Causes of Dehydration

Dehydration occurs when you don’t drink enough water to support your body's needs. Without treatment, dehydration can be fatal. However, in most cases, mild dehydration causes slight discomfort including symptoms like headaches and feeling light headed. These symptoms occur because without proper hydration and electrolytes, your brain can shrink or contract which can put pressure on the skull. It is important to manage your daily hydration levels to prevent symptoms of dehydration and always hydrate effectively when working out hard or spending a lot of time in the sun because sweating can deplete your body's water faster.

Common Symptoms of Dehydration

Our bodies often signal that we need to replenish our bodies with water. While symptoms can look different from person to person depending on how severely dehydrated they are, common symptoms of dehydration include:

  • Headaches
  • Dizziness
  • Blurry vision
  • Fatigue
  • Dry mouth or lips
  • Craving water

Tips for Preventing and Treating Cases of Dehydration

If you’re experiencing symptoms of dehydration, it is important to listen to your body and rehydrate. If you know that you will be sweating a lot or have a hard workout coming up, taking preventative measures like a pre-workout electrolyte drink and carrying water during your workout is essential to ensure you don’t sweat out all of your water supply. Dehydration is preventable if you take the proper steps to stay hydrated according to your body's needs and activity level. However, if you’re experiencing severe symptoms of dehydration, you should seek medical care for treatment and IV rehydration.
