A health retreat is a place where people can go to relax and focus on their physical and mental wellbeing. It typically involves activities such as yoga, meditation, SPA treatments, and healthy eating. The term 'SPA' is an acronym for 'sanus per aquam, ' which is Latin for 'health through water.' SPA treatments are often used to help people relax and rejuvenate, and can include massages, facials, and other body treatments.
