Nearly two thirds of us are suffering from sleep deprivation.
Poor sleep can be associated with accidents, lower work productivity, and may also worsen medical and psychological conditions. Sufferers are at an increased risk of depression, a compromised immune system, and inertia. Still, and even though it is treatable, insomnia is one of the most under-diagnosed and under-treated disorders of the central nervous system.
Women tend to be more prone to insomnia than men, with poor sleep usually associated with the menstrual cycle, menopause and pregnancy.
Ageing also tends to bring a change in sleeping patterns, with elderly people often suffering from lighter, more fitful sleep.
Patients with a history of depression are also more susceptible to insomnia.
