Finish Eating 2–3 Hours Before Bed for Sleep

Key takeaway

Often stop large meals about 2–3 hours before bed; eating very late can disrupt sleep for some people, but the ideal gap varies.

  • Heavy food near bedtime can keep core temperature and digestion elevated.
  • Aim for about 2–3 hours between a substantial meal and lights-out.
