What Is Idiopathic Insomnia?
Imbalanced Brain Centers
The portion that controls sleep in the brain is known as the sleep center, while the realm that connects to an awake state of consciousness is commonly called the awake center. Patients suffering from idiopathic insomnia have an overload of synapse activity going in in the former and a below-normal threshold of commands in the latter.
There is a constant stream of scientific study that seeks to better understand the causes of chronic insomnia. One of the more intriguing recent findings involves metabolic calorie burning. Researchers at Colorado University-Boulder ascertained that a proper night's sleep translates into 135 calories less of daily required energy. However, it is thought that those who have trouble getting to sleep or remaining asleep may be burning too much calorie energy at night for some reason, and that "furnace" activity is partly what is keeping them awake.
Another less obvious cause of insomnia, chronic and partial, could also be the overall work and home environment in which the sufferer spends their daily, waking hours. Especially if the person in question works in a noisy factory, warehouse or other similar environment.
A study comparing individuals with hearing loss caused by their work with other employees at the same location without that affliction found that there was a clear constant correlation between the 99 hearing impaired study subjects and a higher incidence of insomnia, independent essentially of age. Part of the problem for these people is also definitely the onset of a ringing in their ears, a.k.a. tinnitus.
