This time, I will tell you why people are aging and how to prevent them from aging. The unfamiliar word telomere, active oxygen, muscle mass, etc. are related.
Three major causes of aging
First of all, the difference between aging and aging, neither is aging. In fact, aging is the accumulation of ages that occur equally, and aging is a person who looks old even at the same age.
There are three changes that occur in the body that cause aging.
The first is the reduction of telomeres. Telomeres are called coupons for life and decrease little by little with each cell division. As this decreases, the DNA becomes exposed, and when it is judged to be an abnormal cell, cell division stops. In this way, aged cells accumulate.
Senescent cells also prevent the abnormal growth of cells and prevent them from developing cancer. However, when aging cells accumulate, they cause a phenomenon called SASP, which, also known as zombie cells, causes the aging of normal surrounding cells and accelerates aging.
It grows more and more in tissues and organs, resulting in an increased risk of cancer, arteriosclerosis, dementia, and cataracts. SASP is greatly related to healthy life expectancy, and there is a gap of about 10 years between life expectancy and healthy life expectancy, but when it comes to SASP, healthy life expectancy is greatly impaired.
The second aging caused by active oxygen causes the body to rust. Reactive oxygen is always produced in human life, and it is generated as a by-product after oxygen is produced and used in the body.
Reactive oxygen species connect with various substances in the body and attack normal cells and genes. Diseases caused by active oxygen include arteriosclerosis, myocardial infarction, cerebral infarction, cancer, diabetes, and pneumonia. Reactive oxygen species damage DNA and are also a factor in reducing telomeres.
Antioxidant enzymes that oppose active oxygen decrease rapidly from the age of 40, so active oxygen cannot be completely removed from this age, and it becomes easy for it to accumulate in the body. Therefore, many people start to get old in their 40s.
The third is aging due to muscle weakness, and maintaining muscle mass is very closely related to aging prevention and healthy life expectancy. There is a disease called sarcopenia here. This is a common illness in the 40s and is said to be carried by one in four people. Two people are affected in their 80s. Also, the incidence is higher in men than in women.
Symptoms are rapid weakness of sarcopenia, and if this sarcopenia symptom continues, it becomes a state of mental and physical weakness due to aging called frail, muscle weakness, aging of appearance, impaired judgment, cognitive decline, withdrawal, etc. It will be.
How to control aging
Now, I will explain how to slow down aging and raise the healthy age, which I introduced from here.
First of all, it is important to reduce saccharification stress by not taking too much sugar. The difference between saccharification and oxidation is that saccharification is koge and oxidation is rust. Oxidation can be removed by antioxidant enzymes, but saccharification cannot be removed by enzymes, and it promotes oxidation.
When sugar binds to protein, it becomes a powerful toxic substance called AGEs, which damages capillaries. Capillaries make up 99% of the body, and if they are damaged, aging will naturally accelerate. Capillaries are only small enough for hemoglobin to pass through, so they quickly become clogged with AGEs.
Capillaries begin to decrease at once in the 40s, and 40% of the capillaries are lost in the 60s. Then, the waste products in the body cannot be collected, which causes dullness, sagging, and stains. Daily diet is important to strengthen blood vessels, and "ma (beans) go (sesame) wakame (seaweed such as wakame seaweed) and (vegetables) sa (fish) (mushrooms such as shiitake mushrooms)" It is important to keep in mind the food of.
It is also important to reduce sitting time to prevent telomere reduction. Exercise can help you stretch telomeres, but it's hard because research has hurdles such as having to run 5 days a week for 40 minutes, but just reducing sitting can help.
It is said that sitting down has an adverse effect on capillaries, and that 70% of people who sit down have poor blood flow. If you keep sitting, active oxygen will accumulate in the pelvis and cause inflammation. As a result, sex hormones are reduced and women have a negative effect on the uterus.
Meditation extends your lifespan! ??
Finally, meditation has been shown to lengthen telomeres. Studies have shown that meditation activates the enzyme telomerase, which prolongs telomeres. However, rather than meditation directly extending telomeres, the stress-relieving effects of meditation may be the direct cause of telomere extension. Chronic stress is a factor in reducing telomeres.
Meditation helps to improve blood flow throughout the body as it regulates the autonomic nerves. The method of meditation is abdominal breathing meditation, which involves focusing on breathing, slowly inhaling for 5 seconds, and slowly exhaling for 10 seconds, all you have to do for 5 minutes. And the consciousness is directed to something other than your own thoughts. It's very easy, so why not try it while you're in the bathtub?
