Wellness has become so encompassing that seemingly anything can be mined for the purposes of living better. There are walking coaches — I have been to more than one — and self-appointed experts who can teach you how to breathe more effectively. Some people are even seeking out that humblest of minerals, salt.

I love taking baths, even in the narrow tub in my apartment, and hoard various salts that I pour into hot water after working out: Dr. Teal’s or, if I’m willing to spend $18 on a single-use blend of hand-harvested French gray sea salt, wild-harvested seaweed and sustainably farmed spirulina, I’ll buy Pursoma Minerals de Mer body soak.

Now you can inhale your way (supposedly) to better health with salt rooms, where the act of breathing in sodium chloride is said to help asthma, arthritis, allergies, snoring and that catchall, “stress.” Adherents of halotherapy (as it’s called) believe that salt has antibacterial, antiseptic, antifungal and antiviral properties that are particularly effective on mucus and inflammation.
