Dehydration and heat-related illnesses, such as heat exhaustion, pose significant risks during hot weather. Those engaging in outdoor activities, athletes, and individuals exposed to prolonged heat are particularly vulnerable. Symptoms of dehydration include fatigue, headaches, and dizziness, which can escalate to more severe conditions if not addressed. Products like electrolyte packets and cooling towels can mitigate these risks by maintaining hydration and regulating body temperature. However, it’s essential to avoid alcohol, as it can exacerbate dehydration.
