hi! I read that there are certain infra-red saunas that are safe to use - with no re-absorption. That's all I heard so far about that.

Thanks for the tip on washing immediately afterwards-- I use a garden hose to rinse myself off immediately after cutting our lawn- and I do feel great as I jump into the shower right afterwards and lather myself off from any film. My skins respond best with Natural soaps minus any chemical additives.
