Is It Okay to Drink Coffee in the Afternoon?

Caffeine has a half-life of approximately 5-6 hours — meaning half the caffeine from a 3pm cup is still in your system at 9pm. For most people, cutting off caffeine by 2pm is a reasonable guideline. If you're sensitive to caffeine, noon is safer. Matcha is often better for afternoon energy than coffee due to lower caffeine content and L-theanine's calming effect. If you need afternoon energy, consider half-serving instant coffee or switching to matcha for the second-half of your day.
