Postprandial Somnolence

Postprandial Somnolence

Post-prandial somnolence (colloquially known as The Itis or a food coma) is a normal state of drowsiness or lassitude following a meal. Post-prandial somnolence has two components – a general state of low energy related to activation of the parasympathetic nervous system in response to mass in the gastrointestinal tract, and a specific state of sleepiness caused by hormonal and neurochemical changes related to the rate at which glucose enters the bloodstream and its downstream effects on amino acid transport in the central nervous system.

Famous quotes containing the word somnolence:

    The morning, which is the most memorable season of the day, is the awakening hour. Then there is least somnolence in us; and for an hour, at least, some part of us awakes which slumbers all the rest of the day and night.
    Henry David Thoreau (1817–1862)
