First, running at night, especially in the evening, the air quality is better and there is more oxygen in the atmosphere, which is suitable for running.
According to our biological knowledge, plants will produce a lot of oxygen at night after a day of photosynthesis. For people who want to run, the night with plenty of oxygen is the most suitable.
At night, because there is no photosynthesis of the sun, plants just breathe, consuming oxygen in the air and producing a lot of carbon dioxide gas. The air in the morning is mostly composed of carbon dioxide, which is not suitable for running.
Second, as the saying goes, a day's plan lies in the morning. For students, morning is the most energetic time of the day, and running is a waste. Let's use this time to study.
In the evening, it is likely that after a day's study, people are already very tired, and running is easy to get excited, which is more conducive to stimulating brain learning.
Third, it will be more comfortable to take a bath and sleep after running at night. For students, few people take a bath in the morning. If you run in the morning without taking a bath, you may smell of sweat all day, which is very uncomfortable and may affect other students.
Running at night will be much better. After running at night, you can take a bath after a short rest, which makes people feel refreshed. You can continue to study or sleep after taking a shower.
In my opinion, whether for students or others, running at night is better than running in the morning.
