The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
