The advice to drink 8 cups of water a day has been around for awhile, and while many doctors and patients alike swear by it, it’s nothing more than a made up guideline.
The advice came from a random doctor in 1940 and has stuck around until today, without any scientific merit to back it up.
More recent studies and advice states that you should drink when you’re thirsty, or when sweating/exercising.
Your urine color is a great indicator of your hydration. If your urine is white, you’re definitely hydrated, and possibly even too hydrated if you’re peeing more frequently than every 45 minutes.
If your urine is yellow or orange, you should consider drinking more water to help your body rehydrate.
If your urine is light yellow, you’re in a pretty good spot and could possibly consider drinking an extra glass of water, but don’t need to force water down your throat in order to meet the 8 cups a day guideline.
Listen to your body and observe the signs you see, and make your hydration choices based on your own individual needs.
