Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down.

When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
