Many poor sleepers come to our service worrying that they are at risk of serious physical illness and even death. It\u2019s easy to see why these worries exist, with there being so much frightening information at our fingertips about the link between poor sleep and health.

Contrary\u00a0to popular belief, an important paper published recently,\u00a0 suggested that\u00a0Insomnia<\/a>\u00a0does not increase mortality risk.\u00a0 Nicole Lovato and Leon Lack at Flinders University conducted a\u00a0review\u00a0of studies that investigated the link between insomnia and mortality<\/a>. \u00a0The review considered data from\u00a037 million participants\u00a0<\/em>and followed them up for an average of 11.6 years (of course, further research is needed with a longer follow-up period).

So how come there are so many seemingly conflicting conclusions on this issue of long term impact of insomnia? It\u2019s enough to make anyone have a sleepless night getting to the bottom of it. To answer this it’s important\u00a0to understand\u00a0that\u00a0short sleep duration<\/em>\u00a0and\u00a0insomnia<\/em>\u00a0are not the same thing.\u00a0 \u00a0<\/p>\n\n\n\n

One issue with the reporting of research is that short sleep duration <\/em>and i<\/em>nsomnia<\/em> are terms that are used interchangeably.<\/p>\n\n\n\n

\u200bResearch on the impact of long term short sleep duration does indeed find links with poor health outcomes and mortality. Although objective short sleep duration is characteristic of some types of insomnia, research suggests that this may only be 40-50% of insomnia sufferers. <\/p>\n\n\n\n

Insomnia isn’t defined by how much sleep the person gets, a person with insomnia, may, on average, be sleeping very little or quite a lot. The typical pattern of insomnia is lots of variability night to night \u2013 for example, a poor night (or run of poor nights) being followed by a longer catch-up sleep.  It is often the case that people with insomnia believe that they sleep less than they actually do. Studies suggest that people with insomnia sleep on average around 6+ hours per night which is above the risky range for short sleep duration.  <\/p>\n\n\n\n

Another issue which may have strengthened the belief that insomnia increases mortality risk is that the studies that have found an association between insomnia and mortality are headline grabbers and more likely to be reported on and shared. 

This is not to say that Insomnia is a condition to be ignored, far from it. Insomnia reduces quality of life and productivity, increases health care usage, risk of depression, anxiety and diabetes.

Thankfully there are effective treatments, with Cognitive Behaviour Therapy-Insomnia (CBT-I) being the recommended first line treatment.<\/a> This is a non-medical treatment, which is ideal for this condition.  CBT-I aims to help  those with insomnia to develop coping skills, helpful attitudes about sleep and modify poor habits. An important aspect of insomnia that we see every day is the belief that insomnia is detrimental to health. This increases worry about sleep, and  put simply, the more people worry about their sleep, the less well they sleep. This new study adds weight to the reassurance that we can provide to insomnia sufferers.

Finally but importantly, Lovato and Lack found that while Insomnia did not increase mortality risk, that use of medicines designed to treat the condition did slightly increase mortality risk. Sleeping pills are only designed for short term use (a few weeks) and can cause problems if taken in the longer term.<\/p>\n","protected":false},"excerpt":{"rendered":"
