Sleep and Indoor Air Quality

Aging populations are a world-wide concern. The Chinese demographic statistics announced in March 2021 showed that the percentage of the population 60 years old or more in China was 18.7% (260 million). People experience many physiological and psychological changes in old age, including a decrease in sleep quality and quantity and altered sleep structure. 1 Sleep disturbance of about 50% has been observed among the elderly in many countries.

Objectives: This project investigated into the design and construction of an isolation pod to keep infected people in quarantine, thus avoiding the spread of viruses such as the COVID-19. This product was made to be used in hospitals and at homes. Background: Mauritius is among the few countries, which has not had any cases of COVID-19 since for since May 2020 for a period of 150 days. It has opened its borders since October 2020, and since Mauritius being a small country, the spread of any type of virus can be imminent if not controlled properly. In case there is another spread of the COVID-19 in Mauritius, then the isolation pod could be used to keep infected people in quarantine. The aims of the study were to develop a prototype of an isolation cubicle that is collapsible and can be easily erected at homes or in hospitals, whenever the need arises. Methods: A prototype of the pod was made with metal bars welded together and tarpaulin materials were sewn together. A HEPA Fan Extractor was fitted inside the pod to allow the air to circulate. Results: the tests carried out the pod could easily be assembled, transported and stored for further usage. From the volunteers’ feedback, it was found that the pod was comfortable, spacious, and practical. The air monitoring tests carried on the carbon dioxide, temperature, and relative humidity were within the acceptable ranges.
