What Time of Day is Best to Limit Caffeine?

If you’re someone who loves a hot cup of tea or coffee, you’re probably no stranger to caffeine.

Caffeine is a stimulant, meaning that it activates your nervous system and makes you more alert and focused. Research shows that the maximum effects of caffeine are noticeable 30-60 minutes after its consumption.

This means that if you’re taking caffeine to improve your physical and mental performance, taking it no more than one hour before your workout or exam is key to your success.

However, caffeine has a half-life of 5-7 hours, meaning it is still in your system several hours after you drink your caffeinated beverage. Therefore, if you want to maximize your sleep, it’s best to consume caffeine before or up to 3 pm. After this point in the afternoon, limit your caffeine intake and switch to non-caffeinated alternatives.
