In April, a narrative review from the Norwegian University of Science and Technology and published in The Journal of Headache and Pain revealed that each and every day "15.8% of the world's population had headache, and almost half of those individuals report a migraine (7%)." The Australian Standard starkly notes, "that means 1.1 billion people have a headache today." And as the study's lead author, Lars Jacob Stovner, said in a news release, "the prevalence of headache disorders remains high worldwide, and the burden of different types may impact many." .

"Each day, 15.8% of the world's population had headache, and almost half of those individuals report a migraine.".

More than half of us have had a headache in the past year, and as Northwestern Medicine reports, they are "more common, longer-lasting and frequent in women." We're also far more likely to suffer migraines.

They observe that while "headache disorders remain highly prevalent worldwide," and that they "found an apparent increase in prevalence of migraine," there are "large variation between study findings." Populations with greater awareness of migraine disorders, for example, unsurprisingly reported higher prevalence of them.

A 2019 Ball State University study found 35.6% of respondents said they were getting fewer than seven hours of sleep a night, with police officers and health care workers reporting they're getting by on five or six.
