You can start at six in the morning. There is too much time for a nap. A nap of 30 minutes to an hour is enough. It is best to sleep at eleven o'clock at night, and take a bath before going to bed, which can be adjusted according to the season. Maintaining good and healthy living habits is very useful for college students now, which can maintain a good mental state, study better and cultivate good personal qualities. Nowadays, college students generally have irregular lives and low physical fitness. You must seize these years and make all-round progress in your study and life!

Good luck!
