Florida’s year-round balmy weather creates the perfect environment for outdoor activities, but it also increases the risk of dehydration. Whether you are swimming at Clearwater Beach, trimming palm trees in your backyard, kayaking in a crystal-clear spring, or simply basking in the sunshine, staying hydrated is essential to maintaining your overall health and well-being. At South Tampa Immediate Care, we regularly treat patients experiencing symptoms of dehydration and heat-related illnesses, especially during the sweltering summer months. Fortunately, dehydration can often be prevented by taking a few simple precautions.
What Is Dehydration?
Water is a vital nutrient that makes up approximately 60% of the human body. Fluid is mainly lost through urination, as the kidneys filter excess water and waste from the blood. Additionally, when the body begins to overheat, it regulates its internal temperature naturally by releasing moisture from sweat glands in the skin. As the sweat evaporates from the skin’s surface, it helps cool the body down.
In perpetually muggy Florida, sweating is common, especially during physical activities and prolonged sun exposure. However, because the humid outdoor air is already saturated with water vapor, it can’t hold much more. This makes it harder for sweat to evaporate from the skin and cool the body, leading to even more sweating.
When bodily fluids are not replenished quickly enough, the body may begin to lose more water than it takes in. Known as dehydration, the resulting imbalance can affect several key bodily systems, including the circulatory, urinary, digestive, nervous, and muscular systems. It can also reduce blood volume and pressure, strain kidney function, slow digestion, and impair brain performance. While mild dehydration can usually be resolved by drinking water and other fluids right away, more severe cases may require medical attention.
What Are the Symptoms of Dehydration?
Recognizing the warning signs of dehydration can help prevent serious complications, such as kidney problems and low blood volume. Symptoms can vary by age and severity but generally include:
- Dry lips, mouth, and tongue
- Excessive thirst
- Fatigue, weakness, and lethargy
- Flushed (reddened) skin
- Headache
- Heat intolerance or chills
- Infrequent urination or dark-colored urine (healthy urine is clear or pale yellow)
- Lightheadedness
- Muscle cramps
In infants and young children, additional signs of dehydration include listlessness, sunken eyes and cheeks, and tear-free crying. In older adults, dehydration can set in quickly due to decreased thirst sensation.
What Are the Risk Factors for Dehydration?
While anyone can become dehydrated—especially in warm and sultry Florida—certain people are particularly susceptible, including:
- Infants and young children
- Older adults
- Individuals with a chronic health condition, such as diabetes, kidney disease, or heart failure
- People who exercise or work outdoors
- Athletes and others who participate in endurance sports
- Individuals who take medications that increase fluid loss, such as diuretics, laxatives, and certain blood pressure and diabetes drugs
How to Prevent Dehydration
Dehydration prevention begins with staying ahead of the body’s fluid needs. Potentially effective strategies include:
- Drinking fluids continually – Stay well hydrated by sipping water throughout the day, whether you feel thirsty or not.
- Limiting consumption of caffeinated and alcoholic beverages – Caffeine and alcohol are diuretics that promote fluid loss and can contribute to dehydration.
- Eating hydrating foods – Incorporate lots of fruits and vegetables with high water content into your diet. Great choices include cucumbers, lettuce, celery, tomatoes, zucchini, bell peppers, spinach, watermelon, strawberries, cantaloupe, and oranges.
- Dressing appropriately outdoors – Wear lightweight, light-colored, breathable clothing to help reduce sweating.
- Taking breaks from the heat – When spending time outdoors, especially during peak heat hours, take frequent breaks in shaded or air-conditioned spaces.
- Using rehydration drinks when needed – During prolonged physical activity, drinking electrolyte beverages can help replace lost sodium and potassium.
When to Seek Medical Attention for Dehydration
Mild dehydration can often be managed at home or with the assistance of an urgent care provider, who can assess the severity of the condition and recommend appropriate treatment, such as oral rehydration to quickly restore fluid balance. However, severe dehydration requires professional medical attention. It is important to go directly to the nearest hospital emergency room if dehydration symptoms include:
- Dizziness when standing
- Extreme weakness
- Fainting
- Inability to keep fluids down due to vomiting
- Mental confusion or disorientation
- Panting
- Rapid heart rate
- Seizures
