With warmer weather arriving in Bath, we’re seeing more runners, cyclists, hikers, and team sport enthusiasts making the most of the sunshine. Whether you're training for an event or just enjoying movement outdoors, it’s crucial to stay mindful of how heat can impact performance, hydration, and injury risk.
At Hybrid Health, we specialise in helping clients stay strong, pain-free, and resilient—whatever the season. Here are our expert tips to help you exercise safely and effectively during a heatwave.
Should You Exercise in a Heatwave?
The ideal temperature for physical activity typically ranges between 20–22°C. Once it pushes past 30°C, your body begins to work significantly harder—putting stress on your cardiovascular system and increasing the risk of fatigue, dehydration, and heat-related illnesses.
That doesn’t mean you have to stop training entirely. Instead, adjust your expectations.
“Training in the heat naturally feels tougher. It’s important to slow your pace, prioritise recovery, and understand that your body is doing more work under these conditions,” explains the team at Hybrid Health.
Adapt your mindset: embrace the heat as a form of conditioning, and stay attuned to how your body responds.
How Your Body Responds to Exercising in Heat
🔥 Increased Core Temperature
As temperatures rise, your body diverts blood to the skin to help you cool down. This reduces the oxygen available for working muscles, making movement feel harder. When heat isn't dissipated effectively, your internal temperature can climb dangerously high, increasing the risk of heat exhaustion or heat stroke.
Top tip: Cool down gradually post-workout, stay in motion for 10 minutes, and rehydrate immediately.
❤️ Faster Heart Rate
For every 1°C increase in body temperature, your heart beats around 10 beats faster per minute. If you’re monitoring your heart rate for endurance or rehab purposes, consider adjusting your training zones.

Common Heat-Related Illnesses to Watch For
Heat cramps: painful spasms, usually in the legs, after intense activity
Heat exhaustion: dizziness, nausea, excessive sweating, weakness
Heat stroke (medical emergency): confusion, fatigue, and body temperature over 40°C
Prevention is key: Listen to your body, rest often, and don’t push through symptoms.
Stay Hydrated: Your Summer Hydration Plan
Not sweating much? You may already be dehydrated. Adults should aim for:
2–2.5 litres daily, but in hot weather:
Up to 3L for men
2.5L for women
Add electrolytes to your hydration plan—especially during prolonged or intense workouts. Isotonic drinks, coconut water, or electrolyte tablets can help maintain performance and support recovery.
“Over-hydration can be just as dangerous as dehydration. Balance water with sodium, potassium, and magnesium—especially if you’re sweating heavily,” says the Hybrid Health team.
What to Wear: Summer Workout Clothing Tips
Best times to train: early morning or after 6PM when it’s cooler
Wear breathable, loose-fitting, moisture-wicking clothing
Avoid tight Lycra or compression gear that restricts airflow
Consider cooling vests, buffs, or neck towels on very hot days
Don’t forget a good SPF 30+ sunscreen, sunglasses, and a breathable hat if you’re outdoors for long sessions.
Mix It Up: Try Indoor or Lower-Intensity Alternatives
Summer is the perfect time to diversify your fitness routine:
Add indoor strength training or Pilates
Explore mobility work or rehab-focused exercises with a physio
Use this time to correct movement patterns and address any pre-existing injuries or niggles
At Hybrid Health, our team can help tailor a balanced, heat-safe training plan that works for your goals—whether that’s peak performance or injury prevention.
Final Tips: Stay Cool, Stay Consistent
With the right mindset, hydration, and recovery strategy, training in hot weather can help boost your cardiovascular system and endurance. But more importantly, it’s about keeping your body safe and performing at its best.
