Outward signs of growing older, such as wrinkling and withering, reflect what is happening inside the body. At the cellular level, growing older can cause a shift in the ratio of water inside versus outside the cells, because the body’s water content tends to decrease with age. This can decrease energy levels. As the volume of water inside the cells is reduced, the cells wither. This can cause brain tissue to pull away from the skull—something that has been linked with dementia. Water does not activate your digestive system in the way that drinking juice or soft drinks or sugary beverages do. Water hydrates brain and body, lowers your risk of dehydration, and gives your digestive system a rest. Make pure water your primary beverage and choose to love drinking it.
