A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
