Heat index

June's heat index is evaluated at a scorching 109.4°F (43°C). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. 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 particularly relevant to children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.
