One of the most widely used substances globally is caffeine, which has the ability to enhance alertness and wakefulness within approximately 15 minutes of ingestion.
However, while caffeine is a useful aid for combating morning fatigue, it can also have negative effects on sleep if consumed too late in the day.
This is because caffeine obstructs the adenosine receptors in the brain that promote drowsiness.
The half-life of caffeine is around three to six hours, and it can take up to 10 hours for caffeine to be completely eliminated from the body.
Even if consumed six hours before bedtime, caffeine can still interfere with sleep, and to promote a restful night's sleep, it may be advisable to avoid caffeine altogether in the afternoon.
Nevertheless, it is essential to bear in mind that each individual metabolizes caffeine uniquely, implying that the duration for which caffeine's effects persist may differ from person to person.
