1. Keep warm properly.
Many people will put on light clothes before exercise and even start running outside in sleeveless sportswear, but this is actually inappropriate. Before exercise, when the body is not hot, if you wear too thin clothes, it will easily have adverse effects on the lungs and bronchi. Clothes should be added or subtracted during exercise, not before exercise.
2. Add warm water before exercise.
The best time to drink warm water is 2 hours before exercise. Supplementing warm water 2 hours in advance can give the kidneys enough time to adjust the body fluid balance and osmotic pressure to the best state. Drinking warm water before exercise can not only improve the body's heat regulation function, but also reduce the heart rate during exercise. Remember, you can't use hot coffee or hot cocoa instead of warm water, which will not achieve the effect and will only make your water lose faster!
3. do warm-up exercises.
Warm-up exercise before exercise is absolutely essential! You can do jogging, * * *, stretching and so on. Make muscles in all parts of the body fully active, and then start to engage in high-intensity exercise. Especially before swimming in the water in winter, you must do a good job of warm-up and let your body heat up first to avoid cramps.
4. Use the correct breathing method
It is best not to take a big breath during exercise, and try to take "breathing through the nose" to reduce the adverse effects of cold air on the respiratory tract. With the increase of exercise, you can use your mouth to help inhale.
