Do you notice any difference in the time needed to fall asleep during those days?  Do you also have long nights in the Winter? Do you eat traditional special foods during Winter months?  Can you please share what is a traditional daily Winter/Summer schedule (meals and sleep hours) in your area?  Sorry about all the questions. I greatly admire the traditions and people living in inhospitable environments. Share this post Link to post Share on other sites
