Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.

When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
