Heat index

During July, the heat index is estimated at a sweltering 95°F (35°C). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.
The heat index's values are generally associated with conditions in shade and light breezes. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days. Attention! UV strength is notably upped by the reflection of sand and water.
