5 Ways Dehydration Harms Your Body

Water makes up around two-thirds of the human body


Did you know: Water makes up around two-thirds of the human body? That being said, it plays a huge role in the way your body functions. It keeps you healthy, promotes proper digestion and even eliminates toxins.

Dehydration is a condition in which water depletes the body of vital fluids that help the body function properly.  It can cause dry mouth, extreme thirst, fatigue, loss of appetite and headaches. But it gets worse than that, severe dehydration can be extremely dangerous.


Severe dehydration can cause…

1. Confusion/Irritability- If you suddenly feel angry or irritable, it is possible the result may be due to dehydration. “Researchers from the University of Connecticut’s Human Performance Laboratory found that even mild dehydration alters a person’s mood, energy levels and mental function (Huff Post).”

2. Low Blood Pressure- Dehydration can cause a person’s blood level to drop. The American Heart Association explains, “if you have gotten dehydrated, have low blood sugar or have spent too much time in the sun or a hot tub, it is more important to recognize how quickly your blood pressure drops than how low it drops. Keep a record of your symptoms and your activities at the time your symptoms occurred.”

3. Racing Heart Beat- Dehydration causes your heart to speed up as an attempt to pump the proper amount of blood your body needs to function.  Also, considering dehydration can lead to a multitude of symptoms, an individual’s racing heart beat can be due to anxiety and fear.

4. Fever- Fever and chills are common when experiencing dehydration. Make sure to seek a doctor if your fever rises over 101°F. 

5. Muscle Cramps- Muscle cramps are caused by contracted muscles that refuse to relax. Active explains, “reductions in fluids cause nerve endings to be squished together, overexcited, and spontaneously discharge. That spontaneous discharge is a muscle twitch, which can lead to a muscle cramp.” Constantly drink fluids to avoid abnormal muscle cramps.
