A lot of people in the world are addressing the problem of insomnia. However much of them attribute this to lifestyle but as far as scientific explanation, most attribute it to food consumption or psychological issues that affect us when we are thinking too much.

Gamma-aminobutyric acid (GABA), the most common inhibitory transmitter in the brain, has been identified as severely reduced in people suffering with primary insomnia. Primary insomnia is a manifestation of a neurobiological state of hyperarousal, which is present during both waking and sleep at physiological and cognitive levels.

So as far as insomnia is concerned, we can see that it is a lot more serious than just not being able to sleep. Much of our nervous system components are bound to be affected so it would be best to address it and see a sleep specialist to find some cures for it.
