People who suffer from insomnia should try to stop worrying about it, despite the fact that the condition can lead to other ailments that could require treatment through international private medical insurance policies.
Social psychologist Dr Sandra Wheatley said being concerned about a lack of slumber "can affect your ability to sleep continuously" and result in a larger number of restless nights.
She recommended insomniacs try to look on "the bright side", stating if people make a note of how much sleep they get, they might be surprised at how much it is.
"That in itself can be reassuring," she remarked, noting this can also improve rest and reduce the impact of insomnia.
Dr Wheatley suggested that insomniacs could aim to sleep for six hours in every 24, stating that they could "think about each day as a unit of time".
Research by international healthcare teams has linked a lack of sleep to a huge number of illnesses, including hypertension, stroke, cancer, Alzheimer's, Parkinson's disease, arthritis, hypertension, gastroesophageal reflux disease, lung problems and heart failure.
