In laser therapy, what is the primary purpose of using a cooling device?

The primary purpose of using a cooling device in laser therapy is to protect surrounding tissue. When lasers are applied to the skin or other tissues, they generate heat as they interact with the targeted area. This heat can potentially cause thermal damage to the tissues surrounding the treatment site. A cooling device helps to mitigate this risk by maintaining a safe temperature in the surrounding tissues, thereby ensuring that only the intended area receives the therapeutic effects of the laser while minimizing damage to adjacent skin and tissues.

This protective function is crucial, especially in procedures involving sensitive areas or deeper tissue penetration, where the risk of collateral damage is higher. By effectively cooling the area, practitioners can enhance patient comfort and improve the overall safety and efficacy of the treatment.
