Heat index

For most parts of July, the heat index is calculated to be a sweltering 98.6°F (37°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
