What Is A Sunset Light Projector?

A sunset light projector, also called a SAD lamp or light therapy box, is a special light that mimics natural outdoor light. Light therapy, also sometimes called bright light therapy, is an effective treatment for seasonal affective disorder (SAD).

SAD is a type of depression that occurs during the fall and winter when there are fewer hours of sunlight.

The light from a sun lamp is believed to have a positive impact on serotonin and melatonin. These chemicals help control your sleep and wake cycle. Serotonin also helps reduce anxiety and improve mood. Low levels of serotonin have been linked to depression.

Do I need a prescription for a sunset light projector?

No prescription is necessary for a sunset light projector. Sun lamps are available at many retail stores for a variety of different price points. 

If you are considering trying sun lamp therapy, it’s a good idea to talk to your doctor about whether it’s right for you. If you do decide to buy one, look for a sun lamp with bright, white light.

How do sunset light projector work?

People need exposure to sunlight for many reasons. Sunlight helps the brain make the hormones that the body needs to function. The skin also uses sunlight to make vitamin D.

Sun lamps or light boxes work by imitating sunlight. Experts advise people who wish to try light therapy to use only sun lamps that emit fluorescent light with no ultraviolet (UV) wavelengths.  

However, for people using a sun lamp to help their skin make vitamin D, UVB light is essential. Anyone considering using a sun lamp should speak to their doctor first.Top of Form
