According to Watson's Human Care Theory, an improved environment influences patients' care processes. The purpose of this study was to examine the effect of an improved environment, according to Watson's Human Care Theory, on sleep quality, anxiety, and depression in patients undergoing open heart surgery. Upon admission to the ward from the postoperative intensive care unit, the experimental group underwent environmental remediation for three days.

Timing and architecture of sleep are co-driven by circadian rhythms modulated by their major Zeitgeber light and darkness. In a natural environment, one is exposed to 3.000 lx (cloudy winter sky) to 100.

Low indoor light in urban housing can disrupt health and wellbeing, especially in older adults who experience reduced light sensitivity and sleep/circadian disruptions with natural aging. While controlled studies suggest that enhancing indoor lighting may alleviate the negative effects of reduced light sensitivity, evidence for this to be effective in the real world is lacking. This study investigates the effects of two light conditions on actigraphic rest-activity rhythms and subjective sleep in healthy older adults (≥ 60 years) living at home.

Sleep-wake disturbances frequently present in Veterans with mild traumatic brain injury (mTBI). These TBI-related sleep impairments confer significant burden and commonly exacerbate other functional impairments. Therapies to improve sleep following mTBI are limited and studies in Veterans are even more scarce.

- The study aimed to assess how a week of extra sleep at home affects the circadian rhythms of adolescents who usually don't get enough sleep.
- Twenty-six participants experienced two conditions: their regular sleep schedule and an extended sleep schedule where they got at least an extra hour of sleep.
- Results showed that sleep duration increased significantly with the extended sleep but did not affect melatonin levels, suggesting the possibility of better circadian alignment that could be enhanced with additional strategies like morning light exposure.
