Insomnia

Insomnia is a sleep disorder that prevents the affected individual from being able to sleep, fall asleep, and/or, stay asleep.

Over one-third of people experience insomnia, but often, less than 5% of these people actually require treatment. This condition can occur at any age, but it is most common among the elderly.

There are two types of insomnia: 

Primary insomnia

Primary insomnia occurs when the individual is having sleep difficulties that are not related to any medical conditions. This is often known as ‘acute insomnia’ and will often be caused by: significant stress (job loss, divorce etc), emotional or physical discomfort, environmental factors (such as light, noise, temperatures etc), some medications, and interferences in usual sleep patterns (such as jet lag, change in shifts from day to night etc).

Secondary insomnia

Secondary insomnia relates to the lack of an individual’s ability to sleep due to other external factors such as medical problems, pain, medications, or substance abuse (for example, alcohol). This type of insomnia generally lasts longer and is often called ‘chronic insomnia’. This condition becomes ‘chronic’ when the individual has insomnia for at least three nights a week for over a month.

Causes of chronic insomnia are: medical conditions (such as asthma, depression, anxiety, arthritis, or cancer), chronic stress, substance abuse, chronic pain, or medications.

SYMPTOMS

TREATMENT

Acute insomnia may likely not require treatment. Mild cases can be prevented by practicing good sleep habits. If your insomnia is affecting you too much during the day, sleeping tablets may be prescribed. Treatments for chronic insomnia may include: fixing or managing the underlying medical conditions, or behavioural therapy.
