Health Tip – Apr. 25 – Surprising Migraine Trigger
Dee Dee – Health Tip
New research demonstrates that lightning might be a possible trigger for migraines and severe headaches. Researchers at the University of Cincinnati found a 31 percent increased risk of headache and a 28 percent increased risk of migraine among individuals who suffer from chronic headaches on days lighting struck within 25 miles of their homes. This study was the first to show a potential link between lightning and headaches. Previous studies have reported conflicting links between headaches and other weather-related changes such as humidity and barometric pressure. The researchers recruited participants for the study from sites in Ohio and Missouri and asked them to record their headache activity in a daily journal for three to six months. Meanwhile, the researchers noted the location of lightning strikes within 25 miles of participants’ homes and recorded the magnitude and polarity of lightning current. Researcher Vincent Martin, M.D. suggested that the headaches could be triggered by electromagnetic waves emitted from lighting or the increases in ozone and other air pollution caused by the electrical discharge, as well as the release of fungal spores associated with lightning.
