In her accessible book Sleep Sense, shut-eye expert Dr. Lederle explains how sleep works, why we need it, and how to improve our health through better quality sleep.

Sleep Sense takes us through the science behind our need for nightly restoration, showing what happens when we sleep and what goes wrong when we can't.

The book covers myriad topics from sleepwalking and nightmares right up to 'exploding head syndrome' - thankfully, not quite as dramatic as it sounds.

'Fatigue specialist' Dr Katarina Lederle has a PhD in the human body clock and is an expert on how light affects our sleep.

Dr Lederle encourages us to prioritize sleep as a mindful activity, easily as worthy of our attention as diet or exercise.

The book advises on minimising jet-lag when traveling long-haul, and also provides tips on more regular evening rituals.

The book breaks down the science into relatable concepts, from the familiar (REM/NREM) to the more obscure - hypnopompic jerks, for example.

The trove of helpful advice around regulating our sleep or managing insomnia is all the more effective for coming with irrefutable scientific backing.
