Diagnostic imaging involves traditional radiology, computerized tomography (CT), and magnetic resonance imaging (MRI). Each of these procedures involves assessment, planning, execution, reporting, and verifying results. Present-day technology involves the processing of images by computer software. Reporting involves viewing these images on diagnostic monitors. While the authors contend that there...

Residents of long-term care homes suffer from natural light deprivation and other age-related physical conditions. This includes changes in sleep patterns and a decrease in sleep efficiency. Lack of light exposure negatively affects circadian systems and consequently affects sleep.

A common issue within different subtypes of dementia is nighttime agitation, which often manifests as confusion, aggressive behavior, aimless movement, and general disruption of sleep cycles. Nighttime agitation is the most common cause for nursing home admission, and many medical treatments for the condition only target specific symptoms, sometimes resulting in unwanted side effects for patients.

Exposure to appropriate levels of bright light directly affects human circadian rhythms. The circadian rhythm plays a key role in overall human well-being. Previous research suggests that elderly patients within residential care homes are often exposed to low levels of light, which can result in circadian misalignment and irregularities in sleep/wake cycles.

Hospitalized patients often struggle with sleeping soundly due to various factors that arise within the hospital environment, such as noise, pain, general discomfort, and irregular and inappropriate light exposure. Because sleep is such an integral part of the healing process, healthcare designers should consider different ways to improve hospital sleep conditions.

Light is the major synchronizer of circadian rhythms to the 24-hour solar day. Compared to the visual system, the circadian system requires more light to be activated and is more sensitive to short-wavelength light. For those confined indoors, such as patients or residents in care facilities, the lack of access to daylight, or electric lighting providing a comparable amount, spectrum, distribution, duration, and timing, may compromise their human health and well-being.
