Why Do We Feel Sleepy After Eating?
Digestion and Blood Sugar Levels
-
Digestion Requires Energy: After eating, the body uses energy to digest food. This is more demanding if the meal is rich in fats and heavy ingredients.
-
Blood Sugar Fluctuations: High-carb or sugary foods can cause a spike in blood glucose followed by a crash, leading to fatigue and drowsiness.
The Role of Hormones
-
Insulin: This hormone helps transport glucose into cells. Excess insulin can cause a rapid drop in blood sugar, triggering tiredness.
-
Serotonin and Melatonin: Carbohydrates increase the production of these hormones, which play roles in relaxation and sleep regulation.
Meal Size and Timing
-
Large Portions: Consuming too much food puts extra strain on the digestive system, which may lead to tiredness.
-
Late Meals: Eating late at night disrupts the body's natural rhythm and increases sleepiness.

Carbohydrates: Bread, pasta, rice

Sugary Foods: Cakes, pastries, desserts
