When Adaptation Never Happens

Sometimes, polyphasic sleepers have trouble adapting to a schedule and may not be quite certain why.

There are a few common reasons for why this may occur:

1. Oversleeping is typically the main culprit for an endless adaptation. If you frequently oversleep, your body can never achieve the sleep repartitioning and alignment required to adapt (see also: OSS). Recovery is usually the best course of action in these situations.
2. Inconsistency is another common reason you may not be able to adapt. Discipline and consistency are extremely important for adapting, as skipping or flexing sleeps prevents your body from learning the schedule, which is vital for alignment. In addition, it's important to have a consistent dark-period every day so that your circadian rhythm is stable (an unstable circadian rhythm has many negative consequences, some of which can impact your ability to adapt).
3. Overwhelming sleep debt upon beginning a schedule can result in a failure to adapt, as you will be more prone to oversleeps due to your body's increased need for vitals. This is why recovery is important before beginning a schedule.
4. Excessive microsleeps may prevent you from adapting as well. If you microsleep more than a few times a day, your body may be preventing itself from reaching the sleep-debt threshold required for repartitioning to occur, since microsleeps can alleviate small amounts of sleep deprivation. Cumulatively, this can result in a perpetual stage-2 or stage-3.

When to stop

Adapting to polyphasic sleep schedules is very difficult, and it's common for beginners as well as more experienced polysleepers to fail. Unfortunately, determining when success is no longer attainable is not an easy task, especially with situations like Stage 3/4 loops where one repeatedly feels close to adapting, then falls back into the depths of sleep deprivation. In addition, the sunk-cost fallacy as well as the emotional weight of giving up on something that's been the focus of a lot of time, energy, and willpower can make abandoning an attempt extremely difficult. However, continuing an adaptation attempt will often not only lead to more time lost to an unattainable goal, but it will also unnecessarily increase the long-term health issues chronic sleep deprivation can cause (which are limited when attempts are shorter). For these reasons, it's incredibly important to learn how to determine when it's time to recover, retrospect, address failings or difficulties from the last attempt, and prepare to retry.

Guidelines to help determine when to recover:

1. Consistency: This is highly important when adapting, and a breakdown (be it skipping, flexing, undersleeping, or oversleeping) can be a sign of the end of an adaptation (see consistency). Sleep deprivation creates deficits in memory and judgement, which may lead to a vicious cycle where oversleeps are forgotten about or excused, only for more oversleeps to occur (see OSS). If you notice this, it is probably time to recover.
   • To avoid this in the first place, ensure your alarms are optimized, both for waking and reminding yourself when a sleep is approaching to avoid accidental flexing or worse, skipping. Prepare in advance for how difficult adaptations are, and be ready to commit fully and dedicate the willpower required to be consistent.
   • To avoid forgetting or excusing oversleeps, log your sleep - including oversleeps (for accountability, send in a logging channel!). Review your oversleeps and their frequency to assess any potential OSS. Log your oversleeps in a way that makes it easy to assess their frequency.
   • If you notice yourself brushing aside any oversleeps for reasons such as alarms not going off, making a mistake, or just not having enough willpower 'this one time', stop yourself! Forgetfulness and low willpower are symptoms of sleep deprivation and aren't always within your control. If they keep happening despite repeated commitments to do better, then you may need to accept that it's a pattern and consider recovering.
2. Total Sleep Time: The community's general guideline is: sleeping double your schedule's TST (total sleep time) at once is a full reset on your adaptation. If you achieve this or triple your TST in oversleeps in one week, it's almost certainly time to recover.

   To avoid oversleeping, make sure you're attempting a schedule that works for you (see adaptable), and optimize your alarm systems.

3. Advice: The community advisors and helpers may have a more objective perspective on your attempt's viability. This combined with the tendency of most to overestimate their ability to adapt (fueled by a lack of perspective due to sleep deprivation, sunk-cost fallacy, etc.) elevates the weight with which you should consider their recommendations.
4. Reading This: If you're reading this, you likely were either referred to it by someone who thinks you need to recover, or you sought it out. In either case, this may be your sign to consider stopping and recovering.
