Note: The heat index, also known as 'apparent temperature' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. 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 especially crucial for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
