The heat wave poses significant health risks, particularly for vulnerable populations such as the elderly, children, and those without access to cooling. Prolonged exposure to extreme heat can lead to heat exhaustion, heat cramps, and heat stroke. Urban areas may experience compounded effects due to heat retention in concrete and asphalt. Over 100 million people are under major or extreme heat risk advisories, with cities like Washington, DC, and New York City expected to see consecutive days of record-breaking temperatures. The combination of high daytime temperatures and warm nights will make it difficult for the body to recover, increasing the likelihood of heat-related illnesses.
