Working in a windowless office is detrimental to a person’s physical   health and quality of sleep, a study claims.     
Conducted by medical and   architectural experts, the study focuses on the influence of natural light—or   lack thereof—on the health of   office workers. Head author and architect specialist Mohamed Boubekri [muh-ha-MAHD boh-bek-kree] considers   the office as the best place to assess public health, as it is where most   people generally spend most of their day. 
The researchers observed 49   employees, 27 of whom work in offices with windows while the other 22 work in   enclosed workplaces. The study   made use of actigraphy [ak-TIG-RUH-FEE]   and health surveys to collect data on the sleeping habits and physical   energy of the participants.  
Results show that workers in   windowless offices are more physically healthy than those in enclosed   offices. The deciding factor of these findings is daylight exposure. On the   other hand, the windowless group is found to have poor vitality and an average of only 6.5 sleeping hours because they   receive little to no natural light in the workplace. The window group, on the   other hand, show more physical energy and sleep 46 minutes longer as their   offices allow regular exposure to daylight.  
The researchers further stated that insufficient daylight exposure   disrupts the body’s circadian rhythm [sur-KEY-dee-uh n,   -KAD-ee-, sur-kuh-DEE-uh n   RITH -uh m],   often leading to sleeping problems.  
Through their findings, the   researchers call for more attention to the important role of daylight   exposure in public health. Furthermore, they encourage architects and   designers to be more open to the idea of building offices and workplaces with   more windows, ensuring that office workers have adequate exposure to natural   light.
