Working Near a Window, and Sleeping Better for It
Office workers with windows received far more daytime light, slept almost an hour longer at night and reported better vitality than those without.

This study compared office workers who sat near windows with colleagues in windowless spaces, using wearable trackers alongside health and sleep questionnaires. Those with daylight at their desks received far more bright light during the day and, tellingly, slept on average around three-quarters of an hour longer each night. They also reported better vitality and fewer physical limitations, while the windowless group scored worse on overall sleep quality. The thread running through it is light: daytime light is the main signal that sets the body clock, and a body clock kept in good time sleeps better and feels more alive. It is a small pilot study and the two groups differed in other ways too, so it invites rather than closes the case. Still, it draws a clean line from a feature of a room to the quality of a night's sleep. For a woman weighing where to place her desk, it makes a quietly practical point: get yourself to the light during the day, and the night tends to look after itself.
