What is light therapy?
Phototherapy, another name for light therapy, is a type of treatment where you are subjected to artificial lighting. The main condition treated by the therapy is seasonal affective disorder, also referred to as major depressive disorder with seasonal patterns (SAD). This particular kind of depression typically manifests itself in the winter. Other problems, such as sleep disorders and other forms of depression, are also treated with light.
METHOD
How it works?
Light therapy is typically used to make up for the loss of sunlight exposure that is assumed to be associated with seasonal variations in major depressive disorder. There will be a light box next to you that emits bright light. There may be differences in the brightness, but it generally resembles natural sunlight. The amount of light utilised in a therapy is measured in units called lux. A light box's typical output ranges from 2,500 to 10,000 lux.
Fall is when treatments often start and last until early spring. Typically, sessions run between ten and fifteen minutes. The intensity of the lightbox and your ability to tolerate the treatment will determine how long the session lasts. A person unfamiliar with the technique can receive shorter initial treatments. Treatment sessions can be shortened using a more potent lightbox.
The reasons why light treatment works are currently being investigated. One theory holds that serotonin is naturally produced in the brain in response to light. The "feel-good" brain chemical is called serotonin. Some specialists think that the placebo effect is to blame for the effectiveness of light treatment.

EXPERT OPINION
What the expert says?
Moline, Illinois psychologist Dr. Carl Vincent recommends combining light therapy with other forms of treatment like psychotherapy or medication.
According to Vincent, "the idea is that it could be used as supplemental therapy." "Those experiencing depression in the winter should strive to increase their level of activity in addition to receiving treatment. People tend to be more inactive in the winter, thus increasing activity can help elevate mood.
TAKEAWAY
