Because exercise before going to bed excites the brain, which is not conducive to improving sleep quality.
Recently, Japanese scholars believe that exercise before going to bed can promote the quality of sleep. Experiments show that people's sleep quality is closely related to rectal temperature. The faster the rectal temperature drops, the easier it is for people to fall into deep sleep. Studies have found that doing some light exercise such as jogging before going to bed can promote the temperature rise. When the body is slightly sweaty after jogging (this exercise time varies from person to person, generally speaking, 20-30 minutes is appropriate), then stop. At this time, the body temperature began to drop. When sleeping after 30-40 minutes, people will easily fall into deep sleep, thus improving the quality of sleep.
Nowadays, many professional athletes like to do massage before going to bed, which proves the reliability of this view psychologically and physically. The popular folk saying "take a hot bath (feet) before going to bed and have a comfortable sleep" also accords with this new view.
Therefore, you have to wait at least one hour before you can go to bed after exercise!
