Note: The heat index, also known as 'apparent temperature' or 'real feel', gives an indication of how one might feel in terms of heat after considering humidity. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical for babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
