Well, after watching Ben Greenfield and others rave about it for quite sometime now, I’ve taken the plunge and purchased a Joovv for my wife and I to use at our house. Seems like a great treatment for skin, inflammation, sleep, and even, yes, testosterone levels.
Anyone have any experience running this? Will report back once I receive it, might be something worth looking at for the fellas running the protocol to get healthy again currently.
Please keep us posted. I'm curious as to what your experience will be.Quote:

I do it while doing Wim Hof - double benefit, following it up with a cold shower in the morning.
actually made a post about this while back but no bites
didn't get it but I use bright light therapy for when I first wake up
I bought a Joovv a few months ago, but I need to start using it consistently every day. I think it can only help, and the testosterone boosting research looks promising.
Very interesting thread. I encourage you guys to continue sharing your experiences here. I've never used one nor studied it for that matter so real world experience is priceless to share and help other people.Quote:

The Joovv has two wavelength options, so it won’t help maintain a tan during the winter. One is very red (one of the absolute reddest colors the human eye can see) and the other is invisible. The red light is the one that is shown to improve testosterone in the studies that I’ve read - they have done human and animal studies.Quote:

The red light boosted testosterone in rams, but the invisible light caused huge damage to their testicles and no test increase, although they were exposed to it more than is recommenced for humans. But since the invisible light doesn’t boost test and may harm the testicles, I’d stick with the red light.

There was also a study done on men with genital anesthesia from post-SSRI syndrome, and in 20 sessions the red light restored an average of ~40% flaccid sensation and ~20% erect sensation. (It did not restore their orgasms or sexual pleasure.)

There are also studies showing that it can boost testosterone and libido in men with low testosterone, and others showing that it increases sperm counts and motility. So there is definitely something to it.
Awesome. Thank you.Quote:

There are a lot of factors to consider when dosing - as well as the wavelength of the light and the dosage, one must also consider power, which is dictated by both the power of your device and its distance from your body (most manufacturers will provide a guide of energy density at various distances). For instance, most of what I've read suggests that a dosage of, say, 1 Joule over 2 seconds (so a power of 500mW) would not produce the same biological effect as the same dosage over 500 seconds (power of 2mW). Then add to that the confounding factor of the tissue penetration rate/depth of various wavelengths of light, none of which any of the literature I've read seems to agree upon...
I believe the safest way to apply light therapy is, at least initially, to attempt to reproduce dosage methods that were found to be healing in studies, and then perhaps to experiment around that dose based upon your body's response. Most of the studies on mammal tissue suggests 6 joule/cm2 (at the surface - the studies tend not to consider penetration rate), generally applied at a relatively low power over several minutes, to be both safe and effective. I'd encourage anyone interested to read the studies themselves, rather than taking their information from bloggers or salespeople, as I've seen some irresponsibly high dosages suggested due to misinterpretation of the studies/dodgy mathematics - one blogger mistakenly recommends dosages as high as 707 J/cm2 of infrared light for the thyroid, when the authors of the study the blogger cited actually used only 2 J.
That being said, an overdose of red light seems in most cases to simply be ineffective, as opposed to actively harmful, and I don't want to stop anybody from exploring a therapy that may be extremely helpful, as the true method of knowledge is experiment. Ultimately, I think red/infrared light therapy should be reserved for those who have already made some progress or recovered, and have health-barometers such as morning erections to gauge their reaction to it upon, rather than those in the lowest pits of PFS, where it's hard to gauge your bodies' response to any treatment, and who may not realise if overdoing the light therapy is holding them back.
