Note: The heat index, also known as 'real feel' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
