How can a renovation of your bedroom improve your well-being, sleep and health? Charlie Luxton explores this question in conversation with father of three, Kristoffer, who slept in his living room with his wife until he renovated the loft of his cosy two-bedroom house in Copenhagen. Meanwhile, Professor Kevin Wymelenberg from the University of Oregon explains the surprising impact daylight and fresh air has on our lives – in our bedrooms and beyond.
