Can PEMF or Cold Laser be used on head and tyroids? What are the differences in placement between PEMF, Cold Laser and Contact?

PEMF creates a pulsed electromagnetic field. The strength that the generator can produce is safe to use on the head.

Cold Laser does work by the frequency of the light emitted. Spooky2 uses 650nm red lasers. This wavelength has a frequency of 461,219,166,153,800 Hz. It is safe to use on the head with one caveat. Because it is a laser which is coherent light, the intensity of the light is far brighter than it appears. It can damage the eyes if exposed. So take measure to protect the eyes.

TENS literally stands for Transcutaneous Electrical Nerve Stimulation. It was originally designed to stimulate nerve and muscle tissue, and not to apply rife frequencies per se. The TENS resonation effect happens at low frequencies (below 20,000 Hz) and is why sometimes frequencies can be felt. It is not safe to use above the head due to the potential to cause harm if used incorrectly. If one were to use the right frequency and intensity, they could seize the muscles around the carotid artery and be unable to turn the device off before passing out for instance. For those who know what they are doing it actually can be used on the head. Just the consequence of applying current to the head can have serious consequences if done incorrectly.
