Nightly fireworks cause many to lose sleep, affecting health

In cities like New York, Boston, Los Angeles, Chicago and San Francisco, residents have been reporting daily rounds of fireworks for weeks now, some of which begin as early as 7 p.m. and continue until the morning. While it remains unclear exactly why fireworks have suddenly spiked, or where they’re coming from, doctors say there is no debate about how they may be affecting those who are losing sleep as a result.
