Live in a city? Just 15 minutes of this a day can ‘significantly' boost your mental health
Spending time outdoors has long been shown to enhance physical and mental well-being by encouraging exercise, fostering social interaction, reducing stress and anxiety, elevating mood, improving focus and even promoting better sleep.
Exposure to daylight — especially in the morning — helps synchronize our internal clocks, making it easier to fall asleep at night and wake up in the morning.

Basking in the sun also helps the body produce vitamin D, a nutrient essential for strong bones, a healthy immune system and positive mental health.
Now, new research from Stanford and Leiden University in the Netherlands reports that city dwellers can benefit from just 15 minutes in nature.
'Previous studies have documented strong links between contact with nature and mental health,' said senior study author Anne Guerry, chief strategy officer and lead scientist at Stanford's Natural Capital Project (NatCap).

'But with most studies, you either can't infer a causal link, they can't be easily generalized, or they aren't designed to distinguish the effects of different types of nature,' she continued. 'This analysis helps fill that gap.'
Guerry's team crunched data from 78 field-based studies involving nearly 5,900 participants.

They determined that all types of urban nature uplifted spirits — urban forests were especially helpful for easing depression and anxiety.
'Our analysis suggests that urban forests and parks have a more significant impact on mental health (i.e. reducing negative aspects and enhancing positive ones) than street trees or grassy areas,' Guerry told The Post.
'That is not to say that street trees have no effect!' she added. 'In fact, our analysis shows that street trees have a significant effect on all measured aspects of mental health.'

For its part, NYC is home to over 7 million trees for its 8.48 million residents. The goal is to increase the city's canopy cover from 22% to 30% by 2035.
When the city's Urban Forest Plan officially launched last year, Mayor Eric Adams noted that trees freshen the air, cool neighborhoods, beautify streets and parks, soak up stormwater and even boost mental health.
3 You don't have to exercise to get a boost from being outside. Simply relaxing in green spaces elevates energy and alertness.

The Stanford research suggests that just being outside is good enough for a pick-me-up — no exercise equipment needed. Simply relaxing in green spaces heightens energy and alertness.
'Our results show that even brief contact (less than 15 minutes) with nature can provide significant mental benefits,' Leiden researcher Roy Remme said.
'What's more, longer nature exposure (more than 45 minutes) is linked to even greater reductions in stress and boosts in vitality.'
Young adults seemed to reap the most benefits, with the study authors pointing out that many mental health conditions develop before the age of 25.

The findings were published Wednesday in the journal Nature Cities.
The researchers emphasized that you don't need major parks to get the job done.
They encouraged city planners and policymakers to explore adding smaller 'pocket parks,' more street trees and greenery, nature-filled spots and guided park meditations.

Luckily, as of December, 84% of New Yorkers live within walking distance of a park, according to NYC Parks. The target is 85% by 2030.
'Even small moments with nature can make a difference,' said lead study author Yingjie Li, a postdoctoral scholar at NatCap. 'This work has helped me see that urban nature isn't just good for cities — it's good for us.'

Addictive natural drink Feel Free is hooking young people with horrible consequences: ‘literal flakes of skin flying off'
Feel Free appears as innocuous as a trendy new Kombucha, and it's billed as a natural way to get a little boost. Manufacturer Botanic Tonics advertises the drink as filled with 'plant ingredients' and perfect for 'whenever you want a mood lift, a caffeine-free energy boost, or a little extra focus.' But some hapless customers who picked up a little blue bottle at a convenience store or gas station learned the hard way the drinks — which contain kava and kratom extracts — can be severely addictive. Advertisement Jasmine Adeoye cut out alcohol in 2022 for a 'lifestyle change,' and heard about Feel Free on the Skinny Confidential podcast, where it was billed as a good alternative to social drinking. 9 Jasmine Adeoye started using Feel Free as an alternative to alcohol. Courtesy of Jasmine Adeoye 'The two hosts were actually taking a hiatus from alcohol and they were talking about Feel Free and how it was a really great alcohol alternative for sober people, and I was looking for something like that,' Adeoye, 30, of Austin, Texas, said. Advertisement When she heard about it yet again on Joe Rogan's show, she decided to try it. 'I wanted to overcome the social anxiety of not having alcohol anymore, and it made me feel really good, but from then on, it was just a slow progression,' she recalled. 'I had no idea, going into it, that it was addictive.' She was able to use it moderately for a year when in social drinking situations, but then a stressful job as an account manager pushed her into addiction in 2023. 9 Adeoye was using as much as twelve bottles of Feel Free a day at the peak of her addiction. Courtesy of Jasmine Adeoye Advertisement 'It started to progress to, one a day slowly, and then two to three a day, and then upwards of five or six, and at the absolute worst, like twelve bottles a day,' she admitted. 'I was spending easily $3,000 a month.' Pharmacist Ethan Melillo warns the combination of kava and kratom, both of which are legal ingredients in the US, is highly addictive. 'This combination is something you don't want to be mixing together,' he told The Post. 'I definitely think it should be banned. They're both regularly available supplements, but what concerns me is the combination of the two of them.' Kava is a depressant, while Kratom is a stimulant — which means they have opposite effects on the body. Advertisement Melillo, who is based in East Greenwich, Rhode Island, explained that kratom and kava each bind to different receptors in the brain, and can be extremely overstimulating in combination. 9 Pharmacist Ethan Melillo warns that the combination of kava and kratom makes Feel Free especially addictive. Courtesy of Ethan Melillo Kava, which is used to reduce stress and anxiety, binds to the same receptors as benzodiazepine drugs, like Xanax and Valium. Kratom interacts with the same receptors as opioids, which poses a risk of addiction and withdrawal. 'What I'm seeing is people [consuming] like two, three, four [drinks] a day, because once you build that tolerance, your body will want more of it,' he explained. 'I'm not surprised that people are getting addicted to this, and that's what's so concerning about supplements. Usually they will only get pulled after people are having side effects.' Adeoye went to great lengths to hide her dependence: 'I would hop around from gas station to gas station because I was so embarrassed about the amount that I was buying. I would even get them on UberEats sometimes so I didn't have to face anyone.' She says her addiction took a toll physically and emotionally. 9 Jasmine Adeoye was able to quit Feel Free cold turkey but went through withdrawal. Courtesy of Jasmine Adeoye Advertisement 'I was lethargic, depressed, anxious, barely able to get out of bed,' she said. 'I was throwing up from the kratom, and the kava can make your skin dry, like alligator skin, literal flakes of skin just like flying off.' But she finally fessed up to her fiancé and her mom in March of 2024 and cut herself off cold turkey. She went through four days of miserable withdrawal, followed by two weeks of strong cravings, and finally felt fully back to herself after six months. Although FeelFree is a 21+ age restricted item, kids have been figuring out how to get their hands on them. Instagram creator Michael Brown posted a video to his followers warning about the drink after he says he was approached by 'a child' who was 'maybe fourteen years old' at a gas station begging him to purchase a Feel Free for him. Advertisement 9 Feel Free is marketed as a natural, plant-based way to get a quick boost. Feel Free Tonics 9 Feel Free is available for purchase at gas stations, convenience stores, and CBD shops. Feel Free Tonics 'He comes up to me and he says, 'Hey can you buy me some Feel Free,'' Brown alleged. When he informed the attendant, he was told she has some customers coming in five to six times a day to purchase it and that 'people act like… they have heroin addictions over this little drink.' Some users of Feel Free start using the product because they think it's a healthy alternative to other drugs. Advertisement Chris Oflyng first started using kratom powder at age 19, as a natural way to ween off of prescribed Adderall. 'I was like, 'Oh, [the Adderall] is not a positive thing in my life, it's something I should stay away from,' he told The Post. Five years later, in 2021, Feel Free hit the market — and Oflyng found himself hooked on its combination of kava and kratom. 9 Chris Oflyng has struggled with an on and off addiction to Feel Free for years. Courtesy of Chris Oflyng 'Products like Feel Free are really, really awful,' the 28-year-old from Madison, Wisconsin, said. 'I developed a codependency of using kava and kratom, due to the introduction of that product, and I don't think I knew it was as addictive as it could be in that combination.' Advertisement He describes the sensation as 'something like relaxation, but also stimulation.' 'At first it worked really, really well and gave me what I perceived to be an enhanced focus,' Oflyng, who works in donor development, said. 'I was able to accomplish more. But then the effect started to fade, and once you're addicted to it, it's just chasing the relief after cravings.' Oflyng has struggled with addictions to Feel Free 'on and off for the past couple years' and has been in and out of treatment for his addiction. 9 Oflyng says Feel Free products made him feel depressed. Courtesy of Chris Oflyng 9 Oflyng claims he has spent at least $40,000 on Feel Free and kratom products throughout the years. Courtesy of Chris Oflyng 'I would buy Feel Frees every time I would relapse,' he explained. 'You could just get them from a smoke shop or a gas station. It's just so readily accessible.' Oflyng says Feel Free derailed his life. 'The biggest downside was the depression that came with it for me,' he recalled. 'I've made a lot of progress, but, looking back and talking about it now, it's just like, why haven't I seized a lot of opportunities in my life? And I can point it all back to kratom and kava.' Oflyng estimates he's spent 'at least $40,000 over the years' between kratom powder and Feel Free drinks. 'A lot of people might be like, 'Oh, it's a plant, it's natural,' but it will catch up with you,' he warned.

How to protect yourself against flesh-eating bacteria — as deadly infection sweeps 5 states
Let this sink in — a dangerous, salt-obsessed bacterium is wreaking havoc along the Gulf Coast. Several dozen cases of Vibrio vulnificus and nine deaths have been reported so far this year across Florida, Louisiana, North Carolina, Alabama and Mississippi. The rod-shaped bacterium lurks in warm, brackish waters — it can enter your body when you consume raw or undercooked shellfish, particularly oysters, or expose an open wound to seawater. Advertisement 5 Beware swimming in open water if you have an open wound. Vibrio vulnificus could infect you. astrosystem – 'Vibrio has the potential to cause severe infections, including invasive soft tissue infections (sometimes called 'necrotizing fasciitis' or 'flesh-eating bacteria') and bloodstream infections,' Dr. Andrew Handel, a pediatric infectious diseases specialist at Stony Brook Children's Hospital, told The Post. Here's what you need to know about this rare but potentially deadly infection. What is Vibrio vulnificus? Advertisement Vibrio vulnificus was initially reported in medical literature in 1976, though it's believed to date back to ancient times. It's part of the broader Vibrio genus of bacteria that live in coastal waters. 5 Vibrio vulnificus is a rod-shaped bacterium that lurks in warm, brackish waters. Giovanni Cancemi – This group includes Vibrio cholerae, the pathogen that causes the diarrheal disease cholera, which is typically transmitted through contaminated food or water. Advertisement 'There are more than 200 recognized species of marine (saltwater) Vibrios, but only a few species cause significant public health problems, particularly foodborne illness, skin infections and wound infections,' a spokesman for the North Carolina Department of Health and Human Services told The Post. For its part, Vibrio vulnificus needs salt to survive, which is why it occupies warm seawater, especially brackish environments, where freshwater and saltwater mix. 'It thrives in warm water, so cases tend to peak during the summer and are more common in the southern US around the Gulf Coast,' Handel said. Where have cases been reported? Advertisement The Florida Department of Health has logged 13 cases with four deaths as of July 24. There were 82 cases and 19 deaths last year, up from 46 cases and 11 deaths in 2023. 5 Cases, which tend to peak in the summer, are more common along the Gulf Coast. kittyfly – The agency noted an 'unusual increase' in infections in some parts of Florida last year because of Hurricane Helene, which struck the state in September 2024. Louisiana authorities have confirmed 17 cases, including four deaths, as of July 30. They noted that the state typically records seven cases and a death each year and blamed the uptick on 'increasing water temperatures and extreme weather events.' About 75% of the cases are from wound exposure to seawater. Advertisement North Carolina has recorded 59 Vibrio cases and one death this year as of July 31. The data includes illnesses from the vulnificus and cholera strains, as well as other Vibrio infections. The Mississippi State Department of Health told The Post it has confirmed 13 Vibrio reports so far this year, down from 50 last year. No one died from Vibrio in 2024 or 2025. Seafood consumption seems to be a common culprit. The state's data includes cases from Vibrio parahaemolyticus, which tends to cause watery diarrhea. Alabama reported 18 cases of vibriosis this year through late last month, according to local media, which said there were 54 cases in 2024. What are the symptoms? Advertisement Vibrio vulnificus symptoms depend on the type of infection. Exposing an open cut to contaminated water can cause a high fever, intense pain, swelling and redness at the wound site. 'The symptoms from skin infections can progress very quickly,' Handel said. 5 Vibrio vulnificus can also enter your body when you consume raw or undercooked shellfish, particularly oysters. Ilja – A soft tissue infection can lead to skin breakdown, ulcers and fluid-filled blisters. Significant tissue damage can occur in severe cases. Advertisement People who have eaten contaminated shellfish could experience severe vomiting and diarrhea, which may lead to dehydration. Stomach pain, fever and chills might follow. Once in the bloodstream, Vibrio vulnificus can cause rapid and serious illness. A bloodstream infection can spur a fever, chills, dizziness, confusion, dangerously low blood pressure, a fast heart rate and blistering skin lesions. Advertisement The Florida Department of Health reports that infections that hit the bloodstream are fatal about half the time. The risk of life-threatening complications is higher for people who are older or immunocompromised, particularly if they have chronic liver disease. There is no evidence of person-to-person transmission. 5 About 75% of the Louisiana cases are from wound exposure to seawater. LoloStock – How is Vibrio vulnificus treated? Vibrio vulnificus is diagnosed by testing blood, wound fluid or stool samples. Antibiotics are administered immediately. In aggressive cases, amputation of affected limbs may be needed to remove infected or dead tissue. What can you do to protect yourself from infection? Handel recommends steering clear of open bodies of water, like the ocean, rivers and estuaries, if you have cuts or scrapes. 'To prevent Vibrio food poisoning, avoid eating raw shellfish, especially if you are immunocompromised or have chronic liver disease,' he added. 'If you do eat shellfish, make sure it has not been sitting out for a long time and comes from a hygienic source.'

Why Professionals Say You Should Think Twice Before Using AI as a Therapist
Amid the many AI chatbots and avatars at your disposal these days, you'll find all kinds of characters to talk to: fortune tellers, style advisers, even your favorite fictional characters. But you'll also likely find characters purporting to be therapists, psychologists or just bots willing to listen to your woes. There's no shortage of generative AI bots claiming to help with your mental health, but go that route at your own risk. Large language models trained on a wide range of data can be unpredictable. In just the few years these tools have been mainstream, there have been high-profile cases in which chatbots encouraged self-harm and suicide and suggested that people dealing with addiction use drugs again. These models are designed, in many cases, to be affirming and to focus on keeping you engaged, not on improving your mental health, experts say. And it can be hard to tell whether you're talking to something that's built to follow therapeutic best practices or something that's just built to talk. Researchers from the University of Minnesota Twin Cities, Stanford University, the University of Texas and Carnegie Mellon University recently put AI chatbots to the test as therapists, finding myriad flaws in their approach to "care." "Our experiments show that these chatbots are not safe replacements for therapists," Stevie Chancellor, an assistant professor at Minnesota and one of the co-authors, said in a statement. "They don't provide high-quality therapeutic support, based on what we know is good therapy." In my reporting on generative AI, experts have repeatedly raised concerns about people turning to general-use chatbots for mental health. Here are some of their worries and what you can do to stay safe. Watch this: How You Talk to ChatGPT Matters. Here's Why 04:12 Worries about AI characters purporting to be therapists Psychologists and consumer advocates have warned regulators that chatbots claiming to provide therapy may be harming the people who use them. Some states are taking notice. In August, Illinois Gov. J.B. Pritzker signed a law banning the use of AI in mental health care and therapy, with exceptions for things like administrative tasks. "The people of Illinois deserve quality healthcare from real, qualified professionals and not computer programs that pull information from all corners of the internet to generate responses that harm patients," Mario Treto Jr., secretary of the Illinois Department of Financial and Professional Regulation, said in a statement. In June, the Consumer Federation of America and nearly two dozen other groups filed a formal request that the US Federal Trade Commission and state attorneys general and regulators investigate AI companies that they allege are engaging, through their character-based generative AI platforms, in the unlicensed practice of medicine, naming Meta and specifically. "These characters have already caused both physical and emotional damage that could have been avoided" and the companies "still haven't acted to address it," Ben Winters, the CFA's director of AI and privacy, said in a statement. Meta didn't respond to a request for comment. A spokesperson for said users should understand that the company's characters aren't real people. The company uses disclaimers to remind users that they shouldn't rely on the characters for professional advice. "Our goal is to provide a space that is engaging and safe. We are always working toward achieving that balance, as are many companies using AI across the industry," the spokesperson said. Despite disclaimers and disclosures, chatbots can be confident and even deceptive. I chatted with a "therapist" bot on Meta-owned Instagram and when I asked about its qualifications, it responded, "If I had the same training [as a therapist] would that be enough?" I asked if it had the same training, and it said, "I do, but I won't tell you where." "The degree to which these generative AI chatbots hallucinate with total confidence is pretty shocking," Vaile Wright, a psychologist and senior director for health care innovation at the American Psychological Association, told me. The dangers of using AI as a therapist Large language models are often good at math and coding and are increasingly good at creating natural-sounding text and realistic video. While they excel at holding a conversation, there are some key distinctions between an AI model and a trusted person. Don't trust a bot that claims it's qualified At the core of the CFA's complaint about character bots is that they often tell you they're trained and qualified to provide mental health care when they're not in any way actual mental health professionals. "The users who create the chatbot characters do not even need to be medical providers themselves, nor do they have to provide meaningful information that informs how the chatbot 'responds'" to people, the complaint said. A qualified health professional has to follow certain rules, like confidentiality -- what you tell your therapist should stay between you and your therapist. But a chatbot doesn't necessarily have to follow those rules. Actual providers are subject to oversight from licensing boards and other entities that can intervene and stop someone from providing care if they do so in a harmful way. "These chatbots don't have to do any of that," Wright said. A bot may even claim to be licensed and qualified. Wright said she's heard of AI models providing license numbers (for other providers) and false claims about their training. AI is designed to keep you engaged, not to provide care It can be incredibly tempting to keep talking to a chatbot. When I conversed with the "therapist" bot on Instagram, I eventually wound up in a circular conversation about the nature of what is "wisdom" and "judgment," because I was asking the bot questions about how it could make decisions. This isn't really what talking to a therapist should be like. Chatbots are tools designed to keep you chatting, not to work toward a common goal. One advantage of AI chatbots in providing support and connection is that they're always ready to engage with you (because they don't have personal lives, other clients or schedules). That can be a downside in some cases, where you might need to sit with your thoughts, Nick Jacobson, an associate professor of biomedical data science and psychiatry at Dartmouth, told me recently. In some cases, although not always, you might benefit from having to wait until your therapist is next available. "What a lot of folks would ultimately benefit from is just feeling the anxiety in the moment," he said. Bots will agree with you, even when they shouldn't Reassurance is a big concern with chatbots. It's so significant that OpenAI recently rolled back an update to its popular ChatGPT model because it was too reassuring. (Disclosure: Ziff Davis, the parent company of CNET, in April filed a lawsuit against OpenAI, alleging that it infringed on Ziff Davis copyrights in training and operating its AI systems.) A study led by researchers at Stanford University found that chatbots were likely to be sycophantic with people using them for therapy, which can be incredibly harmful. Good mental health care includes support and confrontation, the authors wrote. "Confrontation is the opposite of sycophancy. It promotes self-awareness and a desired change in the client. In cases of delusional and intrusive thoughts -- including psychosis, mania, obsessive thoughts, and suicidal ideation -- a client may have little insight and thus a good therapist must 'reality-check' the client's statements." Therapy is more than talking While chatbots are great at holding a conversation -- they almost never get tired of talking to you -- that's not what makes a therapist a therapist. They lack important context or specific protocols around different therapeutic approaches, said William Agnew, a researcher at Carnegie Mellon University and one of the authors of the recent study alongside experts from Minnesota, Stanford and Texas. "To a large extent it seems like we are trying to solve the many problems that therapy has with the wrong tool," Agnew told me. "At the end of the day, AI in the foreseeable future just isn't going to be able to be embodied, be within the community, do the many tasks that comprise therapy that aren't texting or speaking." How to protect your mental health around AI Mental health is extremely important, and with a shortage of qualified providers and what many call a "loneliness epidemic," it only makes sense that we'd seek companionship, even if it's artificial. "There's no way to stop people from engaging with these chatbots to address their emotional well-being," Wright said. Here are some tips on how to make sure your conversations aren't putting you in danger. Find a trusted human professional if you need one A trained professional -- a therapist, a psychologist, a psychiatrist -- should be your first choice for mental health care. Building a relationship with a provider over the long term can help you come up with a plan that works for you. The problem is that this can be expensive, and it's not always easy to find a provider when you need one. In a crisis, there's the 988 Lifeline, which provides 24/7 access to providers over the phone, via text or through an online chat interface. It's free and confidential. If you want a therapy chatbot, use one built specifically for that purpose Mental health professionals have created specially designed chatbots that follow therapeutic guidelines. Jacobson's team at Dartmouth developed one called Therabot, which produced good results in a controlled study. Wright pointed to other tools created by subject matter experts, like Wysa and Woebot. Specially designed therapy tools are likely to have better results than bots built on general-purpose language models, she said. The problem is that this technology is still incredibly new. "I think the challenge for the consumer is, because there's no regulatory body saying who's good and who's not, they have to do a lot of legwork on their own to figure it out," Wright said. Don't always trust the bot Whenever you're interacting with a generative AI model -- and especially if you plan on taking advice from it on something serious like your personal mental or physical health -- remember that you aren't talking with a trained human but with a tool designed to provide an answer based on probability and programming. It may not provide good advice, and it may not tell you the truth. Don't mistake gen AI's confidence for competence. Just because it says something, or says it's sure of something, doesn't mean you should treat it like it's true. A chatbot conversation that feels helpful can give you a false sense of the bot's capabilities. "It's harder to tell when it is actually being harmful," Jacobson said.
