Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
