Continuous exposure and activity could induce a sense of tiredness and subsequently, heat cramps.Heat index readings emphasize conditions of light breezes and shaded spots. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are of high significance for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
