Red Light Therapy for Thyroid Health
Red Light Therapy for Thyroid Health A Scientific, Clinical, and Practical Review Red Light Therapy (RLT), also known as photobiomodulation , is a non-invasive therapeutic approach that uses specific wavelengths of red and near-infrared light to influence cellular function. Over the last two decades, RLT has been studied in diverse medical fields, including wound healing, musculoskeletal pain, neurological disorders, dermatology, and mitochondrial dysfunction. More recently, interest has emerged around its potential role in thyroid health , particularly in autoimmune and functional thyroid disorders. The thyroid gland is a small, butterfly-shaped endocrine organ located at the front of the neck. Despite its size, it plays a central role in regulating metabolism, energy production, thermoregulation, cardiovascular function, neurodevelopment, and overall hormonal balance. Thyroid dysfunction affects hundreds of millions of people worldwide and is often chronic, lif...
