Heat index

The heat index value during September is evaluated at a sweltering 37°C (98.6°F). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', gives a temperature feeling by integrating air temperature and humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
