Heat index

June's heat index is computed to be a sweltering 35°C. Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. 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 are quite important for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. 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 heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun. Alert! Sand and water increase UV exposure due to their reflective properties.
