Note: The heat index, also known as 'feels like' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
