Foods to Avoid Before Sleep for Better Night Rest

Introduction

What you eat at night directly affects how well you sleep. Certain foods to avoid before sleep can cause digestion problems, raise stress hormones, or stimulate the brain. Even healthy foods can hurt sleep if eaten too late.

This guide explains which foods disturb sleep, why they do so, and what happens in your body when you eat them at night.

Why Food Matters Before Sleep

Before sleep, your body shifts into rest and repair mode. Heavy, sugary, or stimulating foods force your body to stay active instead of relaxing.

Eating the wrong foods at night can:

• Delay falling asleep
• Reduce deep sleep
• Cause night waking
• Increase heartburn or discomfort

Foods to Avoid Before Sleep

Caffeinated Foods and Drinks

Caffeine stays in the body for up to 8 hours.

Avoid:

• Coffee
• Energy drinks

• Coffee-flavored desserts

Even small amounts can reduce deep sleep.

Sugary Foods

Sugar causes blood sugar spikes and crashes, leading to early waking.

Avoid:

• Candy
• Ice cream
• Cakes
• Cookies
• Sweet cereals

Sugar increases nighttime alertness.

Spicy Foods

Spicy foods irritate digestion and raise body temperature.

Avoid:

• Chili
• Hot sauce
• Spicy curries

These can cause heartburn and restless sleep.

Heavy and Fatty Foods

High-fat foods take longer to digest.

Avoid:

• Pizza

Poor digestion can wake you during the night.
