Try this experiment. Turn on your TV, turn out the light, and then sit with your back to it. Also, mute the volume. I did this accidentally tonight and I was surprised by the intensity and variation of the light. Not surprisingly, this is much stronger during commercials. You might not notice it as much if you have lights on and the sound on. Regardless, the TV is stimulating you more than you might imagine. I suspect it is not healthy or relaxing. It would be good if he TV could modulate that for you. Or get some software to do it instead, with the signal going through it before it gets to the screen. Either way, it’s something to be aware of.
