For all insomniacs who have been struggling to get a good night sleep, there is now quite literally a light at the end of the tunnel.

A team of Swiss, German, and Canadian scientists have just discovered the circuit in the brain that is responsible for sleep and wakefulness.

And more importantly, how to use a “flashlight” to get a full night sleep.

The study was published it in the journal Nature Neuroscience at the end of 2015.

Insomniacs fail to get enough deep sleep. This is the sleep phase during which your brain waves are at their slowest (less than four hertz), and during which you do not dream.

It is the best rest that humans can get.

The neurons that control your brain waves to slow down so you sleep are called GABA neurons. They are placed in your lateral hypothalamus.

If you want to sleep, you want the GABA neurons to be quiet, and if you want to wake up, you want them to be active.

This is precisely what the scientists did to the mice in their study, and what they hope to be able to do to us some day.

They used a new science called optogenetics to enable and disable these GABA neurons. Optogenetics is like a flashlight that controls the behavior of neurons from outside the skull. So no surgery, no invasion.

Other areas where they have applied it shut down the neurons that cause epileptic seizures and cause cocaine dependence, and to re-activate neurons that caused deafness.

Unfortunately, more research is needed for this treatment to be used for human beings. Primarily because optogenetics requires that neurons are fed a light-sensitive protein to make them sensitive to the lights used in the treatment.

But imagine how cool it will be to lie in a hospital for a few minutes while a doctor quiets down your GABA neurons with a flashlight so that you can get a full night’s sleep?

But you’ll probably not need that.

Why?

Because here is a much simpler and safer method, you can use at home, to be fast asleep in just minutes – starting tonight…
