Staying out in the sun should feel good—not dangerous. But when the heat turns extreme, your body may struggle to keep up. That’s when a heat-related illness like heatstroke becomes a real risk. It can happen faster than you’d think, especially during summer spikes or when working outdoors.

Here’s your guide to understanding heatstroke, spotting the warning signs, and acting fast when every minute counts.

What Is Heatstroke?

Heatstroke happens when your body’s internal temperature shoots up past 104°F (40°C) and can’t cool down. Your brain, organs, and muscles start overheating. Unlike heat exhaustion—which may just leave you dizzy or tired—heatstroke is dangerous and demands urgent medical help.

It’s more than just feeling hot or flushed. With heatstroke, your body’s cooling system has shut down. It stops sweating. Your internal thermostat breaks. And you lose control.

Recognizing the Early Signs of Heatstroke

When it comes to heatstroke, time is everything. Early recognition can prevent lasting harm.

Look for these signs:

• Body temperature over 104°F (use a thermometer if available)
• Hot, red, and dry skin (a sign of lack of sweating)
• Headache that won’t quit
• Fast, pounding heartbeat
• Nausea or vomiting
• Slurred speech
• Dizziness or fainting
• Confusion or agitation
• Seizures in extreme cases

Even if just a few of these symptoms show up, don’t wait. It’s always better to overreact and be wrong than underreact and risk someone’s life.

Risk Factors That Increase Heatstroke Chances

Anyone can get heatstroke. But some people are more likely to suffer from it than others.

Major risk factors of heatstroke include:

• Age (very young children and older adults are most vulnerable)
• Outdoor workers (construction, agriculture, delivery services)
• Athletes, especially those training in high-heat
• People with heart disease, obesity, or chronic illness
• Taking medications that affect hydration (like diuretics or antihistamines)
• Wearing heavy, tight clothing in the sun

A humid day? That makes it worse. Sweat won’t evaporate properly. Your body holds in more heat.

What to Do During Heatstroke: Immediate Actions

You see someone showing symptoms. Don’t panic. But don’t wait, either. Here’s exactly what to do during heatstroke:

1. Call 911 right away – Don’t try to drive them to a hospital yourself unless emergency help is unavailable.
2. Move to shade or indoors – Get them out of direct sunlight.
3. Remove extra clothing – Loosen or take off outerwear.
4. Cool them down – Use these methods:
   • Apply cold, wet towel or cloth to the neck, armpits, groin, and back
   • Spray or sponge them with cool water
   • Fan them if possible
   • If ice packs are available, use them on high blood-flow areas
5. Hydrate if possible – Only give water if the person is fully conscious and not vomiting.
6. Stay with them until help arrives – Watch for changes in breathing, pulse, or alertness.

Don’t give them salt tablets, caffeine, or alcohol. These can make things worse.

What NOT to Do During Heatstroke

Mistakes can cause more harm than good. Avoid these:

• Don’t force liquids if they’re unconscious
• Don’t wait it out—this isn’t a “sleep it off” condition
• Don’t use ice-cold baths unless advised by professionals (can shock the body)
• Don’t assume sweating means they’re okay—lack of sweating is more dangerous, but some cases still involve sweating

When to Head to the Emergency Room

Tips to Prevent Heatstroke

The best treatment? Avoiding it altogether. These practical tips go a long way:

• Hydrate, hydrate, hydrate – Water is your best defense
• Wear light, breathable clothing – Let your skin breathe
• Avoid midday sun – Try to stay indoors from 11 a.m. to 4 p.m.
• Use sunscreen – Prevent sunburn, which affects temperature control
• Check the forecast – High humidity? Stay in
• Rest often – Especially during outdoor work or play

Let your body cool before it overheats. Don’t push through heat.

How Parents and Caregivers Can Stay Vigilant

Children often can’t tell us when they’re overheating. And older adults may not feel thirst or heat as easily. Keep an eye out.

For kids:

• Always bring water bottles
• Take shade breaks during playtime
• Never leave a child in a parked car—not even for five minutes

For seniors:

• Encourage drinking fluids throughout the day
• Keep fans or AC running
• Check on them twice a day during heat waves

Be their advocate. Be proactive.

Key Takeaway

Heatstroke isn’t rare. It’s not a freak accident. It’s something we can prevent if we stay alert and act fast. Whether you’re out for a summer run or working a shift in the sun, protect yourself and others.

Remember, if you or someone near you shows signs of overheating, and especially a lack of sweating, it’s time to act. Don’t brush it off.
