Background Sleep disturbances are common in patients with chronic obstructive pulmonary disease (COPD) with a considerable negative impact on their quality of life. However, factors associated with measures of sleep in daily life have not been investigated before nor has the association between sleep and the ability to engage in physical activity on a day-to-day basis been studied. Aims To provide insight into the relationship between actigraphic sleep measures and disease severity, exertional… 
Association between habitual physical activity (HPA) and sleep quality in patients with cystic fibrosis
TLDR
There is a strong correlation between times spent in vigorous to very vigorous intensities and better sleep quality and patients with poor sleep quality possibly benefit from an intensification of physical activity in the home environment.
Tossing and turning: association of sleep quantity–quality with physical activity in COPD
TLDR
It is shown, for the first time, that sleep quantity is a determinant factor of objectively assessed level of physical activity in subjects with COPD and that sleep quality is frequently poor and even worse in patients classified as physically inactive.
Impact of pulmonary rehabilitation in sleep in COPD patients measured by actigraphy
TLDR
Pulmonary rehabilitation improved subjective sleep quality in Veterans who had poor sleep quality at the beginning of the PR but did not improve objective sleep parameters by actigraphy, which highlights the complex interactions among COPD, sleep and exercise.
Pulmonary Rehabilitation does not Improve Objective Measures of Sleep Quality in People with Chronic Obstructive Pulmonary Disease
TLDR
Sleep quality, measured objectively using actigraphy, did not improve after an 8-week pulmonary rehabilitation program in individuals with COPD and whether on-going participation in regular exercise training beyond the duration of pulmonary rehabilitation may influence sleep quality is yet to be determined.
Sleep disturbance and next-day physical activity in COPD patients.
Characterization and determinants of sleep measured by self-report and wrist actigraphy in patients with interstitial lung disease
TLDR
Higher pain severity was an independent predictor of reduced sleep efficiency, increased sleep latency and greater number of sleep disturbances measured by the PSQI on adjusted analyses.
Impaired Sleep Quality in COPD Is Associated With Exacerbations: The CanCOLD Cohort Study.
Greater Sleep Fragmentation Is Associated With Less Physical Activity in Adults With Cystic Fibrosis
TLDR
A modest relationship between sleep parameters and physical activity and exercise capacity in adults with CF is demonstrated and future studies of interventions to promote physical activity participation in this group should consider the relationship betweenSleep and activity performance.
24-hour accelerometry in COPD: Exploring physical activity, sedentary behavior, sleep and clinical characteristics
TLDR
Distinct behavioral constructs comprising the 24-hour day were identified as “low- intensity movement,” “high-intensity movement” and “sleep” with each construct independently associated with different participant characteristics, to determine whether modifying these behaviors improves health outcomes in COPD.
Sleep and breathing disturbances in patients with chronic obstructive pulmonary disease traveling to altitude: a randomized trial
TLDR
During a stay at moderate altitude, lowlanders with moderate to severe COPD experience nocturnal hypoxemia that induces central sleep apneas, altered sleep structure, and insomnia.

Actigraphic assessment of sleep in chronic obstructive pulmonary disease
TLDR
Nocturnal sleep is markedly impaired in stable COPD patients studied by actigraphy in their home environment and this impairment is related to severity of dyspnea.
Changes in physical activity and sleep duration following hospitalisation with acute exacerbation of COPD
TLDR
3 months after hospitalisation COPD patients slept and exercised significantly more and rested less than when first discharged, while on recovery patients rested less, slept 55 mins longer (for 6hr 36min) and took more steps than in the acute state.
Isolated nocturnal desaturation in COPD: prevalence and impact on quality of life and sleep
TLDR
Nocturnal desaturation was common in patients with COPD with resting saturations ofLess than 95%, but was estimated to have a prevalence of less than 5% in the whole outpatient population, and was not associated with impairment of HRQL, sleep quality or daytime function.
Impaired Sleep Reduces Quality of Life in Chronic Obstructive Pulmonary Disease
TLDR
The data suggest that quality of sleep is major determinant of HRQL in COPD, and increased efforts to diagnose and treat sleep problems, including measures to improve factors that adversely affect sleep should receive great attention in the daily management of these patients.
Frequent sputum production is associated with disturbed night’s rest and impaired sleep quality in patients with COPD
TLDR
The results indicate that objectively measured body movements during night’s rest like body postures and transitions are not related to sleep quality in patients with COPD, and an association between frequent sputum production and disturbances during night's rest and sleep quality is found.
Temporal relationships between physical activity and sleep in older women.
TLDR
These findings suggest that nightly variations in sleep efficiency influence physical activity the following day, and improving overall sleep quality in addition to reducing nightly fluctuations in sleep may be important for encouraging a physically active lifestyle in older women.
Poor sleep is associated with poorer physical performance and greater functional limitations in older women.
TLDR
Objectively measured poorer sleep was associated with worse physical function and the underlying mechanisms for the association between poor sleep and functional decline were not identified.
Night-time symptoms: a forgotten dimension of COPD
TLDR
Night-time symptoms in COPD are prevalent and bothersome and emerging data suggest that bronchodilator therapy can improve them if deployed appropriately, and further clinical investigation with validated tools is needed.
Sleep disorders in COPD: the forgotten dimension
TLDR
Sleep in chronic obstructive pulmonary disease (COPD) is commonly associated with oxygen desaturation, which may exceed the degree of desaturation during maximum exercise, both subjectively and objectively impairing sleep quality, and management of sleep-related problems in COPD should particularly focus on minimising sleep disturbance.
