Hi Mimi, and thanks for this post. I see you posted something similar, as part of another conversation, elsewhere on our COPD.net platform, for which the community responded. I do hope you have an opportunity to look over that entire conversation. For your convenience, here is a link to the conversation: https://asthma.net/living/warmer-climate#comment-448285.
As for your current concern - there have, in fact, been a number of articles published about Himalayan salt lamps and salt therapy within the community. Here is a link to an article, by one of our advocates, Lorene, using the pseudonym here of Ms. Al Veoli, which I thought you might find helpful to read: https://asthma.net/living/warmer-climate#comment-448285.
As well, we have some material published on our sister site, COPD.net, which focuses on this type of therapy as well. Here is a link to several of those articles: https://copd.net/search?s=himalayan%20salt.
I do hope you find the information is helpful in a practical way.
Please do keep us apprised of your progress and you move forward with your appointment.
Wishing you well,
Leon (site moderator asthma.net)
