Heat is one of the leading weather-related killers in the United States, resulting in hundreds of deaths and fatalities each year, the National Weather Service reports.
Young children and infants are particularly vulnerable to heat-related illness and death because their bodies are less able to adapt to heat. Older adults, particularly those with pre-existing medical diseases or who take certain medications, or who have limited mobility or may live alone can also be susceptible.
