Made of a salt crystal, it is a natural air ionizer that effectively boosts the number of negative ions in the air. The effect of air ionization by salt stems from its physical and chemical properties. In salt lamps, the ionization effect is additionally enhanced by heating the salt crystal with a bulb installed inside the lamp. Now you can breathe easy and enjoy the beautiful and soothing color of your salt lamp.Long term scientific research into the effects of salt mine microclimate on human health resulted in establishment of underground sanatorium.One of such places is the underground health clinic in the Wieliczka Salt Mine near Cracow. At depth of 250 meters, salt walls and slings saturate circulating air with sodium chloride (10 to 30 mg/m3), magnesium, manganese, and calcium. Steady temperature (14-17°C), high pressure and humidity as well as absence of pollutants constitute the curing properties of crystal salt. They have long been recognized and used in treatments of allergies, respiratory and blood system diseases as well as rheumatism.Now you can also have a mini "salt mine" or create this "microclimate" in your home, a place where you need it most.
