It’s midnight in the north of Sweden, just below the Arctic Circle, and I can’t fall asleep. It’s not because I’m anxious or had one too many cups of coffee (which is often the case) but because the sun never sets! Most homes and hotels have blackout blinds or curtains, but my current home, a tent, doesn’t. I decided, after a few restless nights, that I should buy a sleep mask. In the end, I have to admit, camping in the beautiful nature that surrounds me is well worth the lackluster quality of sleep I’ve had.
