Many people struggle with inadequate sleep at some point in their lives. Yet, because the problem does not always affect their daily functioning, many never consult a doctor, therapist, or seek treatment.

Insomnia is a sleep disorder characterised by the inability to fall asleep, stay asleep, or waking up early in the morning for a prolonged period. It is a very common disorder, affecting between 6 and 40 per cent of the population. Insomnia can affect quality of life just like conditions such as depression and heart failure, and so it should not be left unattended. Untreated insomnia can also lead to or worsen other mental disorders, and impact physical health by increasing predisposition to accidents and appetite.
