Question:
What is the wave length of the heat bulbs? They are probably infared bulbs
> and can be very damaging to the skin.
Answer:
Ok, apparently I was confused by the original article's discussion of
"heat bulbs" and "infrared bulbs." Apparently, infrared bulbs, while
much better for saunas than heat bulbs, are also much more expensive.
The heat bulbs referred to in the article are actually just 250 watt
bulbs with a red coating on the glass. So instead of building a
far-infrared sauna, the article calls for building a traditional sauna
with heat bulbs rather than rocks. I suppose this means there is no
radiation risk, but also means I would face the risks of normal
heating as well (i.e., setting my house on fire).
