Note: The heat index, also known as 'felt air temperature' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. 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.
