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. The statistics show that 85 percent of all the mammals (humans belong to this group) sleep for short periods throughout the day.

Humans are perhaps the only species that doesn’t get enough sleep. In fact, about 40 percent of us do not get the recommended 7-8 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.



You may not know, but naps are divided into 3 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 most beneficial.

The benefits of napping

1. You are 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, napping is an efficient way to bust this slump according to Harvard University.

3. You make fewer mistakes

According to the National Sleep Foundation, 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 (34 percent improvement) and alertness (100 percent improvement).

5. You get a memory boost

Researchers at Saarland University in Germany found that College students who were taking a nap for 45-60 minutes improved their memory 500 percent.

6. You’re more creative

Napping is not a mindless activity. In fact, research shows that the right side of the brain – where creativity and “whole picture thinking” takes place – is actively communicating with itself.

7. Your heart is healthier

Per a joint research study performed by the Harvard School of Public Health and the University of Athens Medical School (Greece), people who nap for 30 minutes or more, at least three times per week, had a 37 percent lower risk of dying from heart disease.

8. You’ll crave less junk food

According to a study by UC Berkeley, a lack of sleep impairs the brain’s prefrontal cortex, which is responsible for decision making and withstanding impulse. Clearly, any prefrontal cortex impairment is not good for resisting temptations – including junk food.

9. You feel fuller

When asleep, the body produces less of the “hunger hormone,” ghrelin. Researchers suggest that regular napping can increase satiety, or feelings of fullness.

10. You’ll bicker less

People that have poor sleeping patterns tend to be more sensitive and in fact, argue more compared to those that are getting their full amount of nighttime sleep and day naps.

11. You’ll decrease a risk of injury

According to the Centers for Disease Control and Prevention (CDC) and the National Highway Traffic Safety Administration (NHTSA), people are more likely to suffer a catastrophic industrial, motor vehicle, or medical incident if sleep-deprived. Just a 30-minute nap can quite possibly save your life.

12. You are more productive

Cornell University psychologist James Mass created the term – “power nap” which according to him that’s a practice that’s related to embracing and business productiveness. Why? Because the results have shown that naps result in enhanced productivity and performance.

13. You defend against burnout

According to the National Institutes of Health (NIH), napping helps counteract information overload and mental burnout. NIH also discovered a direct link between napping and enhanced cognitive performance.

14. You are helping your workplace

Nike and Deloitte Consulting reward employees for adding a mid-day nap to their to-do lists. Nike, Deloitte, and others recognize that today’s employees while working more, are getting less sleep. “Powering through” work by forgoing rest and working longer hours “isn’t good for the individual or the organization,” says UNC behavior professor Michael Christian.

15. You have better judgment

Your frontal lobe is in charge of all things related to decision-making. Lack of sleep negatively affects impulse control, which may lead to worse decisions than if one were fully rested. A 30-minute to 60-minute nap can hand us back the reins.
