10 Warning Signs You Are Dehydrated

Every single cell, muscle, tissue and organ in our body depends on water. When we are properly hydrated, we are energetic and alert. When there is a lack of water circulating in our systems, we can become lethargic and fatigued. Dehydration impedes your body function as it causes electrolyte imbalance. Dehydration also causes low blood pressure and insufficient supply of oxygen throughout your body. This can lead to many system dysfunctions. Can you identify the warning signs that your body needs more water? Let’s take a closer look at how our bodies tell us we are lacking water intake. 

Accelerated heartbeat

Dehyration creates more viscous blood and decreases the volume of the plasma, which leads to a circulation of the blood and accelerated heart rate. Lack of water in the body can lead to alterations in the electrolytes levels in your body, causing accelerated heart palpitations. This is a result of the extra stress on your body from lack of water intake. 

Bad breath and dry mouthdrymouth

When water deficiency occurs in the body, it stimulates the production of saliva. Saliva contains antibacterial properties. Since bacteria proliferates in the oral cavity, you may experience bad breath. Dry mouth can also occur during dehydration as water hydrates the mucus membranes in the throat.

Abrupt food cravings

We often mistake our thirst with hunger. When thirsty, we crave food. During water loss and loss of electrolytes, the body has a great need for salty food. If you suddenly feel the urge to eat something, you should first drink a bottle of water before you get something to eat.

Pain in the joints and muscles

Our joints and cartilage are made of 80% water. You can experience cramps and muscle spasm if your body lacks water. Dehydrated also increases the friction between the bones, which causes painful joints. 

Dry skin and lipsdehydskin

If your body is dehydrated, your skin will be dry. Hydration enhances elasticity of the skin. Another common sign of dehydration are dry/ chapped lips.


Studies have confirmed proper hydration is essential in the prevention of constipation. During dehydration, you can become constipated from the loss of fluids. The lack of water creates a hardened stool. 

Fatigue and lethargy

Lack of water in the brain leads to low blood pressure and insufficient supply of oxygen throughout your body. Therefore, you may experience lethargic feelings or sleepiness. During dehydration, the body needs to enhance efforts to sustain it, spending additional energy. This can cause exhaustion.

Decreased need for urination and changed urine colour

A hydrated body needs to urinate around 4-7 times a day. If you do not urinate this frequently, there is a high chance your body will have increased levels of toxins. In this case, your urine will be a dark yellow or amber-colored. If your body is well hydrated, your urine will appear clear and light. 

Brain fog or poor concentration

If dehydrated, your mood, memory and decision-making skills will be impacted. Water deficiency causes signs of brain fog, which include difficulties in communicating, thinking and focusing, as well as forgetfulness.

Headaches and dizziness

Headaches are caused by dehydration because of the reduced flow of oxygen and blood to the brain. You may experience dizziness and migraines from dehydration due to the decreased amount of liquid which surrounds your brain.
