How much water should you drink each day
For a long time, conventional wisdom suggested that we drink 8 glasses of water a day. However, this figure does not have any basis in scientific evidence.[1]
Experts instead advise that each person should drink the right amount of water for their body weight, level of physical activity and the climate.
So if not 8 glasses, how much?
The scientific answer that most healthcare professionals and experts agree on comes from the IoM (Institute of Medicine). The IoM is an independent, non-profit scientific organization and they recommend 2.7 liters of water a day for adult women and the figure of 3.7 liters for adult men. This is generally applicable to adults who have reasonably good health and live a sedentary lifestyle in a temperate climate.
However, there are instances where you may need to drink more water. For example, if you are in a hot climate or take part in demanding physical activity. According to the American College of Sports Medicine, you should aim to add 12 ounces of water to your daily intake for every 30 minutes of demanding physical activity.[2]
Why human beings need that much water
To put it simply, your body cannot function well without the right amount of hydration. This makes sense when you consider that water makes up around 60% of our body weight. The human body has many important functions to perform and needs water to do most of them. For example, your blood needs to carry oxygen to all the cells in your body but it can only do this with water.[3]
Are you drinking the right amount of water?
If you are not drinking the right amount of water, then you are either dehydrated or over-hydrated.
Signs of drinking too little water

This can lead to water intoxication and early symptoms of water intoxication can look like the symptoms of exhaustion and heatstroke.

Quick ways to adjust your water intake
The sad truth is that most people are likely to be dehydrated instead of over-hydrated. In fact, some estimate that as many as 75% of Americans are dehydrated.[4] If you are not drinking enough water then you can remedy this by knowing what your correct daily water intake is and drinking up to that amount. Here are some quick ideas to get more water into your diet:
Infuse your water with fruits and herbs to sweeten the taste if you are a sugar addict. Get a water monitoring app to help you keep track of your water intake. Eat hydrating fruits like cucumber, watermelon and strawberries, which are all over 90% water.

While reading this article, you might have discovered that you need to drink less water. However, if you’ve learned that you need more water, then you can do this simply by flavoring water with herbs, keeping track with an app and eating water-rich fruits like watermelons.
