For generations, women have described the years before menopause as a time when sleep quietly unravels — and now, for the first time at meaningful scale, science has placed a number on that unraveling. Harvard researchers, drawing on 94,000 nights of wearable data from 338 women, have confirmed what lived experience long suggested: that perimenopause measurably fragments sleep, with 60 percent of participants showing increased nighttime wakefulness in the 18 months before their final menstrual period. The study does not offer a cure, but it offers something equally important — the dignity of v
