Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
