A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels.

Heat index values are extremely significant for babies and toddlers. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
