Microbiomes and gut health
Near infrared wavelengths can improve the quality of the bugs in the gut
There is evidence that both red and near infrared wavelengths can improve the quality of the bugs in the gut, and these in turn can change the way that the brain works. It seems weird that bugs in the belly can communicate with the brain, but it definitely is a thing, thanks to the Vagus nerve.
The TheraPad is the best device to use, alternating between the red and near infrared settings. Drape it over the abdomen for twenty minutes once daily, and alternate the wavelengths on a daily basis. If you forget which one you used yesterday, it is no drama. The good bugs in the gut respond happily to both wavelengths.
