As a result, there is still more research to be done if a conclusive link between sleep and heart disease is to be drawn, a link which couldn’t have been drawn through research of this type.
Why?
Doctor Nambiema’s research was an observational study, this means that it could only observe if there was a connection between sleep and heart disease. The only type of study which can do so is a causational study, one which says “X can have an impact on Y” or, in this case, whether sleep can have an impact on heart disease risk.
Nevertheless, this does not make the research worthless as it adds to the gamut of data which shows the benefits of getting an optimal amount of sleep.
Furthermore, if the results of the study are correct then around 90 percent of people could be increasing their risk of heart disease and strokes.
