Doctor Explains 15 Things That Happen To Your Body When You Take A Nap Every Day

For the most part, our average day is divided into two periods: wake and sleep. As the quoted statistic shows, 85 percent of all mammals – humans belong to this group – sleep for short periods throughout the day. In other words, we’re the odd ones out.

Besides isolating ourselves from most of our mammal friends, humans are perhaps the only species that doesn’t get enough sleep: about 40 percent of us do not get the recommended 7 hours per night. While napping – brief periods of rest not exceeding 90 minutes – cannot correct our sleep deficit; it can certainly improve our efficiency, health and well-being, and mood.

Healthy Napping

You may not know that naps are actually divided into three categories: emergency, habitual, and prepatory.

Habitual napping, that is, the practice of taking a nap at the same time each day, is the healthiest option. Naps that must be planned before sleepiness sets in (prepatory) are good for someone who knows they will go an extended period without sleep. Emergency napping – or suddenly falling asleep from exhaustion – is in no way healthy, as we’ve seen from work-related disasters.

The National Sleep Foundation (NSF) recommends taking 20-30 minute naps for a boost in alertness and performance. Any period of sleep lasting between 30 to 60 minutes may cause sleep inertia or a groggy feeling post-wakeup. In any case, a nap lasting between 20 to 60 minutes is mostly beneficial.

The Benefits Of Napping
1. You’Re Happier
Science suggests that people who take a mid-day nap of 30 minutes or less enjoy an afternoon “happy boost” more often than those who nap longer than 30 minutes, or who don’t nap at all.

2. You Can Beat The Slump
Our circadian cycle feels a “slump” around 3 p.m. – an evolutionary hiccup. However, according to Harvard University, napping is an efficient way to bust this slump. (Yes, it’s even better than caffeine!)

3. You Make Fewer Mistakes
According to the NSF, napping improves work performance, reduces mistakes, and avoids accidents.

4. You’Ll Perform Better
In a study conducted by NASA, pilots and astronauts who took a 40-minute nap experienced a sizable improvement in their performance and alertness: 34 percent and 100 percent, respectively.

5. You Get A Memory Boost
College students, pay attention. Researchers at Saarland University in Germany found that taking a nap for 45-60 minutes improved their memory 500 percent. Get to your rack!
