Heat index

In July, the heat index is evaluated at a sweltering 39°C (102.2°F). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Fend off overexposure. Sun protection is vital. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
