As you probably know, our bodies consist of over 90% of water, which makes the liquid vital for our health. The muscles and kidneys have over 70% of water, the brain is composed of 76% water, while the lungs contain over 90% of water. This means that we need to keep our water levels in check in order to stay healthy, which can be done by consuming 3 liters daily for men and just over 2 liters for women.

Dehydration is not a simple problem and may even be fatal. It can trigger a variety of problems in your body and serious damage to your organs if left unresolved. This is why it’s important to pay more attention to the signs and symptoms of dehydration which you can see in the list below:

Dark Urine

The usual color of the urine is light yellow to amber – anything out of this range can represent some kind of problem. When we’re dehydrated, the kidneys start releasing toxins, chemicals, waste and old blood cells in our urine, making it darker. Of course, some foods such as beets or asparagus can also paint the urine darker, but if its color changes for no apparent reason, we suggest going to the doctor.

Reduced Urine Flow

In general, we pee 6-7 times per day. However, when dehydrated you can expect reduced urine flow. In this case, you need to start drinking water immediately before bigger problems arise.


Lack of water in the body can lead to constipation. When dehydrated, the body starts “borrowing” water from every organ and body part so it can stay hydrated and this includes the colon as well. No water in the colon results in a harder stool, which can become so hard until you’re constipated. If you’re not able to go to the bathroom for more than 2-3 days, it’s time to visit your doctor.

Wrinkles And Dry Skin

According to doctors dehydration can make your skin weak, dry and brittle and is also one of the main reasons for wrinkles. In order to keep a youthful appearance and keep your skin hydrated and clean you need to drink 2-3 l. of water per day.

Hunger And Weight Gain

Our bodies don’t really know the difference between hunger and thirst. The hypothalamus is the brain part that regulates thirst and hunger. When dehydrated, the hypothalamus can get confused and mistake thirst for hunger, making you eat more often which will definitely lead to weight gain.

Dry Mouth And Constant Thirst

Constant thirst and dry mouth are the two most obvious symptoms of dehydration.


Lack of water in the body means that it’s going to start absorbing water from every body part, leading to the shrinkage of the brain tissue. This will make the brain pull away from the skull and trigger pain sensors which will cause headaches. At the same time, dehydration will also make your blood volume drop down due to the lack of oxygen delivered to the brain, dilating the blood vessels and causing even more painful headaches.


Mild dehydration can cause fatigue as the heart needs to work harder in order to pump blood to all the organs and tissues. So, whenever you’re feeling tired, skip the coffee and just drink more water.

Joint Pain

Water is a lubricant for our joints which keeps them in shape and healthy, so lack of it is sure to cause joint pain. Not enough water in the body will make the joints dry and rob them of nutrients, which will damage the cartilage and cause serious problems.

Weakened Immune System

The lack of water in the body will definitely allow more toxins to accumulate in the blood, resulting in a weaker immune system. This will make you more prone to infections and various ailments.

As you can see, dehydration is a problem which can put your life in danger. In order to prevent the aforementioned problems, drink 8-10 glasses of water and you should be fine.
