‘Self-care’ takes a community, say mental health experts

New studies have shown that the performance of students is influenced by the time and duration of daylight in their regular schedules. Designing school facilities to incorporate the right types of light at the right time of day for the right duration may improve student performance and well-being. Similarly, designing lighting systems that maximize the right amount of light at the appropriate time of day for the elderly may help relieve symptoms of Alzheimer's Disease. When those patterns are disrupted, they disrupt the natural circadian cycle.

Circadian disruption may lead to numerous health problems including breast cancer, seasonal affective disorder , delayed sleep phase syndrome , and other ailments. A study conducted in and , documented by Robert Ulrich, surveyed 23 surgical patients assigned to rooms looking out on a natural scene. This study suggests that due to the nature of the scenery and daylight exposure was indeed healthier for patients as opposed to those exposed to little light from the brick wall.

In addition to increased work performance, proper usage of windows and daylighting crosses the boundaries between pure aesthetics and overall health. Alison Jing Xu, assistant professor of management at the University of Toronto Scarborough and Aparna Labroo of Northwestern University conducted a series of studies analyzing the correlation between lighting and human emotion.

The researchers asked participants to rate a number of things such as: the spiciness of chicken-wing sauce, the aggressiveness of a fictional character, how attractive someone was, their feelings about specific words, and the taste of two juices—all under different lighting conditions. In their study, they found that both positive and negative human emotions are felt more intensely in bright light. Professor Xu stated, "we found that on sunny days depression-prone people actually become more depressed. In the dark, emotions are slightly suppressed. However, emotions are intensified in the bright light.

Compact fluorescent lamps CFLs use less power than an incandescent lamp to supply the same amount of light, however they contain mercury which is a disposal hazard. Due to the ability to reduce electricity consumption, many organizations encourage the adoption of CFLs. Some electric utilities and local governments have subsidized CFLs or provided them free to customers as a means of reducing electricity demand. For a given light output, CFLs use between one fifth and one quarter the power of an equivalent incandescent lamp.

Unlike incandescent lamps CFLs need a little time to warm up and reach full brightness. Not all CFLs are suitable for dimming. LED lamps have been advocated as the newest and best environmental lighting method.

A downside is still the initial cost, which is higher than that of compact fluorescent lamps. Recent findings about the increased use of blue-white LEDs may be a policy mistake. The wide-scale adoption of LEDs will reap energy savings but the energy savings may be compromising human health and ecosystems. Light pollution is a growing problem in reaction to excess light being given off by numerous signs, houses, and buildings. Polluting light is often wasted light involving unnecessary energy costs and carbon dioxide emissions. Light pollution is described as artificial light that is excessive or intrudes where it is not wanted.

Well-designed lighting sends light only where it is needed without scattering it elsewhere. Poorly designed lighting can also compromise safety. For example, glare creates safety issues around buildings by causing very sharp shadows, temporarily blinding passersby making them vulnerable to would-be assailants. The World Health Organization in [60] issued a report that noted the effects of bright light on flora and fauna, sea turtle hatchlings, frogs during mating season and the migratory patterns of birds. The American Medical Association in [61] issued a warning that extended exposure to light at night increases the risk of some cancers.

The International Commission on Illumination CIE is an international authority and standard defining organization on color and lighting. Publishing widely used standard metrics such as various CIE color spaces and the color rendering index. Manufacturers of lighting equipment publish photometric data for their products, which defines the distribution of light released by a specific luminaire. The International Association of Lighting Designers IALD is an organization which focuses on the advancement of lighting design education and the recognition of independent professional lighting designers.

Those fully independent designers who meet the requirements for professional membership in the association typically append the abbreviation IALD to their name. They publish a monthly newsletter and organise different events throughout the world.

This certification process is one of three national U. Its members include manufacturers and distributors of stage and entertainment lighting, sound, rigging and similar products and services, and affiliated professionals in the area. They lobby for and represent the interests of the industry at various levels, interacting with government and regulating bodies and presenting the case for the entertainment industry.

Example subjects of this representation include the ongoing review of radio frequencies which may or may not affect the radio bands in which wireless microphones and other devices use and engaging with the issues surrounding the introduction of the RoHS Restriction of Hazardous Substances Directive regulations.

This effect is somewhat substantiated by research conducted by LEAA and by the fact that various communities which have installed improved street lighting in certain areas have reported reductions in the rate of street crime.

This interdependence can lead to collaboration transforming into collegiality, a longer term goal and a more permanent, constructive form of co-existence. Loader traces people's current conceptions about society, organisations and individuals to a metaphorical understanding of mechanistic science, as pioneered by Isaac Newton.

In this conception, people are seen as atomistic individuals, separate from each other and their organisations, whose energies are harnessed only by rigid, bureaucratic structures.
