You might’ve heard that the reason people get sleepy after eating is because their bodies redirect blood from their brains to their digestive tracts, but scientific evidence has debunked this myth. Post-meal drowsiness is actually the combined result of several body processes and behaviors, and while you may not be able to avoid it completely, you can take steps to minimise it.

Feeling sleepy after eating (post-prandial somnolence) is common and can be triggered by large meals, high-carb or high-fat foods, or rapid blood-sugar fluctuations. The timing of meals and your body’s natural circadian rhythms can also play a role in post-meal sleepiness, especially during the “afternoon slump”.

Underlying health issues, such as sleep apnoea, insulin resistance, anaemia, or thyroid disorders, may contribute to excessive tiredness after eating and warrant medical evaluation. To counteract post-meal fatigue, eat smaller, balanced meals high in fibre and protein; stay hydrated; and follow with a light walk or sun exposure.
