Take a nap

15 – 30 minutes of napping promotes not only physical well-being, but also has psychology benefits. Recent studies have shown that napping has a positive psychological effect and may improve alertness, mood and performance.
- Do not fall into the deep sleep; 15 to 30 minutes of napping is ideal
- The napping environment should be restful with quiet, warm, and dark
- Nap time shouldn’t be too late or too early
