Himalayan salt has a variety of health properties, though it is widely known for it’s respiratory benefits as it is a negative ion generator which purifies the air. The purification of air through negative ion generation is called hygroscopy. The Himalayan salt attracts water molecules and foreign particles that may be carrying dirt, allergens, mildew and dust. When the salt is heated (on a salt wall or salt lamp) the water molecules are released back into the air free from the pollutants trapped inside.
ALLERGIES: Using Himalayan salt walls or lamps in your bedroom, living room, office or kitchen is a beautiful and highly effective way of purifying your air and decreasing allergens (such as pet dander and pollen) and will help relieve allergy symptoms.
ASTHMA: Those suffering from asthma are even more irritated by air impurities. Using Himalayan salt to eliminate impurities from your common spaces can be very beneficial not only for those suffering from asthma, but other respiratory issues like bronchitis as well.
COUGHING: An overabundance of positive ions in the air can actually have adverse effects on your breathing as they slow down your cilia (the microscopic hairs that line your windpipe), thus preventing them from keeping contaminants out of your lungs. On the other hand, negative ions released by heated Himalayan salt actually increase cilia activity and help your body filter foreign pollutants.
