Note: The heat index, also known as 'feels like' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to 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 body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
