How much water should I drink daily?

Falling upwards

Several years ago, the common advice was 6-8 cups of water a day. Lately, I’ve been hearing 8-10 cups a day. Thankfully, there’s a easy formula you can use to calculate the amount you need.

½ * bodyweight = x ounces of daily water

I didn’t come up with this on my own. It’s a formula you can find on the Hippocrates Health website. So let’s see, for my 160 lbs. body, I’d need 10 cups of water per day.

½ * 160 = 80 ounces / 8 = 10 cups of daily water

For those of you on the metric system, 1 ounce is about 25.6 ml, and 8 ounces (1 cup) is 237 ml (or a little more than a quarter liter).

For my needs, that would work out to 2.36 liters per day. It’s really not that much, particularly on these hot summer days. The sad thing is I’m not drinking enough, and then I end up with these monster headaches. The lack of water may not be the main reason, since I’ve got plenty of other things going on, but it sure is one of the contributing factors.
