Heat index

January's average heat index is appraised at a fiery hot 39°C (102.2°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical 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.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. 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. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Employ a wide-brim hat for potent defense against up to 50% of UV rays. After a swim or an outdoor workout, generously apply and regularly reapply a sunscreen with at least SPF 30, even if the day is cloudy. Notice! The reflection of water and sand increases the UV radiation significantly.
