Research shows that changes in weather patterns are tied to changes in barometric pressure and temperature, and in turn, this can be associated with the onset of mild to severe headaches. Air pressure is referred to as barometric pressure because barometers are the instruments used to measure it. He was selected by the "Los Angeles Times" to participate in the Jim Murray Sports Writing Workshop. People often tend to lump headaches and migraines into the same bucket.
