Postprandial somnolence, commonly known as sleepiness after eating, is a prevalent experience characterized by an overwhelming desire to sleep following a meal. It affects individuals of all ages, impacting their productivity, alertness, and overall well-being.
The causes of postprandial somnolence are multifaceted, involving physiological, dietary, and lifestyle factors. A primary contributor is the release of insulin in response to food intake, which promotes the uptake of glucose into cells throughout the body, including the brain. This influx of glucose can lead to a temporary decrease in brain activity, resulting in drowsiness.
