Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees.

Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
