What happens if you don't drink enough water?

We all know that it is very important to get enough fluids in a day. However, that is not always easy. Especially when the temperatures are rising outside, it is essential to drink enough, because if you don't, you can get quite a few health problems.

The water in our body is the means of transport for all nutrients, it ensures that it can excrete waste and it regulates the body temperature. Exactly how much fluid you need depends on age, temperature, exercise, food and health. In this article, we'll explain what happens if you don't drink enough water.

What can happen to your body if you don't drink enough? We have listed the consequences for you.

Slower metabolism

In the book The Water Secret, Doctor Howard Murad states that if you don't drink enough water, your metabolism will not function properly. Especially the basal metabolism (the burning of calories without exercise) works much faster and better if you take in enough water. When you are working on losing weight, drinking enough water is really essential. Drinking water alone will not help you lose weight faster. It only works if you combine it with good food, exercise and a healthy lifestyle.

you get a headache

The hypothalamus is a gland in the brain that signals when you are dehydrated. It signals when the blood becomes less watery and makes you feel thirsty. That's why you have such a headache when you have a hangover, for example. Because your body is dehydrated from the alcohol. Your brain also has to work harder when you're dehydrated. Tip! Always keep a bottle of water with you. This way you immediately know how much you drink per day.


Not only does dehydration affect the body, it can also put you in a bad mood, according to a study from Tuft University. Students were asked to exercise intensively for 60 to 75 minutes. One group was allowed to drink water during the training session, the rest were not. The second group turned out to be tired, bad-tempered, tense and negative more quickly.


your skin is the perfect gauge to see if your body is hydrated enough. All anti-aging creams together cannot compete with the effect of drinking enough water on your skin. If you consistently drink too little water, your skin will not only lose its glow, but you will also get wrinkles faster. Another reason to grab an extra glass of water.


Your body provides a consistent body temperature by means of water. When we overheat, we sweat. Sweat is just water you lose. We have to make sure we replenish that water, if you don't replenish this, your body temperature rises. This can make you feel faint and dizzy.

cramped muscles

When you suffer from dehydration, your balance is affected. Too little fluid leads to a low level of sodium and potassium, which in turn causes sore muscles and unexpected spastic cramps. Cramps in the leg, calf, neck, foot or arm are in many cases caused by a poor internal fluid or fluid balance.

you eat more

Several studies also state that one or two glasses of water before a meal helps you feel full faster, so that you eat less.

Your brain shrinks!

This is actually not as dramatic as it sounds, but still: Scientists have found that your brain shrinks if you drink too little. If you don't drink enough water, your body dehydrates and the size of your brain shrinks. Fortunately, this is a reversible process and your brain will return to normal size when you are sufficiently hydrated.
