Personally, I think it is better to run at 5-7 pm in autumn and winter, because it is cold in autumn and winter and the temperature is low and humidity is high in the morning. It is easy to get sick after running and sweating. Relatively speaking, it is not recommended to run in the morning, because the legs are cold and the body is cold. Running in spring and summer can be around 7- 10 in the morning and 4-8 in the afternoon. Morning running can effectively awaken the dormant body, stimulate vitality, consume fat, and make the whole day full of vitality. Morning running can also exercise your good habit of getting up early. But don't run on an empty stomach in the morning run, eat less food and add a little sugar to prevent hypoglycemia from causing fainting. Running in the afternoon is friendly to most office workers, which can fully release the stress of the day and make the human body metabolize faster in the afternoon. At this time, running helps to lose weight and help sleep.

Of course, what suits you is the best. You should actively adjust the running mode and time, control the running intensity and make a long-term running plan according to your own schedule. Don't fish for three days and dry the net for two days. Remember to stretch before and after running.
