Sleep Disorders Are Linked With Depression


sleep disorder depression linkThere are many causes of depression, and one of them could be because of living alone. Based on a research, it was known that living alone increase depression risks. But a more unique relation was discovered recently.

According to a recent research, women who suffers from sleep disorders, such as experiencing short breathing or her breathing stops briefly during sleep, are 5.2 times more likely to experience depression when compared to women who do not experience sleep disturbances.

While in men, those who suffer from sleep disorders are 2.4 times more likely to experience depression when compared to men who did not experience the disease. This is a result of a research conducted by scientists at the Centers for Disease Control and Prevention (CDC) USA.

In the study at the CDC, the volunteers who also have other breathing disorders during sleep are also at high risk for depression. But this relation does not apply for people who snores. The scientists found no increased risk of depressive tendency in those who snore.

“Snorting, gasping for breath or stop breathing during sleep is associated with almost all the symptoms of depression, including feelings of hopelessness and feeling like a failure,” said researcher Anne Wheaton, an epidemiologist at the CDC according to LiveScience.

The researchers stated that both depression and breathing problems during sleep is something that is common, and both of these often goes undiagnosed. They added that the screening of people who have the disorder would be useful to help better treatment.

The researchers included other factors that may affect the results of research such as age, sex and weight. According to the scientists, the results are in accordance with results of other studies. The results of this study was published in the April 2012 issue of the ‘Sleep’ journal.

This study found a relationship, but not a causal link. However, the researchers write evidence from other studies showing that breathing problems during sleep contribute to the development of depression.

For example, a previous study showed the relationship between the severity of breathing problems during sleep with a strange development of depression later in life. Other studies showed that those who undergo treatment for sleep disorders had improvement of their depressive condition.

“Professional mental health field often ask about sleep problems like sleep is not refreshing and insomnia, but tend not to realize that (interruption of breathing during sleep) may have an impact on the mental health of their patients,” the researchers said in conclusion.

Although the relationship between the two is not clear, but it can be explained by the fact that those who experience respiratory problems, sleep interrupted or possibly due to lack of oxygen in the blood during sleep.
