Great question. I have a friend who has several of these lamps around her house. And she is convinced that they help her fight off allergies and keep her breathing easy. We've also had discussions about Himalayan salt inhalers (https://asthma.net/forums/himalayan-salt-inhaler) and salt caves for the treatment of asthma and allergies in this community. And this subject has also been studied by researchers, although I think the results are, at this point, inconclusive -- some show they help while others do not. You can check out some of these studies if you want by doing a search such as "himilayan salt, asthma, study." Still, it's an "alternative" treatment that is available for those who want to try it. As Leon noted above, this may be an interesting discussion to bring up with your asthma doctor. What do you think? John. asthma.net community moderator.
