On the possibility of the patient’s skin overheating during low-intensive phototherapy

This paper proposes a simple mathematical model of heating process of the human skin and adjacent inner layers with the LED radiation used in the prevention and treatment devices for various diseases. The problem takes into account the heat removal by blood flow to the vessels. It is shown that abnormal blood flow due to the compression of tissue can lead to severe heating of the body and its burn. This may result even from using small LEDs of 2,5-30 mW.
