Hydration is key to beating the heat in Florida

Jul 1, 2025 By FLORIDA GOVERNMENTAL UTILITY AUTHORITY 3 min read

The heat is on throughout the Sunshine State. While July is typically the hottest month of the year, June proved to be a rapid preheat to the hot and humid days that will last through August and often beyond.

While hydration is important year-round, it’s especially critical during the summer months when residents and tourists alike are “soaking up the sun” at the beach and many other outdoor activities.

Founded in 2016 in honor of a football coach committed to the health, safety and success of his players, National Hydration Day on June 23 reminded us of the importance of continuously replenishing this life-giving liquid that is lost through sweating, going to the bathroom and even just breathing.

– What are the benefits of drinking water?

According to the National Institutes of Health (NIH), about two-thirds of our body weight is comprised of water. All human cells need water to work; it’s the base for every single type of bodily fluid. The Centers for Disease Control (CDC) notes that water helps you keep a normal temperature, lubricate and cushion joints, protect your spinal cord and get rid of wastes.

– What is dehydration?

According to the Cleveland Clinic, dehydration is the absence of enough water in your body. When you don’t drink enough water, you become dehydrated. When you lose more fluid than you are taking in, your body can’t function normally. Those drinks account for about 80% of our daily intake of fluid, while the remainder comes from food, according to the Mayo Clinic.

– What are some signs of dehydration?

One of the earliest signs of dehydration might not be what you think. We tend to think of “being thirsty” as a sign to drink something so we don’t get dehydrated, but it’s actually an initial sign that you are already dehydrated. Other signs may include headache, fatigue, dry mouth, flushed skin, swollen feet and dizziness. Dehydration is more likely on a particularly hot day if you sweat a lot, or if you’re sick with fever, diarrhea or vomiting.

– How is dehydration harmful?

In addition to bodily functions being compromised and the discomforts associated with the symptoms of dehydration, the CDC says dehydration can cause unclear thinking, mood change, overheating, constipation and kidney stones. If ignored, it can contribute to life-threatening illnesses like heatstroke.

– What should I do if I am dehydrated?

Responding to dehydration depends on the level of severity. The Cleveland Clinic says that healthcare providers typically put dehydration into three categories: mild, moderate and severe. A mild case usually requires simply taking in more fluids by mouth, possible with a drink that contains electrolytes if there is significant sweating or fluid loss from sickness. Moderate and severe cases may require a visit to an urgent care facility, emergency room or hospital. When in doubt, call 911.

– How can I prevent dehydration?

The CDC offers these tips to stay hydrated:

Carry a reusable water bottle with you at all times and take advantage of a growing number of public refill stations to keep it topped off.

Freeze water in freezer-safe bottles to keep your water ice-cold throughout the day.

Choose water over sugary drinks; it’s healthier and you’ll eliminate calories.

Opt for water over sodas and other beverages when eating out; you’ll feel healthier and save money.

Serve water during meals at home; add a wedge of lemon or lime for some fresh flavor.
