And then all of your hormonal patterns, which happen on a circadian rhythm, can sort of
uh, happen in concert with that.
That's really important.
And then, you know, in the middle of the day, getting out in the middle of the day, spending some time in the middle of the day on bright sunlight, even without glasses or sunglasses, you don't have to look at the sun again, you don't have to hurt your eyes, but getting these cues from our light environment are important.
And then at night,
having an absence of light is really important there are good studies showing that the brighter our days and the darker our nights the longer we live and the reverse is true there are negative impacts on longevity when your days are dark and gray presumably you're inside not we're not not talking seattle here because even outdoors in seattle in the winter it's brighter than it is indoors
And if your nights are sort of not dark enough, these, this coordination of just always gray and never bright and dark, this is bad for our longevity as humans.
And we don't think about this, but I mean, back to where we've come from as humans, bright days outside and the nights are super dark, even a full moon.
Oh, Wi-Fi is interesting.
So again, this gets fairly technical, but the signal that your cell phone puts out, the signal that your Wi-Fi router puts out, these are in the radio frequency EMF band.
And there's conflicting research here.
We're not sure as humans, but I take this, I'm cautious with this.
And so in most of the time in my house, there's no Wi-Fi, which means I use cords.
It's not very pretty, but if I can, I've sort of built the ethernet cables into the walls and I'll use ethernet.
So I don't have Wi-Fi in the house.
during the day.
So if you use an RF EMF meter, a radio frequency EMF meter in my house, it's essentially going to say zero, unless there's a cell phone around.
Now, at night, especially, I think, why not just turn the Wi-Fi off?
I'm not surfing the internet at two in the morning when I'm in dreamland.
I don't need Wi-Fi in my house.
