If the body can not disperse the excessive heat and body temperature reaches conditions of hyperthermia, above 99.5☏ (37.5☌) to 100.9☏ (38.3☌), thermal conditions are potentially life-threatening. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Excessive warmth is eliminated from the body by evaporation of sweat. The human body normally cools itself by perspiration. Thirst is a late sign of dehydration - it is vital to remain hydrated, particularly during prolonged physical activities. Children are often less aware of the need to rest and re-hydrate. Heat index values are especially crucial for babies and toddlers. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. This effect is subjective, depending on the activity and individual's heat perception influenced by various reasons (metabolic differences, wind, clothing). Note: The heat index, also known as 'felt air temperature', 'real feel', 'apparent temperature', or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees. Note that heat index values are valued for light wind and location in the shade. Sustained activity may result in heatstroke. Take extra precautions, as heat cramps and heat exhaustion are possible.
