Throughout January, the heat index is estimated at a sweltering 38°C (100.4°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Know that the heat index computations account for shaded terrains and slight winds. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
