Think Less, Sleep More: From Panic & Perfectionism to Stress-Free Sleep

A smart and sometimes counterintuitive (who cares when you go to bed?) guide that will solve readers' sleep anxiety once and for all!

If there's anything worse that not getting sleep, it's lying awake with a scare-face staring at the ceiling worrying about it. Here's Romiszewski's--a sleep physiologist and founder of the UK's Sleepyhead Clinics -- promise: "This book is your guide to liberating yourself from the endless cycle of sleep anxiety and obsession. By the end, you'll have regained control - not through perfection, but by letting go of the need to constantly manage your sleep. Sleep will start working for you, not as something to fear or fix, but as your natural ally. And best of all, it will no longer dominate your thoughts."

THINK LESS, SLEEP MORE is a sensible take on sleep with some counterintuitive twists to current accepted dogma, such as that we all need more sleep and that segmented sleep -- aka waking up in the middle of the night -- is a killer. It's a health and wellness sigh-of-relief book: there are some readjustments to make, both mental and physical, but a key takeaway is that whatever you're doing now is probably better than you think.

Among other counterintuitive insights, Romiszewski reveals:
--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 neither ruin the next day, nor, necessarily, your health, and that variability is normal
--That sleep isn't fragile--it's adaptable, resilient, and smarter than any hack you could throw at it
--The myth of 8 hours
--The power of light

For an audience who found Matthew Walker's "Why We Sleep" a bit daunting, Romiszewski's is the sensible, seasoned, calming voice you want to think of a 3AM.
