A study has shown a correlation between the sound of aircraft noise at night — not loud enough to wake you, but loud enough for a physical response — and a rise in blood pressure.
I’m not surprised. I grew up near an airport and the quality of my sleep was definitely dependent on the weather conditions and the flight patterns. I wouldn’t wake at night, but I was aware of being less rested in the morning. The same was true when we lived near San Jose airport. The air traffic was quiet enough on normal nights and mornings, but when the weather was bad and the flights were taking off in the opposite direction, the noise was considerably more disruptive, yet only on a subliminal level. I just remember feeling like I woke on the wrong side of the bed on those louder mornings.
