Can I ever get too much Far Infrared?

You can never get too much Far Infrared. The body will only absorb what it needs and ignore the rest. Infrared light is part of the Sun's invisible spectrum that easily penetrates human tissue. This allows for a deeper heat, better oxygenation of cells and the sweating out of toxins that are trapped inside tissues and cells. Constant exposure will never burn your skin and can actually reverse the effects of ultra-violet damage to the skin. Far-infrared heat is so safe it is even used in hospitals to warm newborn babies.
