The Pros Don’t Push Through: How to Stay Active Safely When the Heat Rises

When conditions get hard, most of us think we have two choices: quit or push through. We treat toughness as the willingness to grit our teeth and power ahead, no matter what our body is telling us. But there’s a third option — the one the pros use — and it’s often overlooked.

That was my biggest takeaway from a recent episode of The Educated Patient Podcast, when I sat down with Maria Kyriacou, M.D., a primary care sports medicine physician at Baptist Health Orthopedic Care. As the team physician for the Miami Dolphins, the Florida Panthers and Inter Miami, Kyriacou knows how elite athletes stay safe while performing in brutal heat.

And here’s what surprised me most: The people paid to push their bodies to the limit opt for adaptation instead of pushing through.

The Pros Don’t Wing It

Kyriacou explained that heat acclimation is a structured, progressive process that athletes shouldn’t skip. New players arriving from cooler climates get extra attention during training camp. Rather than throwing anyone into full-intensity heat on Day 1, teams gradually increase how long players train, how much gear they wear and how hard they push over the course of days.

Think about that. These are professional athletes; even they earn their way into the heat step by step. The intensity is built, not assumed.

This brings up a lesson beyond sports. We tend to admire the all-at-once approach: the crash diet, the sudden overhaul, the “I’ll just power through.” But the smartest performers in the world build capacity in layers. Adaptation is not a sign of weakness.

What This Means for the Rest of Us

The same principles apply to everyday exercisers, Kyriacou said, whether you’re visiting Florida from a cooler state or you’ve lived here for years. Instead of pushing through discomfort, she recommends adjusting one of three levers: intensity, duration or the time of day you exercise.

The reason is physiological. Once your core temperature rises, she explained, your body redirects blood circulation toward the skin to support sweating and cooling. That pulls resources away from your working muscles, which is exactly why you fatigue faster in the heat. It isn’t that you’re out of shape that day. Your body is doing exactly what it’s designed to do, and fighting it head-on is a losing battle.

Know Your Own Limits

This is where the advice gets personal. For people with impaired heart function or those taking medications like diuretics or stimulants, heat and humidity force the heart to work harder. Some medications can impair the body’s ability to sweat or regulate fluids.

Kyriacou’s guidance is to exercise in the cooler bookends of the day, early morning or later evening, and to talk with your physician about your individualized limits. That’s especially true around sodium and fluid intake for anyone managing a condition like heart failure. The goal is clarity about your body and your situation.

Fuel and Hydrate With Intention

When it comes to hydration, Kyriacou offered refreshingly specific targets:

1. Before: Drink 16 to 20 ounces of water 45 to 60 minutes before your workout.
2. During: For sessions longer than an hour, add 4 to 6 ounces of water roughly every 20 minutes, along with electrolytes.
3. Electrolytes: Rather than relying only on packaged products, which can be high in sodium, reach for whole foods — a banana with almonds, or water-rich options like watermelon, cucumber and bell peppers.
4. Bookend your workout: Warm up for five to 10 minutes beforehand and cool down afterward with something light like a turkey wrap, yogurt or a smoothie.

Learn to Read the Warning Signs

One distinction Kyriacou drew is worth memorizing. Ordinary muscle fatigue builds gradually. Heat illness tends to appear suddenly. Warning signs that call for immediate medical attention include confusion, dizziness, headache, vomiting or collapsing. If those show up fast, that’s your body raising an alarm. You should not take these signs as an invitation to tough it out.

The Smart-Heat Playbook

If you take one framework into the warm months, make it this:

• Acclimate gradually. Ease into the heat over days, not all at once, just like the pros.
• Adjust a lever. Change intensity, duration or timing before you resort to grinding through.
• Hydrate on a schedule. Front-load water, top off during long sessions, and lean on whole foods for electrolytes.
• Know your personal limits. Heart condition or certain medications? Get individualized guidance from your doctor.
• Respect sudden symptoms. Gradual fatigue is normal; sudden confusion, dizziness or nausea is not.

What I appreciated most was Kyriacou’s closing message: The heat is not a reason to stop moving. “Once you stop working out,” she noted, “the muscles can begin to atrophy.” The point was never to retreat indoors until fall. It’s to build in the right adaptations so you can keep going safely.

That’s the quiet freedom hiding in all of this. Staying active is about being wise enough to work with your body. Do that, and the heat stops being something you survive and starts being just another condition you’ve learned to move through.
