Heat index

In June, the average heat index is appraised at a fiery hot 35°C (95°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
Remember that heat index calculations are made for conditions in the shade with light wind. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure.
