Bright light therapy is used to gradually shift sleeping patterns to what we consider normal. For treatment, the timing of light exposure is critical. For DSPS, the light must be delivered to the retina as soon after spontaneous awakening as possible to achieve the desired effect.
Bright light works by stimulating cells in the retina that connect to the hypothalamus, a part of the brain that helps control circadian rhythms. Activating the hypothalamus at a certain time every day can restore a normal circadian rhythm and thus banish seasonal symptoms.
When you begin light therapy , your first response will show you whether you need to adjust the intensity or duration. Many people respond to light therapy within 3 to 5 days. If you don’t respond to treatment within the first week, you may notice improvement in the second week.
For most people, light therapy is most effective when it’s done early in the morning, after you first wake up. Your doctor can help you determine the light therapy schedule that works best.
Anxiety and depression scores were significantly reduced following the light therapy at T3 in both the high- and low-intensity groups. Conclusions: Light therapy resulted in a significant reduction in symptoms of anxiety and depression but we did not find any differences between high- v. low-intensity treatment.
We tried six additional light therapy lamps in 2020. The Carex Day-Light Classic Plus remains our top pick. The compact Verilux HappyLight Luxe is now our budget pick.
Even though it’s a light -based therapy , sun lamps don’t impact vitamin D production. Be sure to get your vitamin D through your diet and/or supplements as your doctor advises.
The most common side effects of light therapy include: Eyestrain or visual disturbances. Headaches . Agitation or feeling “wired.” Nausea . Sweating.
Abstract. Seasonal Affective Disorder ( SAD ) is prevalent when vitamin D stores are typically low. Broad-spectrum light therapy includes wavelengths between 280-320 nm which allow the skin to produce vitamin D .
Light therapy cannot be overdone for most people. If you notice any extraordinary results, stop treatment, and contact your physician. For the best results, choose the right device style and LED color, and use it as directed.
Experts believe that blue LED light reduces activity in the sebaceous glands, which are small oil-producing glands in the skin . This reduction in activity causes the glands to produce less oil, possibly improving acne symptoms.
Start light therapy in the early morning, as soon as possible after awakening (between 6:00 a.m. and 9:00 a.m.). Response usually starts in a few days, and by two weeks the symptoms should be definitely improving. Most people need to continue light therapy throughout the winter until the springtime.
Don’t look directly at the light box, which will damage your eyes . Although light therapy is generally safe, people with bipolar disorder may become manic after too much light exposure. And people with any kind of retina disease or diabetes are at greater risk for eye damage than others.
Red light therapy (RLT) aims to solve skin issues by using low wavelength red light . Many experts believe that it can help with issues such as skin conditions, scarring, and signs of aging — including wrinkles and age spots. There is some evidence to back up many of these claims, but RLT is no miracle cure.
Light therapy can help relieve sleep issues associated with insomnia , circadian rhythm sleep disorders, jet lag, seasonal affective disorder, and depression.
