Sunlight Benefits:Andrew discusses the benefits of getting sunlight throughout the day, including in the late afternoon and evening hours. Sunlight can protect the nervous system against the negative effects of artificial light during critical period three.
Sunlight and Sleep:Andrew explains how the circadian clock is affected by morning and evening oscillators and how getting sunlight in your eyes in the late afternoon and evening signals to the clock that it's evening time and that sleep is coming. He also discusses how the particular wavelengths of light present in morning versus evening affect the brain and neurons, and how they establish a second reference point for optimal sleep.

15. Optimizing Sleep

Optimizing Sleep:Andrew discusses the critical period of late evening and the importance of avoiding bright artificial lights of any color to optimize sleep. He explains how even a small amount of light can disrupt the circadian clock and recommends dimming the lights in your internal environment and placing low lights in the physical environment.
Light at Night:Andrew shares tips on how to use light at night safely. He suggests using as little artificial light as possible and dimming screens. Candlelight and moonlight are ideal, as they have low light intensity. Overhead fluorescent lights are the worst and should be avoided.
Optimize Your Sleep:Andrew explains the importance of avoiding bright artificial lights between 10:00 p.m. and 4:00 a.m. to improve sleep quality. He also recommends using low lights at night and bright artificial lights during the day to optimize sleep-wake cycles. Additionally, viewing evening sunset light can offset some of the negative effects of artificial light at night.
