Heat index

Throughout July, the heat index is estimated at a scorching 41°C (105.8°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.
When referencing the heat index, its values are suitable for shady environments and light breezes. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. 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 children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
