Heat index

The heat index in January is computed to be a torrid 38°C (100.4°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Follow precautions and abide by sun safety rules. Deterrence of sunburn is imperative. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation. Be cautious! Sand and water surfaces make the Sun's UV rays more potent.
