Since the mid-20th century, the "eight glasses of water per day" edict has been considered common knowledge, but is that really enough? The truth is, there is no magic water requirement that applies to everyone. Each human body is different, along with every lifestyle, so it is difficult to say how much water you should be drinking. With that being said, chronic dehydration is a thing, and it's common!
Chronic low-order dehydration is common among the elderly, and it frequently goes unnoticed. It has become one of the ten most frequent reasons for hospitalization. This is rather sad as it is probably the most easily avoided reason for hospitalization.
