Last week, I decided to change up my nightly routine. Instead of climbing into bed with my iPad and checking social media/tech news before going to sleep, I decided to switch to reading a book on my Kindle and then, as of last night, switching to my Kobo Libra instead (I prefer the Libra, as it has page turn buttons and understands that some people are left-handed, but the first book I read was a Kindle exclusive [boo]).
I use my Garmin Forerunner 255 to track my sleep and while it is not going to be 100% accurate, it usually gets pretty close to reflecting how I feel I’ve slept. It gives your sleep a score between 1-100.
Except for one bad night’s sleep (late to bed, stressed, early to rise), my scores have been consistently in the mid 70s to mid 80s, with plenty of REM sleep. During the blue light/iPad phase in the weeks before, my scores would dip into the 30s and 40s and insufficient REM sleep was a common issue.
So yes, it appears removing blue light as I was getting ready to sleep has resulted in better sleep. Science!
It also means I’ve finished reading an entire book this year. Miracle!
