The Effect of Artificial Light on the Circadian System
27:50 - 33:35 (05:45)
The circadian system is very sensitive to light, and humans going up North have been exposed to a light environment that is completely changed causing problems. Being exposed to bright light in the day is not going to have negative effects; however, if you put humans in artificial conditions, the way they perceive light and darkness changes.

The circadian system in our brain needs to be synchronized with the outside world to determine where we are in the day-night cycle.
27:50 - 29:24 (01:33)
Summary
The circadian system in our brain needs to be synchronized with the outside world to determine where we are in the day-night cycle. It is responsible for regulating various biological processes and plays a crucial role in maintaining overall health.

Summary
The speaker discusses the impact of human evolution on our ability to handle different levels of light exposure, particularly when venturing further north. They argue that being exposed to bright light during the day is not harmful and that our system can still distinguish between lower and higher light levels.
