A person is exposed to certain types of light for a certain period of time during light therapy. Light therapy may be used to treat a range of skin conditions, along with seasonal affective disorder (SAD).

What is seasonal affective disorder?

Seasonal affective disorder, also called “winter depression” or “winter blues,” is a type of depression linked to seasonal changes. Major depressive episodes characterize this disorder during the winter and remission during the spring and summer months.

The body’s internal clock signals the down-regulation of several functions during the shorter days: sleepiness, hunger, digestion, etc. The endocrine system, which regulates our hormones, automatically responds to compensate for these deficits. However, some individuals are not able to cope with these changes, which makes them feel depressed. The good news is that phototherapy is very effective in treating the seasonal affective disorder.

How Does Light Therapy Treat Depression?

Did you know that light therapy is a good way to treat depression? Light therapy is a form of treatment that involves artificial or natural light to treat seasonal affective disorder. Light therapy consists of spending around 30 minutes in front of a light source each day. This allows the patient to be exposed to higher levels of light than just sunshine. It isn’t a cure, but light therapy can be beneficial in treating depression. Light therapy is useful in the treatment of anxiety disorders and bipolar disorder.

How SAD lamps work?

Full-spectrum light therapy is most useful for SAD. Rather than a specific wavelength, it uses the entire range of visible light. Fluorescent bulbs, such as those in most lightboxes, are the most common light source capable of providing full-spectrum light. Light therapy helps elevate mood and energy levels by boosting serotonin levels in the brain. The lightbox must be located about a foot away from the face to be effective.

The lightbox’s artificial light can boost serotonin levels and make you feel happier and more energetic. A SAD lamp is designed to provide extra-bright light: most commercial lightboxes are considerably brighter than a typical household lamp.
