As a national fitness promotion, "walking" is the safest way to exercise, and it is best to walk for 30 minutes every day. Walking can regulate immunity, improve disease resistance and speed up recovery after illness. People who are not used to exercise at ordinary times and seldom exercise should avoid excessive exercise at first, and the exercise time should not exceed 2 hours.

2. Yoga

Thymus is the center of cellular immunity in vivo, located in the thoracic mediastinum. Its main function is to regulate the proportion of T lymphocytes and secrete thymosin, so that the body can maintain cellular immune function and kill foreign bacteria. Many postures and breathing methods of yoga can stimulate the thymus, and improve the body's immune ability by stimulating the secretion of the thymus.

Step 3 swim

Swimming in winter can improve the body's adaptability to cold, stimulate and promote blood circulation and metabolism, improve the sensitivity of body temperature regulation, and enhance the body's adaptability to external cold and hot temperature changes.

Extended data:

The University of Toronto requires ordinary people aged 19-29 who don't exercise regularly to do 40-minute aerobic exercise three to five times a week for 12 weeks. From the blood test, it was found that the killer cells of CD 16 increased by 27% for people who exercised three times a week, but only increased by 2 1% for people who exercised five times a week, while the number of immune cells decreased by 33% for people who exercised three times a week, but there was no change.

Therefore, although exercise can lose weight and improve heart and lung function, it is the best way to prevent heart aging, but excessive exercise is not appropriate. As long as you insist on 30 minutes of aerobic exercise three times a week, you can achieve healthy results.
