(160805) -- VANCOUVER, Aug. 5, 2016 (Xinhua) -- Two sleep pods are placed inside the campus library of the British Columbia Institute of Technology (BCIT) in Vancouver, Canada, Aug. 5, 2016. The institute launched a pilot program by installing barrel shaped, futuristic-looking sleep pods in the campus library. These sleep pods allow students to catch a 30 to 60 minutes power nap between classes in safe and secure surroundings. This pilot program is driven by students' demand and the research indicating that napping helps relieve stress and improve memory. (Xinhua/Liang Sen)
