Heat index

The heat index value for March is evaluated at a sweltering 38°C (100.4°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. 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 gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
