The rise in nighttime temperatures poses significant health risks, particularly for vulnerable populations such as outdoor workers, older adults, and those without access to air conditioning. Prolonged exposure to heat without nighttime relief can strain the cardiovascular system and may contribute to long-term health issues like kidney damage. Additionally, the increased demand for air conditioning raises energy costs, creating financial strain for households already struggling to afford cooling. Urban heat islands exacerbate these challenges, as developed areas retain more heat overnight.
