Note: The heat index, also known as 'feels like' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth.

Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
