Episode notes
Thanksgiving Sleepiness
- The tryptophan in turkey doesn't make you sleepy.
- Overeating carbs, alcohol, and even stressful conversations are more likely culprits.
Tryptophan's Role
- Tryptophan is an essential amino acid found in various foods, not just turkey.
- It's crucial for serotonin and melatonin production, but large amounts are needed for a direct sleep effect.
Post-Meal Sleepiness
- Post-Thanksgiving dinner sleepiness is likely due to carb-heavy meals, not just tryptophan.
- This postprandial effect diverts blood flow from the brain and muscles to the gut.
