go dark

A new study by Japanese scientists says that even a small amount of light in the bedroom at night is unhealthy. Their 4-year longitudinal study shows depressive symptoms arise in people with minimal exposure to light.

The March 2018 issue of the American Journal of Epidemiology includes the full report. They note that "exposure to light at night... is the strongest disruptor of circadian physiology and behavior."

A few years ago I started using very dark fabric curtains with opaque lining in my bedroom and was astonished at how dark the room became at night. And I was acutely aware of light at night! I enjoyed somehow the darker quality of my bedroom and I like to think it is better for me.

Less light...
