Summer provides an ideal environment for adventure and endurance sports, with extended daylight and favourable weather conditions. However, the combination of increased physical activity and higher temperatures poses specific physiological challenges. Here, we present eight scientifically grounded tips to help you maintain optimal health and performance throughout the summer months…

1) Maintain Hydration

Thermoregulation is critical in hot weather. Dehydration can impair cognitive function and physical performance, and increase the risk of heat-related illnesses. Consume fluids regularly, aiming for a balanced intake of water and electrolytes to replace sodium, potassium, and other minerals lost through sweat. Research suggests drinking 500 ml of water 2-3 hours before exercise and 200-300 ml every 20 minutes during exercise.

2) Implement Sun Protection Strategies

Prolonged UV exposure can lead to skin damage and increase the risk of skin cancer. Apply broad-spectrum sunscreen with an SPF of at least 30, reapplying every two hours or more frequently if sweating heavily. UV-protective clothing, hats, and sunglasses should be part of your gear to reduce UV exposure.

3) Optimise Nutritional Intake

Nutritional demands increase with higher physical exertion and temperature. Emphasise the intake of antioxidants, vitamins, and minerals from fruits and vegetables to combat oxidative stress. Lean proteins and complex carbohydrates provide sustained energy and aid in muscle repair. Consider consuming smaller, more frequent meals to maintain energy levels and gastrointestinal comfort.

4) Adjust Training Schedule

The body’s ability to dissipate heat is reduced during peak temperatures. Schedule training sessions during the early morning or late evening when ambient temperatures are lower. This aligns with circadian rhythms, which can optimise physiological responses to exercise.

5) Monitor Physiological Signals

Be vigilant for signs of heat-related stress, such as hyperthermia, dehydration, and heat exhaustion. These conditions can manifest as dizziness, nausea, tachycardia, and excessive sweating. Employ tools like wearable monitors to track heart rate and core temperature, adjusting activity intensity based on real-time data.

6) Utilise Appropriate Equipment

Technological advancements in athletic gear can significantly enhance comfort and performance. Select clothing made of moisture-wicking, breathable fabrics to facilitate sweat evaporation and thermal regulation. Hydration packs allow for hands-free hydration, crucial during prolonged activities.

7) Emphasise Recovery Protocols

The physiological strain from heat necessitates enhanced recovery efforts. Post-exercise cooling strategies such as cold water immersion and cryotherapy can reduce core body temperature and inflammation. Incorporate active recovery techniques like foam rolling and stretching to maintain muscle elasticity and joint flexibility.

8) Prioritise Rest & Adaptation

Integrate rest days into your training regimen to allow for physiological recovery and adaptation. Adequate rest supports immune function, reduces the risk of overtraining syndrome, and improves overall performance. Utilise rest days for low-impact activities and mental relaxation to facilitate holistic recovery.

In summary, optimising health and performance in summer requires a multifaceted approach grounded in scientific principles. By maintaining proper hydration, implementing sun protection, optimising nutritional intake, adjusting training schedules, monitoring physiological signals, utilising appropriate equipment, emphasising recovery protocols, and prioritising rest, adventure and endurance athletes can mitigate the challenges of summer conditions and enhance their athletic performance. Stay informed, stay prepared, and make the most of your summer training!
