Heat index

For most parts of December, the heat index is evaluated at a blisteringly hot 40°C (104°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.
When referencing the heat index, its values are suitable for shady environments and light breezes. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are highly critical to babies and toddlers. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days.
