Understanding Post-Meal Sleepiness

The video explains why people feel sleepy after consuming large meals, such as a Thanksgiving dinner. It highlights the role of tryptophan, an amino acid found in turkey, which is converted into serotonin and melatonin in the brain, promoting sleepiness. However, the amount of tryptophan in turkey is not enough to cause a food coma on its own. Other foods like beef, chicken, cheddar cheese, and egg whites also contain tryptophan. Additionally, the large quantity of food consumed requires increased blood flow to the stomach for digestion, reducing blood flow to the brain and causing tiredness. Stress from holidays and family gatherings can also contribute to this sleepiness.
