Heat index

The heat index in May is appraised at a fiery hot 96.8°F (36°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
