Research Supports Health Benefits For Daytime Light Exposure

Bright light exposure during the day has been linked with better sleep and mood. For example, office workers who have more natural light from windows in their work environments have higher quality sleep and fall asleep faster than those without well-lit offices. They also reported lower symptoms of depression than office workers without high levels of light exposure. Specifically, the individuals with natural light are more likely to:

• Experience higher sleep continuity throughout the night
• Take less time to fall asleep
• Report lower levels of negative emotions
