Have you ever felt like taking a quick nap between work or study sessions? In fact, there is an optimal length of time for a nap. That is 15 to 30 minutes .

Why 15 to 30 minutes is good?

If you take a nap longer than 30 minutes, your body will begin to prepare for deep sleep, which can cause you to feel drowsy or heavy when you wake up.

On the other hand, a short nap of around 15 to 30 minutes will wake you up in a light sleep state, allowing you to return to your activities feeling refreshed. This moderate length is the key to improving your work efficiency and concentration.

• Don't let your body get too cold . Maintaining a moderate temperature will make it easier to wake up after a nap.
• Make good use of caffeine <br>If you drink coffee or tea before taking a nap, the caffeine will kick in just as you wake up, and you may wake up feeling refreshed.
