Note: The heat index, also known as 'feels like' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
