Question

Which one can prevent a good night sleep? Going to bed at the same time, going to bed only when you tired, getting regular exercise at least several hours before your bedtime, or the intake of caffeine and alcohol?

Answer 1

The intake of caffeine and alcohol can prevent a good night's sleep. Caffeine is a stimulant that can interfere with your ability to fall asleep and reduce sleep quality, while alcohol may initially make you feel drowsy but can disrupt your sleep cycle and lead to poor sleep quality later in the night. The other options—going to bed at the same time, only going to bed when tired, and getting regular exercise—are generally positive habits that can promote better sleep.
