Remember: never run as soon as you get up. I suggest you do exercise at seven o'clock. Don't get up too early. It is best not to exercise in bad weather. Exercise time varies from person to person
When I first got up in the morning, the operation of various organs of the human body was still at a low level. At this time, exercise is more dangerous for people with fragile cardiovascular function. Sports medicine has proved that running early increases the possibility of vascular thrombosis and easily leads to vascular embolism, because the blood cohesion is improved by 6%. In addition, the increase and acceleration of blood pressure and heart rate are large, which is easy to overload and affect the exercise effect and health.
