Heat index

Throughout September, the heat index is appraised at a very hot 37°C (98.6°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. 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', marries air temperature and humidity to produce a value illustrating perceived warmth. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
