How Caffeine Blocks Sleep Pressure
- Caffeine works primarily by blocking adenosine receptors, preventing sleep pressure from being felt.
- It does not stop adenosine buildup, so sleep pressure returns when caffeine clears.
Caffeine Boosts Dopamine And Peaks Slowly
- Caffeine increases available dopamine by slowing dopamine reabsorption, adding to its stimulant effects.
- Peak effects arrive 1–2 hours after ingestion and onset can begin within 10 minutes.
Plan Around Caffeine's Half-Life
- Remember caffeine's half-life is roughly 3–7 hours and varies by individual factors like sex and medication.
- Plan intake with that half-life in mind because multiple half-life cycles are needed to clear caffeine.
