Coffee Naps May Help Reduce Sleepiness and Boost Alertness
Coffee contains caffeine, which can help you feel more awake.
It works partly by blocking a brain chemical called adenosine that makes you sleepy.
A coffee nap means drinking coffee and then taking a short nap right away.
The caffeine usually takes about 20 to 30 minutes to start working in the brain.
This gives you time to rest before the caffeine boosts your alertness.
Set an alarm for about 20 minutes so you do not sleep too long.
Sleeping for more than 30 minutes may leave you feeling groggy.
Even quietly resting with your eyes closed may help refresh your mind.
Caffeine can increase alertness by blocking adenosine, a neurotransmitter linked to sleepiness.
A “coffee nap” involves drinking coffee immediately before taking a short nap.
Caffeine typically takes about 20 to 30 minutes to reach the brain and produce stimulant effects.
The recommended nap lasts about 20 minutes, and sleeping beyond 30 minutes may cause grogginess.
Even resting with closed eyes may help reduce fatigue, although medical advice should be sought when needed.
