Eating before bed isn’t always bad, but a big, rich or spicy meal close to bedtime can disturb sleep and trigger heartburn. The NHS advises people with heartburn not to eat within 3 to 4 hours of bed. If you’re hungry, a small, light snack is fine. Finish your main meal 2 to 3 hours before bed.
Below: how late eating affects sleep, the best and worst bedtime snacks, eating before bed and weight, and tips for late shifts.
How late eating affects sleep
A study of healthy adults found eating more close to bedtime was linked to poorer sleep quality, including taking longer to fall asleep and waking more in the night. Large meals keep your digestive system busy, and lying down soon after can push stomach acid up, causing heartburn. Alcohol and caffeine with a late meal make things worse.

Eating before bed and weight
What and how much you eat across the day matters more than the exact time. But late-night snacking often adds extra calories, especially in front of a screen, and poor sleep increases hunger the next day. If you’re snacking late out of habit or tiredness, an earlier bedtime can help. See menopause weight gain and revenge bedtime procrastination.
If you work late or eat late
- Eat your main meal earlier, such as at lunchtime, and have a lighter evening meal.
- Keep late meals small and easy to digest.
- Sit upright for a while after eating if you get heartburn.
- On night shifts, plan meals around your sleep. See shift work and sleep.
