Sleeping Environments (image) Toyohashi University of Technology Caption Toyohashi University of Technology researchers conducted an experiment on the nature of sleep in an evacuation shelter environment. This experiment was performed by creating a mock shelter in the university's gymnasium with four of the emergency blankets as well as a standard futon set. The results showed that the low temperature (5°C) inside the gymnasium affected subjects' sleep and body temperature regulation, reducing sleep efficiency by 10% and increasing fatigue.
