Water is one of the 6 essential nutrients, next to carbohydrates, protein, fats, vitamins and minerals. We can live without food for 43 to 73 days, depending on the climate. But we can only survive 3 to 6 days without water.
When we age the system that indicates that our body needs water or food can be disturbed. We don’t always feel the hunger or thirst signs. That’s why a lot of elderly people end up dehydrated or malnourished.
It’s good to keep a water diary for a couple of weeks to know what you actually drink on a day. Coffee doesn’t count, as the caffeine in the coffee stimulates the kidneys and thus makes the liquid leave your body faster.
