Sleep: its importance and the effects of deprivation on surgeons and other healthcare professionals.

As clinicians, we sometimes fail to look after ourselves properly and do not regularly eat healthy foods or drink enough. Sleep is another factor that we often neglect. A lack of it can compromise our personal health and performance at work, and the "sleep debt" that results when this is chronic can take far longer to recover from than one might think. Now that junior doctors work more shift rotas and senior colleagues have onerous on-call responsibilities, we all need to be aware of the effects of sleep deprivation, which can lower the mood and motivation, weaken leadership, and result in more clinical errors. In this review we consider what might constitute enough sleep, the consequences of inadequate sleep, and how these might be addressed for surgeons.
