So you want to use your computer or phone before (or in!) bed - but don’t want your sleep to suffer?
You see, when your eyes receive blue, purple, or white light, your brain is triggered to wake up.
The sky is blue.
So it must be daytime.
And you should wake up.
Or so your brain thinks.
As previously blogged, melatonin is a hormone that promotes sleep.
Due to the aforementioned effects on melatonin release, these colours – and the screens displaying them - make you feel stimulated, invigorated, and awake!
Which is great … when you want to work.
Not quite so wonderful when you’re prepping for bed.
Fortunately, warmer tones don’t have the same stimulatory effect.
Either program adjusts your display to the time of day.
Warm, relaxing, sleep-promoting tones at night.
Bright, stimulatory, invigorating ones during the day.
So avoid blue, purple, & white.
And, come to think of it ...
... due to my (ahem) proclivity for purple …
... you’re probably better off avoiding this website any time after dusk as well!
(... sigh ... another terrible business model ... ;) )
