I know evolution is governed by chance and it is random but does it make sense to “ruin” sleep if there’s light? I mean normally, outside, you never have pure darkness, there are the moon and stars even at night. In certain zones of the Earth we also have long periods of no sunshine and long periods of only sunshine.
I don’t know if my question is clear enough but I hope so.
Bonus question: are animals subject to the same contribution of light or lack of it to the quality of sleep?
Thank you so much for the detailed response, I really appreciate it. Over the years I’ve looked into this a lot but you’ve given me some really useful new information!
Health care in the UK, especially for lesser known genetic diseases, can be a bit of a lottery… I moved up the country 6 months ago, and within a month had been tested & diagnosed for a generic mutation called FMF (familial Mediterranean fever). My dad / sister both have it but despite nearly a decade of requests I was unable to get a doc to investigate it. So far up here the gp response has been a referral to a website for cognitive behavioural therapy.
I’ll push on though and see if there’s anything more they can investigate. Thanks again for the info :)
