Heat index

The heat index value for March is calculated to be a torrid 37°C (98.6°F). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.
Heat index evaluations are typically in the context of light winds and shaded environments. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Guard against overexposure. Protection from sun-induced harm is essential. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense. Be wary! Reflections from sand and water make UV radiation more intense.
