As we continue to age, the years will leave traces on our bodies, and aging is an inevitable physiological process for each of us. Many people think that the organs of our body only begin to age when they enter old age, but in fact, the organs of the human body also have a lifespan. Do you know when the organs of our body begin to age?
The human body is like a machine, and each organ is like a part, each with its own lifespan. When we are young, the normal body organs are in a good stage, and with the growth of age, the body organs will also have various "aging", and aging is divided into the gradual degenerative changes in the structure and physiological function of human organs.
Degenerative changes in organizational structure
It is usually manifested by a decrease in the number of functional cells of organs and tissues, such as the gradual atrophy of myocardial fibers, the decrease of vascular elastic fibers, the atrophy of skeletal muscles and the decrease of organic components in bones, etc., as well as changes in the shape and appearance of organs and tissues, such as loose teeth and loss, graying of hair, wrinkles in the skin, age spots, loose and lost teeth, dizziness, and gradual shortening of height.
Degeneration of physiological functions
It usually manifests as memory loss and insomnia. Aging of bones and skeletal muscles, sluggishness, decreased diastolic function, decreased stroke volume, decreased lung capacity, decreased pulmonary compensatory capacity, less oral secretions, and weakened gastrointestinal digestion, absorption and peristalsis functions.
The British "Daily Mail" has proposed a "timeline of human organ aging", which reflects that most organs have begun to gradually age before we enter old age.
Time when the lungs begin to age: about 20 years old
Lung capacity begins to decline slowly from the age of 20, and many people are prone to shortness of breath after the age of 40. This is partly because the muscles and chest that control breathing become stiff, making it difficult for the lungs to function, and some air remains in the lungs after exhalation, causing them to be out of breath.
When the brain begins to age: about 22 years old
After the age of 22, the number of nerve cells in the brain gradually decreases, and after the age of 40, the number of nerve cells decreases at an alarming rate of 10,000 per day, which may affect memory, coordination, and brain function. Therefore, after reaching a certain age, some people will have a situation where their memory is not as good as before.
Time when the skin begins to age: about 25 years old
Excluding the influence of external factors, the natural age of skin aging is around 25 years old, mainly due to the slowdown of collagen production, dead skin cells do not fall off quickly, and the amount of new skin cells produced may be slightly reduced, which leads to the appearance of wrinkles.
Time when bones begin to age: about 35 years old
Normally, our muscles are in a long cycle of growth, damage, repair, and regeneration. After the age of 35, the rate of muscle failure is greater than the growth rate, and the body's bone will gradually lose, which will gradually enter the natural aging process, and the knee joint, hip joint, spine, lumbar spine and other joints may be prone to pain, inflammation or lesions.
The heart begins to age: about 40 years old
As we age, the heart becomes less efficient at pumping blood throughout the body. Usually after the age of 40, the heart begins to age, mainly due to the accumulation of fat in the coronary arteries, the blood vessels gradually lose their elasticity, and the arteries become stiff or blocked, so the blood supply to the heart is reduced.
The human body is a high-precision machine, and long-term overload, lack of trimming and maintenance may damage our organs and lead to diseases. Therefore, young and old, do not consume your body without moderation.
