Drinking water stored in a copper water Vessel has a number of benefits according to ancient Ayurvedic medicine. In particular, water stored in a copper vessel (which is known as ?tamra jal? in Ayurvedic medicine) is believed to help balance the three doshas in your body (vata, kapha and pitta) by gently infusing the water with the positive health properties of copper. Water stored in a copper vessel will also become natural alkaline water, which is believed to help balance your body?s pH levels. Studies have shown that copper is anti-bacterial, supports good health, prevents aging, supports healthy skin, helps maintain cardiovascular health, supports the thyroid, and stimulates the brain. Because copper is naturally anti-microbial, our copper bottles are naturally self-sterilizing and do not require as much cleaning as other water bottles. This makes them great for those with an active lifestyle.
