Proper exercise in late spring is better for defense?

During the cold spring, the temperature often drops suddenly, and the sudden cold spring can easily make people uncomfortable, especially middle-aged and elderly people with chronic diseases and people with poor physical fitness, which need to be dealt with well. According to health experts, in the cold season, in addition to paying attention to cold and warmth, you can actually carry out appropriate physical exercise, which has better defense effect, so let's understand.

Health experts point out that spring is a good time to carry out physical exercise, such as playing Tai Ji Chuan, doing aerobics, flying kites, hiking and other aerobic outdoor activities, which can effectively enhance the body's immunity and disease resistance. At the same time, outdoor activities can also make people breathe fresh air, improve heart and lung function, and make the body adjust better to adapt to the changeable climate in spring.

However, in the cold weather like late spring, if you want to go out for exercise, you'd better "stay in the sun" and avoid exercising in the morning and evening when the temperature is low or it's raining and snowing. It's too early. It's when the humidity is high and the temperature is low, many bacteria are in an active breeding period in spring, and they diffuse in the air. They start exercising before the sun comes out, and the photosynthesis of plants has not started, and the oxygen content is very low. To sum up, exercising in the morning does more harm than good. When you go out for exercise at night, the oxygen content is the same as that in the morning, but the dust index becomes higher due to exhaust emissions.

In addition, exercise time and intensity should be paid attention to during the cold spring, and slow-paced and moderate exercise methods are more suitable, such as Tai Chi, mountain climbing and flying kites mentioned above. The temperature is still cold in spring, and people's muscles and ligaments are stiff. If they are not fully prepared before exercise, they are prone to sprains. Warm-up activities can be fast or slow, which can exercise the whole body and accelerate blood circulation. Remember to eat properly before exercise. Fasting exercise may bring dizziness, sweating and other hypoglycemia symptoms. You can drink porridge properly before exercise, replenish water, and have moderate calorie intake.

Precautions for cold exercise in late spring 1. Warm up before exercise, start slowly and gradually increase the intensity; After exercise, there should also be a few minutes of relaxation exercise. 2. Choose suitable sports shoes, and the shoes with elastic anti-slip effect are better; Choose a flat and cool sports ground. 3. It is not advisable to exercise within one hour before and after eating. 4. If there is any discomfort during exercise, such as dizziness, chest pain, palpitation and night sweats, stop exercising immediately. 5. Patients with chronic diseases such as hypertension, heart disease and diabetes, as well as those with individual health problems such as waist, shoulder and neck pain and acute sprain of hands and feet, should be examined by a professional doctor and evaluated by a doctor, and then choose the appropriate type and intensity of exercise.
