What should I avoid before bedtime?
Common sleep disruptors
Caffeine is a stimulant that can stay in your system for 6–8 hours, so a late afternoon coffee or tea may keep you awake. Alcohol may help you fall asleep faster, but it often fragments sleep later in the night. Heavy or spicy meals close to bedtime can cause indigestion and make it hard to get comfortable.
Nicotine is another stimulant that can disrupt sleep, so avoiding it before bed is wise. Intense exercise within an hour of bedtime can also be too activating for some people, though for others it’s fine. Pay attention to how your body responds.
- Caffeine (coffee, tea, soda, chocolate) after mid-afternoon
- Alcohol within 3 hours of bed
- Large, fatty, or spicy meals within 2–3 hours of bed
- Screens with bright blue light (phones, tablets, laptops)
- Stressful conversations, work emails, or intense arguments
What to do instead
Replace these habits with calming activities that signal to your brain that it’s time to wind down. Reading a physical book, gentle stretching, or listening to quiet music can help. Keep lights dim and the room cool.
If you’re hungry, a light snack like a banana or a small bowl of cereal is fine. Just avoid anything that’s heavy or sugary. The goal is to make the transition to sleep as smooth as possible.
Common mistakes
- Thinking a nightcap helps sleep—alcohol may speed up sleep onset but worsens sleep quality.
- Assuming all screen time is equally bad—passive TV might be less disruptive than interactive scrolling, but both can delay sleep.
- Ignoring personal sensitivity—some people can drink coffee at 6 p.m. and sleep fine, while others can’t.
