‘How much water should we drink in a day?’ is not always an easy question to answer.
There’s a lag between the time you get dehydrated and the time you get thirsty. The older we get the lower the thirst mechanism affects us.
Water is a great medium for holding and getting rid of heat, and the average adult will eliminate about 2.5 liters (84 ounces) of water per day. (1.5 liters is released through urine). The food we consume is about 17 ounces of fluid a day. Your urine color should look like pale lemonde when you first wake up in the morning.
If you are drinking about half your bodyweight in ounces of water throughout the day then you are more than likely drinking enough water to stay hydrated. But if you are working out a lot or you weigh a significant amount then the amount of water you should drink could be much different than half your bodyweight in ounces. Drink responsibly!
