What is dehydration?

Dehydration is when we lose more bodily fluids than we’re taking in. Water and electrolytes are essential to human physiology and we need to maintain the proper balance of these in our system or we will start to experience symptoms of dehydration.

Why is it important to stay hydrated?

It’s important to stay hydrated throughout the day. Proper hydration improves your mood, boosts brain function, and prevents fatigue. It also helps to keep the skin moisturized, produce necessary bodily fluids, such as tears and saliva, and remove waste through sweat, urine, and stool.

How to tell if you’re dehydrated

When we are dehydrated, we may feel multiple effects, such as a headache, dizziness, or fatigue. In addition, you may have a dry mouth and feel very thirsty. In children, the parent should watch for symptoms such as signs of fever, unusual tiredness, or no wet diapers.

Why am I feeling dehydrated?

Several things can cause dehydration, but anytime you or your child experiences excessive loss of bodily fluids through sickness, it can be hard to stay hydrated. You or your kids can lose more water and electrolytes than you’re able to easily replace by eating and drinking.

Bodily functions or disturbances of bodily functions that
can cause you or your kids to lose fluids and electrolytes include:

    You lose water and electrolytes when you sweat, so the more you sweat, the sooner you might become dehydrated.

What are electrolytes?

Electrolytes are minerals essential to your health. They help carry electrical signals that power your nerves and muscles, maintain your blood’s proper pH, and balance fluids in your body. You get electrolytes from what you eat and drink, and you lose them whenever you lose fluids (like when you sweat or go to the bathroom).
