Dehydration can range from moderate to severe. Here's what severe dehydration can cause within your body:

Confusion/Irritability- If you suddenly feel angry or irritable, it is possible the result may be due to dehydration.

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.

Low Blood Pressure- Dehydration can cause a person’s blood level to drop. The American Heart Association explains, “it is more important to recognize how quickly your blood pressure drops than how low it drops. Keep a record of your symptoms.”

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.”

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

If you notice that your mind is starting to play tricks on you, and you're confused by your surroundings, that should be a quick indicator that your dehydration is severe. Do the best you can to stay focused to either locate help or seek the nearest water supply. For more information on dehydration and how you can avoid it, visit The Active Times.
