“…As also observed in a study by Vagiakis et al (31), REM sleep latency was also longer in women than in men. Taken altogether, differences between genders could be due to the effects of cyclic levels of female reproductive hormones on sleep (20,32). Conceivably, this suggests that women are either more susceptible to clinical symptoms deriving from inadequate sleep or are more likely to report symptoms in general (33).…”

Our objective was to examine the effect of gender on the sleep pattern of patients referred to a sleep laboratory. The data (questionnaires and polysomnographic recordings) were collected from a total of 2365 patients (1550 men and 815 women). The polysomnography permits an objective assessment of the sleep pattern. We included only polysomnography exams obtained with no more than one recording system in order to permit normalization of the data. Men had a significantly higher body mass index than women (28.5 ± 4.8 vs 27.7 ± 6.35 kg/m 2 ) and had a significantly higher score on the Epworth Sleepiness Scale (10.8 ± 5.3 vs 9.5 ± 6.0), suggesting daytime sleepiness. Women had a significantly higher sleep latency than men, as well as a higher rapid eye movement (REM) latency. Men spent more time in stages 1 (4.6 ± 4.1 vs 3.9 ± 3.8) and 2 (57.0 ± 10.5 vs 55.2 ± 10.1) of non-REM sleep than women, whereas women spent significantly more time in deep sleep stages (3 and 4) than men (22.6 ± 9.0 vs 19.9 ± 9.0). The apnea/hypopnea and arousal indexes were significantly higher and more frequent in men than in women (31.0 ± 31.5 vs 17.3 ± 19.7). Also, periodic leg movement index did not differ significantly between genders, but rather differed among age groups. We did not find significant differences between genders in the percentage of REM sleep and sleep efficiency. The results of the current study suggest that there are specific gender differences in sleep pattern.

“…6 These sex-based differences also exist in middle-aged and elderly populations. 7 Chronotype or morningness-eveningness (i.e., the tendency to be an early ''lark'' or a late ''owl'') also appears to be influenced: Women consistently show a greater skew toward morningness than men. [8][9][10][11] Women also have been reported to have an earlier entrained circadian phase 12 and a shorter average intrinsic circadian period than men, 13 though not consistently.…”

This article is part of a larger body of work entitled, ''The Impact of Sex and Gender on Adaptation to Space.'' It was developed in response to a recommendation from the 2011 National Academy of Sciences Decadal Survey, ''Recapturing a Future for Space Exploration: Life and Physical Sciences for a New Era,'' which emphasized the need to fully understand sex and gender differences. In this article, our workgroup-consisting of expert scientists and clinicians from academia and the private sector-investigated and summarized the current body of published and unpublished human research performed to date related to sex-and gender-based differences in behavioral adaptations to human spaceflight. This review identifies sex-related differences in: (1) sleep, circadian rhythms, and neurobehavioral measures; (2) personality, group interactions, and work performance and satisfaction; and (3) stress and clinical disorders. Differences in these areas substantially impact the risks and optimal medical care required by space-faring women. To ensure the health and safety of male and female astronauts during long-duration space missions, it is imperative to understand the influences that sex and gender have on behavioral health changes occurring during spaceflight.

“…39,40 Even the sleep complaints commonly associated with menopause may be largely subjective, with the largest study using polysomnography, the gold-standard objective measure of sleep, finding that objective sleep quality is better during and after menopause than before it. 41 In younger subjects, fewer gender differences have been demonstrated, but females have been reported to experience shortened sleep latencies, 42 fewer awakenings, 42 less SWS in the second half of the night 43 and overall higher sleep quality compared with males. As -*Hazard ratios were adjusted for age, race, education, occupation, marital status, exercise level, smoking at baseline, years of smoking, church-going, fat and fibre intake, insomnia frequency, subjective 'sickness', 'upset', body mass index (BMI), leg pain, history of heart disease, hypertension, cancer, diabetes, stroke, bronchitis, emphysema, kidney disease, sleeping pills, antihypertensives, diuretics, Tylenol and Tagamet.…”

SUMMARY1. The aim of the present review is to outline: (i) the association between sleep and metabolism; (ii) how sleep duration influences the development of disease; and (iii) how sex differences, ageing and obesity may potentially influence the relationship between sleep, metabolic control and subsequent disease.2. Sleep is associated with a number of endocrine changes, including a change in insulin action in healthy young individuals. Sleep duration shows a prospective U-shaped relationship with all-cause mortality, cardiovascular disease and Type 2 diabetes.3. Chronic sleep restriction is becoming more common. Experimental sleep restriction impedes daytime glucose control and increases appetite.4. The sex hormones oestrogen and testosterone influence sleep duration and quality and may account for sex differences in the prevalence of sleep-related disorders.5. Ageing is associated with a decreased sleep duration, decreased muscle mass and impaired insulin action.6. Obesity impairs insulin action and is associated with the incidence and severity of obstructive sleep apnoea.7. Sleep plays an integral role in metabolic control. Consequently, insufficient sleep may represent a modifiable risk factor for the development of Type 2 diabetes. The challenge ahead is to identify how sex differences, ageing and obesity could potentially influence the relationship between sleep and metabolism.
