I wonder if it is just because we spend more time sedentary instead of up and moving. I know I sleep awesome if I have an intense day of renovation work or yard work or whatever. I looked for some research and this study has farmers sleeping much better than desk workers: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4363513/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4363513/ This study is interesting as it looks at elderly and finds that opposite. Elderly that were blue collar workers sleep worse than those that were white collar workers. It could be that the blue collar workers are no longer getting as much exercise and sleep crappy - or just that their bodies are screwed up after so many years of hard work. https://pubmed.ncbi.nlm.nih.gov/8796375/ https://pubmed.ncbi.nlm.nih.gov/8796375/
