Note: The heat index, also known as 'feels like' or 'real feel', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees.

Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
