Is a standing desk actually bad for your health?
A new study finds that supposedly healthier standing desks cause physical pain and slow down users’ thinking.
That sound you hear is the pendulum of ergonomic wisdom swinging back toward you — you may want to duck. After taking the business world by storm a few years back as the best thing sedentary office workers can do for their health, a new study asserts that standings desks are, in fact, bad for you. They're also not the promoters of workplace productivity they've been claimed to be. They apparently result not only in physical pain, but — literally adding insult to injury — make you a bit slower mentally.
The study, recently published in the journal Ergonomics, looks at the “short term musculoskeletal and cognitive effects of prolonged standing for office computer work," and what it finds may make you, well, sit down, sitting health be damned. Previous research has looked at the long-term consequences of standing as you work and found it often results in calf swelling due to varicose veins that can lead to hospitalization.
For the new research, researchers studied 20 individuals — 13 female, 7 male — who worked in a standing position for two hours in a laboratory setting. Subjects wore their own flat footwear and were instructed to “stand in their usual manner and were advised to rest their forearms, but not lean on the desk surface."
Prior to the experiment, every 30 minutes, and finally at the end, the subjects completed a custom version of the Nordic Musculoskeletal Questionnaire to report their current physical state. After the two hours, they were asked at that point when they would have chosen to sit down given the choice. The researchers tested subjects' mental states using two tests: the Sustained Attention to Response Test (SART) for reaction time, and the Ruff Figural Fluency Test (RFFT) for higher cognitive function. Finally, their muscle fatigue and mobility were monitored through electromagnetic devices.
19 of the subjects completed the experiment, with one dropping out after 74 minutes due to overwhelming discomfort. On average, they'd all have quit around 80.5 minutes if it had been up to them.
Over time, the study concluded that “discomfort increased in all body areas," while “sustained attention reaction time deteriorated." There is some good news, though: “creative problem solving improved."
The takeaway here is that the only way to stay fit, no matter what kind of work you do, is to exercise. Being sedentary is dangerous, but standing desks are not the solution, and it's also unlikely their cousin the “walking desk" — a standing desk combined with a treadmill — is any healthier. Physiotherapy expert Alan Taylor tells The Telegraph, “The bottom line is that this expansion [in the use of such desks] has been driven more by commercial reasons than scientific evidence." Not to mention trendiness.

Whether or not women think beards are sexy has to do with "moral disgust"
- A new study found that women perceive men with facial hair to be more attractive as well as physically and socially dominant.
- Women tend to associate more masculine faces with physical strength, social assertiveness, and formidability.
- Women who display higher levels of "moral disgust," or feelings of repugnance toward taboo behaviors, are more likely to prefer hairy faces.
Beards and perceptions of masculinity<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjU5OTg0MC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY0NzkxMjM3N30.cH-GqNwP5GVqvstgJWAhBPn1B_lYpVEAI0I7iax7EQw/img.jpg?width=1245&coordinates=0%2C1900%2C0%2C849&height=700" id="caae6" class="rm-shortcode" data-rm-shortcode-id="cb0a355a4e8e1899789bc45f3f7aef56" data-rm-shortcode-name="rebelmouse-image" />
Photo Credit: Wikimedia<p>The study used 919 American (mostly white) women ages 18-70 who rated 30 pictures of men they were shown with various stages of facial hair growth. The photographs depicted men with faces that had been digitally altered to look more feminine or more masculine, with a beard and without a beard. The women rated the men according to perceived attractiveness for long-term and short-term relationships. The study found that the more facial hair the men had, the higher the men were rated on their attractiveness, particularly for their suitability for a long-term relationship.</p><p>Part of this might be attributed to facial masculinity — i.e. protruding brow ridge, wide cheekbones, thick jawline, and deeply set narrow eyes — which conveys information to a woman about a man's underlying health and formidability. Women tend to associate more masculine faces with physical strength and social assertiveness. It can also indicate a man with a superior immune response. The researchers suggested that their findings favoring bearded men could be due to the fact that facial hair enhances the masculine facial features on a man's face, like creating the illusion of a thicker jaw line. This could communicate direct benefits to women like resources and protection that would enhance survival among mothers and their infants. In other words, while a beard doesn't mean superior genetics in and of itself, it might be a primitive, ornamental way of saying, "Hey girl, I'm a testosterone-fueled lean, mean, pathogen fighting machine." <br></p><p>It could also be that a beard becomes its own destiny. The researchers in this study cite prior research that found that by growing a beard, men felt more masculine and had higher levels of serum testosterone, which was linked to a higher level of social dominance. They also tended to subscribe to more old-school beliefs about gender roles in their relationships with women as compared to men with clean-shaven faces.<span></span><br></p>
What does disgust have to do with beard preference?<p>Obviously, not all women dig beards. The researchers were particularly interested in what traits make a women prefer bearded men over clean-shaven faces. They looked into several factors including a woman's disgust levels on various concepts, her desire to become pregnant, and her exposure to facial hair in her personal life. </p><p>According to the study, women who were not into facial hair were turned-off by potential parasites or other critters they imagined could be in the hair or skin. Women ranking high on this "ectoparasite disgust" scale might have viewed beards as a sign of poor grooming habits. However, women who ranked higher in levels of "pathogen" did find the bearded men to be desirable, possibly because they perceived beards as a signal of good health and immune function. An intriguing discovery in the study was links to morality. Women who displayed higher levels of "moral disgust," or feelings of repugnance toward taboo behaviors, were more likely to prefer hairy faces. The authors opined that this could reflect a link between beardedness, politically conservative outlooks, and traditional views regarding performances of masculinity in heterosexual relationships.</p>

They also found that women with bearded husbands found beards to be more attractive, which might indicate that social exposure to beards influences how desirable they are perceived of as being. Or it could be that men with wives who like beards grow beards.</p><p>It's important to note that culture plays a huge role in how attractive women perceive certain male characteristics as being. This study looked at a small, culturally specific group of American women, so no big, universal claims should be made about masculinity, facial hair, and male desirability to women. However, research like this is important in highlighting how human grooming decisions are driven by much more than fashion trends. Sociobiological, economic, and ecological factors all play a part in the way we choose to present ourselves.</p>
