Is light therapy safe?

The bright lights used in light therapy are extremely safe and there are no indications that light boxes cause any damage to the eye. They produce only a tiny amount of UV (ultra-violet) light - much less than normal daylight - so if you are worried about your skin or have been told to avoid UV, this won't be a problem.

A few people experience side effects but these are usually only mild including headaches, eyestrain, nausea and hyperactivity. This can usually be solved simply by switching off the light and, over the next few days, gradually building up the time you spend in front of it to find a treatment time that works best for you. Others complain of insomnia and often this is down to using the light too close to bedtime.

Lumie advise anyone with major eye problems to consult their specialist before starting any form of light therapy.

Although it's not that common, some children get SAD and it's perfectly safe for them to use a light. Remember that they are electrical devices so younger children should always be supervised. It's certainly not a problem to have the light on whilst there are children in the same room or if they come and sit with you when you're getting your light therapy.

There has been very little research involving babies and light therapy so, to be on the safe side, Lumie recommends you keep them away from close exposure to a light.

All the evidence suggests that light therapy is safe during pregnancy. In fact, some researchers are now looking at using lights instead of drugs to treat depression in pregnant women and those with perinatal depression.
