Our bodies are pretty impressive entities. They’re full of diligent cells, untiring bacteria and industrious electrolytes that work around the clock to keep the machine well-oiled and ticking along according to plan. To function properly, of course, our bodies need fuel. That fuel comes in the form of nutrients from food, from sleep, and from water. If your body loses water, and doesn’t fill it back up – things start to get a bit problematic.

When you work out, for example, you can lose around 1.5 liters (about 6 full glasses) of fluid per hour – which is a helluva lot when you consider that you have about 5 liters of blood in your body in total!

But you don’t have to be exercising to be losing fluid. You lose it simply through sweating and the normal functions of your respiratory system. And when you sweat, you lose electrolytes – which are absolutely vital for proper cell function.

If you lose too many fluids, you become dehydrated – which leads to feeling tired and fatigued, lightheaded, and gives you those much dreaded muscle pains and cramps. THIS is why you need to drink at least 2 liters of water a day to keep hydrated and healthy.

But there are also other, more noticeable things that will happen when you start drinking more water. Get your 8 glasses a day in and you’ll reap these benefits:


By cleaning your liver, water can eliminate the cause of acne and breakouts – and help prevent and decrease the appearance of wrinkles.


If you’re lucky enough to live in a country with clean, healthy tap water – it has added fluoride that gives your pearly whites (and your bones) extra strength and density.


No one likes achy joints. If your body dehydrates, less synovial fluid is there to protect the joints from pain and damage.


Did you know that water is crucial for nutrients to absorb properly? It also helps with lots of other chemical reactions in the body – like optimum brain function and memory retention.


Water is essential for a well-functioning digestive system – and is vital to up keeping a healthy urinary tract. To properly metabolize food, water is critical – and even helps reduce constipation.


Recent studies have shown that an increase in water intake actually works to reduce fat deposits. Drinking lots of water can also be a natural way to suppress the appetite, help with metabolizing stored fat, and leads to less consumption of sugary drinks like soda.


Although water doesn’t directly give you burst of energy like, say, carbs do – it does play a very important part in your body’s energy levels. It’s where all your energy reactions will happen – and if you don’t drink enough water, you’ll become fatigued and lethargic.


Your muscles need electrolytes to be able to function and not cramp. Because muscles are mostly water, dehydration can stop them from properly flexing and contracting – leading to decreased muscle tone.
