The Guardian: The newspaper explores how working from bed is disrupting sleep and what can be done to mend these disruptions.

A major consideration is lighting. Even on a dull overcast day in winter it is at least 10 times brighter outside than indoors. Now that we are no longer commuting to work, depriving ourselves of that daylight could have consequences for our sleep and daytime alertness.

Exposure to bright daylight helps to keep our body clocks synchronised with the time of day outside. Without it, these clocks can drift – particularly if we’re exposed to bright light during the evenings – meaning we feel sleepy later. One study found that on average, office workers who were exposed to more daylight – especially during the mornings – took 18 minutes to fall asleep at night, compared with 45 minutes for those who spent their mornings in dim light. They also slept for an extra 20 minutes, had less disturbed sleep, and reported fewer symptoms of depression.
