Always have a drink nearby for elderly people; all fluids matter. Additionally, serve items like soups, smoothie, popsicles, and fruits like melon and grapes that are high in water content. A lot of fruits and vegetables have a water content of 90% or higher. Seniors can sip hot beverages like chocolate, coffee, and tea during the winter. It can be quite beneficial to have a caregiver around encouraging the elder to drink enough fluids.
