Heat index

Throughout May, the heat index is evaluated at a torrid 38°C (100.4°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
Heat index details are generally centered around shaded locations and a mild breeze. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', arises from combining readings of air temperature and relative moisture content. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
