I use a sleep app that monitors my sleep, because I haven’t been sleeping well. One of the things it said was that 7 minutes of blue light from sceens activates your brain for an hour.
My son said, “then your brain has been activate for the next 40 years.” LOL
But I have taken some steps. I set both my phone and computers to switch to warmer colors (less blue light) in the evenings.
I turned on a setting on my phone that restricts apps at night. You can still access them but you have to override it and it will prompt you for a reminder in 15 minutes. It’s helping me be more conscious of “do I really want to look at that app, since it’s night time.”
I also have started turning my lights down at night. I have smart lights in the living room and master bedroom. and I can tell it to lower the lights to 40%.
And I bought some cheap blue light blocking reading glasses off the internet.
that sleep ap- will it detect stuff like sleep apnea and record how many times a person wakes? and stuff like oxygen levels?
