10 organ warranty period 1. Liver: warranty period is 70 years.
The liver is the organ that stays in the human body for the longest time, and it is also the only organ that can challenge the aging process. Hepatocytes have a strong regenerative ability. After surgical resection of a part of the liver, as long as the remaining proportion exceeds 25%, it will grow into a complete liver within 3 months. If the donor does not drink or take drugs or has no infectious diseases, then the liver of a 70-year-old can also be transplanted to a 20-year-old.
How to keep the liver healthy?
The two keys to protecting the liver are "keep your mouth shut and keep your legs open". The first thing is to drink less. Alcohol can be said to be the "natural enemy" of the liver, and excessive drinking can easily lead to alcoholic hepatitis. In addition, we should eat less high-calorie foods and adopt a diet principle of high fiber, high protein, low fat and low sugar. At the same time, we should maintain moderate exercise, including jogging, brisk walking, cycling, badminton, swimming, etc., which will help protect liver function.
Second, the intestine: the warranty period is 55 years.
A healthy intestine can play a good balance between harmful bacteria and beneficial bacteria. After the age of 55, the number of probiotics in the intestine began to decrease greatly, which reduced the digestive function of the human body and increased the risk of intestinal diseases. With the increase of age, the peristalsis function of small intestine also begins to decline, and the probability of constipation will also increase.
How to keep the intestines healthy?
To keep the intestines young, we must first adhere to a balanced and reasonable dietary structure. Second, choose your favorite exercise and persevere, and often do push-ups, which is conducive to strengthening abdominal muscles, promoting intestinal peristalsis, accelerating fecal excretion, maintaining the balance of intestinal flora, and preventing premature aging of the intestine.
Three. Kidney: The warranty period is 50 years.
The renal filament ball in the kidney can filter out the waste in the blood stream, and the filtration rate of the renal filament ball has decreased since the age of 50. As a result of the decrease of filtration rate of renal filament ball, the ability of viscera to filter toxins becomes worse, so that more and more toxins accumulated in blood can not be excreted with urine. The filtered blood volume of 75-year-old man's renal filament ball is half that of 30-year-old man.
How to keep the kidneys healthy?
In order to protect the kidneys, we should have enough rest and drink enough water. We need to drink 1500 ~ 2000 ml of water every day, and the daily urine output should be kept at around 1500ml. In addition, to avoid getting cold at the waist in winter, you can use your feet and hands to rub around the waist to maintain your kidneys.
Fourth, the heart: the shelf life is 40 years.
With the aging of the body, the efficiency of the heart to deliver blood to the whole body begins to decrease, because the blood vessels gradually lose their elasticity, and the arteries may become hard or blocked, and then the blood delivered to the heart decreases, causing angina pectoris. Men over the age of 45 and women over the age of 55 will gradually increase their chances of heart attack.
How to keep your heart healthy?
If you want to keep your heart healthy, you should avoid eating and living habits such as smoking, overeating and lack of exercise. Through a balanced diet, continuous and fixed exercise habits, and rational face of environmental pressure, you can keep your heart strong and young.
Five, teeth: shelf life of 40 years.
People's permanent teeth can chew food for a long time except for tooth decay or external factors, but they also have their shelf life. Saliva secreted in the mouth can wash away bacteria. When people get old, the amount of saliva secretion will decrease, and teeth and gums will be more easily damaged. When periodontal gingival tissue is lost, the gums will shrink, which is a common condition for adults over 40 years old.
How to keep your teeth healthy;
In order to keep your teeth healthy, please use health insurance and wash your teeth twice a year to keep your teeth away from bacteria, which can make your gums firm and not shrink. In addition, you should also choose a suitable toothbrush (the bristles should not be too hard), interdental brush and dental floss to remove tartar. If you brush your teeth instead of rotating your toothbrush, your gums may shrink prematurely.
The intransitive verb eye: the warranty period is 40 years.
Andrew Roth, a professor of ophthalmology at the University of Southampton in the United Kingdom, said that with the growth of age, people's eye muscles will become weaker and weaker, and the focusing ability of the eyes will begin to decline, and the symptoms of presbyopia will gradually appear. The culprit of eye aging is free radicals. For example, ultraviolet rays and radiation are light sources of free radicals. These free radicals can lead to the oxidation of eyeball cells, from decreased vision to cataract, macular degeneration and retinopathy.
How to maintain the health of eyes?
In addition to forming the habit of using 3C products for a limited time, maintaining a good reading posture and giving your eyes a full rest, you can also take lutein, a carotenoid with antioxidant effect. It exists in human retina, and its main function is to concentrate on cornea and eye cells and absorb free radicals.
Seven. Bones: The warranty period is 35 years.
Generally, the human body will experience bone loss from the age of 35 and enter the natural aging process. However, postmenopausal women lose bone faster, which may lead to osteoporosis, and the prevalence rate reaches 10.75%. The decrease of bone size and density may lead to the decrease of height. The bone in the middle of the vertebrae will shrink or break. A person's height at the age of 80 will be 2 inches lower than that at the age of 20.
How to keep bones healthy?
A large number of studies have proved that exercise is helpful to increase bone mineral density, especially jumping exercise such as skipping rope, which plays an important role in improving bone mineral density. In addition, exercise can improve the blood circulation of bones, enhance the material metabolism of bones, improve the elasticity and toughness of bones, and delay the aging process of bone cells. In addition, calcium should be supplemented in time after the age of 40 to make up for the gradual natural loss of calcium in bones.
Eight, leather: shelf life of 25 years.
As collagen production slows down, skin will naturally age around the age of 25. Due to the growth of age, the skin barrier function gradually degenerates, and skin problems such as dry skin allergy, eczema, dermatitis, aging, pigmentation, etc. may also occur.
How to keep the skin healthy?
Andrew Wright, a doctor at the National Health Trust in Bradford, UK, said that the best way to keep skin healthy and young is to protect its barrier function. Usually, you can apply some lotion with barrier repair function, which can effectively enhance skin immunity and make skin tough. In addition, eating more healthy fat can keep the skin soft, moist and radiant. Experts suggest that washing your face with cold water or water close to the skin temperature is most suitable for maintaining your skin.
Nine, the brain: the warranty period is 20 years
With the increase of age, the number of nerve cells in the brain gradually decreases. When human beings were born, the number of nerve cells in the brain reached about 6543.8+000 billion, but it decreased year by year from the age of 20. At the age of 40, it began to decline at the rate of 10000 per day, which further affected memory, attention and sensory ability.
How to protect brain health?
Free radicals are the enemy of the brain. Antioxidants can neutralize free radicals, thus preventing the persistent attack of oxygen free radicals on body cells and protecting the function of nerve cells. In addition, of course, we should eat less junk food that will produce free radicals and block blood vessels in the brain. Also, keep thinking or learning new things and activate nerve cells that use the brain.
X. Lung: The warranty period is 20 years.
The vital capacity of the human body began to decline slowly from the age of 20, and by the age of 40, some people began to asthma with a little strenuous activity. At the age of 30, men will inhale an average of 946 ml of air every breath, but by the age of 70, it will drop to about 473 ml, leaving almost half of their vital capacity.
How to protect the health of lungs?
The most important thing is to keep the air in the living environment and avoid inhaling too much harmful air. In addition, it is also important to ban smoking completely and avoid second-hand smoke. At the same time, maintaining moderate and fixed exercise habits can strengthen the development of cardiopulmonary function.
