Dehydration is caused by a lack of fluids in the body. Hot weather and strenuous activity, such as sports, are risk factors for dehydration. It's important to remain hydrated in the summer, especially children who are not aware of the consequences of overheating and may ignore symptoms, such as excessive thirst, altered urination patterns, and dry eyes.
Symptoms are treated by drinking small amounts of water or electrolyte drinks at a time, slowly replacing the fluids in the body to avoid more severe dehydration and its complications, such as heat stroke. Dehydration symptoms can be prevented by drinking plenty of clear fluids throughout the day, but sugary drinks should be avoided, including most sports drinks.
