Hey Exer's....has anyone ever tried sitting in a salt room or cave? You basically sit in a room and breathe in particles of ground Himalayan salt. It is said to be very beneficial for allergies and other respiratory issues. COPD is on the list of conditions that can be helped with salt therapy. I have gone twice now and both times I have felt better coming out. I have always had issues breathing through my nose. But I'm sitting here right now breathing normally. If you guys have a salt room or cave in your area I highly suggest looking into it.
