Try the newest spa treatment with these salt cave vouchers for Hull! This unique therapy involves breathing salted air to free your body of impurities. Think about how a clay mask purifies your skin by drawing impurities from your pores. Salt therapy has the same effect on your internal organs; as you breathe in the air, the salt reaches deep into your airways. Impurities are drawn to the salt particles and then exit your body more easily. Salt therapy also sooths your nervous system and is very relaxing! It can also help with asthma, hayfever and sinusitis. Use this therapy to increase your overall wellness. Chill out in the gorgeous surroundings of the salt cave, where the walls and floors are covered in salt deposits. Breathe deeply and relax!
