Hi I have noticed a remarkable anti anxiety effect immediately from the following.
You may have heard of the healing effect of so called white noise. And I heard Art Bell the radio host say that the random pattern of snow or static on a tv screen is an example of that type of white noise randomness. So I started unhooking the cable or turning the TV to another channel other than the one that allowed my cable (channel 4) to get an example of that pure snow or static to see what it did to me when I stared at it. The static sound was irritating so I turned the sound off while I stared at the screen on static. I made sure the channel I had it on produced pure static (the black dots jumping around on a white screen) without any bleed through of any broadcast and I held my stare on the screen and this is what I experienced:
An immediate profound antianxiety effect, a calmness, a sleepiness that if I wasnt alert could put me to sleep and a feeling of well being, of pleasure all immediate although the sleepiness progressed with time sometimes and none of these responses stopped no matter how long I stared or how many days in a row I did it.
So I looked up the effect of white noise on the internet and it said that it created the theta brainwave state which was the brainwave state of the fetus and which was thought to be a healing brainwave state. It said it was the brainwave state that we had as we dropped off to sleep. It further said that melatonin was created in greater amounts in that brainwave state and that melatonin had its own sleep inducing and health effect too. It also stated that it created endorphins, which are an anti pain chemical in us and also make us feel good.
If I dont want to stare at it because I want to read or watch a TV show or fix dinner etc I have noticed if I just have the snow somewhere in my field of peripheral vision it works about 75% as well for me
So that is my experience.
