How effective is the light therapy of depression?
Light therapy is very effective in the treatment of depression if depression is related to seasonal affective disorder (SAD). Most people who experience this depression find relief with the therapy of light. It is the preferred treatment of sets because it is well tolerated, does not require a prescription and is easily accessible. Although light therapy of depression is as effective as treatment in the treatment of SADs, there are no convincing studies that show that light therapy works with other forms of depression.
In some people, lower seasonal light levels may lead to orchards. Shorter days of autumn and winters can disrupt the natural circadian rhythm of the body, 24 -hour clock of the body that regulates sleep and awakening. Disruption of circadian rhythm can cause sleep and depression disorders. Light therapy Depression helps the body regain its natural circadian rhythm, allowing normal sleep patterns and eliminating depression. Other forms of depression, drought as clinical depression, pre-lamstruating syndrome and bipolar disorder are not caused by disruptionCirkadian rhythm and seems to be influenced by light therapy. The light intensity is measured by lux, with bright sunlight measuring 10,000 lux. Sunbar beds and household lights do not radiate high enough luxury or the right type of light and are not efficient.
portable light boxes, made for light therapy, can achieve 5,000 lux and provide the best light intensity for therapeutic purposes. Fluorescent lights "Cool White" produce less ultraviolet radiation than the lights full of spectrum, and although they produce less luxury, they can be useful in light therapy. The 30 -minute 10,000 lux exposure is equal to 5,000 lux exposure.
Most people have found that light therapy for depression is the bridge effective when using during the morning hours, although it sometimes works better in the afternoon or early in the evening. The natural circadian rhythm of each person is different, so the amount of lUXU and the exposed time must be adapted to a specific person to achieve the results. Most people may eliminate depression -related depression within a few days of using light therapy, although some people may not see relief for three or more. In all sad patients, depression returns when light therapy is interrupted. Each responds differently to the amount of lux and to the time exposed to light, so the use of light therapy for depression should be monitored by a doctor.
