We all know the importance of sleep and the consequences of not having enough sleep or low sleep. Tons of researches have been made on the effects of sleep in order to make us aware of how sleep actually changes one’s life. Recently, some new discoveries had been made on the influence of sleep with the blood sugar and the rate of fat.

In this article from society of science, Dr. Josiane makes a research to find the relation between the quality of sleep and the blood sugar. She uses dogs to examine how sleep affect the dogs’ blood sugar rate in both short terms and long terms. She first makes the dogs lack of sleep and uses glucose tolerance test to measure the short term effect of lack of sleep and the blood sugar rate. Then she feeds the dogs with high fat food and does a single blind experiment to those who have higher blood sugar rate. After the data collection, observation and analyzation, Dr. Josiane gets the conclusion that lack of sleep does lead to higher blood sugar rate which may causes diabetes.

Actually, this experiment, although seems well conducted and designed, is an observational single blind research. This means that the result of it may be affected by third variables in great possibility such as the origin health status of each dogs, the emotion state of dogs and so on. Another can be chance. Since the conclusion is mainly based on the observation from the data of the research, even if Dr. Josiane does this research in reverse, the possibility of she to get the same conclusion is pretty low. Although she successfully reject the null hypothesis which is lack of sleep will not affect the blood sugar test, correlation does not equal to conclusion which indicates this relationship between sleep and blood sugar still needs further researches to prove. Moreover, from the last sentence of this article, there exists the possibility that the conclusion is influenced by the drawer problem that the conclusion must be in one way in order to satisfy the public.

In conclusion, if this conclusion is true, teenagers should be aware of their own health status by having enough sleep. However, to get more details of this result, more experiments should be made to prove whether this statement is true or false.
