Heat and Dehydration

Heat And Dehydration

Fun in the sun can turn not-so-fun if heat leaves you or your little one dehydrated. Whether your climate is hot year-round or it only hits high temperatures in the summer, heat can lead to perspiration, and perspiration can cause dehydration—which may make you or your little one feel worse. But, besides drinking water, there’s something everyone can do to feel better fast—rehydrate with Pedialyte®.

How heat can lead to dehydration


Dehydration often occurs in hot weather because the hotter you or your little one’s body temperature becomes, the more you perspire or sweat. Sweat is our body’s natural cooling mechanism, but if you sweat a lot, you can lose enough fluids and electrolytes to leave you dehydrated. So if you or your little one is feeling tired, headachy, or experiencing other symptoms of dehydration, rehydrate with Pedialyte to See the Lyte and feel better fast.

Heat Exhaustion


It’s really important to keep yourself and your kids hydrated in the heat because dehydration can contribute to more serious conditions—heat exhaustion or heat strokes.

Common Heat Wave Signs and Symptoms:

  • Rapid pulse
  • Muscle or stomach cramps
  • Excessive sweating
  • Weakness and fatigue
  • Clammy and pale skin
  • Nausea or vomiting
  • Fainting

Make sure to get to a cooler location, rest, and rehydrate if you or your little one start to experience any of these symptoms. Left untreated, heat exhaustion can become heat stroke—a much more serious condition that may require medical attention or hospitalization.
