Is there a concern for Hypothermia during Exercise, and how cold is too cold?

Published by admin on

While channeling your inner Rocky Balboa in chilly weather may seem invigorating, there’s a potential risk to your health or even life when facing the frost.

The current weather is undeniably cold, and with a significant portion of the population aspiring to improve fitness this year, the pressing question arises: what temperature is considered too cold? Engaging in physical activities, such as running or cycling, can make it challenging to perceive changes in body temperature. A recent study immersed 11 healthy young men in cold water, comparing rest to low-intensity cycling. Surprisingly, exercise slightly blunted their shivering response and ability to feel the cold, raising concerns about potential risks in cold air.

Hypothermia, occurring when the body loses heat faster than it can generate it, is a medical emergency with a body temperature drop below 35°C (normal being around 37°C). Although not common among exercisers, even seasoned runners faced hypothermia in the 2018 Boston marathon due to unusually cold temperatures.

Dr. Clayton Cowl, a pulmonologist at Mayo Clinic in Minnesota, emphasizes the importance of preparedness. Unplanned stops during a run, whether due to injury or exhaustion, can leave individuals unprepared for the cold. Dressing in layers, covering hands and head, and recognizing the potential for frostbite in extremities due to temperature drops are crucial precautions.

Recognizing the warning signs of hypothermia, such as uncontrollable shivering, loss of coordination, slurred speech, or confusion, is essential. If these signs appear, prompt action is required to get out of the cold, remove wet clothing, and avoid attempting to warm up too quickly, which may lead to skin damage or heart irregularities. Warm drinks and layering blankets on a shivering person are recommended. In severe cases, especially if someone loses consciousness, it is vital to move them off the cold ground, monitor their breathing, and seek medical attention promptly.

Prevention remains the best approach. Winter activities can be enjoyable with proper preparation—wearing layers, carrying warm drinks, and informing a friend about your plans. For winter swimming, ensure a proper cold-water induction with an expert guiding you through safety measures. While outdoor activities offer numerous benefits, ensuring proper planning is key to a safe and enjoyable experience
