I bought my Vivarays after my son’s introducing them to me. My hope was to help with some sleep maintenance issues that had gotten worse with increased stress. I do a lot for my health - nutrition, meditation, gratitude practice, neurofeedback, photobiomodulation, exercise/movement, PEMF, etc! And I LOVE my Vivarays!! Although my behaviors aren’t fully aligned with my circadian rhythms at this moment, when I put on my Vivarays in the evening, I get a perceptible shift to calmness and softness and “downshifting” in my nervous system. I have also been able to markedly decrease the number of night-time awakenings and time to go back to sleep, within just the 1st few weeks of getting my Vivarays. It has also been during a very stressful time of the year (which just speaks even more highly of the effects)! Thank you Vivarays!!
