Insomnia, which is the inability to go to or stay asleep, was believed to be caused by psychological reasons such as stress or anxiety, Express reported.
A new research study found that information may not be accurate as they concluded that the cause of insomnia might be genetic. The study found that there are seven risk genes for insomnia.
Before this study, most doctors believed that the primary cause of insomnia was depression, anxiety, or stress.
The research found that those that have Periodic Limb Movements of Sleep (PLMS) or Restless Legs Syndrome (RLS) may be predisposed for insomnia. However, the research found that just having one of these conditions does not guarantee that you will suffer from insomnia.
While they found that genetics played a role in insomnia, anxiety and stress still is a significant risk factor. Those with anxiety disorders, depression, neuroticism or stressful living environment often suffer from trouble sleeping.
According to a neuroscientist named Anke Hammerschleg, the reason is those characteristics (psychological conditions) tend to go hand in hand with insomnia.
The research study gives an answer to those who suffer from insomnia and cannot understand why they cannot fall asleep. As it turns out, it really isn’t their fault —it could be genetic.
The research study also found that women tend to suffer more often than men. Of those participants that were older than 50-years-old, 33 percent of the women complained about insomnia whereas only 24 percent of the males noted episodes of trouble sleeping.
The study found that sleeping between six and a half to seven hours is the healthiest and may lead to living a longer life. Also, working overnight could put you at risk for cancer, diabetes, and other life-threatening illnesses.
If you discover you cannot sleep and it becomes troublesome, the experts suggest seeing your doctor because there could be a medical reason that you cannot sleep, particularly if insomnia started suddenly. Acid reflux, Parkinson’s disease, cancer, and kidney disease can cause insomnia.
