Snooze and conquer. National Napping Day

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.

In Uganda's Queen Elizabeth National Park, some lions take napping to new heights—quite literally. The tree-climbing lions of the Ishasha Sector have a habit of sprawling across the branches of giant fig trees, as seen in today's image. Experts believe they climb to escape ground-level heat or pesky insects, but these naps make for an unforgettable sight. This vast park spans volcanic craters, open plains and dense forests. A safari here promises encounters with Uganda's incredible wildlife.
