INTRODUCTION
This article explains how late-night snacking can affect sleep and what types of food are better choices before bed.
ARTICLE (ALL LEVELS)
Many people enjoy a late-night snack. However, eating before bed can affect sleep.
The body follows a natural cycle called the circadian rhythm. In the evening, it releases melatonin to prepare for sleep. Eating late can suppress melatonin and make it harder to fall asleep.
Lying down after eating can also cause heartburn or bloating because digestion slows at night.
DEVELOPED ARTICLE (B1–C2)
Experts suggest leaving about three hours between eating and going to sleep. This allows the body to complete digestion and return to a restful state.
If you crave a snack, it is better to choose light foods. Items containing tryptophan — an amino acid — may support sleep because the body uses it to produce melatonin and serotonin.
Foods like pistachios and pumpkin seeds may help, but overall, avoiding heavy late-night eating can improve sleep quality and overall health.
