This light is typically red or near-infrared in color and is delivered through a handheld device that is placed on the skin.<\/p>\n<h3>The Science Behind Laser Therapy<\/h3>\n<p><a href=\"https:\/\/www.newhopephysio.com\/blog\/what-is-laser-therapy\/\" target=\"_blank\" rel=\"noopener\">Laser therapy<\/a> works by using light to penetrate the skin and stimulate cellular activity. This cellular activity, in turn, promotes healing in the affected tissues. Specifically, laser therapy is thought to:<\/p>\n<ul>\n<li>Increase the production of ATP (adenosine triphosphate) in cells, which provides energy for cellular processes.<\/li>\n<li>Enhance blood flow to the affected area, which delivers oxygen and nutrients needed for healing.<\/li>\n<li>Reduce inflammation by decreasing levels of pro-inflammatory cytokines and increasing levels of anti-inflammatory cytokines.<\/li>\n<li>Stimulate the production of collagen, a protein that is essential for tissue repair and regeneration.<\/li>\n<\/ul>\n<h3>Benefits of Laser Therapy<\/h3>\n<p><a href=\"https:\/\/www.newhopephysio.com\/blog\/exploring-the-benefits-of-laser-therapy-in-orangeville\/\" target=\"_blank\" rel=\"noopener\">Laser therapy<\/a> has shown to be effective in treating a wide range of conditions, including:<\/p>\n<ul>\n<li><strong>Pain relief:<\/strong> Laser therapy has used to treat <a href=\"https:\/\/www.newhopephysio.com\/chronic-pain\" target=\"_blank\" rel=\"noopener\">chronic pain<\/a>, including back pain, neck pain, and joint pain.<\/li>\n<li><strong>Inflammation reduction:<\/strong> Laser therapy has shown to reduce inflammation in conditions such as arthritis and tendonitis.<\/li>\n<li><strong>Wound healing:<\/strong> Laser therapy can promote faster healing of wounds, including surgical wounds and ulcers.<\/li>\n<li><strong>Nerve regeneration:<\/strong> Laser therapy may help regenerate damaged nerves, which can be beneficial in conditions such as neuropathy.<\/li>\n<li><strong>Cosmetic applications:<\/strong> Laser therapy has used to reduce the appearance of scars, wrinkles, and stretch marks.<br \/>\nApplications of Laser Therapy<\/li>\n<\/ul>\n<h3>Laser therapy can be used in a variety of medical settings, including:<\/h3>\n<ol>\n<li><strong>Physical therapy:<\/strong> Laser therapy often used as a complement to traditional physical therapy to promote healing and reduce pain.<\/li>\n<li><strong>Sports medicine:<\/strong> Laser therapy can help athletes recover from injuries and improve performance.<\/li>\n<li><strong>Dermatology:<\/strong> Laser therapy used to treat a variety of skin conditions, including acne, psoriasis, and vitiligo.<\/li>\n<li><strong>Dentistry:<\/strong> Laser therapy used in some <a href=\"https:\/\/www.oda.ca\/oral-health-basics\/dental-procedures\/common-dental-procedures\/\" target=\"_blank\" rel=\"noopener\">dental procedures<\/a> to promote faster healing and reduce pain.<\/li>\n<li><strong>Veterinary medicine:<\/strong> Laser therapyused to treat animals with conditions such as arthritis, hip dysplasia, and skin conditions.<br \/>\nRisks and Precautions of Laser Therapy<\/li>\n<\/ol>\n<p><em><strong>While laser therapy is generally considered safe and well-tolerated, there are some risks and precautions to be aware of.
