1. Regular gentle exercise
The susceptible diseases in cold weather are all related to heart and lung. Heart and lung health can reduce the incidence rate in autumn and winter. Appropriate moderate intensity exercise can improve cardiopulmonary function and enhance human immunity. Moderate exercise refers to reaching 60% to 70% of the maximum heart rate (220 minus one's own age) at the center of exercise. For example, a 25-year-old person's maximum heart rate is 220-25=195, and his heart rate should be controlled at 195 during exercise × 60% to 195 × 70%, i.e. between 117 and 137. The sports recommended by fitness experts are walking, swimming, and jogging.
