    How to Exercise to Improve Your Mood

    Physical activity can brighten your outlook and calm your nerves — if you do it strategically.We’ve all encountered that person who comes back from the gym or a run seemingly high on life. In fact, scientists say that even a single bout of exercise can alter your neurochemistry in ways that create feelings of hope, calm, connection and a generally better mood.But for others, a workout just leaves them feeling worn out.“It’s normal not to find exercise rewarding,” said Daniel Lieberman, an evolutionary biologist at Harvard University. “There’s nothing wrong with you.”While some people are simply more genetically or psychologically inclined to enjoy exercise, recent discoveries have helped experts understand why it can be such a high. And, they say, by making a few changes to your workout, you can train your body and mind to find exercise more pleasurable.It’s not just about endorphins.Scientists once thought the rush people felt from exercise came exclusively from endorphins, which act like natural opioids in the brain by relieving pain. But in recent decades, researchers have discovered a more complex cocktail of other key “feel-good” chemicals produced during movement.Each ingredient plays a distinct but complementary role, said Julia Basso, an assistant professor at Virginia Tech who runs a lab studying the effects of exercise on the brain. “These neurochemicals are really working in tandem,” she said.The most potent players appear to be endocannabinoids, which share similar molecular structure with THC, and bind to the same receptors in the brain — giving you that buzzy feeling that all is right in the world.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Moving In Childhood Contributes to Depression, Study Finds

    A study of more than a million Danes found that frequent moves in childhood had a bigger effect than poverty on adult mental health risk.In recent decades, mental health providers began screening for “adverse childhood experiences” — generally defined as abuse, neglect, violence, family dissolution and poverty — as risk factors for later disorders.But what if other things are just as damaging?Researchers who conducted a large study of adults in Denmark, published on Wednesday in the journal JAMA Psychiatry, found something they had not expected: Adults who moved frequently in childhood have significantly more risk of suffering from depression than their counterparts who stayed put in a community.In fact, the risk of moving frequently in childhood was significantly greater than the risk of living in a poor neighborhood, said Clive Sabel, a professor at the University of Plymouth and the paper’s lead author.“Even if you came from the most income-deprived communities, not moving — being a ‘stayer’ — was protective for your health,” said Dr. Sabel, a geographer who studies the effect of environment on disease.“I’ll flip it around by saying, even if you come from a rich neighborhood, but you moved more than once, that your chances of depression were higher than if you hadn’t moved and come from the poorest quantile neighborhoods,” he added.The study, a collaboration by Aarhus University, the University of Manchester and the University of Plymouth, included all Danes born between 1982 and 2003, more than a million people. Of those, 35,098, or around 2.3 percent, received diagnoses of depression from a psychiatric hospital.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    This Is Literally Your Brain on Drugs

    A small new study shows reactions in the brain in people who were given psilocybin in a controlled setting.If you had to come up with a groovy visualization of the human brain on psychedelic drugs, it might look something like this.Sara Moser/Washington University School of MedicineThe image, as it happens, comes from dozens of brain scans produced by researchers at Washington University School of Medicine in St. Louis who gave psilocybin, the compound in “magic mushrooms,” to participants in a study before sending them into a functional M.R.I. scanner.The kaleidoscopic whirl of colors they recorded is essentially a heat map of brain changes, with the red, orange and yellow hues reflecting a significant departure from normal activity patterns. The blues and greens reflect normal brain activity that occurs in the so-called functional networks, the neural communication pathways that connect different regions of the brain.The scans, published Wednesday in the journal Nature, offer a rare glimpse into the wild neural storm associated with mind-altering drugs. Researchers say they could provide a potential road map for understanding how psychedelic compounds like psilocybin, LSD and MDMA can lead to lasting relief from depression, anxiety and other mental health disorders.“Psilocybin, in contrast to any other drug we’ve tested, has this massive effect on the whole brain that was pretty unexpected,” said Dr. Nico Dosenbach, a professor of neurology at Washington University and a senior author of the study. “It was quite shocking when we saw the effect size.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    The Reason People Aren’t Telling Joe Biden the Truth

    They entered with courage and exited as cowards. In the past two weeks, several leaders have told me they arrived at meetings with President Biden planning to have serious discussions about whether he should withdraw from the 2024 election. They all chickened out.I don’t know whether Mr. Biden should drop out of the race. It’s impossible to predict the outcome with certainty. My concern is about the decision process. There’s a gap between what people say behind the president’s back and what they say to his face. Instead of dissent and debate, they’re falling victim to groupthink.According to the original theory, groupthink happens when people become so cohesive and close-knit that they put harmony above honesty. Extensive evidence has debunked that idea. The root causes of silence are not social solidarity but fear and futility. People bite their tongues when they doubt that it’s safe and worthwhile to speak up. Leaders who want to make informed decisions need to make it clear they value candid input.Mr. Biden has done the opposite, declaring first that only the Lord almighty could change his mind and then saying that he’ll drop out only if polls say there’s no way for him to win. That sends a strong message: If you’re not an immortal being or a time traveler from the future, it’s pointless to share any concerns about the viability of his candidacy.The president is in a tough spot. Even conceding privately that he might consider stepping aside could crush the confidence of his advisers and risk a leak to the press. But a little humility could go a long way: “I believe I’m the best qualified to govern, but I don’t know for sure. I think I can win, but I might be wrong.” Along with inviting dissent, these acts of receptiveness might make Mr. Biden more persuasive. People put more faith in a balanced argument and a leader who wants to learn.Showing openness can raise people’s confidence, but it’s not always enough to quell their fear. In our research, Constantinos Coutifaris and I found that it helps for leaders to criticize themselves out loud. That way, instead of just claiming that they want the truth, they can show that they can handle the truth. If he hasn’t already, Mr. Biden could do that by gathering his family and advisers to watch a video of the debate with him and then kicking off a candid discussion by talking about what he thought he did wrong. Reviewing the game tape together would demonstrate that he’s willing to take an honest look in the mirror.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Choosing to Forgive Can Be Terrifying — and Healing

    Choosing to forgive can be frightening, but it’s a powerful tool for repairing the harm done by violence, oppression and other traumas.This essay is part of a series called The Big Ideas, in which writers respond to a single question: What do we fear? You can read more by visiting The Big Ideas series page.In the years I served on South Africa’s Truth and Reconciliation Commission, I came to a surprising conclusion. It crystallized when I invited the daughter of an anti-apartheid activist to the University of the Free State in Bloemfontein, where I held an endowed chair position, to speak about her encounter with the man who killed her mother. Marcia Khoza was 5 years old when her mother was murdered in a raid led by Eugene de Kock, the former head of the apartheid government’s covert hit squad operations. On the 23rd anniversary of her mother’s death, Khoza went to see de Kock in prison, carrying a book on forgiveness that she bought for him. Inside the book she wrote: “Let the power of peace and forgiveness guide you.”At the University of the Free State event, Khoza described growing up with a deepening void of emptiness. “I carried so much anger,” she said, and she let the anger intensify to protect herself “from falling into the abyss.” She wanted to meet de Kock to fill the gaps of unanswered questions about her mother’s killing, and as part of her search for inner peace, she was ready to forgive him.When I joined the commission, it seemed counterintuitive that meeting someone who has murdered a loved one could be restorative for either person. But forgiveness, I came to realize, is perhaps the most powerful means of restoring a sense of coherence and continuity in the lives of survivors of historical wrongs. It can also be an incredibly frightening concept to embrace.Noma Dumezweni, left, and Matthew Marsh perform in “A Human Being Died That Night” at the Brooklyn Academy of Music in New York. The play is based on the book of the same name, written by Pumla Gobodo-Madikizela, that examines atrocities committed by the South African police forces during apartheid.Michelle V. Agins/The New York TimesForgiveness emerges from both within and outside the place of hurt, and it requires a degree of intentional openness, of reaching out beyond oneself toward the other. Therein lies both its transformative potential and its moral ambiguity — and this is what is most frightening about forgiveness. The inward psychological journey necessary before we can forgive enables us to see the humanity of those responsible for our wounding, and, having forgiven them, admit them into our world of common humanity.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Why Adult ADHD Is Hard to Diagnose

    It’s one of the most common psychiatric disorders in adults. Yet there are no U.S. guidelines for diagnosing and treating patients beyond childhood.Just before Katie Marsh dropped out of college, she began to worry that she might have attention deficit hyperactivity disorder.“Boredom was like a burning sensation inside of me,” said Ms. Marsh, who is now 30 and lives in Portland, Ore. “I barely went to class. And when I did, I felt like I had a lot of pent-up energy. Like I had to just move around all the time.”So she asked for an A.D.H.D. evaluation — but the results, she was surprised to learn, were inconclusive. She never did return to school. And only after seeking help again four years later was she diagnosed by an A.D.H.D. specialist.“It was pretty frustrating,” she said.A.D.H.D. is one of the most common psychiatric disorders in adults. Yet many health care providers have uneven training on how to evaluate it, and there are no U.S. clinical practice guidelines for diagnosing and treating patients beyond childhood.Without clear rules, some providers, while well-intentioned, are just “making it up as they go along,” said Dr. David W. Goodman, an assistant professor of psychiatry and behavioral sciences at the Johns Hopkins University School of Medicine.This lack of clarity leaves providers and adult patients in a bind.“We desperately need something to help guide the field,” said Dr. Wendi Waits, a psychiatrist with Talkiatry, an online mental health company. “When everyone’s practicing somewhat differently, it makes it hard to know how best to approach it.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    The Psychedelic Evangelist

    Before he died last year, Roland Griffiths was arguably the world’s most famous psychedelics researcher. Since 2006, his work has suggested that psilocybin, found in magic mushrooms, can induce mystical experiences, and that those experiences, in turn, can help treat anxiety, depression, addiction and the terror of death.Dr. Griffiths and his colleagues at Johns Hopkins University received widespread recognition among scientists and the popular press, helping to pull the psychedelic field from the deep backwater of the 1960s hippie movement. This second wave of research on the hallucinogenic compounds bolstered political campaigns to decriminalize them and spurred biotech investment.Dr. Griffiths was known to friends and colleagues as an analytical thinker and a religious agnostic, and he warned fellow researchers against hype. But he also saw psychedelics as more than mere medicines: Understanding them could be “critical to the survival of the human species,” he said in one talk. Late in life, he admitted to taking psychedelics himself, and said he wanted science to help unlock their transformative power for humanity.Perhaps unsurprisingly, he held a vaunted, even prophetic role among psychonauts, the growing community of psychedelic believers who want to bring the drugs into mainstream society. For years, critics have denounced the outsize financial and philosophical influence of these advocates on the insular research field. And some researchers have quietly questioned whether Dr. Griffiths, in his focus on the mystical realm, made some of the same mistakes that doomed the previous era of psychedelic science.Now, one of his longtime collaborators is airing a more forceful critique. “Dr. Griffiths has run his psychedelic studies more like a ‘new-age’ retreat center, for lack of a better term, than a clinical research laboratory,” reads an ethics complaint filed to Johns Hopkins last fall by Matthew Johnson, who worked with Dr. Griffiths for nearly 20 years but resigned after a charged dispute with colleagues.Roland Griffiths, director of the Center for Psychedelic and Consciousness Research at Johns Hopkins, in 2021.Matt Roth for The New York TimesWe are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    ‘Space: The Longest Goodbye’ Review

    This documentary by Ido Mizrahy examines the psychological challenges of space exploration for astronauts and their loved ones as scientists consider whether humans could reach Mars.In “Space: The Longest Goodbye,” scientists researching the problems of long-term space exploration go where movies have gone before. Sending astronauts into hibernation to conserve scarce resources? Pairing them with an artificially intelligent entity that can act as a pal and sounding board? Screenwriters have tried these things already, with results probably best kept in fiction.But such gambits may offer real solutions for getting humans to Mars. And they are gambits that this fitfully intriguing, sometimes wide-eyed documentary, directed by Ido Mizrahy, takes seriously.“Soft, squishy humans are completely unfathomable to engineers,” says Jack Stuster, an anthropologist who asked residents of the International Space Station to keep journals. One of the principal interviewees is Al Holland, a psychologist who assembled a unit at the National Aeronautics and Space Administration to provide support for astronauts. He discusses his experience in 2010 consulting on the Chilean mine disaster, which had striking parallels with the isolation of space life.We also hear from Kayla Barron, a submarine warfare officer who decided to go to space, and her husband, who stayed behind; as a military couple, they were used to living separately, but this posed a different challenge. And we see clips of personal video chats that the astronaut Cady Coleman held with her husband and son back on Earth, through a system that sometimes didn’t work. “It’s hard for me to really realize how hard it was for a little kid to just have to be so very patient,” she recalls in the documentary.On Mars missions, distance will make similar real-time communication impossible, which means that astronauts won’t even have that kind of intermittent contact. “Space: The Longest Goodbye” leaves open the question of whether anyone could get to the red planet with his or her sanity intact.Space: The Longest GoodbyeNot rated. Running time: 1 hour 27 minutes. In theaters and available to rent or buy on most major platforms. More
