Siestas

An interesting sleep fact from around the world is the concept of "siestas" in Spain and other Spanish-speaking countries. Traditionally, many people take a short nap after lunch, usually around 1-3 pm, to recharge and combat the midday heat. While this custom is becoming less common due to modern work schedules, it still holds cultural significance in many areas. The siesta is believed to improve alertness and productivity for the rest of the day, with studies showing that short naps (about 20-30 minutes) can enhance cognitive function and memory.

In contrast, in places like Japan, there's a tradition called "inemuri," where people nap in public spaces, such as on trains or at work. It’s seen as a sign of dedication and hard work, as people often stay up late and rise early. Rather than being stigmatized, napping during the day is considered socially acceptable and even admired.
