Low energy levels
Irritability, and
Lack of concentration Around 30 to 40 percent of adults experience some level of insomnia within any year, and of these around 10 to 15 percent suffer from severe or chronic insomnia. As we have already seen, insomnia increases with age but is also more commonly experienced by women. Sleeping disorders occur from infancy through to old age with a significant rise in incidence in old age. Most people dont consult a doctor about their problem or resort to sleeping pills or tranquilizers to help. Lack of sleep accumulates into what is known as a sleep debt, with many people carrying a huge sleep debt without realizing. People with greater sleep debts are slower to recover from illness and are more vulnerable to catching infections, viruses and other illnesses. How is insomnia diagnosed? If you have disturbed sleep and think you have insomnia it is important to see a doctor. You may be asked to keep a sleep diary for a week or two, noting the patterns of your sleep (or lack of them) and your daily routines. You will need to discuss your sleep diary with your doctor. It may be necessary for your doctor to do a physical examination as well as taking notes of your medical history. In some cases, you may be referred to a specialist sleep center.
