Most people think they know how much sleep they need… but do they really? 🤔 As a sleep doctor, I took to Times Square with a challenge: Guess the recommended number of hours of sleep—and win a blackout sleep mask. Sounds simple, right? You’d be surprised by the answers. 🔍 The truth? Adults need 7–9 hours of quality sleep for optimal brain function, memory, and mood. But here’s the thing—light exposure at night can throw all of that off. That’s why I partnered with @mantasleep, the brand I trust for blackout sleep masks that actually block 100% of light. ✅ Better melatonin production ✅ Deeper rest ✅ Real recovery Use my code: SleepDrChris at mantasleep.com for a discount—and see if blackout sleep makes a difference for you.
