Here are some key takeaways from the University of Notre Dame's resident sleep expert:
Your brain doesn’t take the night off -- In fact, it's incredibly busy. Many regions of the brain -- especially those involved in learning, processing information, and emotion -- are more active during sleep than when you’re awake.
Daytime naps aren't just for kindergarten -- A 90 minute nap could be as beneficial as a full night of sleep, and a 20 minute nap isn't far behind in benefits. The best time for a nap? In the afternoon, after lunch.
You can't just "make up" lost sleep -- Eventually, you lose so much sleep, you're not able to recover that sleep debt.
Even 20 extra minutes makes a big difference -- If you're not getting enough sleep, tack on 20 extra minutes on a regular basis. That alone will help you begin to reap the brain-building benefits of sleep.
