¿Es normal sentir sueño después de comer? Lo que dice la biología
Aunque pueda parecer solo un efecto del exceso de comida, la realidad es que detrás de esta sensación hay procesos biológicos bien estudiados que afectan al sistema nervioso, a las hormonas y al metabolismo.
TL;DR
- Postprandial somnolence, or sleepiness after eating, is a well-studied biological process.
- Digestion requires energy, activating the parasympathetic nervous system which leads to relaxation and sleep.
- Meals high in carbohydrates and fats can cause blood glucose fluctuations, leading to fatigue.
- Foods containing tryptophan can increase serotonin and melatonin, promoting sleepiness.
- Natural dips in alertness during midday and afternoon can intensify post-meal sleepiness.
- Extreme or persistent sleepiness after eating may indicate metabolic or digestive issues.
- Managing portions, balancing macronutrients, and light activity after meals can help reduce fatigue.
