Expatriates healthcare customers might want to check-in with their doctor if they are having trouble sleeping.
According to a recent report, insomnia can affect an individual's health in a number of negative ways.
Indeed, the report from the Mental Health Foundation, entitled Sleep Matters, suggested a link between insomnia and depression, immune deficiency and heart disease.
On a social level, the condition is also likely to lead to poor relationships, low energy levels and a lack of concentration.
However, the report did highlight the fact that there is "no universal answer to the question of how much sleep a person needs".
But it is important for an individual to determine their ideal level of sleep in order to boost their health and energy levels.
Professor Colin Espie, director of the Glasgow University Sleep Centre, commented: "We can no longer just ignore the impact of sleep problems in this country.
"They are affecting our health, our economy, and our everyday happiness."
