Heat index

Throughout August, the heat index is computed to be a blisteringly hot 104°F (40°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
Note that heat index values are valued for light wind and location in the shade. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
