On a biological level, red light therapy works in much the same way as exercise. When you work out, you put temporary stress on the body, and the body responds by repairing itself and becoming stronger and healthier. Red and near-infrared light does essentially the same thing, activating many of the same cell defense systems that exercise does by creating free radicals, which promotes a very low-level inflammatory response.<\/p>\n
But too much exercise can diminish the benefits and even cause negative consequences like extreme fatigue or injury. So, is there also such thing as too much red light? The long answer involves a number of variables and mathematical equations, but the short answer is, yes. You need to have enough exposure to achieve particular results, but too much exposure can actually diminish the benefits. While the chances of \u201coverdoing it\u201d and the potential consequences of doing so are minimal, it\u2019s still good for operators and clients to understand that more isn\u2019t necessarily better.<\/p>\n
