Note: The heat index, also known as 'real feel' or 'feels like', is a metric representing the sensation of warmth when air temperature and moisture come together. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
