Reuters reports on a recent study in Sleep Health that found a connection between morning light and better sleep. 

To see whether typical office workers get enough light to regulate their sleep-wake cycle, the study team recruited participants in five government office buildings across the United States.

A total of 109 employees working at the offices wore light-measuring devices for one week in summertime to gauge their exposure to different types of light throughout the day, and 81 of these participants repeated the experiment in winter as well.

The office workers logged their sleep and wake times and completed questionnaires about their mood and sleep quality at the end of each study period.

Researchers found that people who were exposed to greater amounts of light during the morning hours, between 8 a.m. and Noon, fell asleep more quickly at night and had fewer sleep disturbances during the night compared to those exposed to low light in the morning.
