Scientists have found that 3: 00 to 6: 00 pm is the most suitable prime time for exercise in the human physiological cycle, because under the command of the rhythm of the brain physiological cycle, at this time, the human body temperature is at the highest point, the muscles are the warmest and most elastic, and people are quick-witted, strong and not easy to get hurt, while the pulse beat and blood pressure are the lowest. The average person's body temperature is the highest from 2 pm to 4 pm, and then it begins to drop. On the contrary, the body temperature is the lowest within 3 hours before getting up in the morning. If you exercise, you can't achieve the best results.

However, health experts believe that there is no need to worry about the difference in body temperature, and it is more important to seize the time you can allocate to exercise. The American Sports Association makes the following suggestions for athletes:

If morning exercisers like to exercise in the morning, they'd better stick to it, not after work, because obviously you are a person who will be held back by work and can't find time to exercise. You need to pay attention to do enough stretching and warm-up exercise before exercise, because the body temperature is still low in the morning, which is easy to get hurt and is not good for the heart and blood vessels; From the perspective of physiological science, afternoon exercisers undoubtedly have the best opportunity, the best physical response and the softest muscles. Relax your family. If exercise is to relieve stress, it is appropriate to do relaxing exercise at any time. Night owls try to exercise 3 hours before going to bed. Exercise too close to bedtime may be bad for the heart, or it may be difficult to sleep because of excitement.
