With extended exposure and activity, one might feel exhausted and experience heat cramps.Be advised, the heat index considers values for conditions in shade and with a light breeze. 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 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
