Heat index

For most parts of January, the heat index is appraised at a sweltering 35°C (95°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Ward off overexposure. Defence against solar harm is crucial. 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. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized. Stay alert! Reflective properties of sand and water amplify the Sun's UV radiation.
