Stress and a busy mind
Overthinking and worry keep the brain alert and the fight or flight system active which blocks sleep onset and causes midnight wake ups. Write a to do list early evening and use a 15 minute wind down to shift the mind into rest mode. Cognitive behavioral therapy for insomnia teaches these skills and is the first line treatment.​

Some antidepressants, beta blockers, diuretics, steroids, and late stimulants can disrupt sleep or cause frequent urination. Ask the doctor about dose timing or alternatives if sleep got worse after a medicine change.​

Too much time in bed
Going to bed early to catch up and staying in bed awake trains the brain to link bed with wakefulness. Keep a strict sleep window based on your average sleep time and only go to bed when sleepy. This is part of cognitive behavioral therapy for insomnia and it works.​

Naps and evening workouts
Long naps reduce sleep pressure and very late heavy workouts can delay sleep. Keep naps short under 20 minutes before 3 PM and finish hard exercise at least four hours before bed.

Caffeine, nicotine, and alcohol
Caffeine and nicotine are stimulants that can delay sleep and reduce deep sleep for hours while alcohol can fragment sleep later in the night. Stop caffeine and nicotine at least six hours before bed and skip nightcaps if you wake at 2 AM.​
