In France, night flight restrictions at airports vary from platform to platform. For example, at Paris-Orly, departures are prohibited between 11:15 p.m. and 6:15 a.m. and arrivals between 11:30 p.m. and 6:30 a.m. According Public Life website, in Beauvais-Tillé, a curfew applies between midnight and 5 a.m., and in Bâle-Mulhouse, between midnight and 5 a.m. for arrivals and between midnight and 6 a.m. for departures. Problem: Being exposed to even moderate aircraft noise can interfere with sleep.
Sleep: Adults need 7-9 hours of sleep per night
“Sleep is essential for overall health and well-being, including physical and mental functioning. Insufficient sleep can increase the risk of cardiovascular disease, depression, diabetes, cancer and many other health problems. Health professionals say most adults need seven to nine hours of sleep each night to function healthily.” indicated researchers from the Boston University School of Public Health (USA) in a statement.
In one study, the team looked at the aircraft noise exposure and reported sleep disturbances of more than 35,226 nurses living around 90 US airports. Every five years, from 1995 to 2015, it focused on two measurements: a nighttime estimate that assesses aircraft noise when residents are sleeping, and a day-night estimate that measures the average noise level over a 24-hour period and applies a 10 decibel (dB) adjustment for noise generated by aircraft at night, when background noise is low.
Aircraft noise exposure is associated with short sleep duration
According to the results, the likelihood of sleeping less than seven hours increased as exposure to aircraft noise increased. “Exposure to aircraft noise greater than or equal to 45 dB was associated with a 23% increased risk of short sleep duration, but was not associated with poor sleep quality,” can we read in the results, published in the journal Environmental Health Perspectives. The authors recalled that the noise of a whisper is 30 dB, that heard in the library is 40 dB and that of a normal conversation at home is 50 dB.
“Cargo operations use louder planes” that often fly at night
“There was a relatively strong signal between aircraft noise and the two aspects of disturbed sleep near cargo airports. This story likely doesn’t end there, as cargo operations tend to use larger, older, busier and therefore noisier aircraft, which often fly during the hours of the night.In addition, the amount of cargo shipped by air has steadily increased over the past two decades, can “Being due to the rise of online commerce. If this trend continues, aircraft noise could impact more people,” warned Matthew Bozigar, author of the study.
