When should you drink coffee?

Andrew Huberman recommends delaying caffeine intake until 90 to 120 minutes after waking up to avoid the so-called afternoon crash. Delaying consumption helps maintain energy throughout the day and avoids disrupting nighttime sleep. Moreover, it is suggested to limit caffeine consumption after 2:00 PM to 3:00 PM to ensure it does not affect sleep quality. For those who exercise early in the morning, consuming caffeine right before exercising is acceptable, but a decrease in energy levels in the afternoon can be expected 1.
