Question: Some people like to get up and exercise before dawn, which is healthy.
First, there are many benefits.
B, not necessarily beneficial
Correct answer: Not necessarily beneficial.
Analysis: Premature exercise may not be good for your health. When the sun didn't rise or just rose in the morning, the photosynthesis of plants was insufficient, the oxygen concentration was low, and the air quality was poor after a night of waste gas accumulation. If you want to exercise in the morning, it is recommended to give priority to moderate exercise instead of strenuous exercise.
Strenuous exercise in the morning is easy to excite sympathetic nerves, which will cause a series of changes in the body and affect the mental state of the whole day, which is harmful to health.
In addition, human blood sugar is at a low level in the morning, and exercise consumes a lot of blood sugar, which is prone to hypoglycemia. In addition, many people like to exercise on an empty stomach in the morning, which will stimulate the body more strongly and easily lead to abnormal blood pressure and cardiovascular diseases.
