Ultrasound on the Vagus Nerve helps regulate our protective responses. This results in a greater sense of competency and calm. You may have to work with it for a while to notice this effect, which can be subtle, but are long lasting.

You could try using a cream that your skin likes instead of the gel. As long as there isn’t an air gap between the wand and your skin the ultrasound energy will pass through.

Near Infrared is great. I favor the laser systems over the LED panels as I think there is an advantage in a coherent beam over an unphased array (mainly in length of treatment). They usually run $200-$300, and are excellent at managing inflammation. I have quite a bit of experience with vibration as a therapeutic tool. The caveat with mechanical stimulation is that it is pro-inflammatory, which is very helpful to increase the mobility of tissues, but exacerbates the activated repair mechanisms in already inflamed tissues. An example would be a Rheumatoid Arthritic joint where I would use NIR as a home program to get the inflammation more manageable and then use mechanical stimulation to break up the adhesions in the joint. Soreness from mechanical stimulation lasting more than a few hours is the metric I use to inform me that I have overshot. Ultrasound has this same issue and I would be careful with long duration treatments on highly inflamed tissues. Instead I would work the surrounding tissues to improve their mechanical properties, with short forays into the compromised area. Stirling may have a different take on this. A very interesting aspect of vibration in the auditory Hz range is the Solfeggio Frequencies. I think of these as beat/interference frequencies of the MHz waveforms discussed in this Skool and find them quite effective at quickly changing my state. I like to listen to them on speakers so the sound gets into my body.

I love refracted sunlight and spend a good amount of time staring at primary colors refracted from prisms and holographic film. I commonly experience a state change, as if otherwise dormant neural pathways get activated. I play around with Neopixels for this reason and modified my garage door so that my neighbors can get some color in their eyes, too. I believe our indoor, urban lifestyles starve our retinas of the full spectrum of visible light they evolved to process, robbing us of the opportunity to develop our full neurological potential. I would not be surprised if there is a treatment opportunity for OCD/ADD using primary color, as I experience improved self-regulation doing this. It is really unfortunate that UV is dangerous, as such a large portion of sunlight is in the near infrared (50%). Our organism evolved to function bathed in these frequencies, and I think it is likely that many of the pathologies we suffer result from our cells functioning sub-optimally from the chronic lack of this energy input. Living in San Francisco, I feel that I am far enough north to sit in the sun without risk and do so whenever the fog clears. I would note that absorption at shorter wavelengths is very shallow (<1mm), and I guess that the therapeutic effect of Cyan light would be through the retina.
