Hopefully this would put this medical myth to bed once and for all.
It’s a medical myth that one needs to drink 8 glasses of water per day. Okay then, let us go back to the person who told you that you aught to drink 8 glasses of water in a day. You won’t find it in any scientific literature.
The origin may be found here: in 1945, the food and nutritional board of the natural research council recommended and I quote: “A suitable allowance for water for adults is 2.5 Liters daily in most instances. Most of this quantity is contained in prepared foods.”
So now here’s where people went wrong. They focused on the first part of the message and forgot to quote the second sentence in that message. Hence, the message was now understood/misunderstood to imply one drink an
additional 2.5 liters (8 glasses) of water a day and ignored the part that spoke of these water is mostly contained in the food/drinks we consume in our normal day.
Now that does not mean one does not need any additional water during the day if for example a need is warranted. This need could arise due to exercising intensely and perspiring profusely due to whatever circumstance.
