No one is not afraid of aging, but aging faster than we imagine to be much more, the British have done research in this area, results show that before we move into old age, most organs had already begun aging. Particularly alarming is that aging is, surprisingly, the first brain and lungs, the liver of aging later.
Let's first take a look at the various organs of the aging time bar!
Brain aging time: 20-year-old
As we age, the number of nerve cells in the brain will be gradually reduced. We come alive when the number of nerve cells to reach 100 billion or so, but 20-year-old began to fall gradually. To 40 years, the number of nerve cells begin to 10000 a day rate of decline, thus memory, coordination and brain function affected. Thus, memory is often better than adults children, middle-aged memory is greatly diminished after. In addition to reducing the number of nerve cells outside the neural mesenchymal cells (cells that connect nerve cells) functional degradation is also an important reason for brain aging. The aging of these cells led to exchange of information between nerve cells is not smooth, coordination and cooperation of the capability has been greatly reduced.
Lung aging time: 20-year-old
Many athletes, the golden age is 10 years old, many of them were in the 20-year-old forced to retire, it is because the lung from the 20-year-old began to aging. To 40 years of age, some people appeared breathless condition, in part because the control of breathing, and chest muscles become rigid, making more difficult the functioning of the lung, thereby weakening the vitality of the lung, breath some air after the left in the lungs, lead to gasping. 30 years old, ordinary men would inhale each breath about 950 milliliters of air; By the age of 70, this figure dropped to about 475 milliliters, just cut in half.
Skin aging time: 25-year-old
With the slowdown of collagen is generated, coupled with the rapid elastic back elastin elasticity decreased (or even fracture), the skin around your 25-year-old natural aging. Will not soon shed dead skin cells to generate the amount of new skin cells may be slightly reduced, this is the cause wrinkles.
Muscle aging time: 30-year-old
Muscle has been related to growth, failure, re-growth, and then failure. Young people to maintain the balance of this process very well. However, after 30 years of age, the muscles faster than the growth rate of failure. After a 40-year-old man's muscles began to an annual 0.5% - 2% of the speed reduction. Regular exercise helps prevent muscle aging.
Hair aging time: 30-year-old
Male hair loss is usually the age of 30, every previous new fine hair. Finally, the remaining hair follicles are all much smaller and the thin short-pile, there is no longer out from the epidermis. To 35-year-old president of the majority of people some white hair. With age, melanocytes gradually decreased sexual activity, the resulting pigment also be reduced, hair color fade, long out of that white hair.
Genitals aging time: 35-year-old
As the ovaries the quantity and quality of eggs began to decline, women's fertility began to decline after the age to 35. Endometrium may be thinner, making it difficult implantation of a fertilized egg, resulting in a kind of resistance to sperm environment. Male fertility is also in this age begin to decline. After the 40-year-old married man, as a result of decline in the quality of sperm are more likely to spouse abortion.
Breast aging time: 35-year-old
Middle-aged women are often strong enough for their own breasts to worry about. In fact, the woman to 35 years of age, breast tissue in the fat began to lose, volume and fullness decline. From the age of 40 onwards, women's breasts began to sag.
Skeletal aging time: 35-year-old
Children's bones grow very fast, just two years can be completely recycled. Complete regeneration of bone in adults take 10 years. Before the age of 25, bone mineral density has been increasing. To 35-year-old, bone began to drain into the natural aging process. A reduction in bone density may lead to reduced height, the middle vertebrae bone atrophy, or fragmentation.
Eye Aging Time: 40-year-old
Presbyopia of the eye than we expected, there were early, most people in the 40-year-old becomes a "presbyopia." This is because the increase with age, eye muscles become increasingly weak, ability to focus the eyes begin to decline.
Heart aging time: 40-year-old
With the increasing aging of our body, the heart pumping blood to the body's efficiency begins to lower. This is because the blood vessels gradually lose elasticity, hardening of the arteries or there is obstruction. Caused by these changes because of accumulation of fat in the coronary arteries, reducing blood delivered to the heart, and sometimes cause angina. Over the age of 45 men and 55 women over the age greater the probability of a heart attack. A new study found that the average age of the heart of the British than their actual age 5 years of age may be related to their obesity and lack of exercise related.
Dental aging time: 40-year-old
People grow old, when the amount of saliva secretion will be reduced. Saliva can kill bacteria, saliva reduction, teeth and gums more relaxed. Gums gradually shrunk in size, which is common in adults over the age of 40 conditions.
Renal failure in the old time: 50-year-old
Kidney filtration capacity started to decrease from 50-year-old. Renal blood of waste can be filtered out, the consequences of reduced renal filtration is that people have lost their function of holding back urine at night, need to go toilet many times. 75-year-old's kidney filtration volume is half the age of 30.
Prostate Aging Time: 50-year-old
The prostate often increases with age, caused by an increase in the number of issues, including urine. Benign prostatic hyperplasia, plagued more than half of the 50-year-old man. Prostate absorb a large amount of testosterone, will accelerate the growth of prostate cells, causing benign prostatic hyperplasia. Just like a normal prostate the size of walnuts, but there is an orange prostate hyperplasia so much.
Intestinal aging time: 55-year-old
If the harmful bacteria and beneficial intestinal bacteria is able to meet such a stomach is healthy. After the 55-year-old people, this often feel stomach discomfort, it is because the stomach began to aging, changes in gut environment, less suitable for the survival of beneficial bacteria, beneficial bacteria, the number is declining. This situation is particularly evident in large intestine will lead to decline in the human digestive function, intestinal disease, increased risk. As we age, stomach, liver, pancreas, small intestine of the digestive fluid flow gradually reduced, so the probability of constipation in the elderly occur much more than the young.
Ear aging time: 55-year-old
From 55-year-old started the inner ear "hair cells" begin to decrease. Hair cells, an acceptable sound vibration, and sound vibrations to the brain.
Tongue and nose aging time: 60-year-old
A person's life, initially distributed in the tongue's taste buds are about 1 million, to the old system, this number is likely to be halved. After a 60-year-old, taste and smell gradually decline, they may be due to the hole, such as nasal or sinus problems and accelerate the degradation of class.
Bladder aging time: 65-year-old
65 years old, we may lose bladder control, urinary incontinence and urinary frequency phenomenon began to appear. At this point, the bladder will suddenly shrink, even if the urine has not yet filled the bladder. Women more vulnerable to bladder problems, entering menopause, estrogen declines in urinary levels of the organization to become thinner, more weakness, bladder support function decline. If the 30-year-old when the bladder can hold two cups of urine, then the 70-year-old can only hold a cup. This will result in the number of times the toilet more frequently, especially the decline in muscle flexibility, making the urine of bladder not completely emptied, which in turn lead to urinary tract infection.
Throat aging time: 65-year-old
With age, our voices will change. This is because the throat and soft tissue weakening, affecting the extent and quality of the sound loud. At this time, women's voices become more and more hoarse, while the men's voices is increasingly weak.
The liver of aging time: 65-year-old
The liver seems to be the only body able to challenge the aging process (qiguan). The regenerative capacity of liver cells is very strong. As part of the liver after surgery, within 3 months it will grow into a full liver. If the donations do not drink Do not take drugs or not suffered from infectious diseases, then a 70-year-old liver transplant 20-year-old can be young people.
In order to prevent aging then we want to do?
1, maintaining nutritionally balanced diet;
Can give the body a balanced diet to provide adequate maintenance and updating of requirements, neither of which would also damage the human body can not be ignored, even by people hate fat, fat is to maintain skin elasticity and important constituents of brain function.
2, appropriate exercise, especially aerobic exercise;
Appropriate exercise of the heart and lung function is very important and can enhance its functions. But the heart of a vibrant quality of life assurance.
3, select the appropriate anti-oxidant products
Scientific evidence: the number of human aging and free radicals is directly related to selecting a suitable anti-oxidants, reduce the production of free radicals or eliminate the presence of some free radicals, the commonly used anti-oxidant products are: Vitamin A, vitamin C, vitamin E, Coenzyme Q10, green tea polyphenols, grape seed capsules, usually eat more fruits and vegetables, drink green tea will do. Also added collagen to maintain the elasticity of the skin, joints to maintain lubrication
