Heat index

Throughout January, the heat index is estimated at a life-threatening hot 45°C (113°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.
Always consider that heat index estimations are for light winds and places in the shade. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
