Heat index

March's average heat index is appraised at a blistering 41°C (105.8°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
When assessing, remember that heat index measurements are for light winds and shaded spots. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. 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.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage. Take note! Sand and water reflections strengthen the Sun's UV exposure.
