We found the real sleep killer. It’s not just about screens, it’s how hooked you are on the content. @eightsleep studied 240+ members using their phones before bed. People who viewed high-attention content slept 12 minutes less each night. Across a week, that’s 1.5 hours of lost sleep. How long you viewed the content didn’t change this effect. What mattered was how engaging the content was, low-attention content showed less impact on sleep.
