Feeling ill with a cold or cough and looking for a natural way to speed healing?
Try Halotherapy also known as a Himalayan Salt Room.
You'll most likely change from your street clothes into a robe and barefoot you'll enter a salt room for 40-60 minutes. You can lay on the ground on a bed of salt or sit in a chair with your feet in the coarse salt while inhaling micro-particles of salt. Those micro-particles will enter your body and cleanse the upper respiratory tract. You might notice you cough a little more after your session but that is your body cleaning out your mucus or infection.
Obviously if you are very ill or with a fever you'll need to wait so you don't infect others and you'll want to see your doctor to make sure it is not something more serious.
