Note: The heat index, also known as 'felt air temperature' or 'real feel', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. 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 largely significant for babies and toddlers. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
