Far Infrared Sauna and POTS

the majority of the research i did on infrared saunas pointed towards near infrared being the preferred type for health benefits

the names are references to the wavelength of the light emitted
which pretty much correspond to the light sources used - incandescent bulbs, heat mats, etc
near infra red are nearest to visible wavelengths
far infrared are furthest from visible wavelengths

it turns out NASA funded a good deal of the original research into this stuff - and there is some real science behind some of the benefits - but from memory they did most of their research with Laser diodes etc so they could control the light frequencies.
one thing that surprised me is that they demonstrated that there are receptors on our cells that react directly to infrared light - was entirely new to me.

this site that sells high end boutique style products has some interesting pages on the scientific studies - but since there is an industry around it i am sure you will also find other manufacturers who use alternative light sources quoting papers to support their marketing claims also.

edit - well they used to - site has been re-written and most of the links are now gone

here is a site that reviews the different types and gives links to studies

as with everything in the health world - absolute truth does not exist - we simply have to make our own view of the claims and counter claims by reviewing both side of the argument in as balanced a manner as you can manage

my view is 90% of it comes down to the light source - the rest is largely fluff, marketing and window dressing - i found the real science studies done by NASA and the clear evidence that Near infra red penetrates the body far more the most compelling.

btw - i made a sauna space sauna copy - using the same bulbs - for around £150 all in

I have sunlighten sauna and it will make your pots worse when you start so take your oximeter in with you and watch your heart rate. Babesia will be the culprit here. You will be toxic after the sauna and I recommend you drink 2 table spoons of lemon juice after you shower to slow your heart rate back down. I use the organic 100 juice no additives in a glass jar. Start the sauna at 10 mins and work up you have high bacteria load so that is the pots issue. When your not killing your pots is better right? You got to detox way more with pots and the reason is Babesia and Bart clog up the red blood cells. When you kill with abc or herbs. My pots improved soooo much with that lemon juice trick.

be aware that infra red sauna is big business and all the companies are basically competing for customer attention and tend to do so by making all sorts of pseudo scientific claims that would have the users believe that ONLY THEIR patented whatsamagic technology can deliver the health benefits they are interested in.

even the claims that are somewhat true tend to mislead by avoiding telling the main part of the story

The truth is every warm / hot object emits a broad spectrum of infra red light suitable for providing health benefits

that is all the sun is after all - a very big hot object that just happens to be a long way away

the fact that we evolved with a sun in the sky is why we respond positively to infra red light - so its basically emulating this that brings many of the benefits - and an inexpensive incandescent heat lamp / bulb does this very well.

so, by all means buy a fancy and aesthetically pleasing $5000 unit if its something you would like to own
but do not be sucked in to thinking only these high price tag items will provide the health benefits we are interested in - that's all just hype.

Buying a sauna was one of the best investments for me. I love the heat and it always feels amazing to me. If you have POTS, it can make those symptoms worse, however. I have it and have to make sure that I stay super hydrated before and after using it. Start slow and on a lower heat and work your way up.
