Insomnia is the term used for repeated difficulty falling asleep, waking during the night, or waking up too early which results in daytime sleepiness and poor daytime functioning. In Australia insomnia is most common in older adults and is becoming more common with dramatic increases over the past decade. It is estimated that in 2000, an alarming 18% per cent of women and 12.6% per cent of men aged 70 years and above suffered from insomnia virtually every night. The increasing prevalence of insomnia in the elderly population is concerning as it is estimated that by 2050 the number of persons aged 55 and over, could have almost doubled.

Consequences

Living with insomnia can be extremely debilitating as insomnia reduces quality of life and daytime functioning. Individuals with insomnia report lack of energy, irritability, poor work performance, memory difficulties and concentration problems.

The following are quotes posted on an internet group for insomniacs.

Ron (61) “I can say that insomnia has really made my life a living hell.” Anne (59) “Not being able to fall asleep is like torture”. Tom (63) “I ended up losing my job because I  couldn't function at work anymore”. Mosa (66) “I have become a recluse because I am too tired to do anything”.

In addition to the impact on quality of life and cognition, insomnia is associated with increased risk of heart disease, diabetes, relationship difficulties, accidents, falls and premature death.

Current Treatment

Other treatments include antidepressant medications and herbal remedies such as Valerian. Behavioural therapies such as sleep hygiene (sleep promoting behaviour) and cognitive behavioural therapy offered by psychologists are very effective and achieve good results, but there are often long waiting periods for Insomnia Clinics in Victoria and not all patients are able to access this treatment.

New Insomnia Research at the Austin Hospital

Recent studies have suggested that some forms of gentle exercise appear to be effective in promoting sleep.

The Institute for Breathing and Sleep (IBAS) in conjunction with RMIT University is currently conducting a trial to compare two forms of a 12-week gentle exercise program in those 55 years and over who have insomnia.
