Is it true that if you want to get the most out of your caffeine intake, you should avoid caffeine for the first 90-120 minutes after waking? Why? This question is based on the Huberman Lab Podcast episode 'Optimize & Control Your Brain Chemistry to Improve Health & Performance | Huberman Lab Podcast #80' and the clip 'Optimizing Morning Routine.' Caffeine increases alertness by blocking adenosine receptors, so your brain is temporarily paused from receiving adenosine’s 'sleepy' signals. When you first wake up, your adenosine levels are already at their lowest, so you won’t feel the full benefits of the caffeine you’re drinking.
