It is crucial to understand that heat index figures are for shade and gentle wind conditions. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
