The heat dome poses significant risks to public health, particularly for vulnerable populations such as the elderly, children, and those with pre-existing health conditions. Prolonged exposure to high temperatures can lead to heat-related illnesses, including heat exhaustion and heat stroke. Urban areas like Manhattan are especially affected due to the heat-retaining properties of concrete and asphalt, which can make temperatures feel even hotter. Residents are advised to limit outdoor activities and stay hydrated to mitigate these risks.
