Sleep issues highlighted in new book

Sleep issues highlighted in new book

Recent surveys show that 37% of New Zealand adults never or rarely get enough sleep, and one in four has a chronic sleep problem.

Sleep in the 24-Hour Society, the first book by noted New Zealand sleep scientist Dr Philippa Gander, provides a resource where non-specialists can learn about the science of sleep and the effects of the 24-hour society, and how to apply that knowledge in everyday life.

The book explains the circadian clock, which programmes our brains and bodies to prepare us for wakefulness during the day and sleep at night, and the stages and states of sleep.

As well as providing general advice for increasing your chances of a good night's sleep, Dr Gander looks at the specific challenges of shiftwork and jet lag. Examples range across different industries including pilots, air traffic controllers, oil rig workers, truck drivers, locomotive engineers, and anaesthetists. Dr Gander provides strategies for shiftworkers to help improve their own sleep, and maintain their alertness and safety in the workplace. Strategies for companies are also considered, including education and training, and roster design and management.

The overriding message? Make sleep a priority, says Dr Gander. 'Internationally there is mounting concern that inadequate sleep may be one of the biggest public health issues that we face. Insufficient sleep leaves us less functional during the day. It can make us irritable, weaken our immune systems, reduce our productivity and make us more accident-prone.'

Howard Davis Review: Smelling the Merchandise - The Death of Stalin

Having satirised British democracy with such devastating effect, Armando Iannucci has now turned his lens on the dangers inherent in Soviet authoritarianism. Every gag is girdled with fear and the bleak humour is so pitch black it could only have been pumped from deep underground. More>>

Howard Davis Review: The Creole Stylings of Cécile McLorin Salvant

"You only get a singer like this once in a generation or two," commented Wynton Marsalis, who has repeatedly hired her to front his jazz orchestra and mounted a 25 foot high portrait of her on the exterior of Lincoln Center. “She radiates authority. She has poise, elegance, soul, humour, sensuality, power, virtuosity, range, insight, intelligence, depth, and grace.” More>>

Max Rashbrooke Review: The King's Singers and Voices New Zealand

To be good at one thing is impressive; to be so versatile across a range of genres is truly exceptional. The latest incarnation of this six-strong male singing group includes Kiwi Christopher Bruerton, and it was a delight to hear him sing the solo on the achingly beautiful My Love Is like a Red, Red Rose.
