Therefore, how much water should you drink in a day? At one time, you might have heard of drinking at least 8 glasses of water a day or maybe have practiced it.  However, for some people, that amount could be just enough whereas others can do more than that. Still, some can take an amount less than the 8 glasses.

Experts however say that the amount of water required by your body depends on your body size and weight, your activity level, and the environment where you live. Hence, the 8 glasses a day may not be applicable. One expert mentions that for every pound you weigh, you should drink half an ounce to an ounce of water daily.

Additionally, according to the National Academies of Sciences, an average, healthy adult male living in a temperate climate requires about 15.5 cups  (3.7) liters of fluids daily.

On the other hand, an average, healthy female living under the same conditions will require around 11.5 cups (2.7) liters of fluids daily. The fluids recommended range from water and other beverages and food.

However, the Institute of Medicine suggests for men to drink about 3 liters of water daily, women to consume a little over 2 liters per day. Also, they recommend pregnant women to drink about 10 cups of water daily while those breastfeeding need about 12 cups.

Additionally, you can check on the amount of water you need and if you are drinking enough by checking the color of your urine.

Moreover, you can also know that you are dehydrated when you feel thirsty. Hence, whenever you get thirsty, grab a glass of water and drink it to keep hydrated. Therefore, to prevent dehydration, you can add some water in between your meals, before, during, and after an exercise, or still, substitute your can of soda with a bottle of drinking water.

You can take water in other forms such as vegetable and fruit smoothies, beverages, and fruit juices. Importantly, drinking water is the best way to stay hydrated.

Factors Affecting Water Intake

Some factors also help determine the amount of water consumed by an individual. They include the following;

Participating in vigorous activities such as exercising makes you sweat a lot. Therefore, you need to drink an extra amount of water to compensate for the fluid that is lost. Importantly, you can drink water before, during, and after the workout session.

  • Climate

Those who live in hot or humid environments need to constantly drink water to recover the ones lost when they sweat. Moreover, high altitudes increase the level of dehydration in an individual. This, therefore, calls for drinking an extra amount of water.

  • Health Condition

If you are sick and have a fever, diarrhea, or vomit constantly, your body loses a lot of fluid. To replace the water lost, you need to increase the amount of water you drink. Furthermore, if you are suffering from bladder infections, you will need to control the amount of fluid you take.
