Heat index

The heat index value during January is calculated to be a fiery hot 38°C (100.4°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.

Guard against overexposure. Protection from sun-induced harm is essential. 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. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
