Especially relevant, the National Institutes of Health, describe insomnia as a common sleep disorder in which people have a hard time sleeping. Furthermore, insomnia is classified as either transient insomnia, acute insomnia, or chronic insomnia. In fact, the primary differentiator between these three classifications, is the length of time people suffer from insomnia. Above all, transient insomnia usually lasts less than a week, acute insomnia lasts a few weeks, while chronic insomnia lasts several months or years.
Most noteworthy, the three stages of chronic, acute, or transient insomnia correspond to the onset of sleep, maintenance of sleep, and end of sleep.
For example, some people have a hard time going to sleep. But, after falling asleep, they may not be able to stay asleep. Or, after falling asleep they wake up too early in the morning. Or, after falling asleep they stay asleep a long time. On the other hand, some people fall asleep right away but, then, they wake up soon after and have difficulty going back to sleep.
In fact, difficulty falling asleep, sometimes for hours, occurs at the onset of sleep. And, this difficulty may be due to:
Most noteworthy, everyone wakes up at least once in the middle of the night. And most people go right back to sleep, some without even knowing they woke up. But for others, going back to sleep becomes a problem. Indeed, these difficulties may be due to:
Finally, there are times you wake up too early in the morning and can’t go back to sleep. And, this may be due to:
Most of all, transient insomnia is a temporary form of insomnia which can last from one night to a week. Furthermore, transient insomnia may be one night of poor sleep or recurring episodes of insomnia interspersed with days and weeks of normal sleep. Indeed, transient insomnia is caused by the following conditions.
On the other hand, acute insomnia can last several weeks and caused by the following conditions.
Lastly, chronic insomnia lasts a long time, may be even months or years. And, chronic insomnia may occur for the reasons listed below.
Meanwhile, at some point in their lifetime, most people have difficulty falling asleep once in a while. However, it’s only when this problem occurs frequently or regularly that people are diagnosed as having chronic, acute, or transient insomnia.
In fact, studies show that up to 95 percent of Americans suffer from episodes of insomnia as some point in their lives. Furthermore, according to the American Sleep Association, 30 percent of adults experience either transient or acute insomnia, while 10 percent experience chronic insomnia. Especially relevant, 770 million people around the world suffer from chronic insomnia.
Most noteworthy, a February 2019 study, in Nature Genetics, of more than 450,000 people in the United Kingdom identified 57 gene regions associated with chronic, acute, or transient insomnia. Meanwhile, 29 percent of the study participants reported frequent sleeplessness. Furthermore, these gene regions explain why some people get insomnia and other don’t. In addition, the study found that increased insomnia symptoms doubled the risk of coronary artery disease, depression, and a reduced sense of well-being.
Yet, another new study, using DNA from 1.3 million people, resulted in identification of 956 genes. In fact, variants of these genes increased risk of insomnia. Also, the study discovered biological processes, cell types, and areas of the brain that have these genes.
Next, they found that parts of these genes play an important role in the functionality of axons (which allow neurons to communicate with each other). In addition, some of the genes were active in cells of the frontal cortex and the brain’s subcortical nuclei. Especially relevant, recent brain imaging studies showed these same brain areas as suspects in people with insomnia.
Also, the study found a strong genetic similarity between insomnia and:
Finally, the study reported that vulnerability to insomnia runs in families.
Because insomnia doubles the risk of coronary heart disease along with links to other conditions, insomnia needs to be treated. Moreover, treatments for acute or transient insomnia are given in the section below.
Most of all, if none of these remedies work, it is important to see your doctor.
