Generally, it rains lightly and the rainfall is moderate. You can do some sports activities outdoors, such as practicing long-distance running. But be sure to pay attention to safety and choose a place with high terrain and hard ground. If you run on the highway, you should pay attention to the passing vehicles, slow down appropriately, and have a smaller stride. When you exercise outdoors in rainy days, sweat and rain will soak your clothes, so you must take off your wet clothes indoors in time after exercise, dry your whole body with a dry towel (you can take a warm bath if possible), and put on dry clothes to prevent colds. If you can drink some hot drinks with sugar and massage yourself, you will feel more comfortable. Don't change clothes when exercising in rainy days, and let the body temperature "dry" sweat and soaked clothes, which is not only easy to catch a cold, but also causes skin diseases and arthritis after a long time.
If you encounter heavy rain, rainstorm (including thunderstorm) or stormy weather, you can suspend outdoor exercise and do some appropriate activities indoors instead, such as doing gymnastics, doing some flexibility exercises, practicing waist and abdomen strength, practicing Tai Ji Chuan's basic skills and running in situ. You can also jump and run in time. If there are stairs or corridors, you can jump rope, run stairs, jump stairs and steps. These exercises can also achieve the purpose of exercise.
If you encounter heavy rain during exercise and there is no place to escape, don't stop at this time. You can continue to move in the rain, increase your body heat, resist the cold, and run quickly to your residence. If you encounter heavy rain in swimming, you should swim to the shore as soon as possible, get ashore in time and find a place to shelter from the rain. If you feel cold, you can keep playing while sheltering from the rain.
