In this short but comprehensive book, Dr. Simon Atkins tackles the causes of sleeplessness, and what we can do about it. Full of practical tips and ideas, this book will be the start of a proper night's sleep. Research suggests that over half of us have bouts of insomnia and that persistent sleep deprivation can increase the risk of conditions such as diabetes, depression and high blood pressure. The University of British Columbia suggests that every hour of sleep lost at night may cost us one IQ point the following day. And it is often a long-term issue: a quarter of people with insomnia have suffered from it for more than 10 years.
