Why City Summers Ruin Your Sleep
• The urban heat island effect makes city nights 2-5°F warmer than rural areas, disrupting sleep.
• Concrete, rooftops, and traffic trap daytime heat, releasing it slowly at night, causing restless sleep.
• Lack of sleep during urban summers can lead to increased stress, weakened immunity, and impaired cognitive function, especially for children and older adults.
Urban summers and their impact on sleep
Urban summers pose significant challenges to sleep quality. The phenomenon known as the "urban heat island effect" causes cities to experience notably warmer nights compared to their rural counterparts. This effect can raise nighttime temperatures by 2 to 5°F (approximately 1 to 3°C) in urban areas, creating uncomfortable conditions that disrupt sleep patterns.
