Migraines are increasing in frequency and intensity among Americans: Could climate change be a reason? Although the number of Americans who have migraines has remained stable for the last 30 years, their impact on people’s daily activities — including missing social events or being less productive at school or work — has become much worse, according to a recent study. The report, published in early May in the journal Headache, analyzed 11 studies among U.S.
These weather changes may trigger a migraine by disrupting the balance of chemicals in the brain, like serotonin, according to the Mayo Clinic. Weather-related triggers include bright sunlight, extreme heat or cold, sun glare and high humidity. British researchers warned on Wednesday that extreme weather and heat fluctuations may aggravate neurological disorders such as stroke, dementia and schizophrenia.
