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.
Consider when and how often you use it. Many experts recommend using a SAD lamp first thing in the morning. Your doctor might also recommend that you use it during the day. Keep in mind that more is not always better. Overuse of a SAD lamp can produce insomnia or other side effects.
Unlike other types of light therapy , LEDs do not contain ultraviolet rays. Therefore, they’re safe for regular use. LED light therapy doesn’t cause burns compared to other anti-aging treatments such as chemical peels, dermabrasion, and laser therapy . It may be safe for all skin colors and types.
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.
With a 10,000-lux light box, light therapy typically involves daily sessions of about 20 to 30 minutes. But a lower-intensity light box, such as 2,500 lux, may require longer sessions. Check the manufacturer’s guidelines and follow your doctor’s instructions.
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.
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 .
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.
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.
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.
Red light therapy is generally considered safe, even though researchers aren’t exactly sure how and why it works. And there are no set rules on how much light to use. Too much light may damage skin tissue, but too little might not work as well.
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.
Can I get light therapy with my eyes closed ? The positive effects of most light therapy studies have been done with the eyes open. The standard 10,000 lux for ½ hour session assumes your eyes are open.
Most people can use light therapy safely. The recommended light boxes have filters that remove harmful ultraviolet (UV) rays, so there’s no risk of skin or eye damage for most people.
The truth is, light therapy can cause eye damage. “Eyes should always be protected,” says Shamban. (Shamban also advises patients to keep their eyes closed during the treatment, even while wearing goggles .)
