It's bad for your health to exercise too early.
As the saying goes, "a day's plan lies in the morning", many people get up before dawn to exercise, thinking that after exercising their bones and muscles, they can promote blood circulation, strengthen their physique and prepare for a busy day. In fact, premature exercise is not good for your health. Cheng Jiehui, director of the Center for Prevention of Diseases in Zhuhai Hospital of Guangdong Provincial Hospital of Traditional Chinese Medicine, pointed out that human blood pressure reached its first peak at 6 am to 8 am. Exercise increases heart load and raises blood pressure, especially for patients with hypertension and cardiovascular and cerebrovascular diseases. It is not appropriate to do physical exercise too early.
In the morning, the sun has not risen or just risen, the photosynthesis of plants is insufficient, the oxygen concentration is relatively low, and the air quality is relatively poor after a night of urban waste gas accumulation. It is recommended that you exercise after the sun rises. In addition, the human body's yang rises in the morning, and the yang at this time is still very delicate. Traditional Chinese medicine believes that "movement leads to yang rising", and the more intense the exercise, the more severe the human body's yang is, which is not conducive to the rest of yang. Therefore, it is suggested that morning exercise should be mainly moderate exercise, such as walking, jogging, morning exercise and Tai Ji Chuan. And strenuous exercise is not appropriate.
Is breakfast good before exercise or after exercise? In this regard, Cheng Jiehui pointed out that the blood sugar level is low on an empty stomach in the morning. At this time, exercise, especially strenuous exercise, increases energy consumption and easily leads to hypoglycemia symptoms, such as dizziness, chest tightness, palpitation, sweating, fatigue and even syncope. But after breakfast, the gastrointestinal tract enters digestive mode. If you exercise immediately, it will affect digestion and be bad for your health. Many people will struggle with "whether it is better to have breakfast before exercise or after exercise". Since exercise needs an energy source, it is definitely best to eat breakfast first. As mentioned above, it is not advisable to exercise too early in the morning. If you get up early, eat breakfast first, and then exercise half an hour or 1 hour after dinner to see the digestion.
Not sleeping at noon will consume your energy.
So is noon suitable for exercise?
Dr Cheng Jiehui, director of Chinese medicine, believes that Chinese medicine advocates taking a nap, that is, taking a rest at noon. Noon is 1 1 to afternoon 13. During this period, yang is the most abundant and yin is born. The transition of yin and yang is the time of combining yang. Taking a lunch break can make a smooth transition between yin and yang, so it is recommended to take a nap. Taking a nap can nourish yang, restore physical strength and provide energy supply for work and study in the afternoon. If you exercise without sleeping at noon, you will inevitably consume energy and yang, which will affect your mental state in the afternoon and be harmful to your health over time.
Exercise at night "see a doctor if you are not sick"?
For office workers, they can only exercise at night, but I heard that "exercising at night means not getting sick and seeing a doctor", right?
Cheng Jiehui introduced that many friends often choose to exercise at night because they are busy during the day. Housewives have nothing to do after dinner and often go to the square dance. As the folk proverb says, "Work at sunrise and rest at sunset." Exercise at night, especially strenuous exercise, is really bad for health and pranayama. Chinese medicine believes that when the sun goes down at night, the yang of the human body gradually converges and hides, and gradually enters the sleep stage. The so-called "Yang enters Yin and then sleeps". Exercise at night stimulates the body's yang, especially strenuous exercise, which is easy to cause insomnia. Therefore, exercise at night not only damages the yang, but also consumes the yin essence, which is not good for the health in the long run. "This is equivalent to the machine after a day of operation, has been in a state of tension. Don't stop for maintenance at night, but increase horsepower to continue running. This price can only be repaired or scrapped in advance. "
Then, is it appropriate to take appropriate activities after meals, such as walking? Cheng Jiehui believes that taking a walk after meals can promote gastrointestinal peristalsis, improve digestive function, calm the nerves and help sleep. Just grasp the intensity of the activity, not too intense.
Office workers should choose afternoon and evening exercise.
For working people, they don't have time to go to work during the day and don't advocate exercise at night, so when is the right time to exercise? Cheng Jiehui pointed out that in fact, the prime time for exercise in a day is 16: 00- 17: 00 in the afternoon, because after most of the day's daily work, the muscles and ligaments of the human body have been fully active, and the heart rate and blood pressure tend to be stable, so you can carry out more intense aerobic exercise, such as running, playing ball, swimming, equipment fitness and so on.
But the afternoon 16: 00- 17: 00 is still working time, so it is impossible to exercise at this time. Therefore, it is suggested that the working class can postpone it to 17: 30- 18: 30. This time is afternoon and evening. The sun has not set yet, and it is still in season. At this time, exercise not only avoids working hours, but also does not affect the collection of the spirit of the sun after sunset, and there is no conflict with dinner time, which is more suitable for working people.
