The Himalayan salt lamp is the most popular salt lamp out there, perhaps because it is associated with health benefits and a soothing glow. But how have they received such a positive reputation among salt lamp users? Their popularity may partly be due to the fact that the Himalayan salt lamp reduces so many allergens and irritants in the home. (These irritants include dust, pollen, and pet dander.) Since the Himalayan salt lamp provides a gentle, diffused light, it can also aid with insomnia and help you to relax and get a good night’s sleep.
