Winter is also the best time for stews and soups! So there is some benefit from the cold haha.
Oh my, I cannot even begin to imagine the problem of so much sunlight. My body does not shutdown when it is not completely dark. Even with some light coming through the curtains, I am wide awake. I am glad that the night time is increasing, even if only slowly!
Keep well, and I hope that the week is productive and good!
