Primary Outcome Measures

Name	Time	Method
Severity of sleep disturbance measured using the Pittsburgh Insomnia Rating Scale 20[The Pittsburgh Insomnia Rating Scale 20 will be completed on the 8th day of each week (4 times in total ie days 8, 15, 22 and 29). ]

Secondary Outcome Measures

Name	Time	Method
Cycles of activity and rest during sleep, as measured using wrist actigraphy with the Actiwatch'[Wrist actigraphy to be worn for 29 consecutive days except during bathing];Heart rate variability measured using a heart rate monitor [Heart rate monitor to be worn on the seventh night of each week (4 times in total ie days 7, 14, 21 and 28). Intervention];Polysomnography to be measured with Zmachine [Sleep monitor to be worn on the seventh night of each week (4 times in total ie days 7, 14, 21 and 28)]
