体验达芬奇睡眠法

引：每工作4小时睡15分钟。这样， 一昼夜花在睡眠上的时间累计只有1．5小时

Polyphasic sleep is a term used to describe several alternative sleep patterns intended to reduce sleep time to 2–6 hours daily in order to achieve a better quality of sleep. This is achieved by spreading out sleep into short naps of around 15–30 minutes throughout the day, and in some variants, a core sleep period of a few hours at night.

Polyphasic sleep involves taking multiple short sleep periods throughout the day instead of getting all your sleep in one long chunk. A popular form of polyphasic sleep, the Uberman sleep schedule, suggests that you sleep 20-30 minutes six times per day, with equally spaced naps every 4 hours around the clock. This means you’re only sleeping 2-3 hours per day. I’d previously heard of polyphasic sleep, but until now I hadn’t come across practical schedules that people seem to be reporting interesting results with.

Under this sleep schedule, your sleep times might be at 2am, 6am, 10am, 2pm, 6pm, and 10pm. And each time you’d sleep for only 20-30 minutes. This is nice because the times are the same whether AM or PM, and they’re consistent from day to day as well, so you can still maintain a regular daily schedule, albeit a very different one.

How can this sleep schedule work? Supposedly it takes about a week to adjust to it. A normal sleep cycle is 90 minutes, and REM sleep occurs late in this cycle. REM is the most important phase of sleep, the one in which you experience dreams, and when deprived of REM for too long, you suffer serious negative consequences. Polyphasic sleep conditions your body to learn to enter REM sleep immediately when you begin sleeping instead of much later in the sleep cycle. So during the first week you experience sleep deprivation as your body learns to adapt to shorter sleep cycles, but after the adaptation you’ll feel fine, maybe even better than before.

It requires some discipline to successfully transition to this cycle, as well as a flexible schedule that allows it. While you’ll be sleeping a lot less, apparently it’s very important to sleep at the required times and not miss naps.

达芬奇睡眠是在一天内安排多个短时间睡眠，而不是一天只睡长长的一个晚上，即多阶段睡眠。最流行的一种多阶段睡眠时间表Uberman睡眠时 间表中，建议你一天睡6次，一次睡20~30分钟，即每隔4个小时就小睡一次。
