Good sleep can significantly increase the number of two kinds of immune cells in the body, while lack of sleep will reduce the function of the immune system and increase the chance of illness. The cold weather in autumn is a season of frequent diseases, so sleep time should be increased by one hour to let the immune system recover from busyness and fatigue, and wake up the next morning feeling refreshed.

2. Wash your hands several times a day.

Scientific research has found that cold viruses can survive for two hours on hands and 72 hours on hard surfaces. When a person with a cold touches his nose, he catches a cold virus on his hand and carries it everywhere. Frequent hand washing can minimize the risk of respiratory tract infection and influenza, but you can't expect to kill bacteria once and for all by washing your hands with soap, you can only rinse them off one by one.

3. Massage three acupoints

Stimulating three acupoints can improve local blood circulation, prevent inflammation in autumn and improve immunity. They are Dazhui point (below the most prominent vertebra behind the neck when lowering the head), Quchi point (the outer end of the elbow transverse stripe formed by bending the elbow at right angles, and then moving outward 1.5 inch), and Fengmen point (Dazhui point moves two joints downward, and then moves one and a half fingers left and right). You can press and rub each acupoint with your middle finger for two to three minutes.

4. Regular moderate exercise.
