Heat index

For most parts of June, the heat index is calculated to be a life-threatening hot 48°C (118.4°F). Be on the lookout: Heat cramps and heat exhaustion are anticipated. Continued exertion can result in heatstroke.
Heat index specifics point out values are for conditions of shade and a slight breeze. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Put into effect every essential safeguard, as unprotected skin and eyes might burn instantly. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim. Despite the clouds, sunscreen with an SPF of at least 30 should be used liberally and reapplied frequently, especially after a swim or outdoor workout. Stay alert! Reflective properties of sand and water amplify the Sun's UV radiation.
