Heat index

The average heat index in October is computed to be a scorching 40°C (104°F). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.
Heat index data is primarily for areas with shade and subjected to light winds. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
