Why You Feel Sleepy After Eating

Have you ever noticed how sleepy people get after a big meal—especially during the holidays? One moment everyone’s laughing around the table, and the next, half the group has vanished to find a cozy corner for a quick nap. It got me wondering: Why does eating make us so tired? So I did a little digging, and here’s what I found.

Feeling sleepy after eating—often called postprandial somnolence or the classic “food coma”—is a common experience, and it’s caused by a mix of biological and nutritional factors. Here’s what they say is really going on:


1.) Blood Sugar Fluctuations

  • Meals high in refined carbohydrates (like white bread, pasta, or sugary snacks) cause a rapid spike in blood sugar.

  • Your body releases insulin to bring it back down, and that crash can leave you feeling sluggish.


2.) Tryptophan & Serotonin

  • Foods like turkey, milk, eggs, and nuts contain tryptophan, an amino acid that helps produce serotonin, which regulates mood and sleep.

  • A meal rich in protein and carbs can increase serotonin levels, making you feel drowsy.


3.) Melatonin-Rich Foods

  • Some foods naturally contain melatonin, the sleep hormone—like tart cherries, oats, rice, and pistachios.

  • These can subtly signal your body to wind down.


4.) Large Meal Volume

  • Eating a big meal diverts energy to digestion. Your body focuses on breaking down food, which can leave you feeling tired.


5.) Circadian Rhythm

  • Many people experience a natural dip in energy in the early afternoon. Eating during this time can amplify the effect.
