Post-Lunch Sleepiness: Why it Happens and How to Control It, Expert Reveals

• Post-lunch sleepiness is linked to the body's circadian rhythm, with energy naturally dipping between 1 PM and 3 PM.
• Heavy, carb-rich meals cause blood sugar spikes and drops, leading to fatigue and sleepiness.
• Digestion diverts blood flow to the gut, temporarily reducing energy to the brain.
• Increased insulin after meals boosts tryptophan, leading to serotonin and melatonin production, promoting sleep.
• Control sleepiness by eating light, balanced meals with protein and fiber, taking short walks, staying hydrated, and ensuring adequate sleep.
