Yes, it is possible to overdose on light. Red light therapy follows a biphasic dose-response, where too little light has minimal effect, the optimal dose provides maximum benefits, and excessive light diminishes the positive effects. To avoid overdosing, adhere to the recommended guidelines: position yourself 15 to 50 cm from the light for 10 to 20 minutes per area. Monitor your individual response and adjust the distance or session duration as needed. Everyone's sensitivity to light varies, so it's important to find the balance that works best for you.
