It’s a July Saturday in Royal Palm Beach. You did a few laps on the trail at Commons Park, then spent the afternoon on yard work. Now your head is pounding, your shirt is soaked, you feel shaky, and the glass of water you just drank isn’t helping. Knowing heat exhaustion signs could be the difference between a rough evening and a trip to the ER. Here’s what to watch for, what to do right away, and how to recover the right way.

The problem: South Florida heat sneaks up on people who live here
Locals tend to think they’re used to the heat. And in a way, they are. But being used to it doesn’t make your body immune to it.
Royal Palm Beach has great reasons to be outside. The Village’s Commons Park has about three miles of paved walking, jogging and bike trails around a 19-acre lake, plus outdoor fitness equipment, according to the Village of Royal Palm Beach. Add youth sports, weekend yard work, outdoor jobs, and summer afternoons at the pool, and you have a lot of people spending a lot of hours in the sun.
Then add humidity. When the air is thick, sweat doesn’t evaporate well. And evaporating sweat is how your body cools itself. So you keep sweating, you keep losing fluid and salt, and you don’t cool down the way you should.
Why “I’ll just push through” is risky
The National Weather Service office in Miami issues a heat advisory for Palm Beach County when the heat index, or “feels like” temperature, is forecast to reach 108°F or higher for at least two hours. You can check the forecast on the NWS Miami heat page.
But heat illness doesn’t wait for an advisory. Plenty of people get sick on ordinary hot days because they:
- Started the day already low on fluids
- Worked or exercised in the hottest hours, roughly late morning to late afternoon
- Drank water but didn’t replace salt after hours of sweating
- Skipped meals
- Had a drink or two the night before
- Take medicines that affect fluid balance or how the body handles heat
Pushing through feels tough. But heat illness can get worse fast, and heat stroke can be deadly.
Heat exhaustion signs to know
MedlinePlus, from the National Library of Medicine, lists the main types of heat illness. Here’s what they look like in plain English.
Heat cramps (the early warning)
- Painful muscle cramps or spasms, often in the legs, arms or belly
- Heavy sweating
Cramps are your body’s early alarm. Stop, cool down and drink.
Heat exhaustion (stop now)
These are the most common heat exhaustion signs:
- Heavy sweating
- Cool, pale, clammy skin
- Feeling dizzy or faint
- Headache
- Nausea or vomiting
- Muscle cramps
- A fast, weak pulse
- Feeling very tired or weak
Heat stroke (call 911)
- Confusion, slurred speech or acting strange
- Fainting or passing out
- Seizures
- Hot skin, which may be dry or still sweaty
- Very high body temperature
If you see signs of heat stroke, call 911 right away. While you wait, move the person to shade or air conditioning and cool them with water, wet towels or ice packs on the neck, armpits and groin. Don’t give fluids to someone who is confused or can’t swallow safely.
What to do for heat exhaustion right away
If you or someone near you shows heat exhaustion signs:
- Stop the activity. Now, not after one more lap.
- Get to shade or air conditioning.
- Loosen or remove extra clothing.
- Cool the skin with a cool shower, wet cloths or a fan.
- Sip cool water or an electrolyte drink if you can keep it down.
- Rest and watch. You should start feeling better within about an hour.
Get medical help if symptoms get worse, last more than an hour, you keep vomiting, or you can’t keep fluids down. And if confusion or fainting shows up, that’s heat stroke territory. Call 911.
Who should be extra careful
Some people get sick from heat faster than others:
- Adults over 65, because thirst signals weaken with age
- Young kids, who heat up faster
- Outdoor workers, like landscapers, roofers and barn staff
- People with heart, kidney or lung problems
- People on certain medicines, like water pills, some blood pressure medicines, and some mental health medicines
- People on GLP-1 weight-loss medicines, which can lower thirst along with appetite
- Anyone who’s been sick with vomiting or diarrhea in the last few days
If that’s you, plan your outdoor time for early morning or evening, and keep fluids with you.
How to prevent heat exhaustion on Royal Palm Beach summer days
- Go early or go late. Walk the trail at sunrise or after the sun drops, not at 2 p.m.
- Drink before you’re thirsty. Start the day with a full glass of water.
- Replace salt on long, sweaty days. An electrolyte drink or salty snack helps.
- Dress light. Loose, light-colored clothing and a hat.
- Take shade breaks. Every 20 to 30 minutes in strong heat.
- Check your urine. Pale yellow means you’re on track.
- Use the buddy system. Watch each other for early signs.
- Skip alcohol before outdoor work. It dries you out.
The day after: why you may still feel off
Even after you cool down, heat exhaustion can leave you feeling tired, achy and foggy the next day. That’s common. Your body lost a lot of fluid and salt, and it worked hard to cool itself.
Take the next day easy:
- Keep sipping fluids through the day, not all at once
- Eat regular meals with some salt, like soup, crackers or a sandwich
- Skip hard workouts and long sun exposure for a day or two
- Sleep in a cool room if you can
- Watch your urine color
If you feel worse instead of better the next day, or you notice confusion, chest pain, or very little urine, get checked by a doctor.
Recovery: when water isn’t catching you up
Most people recover from mild heat exhaustion with rest, cooling, fluids and food. But some people feel drained for a day or two, especially if they also lost fluids from vomiting.
That’s when some patients ask about IV fluids. Here’s how it works at a physician-led practice:
- Emergencies come first. IV therapy at our office is not a substitute for urgent or emergency care.
- Screening comes next. A clinician checks your history, medicines and vital signs, and asks what happened.
- Then a decision. If it fits, our IV drip menu includes a Hydration Drip with fluids and electrolytes. If it doesn’t fit, or if your symptoms point to something more serious, we’ll tell you where to go instead.
IV fluids aren’t right for everyone. Heart and kidney problems, pregnancy and some medicines can change the answer. Our IV therapy safety FAQ explains who should wait.
Hydration IV in Greenacres: coming in from Royal Palm Beach
Our office is in Greenacres, not Royal Palm Beach, and IV therapy happens only at our office. Many Royal Palm Beach patients head south on State Road 7, then east on Forest Hill Boulevard or Lake Worth Road to reach us at 5315 Lake Worth Road. For most, a hydration IV Greenacres visit is a shorter drive than they expected. If you’re still feeling the heat, have someone else drive.
Why a physician-led visit matters
Heat illness is a medical issue. You deserve a medical answer, not a menu. At our physician-led IV therapy program, every visit starts with a real screening and an honest call, including “you don’t need an IV” or “you need a different level of care.”
