“…While sleep duration and quality have been reported to decline with age across adulthood (Floyd et al, 2007), robust associations have not consistently been observed (Reyner et al, 1995) and may depend on sampling factors such as the health status of study participants (Bliwise, 1993). Indeed, recent studies controlling for health factors have observed increases in sleep quality across adulthood into old age (Grander et al, 2012; Luca et al, in press).…”

Objective Despite evidence for detrimental effects of alcohol on sleep quality in laboratory studies, alcohol is commonly used as a self-prescribed sleep aid. This study examined the within-person associations of alcohol use with sleep duration and quality in everyday life to gain insight into the ecological validity of laboratory findings on the association between sleep and alcohol. Method A sample of 150 adults (age 19–89 years) were followed for 60+ days as part of an intensive experience sampling study wherein participants provided daily reports of their alcohol use, sleep duration, and sleep quality. Within-person and between-person associations of daily sleep duration and quality with alcohol use were examined using multilevel models. Results A significant, negative within-person association was observed between sleep quality and alcohol use. Sleep quality was lower on nights following alcohol use. Sleep duration did not vary as a function of within-person variation in alcohol use. Conclusions In line with laboratory assessments, alcohol use was associated with low sleep quality but was not associated with sleep duration, suggesting that laboratory findings generalize to everyday life. This examination of individuals’ daily lives suggests that alcohol does not systematically improve sleep quality or duration in real life.

“…However, as we age, there tends to be a shift in REM sleep to earlier in the night, resulting in a slightly decreased latency to REM sleep [ 7,9 ] . Also, a decrease of approximately 0.6% per decade in percentage of REM sleep [ 7,8 ] has been reported [ 10 ] , but this trend toward decreased REM percentage has not been found in all studies [ 9 ] .…”

The purpose of this chapter is to discuss changes in sleep quality and architecture that occur as one ages. Normal age related changes in sleep architecture will be discussed fi rst, followed by sleep and circadian rhythm disorders that increase in prevalence as we age. Finally, a short section at the end of this chapter discusses neurological disorders more frequently seen in older adults, and their impact on sleep.There is a general perception that degradation of sleep quality is a normal part of aging. In fact, practitioners who see geriatric patients on a regular basis often hear complaints of sleep difficulties in their patients. As we age, a number of age-related health problems are associated with difficulty sleeping. It is often difficult to differentiate sleep problems secondary to underlying health problems or medication effects from primary sleep disorders. This chapter will review the changes that occur in sleep quality as one ages and will address sleep disorders often seen in the older adults. The data discussed within this chapter is almost exclusively based on defining age chronologically. Some have argued that subjective or physiological age and time from death are more accurate ways of defining age; however, chronological age is the most consistent definition for aging. Therefore, it is the one used within this chapter. Changes in Sleep Architecture as We AgeA number of studies have been conducted to look at changes in sleep architecture over the life span. One of the most consistent age-related changes in sleep architecture is a decline in delta or slow-wave sleep (SWS). SWS is de fi ned electrographically by low-frequency (0.5-2 Hz), high-amplitude (>75 m V) waveforms [ 1 ] and is primarily con fi ned to the fi rst half of the sleep

“…In phylogeny, this function of REM sleep is advantageous to explain the various exceptions of REM sleep, especially the absence of REM sleep in dolphins (Cai, 2015b;Lyamin et al, 2007;Madan & Jha, 2012;Sekiguchi et al, 2006;Siegel, 2008) and short duration of REM sleep in birds (Ayala-Guerrero et al, 1988Cai, 2015b) in contrary to that in humans (Cai, 2015b;Floyd et al, 2007) and rodents (Cai, 2015b;Rechtschaffen et al, 1989), the absence of penile erections in REM sleep in armadillo (Affanni et al, 2001;Cai, 2015b), as well as the higher voltage in EEG during REM sleep in platypus (Cai, 2015b;Siegel et al, 1998;1999) and ostrich (Cai, 2015b;Lesku et al, 2011). In physiology, this function of REM sleep is advantageous to explain the association of REM sleep with the atonic episodes in SWS (Cai, 2015b;Tinguely et al, 2006;Werth et al, 2002), the absence of drastic menopausal change in duration of REM sleep (Cai, 2015b;Kalleinen et al, 2008;Orff et al, 2012;Shaver et al, 1988), and the different effects of ambient temperature on duration of REM sleep in rodents (Amici et al, 1998;Cai, 2015b;Rosenthal & Vogel, 1993;1994;Roussel et al, 1984) and humans (Cai, 2015b;Haskell et al, 1981;Karacan et al, 1978).…”

“…In accordance, even though there is drastic decrease in sexual drive in menopause, there is little menopausal change in duration of REM sleep, disagreeing with the brain function of REM sleep for conflict of emotional memories against disinhibited drives in humans, while supporting the function of REM sleep as improvement of muscular efficiency relatively. As the REM sleep declines roughly with aging (Floyd et al, 2007), immobility is obviously neither the major function of REM sleep in humans.…”

With preliminary classification, there are five behavioral functions for rapid eye movement(REM) sleep after puberty, which are memory retention, drive dissipation, muscular efficiency, heat control and adaptive immobility. For these diversities, it is newly suggested in this mini-review to categorize the REM sleep into two types respectively as atonic and brain REM sleep. In concrete words, the atonic REM sleep was acquired early in platypus, ostrich, and reptiles, responsible for the adaptive immobility as rare exceptions to predation risk of sleep, for the important function recently proposed for improvement of muscular efficiency in most species, and for the heat control in some species, while the brain REM sleep were added later in evolution, responsible for conflict of emotional memories against disinhibited drives.In ecological aspects, this division of REM sleep is useful to pluralistically understand the diverse adaptive functions of REM sleep in various species. On inductive relation, the atonia is required for EEG activation from brain stem in REM sleep, consistent with the earlier origin of atonic sleep in evolution. On physiological paradox, the pathological high muscle tension in human depression results from the emotional stress from accumulated emotional memories processed in long REM sleep, therefore not contradictory with the atonic function of REM sleep. On stage interactions, these two types of REM sleep are different as coherent and counteractive with SWS respectively. In these respects, the REM sleep plays two types of qualitatively different functions in the atonic and brain REM sleep respectively.
