Note: The heat index, also known as 'feels like' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. 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.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
