Description
The part of your health nobody asks about
Your doctor asks whether you smoke, whether you exercise, what you eat and how much you drink. Very few ask how you sleep, even though short and disrupted sleep are consistently associated with cardiovascular problems.
These 436 pages fill that gap.
Practical, and honest about limits
Twelve chapters on what genuinely shifts sleep: timing and consistency, light exposure, caffeine and alcohol discussed realistically rather than as prohibitions, and shift work — which affects an enormous number of people and is usually ignored by sleep advice written for people with ordinary schedules.
It is also clear about what good sleep habits can and cannot achieve, which most popular writing on sleep is not.
When to ask for a medical assessment
One chapter is about obstructive sleep apnoea — loud snoring, witnessed pauses in breathing, waking unrefreshed, morning headaches. It is common, frequently undiagnosed, and strongly linked to high blood pressure and irregular heart rhythms. If several of the signs apply, the book says plainly to ask a doctor about assessment rather than trying to manage it alone.
Suits
Anyone with a cardiac diagnosis or cardiac risk factors, shift workers, and clinicians who would like to recommend something specific.

Why sleep is a cardiovascular measurement
The link between sleep and your heart is mediated through blood pressure that fails to dip overnight, sympathetic activation, glucose handling and inflammation. The book explains these mechanisms in plain terms and sets out what short sleep, irregular timing and fragmented sleep do to cardiovascular risk over years rather than nights.
Apnoea, shift work and getting help
Obstructive sleep apnoea is given full treatment: the features that should prompt testing, what a sleep study involves, what treatment does and does not achieve for cardiovascular outcomes, and why partners often notice first. Shift workers get their own chapter with realistic strategies rather than advice to sleep at night. Practical sleep improvement is evidence-based throughout, and the book is clear about when sleep and your heart needs a doctor rather than a routine change.
