Drinking enough water is something we all know we should do for our brain cognition, proper cell function, immune system support, and much more. But staying hydrated may also “reduce the risk of severe heart problems in the future” according to researchers at the National Institutes of Health. Their preclinical research found “connections between dehydration and cardiac fibrosis, a hardening of the heart muscles.” In general, we are chronically under-hydrated. So how much water is enough? The researchers recommend “a daily fluid intake of 6-8 cups (1.5-2.1 liters) for women and 8-12 cups (2-3 liters) for men.” However, if you are exercising hard, or otherwise sweating heavily, you will need to increase these amounts.
