Light therapy is a treatment that involves exposure to a specific type of light, typically bright white or blue light, to help regulate mood, sleep patterns, and overall well-being. It is most commonly used to treat Seasonal Affective Disorder (SAD), a type of depression that occurs seasonally, often in the winter months due to reduced sunlight exposure. Light therapy is also effective in addressing sleep disorders, jet lag, and improving energy levels. The light used in therapy mimics natural sunlight, helping to reset the body’s internal clock, regulate circadian rhythms, and boost serotonin production. Light therapy devices, such as light boxes or lamps, are typically used for a set period each day, usually in the morning, to maximize benefits.
