Personal experience is good. The word SPA comes from the Latin prefix "health brought by water". Solus = health, Por= = essential oil, Aqua= = water, which means to use water to achieve health. The method is to make full use of the physical characteristics, temperature and impact of water to achieve the effect of maintaining fitness. SPA (French solutpor aqua) means "healthy water", while the British leisure culture SPA(Spring pute air) means "enjoying pure air in the mineral spring area". The wonderful smell of SPA has been circulated for hundreds of years, and it was recorded in ancient Greek literature. Adding minerals, aromatherapy, herbs and flowers to water can prevent diseases and delay aging.
