    NYT: A recent study found an association between traffic noise exposure and an increase in abdominal body fat. But it was only an association.

    I'm inclined to think it is a case of confusing correlation with causation (e.g. ice cream sales are responsible for a spike in summer crime).

    That said, this sounds pretty plausible:
    "The study’s authors offer a number of potential reasons why noise might cause weight gain, including the possibility that it disrupts people’s sleep and that it causes stress. Stress causes the body to produce a hormone called cortisol. Overproduction of cortisol can cause body fat to accumulate in the abdomen."
