Light therapies involve the use of specific wavelengths of light to treat various health conditions. Commonly used for conditions like seasonal affective disorder (SAD), these therapies can help improve mood and energy levels. They often utilize bright white light or blue light to mimic natural sunlight, which can be beneficial during darker months. Another form of light therapy is red light therapy, which uses low-level wavelengths to promote healing and reduce inflammation. This type of therapy is often applied in dermatology for skin rejuvenation and in physical therapy to alleviate pain. Overall, light therapies offer non-invasive options for enhancing well-being.
