The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. 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 hold particular importance for children. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
