Red and infrared light therapy (Red Light Therapy, Photobiomodulation) is a science-based method to improve cellular energy production and the body\u2019s natural healing process. This therapy is often used to improve skin condition, reduce pain, recover from sports and maintain general well-being. Over the past few years, this technology has become extremely popular in Lithuania, the Baltic States and Scandinavia, where natural light is lacking for more than 150 days a year. Such a light deficit affects a person\u2019s energy level, circadian rhythm, skin condition, physical recovery and emotional well-being.<\/p>\n\n\n\n
In this article, we will explain in a simple and clear way the essential points that are of interest to people considering this therapy: what it is, how it works, and how to use the equipment safely and effectively. The information is based on reliable scientific sources \u2013 such as Hamblin (2018)<\/a>, Chung et al. (2012)<\/a> Red and infrared light therapy is often presented as a modern technology, but in fact its principles are not new. For decades, scientists have been studying how light of certain wavelengths affects cells and why it stimulates natural healing processes. This therapy is based on a very simple idea: our body has an innate ability to regenerate, and light can enhance this ability.<\/p>\n\n\n\n Although light therapy is often presented as a modern innovation, its principles have been studied for decades. Scientists are studying how light of certain wavelengths affects cells and why it stimulates natural healing processes. The essence of the therapy is simple: the human body has an innate ability to regenerate, and light can accelerate and enhance this process.<\/p>\n\n\n\n Red light therapy uses diodes with a wavelength of 630-670 nm. This light penetrates to a depth of 5-10 mm and affects skin cells, fibroblasts and superficial blood circulation. It is best suited for skin regeneration, improving elasticity and stimulating collagen synthesis.<\/p>\n\n\n\n Infrared rays penetrate much deeper, up to 30-50 mm. Due to this depth, they affect muscles, joints, bone tissue, peripheral and central nervous systems. This is the same type of light that athletes use to recover faster after intense training.<\/p>\n\n\n\n Characteristics of red and infrared light<\/strong><\/p>\n\n\n\n
