Mindsip insights from this episode:
Avoid overhead lighting at night to align with natural rhythms
From an evolutionary perspective, you should avoid overhead lighting at night because the only natural light source that comes from above is the sun, signaling daytime to your body.
Avoid dimming screens to reduce flicker effects
Contrary to intuition, dimming a standard screen actually increases the negative effect of its flicker because the light is in the 'off' phase for a longer percentage of time.
Beware: blue light blockers don't prevent screen flicker harm
While blue light blocking glasses and software like Flux or Iris can reduce blue light, they do absolutely nothing to mitigate the harmful effects of screen flicker.
Avoid screen flicker to alleviate concussion symptoms
The best evidence for the negative impact of screen flicker is that people with concussions or traumatic brain injuries (TBIs) experience migraines and headaches from screens, which are alleviated by using flicker-free reflective displays.
Experience reading on Daylight's innovative reflective tablet
A company called Daylight has developed a tablet with a fast, 60-120fps reflective screen that feels like paper, works in direct sunlight, and has an optional flicker-free, blue-light-free backlight.
Use broad-spectrum orange light for comfortable night reading
For reading on a screen at night, a broad-spectrum orange light is superior to pure red because our eyes are more sensitive to it, requiring less intensity and reducing eye strain.
Utilize black-and-white reflective screens to combat digital addiction
Using a black-and-white reflective screen can reduce digital addiction by acting as less of a 'supernormal stimulus' at a hardware level, unlike vibrant, light-emitting screens.
Utilize 'Reduce White Point' to manage screen light exposure
In your phone's accessibility settings, you can use the 'Reduce White Point' feature to lower the intensity of whites on your screen, which is another tool to manage light exposure.
