Some companies claim remote work hurts wellbeing. Research shows the opposite.
Many leaders at top companies are trying to get workers to return to the office. They say remote and hybrid work are bad for their employees’ mental well-being and lead to a sense of social isolation, meaninglessness, and lack of work-life boundaries, so we should just all go back to office-centric work.
One example is Google, where the company’s leadership is defending its requirement of mostly in-office work for all staff as necessary to protect social capital, meaning people’s connections to and trust in one another. That’s despite a survey of over 1,000 Google employees showing that two-thirds feel unhappy about being forced to work in the office three days per week. In internal meetings and public letters, many have threatened to leave, and some are already quitting to go to other companies with more flexible options.
Last month, GM rolled out a policy similar to Google’s, but had to backtrack because of intense employee opposition. The same is happening in some places outside of the U.S. For instance, three-fifths of all Chinese employers are refusing to offer permanent remote work options, according to a survey this year from The Paper.
For their claims that remote work hurts well-being, some of these office-centric traditionalists cite a number of prominent articles. For example, Arthur Brooks claimed in an essay that “aggravation from commuting is no match for the misery of loneliness, which can lead to depression, substance abuse, sedentary behavior, and relationship damage, among other ills.” An article in Forbes reported that over two-thirds of employees who work from home at least part of the time had trouble getting away from work at the end of the day. And Fast Company has a piece about how remote work can “exacerbate existing mental health issues” like depression and anxiety.
For his part, author Malcolm Gladwell has also championed a swift return to the office, saying there is a “core psychological truth, which is we want you to have a feeling of belonging and to feel necessary…I know it’s a hassle to come into the office, but if you’re just sitting in your pajamas in your bedroom, is that the work life you want to live?”
These arguments may sound logical to some, but they fly in the face of research and my own experience as a behavioral scientist and as a consultant to Fortune 500 companies. In these roles, I have seen the pitfalls of in-person work, which can be just as problematic, if not more so. Remote work is not without its own challenges, but I have helped 21 companies implement a series of simple steps to address them.
Research finds that remote work is actually better for you
The trouble with the articles described above - and claims by traditionalist business leaders and gurus - stems from a sneaky misdirection. They decry the negative impact of remote and hybrid work for wellbeing. Yet they gloss over the damage to wellbeing caused by the alternative, namely office-centric work.
It’s like comparing remote and hybrid work to a state of leisure. Sure, people would feel less isolated if they could hang out and have a beer with their friends instead of working. They could take care of their existing mental health issues if they could visit a therapist. But that’s not in the cards. What’s in the cards is office-centric work. That means the frustration of a long commute to the office, sitting at your desk in an often-uncomfortable and oppressive open office for at least 8 hours, having a sad desk lunch and unhealthy snacks, sometimes at an insanely expensive cost and, for making it through this series of insults, you’re rewarded with more frustration while commuting back home.
In a 2022 survey, the vast majority of respondents felt that working remotely improved their work-life balance. Much of that improvement stemmed from saving time due to not needing to commute and having a more flexible schedule.
So what happens when we compare apples to apples? That’s when we need to hear from the horse’s mouth: namely, surveys of employees themselves, who experienced both in-office work before the pandemic, and hybrid and remote work after COVID struck.
Consider a 2022 survey by Cisco of 28,000 full-time employees around the globe. Nearly 80 percent of respondents say that remote and hybrid work improved their overall well-being: that applies to 83 percent of Millennials, 82 percent of Gen Z, 76 percent of Gen Z, and 66 percent of Baby Boomers. The vast majority of respondents felt that working remotely improved their work-life balance.
Much of that improvement stemmed from saving time due to not needing to commute and having a more flexible schedule: 90 percent saved 4 to 8 hours or more per week. What did they do with that extra time? The top choice for almost half was spending more time with family, friends and pets, which certainly helped address the problem of isolation from the workplace. Indeed, three-quarters of them report that working from home improved their family relationships, and 51 percent strengthened their friendships. Twenty percent used the freed up hours for self-care.
Of the small number who report their work-life balance has not improved or even worsened, the number one reason is the difficulty of disconnecting from work, but 82 percent report that working from anywhere has made them happier. Over half say that remote work decreased their stress levels.
Other surveys back up Cisco’s findings. For example, a 2022 Future Forum survey compared knowledge workers who worked full-time in the office, in a hybrid modality, and fully remote. It found that full-time in-office workers felt the least satisfied with work-life balance, hybrid workers were in the middle, and fully remote workers felt most satisfied. The same distribution applied to questions about stress and anxiety. A mental health website called Tracking Happiness found in a 2022 survey of over 12,000 workers that fully remote employees report a happiness level about 20 percent greater than office-centric ones. Another survey by CNBC in June found that fully remote workers are more often very satisfied with their jobs than workers who are fully in-person.
Academic peer-reviewed research provides further support. Consider a 2022 study published in the International Journal of Environmental Research and Public Health of bank workers who worked on the same tasks of advising customers either remotely or in-person. It found that fully remote workers experienced higher meaningfulness, self-actualization, happiness, and commitment than in-person workers. Another study, published by the National Bureau of Economic Research, reported that hybrid workers, compared to office-centric ones, experienced higher satisfaction with work and had 35 percent more job retention.
What about the supposed burnout crisis associated with remote work? Indeed, burnout is a concern. A survey by Deloitte finds that 77 percent of workers experienced burnout at their current job. Gallup came up with a slightly lower number of 67 percent in its survey. But guess what? Both of those surveys are from 2018, long before the era of widespread remote work.
By contrast, in a Gallup survey in late 2021, 58 percent of respondents reported less burnout. An April 2021 McKinsey survey found burnout in 54 percent of Americans and 49 percent globally. A September 2021 survey by The Hartford reported 61 percent burnout. Arguably, the increase in full or part-time remote opportunities during the pandemic helped to address feelings of burnout, rather than increasing them. Indeed, that finding aligns with the earlier surveys and peer-reviewed research suggesting remote and hybrid work improves wellbeing.
Remote work isn’t perfect – here’s how to fix its shortcomings
Still, burnout is a real problem for hybrid and remote workers, as it is for in-office workers. Employers need to offer mental health benefits with online options to help employees address these challenges, regardless of where they’re working.
Moreover, while they’re better overall for wellbeing, remote and hybrid work arrangements do have specific disadvantages around work-life separation. To address work-life issues, I advise my clients who I helped make the transition to hybrid and remote work to establish norms and policies that focus on clear expectations and setting boundaries.
For working at home and collaborating with others, there’s sometimes an unhealthy expectation that once you start your workday in your home office chair, and that you’ll work continuously while sitting there.
Some people expect their Slack or Microsoft Teams messages to be answered within an hour, while others check Slack once a day. Some believe email requires a response within three hours, and others feel three days is fine. As a result of such uncertainty and lack of clarity about what’s appropriate, too many people feel uncomfortable disconnecting and not replying to messages or doing work tasks after hours. That might stem from a fear of not meeting their boss’s expectations or not wanting to let their colleagues down.
To solve this problem, companies need to establish and incentivize clear expectations and boundaries. They should develop policies and norms around response times for different channels of communication. They also need to clarify work-life boundaries – for example, the frequency and types of unusual circumstances that will require employees to work outside of regular hours.
Moreover, for working at home and collaborating with others, there’s sometimes an unhealthy expectation that once you start your workday in your home office chair, and that you’ll work continuously while sitting there (except for your lunch break). That’s not how things work in the office, which has physical and mental breaks built in throughout the day. You took 5-10 minutes to walk from one meeting to another, or you went to get your copies from the printer and chatted with a coworker on the way.
Those and similar physical and mental breaks, research shows, decrease burnout, improve productivity, and reduce mistakes. That’s why companies should strongly encourage employees to take at least a 10-minute break every hour during remote work. At least half of those breaks should involve physical activity, such as stretching or walking around, to counteract the dangerous effects of prolonged sitting. Other breaks should be restorative mental activities, such as meditation, brief naps, walking outdoors, or whatever else feels restorative to you.
To facilitate such breaks, my client organizations such as the University of Southern California’s Information Sciences Institute shortened hour-long meetings to 50 minutes and half-hour meetings to 25 minutes, to give everyone – both in-person and remote workers – a mental and physical break and transition time.
Very few people will be reluctant to have shorter meetings. After that works out, move to other aspects of setting boundaries and expectations. Doing so will require helping team members get on the same page and reduce conflicts and tensions. By setting clear expectations, you’ll address the biggest challenge for wellbeing for remote and hybrid work: establishing clear work-life boundaries.
New approach to brain health is sparking memories
What if a few painless electrical zaps to your brain could help you recall names, perform better on Wordle or even ward off dementia?
This is where neuroscientists are going in efforts to stave off age-related memory loss as well as Alzheimer’s disease. Medications have shown limited effectiveness in reversing or managing loss of brain function so far. But new studies suggest that firing up an aging neural network with electrical or magnetic current might keep brains spry as we age.
Welcome to non-invasive brain stimulation (NIBS). No surgery or anesthesia is required. One day, a jolt in the morning with your own battery-operated kit could replace your wake-up coffee.
Scientists believe brain circuits tend to uncouple as we age. Since brain neurons communicate by exchanging electrical impulses with each other, the breakdown of these links and associations could be what causes the “senior moment”—when you can’t remember the name of the movie you just watched.
In 2019, Boston University researchers led by Robert Reinhart, director of the Cognitive and Clinical Neuroscience Laboratory, showed that memory loss in healthy older adults is likely caused by these disconnected brain networks. When Reinhart and his team stimulated two key areas of the brain with mild electrical current, they were able to bring the brains of older adult subjects back into sync — enough so that their ability to remember small differences between two images matched that of much younger subjects for at least 50 minutes after the testing stopped.
Reinhart wowed the neuroscience community once again this fall. His newer study in Nature Neuroscience presented 150 healthy participants, ages 65 to 88, who were able to recall more words on a given list after 20 minutes of low-intensity electrical stimulation sessions over four consecutive days. This amounted to a 50 to 65 percent boost in their recall.
Even Reinhart was surprised to discover the enhanced performance of his subjects lasted a full month when they were tested again later. Those who benefited most were the participants who were the most forgetful at the start.

Reinhart’s subjects only suffered normal age-related memory deficits, but NIBS has great potential to help people with cognitive impairment and dementia, too, says Krista Lanctôt, the Bernick Chair of Geriatric Psychopharmacology at Sunnybrook Health Sciences Center in Toronto. Plus, “it is remarkably safe,” she says.
Lanctôt was the senior author on a meta-analysis of brain stimulation studies published last year on people with mild cognitive impairment or later stages of Alzheimer’s disease. The review concluded that magnetic stimulation to the brain significantly improved the research participants’ neuropsychiatric symptoms, such as apathy and depression. The stimulation also enhanced global cognition, which includes memory, attention, executive function and more.
This is the frontier of neuroscience.
The two main forms of NIBS – and many questions surrounding them
There are two types of NIBS. They differ based on whether electrical or magnetic stimulation is used to create the electric field, the type of device that delivers the electrical current and the strength of the current.
Transcranial Current Brain Stimulation (tES) is an umbrella term for a group of techniques using low-wattage electrical currents to manipulate activity in the brain. The current is delivered to the scalp or forehead via electrodes attached to a nylon elastic cap or rubber headband.
Variations include how the current is delivered—in an alternating pattern or in a constant, direct mode, for instance. Tweaking frequency, potency or target brain area can produce different effects as well. Reinhart’s 2022 study demonstrated that low or high frequencies and alternating currents were uniquely tied to either short-term or long-term memory improvements.
Sessions may be 20 minutes per day over the course of several days or two weeks. “[The subject] may feel a tingling, warming, poking or itching sensation,” says Reinhart, which typically goes away within a minute.
The other main approach to NIBS is Transcranial Magnetic Simulation (TMS). It involves the use of an electromagnetic coil that is held or placed against the forehead or scalp to activate nerve cells in the brain through short pulses. The stimulation is stronger than tES but similar to a magnetic resonance imaging (MRI) scan.
The subject may feel a slight knocking or tapping on the head during a 20-to-60-minute session. Scalp discomfort and headaches are reported by some; in very rare cases, a seizure can occur.
No head-to-head trials have been conducted yet to evaluate the differences and effectiveness between electrical and magnetic current stimulation, notes Lanctôt, who is also a professor of psychiatry and pharmacology at the University of Toronto. Although TMS was approved by the FDA in 2008 to treat major depression, both techniques are considered experimental for the purpose of cognitive enhancement.
“One attractive feature of tES is that it’s inexpensive—one-fifth the price of magnetic stimulation,” Reinhart notes.
Don’t confuse either of these procedures with the horrors of electroconvulsive therapy (ECT) in the 1950s and ‘60s. ECT is a more powerful, riskier procedure used only as a last resort in treating severe mental illness today.
Clinical studies on NIBS remain scarce. Standardized parameters and measures for testing have not been developed. The high heterogeneity among the many existing small NIBS studies makes it difficult to draw general conclusions. Few of the studies have been replicated and inconsistencies abound.
Scientists are still lacking so much fundamental knowledge about the brain and how it works, says Reinhart. “We don’t know how information is represented in the brain or how it’s carried forward in time. It’s more complex than physics.”
Lanctôt’s meta-analysis showed improvements in global cognition from delivering the magnetic form of the stimulation to people with Alzheimer’s, and this finding was replicated inan analysis in the Journal of Prevention of Alzheimer’s Disease this fall. Neither meta-analysis found clear evidence that applying the electrical currents, was helpful for Alzheimer’s subjects, but Lanctôt suggests this might be merely because the sample size for tES was smaller compared to the groups that received TMS.
At the same time, London neuroscientist Marco Sandrini, senior lecturer in psychology at the University of Roehampton, critically reviewed a series of studies on the effects of tES on episodic memory. Often declining with age, episodic memory relates to recalling a person’s own experiences from the past. Sandrini’s review concluded that delivering tES to the prefrontal or temporoparietal cortices of the brain might enhance episodic memory in older adults with Alzheimer’s disease and amnesiac mild cognitive impairment (the predementia phase of Alzheimer’s when people start to have symptoms).
Researchers readily tick off studies needed to explore, clarify and validate existing NIBS data. What is the optimal stimulus session frequency, spacing and duration? How intense should the stimulus be and where should it be targeted for what effect? How might genetics or degree of brain impairment affect responsiveness? Would adjunct medication or cognitive training boost positive results? Could administering the stimulus while someone sleeps expedite memory consolidation?
Using MRI or another brain scan along with computational modeling of the current flow, a clinician could create a treatment that is customized to each person’s brain.
While Sandrini’s review reported improvements induced by tES in the recall or recognition of words and images, there is no evidence it will translate into improvements in daily activities. This is another question that will require more research and testing, Sandrini notes.
Scientists are still lacking so much fundamental knowledge about the brain and how it works, says Reinhart. “We don’t know how information is represented in the brain or how it’s carried forward in time. It’s more complex than physics.”
Where the science is headed
Learning how to apply precision medicine to NIBS is the next focus in advancing this technology, says Shankar Tumati, a post-doctoral fellow working with Lanctôt.
There is great variability in each person’s brain anatomy—the thickness of the skull, the brain’s unique folds, the amount of cerebrospinal fluid. All of these structural differences impact how electrical or magnetic stimulation is distributed in the brain and ultimately the effects.
Using MRI or another brain scan along with computational modeling of the current flow, a clinician could create a treatment that is customized to each person’s brain, from where to put the electrodes to determining the exact dose and duration of stimulation needed to achieve lasting results, Sandrini says.
Above all, most neuroscientists say that largescale research studies over long periods of time are necessary to confirm the safety and durability of this therapy for the purpose of boosting memory. Short of that, there can be no FDA approval or medical regulation for this clinical use.
Lanctôt urges people to seek out clinical NIBS trials in their area if they want to see the science advance. “That is how we’ll find the answers,” she says, predicting it will be 5 to 10 years to develop each additional clinical application of NIBS. Ultimately, she predicts that reigning in Alzheimer’s disease and mild cognitive impairment will require a multi-pronged approach that includes lifestyle and medications, too.
Sandrini believes that scientific efforts should focus on preventing or delaying Alzheimer’s. “We need to start intervention earlier—as soon as people start to complain about forgetting things,” he says. “Changes in the brain start 10 years before [there is a problem]. Once Alzheimer’s develops, it is too late.”
Will religious people reject organ transplants from pigs?
The first successful recipient of a human heart transplant lived 18 days. The first artificial heart recipient lived just over 100.
Their brief post-transplant lives paved the way toward vastly greater successes. Former Vice President Dick Cheney relied on an artificial heart for nearly two years before receiving a human heart transplant. It still beats in his chest more than a decade later.
Organ transplantation recently reached its next phase with David Bennett. He survived for two months after becoming the first recipient of a pig’s heart genetically modified to function in a human body in February. Known as a xenotransplant, the procedure could pave the way for greatly expanding the use of transplanted vital organs to extend human lives.
Clinical trials would have to be held in the U.S. before xenotransplants become widespread; Bennett’s surgery was authorized under a special Food and Drug Administration program that addresses patients with life-threatening medical conditions.
German researchers plan to perform eight pig-to-human heart transplants as part of a clinical trial beginning in 2024. According to an email sent to Leaps.org by three scholars working on the German project, these procedures will focus on one of the reasons David Bennett did not survive longer: A porcine infection from his new heart.
The transplant team will conduct more sensitive testing of the donor organs, “which in all likelihood will be able to detect even low levels of virus in the xenograft,” note the scientists, Katharina Ebner, Jochen Ostheimer and Jochen Sautermeister. They are confident that the risk of infection with a porcine virus in the future will be significantly lower.
Moreover, hearts are not the only genetically modified organs that are being xenotransplanted. A team of surgeons at the University of Alabama at Birmingham successfully transplanted genetically modified pig kidneys into a brain-dead human recipient in September. The kidneys functioned normally for more than three days before the experiment ended. The UAB team is now moving forward with clinical trials focusing on transplanting pig kidneys into human patients.
Some experts believe the momentum for xenotransplantation is building, particularly given the recent successes. “I think there is a strong likelihood this will go mainstream,” says Brendan Parent of NYU Langone Health.
Douglas Anderson, a surgeon who is part of that kidney xenotransplant team, observes that, “organ shortages have been the major issue facing transplantation since its inception” and that xenotransplantation is a potential solution to that quandary. “It can’t be understated the number of people waiting for a kidney on dialysis, which has a significant mortality rate,” he says. According to the advocacy group Donate Life America, more than 100,000 people in the U.S. alone are waiting for a donated organ, and 85 percent of them need a kidney.
Other experts believe the momentum for xenotransplantation is building, particularly given the recent successes. “I think there is a strong likelihood this will go mainstream,” says Brendan Parent, director of transplant ethics and policy at NYU Langone Health, a New York City-based hospital system. Like the UAB team, surgeons at NYU Langone have had success coaxing modified pig kidneys to work in deceased humans.
“There is a genuinely good chance that within a generation, (xenotransplantation) might become very common in reasonably wealthy countries,” says Michael Reiss, professor of science education at University College in London. In addition to his academic position, Reiss sits on the Nuffield Council on Bioethics, a nonprofit that is one of Britain’s most prominent watchdogs regarding medical and scientific issues. Reiss is also an Anglican priest and has studied xenotransplantation from both a scientific and religious point of view.
Moreover, genetic modifications could one day lead to organs being specifically optimized for their recipients. That could ensure issues like donor rejection and the calculated risk of artificially suppressing recipient immune systems become concerns of the past.
Major bioethical, religious concerns
Despite the promise of xenotransplantation, numerous bioethical issues swirl around the procedure. They could be magnified if xenotransplantation evolves from one-off experiments to a routine medical procedure.
One of the biggest is the millennia-long prohibitions Islam and Judaism have had regarding the consumption of pork. Will followers of these religions assume such rules extend to those taboo materials being inserted into a human body?
“Initially, one’s instinctual reaction is that, oh, crumbs! – how are Jews and Muslims going to react to that?” Reiss says. But in a world where science and secularism are accepted on an everyday basis, he notes it is not a significant issue. Reiss points out that valves from pig hearts have been used in human patients for decades without any issues. He adds that both Islam and Judaism waive religious dietary restrictions if a human life is at risk.
“While nobody's saying an individual patient is to be forced to have these, the very high proportion of people who identify as Jews or Muslims when given this option are content with it,” he says.
Concurring with Reiss is Michael Gusamano, professor of health policy at Lehigh University and director of its Center for Ethics. He is currently performing research on the ethics of xenotransplantation for the National Institutes of Health.
“Leaders from all major religions have commented on this and have indicated that this is not inconsistent with religious doctrine,” Gusamano says in written remarks to Leaps.org. “Having said that, it is plausible to believe that some people will assume that this is inconsistent with the teaching of their religion and may object to…receiving a xenotransplant as part of routine medical care.”
A history of clashes
Despite those assurances, science has long clashed with theology. Although Galileo proved the planets revolved around the sun, the Catholic Church found him guilty of heresy and rewarded his discovery with house arrest for the last decade of his life. A revolt occurred in mid-19th century India after native-born soldiers believed the ammunition supplied by their British occupiers had been lubricated with pork and beef tallow. Given they had to use their mouths to tear open ammunition pouches, this violated both the tenets of Islam and Hinduism. And one of the conspiracy theories hatched as a result of COVID-19 was that the vaccines developed to fight the disease were the “mark of the beast” – a sign of impending Armageddon under evangelical Christian theology.
The German xenotransplant research team has encountered such potential concerns when the procedure is regarded through a religious lens. “The pastors in our research suspected that many recipients might feel disgust and revulsion,” they write. “Even beyond these special religious reservations, cultural scripts about pigs as inferior living beings are also generally widespread and effective in the western world, so that here too possible disgust reactions cannot be ruled out.”
The German researchers add that “Jewish and Muslim hospital pastoral workers believe possible considerable problems in this respect, which must be dealt with psychosocially, religiously, and pastorally prior to a possible transplantation in order to strengthen the acceptance of the received organ by the patients and their relatives.”
Parent, the director at NYU Langone, shares a concern that xenotransplantation could move “too fast,” although much of his worry is focused on zoonotic disease transmission – pig viruses jumping into humans as a result of such procedures.
Another ethical issue
Moreover, the way pigs and other animals are raised for transplants could pose future ethical dilemmas.
Reiss notes that pigs raised for medical procedures have to be grown and kept in what are known as a designated pathogen-free facility, or DPF. Such facilities are kept painstakingly antiseptic so as to minimize the risk of zoonotic transmissions. But given pigs are fond of outdoor activities such as wallowing in mud and sleeping on hay, they lead “stunningly boring lives” that they probably do not enjoy, Reiss observes.
Ethical concerns with using pigs may push transplantation medicine into its next logical phase: Growing functional organs for transplant in a laboratory setting.
“There’s no doubt that these research pigs have gotten much better veterinary care, et cetera, (compared to farmed pigs). But it’s not a great life,” Reiss says. “And although it hasn’t so far dominated the discussion, I think as the years go by, rather as we’ve seen with the use of apes and now monkeys in medical research, more and more theologians will get uncomfortable about us just assuming we can do this with…pigs.”
The German research team raises the same concerns, but has taken a fairly sanguine view on the topic. “The impairments of the species-typical behavior will certainly provoke criticism and perhaps also public protest. But the number of animals affected is very small in relation to slaughter cattle,” the German researchers note. “Moreover, the conditions there and also in several animal experiments are far worse.”
Observers say that may push transplantation medicine into its next logical phase: Growing functional organs for transplant in a laboratory setting. Anderson, the UAB transplant surgeon, believes such an accomplishment remains decades away.
But other experts believe there is a moral imperative that xenotransplantation remain a temporary solution. “I think we have a duty to go in that direction,” Parent says. “We have to go that way, with the xenotransplantation process (as) a steppingstone and research path that will be useful for bioengineered organs.”
