Episode notes

Choosing the right type of light bulb, favoring orange or yellow spectrum over bright blue LEDs for evening use, has a significant impact on health. Using dimmer switches instead of flip switches can help adjust lighting levels throughout the day, benefiting mental health and improving sleep quality. Manipulating lighting for health, known as light therapeutics, is a groundbreaking discovery. Bright light in the daytime is beneficial for mental health, while dimming down or changing the color of light in the evening promotes better sleep and brain health. The profound impact of lighting research on human health highlights the importance of considering lighting's effects on health throughout history.
