Translations:Dark period/42/en

It is recommended that you maintain a fasting period that covers the entirety of your dark period, as food is also an important zeitgeber, or circadian cue. Intermittent fasting has been anecdotally suggested to work well with polyphasic sleep. It is preferable to eat during the day rather than at night. A breakfast helps set the circadian day start. Water may be consumed, but any xenobiotic consumables will disrupt your circadian rhythm.
