1. Understand Why Dehydration Happens

Dehydration occurs when your body loses more fluids than it takes in. In summer, heat, humidity, sweat—and sometimes salt intake—combine and accelerate fluid loss. According to the Cleveland Clinic, if you’re already thirsty, you’re mildly dehydrated—so it’s crucial to drink before thirst sets in my.clevelandclinic.org.

Common signs include:

Unchecked, mild dehydration may escalate to heat exhaustion or even heat stroke—a serious medical emergency newsinhealth.nih.gov+15hopkinsmedicine.org+15texashealth.org+15.


2. Drink Smart: How Much & When

Don’t wait for thirst. The University of Iowa Hospitals recommends:

  • Drink before heading outdoors—plan hydration
  • Continue sipping every 15–20 minutes, 6 oz each time—approximately 24–32 oz/hour during heat exposure uabmedicine.org

3. Electrolytes: Why They Matter

When we sweat, we lose not only water but also electrolytes like sodium, potassium, and magnesium. Drinking plain water helps—but during heavy sweating, plain water can dilute electrolytes dangerously. Experts recommend pairing water with sodium-rich snacks or using balanced electrolyte drinks to maintain fluid and mineral levels verywellhealth.com+1thesun.co.uk+1.
