Don't do morning exercises on an empty stomach or full stomach.
You'd better eat something before morning exercise. Do not exercise on an empty stomach or a full stomach. It's best to have a rest after half-fullness, and then go outdoors for morning exercise.
It's not too early to do morning exercises.
Some people get up at three or four in the morning to exercise, and then continue to sleep, which is not only easy to inhale polluted air, but also makes the biological clock disorder, leading to fatigue and premature aging. It's best to wait until the sun comes out before starting morning exercise, because the air pollution on the ground is the heaviest before sunrise, and there is less oxygen at this time. After sunrise, green plants start photosynthesis, inhale carbon dioxide and exhale oxygen, and the air will be fresh.
The temperature is too low to do morning exercises.
In autumn and winter, the temperature is too low or the temperature drops suddenly, which is not suitable for morning exercise, especially for the elderly and infirm, who have poor body temperature regulation ability and are prone to catch a cold.
Avoid practicing in the forest in the morning on rainy days.
In rainy weather, many people insist on doing morning exercises, but it is not suitable for doing morning exercises in the Woods, because at this time, although trees can not be exposed to sunlight, they are still absorbing oxygen and discharging carbon dioxide. At this time, it is easy for people to inhale too much carbon dioxide and cause poisoning.
Not suitable for morning exercise in rainy and foggy weather.
The current "fog" is different from the previous "water mist". Because of the serious pollution, it is mostly "pollution fog". Tiny droplets contain a lot of pollutants and pathogenic bacteria. When the amount of breathing increases in the morning exercise, more pollutants will be inhaled, which will cause dyspnea, chest tightness, palpitations and so on in severe cases.
