Why do so many people wake up at 3 am, and can’t go back to sleep?
Waking up at 3 am is common and often linked to stress, REM sleep disruption, poor sleep habits, or health issues such as sleep apnoea, low blood sugar, or anxiety. Experts suggest a regular sleep routine, avoiding screens and stimulants, managing stress, and a restful environment. Persistent awakenings may require medical attention or a sleep study.
