Caffeine and Sleep

Caffeine has a half-life of five to six hours, meaning it can linger in your system long after consumption, affecting your sleep quality. Even if you feel fine falling asleep after a late espresso, you may be sacrificing deep sleep, leaving you feeling unrefreshed in the morning. Limiting caffeine intake to before midday and keeping it to a maximum of three cups can help maintain better sleep health. For evening enjoyment, opting for decaf can be a wise choice.
