Following a centuries-old tradition practiced by medieval monks and documented by Greek philosophers, Salt Cave shelters clients in a therapeutic space with walls, floor, and ceiling covered with a fine Himalayan crystal salt. Within, the atmosphere is kept warm, dry, and filled with a salt aerosol to soothe skin and alleviate ailments breathing air similar in consistency to a crisp beach breeze. Calming music and low lights settle nerves as guests sit in comfortable lounge chairs soaking up salty vapor thought to help heal stodgy sinuses, solve skin problems, and cheer up lonely pepper shakers. The chamber is sonically locked and barred to keep out noises and nuisances and features a designated children's area to provide a soothing sabbatical for the whole family.
