Milan-Cortina 2026: How Warmer Temps & Tech Will Impact Winter Olympics Performance
The Winter Olympics and Paralympics are set to take place in Milan and Cortina d’Ampezzo, Italy. Forecasts currently predict temperatures ranging from the upper 30s to mid-40s Fahrenheit (1 to 10 degrees Celsius) during the games.
Warmer Temperatures and Athlete Performance
These warmer temperatures are notably higher than typically expected for a winter sporting event, especially in a mountainous region. Athletes will likely need to adjust their equipment preparation accordingly. However, the conditions are still cold enough to impact both athlete and spectator physiology.
Athletes participating in outdoor events are accustomed to cold and unpredictable weather. While extreme cold is unlikely, the conditions will still affect performance. One concern is dehydration, which can be less noticeable in colder temperatures due to reduced sweating.
However, cold air also holds less moisture, requiring the body to use more water to humidify the air before it reaches the lungs. Athletes breathing heavily during competition may lose more body water than they would in warmer conditions. The body also narrows blood vessels in the cold to maintain core temperature, which can increase urine output.
The Science Behind Winter Apparel
Staying warm relies heavily on appropriate materials and construction. Many apparel companies utilize a three-layer system: a moisture-wicking base layer made of nylon or wool, an insulating middle layer of down or fleece, and a waterproof, breathable outer layer of polyester or acrylic.
The fabrics and coatings used in these layers often consist of polymers – long chains of molecules that can be both human-made and naturally derived. Engineers can modify synthetic fabrics, like nylon, with coatings to enhance properties like wind and water resistance.
Beyond conventional layering, “smart materials” like phase change materials are emerging. These materials automatically regulate body temperature by absorbing or releasing heat as they transition between solid and liquid states. While not yet widely used in athletic gear, NASA has experimented with them, and they are found in commercially available products like cooling bedding.
Considerations for Spectators
The impact of these conditions extends beyond the athletes. Thousands of people and support staff will be attending the outdoor events. Unlike the athletes, these individuals won’t benefit from the heat generated by physical activity and may be at greater risk of cold-related issues.
Spectators and staff are advised to drink plenty of water, wear multiple layers of clothing, and protect vulnerable areas like hands, feet, and noses. Colder temperatures trigger metabolic responses like shivering and the activation of brown adipose tissue, both of which increase calorie burn and potentially lead to increased hunger.
Frequently Asked Questions
What impact will warmer temperatures have on athlete performance?
Warmer temperatures will still affect athlete performance, even if extreme cold is avoided. Concerns include dehydration, increased water loss through breathing, and changes in blood vessel function that can affect fluid balance.
What is the three-layer system for winter apparel?
The three-layer system consists of a moisture-wicking base layer (nylon or wool), an insulating middle layer (down or fleece), and a waterproof, breathable outer layer (polyester or acrylic).
What are phase change materials?
Phase change materials are “smart materials” made of polymers and composite materials that automatically absorb or release heat to regulate body temperature as they transition between solid and liquid states.
