Light therapy may also benefit psoriasis, a skin disease that causes red, itchy scaly patches. Unfortunately, psoriasis is a chronic disease with no cure. Sufferers typically go through cycles and experience flare-ups every few weeks or months. Luckily light therapy may help.
WebMD says the nbUVB light from a light box or laser may help “slow the growth of skin cells, calm an overactive immune system, and ease inflammation and itching.” The source also notes PUVA light therapy may also help treat psoriasis.
Is Light Therapy Right for You?
While light therapy alone won’t cure the conditions we mentioned above, it can be a helpful tool in improving some of your symptoms. Keep in mind, it can take a few days up to a few weeks to start to notice the effects so don’t give up after a few sessions.
Light therapy is generally safe but it’s always a good idea to talk to your doctor first before starting any new form of treatment. However, you should definitely err on the side of caution if you have a condition or take medication that makes you sensitive to light.
Things to Consider When Choosing a Light Therapy Device
There are many light therapy boxes on the market from online shops to drug stores. Do your research and work with your doctor to find the right one for you.
One important thing to consider when choosing a light therapy device is the intensity. The Mayo Clinic says, “the intensity of the light box is recorded in lux, which is a measure of the amount of light you receive.” For example, the source says a 10,000-lux device is typically recommended for SAD.
Each session is usually about 20 to 30-minutes but a device that has a lower intensity may require a longer session. This is why it’s important to work with your doctor to find the right device for you and your condition.
