Reply to comment by Putin_Delenda_Est in Newly-discovered Earth-mass exoplanet — named Wolf 1069 b — may provide durable habitable conditions across a wide area of its dayside by marketrent

Would it affect circadian rhythms...like getting really tired every 8 hours or something?

No, but its day is essentially the same as its year, so the sun wouldn't appear to move in the sky, and the planet has a day side and a night side and the lack of light changing would be a tiny irritation. But if you colonized it you'd sleep indoors anyway and artificial lighting would provide a normal sleep cycle.

I have always wondered about planets that rotate slower or faster and if that would affect things like sleeping and aging etc. I suppose your body gets tired after x hours of waking so yes artificial lighting and black-out curtains could help, but in place very far north, it's well known that we simply don't do well in limited day or night environments. Still would be interesting to see if we ever get to be interplanary!
