The part where they spoke about various populations sleeping for around an hour longer each night in the winter is very interesting to me.

- AdrianB1 7y agoIt is quite logical, the night is much longer and we used to depend on the light cycle. Also many animals hibernate in the winter, we just sleep a bit more, it is an adaptation to environmental conditions: less light, less food, movement in lower temperatures require more energy, sleep conserves energy. In my country we have a bit less than 9 hours of light in December and over 15 hours in June, we continuously adjust for it.
