"Night Air" is a song by British singer-songwriter Jamie Woon released as the lead single from his debut album, Mirrorwriting.

Prior to the late 19th century, night air was considered dangerous in most Western cultures. Based on “zymotic” theory, people believed vapors called “miasma” (plural "miasmata") rose from the soil and spread diseases. Miasmata was believed to come from rotting vegetation and foul water—especially in swamps and urban ghettos.
