Sit in a salt cave

The Salt Cave clinics (there are 10 in England and Scotland) use dry salt aerosol technology, so a saline solution is evaporated into the air. The salt can loosen mucus, reduce inflammation and clear airways, helping you to breathe better, and particle sizes are calculated specifically to reach the deepest part of the lungs when inhaled. Clinical trials of salt caves from the Journal Of Aerosol Medicine showed an 85% improvement in people suffering from mild to moderate asthma.

Clean your teeth with salt

If you’ve ever had tonsillitis, you may have gargled with saltwater to help reduce swelling and get rid of bacteria. Brands are now utilising salt’s hygienic clout for tooth care. Using sodium-rich flakes rather than traditional dental-care minerals such as fluoride, salt stimulates the production of saliva – and the more saliva in your mouth, the easier it is for food to break down in preparation for digestion. Magnesium aids the body’s absorption of calcium too – and what are strong teeth rich in? Yep, calcium. Try Weleda Salt Toothpaste, £4.95, with peppermint essential oils, so it won’t feel like you have a mouth full of seawater.
