JO CSTD: I think the two studies are saying something similar, namely that 7 hours sleep a night is the optimum that we should aim for. More or less than that has an impact on your health over the long term.
This similarity is interesting in itself. Julie mentioned that we should not hold up one study to be the truth, that a number of studies have to confirm the findings before we can be more definite. Well that is two showing similar results.
Julie: I would agree with you for the most part, but I would add that the sample size for the study I first quoted was not trivial, over 10,000 individuals. This size would average out most anomalies, but you are right it is just one study and that has to be taken into account.
