The short explanation
Late-night phone use is one of the most common reasons young adults sleep poorly. The light and the constant stream of content keep the brain alert, and staying up late shifts the body clock. A short or broken night then makes mood lower, patience shorter and concentration weaker the next day, which can lead to more scrolling the next night. Some people scroll late because they feel anxious, low or lonely and the phone is a distraction. If cutting back does not help, or if the low mood continues even after better sleep, it is worth talking to a counsellor or doctor.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Practical steps that help many people include keeping the phone out of reach in bed, setting a fixed wake time even on weekends, getting daylight in the morning, and avoiding caffeine in the evening.
- Signs of something more than poor sleep habits include low mood most days, losing interest in things, anxiety that keeps you awake, or thoughts that life is not worth it.
- Energy drinks and late-night snacking can also disturb sleep.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell whether poor sleep is the cause of your low mood or a sign of anxiety or depression. A counsellor or doctor can help work that out.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Could my mood be low mainly because of poor sleep?
- Could anxiety or depression be keeping me up?
- What sleep routine would help me?
