Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
