Heat index

The average heat index in January is evaluated at a fiery hot 36°C (96.8°F). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', unifies temperature and humidity readings to offer a comprehensive feel of warmth. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold great significance to children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
