The realm of lost luggage and lost sleep
It may be convenient to live near an airport if you’re a frequent flyer, but it really doesn’t help your sleep numbers.
The first look at how such a common sound affects sleep duration showed that people exposed to even 45 decibels of airplane noise were less likely to get the 7-9 hours of sleep needed for healthy functioning, investigators said in Environmental Health Perspectives.
How loud is 45 dB exactly? A normal conversation is about 50 dB, while a whisper is 30 dB, to give you an idea. Airplane noise at 45 dB? You might not even notice it amongst the other noises in daily life.
The researchers looked at data from about 35,000 participants in the Nurses’ Health Study who live around 90 major U.S. airports. They examined plane noise every 5 years between 1995 and 2005, focusing on estimates of nighttime and daytime levels. Short sleep was most common among the nurses who lived on the West Coast, near major cargo airports or large bodies of water, and also among those who reported no hearing loss.
The investigators noted, however, that there was no consistent association between airplane noise and quality of sleep and stopped short of making any policy recommendations. Still, sleep is a very important, yet slept-on (pun intended) factor for our overall health, so it’s good to know if anything has the potential to cause disruption.
