4. Skip the snooze. Disrupting sleep an hour or so before actually getting out of bed may disturb our REM cycle, which helps stimulate brain regions linked to cognition. Don’t want to mess with that (or bug a roommate with multiple alarms!). Set one alarm for when it’s time to rise—and maybe another a few minutes later in case you snooze through.

不要貪睡。 還沒(méi)完全睡醒準(zhǔn)備起床卻被打擾，這樣可能會(huì)擾亂人體的REM（快速眼球運(yùn)動(dòng)）周期，而REM則會(huì)刺激大腦的認(rèn)知區(qū)域。所以不要那樣，也不要設(shè)太多鬧鐘攪得室友睡不好覺(jué)！只在該起床的時(shí)間點(diǎn)設(shè)一個(gè)鬧鐘就行了，要是你特容易睡過(guò)頭，那就再調(diào)一個(gè)幾分鐘之后的吧。
