Mental Strain Tied to Negative Feelings

Recent studies have revealed that mental demand is linked with stress and other forms of affective loss, underlining the importance of implementing positive incentive and task design.


United States: People who evoke the cliché hand-on-forehead gesture and say that a difficult problem is giving them a headache are not exaggerating, a new meta-analysis reveals, as reported by HealthDay.

Researchers said in a study published Aug. 5 in Psychological Bulletin that mental effort seems to cause negative emotions in many contexts.

Indeed, increased mental effort was associated with feelings of frustration, irritation, stress, or annoyance, data revealed.

Key Findings from the Research

“Our findings show that mental effort feels unpleasant across a wide variations of populations and tasks,” said senior researcher Erik Bijleveld, an associate professor of psychology with Radboud University in the Netherlands.

Implications for Professionals

“This is important for professionals, such as engineers and educators, to keep in mind when designing tasks, tools, interfaces, apps, materials or instructions,” Bijleveld added in a university news release. “When people are required to exert substantial mental effort, you need to make sure to support or reward them for their effort.” 

For the review, the authors looked at 170 articles that were posted between 2019 and 2020, encompassing 4,670 participants.

Various people participated in the study, such as healthcare professionals, military personnel, athletic/non-athletic individuals, and college students. They represented 29 countries.

The studies included over 350 various cognitive exercises, ranging from using a new device and being lost in a new environment to rehearsing a golf stroke or participating in a virtual reality simulation.

The results found from both experiments indicate that human mental work can lead to uncomfortable feelings, according to the researchers.

Global Perspectives on Mental Effort

However, the relationship between intensive mental effort and perceived positive or negative affect depends on regions and was less expressed in Asian countries than in Europe or North America, as the rate of studied individuals showed.

This may mean that learning history could be a possible antecedent for mental exertion, meaning that how it affects a person depends on the learning history, researchers added.

High school students in Asia spend more time in academics than students in Europe or North America, and so they pointed out that Asians might have preconditioned themselves to bear more mentally tough work at an earlier age.

Another point that researchers have found rather fascinating is that while mentally demanding activities are not always enjoyable, people pursue them anyway.

“For example, why do millions of people play chess?” Bijleveld said. “People may learn that exerting mental effort in some specific activities is likely to lead to reward. If the benefits of chess outweigh the costs, people may choose to play chess and even self-report that they enjoy chess.”

“Yet, when people choose to pursue mentally effortful activities, this should not be taken as an indication that they enjoy mental effort, per se,” he added. “Perhaps people choose mentally effortful activities despite the effort, not because of it.”

Managers and teachers should bear this in mind whenever they are urging others to get down to business on challenging assignments, as said Bijleveld, as reported by HealthDay.

“On the surface, this seems to work well: Employees and students often opt for mentally challenging activities,” Bijleveld said. “From this, you may be tempted to conclude that employees and students tend to enjoy thinking hard. Our results suggest that this conclusion would be false: In general, people dislike mental effort.”

Every U.S. Rice Sample Tested Shows Arsenic, Cadmium, or Lead 

Be smart about the rice you consume and how you prepare it to reduce your loved ones’ intake of potentially dangerous heavy metals. 

United States: A new study by Healthy Babies, Bright Futures has uncovered that many rice brands sold in U.S. supermarkets—especially in cities like New York and Miami—contain measurable and potentially dangerous levels of heavy metals. Every single rice sample tested had detectable arsenic, with one-quarter exceeding FDA limits set for infant rice cereal, as reported by HealthDay. 

Infant Rules Don’t Apply to All 

Although the FDA implemented a maximum arsenic level for infant rice cereal in 2021, no such rule exists for regular rice consumed by millions—including toddlers and young children. Researchers stress this loophole as a public health concern. 

Major Brands, Major Findings 

The report tested rice from 145 brands including Trader Joe’s, Ben’s, and Goya. Results showed heavy metal concentrations ranging from 63 to 188 parts per billion (ppb), with some samples reaching as high as 240 ppb. Arsenic was the most commonly found, followed by cadmium. 

Industry Response: Consumers Deserve Reassurance 

The USA Rice Federation acknowledged consumer concerns but insisted current arsenic levels in rice pose no significant public health risk, as reported by HealthDay. 

How to Reduce Your Risk 

The report offers key tips for safer consumption: 

Cook it like pasta: Drown your rice in water (6–10 cups per 1 cup of rice) and let it brew. 

Switch it up: Switch to grains such as quinoa, barley, or couscous, since they contain less heavy metals. 

Pick safer varieties: Look for white rice from California, sushi rice, Thai jasmine, or Basmati rice from India. Stay away from brown rice, Southern-grown white rice and arborio rice imported from Italy (Suggested Alternative: Skip those three varieties as they may contain higher levels of metals).

Houston Wastewater Detected Measles Weeks Before Outbreak, Study Finds 

Early detection and prevention of measles can be done by monitoring for the virus in wastewater. 

United States: Measles virus showed up in Houston’s sewage water several weeks before the big measles outbreak happened in Texas in January, according to a new study. 

Early Warning Signs in Wastewater 

Wastewater samples taken on Jan. 7 were found to have measles virus DNA in them, which was reported by scientists in the American Journal of Public Health, as reported by HealthDay. 

According to the researchers, the City of Houston Health Department found and reported two cases of measles in adults not vaccinated for the disease on January 17th. The survey is based on people living in the same areas where the water treatment plants supplied water. 

Measles Resurgence in Texas 

In all, 717 people in Texas had measles as of May 13, reported the Texas Department of State Health Services. Two children who have not been vaccinated have died. 

“With lessons learned from the Houston measles detection event, we are now working with our public health partners to gather data on the current measles outbreak in West Texas,” lead researcher Michael Tisza, an assistant professor of molecular virology and microbiology at Baylor College of Medicine in Houston, said in a news release.  

“Our program has been monitoring measles in wastewater from those sites as well, hoping the information can help officials get ahead of this virus,” Tisza said. 

The sampled Houston treatment plans help more than 218,000 people, according to the researchers. 

Researchers found that testing wastewater before an outbreak revealed that these methods can prepare officials for an infectious disease. 

Wastewater Testing: A Promising Public Health Tool 

“Systematically sequencing the genetic material in wastewater reveals dynamic changes in human viruses circulating in a community,” senior researcher Anthony Maresso, chair of molecular virology and microbiology at Baylor, said in a news release. 

“Importantly, analyzing these viral changes in wastewater can improve our understanding of outbreaks and transmission and inform public health preparedness, just as one uses meteorological data to better understand and predict weather patterns to anticipate potentially dangerous conditions,” Maresso said. 

According to the researchers, there had not been any measles viruses found in any of the 821 wastewater samples collected in Houston in the past 31 months. 

“Because no other cases have been reported and the detections occurred in the same area where the travelers resided, it is reasonable to assume that the measles signal detected in wastewater is from the two infected cases, which underscores the high sensitivity of the method,” Maresso said. 

Vaccination Still the Best Defense 

Co-researcher Eric Boerwinkle, dean of the UTHealth Houston School of Public Health, said that “this work underscores the ability of sophisticated wastewater analyses to serve as an early detection system benefitting public health, healthcare, and communities in preventing a measles outbreak in Houston.” 

If they haven’t already, Boerwinkle advised individuals to acquire the measles vaccine, as reported by HealthDay. 

The best way to stop the contagion of measles is the MMR vaccine, since it has already proven to be both safe and effective.

Your Smartphone Might Predict How Well You Recover from Injury 

With more smartphone data, there will be better ways to predict and guide recovery in orthopedics. 

United States: According to a study published on May 9 in the Journal of Bone & Joint Surgery, smartphone data — including step count, walking speed, and gait — can predict how well someone recovers from bone or hip injuries. The findings suggest that mobility patterns before an injury may offer powerful insights into a patient’s post-surgical progress, as reported by HealthDay. 

Data That Speaks Volumes 

The study, led by Dr. Brian Shear at the University of Maryland Medical Center, followed 107 adults who had previously undergone surgery for a broken leg or hip. Using data from participants’ Apple iPhones, researchers analyzed their pre-injury activity levels — specifically, their steps, speed, and gait — and compared it with their recovery progress. 

Patients who were more active before their injury tended to recover faster and return to mobility more easily. “This novel approach has the power to reshape how orthopedic care is delivered,” Dr. Shear explained. 

A New Era of Personalized Rehab 

The study found that patients with higher daily step counts before their injury had better recovery outcomes. Likewise, those with faster walking speeds and consistent gait patterns pre-injury also healed more effectively — highlighting the predictive value of everyday mobility metrics. 

With this knowledge, doctors are able to plan treatments better, detect possible issues in patients’ progress earlier, and give patients more precise timelines for recovery. 

Expanding the Technology’s Use 

Senior researcher Nathan O’Hara, associate professor at the University of Maryland School of Medicine, announced plans to broaden the study’s scope to include other areas of orthopedics like sports medicine, joint replacement, and shoulder or foot surgery, as reported by HealthDay. 

An app is also under development to support this initiative, with multicenter clinical trials expected to begin later this year.
