Poor sleep may develop for no apparent reason. However, there are a number of underlying causes.

Other illnesses
Insomnia can be caused by an underlying physical condition causing involuntary movement, pain or discomfort. Examples include arthritis, coughing and itching.

Temporary problems
Disruptions within the sleeping environment or to bedtime routines can cause restless sleep. Factors include noise, snoring, jet lag, a strange bed, anxiety or depression.

Loss or worry caused by events such as bereavement can also make sleeping difficult.

Such as alcohol, caffeine and nicotine can interfere with sleep as can some prescribed medicines. Sleeping problems can result from the effects of drugs such as anti-depressants or steroids.

The first step of treatment is to identify the underlying causes and to treat them. For example if insomnia is being caused by depression, then once the depression is treated, the insomnia will often disappear without further medical help.

Non-drug treatments are usually the preferred first course of action. These treatments include: Patient education about sleep and relaxation. Lifestyle advice including restrictions on caffeine, nicotine and alcohol.

Drug treatment may be considered in a number of cases, either because the symptoms are particularly worrying or to alleviate short-term restless sleep. There are a number of conventional and herbal products that may be recommended by the pharmacist for short-term use. These tablets may cause drowsiness the next day so always read the label and don’t drive if you are affected.
