“…If our wearable sleep staging results are validated, it would suggest that snoozing could share common mechanisms with “self-awakening” (intending to wake at a particular time before going to bed). Self-awakening has been shown to change arousal hormones and increase HR 1 h prior to the intended waking time [ 27 ], and to reduce sleep inertia upon waking. Thus, it may be that the anticipation of alarm(s) may change sleep staging in anticipation of waking.…”

“…From the Garmin vivoSmart 3, two sets of sleep staging scores per day were generated: percentage of time awake, light sleep (N1 + N2), deep sleep (N3), and stage R for the entire night, and the same for the last hour. The last hour (60 min prior to wearable detected wake time) was chosen due to findings of differential sleep staging and physiology for restricted sleepers practicing self-awakening [ 27 ]. In addition, HR was calculated across the entire night and last hour.…”

“…experimenter, alarm) [ 26 ]. Of these factors, only self-awakenings have been associated with increased hypothalamic pituitary adrenal axis (HPA) axis activity 60 min before self-awakening (for review, see [ 27 ]). Thus, waking naturally after sufficient sleep tends occur from light sleep, especially stage R sleep, is supported by a CAR, and generates low sleep inertia.…”

Study Objectives Snoozing was defined as using multiple alarms to accomplish waking, and considered as a method of sleep inertia reduction that utilizes the stress system. Surveys measured snoozing behavior including who, when, how, and why snoozing occurs. In addition, the physiological effects of snoozing on sleep were examined via wearable sleep staging and heart rate activity, both over a long time scale, and on the days that it occurs. We aimed to establish snoozing as a construct in need of additional study. Methods A novel survey examined snoozing prevalence, how snoozing was accomplished, and explored possible contributors and motivators of snoozing behavior in 450 participants. Trait- and day-level surveys were combined with wearable data to determine if snoozers sleep differently than non-snoozers, and how snoozers and non-snoozers differ in other areas, such as personality. Results 57% of participants snoozed. Being female, younger, having fewer steps, having lower conscientiousness, having more disturbed sleep, and being a more evening chronotype increased the likelihood of being a snoozer. Snoozers had elevated resting heart rate and showed lighter sleep before waking. Snoozers did not sleep less than non-snoozers nor did they feel more sleepiness or nap more often. Conclusions Snoozing is a common behavior associated with changes in sleep physiology before waking, both in a trait- and state-dependent manner, and is influenced by demographic and behavioral traits. Additional research is needed, especially in detailing the physiology of snoozing, its impact on health, and its interactions with observational studies of sleep.

“…Although extended wakefulness without sleep can increase performance lapses, and sleep can decrease these effects, the period immediately after awakening from sleep (for up to 2 hr, depending on the severity of prior sleep deprivation) can involve performance degraded by sleep inertia (Dinges, 1990;Jewett et al, 1999). Sleep inertia is reduced by self-awakening at a predetermined time without an external stimulus (Hayashi, Matsuura, & Ikeda, 2010). Its more severe cognitive deficits appear to be blocked by caffeine ingestion (Hayashi, Masuda, & Hori, 2003;Van Dongen et al, 2001).…”

Fatigue is the word used by the public and throughout government, industry, and labor to indicate the effects of working too long, following too little rest, and being unable to sustain a certain level of performance on a task (Dinges, 1995). These issues overlap extensively with those that relate to sleepiness and its performance effects, and consequently, sleepiness and fatigue are used interchangeably in this chapter.

SUMMARYThe ability to awaken at a predetermined time without an alarm is known as self-awakening. Self-awakening improves morning alertness by eliminating sleep inertia; however, the effects of self-awakening on daytime alertness and alertness that has deteriorated as a result of sleep loss are unknown. The aim of this study was to determine the effects of self-awakening on both morning and daytime alertness after partial sleep deprivation. Fifteen healthy males without the habit of self-awakening participated in a cross-over trial including forced awakening and selfawakening conditions. In each condition, participants' sleep was restricted to 5 h per night in their homes for 4 consecutive days. They completed a psychomotor vigilance task and subjective ratings of sleepiness immediately upon awakening each morning. On the fourth day, participants completed subjective ratings of sleepiness, a psychomotor vigilance task and sleep latency tests in the laboratory seven times at 1-h intervals during the day. The response speed on the psychomotor vigilance task, in the morning and during the day, was higher in the selfawakening than the forced awakening condition. Our results showed that self-awakening improved alertness (assessed by response speeds) by reducing sleep inertia and alleviated daytime sleepiness heightened by partial sleep deprivation.
