Heat index

January's mean heat index is calculated to be a fiery hot 37°C (98.6°F). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and 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 primarily vital for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Take every vital safeguard, as unprotected skin and eyes may suffer burns rapidly. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat. Broad-spectrum SPF 30+ sunscreen must be generously applied and reapplied every two hours or post any outdoor activity or swim. Take warning! Reflective sand and water surfaces intensify the Sun's UV rays.
