@nontoxicdad: Incandescent > LED 💡 LEDs save energy… but at what cost? Flickering your eyes can’t see. Blue-heavy light your body reads as daytime. For most of human history, light had a rhythm: Bright mornings. Full-spectrum midday sun. Warm firelight at night. That rhythm told your body when to wake, focus, and wind down. Now we flood our homes with artificial light long after sunset…and call it normal. Incandescent bulbs give off a continuous, warm spectrum rich in red and infrared wavelengths — closer to the light your body needs at night to wind down. Your body doesn’t care about efficiency. It responds to light.
