Daytime Naps and Brain Function: Reviewing Sleep Research

~4 min read

Abstract

This paper critically evaluates Dr. David Jockers' article "Daytime Naps Improve Performance," published on NaturalNews.com, which summarizes findings from sleep studies by researchers at Brock University, Harvard Medical School, and Stanford University. The review examines how effectively Jockers communicates the physiological benefits of napping to a general audience. While the article offers an accessible overview of sleep research, the critique finds that Jockers provides only surface-level commentary, omits key study parameters, and shifts focus inconsistently between daytime napping and general sleep. The paper concludes that although Jockers makes a broadly agreeable point, the article lacks the depth, specificity, and focus necessary to fully inform readers on the physiological advantages of napping.

What makes this paper effective

The paper maintains a clear critical voice throughout, consistently weighing what the source article does against what it fails to do for its intended audience.
Specific textual evidence from the reviewed article is cited at multiple points, grounding each critique in the actual content rather than general impressions.
The critique is balanced — acknowledging that Jockers' article is serviceable for general readers while systematically identifying its analytical shortcomings.

Key academic technique demonstrated

This paper demonstrates article critique writing, a common undergraduate exercise in which students evaluate a published piece for argumentative strength, use of evidence, audience appropriateness, and internal consistency. The author applies a consistent evaluative lens — asking whether the source article substantiates its claims — and uses counterexamples drawn directly from the text to support each critical point.

Structure breakdown

The paper opens with an objective summary of Jockers' article and its three main research references, establishing a baseline before critique begins. It then transitions into progressively sharper evaluation: first addressing the overall shallowness of analysis, then examining misleading framing in the title, and finally identifying the pattern of unsupported generalizations. The single reference concludes the paper in standard APA format.

Introduction to the Article Under Review

Numerous studies have been conducted and articles written to analyze the physiological benefits of sleep. The recent article "Daytime Naps Improve Performance" by Dr. David Jockers focuses on the benefits of daytime sleep and how it affects physical and mental performance (2011). Published by NaturalNews.com, Jockers briefly summarizes the findings of sleep studies performed by three researchers from various institutions. Jockers first mentions a study performed by Dr. Milner at Brock University and notes how participants following naps "were shown to be significantly more physiologically alert" (2011). The article then focuses on Dr. Czeisler of the Division of Sleep Medicine at Harvard Medical School. Dr. Czeisler advises that nap sleep is particularly beneficial for athletes, and he conducted sleep studies on mice to support his notion that nap sleep helps to consolidate memory (Jockers, 2011). Jockers then refers to a series of studies directed by Mah at Stanford University, in which athletes with differing sleep behaviors were examined for physical, mental, and emotional performance. Jockers concludes his article by reinforcing the positive aspects of sleep, advising that naps help one recover from "sleep debt," and recommending an optimal napping period of 10 to 30 minutes (2011).

Summary of Jockers' Key Claims and Sources

Jockers provides a serviceable article for readers with very little previous knowledge of napping benefits and physiological outcomes. The article seems to be intended for a large, general audience, and its oversimplification weakens its intention to educate readers on the physiological advantages of napping. Although Jockers refers to three major sleep studies, he offers only surface commentary and little in-depth analysis. For example, the entirety of Dr. Milner's study is distilled into three sentences, with the central argument highlighted as Jockers stated that "subjects had improvements in subjective sleepiness, fatigue and accuracy on tests of mental sharpness" (Jockers, 2011). There is no indication of how many subjects were tested, how they were tested, the duration of the study, or how results were obtained.

Jockers devotes the most attention in his article to the studies conducted by Mah. Mah studied the sleep patterns of athletes — swimmers, tennis players, and basketball players — who had up to 10 hours of sleep per day, and Jockers reported that all of the athletes showed improved athletic performance within their sport (2011). Jockers did not provide further specifics of the study parameters, but did include the accuracy percentage by which the basketball players' three-point shots improved (2011).

Conclusion: Strengths and Shortcomings of the Article

Jockers aims to provide the reader with an abundance of information within a minimal word count, and by doing so, he makes an easily understood point — but his execution lacks focus and detail.
