Cold exposure during exercise can lead to an increased risk of dehydration. This may seem counterintuitive, especially since cold weather is often associated with less sweating. However, several factors contribute to this risk. In colder temperatures, individuals may not perceive the loss of fluid as readily as they would in warmer conditions, leading to insufficient fluid intake. Furthermore, cold air can also increase respiratory water loss, as breathing in cold, dry air causes moisture to be lost in exhalation. Maintaining hydration is crucial during exercise, regardless of temperature, to optimize performance and prevent complications.

Higher endurance performance is not a common effect of cold exposure; cold temperatures can impair muscle function and negatively influence exercise performance. Similarly, while cold conditions can potentially reduce metabolism temporarily, the body works hard to maintain its core temperature, which can lead to an increased metabolic rate in order to generate more heat. Lastly, the link between cold exposure and pneumonia risk is complex but not a direct result of exercising in cold conditions. Typically, pneumonia is associated more with illness or compromised immune function rather than exercise in cold weather alone.
