London: Most migraine sufferers blame the onset of debilitating headaches on thunderstorms, rain and a sudden change in temperature.
But it turns out that they have got it wrong.
Volunteers in Austria were asked to keep diaries on their conditions and meteorologists then compared their notes with changes in the weather to see if they could find any evidence to back up the claims.
Experts at the University Clinic for Neurology in Vienna concluded that more down to earth factors were behind the onset of most headaches.
They said that menstruation, genetic aspects and a sudden relief from stress mattered more than changes in the weather like temperatures, the strength of the wind, atmospheric pressure levels and the amount of rain.
The combined study with Vienna’s Central Agency for Meteorology and Geodynamics based its findings on diaries kept by 238 people.
It was just the latest shot in the back and forth argument over how much influence the weather plays in causing headaches.
There is conflicting evidence in medical research. In one study involving 7,000 patients published by doctors in the US, investigators found that higher ambient temperatures increased the risk of headaches.
For every five degrees Celsius rise in temperature, there was a 7.5 per cent increased risk of an emergency department visit for severe headache.
