字幕可核对事实展开收起

字幕依据：It’s only lunchtime and you still have so much to do. Our sleep, both at night and in naps, is made up of approximately 90 minute sleep cycles with four stages each. A nap can last anywhere from five minutes to three hours, so it can include full sleep cycles or just a few stages. BN9yqF6Um98@0:07
字幕依据：This phase lasts about 20 to 30 minutes and is where your deepest sleep occurs. Then, you enter REM sleep, which lasts about 10 to 20 minutes in a nap. In REM, the brain becomes more active, more like your brain activity while awake. BN9yqF6Um98@1:15
字幕依据：Stage 3 is the most difficult stage to wake up from. So while a 30 to 60 minute nap can have cognitive benefits, those benefits often don’t kick in until about 15 minutes after waking up. 60 to 90 minute naps enter the REM stage. BN9yqF6Um98@2:30
字幕依据：Our need for deep Stage 3 sleep progressively increases throughout the day. So if you nap later, you may rob yourself of the sleep pressure needed to go to sleep at night. Longer periods of REM occur during morning hours, so morning naps are dominated by REM, midday naps have about equal parts of REM and deep sleep, and evening naps contain more deep sleep. BN9yqF6Um98@3:36
字幕依据：You've been up for about 8 hours, maybe more. You're starting to feel that lull as far as energy levels and you're thinking about a nap. It might be the exact pick me up you need, but how good are naps for you anyway? Doctor Cheryl Ziegler is here with us to talk about Naps. bJSxsqsCOH8@0:00
字幕依据：So if you wake up at 6:00 AM at about 2:00 to 3:00 in the afternoon, most adults start to feel that low, and that's when they grab the coffee. Right, so this is the alternative to grabbing the coffee. I've always been a big fan of the siesta some cultures. bJSxsqsCOH8@1:05
字幕依据：So a lot of also physical health data to say that it helps you live longer because overall it's really restorative when we live in such a high stress world. You know, I've always said, you know, you're in preschool and kindergarten and they tell you it's nap time and you're like no and then the rest of your life you crave it. bJSxsqsCOH8@2:11
字幕依据：Plenty of people are doing a great job exercising and dieting. You know, it's it's in the middle of their day. When you say you hit about 8 hours, that may not be doable for them. I want to tell you that I started when I was a mom. bJSxsqsCOH8@3:19
