Many folks find it difficult to drink the usual recommended eight 8-oz glasses of water daily. That makes me wonder if there’s an underlying evolutionary mechanism at play, and maybe we don’t need that much water. Drinking untreated water exposes us to disease-causing organisms. The more water, the more pathogens.
I quote MNT:
“But how much water do we need to drink on a daily basis?
While you may have heard that eight 8-ounce glasses of water each day – known as the “8×8 rule” – is the aim, there is no scientific evidence that pinpoints precisely how much fluid is the optimal amount.
Based on studies to date, the Institute of Medicine (IOM) recommend that women should aim to drink around 2.2 liters of total beverages daily (around 9 cups), while men should aim to consume around 3 liters of total beverages daily (around 13 cups).
However, contrary to these recommendations and the so-called 8×8 rule, the new study suggests we should only drink when we are thirsty, after discovering a mechanism that makes drinking excess water challenging.”
