“…Beneficial effects of naps have been reported, especially among younger adults. In young volunteers, at least one study 55 has shown the countereffect on immune function from 30-min midday nap in subjects with sleep deprivation the night before. In more recent studies also in young volunteers, 30-min naps after sleep restriction in a laboratory setting restored urinary norepinephrine levels, 56 and 45-to 60-min naps facilitated blood pressure recovery from mental stressors.…”

Study Objectives: Short sleep duration and poor sleep quality are associated with adverse cardiovascular outcomes. Potential pathophysiological mechanisms include sleep-associated alterations in the autonomic nervous system. The objective of this study was to examine the associations of shorter sleep duration and poorer sleep quality with markers of autonomic tone: heart rate (HR), high-frequency HR variability (HF-HRV) and salivary amylase. Methods: Cross-sectional analysis of data from actigraphy-based measures of sleep duration and efficiency and responses to a challenge protocol obtained from 527 adult participants in the Multi-Ethnic Study of Atherosclerosis. Results: Participants who slept fewer than 6 h per night (compared to those who slept 7 h or more per night) had higher baseline HR (fully adjusted model 0.05 log beats/min, 95% confidence interval [CI] 0.01, 0.09) and greater HR orthostatic reactivity (fully adjusted model 0.02 log beats/min, 95% CI 0.002, 0.023). Participants who slept 6 to less than 7 h/night (compared to those who slept 7 h or more per night) had lower baseline HF-HRV (fully adjusted model −0.31 log msec 2 , 95% CI −0.60, −0.14). Participants with low sleep efficiency had lower baseline HF-HRV than those with higher sleep efficiency (fully adjusted model −0.59 log msec 2 , 95% CI −1.03, −0.15). Participants with low sleep efficiency had higher baseline levels of amylase than those with higher sleep efficiency (fully adjusted model 0.45 log U/mL, 95% CI 0.04, 0.86). Conclusions: Short sleep duration, low sleep efficiency, and insomnia combined with short sleep duration were associated with markers of autonomic tone that indicate lower levels of cardiac parasympathetic (vagal) tone and/or higher levels of sympathetic tone.

“…An experimental study conducted with healthy subjects showed that a single night of sleep deprivation is sufficient to cause these increases that return to baseline only with ten hours of recovery sleep. Cancer patients experiencing chronic sleep loss may be more vulnerable to these immunological changes because of the obstacles in obtaining sufficient recovery sleep, thus mounting an exacerbated and sustained inflammatory response [7].…”

“…A followup of those women, 2 to 7 months after baseline, revealed that 20% of those who reported poor sleep quality had worsening of clinical symptoms and 8% died [11,7] The recognition that poor sleep quality may represent a prognostic factor in cancer patients should encourage nurses and other health professionals to give special attention to this important aspect of routine life [4,12] …”

Background: Sleep disturbances are a chronic and challenging problem in cancer patients, often associated with multiple factors such as depression, anxiety, fatigue and pain. Aim:The purpose of this integrative review is to evaluate the literature on sleep quality in women with breast cancer and the influence that poor sleep quality has on health. Results: Findings support the presence of poor sleep quality in many women with breast cancer, before, during and after treatment associated with health issues. Methods: Conclusions:Sleep disruptions are associated with breast cancer in woman, and affects their overall health. It is essential for nurses to identify sleep disorders and their impact on the health and quality of life of women with breast cancer. A deeper understanding of sleep quality in women with breast cancer can increase cancer nurses' skill in caring for their patients.

“…Given that poor sleep continuity and quality are important correlates of adverse pregnancy outcomes, 5 propose that a beneficial countermeasure to sleep disruption is daytime naps, which is in line with several other reports in non-pregnant cohorts. [9][10][11]41 Additional research is still needed to determine the effect of naps > 30 min on pregnant women.…”

Study Objectives: To assess whether daytime naps negatively impact nocturnal sleep. Design: Longitudinal, prospective cohort design. Participants: 161 pregnant women recruited and evaluated in early gestation (10-20 weeks). Measurements and Results: Daily sleep information was collected in three 2-week periods (10-12, 14-16, and 18-20 weeks gestation) with a daily sleep diary and an actigraph. The average number of naps, as well as the average length of each nap, were calculated from sleep diaries. Women were categorized fi rst as non nappers (0 naps/2-week period), moderate nappers (1-3 naps/2-week period), or frequent nappers (≥ 4 naps/2-week period). Then, based on the average nap length, they were categorized as short (< 90 min) or long (≥ 90 min) nappers. Nocturnal sleep parameters included SOL, WASO, SE, and TST. SAS procedure MIXED was used for modeling the main effects of nap group and time, and time by nap group interactions. Women who took naps had a decrease in diary-assessed nocturnal TST, but not actigraphy-assessed TST. This observation was group-and time-specifi c. There were no other group differences. Women who napped ≥ 90 min had poorer diary-assessed SE and lower diary-assessed TST than those who took shorter naps. Length of nap was not associated with any other sleep measures. Conclusions:The number of daytime naps have minimal impact on nocturnal sleep parameters; however, long nappers did exhibit modestly impaired sleep continuity and sleep quality. Overall, we propose that daytime naps provide a benefi cial countermeasure to the sleep disruption commonly reported by pregnant women. This may be clinically benefi cial given that sleep continuity and quality are important correlates of pregnancy outcomes. T he majority of expectant women experience progressively disturbed, fragmented, and shortened nocturnal sleep as a result of normal physiological adaptations to the progressing pregnancy.1-3 Emerging evidence indicates that insuffi cient quantity and poor sleep quality are associated with increased risk of mood dysregulation , 4,5 as well as adverse pregnancy outcomes, such as preterm birth and gestational diabete s. 6-8When suffi cient nighttime sleep is not possible or unattainable, certain strategies can be implemented to counteract the negative effects of disturbed nocturnal sleep. One promising approach is to include daytime naps as part of a healthy sleep hygiene progra m. 9-11There is limited information examining the effects of daytime naps on nocturnal sleep outcomes in non-pregnant populations. The majority of evidence stems from examination of daytime naps in elderly or middle-aged individuals or children. The bulk, however, consider daytime naps as a positive health behavior (a "countermeasure") in that they can effectively combat subjectively reported poor sleep quality and decrease subjective daytime sleepiness by augmenting shortened nocturnal sleep durat ion.11-14 However, there is also a small literature that suggests that naps can be detrimental to nocturnal sleep and ne...
