I know it may sound crazy, but it's a serious question, because it really feels like I am being spied on. I also have an approximate idea why but I want to hear if you can confirm it, and maybe you can even tell me more about it? What do you guys feel? And do you have any sense of what I can do to stop the spying? Or do you just feel like I am crazy? I prefer not to show my face as often as I can on reddit, so I hope a picture from my apartment is enough ? (Possibly I can show a picture of me in the comment section or to someone's private chat, in case I have to)
I don't really understand the thing with the setting of Hz. For instance how much Hz should you set if you are going to do red light therapy on your back? Or on your scalp? You can choose the following: 10, 40, 100, 300, 500, 800, 1000, 1500, 2000, 2500, 3000, 3500, 4000, 4500, 5000, 5500, 6000, 6500, 7000, 7500, 8000, 8500, 9000, 9500, or 9999.
It says to keep the device 1-5 cm from the skin, Or rest it directly against the skin. You can choose red, NIR or both. 660 nm - 850 nm. 10 - 20 minutes per session. You can also choose intensity : 25%, 50%, 75% or 100 %
