Heat index

The heat index value for August is appraised at a blisteringly hot 40°C (104°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
Remember that heat index calculations are made for conditions in the shade with light wind. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. 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.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
