Why do teens stay up late?

Teens often stay up late due to a combination of biological, social, and lifestyle factors. Their circadian rhythms shift during adolescence, making them naturally inclined to feel more awake in the evening. Additionally, social activities, homework, and screen time can contribute to late nights, as many teens prioritize socializing or using electronic devices over sleep. The pressure of academic responsibilities can also lead them to sacrifice sleep for studying or completing assignments.
