What are some effective strategies for cyclists to avoid dehydration during cold weather training when the typical indicators of dehydration, such as excessive sweating and thirst, are often masked by the cold temperatures. Given that the human bodys ability to regulate its core temperature is compromised in cold conditions, is it even more crucial to prioritize hydration during this time, and if so, what are some practical ways to do so. Should cyclists adopt a preventative approach to hydration, drinking fluids at regular intervals regardless of thirst, or are there more reliable methods for monitoring hydration levels in cold weather conditions.
