Why we sleepy after eating? Rest & Digest; Postprandial somnolence

Postprandial Somnolence: Commonly known as "food coma," it's the drowsy feeling one gets after eating, especially after large meals. Blood Redistribution: After eating, increased blood flow is directed towards the digestive system, potentially causing decreased blood flow to other organs. Yet, this isn't the primary reason for post-meal sleepiness. Tryptophan & Serotonin: Consuming carbohydrate-rich foods can lead to an increase in blood tryptophan levels, which crosses the blood-brain barrier and gets converted to serotonin—a neurotransmitter inducing relaxation. From Serotonin to Melatonin: Serotonin can be further converted to melatonin in the brain. Melatonin is the primary hormone responsible for regulating our sleep-wake cycle, leading to feelings of sleepiness. The Dopamine Connection: The intake of glucose-rich foods stimulates dopamine production in the brain, providing a short-lived pleasure and often resulting in cravings for more sugary foods. Parasympathetic Nervous System: The act of eating and the presence of food in the stomach activate the parasympathetic nervous system—commonly referred to as the "rest and digest" system—leading to relaxation. Sugar Crash: The rapid spike and subsequent drop in blood glucose levels after consuming carbohydrate-rich foods can lead to feelings of weakness and fatigue, known as hypoglycemia. Tryptophan-rich Foods: Foods such as turkey, cheese, chicken, and nuts are high in tryptophan. They may lead to prolonged feelings of relaxation and satiety, making one feel sleepier after consumption. Comparing Carbs & Tryptophan: While carbohydrate-rich foods offer a quick pleasure hit due to dopamine stimulation, tryptophan-rich foods offer a longer-lasting satisfaction and satiety. Beyond Food Coma: While postprandial somnolence is a real phenomenon, the human body has multiple mechanisms ensuring vital organs, like the brain, receive adequate resources even after a large meal.
