10 Warning Signs of Dehydration You Should Know About

A person can survive just a couple of days deprived of water. Two-thirds of the body weight is made up of water and every organ, every cell and every tissue in our bodies depend on water. Water maintains the body temperature, helps digestion, lubricates the eyes and joints, keeps the skin healthy and helps remove harmful toxins and waste from the body. The number of people who are not aware of the amount of water they lose every day is big and because of that they become chronically dehydrated.

Burn victims, diabetics and athletes are at higher risk of dehydration in comparison to the average person. It is easier to recognize dehydration if one understands the symptoms. Take a look at these warning signs which indicate that your body may be lacking water.


Headaches are a possible sign that the body may be lacking water. When your body is not hydrated enough, there is a reduced amount of fluid around your brain, and this fluid makes sure that your brain does not get damaged every time you move. Your brain might start to push against the skull if there is a reduced fluid. To add, dehydration also decreases the flow of blood and oxygen to the brain.

Poor concentration and brain fog

The brain of humans is consisted of about 90 % of water, so it will certainly show signs if it is dehydrated. Water deficiency in the brain can lead to changes in cognitive functions and in the mood.

Mild dehydration can decrease the short-term memory, psychomotor skill, arithmetic ability, visuomotor tracking, and perceptual discrimination, regardless of age. Additionally, it can cause high energy, anger, exhaustion and confusion.

Heart palpitations

Dehydration directly impacts the heart rate and its performance. If the water content in the body is below normal, there is a reduction in the plasma volume thus making the blood more viscous. This has an effect on blood circulation and increases the heart rate. Moreover, dehydration may put the minerals in your body out of balance, which can lead to reduced blood pressure. Palpitations usually happen if there are low levels of potassium and low levels of sugar in your blood.

Bad breath

Once your body is dehydrated, it produces less saliva, which has antibacterial properties. As a result, more bacteria develops in your mouth, causing bad breath. Saliva also protects the teeth from cavities and decay, by creating a protection barrier surrounding them.

Constipation and similar digestive problems

Water aids in the digestion process and helps your body to absorb nutrients, in particularly water-soluble vitamins like vitamins B and C.

Moreover, it keeps the flexibility of the digestive tract and it keeps it clean. In this way, it prevents constipation and keeps regular bowel movements. Water deficiency can lead to indigestion and heartburn.

Food cravings

When you feel hungry next time, drink a glass of water instead of eating a snack. Your body sends false alarms to the brain sometimes. You may think you are hungry, but in fact you are just dehydrated.

Muscle and joint pain

Your joints cartilage is made of approximately 65 to 80 % water. When there is a lack of water in the body, the bones begin grinding against each other thus causing joint pain. Low magnesium levels caused by dehydration can lead to leg pain and muscle cramps.

Lethargy and Fatigue

Loss of fluid leads to dropping of the blood volume and rising of the blood pressure. The heart needs to expand more energy in order to feed the muscles, the skin, and the brain with nutrients and oxygen. This can cause lethargy and fatigue.

Dry lips and skin

Dry, inelastic skin is a sign of water deficiency. Being the largest organ of the body, the skin requires a great amount of water to stay in good shape. Reduced levels of water cause less sweating and the body is not capable of washing away the surplus of oil and dirt that has piled up on the skin during the day. Besides, dehydration increases developments of psoriasis, eczema and acne. Other sign of dehydration are lips which are dry and chapped.

Dark urine

Kidneys maintain the fluid balance in the body. If the amount of water is normal, the color of the urine should be light to clear yellow. However, if the urine is dark, that is a sign that the kidneys directed the water back into the body in order to balance minerals and blood pressure. Urine which is dark contains toxins and you urgently need to start drinking more water.
