I hadn’t paid much attention to the sleep for a long time; it had been a long time that I had thought that a five-hour quality sleep was adequate for me. However, I begin to realize that a seven or eight hours of good sleep is actually quite important in the pursuit of a quality life. I begin to learn about sleep, insomnia, sleep apnea and hypersomnia. My learning starts from this quoted article “Sleep and depression are related — here’s the surprising reasons why” by Dan Taylor on September 24, 2015 on this web page http://www.morningticker.com/2015/09/sleep-and-depression-are-related-heres-the-surprising-reasons-why/
. We often underestimate just how important sleep is to our health. Many try to fit as many awake hours into the day as possible, leaving just a few hours for sleep rather than getting the recommended eight hours that scientists believe the body needs to completely recover and recuperate. And it’s not just the body that needs to rest: the brain also needs sleep in order to function properly, and when it doesn’t get that adequate sleep because of sleep apnea, it begins to affect one’s psyche.
The study [a study published in the Journal of Clinical Sleep Medicine] helps illustrate just how closely intertwined sleep apnea and depression are. People with depression usually suffer from either one end of the extreme or the other: i.e., they are either insomniacs who find it impossible to get to sleep or their are hypersomniacs, who can’t seem to get enough sleep and will spend the day lying in bed. And people can suffer from both; research has found that people who suffer from both hypersomniac and insomnia are more likely to have severe and longer-lasting depression.
. Unlike most feelings of sadness which fade, depression is a persistent sadness that is often accompanied by anxiety and general hopelessness about life and disinterest in things that the person once enjoyed.
. That’s why this recent study on sleep apnea is so important: it indicates that there may be a strong relationship between sleep and depression. In fact, there seems to be a cyclical relationship between the two, as depression can often interfere with consistent, restful sleep while lack of sleep can enhance depressive disorders. Also, some people don’t have a problem with sleep until they come down with depression, but for others, it was the sleep problems that came first.
. Obstructive sleep apnea is characterized by airways that become constricted during deep sleep. It can result in a stoppage of breathing for a few seconds to a few minutes, and then the brain suddenly realizes what is happening and wakes up the body to resume breathing, interrupting sleep. In OSA sufferers, this by definition happens at least five times per night, preventing them from getting the deep REM sleep they need each night. Those that don’t get enough sleep often wake up feeling fatigued.
. Feelings of hopelessness are one of the most common, as well as a loss of interest in activities that were once interesting. Then there is fatigue and a difficulty in concentrating. The aforementioned problems with sleep, whether insomnia or hypersomnia, are also strong signs.
