A luxuriant sea salt extracted and solar dried from the saline and mineral rich marshes of the confined Dead Sea. Dead Sea salt is a nutrient rich, extremely fine, and partially moist salt perfect for bath products and scrubbing blends. Choose from 3 different sizes.
Infrared (IR) is invisible radiant energy, electromagnetic radiation with longer wavelengths than those of visible light, extending from the nominal red edge of the visible spectrum at 700 nanometers (frequency 430 THz) to 1 mm (300 GHz) (although people can see infrared up to at least 1050 nm in experiments).
Visible light, ultraviolet rays, and X-rays are all parts of the  electromagnetic spectrum, and travel at the same speed. Humans can  see visible light, but not ultraviolet â¦ rays or X-rays. Ultraviolet  rays have shorter wavelengths, higher frequencies, and higher  energy than visible light. X-rays have shorter wavelengths, higher  frequencies, and higher energy than ultraviolet rays.   This means that ultra violet and x-rays can do far more damage to  our flesh than light can.
