(Utah People’s Post) – Sleep problems are often caused by various mental illnesses, such as depression or post-traumatic stress disorder, but a new research shows interchangeability between sleep disorders and depression. Apparently, having trouble sleeping can also be a trigger.
Researchers from the University of Adelaide and the Adelaide Institute for Sleep Health examined levels of sleepiness throughout the day in almost 2,000 Australian men aged between 35 and 83.
It turned out that those exhibiting severe daytime sleepiness had 10 percent more chances of becoming depressed than those who felt rested during waking hours. Even after various risk factors were taken into account, the link between the two held up.
At the beginning of the assessment, none of the men entering the study were diagnosed with severe obstructive sleep apnea, but after joining, 856 of them were examined in the light of symptoms related to the condition.
