In summer, temperatures in Spain can vary considerably depending on the region. In the south and along the Mediterranean coast, the heat and humidity can be intense, while the north can enjoy cooler temperatures. This means that recommendations for outdoor running aren't the same for everyone. How do we know when it's too hot to train outdoors?
It's clear that avoiding the hottest hours of the day is crucial. However, experts say there's no problem with going for a run in the late afternoon, even when the temperature is 30-35°C . In fact, it's common to participate in night races, like the Guadalquivir race, where temperatures at 22:00 PM can reach 40°C with the added body heat of the runners.
Provided precautions are taken, good hydration is maintained , and physical exertion is taken into account , there are generally no problems when training in extreme heat conditions.
Preparing the body for high temperatures
Not everyone can run in temperatures above 30°C, not even professional athletes . High temperatures cause dehydration due to excessive sweating , and can also lead to muscle cramps or a general feeling of fatigue. It's important to be mindful of your own effort and not push yourself too hard; it's normal for performance to decrease during the hot months, and this shouldn't be a cause for concern.
Pushing your pace while running in hot conditions can lead to serious complications, such as fainting or heatstroke. According to experts, the ideal approach is to gradually acclimate your body to high temperatures over 14 days . The body needs time to adapt to new stimuli, so the necessary conditions must be in place for this adaptation to occur.
The amount of sweat can vary between one and four liters
Sweating is a natural way to regulate body temperature . During physical exercise in hot conditions, you can lose between one and four liters of fluids, as well as essential salts and minerals .
Such significant fluid loss should never occur. Dehydration not only compromises performance but also impairs blood circulation and can lead to serious complications. Below, we offer a series of suggestions and tips for coping with the heat while running, along with information from competitor sources that reinforce our guidelines.
Adaptations for running in the heat
1. Take a sweat test
- A sweat test is useful for determining how much fluid you should drink. First, weigh yourself before running and then after running for about 40 minutes in the same hot conditions.
- Weight loss in grams translates directly into milliliters of water to be replaced during the next workout.
- It is essential not to forget the electrolytes, especially sodium, since the loss of this mineral can lead to a decrease in performance.
2. The importance of acclimatization
Heat acclimatization is not just about adapting to high temperatures, but also about learning to manage hydration and environmental conditions. A researcher from Brock University points out that training in warm conditions increases physiological adaptation to heat. The three phases include:
- Short-term exposure (less than 7 days).
- Medium-term exposure (between 8 and 14 days).
- Long-term exposure (more than 14 days).
3. Wear appropriate clothing
Clothing is another critical aspect when running in the heat. Opting for loose , breathable shirts helps improve airflow. It's advisable to avoid cotton, as it tends to retain moisture, and prioritize technical fabrics that allow for quick drying.
4. Constant hydration
Staying properly hydrated is crucial for surviving in the heat. During summer training phases, consider incorporating electrolyte drinks to replenish what you lose through sweat.
5. Take care of your health and well-being
Preventing health problems caused by dehydration and heat should be a priority. Avoiding overtraining, staying active during cooler hours, and listening to your body are fundamental principles.
When running in summer becomes complicated
In addition to the adjustments you need to make to your routines, there are some important points to consider:
- Avoid rush hours: It is best to run in the morning or in the evening, since the temperatures are more bearable at those times. You can find more information about the best time to exercise in summer in this article.
- Route planning: Choose shaded paths, preferably in parks or forest areas, where the air is fresher and there is less risk of dehydration.
- Listen to your body: If you experience dizziness, cramps, or any unusual symptoms, find a cool place and rest before continuing.
- Use accessories: Hats, sunglasses, and sweatbands are essential for protecting yourself from solar radiation and improving comfort during exercise.
Additional tips for running in summer
1. Watch your diet
Nutrition plays a crucial role in athletic performance, especially during the warmer months. Increase your consumption of fruits and vegetables rich in water, vitamins, and minerals.
2. Stretching and warming up
Before running, taking the time for a proper warm-up and stretching routine can prevent injuries and improve muscle flexibility , as muscles are more prone to injury in the heat. Consider incorporating specific summer stretching routines before heading out for a run.
3. Enjoy running
Remember that running should be an enjoyable activity , so adjusting your expectations and enjoying the process is key to staying motivated. For those who enjoy running on the beach, you can explore the benefits this offers.
Running in the summer doesn't have to be complicated if you follow these recommendations. Adapting your training to the weather, taking care of your body, and maintaining a balanced approach are the keys to enjoying this healthy activity even in the hottest months. Go for a run and enjoy the outdoors!
