Hot tips for this year’s summer holiday

Extreme heat exerts tremendous stress on the human body, impacting both physiological functions and performance. High temperatures force the body to work harder to cool down, leading to quicker depletion of energy reserves, reduced endurance and decreased strength. The central nervous system is also affected, causing slower reaction times and impaired cognitive function.

"Young children and the elderly are more prone to heat illness as their body metabolisms don't accommodate a drastic temperature change as well," notes Duchateau. "In particular, older people often have increased numbers of medical conditions and are often on prescription medications that may make it more difficult for their bodies to regulate temperature naturally."

The International Olympic Committee (IOC) and Paris 2024 organizers know the risks and are implementing strategies to combat the potentially debilitating effects of elevated temperatures. Severe heat can hinder athletes' ability to perform and increase the risk of mistakes and injuries. Athletes risk heat stress, which can lead to dehydration. Dehydration can cause dizziness and impaired performance. Severe cases can result in heat cramps, heat exhaustion and heat stroke, a life-threatening condition where the body's temperature regulation system fails.

Organizers are monitoring long-term weather models to anticipate and prepare for heat waves. This is backed by comprehensive guidelines for managing heat-related illnesses, ensuring that medical teams are well-prepared for emergencies. These guidelines include rapid cooling techniques and detailed emergency response protocols to manage heat-related incidents swiftly and effectively.

The competition schedule has been adjusted to avoid the hottest parts of the day. Events are now scheduled in the mornings and evenings when temperatures are cooler, reducing the risk of heat-related health issues for athletes. Multiple hydration and cooling stations will also be set up across all venues, providing cold drinks and shaded areas for athletes, staff and spectators to rest and stay hydrated.
