A group of researchers took part in a study to figure out if rocking while sleeping helps make for a better night of sleep. Eighteen participants in their 20s were randomly selected to perform in this study. They were asked to take part in a night of stationary sleep and a night of continuous rocking with very similar environments. The study observed changes in the sleep patterns such as spindles and how quickly they were able to transition into each stage of sleep. The study found that the rocking at a 0.42hz increased the time in the deepest part of sleep and also helped with their memory. The participants were asked to complete a memory test before they fell asleep and again after they woke up. They were also asked complete a questionnaire about their sleep quality for that night. Most people will believe that having just a small little motion during their sleep will have practically no impact. The participants thought so as well until after the night of rocking. After spending a night in a stationary bed and a night in the rocking bed, the participants said they thought being in the rocking bed was one of the best nights of sleep they ever had.
By being rocked in your sleep, you will have few micro arousals. These small arousals disrupt continuous sleep and force the brain to break away from sleep even if it is just for a brief moment. Arousal density was 60% lower during the deepest part of sleep on the rocking night compared to the stationary night. These disruptions are able to add up over the whole night which disturbs your sleep cycle. The rocking also helped contribute to a shorter time transitioning into the different stages of the sleep cycle. It takes about six minutes less overall to transition into the deeper sleep while on the rocking bed. The rocking also contributed to an increase in sleep spindles. These spindles represent a particular type of brain wave that occurs during sleep, specifically during stage two of the sleep cycle. This difference between stationary and rocking may appear to be small, but this can occur multiple times a night making for a better night of sleep. Most participants woke up after the night of rocking and performed better on the written memory test than they did after the stationary night.
Reflection
While writing this blog post, I felt that it was considerably more difficult trying to translate the research document into a more suitable form for the general public. I thought that it was hard to not write every little detail about the research that I could. I did not write about all the values of everything they found in their data. At first I thought this was very needed information for a research article, but now I find it pretty irrelevant when trying to explain a whole research study to a general audience. If I had included these values all over my post, I think that the reader would have gotten lost very quickly and not have known what I was talking about. I kept in mind the five critical questions about a research study while I wrote this post. My thoughts about authors writing about research studies has changed after having to write one myself. I have more empathy towards them now then when I first read the article. Having to read through the study and trying to understand everything they were talking about was hard enough. Having to translate it into simpler terms was even harder. The most difficult part was trying to pick out the most relevant information about the study without it being too specific. Trying to keep it simple and understandable was a challenging, but if I did not, then the audience would lose interest in reading the rest of the article very quickly. When I first read through the article and critiqued on it earlier in the year, I felt that the article was lacking in a lot of crucial data. I was questioning the authenticity of the whole article and was wondering where all the actual data was. By not including any values, it makes it easier to understand and easier to get hooked into the article. Most, if not all journalists, have to stick to a specific format and have only a small space to work with when writing any type of article. After reading through the source material though, I discovered that the author had to make a lot of tough choices and be very concise on what words they used for the article. Understanding what journalists have to deal with on a daily basis will be very helpful when reading articles in the future. I will think more about the study that they are writing about and look for the five critical questions of a study.
