I have extensive experience with it. I would disagree that there’s nothing irresponsible. I don’t recommend anyone try skipping a night just to see. Blood pressure, heart rate, and glucose levels can easily go to shit and exacerbate underlying any conditions. FWIW it would take me 1-2 weeks after shifting to a polyphasic before seeing any benefits (which makes sense, respective to jet lag). I can easily skip a single night (without stimulants, etc) and run off adrenaline the next day, but the day after sleeping again I’m useless state of sleep-lag-wtf.

Mediocre analogy: something like polyphasic sleep with extremely disciplined sleep-hygiene is like using a stack of high-interest credit cards for the rewards/benefits, but if you make a mistake then there’s a high cost and it’s not really tenable forever. Skipping a night of sleep outright is basically a pay-day loan.
