Uncle Yan hugged his grandson this year, and after a few months, the child has gradually grown up, but I don't know why, every time Uncle Yan hugs his grandson, the child can't stop crying. But when the daughter-in-law and son, and even the wife and the child were holding the child, the little grandson was very quiet and did not cry at all.
On this day, when Uncle Yan participated in the physical examination of retired employees of the unit, he inadvertently chatted with his friends about this topic. My friend felt that it might be that Uncle Yan had the smell of an old man, and the child's sense of smell was more sensitive, so he didn't like this smell very much, so Uncle Yan scratched his head and felt that what his friend said was very reasonable.
So, what exactly is the smell of the elderly? Why is it only smelled in the elderly? Today, we might as well find out.
1. If you can't smell it, others don't dare to approach? Where does the smell of the elderly come from?
Over the years, scientists have done a lot of research on this phenomenon and found that the old man's taste does exist, and in fact, it is not very related to personal life Xi, mainly caused by the slow metabolism of the human body.
The reason for the appearance of old age smell is that the key lies in an unsaturated aldehyde, that is, 2-nonenal.
Some Japanese scholars have found that 2-nonenal will only appear in people over 40 years old, and middle-aged people over 40 years old have actually begun to age, and there are many causes and manifestations of aging, one of which is oxidation.
Young people have a lot of antioxidants in their bodies, so they can well remove harmful substances formed after metabolism secreted by the skin, such as 2-nonenal.
In addition, young people have stronger blood vessel function and faster blood circulation, which will accelerate the discharge of "toxins" from the whole body, that is, the speed of metabolism is faster, so the 2-nonenal secreted by the skin is easily excreted with the blood.
However, when a person reaches a certain age (it depends on the person, but it will be after the age of 40), the body's antioxidant substances will decrease, and the metabolic rate will also slow down.
Of course, it's not all 2-nonenal that causes the smell of the elderly. As we age, our metabolism slows down, and the skin is more prone to dead skin, which will be broken down by bacteria on the surface of the body if not cleaned up in time, which will also produce a strange smell.
Finally, long-term greasy diet, sedentary and insomnia and other bad Xi will promote the secretion of sebaceous glands, and the cholesterol content in the blood will also increase, which will also produce odor, and it is for this reason that men are more likely to have old age odor than women.
However, people who have the smell of old people may not smell this smell, because there is a medical term called "olfactory adaptation", which means that people generally cannot perceive their own smell very sensitively.
But then again, isn't it even more embarrassing for others to smell the smell on their bodies? How to get rid of the smell of the elderly? Presumably this is also a question that many people want to know.
2. How to get rid of the smell of the elderly? The doctor will teach you these 4 tricks
1. Regulate your diet
Many people don't know that one of the very important ways our bodies strengthen our metabolism is through bowel movements.
For the elderly, the function of the large intestine has deteriorated, and the intestinal peristalsis has slowed down, which will lead to poor bowel movements in the elderly, and "toxins" are more likely to accumulate, and the elderly can accelerate metabolism by adjusting their diet to promote intestinal peristalsis.
For example, fruits and vegetables are one of the best foods to promote gastrointestinal peristalsis, fruits and vegetables are rich in enzymes, which can inhibit oxidation in the gastrointestinal tract, delay the aging of the gastrointestinal tract, and accelerate metabolism. In addition, enzymes can help break down food, which can also improve symptoms such as constipation and speed up the elimination of "toxins".
2. Exercise
Exercise is always a great way to stay healthy compared to diet.
We all know that one of the biggest meanings of exercise for people is to burn fat, which is to reduce the production of cholesterol, and the natural old age smell is less.
Another significant meaning for people is "detoxification". When the parasympathetic nervous system is excited, the blood flow speed will increase, and the toxins in the whole body will be brought to the kidneys in the process of blood circulation, and then excreted with the urine. Therefore, the blood flow rate is faster, and the body's detoxification efficiency is naturally higher.
Another way of exercise detoxification is not too obvious, that is, in the process of exercise, the stomach and intestines also "move". Intestinal peristalsis is faster, and stool is easier to pass. Pooping itself is also a form of detoxification. Of course, it's not enough to just exercise, but also to relax when you're tired!
3. Learn to relax
If the elderly person is constantly in a state of tension, then the sympathetic nerves will be excited and the blood vessels will constrict, which will lead to an increase in blood pressure, slow down the flow of blood, and be detrimental to metabolism. Therefore, the elderly should learn to relax, find certain hobbies, and soothe their mood, such as meditation, social activities and other activities.
4. Bathe often
In the process of bathing, it will directly wash away dead skin and pathogenic microorganisms on the skin, and can also directly remove odors.
In addition, bathing can also promote the dilation of blood vessels, especially those on the surface of the body. This accelerates blood flow to the body, allowing skin cells to better absorb nutrients, improve the skin's immune function, and alleviate the oxidative process.
But for the elderly, taking a bath in winter is actually a relatively dangerous thing. Cases of elderly people bathing and causing various diseases and causing serious injuries and even deaths are often reported in the newspapers. It is estimated that more than 10,000 people die each year in Japan as a result of bathing.
Therefore, when the elderly take a hot bath in winter, they must pay attention to these points.
Don't let winter bathing become a problem for the elderly
1. Don't bathe on an empty stomach
Blood flow is faster when bathing, so the metabolism will be faster, which will cause people to burn energy faster when bathing.
Therefore, for the elderly, if they take a bath on an empty stomach, they are more likely to have low blood sugar, which is manifested as dizziness and weakness of the limbs, and in severe cases, accidents may occur due to falls.
Therefore, it is recommended that the elderly do not take a bath on an empty stomach, and it is best to keep it full, or eat some high-sugar foods such as chocolate and candy before bathing.
2. Take a shower an hour after eating
You can't take a bath on an empty stomach, but you can't take a bath just after eating.
Because after eating, the mucosal blood vessels of the gastrointestinal tract dilate, and the blood of the whole body will collect in the digestive tract. At this time, there is less blood in the brain, and if you take a bath, the blood will return more to the epidermis, which will make the brain tissue less blood, and the elderly may have cerebral ischemia and faint.
It is recommended that the elderly finish eating for an hour, wait until the gastrointestinal digestion for a while before taking a bath, or drink a glass of boiled water before bathing, which can replenish water and prevent telangiectasia from causing excessive water loss.
3. Bring a bench with you in the shower
The elderly can bring a bench when taking a bath, so that they can sit for a while when they are tired to prevent them from slipping due to lack of physical strength. In addition, it is better to have a wooden bench, because plastic stools are not strong and tend to get slippery.
4. Don't take a shower for too long
Because the ventilation of the general bathroom is relatively poor, the temperature is high, and the humidity is high, so the oxygen content in the bathroom is less, and if the bath time is too long, the elderly may appear in a state of hypoxia.
Moreover, if the elderly take a bath for a long time, it will cause the skin blood vessels to dilate excessively, and the blood of the whole body will pour into the skin blood vessels in large quantities, resulting in insufficient blood supply to key organs, especially the brain, thereby inducing adverse consequences such as syncope.
Write at the end
In short, the smell of old age is a very normal phenomenon, and it is also a manifestation of our aging. However, taking some appropriate measures can reduce and weaken the smell of the elderly to a certain extent! One of the most important is to take a bath, but for the elderly, take a bath in winter to pay more attention!
