Episode notes
Strategic Coffee Consumption
- Drink coffee strategically for health benefits, but be mindful of timing and dosage.
- Limit caffeine intake 10-12 hours before bed due to its quarter-life of 10-12 hours.
Caffeine's Trifecta of Sleep Disruption
- Caffeine affects sleep in three ways: hindering falling asleep, increasing nighttime awakenings, and reducing deep sleep.
- Even if you fall asleep easily after caffeine, it can still negatively impact deep sleep quality.
Genetics of Caffeine Sensitivity
- Genetic variations influence caffeine sensitivity through the CYP1A2 gene, affecting its clearance rate.
- There aren't yet known ways to enhance this gene's activity, and relying on downers to counteract caffeine creates a dependency cycle.
