Stephanie Romiszewski never worries about sleep - ever. And she has helped over 10,000 patients do the same. A clear-eyed and passionate antidote to both individual sleep anxiety and our current obsessive, perfectionist culture, her first book will unpack the science and fundamentals of sleep - including misunderstood concepts such as sleep drive, sleep debt and sleep sensitivity - and arm readers with simple tools for how we can each improve something we spend a third of our lives doing. Stephanie will reveal, among other counterintuitive insights: - The importance of a consistent wake time rather than a rigid bedtime. - How to trust your body's natural sleep drive and rhythms. - That 'bad' nights don't ruin your health, and variability is normal. - That sleep isn't fragile - it's adaptable, resilient, and smarter than any hack you could throw at it.
