No Caffeine After 2 P.M.

One of the most naturally available sources of caffeine in the diet is coffee. Coffee is quite popular because it contains caffeine, a stimulant. It energizes you and keeps you awake while you're feeling sleepy.

However, consuming coffee after a certain time of day can keep you up at night. Numerous health issues have been linked to insufficient sleep. Caffeine has a quarter-life of 10 to 12 hours, meaning that if you have coffee to get through an early afternoon meeting, you could still have caffeine coursing through your system at midnight. It's crucial to avoid drinking coffee in the afternoon because of this. If you must, go for decaf or choose a cup of tea, which has a lot less caffeine than coffee. A good thumb rule is to avoid coffee between 2:00 and 3:30 p.m. Even tea, or a coke – best avoid them all.
