There are good reasons to drink coffee before napping. Coffee's caffeine starts functioning after 20 minutes.
If you drink a cup of coffee and then lie down for a quick nap, the caffeine will begin to take effect just as you should be waking up.
The Sleep Foundation suggests that a brief nap last no more than 20 minutes since any longer and you risk feeling drowsy upon waking up.
When taken at the right time, coffee and naps can help you feel rejuvenated and ready to take on the day.
Coffee before a nap has some downsides too. If you don't time it right, you may become too energized to take a nap.
In addition to headaches, dizziness, and insomnia, too much caffeine might have adverse health effects.
Finally, it may be worth a go, but make sure to time it right and restrict your caffeine intake each day.
