Mindsip insights from this episode:

Utilize light angle to enhance biological rhythms

Light from above sends a stronger daytime signal to your brain because the cells that detect circadian light (IPRGCs) are most dense in the lower half of your retina.

Switch between light modes effortlessly with full-spectrum bulbs

Special full-spectrum bulbs can switch between daytime, twilight, and nighttime modes simply by flicking a standard light switch on and off within three seconds.

Recognize skin's role in detecting blue light for circadian health

Your skin contains melanopsin receptors that can detect blue light, which has an influence on your circadian clock separate from your eyes.

Wear blue light blocking glasses at night despite software use

Even when using software like Iris or Flux, screens still produce 'LED backlight bleed,' so it's best to still wear proper blue light blocking glasses at night.

Choose effective blue light glasses to protect your eyes

Around 95% of blue light blocking glasses are considered ineffective because they don't block the correct light frequencies specified by scientific literature.

Mitigate EMFs from conventional light bulbs with constant current drivers

Most conventional light bulbs produce three types of EMFs: dirty electricity, electric fields, and magnetic fields, which can be mitigated by bulbs using a constant current driver.

Incorporate incandescent bulbs to enhance infrared light in your space

Since modern LEDs lack infrared light, you can better mimic the full solar spectrum by adding traditional incandescent bulbs to a room alongside your full-spectrum LEDs.
