Heat index

For March, the heat index is evaluated at a sweltering 37°C (98.6°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
The heat index's values are generally associated with conditions in shade and light 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 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Shun overexposure. Protection from sun ravages is indispensable. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Always opt for UVA and UVB-resistant sunglasses on radiant days. Caution! The Sun's UV intensity grows with reflections off sand and water.
