An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important 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.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
