- One study found that patients presented with headaches more frequently when there was high temperatures and low humidity, while higher humidity is correlated to lower incidence of headache. Moon phases had no effect on headache frequency.
- A Canadian study looking at over 100,000 ED visits for headaches found increased incidence of headaches when there were higher levels of air pollution/particulates, like smoke.
