Polyphasic Sleep Experiment

What is Polyphasic Sleep Experiment?

Instead of one 8-hour sleep block, use multiple shorter sleep periods: the most practical version is biphasic sleep (6 hours at night + 20 min afternoon nap). Some cultures have practiced this for centuries. Not for everyone, but worth testing.

Is there evidence for it?

How do you do Polyphasic Sleep Experiment?

1. 1.Start with biphasic: 6-6.5 hours of core sleep at night + one 20-minute nap between 1-3 PM
2. 2.The nap must be 20 minutes or less — set an alarm. Going longer drops you into deep sleep and you'll wake groggy
3. 3.Adaptation takes 1-2 weeks. The first few days you'll feel tired. By week 2, the nap becomes a superpower — you get a second morning
4. 4.Track: energy levels, mood, cognitive performance, and nighttime sleep quality. If your night sleep suffers after 2 weeks, this isn't for you
5. 5.Important: this only works if your 6-hour core sleep is CONSISTENT (same time every night) and HIGH QUALITY (dark room, cool, no alcohol). Fragmented bad sleep + naps ≠ polyphasic sleep

How long does it take?
