disease caused

The elderly may be related to chronic diseases, some chronic diseases can cause the body to emit a special odor, such as rotten apples in diabetic patients;

People with chronic kidney disease and kidney failure can smell salty fish; people with caries and periodontitis can have bad breath, and people who regularly smoke and drink can have a strange mix of odors.

Eating more catechins in green tea, isoflavones in soybeans, polyphenols such as sesamin in sesame seeds, vitamin C, vitamin E, beta-green and yellow vegetables and other antioxidant foods such as carotene are high.

• pay attention to cleaning

Older people's taste comes mainly from the neck, ears, chest, armpits, and other places where the sebaceous glands are concentrated. The Japanese study also found that the taste of the elderly is most pronounced on the head and back of the brain. People who haven't experienced this phenomenon may really not know that this part is indeed more serious.

Therefore, the elderly should keep these parts clean, wash the neck and ears frequently, especially the head and back of the head, and change clothes frequently. Tights for the elderly are also prone to depositing dead skin and must be changed after bathing.

• Treatment of primary disease

For example, bad breath caused by calculus can be improved by scaling your teeth. Iodophor can be used for symptoms caused by folliculitis and bedsores, along with oral or topical anti-inflammatory medications as recommended by your doctor. Elderly people who are inconvenient to move should also strengthen nursing care, and regularly turn over and pat their backs to avoid deterioration of the condition.

• Diligent ventilation

Many elderly people have a hobby of hoarding items, and accumulating too much useless debris can easily lead to dust accumulation, moldy and corrupt items, and naturally easy to have peculiar smell. It is recommended that the elderly clean the room frequently, open the windows for ventilation, and keep the indoor air fresh.

Don't worry too much about the old age smell. It's not a sign of health problems or a shortened lifespan. After the appearance of the elderly, if you can pay attention to personal hygiene, quit smoking and drinking, and eat a light diet, the taste of the elderly will gradually fade.
