Everyone will grow old. This is the inevitable way, and no one can escape. Silver threads appeared in the originally dark hair; The originally smooth face showed fine lines; The original graceful figure is getting fatter... All these changes are due to our old age. Although nostalgia for the past, nostalgia for once young oneself, we should finally accept aging calmly. In fact, the aging of the human body is omnidirectional, not only the hair becomes white, wrinkles increase, and strength decreases.

When to start aging

Skin aging:
From the age of 20, our skin began to age, no longer as shiny and elastic as before. With the growth of age, the skin on the face and body may be dry, and the skin will become sallow and lose luster. Some people may also have age spots or skin itching and other symptoms.

In addition to natural aging due to aging, skin aging may also be accelerated by sunlight, mechanical effects, bad living habits, pollution, excessive beauty and other reasons. If the symptoms are mild, they can be improved by appropriately adjusting their living habits, such as keeping regular work and rest time, eating some food rich in vitamins and collagen, and doing a good job of sunscreen when going out.

Muscle aging:
From the age of 30, our muscles begin to degenerate. If we do not pay attention to scientific exercise, the muscle will be reduced by 3% to 5% annually after 60 years of age, and more than 50% annually after 70 years of age. Too few muscles will not only make people weak and walk unsteadily, but also affect their healthy life span.

Renal aging:
From the age of 30, the kidney will also gradually age, but there is no obvious sign of aging. As the Internal Classic of Traditional Chinese Medicine says, "When you are 40 years old, your yin will be half and half, and your daily life will decline", which means that at the age of 40, the functions of all organs of the human body will gradually decline, and the kidney is the mother of the five internal organs. The decline of body functions has a lot to do with the kidneys. Many people have such a feeling that the function of holding urine of many elderly people is weakened, and they need to go to the bathroom many times at night. The most intuitive thing is that Su Daqiang in the TV series Everything is OK goes to the bathroom very frequently, which is a sign of aging and weakness of the kidney. From now on, we should pay attention to the maintenance of our kidneys. However, we should not indiscriminately use "kidney tonifying" drugs or health care products. It's useless! There are several calcified spots and small cysts in the kidney, which are also signs of aging.

Brain aging:
Since we were about 35 years old, our brains began to decline, and we can no longer learn as much as we did in primary school. Because the number of nerve cells in the brain decreases with age, which has a certain impact on coordination, memory and brain function. The brain has the strongest learning and memory ability in adolescence. Once the brain is used less, the brain will begin to age.

Aging of bones:
From the age of 35, our bones began to age, and we could not be afraid of falling or touching as before. The older you are, the more osteoporosis is, and the more likely you are to fracture.

Heart aging:
Since the age of 40, the heart has gradually aged, many people's coronary arteries gradually appear atheromatous plaque and calcified plaque, diastolic function begins to decline, and "valves" such as mitral valve, tricuspid valve and aortic valve begin to show insufficiency or regurgitation.

Lung aging:
Since the age of 40, the aging rate of lungs has also accelerated. You can't easily run thousands of meters like you did in your teens, and your lungs can't support so much exercise.

Lung aging:
Since the age of 40, the aging rate of lungs has also accelerated. You can't easily run thousands of meters like you did in your teens, and your lungs can't support so much exercise.

After 45? Which organs begin to decline? Don't think about it. At this age, all the organs in the body are gradually going downhill. This is a natural law, and we can only accept it, whether we like it or not.

Many "problems" of middle-aged and elderly people are related to aging. We should face them objectively, not worry too much, and not over check and treatment, so as to avoid unnecessary harm to the body. For example, the physical examination of middle-aged and elderly people found that there were several small plaques in the carotid artery. It doesn't matter. Just control your blood pressure, cholesterol, blood sugar, exercise more, drink less, smoke less, and be fat less. If the plaque is relatively large and blocks half or more of the vascular cavity, you should seek active treatment from a doctor.

Avoid premature senility and do these things well

The speed and degree of aging are mainly determined by genes. Although we can't resist aging, if we learn to maintain scientifically, we can age more slowly.

However, we should remind you that the supplements, health care products, secret prescriptions and the like will not be effective. Don't believe in some advertising. The most feasible way is to develop healthy living habits, including reasonable diet, controlling calorie intake, active exercise, maintaining ideal weight, living rules, sufficient sleep, relaxed and happy mood, no smoking and less drinking. Check your body regularly. If you find abnormal blood pressure, blood lipid and blood sugar, you should treat them as soon as possible. Don't wait for problems in your heart, brain and kidney to pay attention to them.
