Article: Spotting heat exhaustion: what lifeguards should recognize

Let’s talk about those scorchers at the pool or beach—the days when the sun feels like a heat lamp and every breath seems a tad heavier. Heat exhaustion isn’t rare, and it isn’t random. It’s a signal that the body is overheating and struggling to cool itself. For lifeguards, recognizing the right signs isn’t just about ticking a box on a checklist. It’s about reading a person’s body in real time and acting fast to stop a situation from getting worse.

Here’s the thing about heat-related trouble: the body loses water and electrolytes through sweat. When that happens, blood volume drops, blood pressure can fall, and the brain doesn’t get the same steady flow of blood it needs. The result? A person can start feeling unsteady, woozy, or simply not like themselves. That’s heat exhaustion, and the telltale signal to watch for is heavy sweating paired with dizziness.

The standout indicator you should memorize is straightforward: heavy sweating plus dizziness. If someone is drenched in sweat and reports feeling lightheaded or faint, that’s your cue to jump into action. It’s not about guessing or hoping it’s nothing. Heat exhaustion is a real, treatable condition—but it needs attention before it can escalate to something more dangerous, like heat stroke.

Now, let’s separate the signal from the noise. Why not fever or cold skin? Fever above 100°F isn’t a typical marker of heat exhaustion. Fever usually suggests an infection or another medical issue, not overheating from the sun and exertion. Cold or pale skin can actually point toward heat stroke or shock, which is a different, more critical scenario requiring urgent care. And rapid weight gain isn’t a sign you can pin on heat exhaustion; weight fluctuations can come from many factors, but they don’t reliably pinpoint heat-related stress.

So, why does this matter for lifeguards? Because on a hot day, a quick, accurate read can prevent a more serious outcome. When a patron shows heavy sweating and dizziness, you’re not just noting a symptom—you’re initiating a planned response that keeps them safe and stable.

What a smart lifeguard does in response

Let me explain the flow you’ll want to follow, step by step, in real-world terms.

• Move to a cooler spot and remove excess clothing. Get the person out of direct sun and into shade or a cooler environment as soon as possible. If you’re on a patrol with a shade tent or a cooling station, guide them there.

• Check responsiveness and airway. If they’re conscious, ask simple questions: How do you feel? Can you speak clearly? Have they had water recently? If they’re not fully alert, start standard first aid procedures and call for help immediately.

• Hydration and cooling. Offer small sips of water or an electrolyte drink if they’re able to drink without danger of choking. Use a cool compress or a damp, cool cloth on the neck, armpits, and wrists to help the body shed heat. A fan nearby can speed up the cooling process.

• Monitor vital signs. Keep an eye on their mental status, sweating, skin temperature, and any changes in balance. If symptoms improve after cooling and fluids, that’s a good sign, but keep monitoring for changes for a while.

• Call for medical backup if needed. If the person does not improve within 10-15 minutes, or if dizziness worsens, or if fever, confusion, vomiting, or fainting appears, don’t hesitate to bring in EMS. Heat exhaustion can evolve; quicker escalation saves lives.

• Document and review. After the person is safe, jot down what happened, what you observed, and what steps you took. This isn’t about blame; it’s about learning and improving how you handle future incidents.

A few practical tips that help with everyday heat risk

Heat can be sneaky. It’s not only the peak sun hours; it’s the combination of exertion, hydration, and clothing. Here are some practical moves that can cut risk and keep people feeling okay longer.

• Hydration is not optional. Encourage regular sips of water or electrolyte drinks, especially for athletes or kids who are active in the sun. A good rule of thumb: if you’re thirsty, you’re already a step behind.

• Shade matters. Portable shade structures aren’t just a nicety—they’re a lifesaver on hot days. Encourage breaks in shade every so often, even for strong swimmers.

• Pace and rest. When crowds surge, it’s easy to push people to stay in the water longer. Remind patrons that rest periods are part of staying safe. Short, regular breaks help bodies reset and prevent overheating.

• Gear matters. Sun hats, sunglasses, and sunscreen aren’t just for comfort; they’re moisture retention helpers for the day. Lightweight, breathable fabrics inside and out help too.

• Watch the signs, not just the clock. People can overheat quickly, especially kids, older adults, or those who are already dehydrated. Check for dizziness, clammy skin, or a wobbly walk—these aren’t “soft cues”—they’re your early warning signals.

• Don’t mix with alcohol or heavy meals. Intense heat plus heavy meals or alcohol can mask symptoms or slow recovery, which makes your job harder later on.

A few relatable cues and a quick mental checklist

Think of heat exhaustion as a small alarm bell before the siren. If you hear a patron say they feel faint, see heavy sweating, and notice dizziness, that’s your moment to intervene. You don’t need a medical degree to act—just the awareness and the right steps.

• Start with the basics: shade, water, cooling. If there’s no improvement after a short window, escalate.

• Keep the vibe calm. People in distress often panic; your steady, clear instructions help them stay focused and keep breathing normally.

• Use your tools. A cooling towel, a reusable water bottle, a portable fan, even a phone to call for backup—these are all part of your toolkit.

• Remember where you are in the day. Peak heat isn’t only about temperature; it’s about duration and activity. A long afternoon of sun plus physical exertion can catch up with anyone.

A quick analogy to keep in mind

Think of the body as a car running in heat. Sweat is like the radiator’s coolant, keeping the engine from overheating. If you lose too much coolant and the engine starts misfiring (that’s dizziness and faintness), you pull over, give it a rest, and hydrate it back up. If you ignore the warning lights and push on, you risk a catastrophic failure. Lifeguards aren’t just lifters of people from the water; we’re caretakers of that engine on hot days.

Common misconceptions, cleared up

• Fever is not the flag for heat exhaustion. A fever points to something else going on inside the body.

• Cold skin isn’t a sign of heat exhaustion. It can indicate someone is in trouble and might be shifting toward heat stroke or shock.

• Rapid weight gain isn’t a hallmark of heat exhaustion. Weight shifts come from fluids and other factors but aren’t reliable indicators in this context.

The bottom line

Heavy sweating and dizziness are the hallmark clues lifeguards use to identify heat exhaustion. When you see that combination, act fast: remove the person from the sun, help them cool down, rehydrate, monitor, and call for help if they don’t improve promptly. It’s a simple, effective sequence that can prevent a bad turn and keep the pool—your place of service and safety—a calm, welcoming space even on the hottest days.

If you’re working near water, you know how quickly a day can change. One moment you’re counting laps; the next, you’re standing between someone’s discomfort and a healthier, safer recovery. Then again, that’s the job—a blend of attentiveness, quick judgment, and a touch of everyday empathy. You’ve got this.

Final takeaway: heavy sweating plus dizziness is the key signal. All the rest—fever, cold skin, weight shifts—tells a different story. Stay alert, stay cool, and be ready to act. Your training, instincts, and care can make all the difference when summer heat spikes at the pool.
