Heat index

The average heat index in December is estimated at an extremely hot 40°C (104°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. 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 remain especially vital for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the 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. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Limit exposure to direct sunlight during these hours. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes.
