Feeling a bit tired? You're not alone—losing an hour to daylight saving time can leave anyone groggy. That's why Napping Day exists. Introduced in 1999 by William Anthony, a Boston University professor, and his wife, Camille, this unofficial holiday encourages everyone to take quality naps. Observed on the Monday after clocks spring forward, it's a reminder that rest is essential for well-being. Research backs it up—short naps boost mood, enhance concentration and sharpen memory. Napping is also linked to lower stress and better heart health. While power naps (20-30 minutes) are ideal for a quick recharge, even a few minutes of shut-eye can help.
