Patrick Fuller, associate professor of neurology at Harvard Medical School told Tech Insider: “People throw that word around, but most cases of insomnia are not primary insomnia.”
If you actually go to a sleep clinic and do the whole rigmarole of getting hooked up to electrodes and monitors and spending a (somewhat uncomfortable) night in the clinic, you’ll probably find that you don’t actually have insomnia.
Of the people that come in with a primary complaint of insomnia, Fuller said, only 15% or so are truly insomniac for a brain reason. “They just biologically can’t sleep.”
