High temperatures and physical activity, how to exercise without risking your

The continued rise in global temperatures, linked to climate change and phenomena such as El Niño, is bringing new challenges to human health. Scientists warn that extreme heat can affect not only daily well-being but also physical activity levels, with long-term consequences for public health.

According to experts, physical exercise in high temperatures becomes more difficult and in some cases even dangerous. Activities such as running, walking or cycling in the heat increase the risk of fatigue, dehydration and, in extreme situations, heat stroke.

Researchers explain that during physical activity, the body produces heat and tries to remove it through sweating and increased blood flow to the skin. However, this creates an additional burden on the body, as the same blood is also needed to supply the muscles with oxygen. As a result, fatigue and stress on the heart increase.

A recent study warns that reduced physical activity due to high temperatures could have serious consequences. According to predictions, by 2050 this could be linked to 470,000 to 700,000 premature deaths per year worldwide.

To maintain physical activity even during hot days, experts recommend:

Exercising during the cooler hours of the day, early in the morning or evening;
Avoiding direct exposure to the sun and choosing shaded areas, where temperatures can be 12-15 degrees Celsius lower;
Taking into account humidity and wind, as high humidity reduces the effectiveness of sweating and increases thermal stress;
Reducing the intensity and duration of exercise, as well as taking frequent breaks during activity;
Cooling the body during breaks with cold water, fans or air-conditioned environments;
Using cooling methods before exercise, such as consuming ice water or lowering body temperature beforehand;
Gradual acclimatization to high temperatures, a process that usually takes 7 to 14 days.

Scientists emphasize that exercising in hot conditions is not necessarily dangerous, but rising temperatures are making it increasingly difficult to maintain a regular physical routine.

In conclusion, experts warn that lack of heat adaptation and reduced physical activity could have significant consequences for public health in the decades to come.
