Summer is the perfect time to get outside, be active and soak up some sun. Longer days and warmer weather means everything from early morning runs to weekend hikes, beach volleyball and neighborhood bike rides. But with rising temperatures and humidity, you need to prioritize safety during your summer workouts and outdoor activities.
Whether you’re training for a race, playing outdoor sports or just trying to stay fit, extreme heat can be a real risk for dehydration, heat exhaustion or heat stroke. The good news is you don’t have to stop being active – you just have to be smart about it.
In this guide you’ll find practical, proven tips to help you stay safe, cool and energized while being active in the summer heat.
1. Time Your Workouts Wisely
One of the most important ways to stay safe in the summer heat is to choose the right time of day to be active.
- Early morning is usually the coolest part of the day and best for outdoor exercise.
- Late evening can also work well as the sun goes down, but make sure there’s still enough light and visibility.
- Avoid midday hours, usually between 10am and 4pm when temperatures and UV exposure peak.
If your schedule only allows for midday activity, try to do it indoors or under shade whenever possible.
2. Stay Hydrated—Before, During and After
Sweating more in the heat means your body loses more fluids and electrolytes so hydration is key.
- Drink water throughout the day, not just during exercise.
- For workouts over 60 minutes consider sports drinks with electrolytes to replenish sodium, potassium and magnesium.
- Avoid caffeine and alcohol before workouts as both can dehydrate you.
- A good rule of thumb: if you’re not urinating regularly or your urine is dark yellow, you’re probably dehydrated.
Carry a refillable water bottle with you and take small sips every 15-20 minutes during activity.
3. Dress the Part
Dressing for the heat can make a big difference in how your body regulates temperature.
- Choose lightweight, breathable fabrics like cotton or moisture-wicking materials.
- Light colored clothing reflects the sun, while dark colors absorb heat.* A wide-brimmed hat and UV-blocking sunglasses can help.
- Avoid heavy gear or layers, which trap heat and sweat.
Also apply sweat-resistant sunscreen with at least SPF 30 before going outside – even on cloudy days.
4. Listen to Your Body’s Warning Signs
You need to recognize when your body needs a break or can’t handle the heat.
Signs of heat exhaustion:
- Excessive sweating
- Dizziness or lightheadedness
- Headache
- Nausea
- Muscle cramps
- Weakness or fatigue
Heat stroke is more severe and includes:
- No longer sweating
- Hot, dry skin
- Rapid pulse
- Confusion
- Loss of consciousness
If you or someone around you shows signs of heat exhaustion, stop immediately, move to a cooler place and hydrate. For signs of heat stroke call emergency services – it can be life threatening.
5. Take It Indoors When Needed
There’s no shame in moving your activity inside when it gets too hot. In fact it’s often the smart choice.
Try:
- Home workout videos or virtual fitness classes
- Strength training with dumbbells, resistance bands or bodyweight exercises
- Indoor swimming or aquatic fitness at a local gym or community center
- Yoga or pilates to stay flexible and strong
If you still want some cardio, indoor treadmills, stationary bikes or elliptical machines can keep you moving without the sun.
6. Modify Your Intensity
Summer isn’t always the best time to go for a personal record. It’s okay to scale back the intensity and duration of your workouts.
- Try interval training with rest periods in between.
- Shorten your workouts to 20-30 minutes on really hot days.
- Focus on consistency over intensity to maintain fitness without overheating.
Even a brisk walk or gentle swim can be majorly beneficial without putting stress on your body.
7. Use Cooling Techniques
To help your body cool down naturally, incorporate cooling strategies before, during and after activity.
- Start with a cold shower or splash water on your face before heading outside.
- Carry a cold, damp towel or cooling cloth with you.* Portable fans or misters if you’re in one place.
- Cool down slowly and drink something cold after activity.
You can even freeze your water bottle overnight—it’ll melt slowly and keep your drink cooler longer.
8. Choose Shaded Routes and Locations
When exercising outside, pick shaded areas like parks, trails or tree-lined streets. Not only does shade reduce direct sunlight, but also the ground-level temperature.
Avoid running or biking on hot pavement or concrete which reflects and amplifies heat. Trails with grass or dirt paths are usually cooler.
9. Check the Weather and Air Quality
Before heading out, check the local weather forecast and air quality index.
- High humidity makes it harder for sweat to evaporate, reducing your body’s cooling ability.
- Poor air quality from smog, wildfires or ozone alerts can make outdoor exercise risky, especially for those with asthma or respiratory issues.
If the forecast looks bad, reschedule or move your workout indoors.
10. Buddy System
Whenever possible work out with a friend, especially if you’re doing something intense or off the beaten path. A buddy can help you monitor for heat related issues, stay motivated and stay safe.
If you’re solo, let someone know where you’re going and when you expect to return. Bring a fully charged phone just in case.
Conclusion
Summer is a great time to be active, enjoy nature and longer days—but it comes with challenges. By following these tips you can stay fit, healthy and energized while protecting yourself from heat related risks.
Remember, smart planning, hydration and awareness go a long way. Don’t let the heat hold you back—just be prepared for it.
