The History of Light Therapy
Light therapy, also known as phototherapy, has been used for centuries to treat a variety of ailments. Ancient Egyptians and Greeks used sunlight to heal various illnesses, while in the early 20th century, doctors used artificial light to treat skin diseases. Today, light therapy is widely used to treat seasonal affective disorder (SAD), insomnia, and skin conditions such as psoriasis and acne.
How Does Light Therapy Work?
Light therapy works by exposing the body to specific wavelengths of light, typically blue or white light. These wavelengths penetrate the skin and trigger a chemical reaction that can affect mood, sleep, and skin health. For example, exposure to blue light in the morning can help regulate circadian rhythm and improve sleep, while exposure to red light can stimulate collagen production and improve skin texture.
