Daytime sleep can sharpen alertness

Dividing your day into work and rest periods can make you much more alert. A NASA study found a 100% increase in alertness in people who took a 40-minute nap. The research also showed that even a 20-minute nap can improve readiness. The effects of a nap can be compared to consuming 200 mg of caffeine.

Napping can dramatically boost creativity

Take artists like Leonardo da Vinci, who often napped several times a day while keeping nighttime sleep to a minimum. This lifestyle is believed to have greatly enhanced their creative potential. It may be due to the heightened senses that come with being well-rested.

Good rest strengthens memory

Working memory is essential in situations that require high concentration. It functions much better when you’re well-rested. A nap can even help preserve memories for the long term.

Naps sharpen the senses

A short nap can help preserve your sense of smell, taste, sight, and hearing. Allowing your body to rest briefly during the day can enhance sensory perception almost as much as a full night’s sleep. You may notice music sounding richer or food tasting better.

Napping supports physical health

People who are sleep-deprived tend to have higher levels of cortisol—the stress hormone. Excess cortisol can damage the immune system and disrupt the balance of other vital hormones. Napping helps your body release growth hormones, which neutralize cortisol and lower physiological stress levels.
