Worry about light in general.
I'll come on to that because that's the second.
But Michael Gradazar, as I was saying, what he found is that the blue light doesn't really disrupt your sleep.
It's a combination of first, these devices that we use are attention capture devices.
and they are designed to fleece you of your attention economy, and they do it ruthlessly well.
They've spent tens of millions of dollars designing these products to do that.
So what happens is that these devices become hugely activating.
And as a result, they essentially will be a mute button on your sleepiness.
So you could be there.
You get into bed.
It's 11 p.m.
You think, I am so tired.
I was falling asleep on the couch watching television.
And then you get into bed.
You start going on to social media.
And then you start doom scrolling.
And then you get into this what we call bed rotting where you just sit there.
And now you look at the clock.
And it's no longer 11 p.m., it's 1 a.m., and you've just done sleep procrastination.
Now, it turns out that it's, yes, that, that these are attention-grabbing devices that will mute your sleepiness, but you have to be of a certain personality type, he found.
