The amount of water we need to drink each day varies depending on our age, activity level, and environment. However, a good rule of thumb is to drink eight glasses of water per day. If you are not sure if you are getting enough water, check the color of your urine. If it is dark yellow, you are probably dehydrated. Clear or pale yellow urine is a sign that you are well-hydrated.
Drinking water is essential for good health. By staying hydrated, you can help your body function properly and prevent a number of health problems.
