Lasers have evolved and improved over the last few decades. They have expanded from “hot” surgical lasers such as CO2 designed to cut tissue, to the therapeutic lasers used in many clinics around the country. However, there are still many myths about what a laser is, how a laser works, and how much energy is needed to induce biological effects to relieve pain, reduce inflammations, and initiate tissue repair. Below we examine six of those myths.
- There is only one wavelength that is therapeutic
- Laser wavelengths must be between 390 nm and 761 nm
- All it takes is one photon to heal
- Infrared lasers must be ‘hot’
- Light therapy is the same as laser therapy
- Cells can be injured by higher energy density
