Is “Napping Is a Sign of Laziness” Really True? What Recent Insights Teach Us About Short Naps (Power Naps) and the Autonomic Nervous System

“Feeling sleepy during the day means I'm not focused enough,” “napping looks like slacking off” — many people probably still hold this kind of image. In June 2026, a press release related to an exhibition drew attention by introducing the growing use of short workplace naps, or “power naps.” Here's an easy-to-follow summary for readers in midlife and beyond.

The Idea of ‘Power Naps’ Introduced in the Release

• Japan's sleep duration is described as short even by international standards, with chronic sleep deprivation cited as a social issue. Diversifying lifestyles, including extended smartphone and computer use, are noted as making it harder for many people to get sufficient rest.
• Amid growing interest in work-style reform and health management, more companies are introducing “power nap” or “siesta” systems that make use of lunch breaks, the release notes. The idea presented is that short naps may help refresh mind and body and support work efficiency.
• Results from joint research with a university on napping using an item that gently covers the eyes are introduced. For detailed figures, readers should check the original source, but differences in relaxation were reportedly observed depending on how the rest was structured.

What We, in Midlife, Should Keep in Mind

This release conveys that napping isn't only for special people — resting skillfully in short bursts is spreading as an everyday health habit. The following commonly recommended ideas are said to help maintain your condition during the day.

• Rather than viewing napping as “slacking off,” try reconsidering a 15–20 minute nap as a daytime refresh habit
• Be mindful of timing and length, since a long nap later in the day can affect nighttime sleep
• Use an eye mask to block light, or choose a quiet environment, to help rest your eyes and ears

* The above are commonly recommended general health habits and do not guarantee improvement, treatment, or prevention of any specific condition.
