Light therapy is one of several approaches to treating bipolar disorder.

Light therapy uses a lightbox which emits far more lumens than a customary incandescent lamp.

Light therapy can also consist of exposure to sunlight, either by spending more time outside or using a computer-controlled heliostat to reflect sunlight into the windows of a home or office.

Light therapy does not work for everyone.

Light therapy -

Light therapy ( phototherapy ) with a full spectrum lamp or portable visor, usually 10, 000 lux for 30 – 90 minutes at the patient's usual time of spontaneous awakening, or shortly before ( but not long before ), which is in accordance with the phase response curve ( PRC ) for light.

Light therapy generally requires adding some extra time to the patient's morning routine.

Light restriction in the evening, sometimes called darkness therapy.

Light therapy may advance the phase about one to two-and-a-half hours and a small oral dose of melatonin, timed correctly some hours before bedtime, can add about 30 minutes to the ~ 2 hour advance achieved with light therapy.

* Light therapy

Light therapy or phototherapy ( classically referred to as heliotherapy ) consists of exposure to daylight or to specific wavelengths of light using lasers, light-emitting diodes, fluorescent lamps, dichroic lamps or very bright, full-spectrum light, usually controlled with various devices.

Light therapy directed at the skin is also used to treat acne vulgaris, eczema and neonatal jaundice.

Light therapy which strikes the retina of the eyes is used to treat circadian rhythm disorders such as delayed sleep phase syndrome and can also be used to treat seasonal affective disorder, with some support for its use also with non-seasonal psychiatric disorders.

Light therapy for skin conditions like psoriasis use UV-A ( 315 – 400 nm wavelength ) or UV-B ( 280 – 315 nm wavelength ) light waves.

Light therapy has also been suggested in the treatment of non-seasonal depression and other psychiatric disturbances, including major depressive disorder, bipolar disorder and postpartum depression.

Light therapy has been tested for individuals on shift work, and for jet lag.

Light therapy is used to treat cases of neonatal jaundice through the isomerization of the bilirubin and consequently transformation into compounds that the newborn can excrete via urine and stools.

Light therapy either uses a lightbox which emits up to 10, 000 lux of light, much brighter than a customary incandescent lamp, or a lower intensity of specific wavelengths of light from the blue ( 470 nm ) to the green ( 525 nm ) areas of the visible spectrum.

Light therapy is a mood altering treatment, and just as with drug treatments, there is a possibility of triggering a manic state from a depressive state, causing anxiety and other side effects.

Light, especially daylight, is always bad for wine.

* " Absalom, Absalom " is the title of a song on the 1996 Compass CD Making Light of It by singer / songwriter Pierce Pettis, incorporating several elements of the biblical narrative.

Alfheim (, " elf home ") is one of the Nine Worlds and home of the Light Elves in Norse mythology and appears also in Anglo-Scottish ballads under the form Elfhame ( Elphame, Elfame ) as a fairyland, sometimes modernized as Elfland ( Elfinland, Elvenland ).

That which is called Álfheim is one, where dwell the peoples called Light elves ; but the Dark-elves dwell down in the earth, and they are unlike in appearance, but by far more unlike in nature.

Anheuser-Busch uses what is in many jurisdictions a legally-protected mark-of-origin indicating Czech provenance and humorous advertising campaigns to promote Budweiser, such as the " Real Men of Genius " radio and television commercials for Bud Light.

* Light roux: The secret to making a good gumbo is pairing the roux with the protein.

Light interaction is often approximated by the even simpler models: diffuse reflection and specular reflection, although both can be BRDFs.

One of Dublin's newest monuments is the Spire of Dublin, or officially titled " Monument of Light ".

Light incident at a given point in the space downstream of the slit is made up of contributions from each of these point sources and if the relative phases of these contributions vary by 2π or more, we may expect to find minima and maxima in the diffracted light.

The Docklands Light Railway ( the DLR ) is an automated light metro or light rail system opened in 1987 to serve the redeveloped Docklands area of London.

The system is owned by Docklands Light Rail Limited, part of the London Rail division of Transport for London.

Light of composite wavelengths ( natural sunlight ) disperses into a visible spectrum passing through a prism, because of the wavelength dependent refractive index of the prism material ( dispersion ); that is, each component wave within the composite light is bent a different amount.

# Kōmyō ( 光明 ) is a phrase used in Japanese Jodo Shinshu Buddhism to refer to the Infinite Light of Amitabha Buddha.

Light is inverted through a small hole or lens from outside, and projected onto a surface or screen.

In the future, it is expected to be made up of around 10 lines, with some over-capacity expected lines considered to be made Light Metro or Heavy Metro.

Light sent down into a gravity well is blueshifted, whereas light sent in the opposite direction ( i. e., climbing out of the gravity well ) is redshifted ; collectively, these two effects are known as the gravitational frequency shift.

* Jesus is the Light of the World

The battle of Balaclava is noted for its famous ( or rather infamous ) charge of the Light Brigade.

William Gibson ( who wrote an early script for Alien 3 ) seems particularly fascinated: a minor character in Virtual Light, Lowell, is described as having New York XXIV tattooed across his back, and in Idoru a secondary character, Yamazaki, describes the buildings of nanotech Japan as Giger-esque.

The song " Jill ", on the album Blue Light, Red Light ( 1991 ) is about her.
