Sleepwalking or somnambulism: Engaging in activities that are normally associated with wakefulness (such as eating or dressing), which may include walking, without the conscious knowledge of the subject
Snoring: Loud breathing patterns while sleeping, sometimes accompanying sleep apnea
Sleep disorder’s treatment from a behavioural standpoint:
First, the underlying cause is identified and eliminated. Behavioural therapy is then the most effective and longest lasting, but also the most time-consuming. Good sleep hygeine includes basically no stimulating substances (caffeine) or activities (exercise) before bed.
Stimulus control therapy involves breaking associations of wakefullness with the sleep environment – otherwise the body will become conditioned to think its “awake time” in the bedroom.
Another behavioural approach involves sleep restriction. A sleep log is kept to determine how much the patient sleeps currently, then they are only allowed to be in bed for that amount of time.
If they don’t sleep much during that time, tough luck! they’ve got to get out of bed. After a couple nights they’ll be so sleep deprived that they’ll sleep 90% of the allotted time, then you can slowly progress to a more normal sleep interval.
