With the aging of China society, everyone will turn pale when talking about "old". In fact, aging is a natural law, not so terrible. The key is to know how to keep in good health and let yourself grow old with dignity.

Experts from the China Geriatrics Association believe that longevity should pay attention to health care tips and summarize 7 health care tips to share with you:

First, peace of mind. My investigation found that 90% of centenarians in Lingao, Hainan are peaceful and like to let nature take its course. Sun Fuling, vice chairman of China People's Political Consultative Conference, said: "Peace of mind is the basis of longevity."

Second, drink tea in moderation. Tea is rich in antioxidants (polyphenols), which helps the human body to resist heart disease, cancer and premature aging.

3. Moderate activities. Most of the 30 centenarians interviewed still do housework and farm work every day.

Fourth, eat fruits and vegetables and nuts. Fruits and vegetables contain a lot of vitamins and antioxidants, which can improve the function of immune system and avoid premature aging. Studies have shown that walnuts are the healthiest nuts, contain the most powerful antioxidants, and can resist diseases and aging. Old people can benefit from eating 3-4 walnuts every day.

Fifth, get more sunshine. Studies have found that vitamin D deficiency increases the risk of fatal diseases, and vitamin D is formed by sunlight.

Sixth, sing often. Studies have shown that frequent singing can reduce stress, promote heart health and prevent depression in the elderly.

Seven, make friends. Studies have found that establishing close friendship and family relationships is one of the secrets of longevity and health.

The above seven health-preserving secrets are the secrets to guide the health and longevity of the elderly, which are worth collecting and sharing. I hope everyone can grow old with dignity and live a happy old age.
