Naps Can Seriously Improve All-Day Learning Abilities

Taking a 90-minute nap the day of a test or presentation sounds like a ludicrous luxury. But a recent study on the brain’s ability to recall facts found that napping at noon could mean a lot more brain power at 6 p.m.

Presenting at this year’s meeting of the American Association of the Advancement of Science (AAAS), University of California Berkeley researchers revealed the results of testing “39 healthy young adults” on recalling facts they had learned that same day.

At noon, all the participants were subjected to a rigorous learning task intended to tax the hippocampus, a region of the brain that helps store fact-based memories. Both groups performed at comparable levels.

At 2 p.m., the nap group took a 90-minute siesta while the no-nap group stayed awake. Later that day, at 6 p.m., participants performed a new round of learning exercises. Those who remained awake throughout the day became worse at learning. In contrast, those who napped did markedly better and actually improved in their capacity to learn.

It’s not the first time, or the second, that we’ve seen naps and memory functions tied together. But each study has its participants trying out slightly different tasks, and this study suggests that if you’re trying to cram in facts you need to recall later, a same-day nap before your last-minute cram might be more helpful than powering through your day with nervous energy.

It also suggests that the brain uses a sleep state between light sleep and deep REM phases to pull a kind of soft reset on the brain’s memory recall powers, so a fear that you can’t let yourself sleep “too deeply” in a nap seems unfounded.

10 Simple Ways to Control Stress

  1. Control Your Anger
    Watch for the next instance in which you find yourself becoming annoyed or angry at something trivial or unimportant, then practice letting go – make a conscious choice not to become angry or upset. Do not allow yourself to waste thought and energy where it isn’t deserved. Effective anger management is a tried-and-true stress reducer.
  2. Breathe
    Breathe slowly and deeply. Before reacting to the next stressful occurrence, take three deep breaths and release them slowly. If you have a few minutes, try out breathing exercises such as meditation or guided imagery.

  3. Slow Down
    Whenever you feel overwhelmed by stress, practice speaking more slowly than usual. You’ll find that you think more clearly and react more reasonably to stressful situations. Stressed people tend to speak fast and breathlessly; by slowing down your speech you’ll also appear less anxious and more in control of any situation.

  4. Complete One Simple To Do
    Jump start an effective time management strategy. Choose one simple thing you have been putting off (e.g. returning a phone call, making a doctor’s appointment) and do it immediately. Just taking care of one nagging responsibility can be energizing and can improve your attitude.

  5. Get Some Fresh Air
    Get outdoors for a brief break. Our grandparents were right about the healing power of fresh air. Don’t be deterred by foul weather or a full schedule. Even five minutes on a balcony or terrace can be rejuvenating.

  6. Avoid Hunger and Dehydration
    Drink plenty of water and eat small, nutritious snacks. Hunger and dehydration, even before you’re aware of them, can provoke aggressiveness and exacerbate feelings of anxiety and stress.
  7. Do a Quick Posture Check
    Hold your head and shoulders upright and avoid stooping or slumping. Bad posture can lead to muscle tension, pain, and increased stress.
  8. Recharge at the Day’s End
    Plan something rewarding for the end of your stressful day, even if only a relaxing bath or half an hour with a good book. Put aside work, housekeeping or family concerns for a brief period before bedtime and allow yourself to fully relax. Don’t spend this time planning tomorrow’s schedule or doing chores you didn’t get around to during the day. Remember that you need time to recharge and energize yourself – you’ll be much better prepared to face another stressful day.
