Light therapy, also known as phototherapy, uses specific wavelengths of light to treat various health conditions. Each color in the light spectrum has unique properties and effects, making it suitable for different therapeutic applications. Understanding what each color does in light therapy can help you choose the right treatment for your needs.
How Does Light Therapy Work?
Light therapy involves exposure to artificial light that mimics natural sunlight. This exposure can affect biological processes in the body, such as circadian rhythms, mood regulation, and skin health. The therapy is often used to treat conditions like Seasonal Affective Disorder (SAD), skin disorders, and sleep issues.
