Do exercise, nature and socializing make people happier? Research suggests we don't really know – CBC.ca

Hannah Ali feels happiest when she can take her dog, Ella, out for a walk and meet up with her friends. 

“Humans are social animals, so when you spend time with your friends, your family … I think that’s what makes you the most happy,” said Ali, a Toronto resident. 

As an immigrant to Canada, Ali says she knows a lot of people who also left family and friends behind in their home countries and she sees how losing those social connections impacts them. 

“They miss the social aspect of it,” she said. “I think that really affects their mood and their overall quality of life here.” 

But a recent review of research on the subject suggests that despite decades of scientific studies, experts still don’t know whether some of the most common happiness-boosting strategies — such as socializing — actually work. 

Happiness is a feeling that people can spend their whole lives chasing. Often, that pursuit involves doing certain activities, such as seeing friends or going outside for a walk. 

Researchers at the University of British Columbia (UBC) decided to look into whether there is robust evidence to support the effectiveness of these activities. They began by searching phrases such as “scientifically proven ways to be happier” on Google and looked at the activities recommended within the links in the first 10 pages of results. 

From there, they identified the following five most common ways people are advised to seek happiness: 

  • Socializing. 
  • Being in nature. 
  • Expressing gratitude.
  • Exercising.
  • Mindfulness/meditation. 

After reviewing dozens of studies that focused on these five strategies, they found there’s not a lot of rigorous research to prove they make us any happier.

The review’s senior author cautions that the results shouldn’t discourage those who enjoy the suggested activities.

“If you’re somebody who, for example, works out every day and really enjoys it — absolutely, you should stick with it, and if you find that it makes you happy, that’s fabulous,” said Elizabeth Dunn, a psychology professor at UBC. 

“All we’re saying is that there isn’t really strong evidence that, across the board for the typical person, that exercise … or that these other strategies reliably promote happiness.”  

The review’s lead author, Dunigan Folk, says that while people shouldn’t stop doing what makes them happy, the findings are important for those who sink time or money into trying to feel good. 

“It can be frustrating if you’re trying something that at least the consensus suggests is strongly scientifically backed and it doesn’t work for you, and that can lead to feelings of hopelessness,” said Folk, a PhD student in psychology at UBC.

‘The evidence isn’t there yet’

The study defined happiness as “subjective well-being,” which includes having more positive feelings than negative ones and feeling satisfied with life overall. 

The researchers scoured the literature to find randomized controlled trials that followed what they say are the most up-to-date, robust experimental standards. In particular, they wanted to ensure that the studies involved large numbers of participants and that the studies’ authors had predetermined how they were going to analyze the data, both of which make it more likely that the results could be replicated.

The authors looked at studies that, depending on their design, had a minimum of 45 participants or 86 if testing only one intervention.

They whittled down more than 11,000 studies to 57 that were peer-reviewed and met their criteria. Most of the articles were published after the year 2000. 

From these, they discovered that the five most reported on strategies have very little robust research that would suggest they reliably improve mood. 

“It’s not like there’s strong evidence that these things don’t work,” said Folk.

“It’s just the fact that these studies tended not to meet the standards for high-quality evidence, and so it’s hard to know exactly what the effects of these behaviours are on happiness.”

While strong evidence of their effectiveness is slim, gratitude and social interactions, such as talking to strangers and being more outgoing, had slightly more research to support their impact on happiness, according to the researchers. 

“The evidence isn’t necessarily there yet that these strategies are really broadly helpful in terms of promoting happiness at a population level,” Dunn said. 

But experts who use activities such as exercise and mindfulness in their work say that happiness can be a nuanced concept and that the researchers’ criteria is too limiting. 

Two experts who spoke with CBC took issue with three aspects of Dunn and Folk’s approach in particular:

1. They only included studies with patients who had a baseline level of happiness.

Dunn and Folk limited their search to studies that involved people who weren’t diagnosed with a mood disorder, such as anxiety or depression. 

Eli Puterman, Canada Research Chair in Physical Activity and Health at UBC, says that is “a major flaw,” because people who are trying to become happier often have more depressive symptoms, according to some research. 

“So, you’re excluding the people who would need these [activities] the most,” said Puterman, who is also an associate professor of kinesiology at UBC. 

“If you’re already happy, how do I make you happier? I can only move your happiness and your well-being if you have low well-being.” 

Eli Puterman, left, is an associate professor at the University of British Columbia’s School of Kinesiology and Bassam Khoury is an associate professor in educational and counselling psychology at McGill University. They are both critical of Dunn and Folks’ findings, though they agree the field could always use more robust evidence. (Jennifer La Grassa/CBC, Submitted by Bassam Khoury)

Puterman says the majority of randomized control trials on exercise focus on people who have a diagnosis or symptoms of a mental health disorder. 

Often, he says, these studies have findings related to mood, but those might be a secondary outcome and not the initial focus, so they would not have been captured in Dunn and Folk’s review. 

That research, says Puterman, has reliably shown that people who exercise experience improved mental health and well-being — whether they have mental health symptoms or not. 

Similarly, Bassam Khoury, an associate professor in educational and counselling psychology at McGill University in Montreal whose research focuses on mindfulness, says much of the most promising research on the effectiveness of mindfulness has been in people with a clinical diagnosis or symptoms of psychiatric disorders. 

2. They excluded smaller studies and those that didn’t commit to how data would be analyzed.

Khoury says that in setting a high threshold for the size of studies they were willing to include, Dunn and Folk didn’t give enough consideration to the fact that studies in the area of well-being research can have trouble retaining participants. 

Typically, researchers need to track mood for a few hours a week over a couple of months. Longer studies run the risk of people dropping out. And studies with large numbers of people that extend over long periods often cost more money to run. 

As a result, he says, mindfulness-based intervention studies can be more challenging than other types of social science experiments, for example, where researchers might need to only spend 15 to 20 minutes with each participant.

But just because a study is smaller doesn’t mean it should be disregarded, Khoury says. 

Meanwhile, Puterman says the refusal to include studies that didn’t pre-commit to their analysis was “flawed” because that approach only became standard in the last decade while much of the research in this field came out prior to that. 

As a result, he fears the researchers may have thrown out “some of the most important research in this field.”

Folk acknowledges that even if studies had a high number of participants and researchers predetermined how they’d analyze their findings, it doesn’t mean the research is flawless. But, he says, these are the best current standards to measure research against and ensure it’s of higher quality. 

3. Their definition of happiness was narrow.

The authors recognize that they used a very strict definition of happiness and didn’t really consider other feelings that could indirectly impact someone’s mood. 

Khoury says that approach means the review didn’t capture other beneficial effects of the five strategies that might have happiness as a byproduct.

In particular, he says, they didn’t look at studies that measure quality of life, which is often used in mindfulness research. 

Khoury points to a systematic review from 2020 that didn’t look specifically at happiness but found that mindfulness strategies can increase well-being and quality of life in people who don’t have mental health issues.

Researchers say their work is a call to action for the scientific community to do more robust studies that match contemporary research standards to provide more evidence that these sorts of happiness strategies work. (Jennifer La Grassa/CBC)

Khoury called Dunn and Folk’s conclusions “a bit premature and not nuanced” and said it’s precisely that nuance that makes study in this area so complex. 

“I should not only meditate because I want to be happier,” he said. “I should come to meditate [because I] want to be more aware, more present, more understanding and maybe a better person.”

More rigorous evidence needed

Both Khoury and Puterman agree that more robust trials are needed, but they disagree with how the review supports that aim. 

“We do need better trials, we do need better evidence … [but] I do not believe you throw out all previous evidence as a result of that,” said Puterman. 

He says he would have liked to see the researchers assess all of the available research and rate it for how good or bad it is and then separately evaluate the studies that met their high-quality criteria. 

Dunn and Folk say they hope their findings are a call to action for the research community. 

“One thing we’ve … discovered is that the public really cares about these approaches,” said Dunn. “There’s a lot of interest in them, and so I think we need to do the hard work to put them to [a] more rigorous test.”

Social interaction, especially talking to strangers and being outgoing, was one of the mood-boosting activities that researchers found had more robust evidence for increasing happiness than others. (Jennifer La Grassa/CBC)

As for Ali, while she’s surprised with the review’s findings, no amount of scientific research is likely to make her reconsider her choices about where she finds happiness. 

“It’s not going to change my mind, certainly,” she said. “I’ll keep doing things that make me happy.”

Health Canada approves updated Moderna COVID-19 vaccine

Published

 on

 

TORONTO – Health Canada has authorized Moderna’s updated COVID-19 vaccine that protects against currently circulating variants of the virus.

The mRNA vaccine, called Spikevax, has been reformulated to target the KP.2 subvariant of Omicron.

It will replace the previous version of the vaccine that was released a year ago, which targeted the XBB.1.5 subvariant of Omicron.

Health Canada recently asked provinces and territories to get rid of their older COVID-19 vaccines to ensure the most current vaccine will be used during this fall’s respiratory virus season.

Health Canada is also reviewing two other updated COVID-19 vaccines but has not yet authorized them.

They are Pfizer’s Comirnaty, which is also an mRNA vaccine, as well as Novavax’s protein-based vaccine.

These people say they got listeria after drinking recalled plant-based milks

Published

 on

 

TORONTO – Sanniah Jabeen holds a sonogram of the unborn baby she lost after contracting listeria last December. Beneath, it says “love at first sight.”

Jabeen says she believes she and her baby were poisoned by a listeria outbreak linked to some plant-based milks and wants answers. An investigation continues into the recall declared July 8 of several Silk and Great Value plant-based beverages.

“I don’t even have the words. I’m still processing that,” Jabeen says of her loss. She was 18 weeks pregnant when she went into preterm labour.

The first infection linked to the recall was traced back to August 2023. One year later on Aug. 12, 2024, the Public Health Agency of Canada said three people had died and 20 were infected.

The number of cases is likely much higher, says Lawrence Goodridge, Canada Research Chair in foodborne pathogen dynamics at the University of Guelph: “For every person known, generally speaking, there’s typically 20 to 25 or maybe 30 people that are unknown.”

The case count has remained unchanged over the last month, but the Public Health Agency of Canada says it won’t declare the outbreak over until early October because of listeria’s 70-day incubation period and the reporting delays that accompany it.

Danone Canada’s head of communications said in an email Wednesday that the company is still investigating the “root cause” of the outbreak, which has been linked to a production line at a Pickering, Ont., packaging facility.

Pregnant people, adults over 60, and those with weakened immune systems are most at risk of becoming sick with severe listeriosis. If the infection spreads to an unborn baby, Health Canada says it can cause miscarriage, stillbirth, premature birth or life-threatening illness in a newborn.

The Canadian Press spoke to 10 people, from the parents of a toddler to an 89-year-old senior, who say they became sick with listeria after drinking from cartons of plant-based milk stamped with the recalled product code. Here’s a look at some of their experiences.

Sanniah Jabeen, 32, Toronto

Jabeen says she regularly drank Silk oat and almond milk in smoothies while pregnant, and began vomiting seven times a day and shivering at night in December 2023. She had “the worst headache of (her) life” when she went to the emergency room on Dec. 15.

“I just wasn’t functioning like a normal human being,” Jabeen says.

Told she was dehydrated, Jabeen was given fluids and a blood test and sent home. Four days later, she returned to hospital.

“They told me that since you’re 18 weeks, there’s nothing you can do to save your baby,” says Jabeen, who moved to Toronto from Pakistan five years ago.

Jabeen later learned she had listeriosis and an autopsy revealed her baby was infected, too.

“It broke my heart to read that report because I was just imagining my baby drinking poisoned amniotic fluid inside of me. The womb is a place where your baby is supposed to be the safest,” Jabeen said.

Jabeen’s case is likely not included in PHAC’s count. Jabeen says she was called by Health Canada and asked what dairy and fresh produce she ate – foods more commonly associated with listeria – but not asked about plant-based beverages.

She’s pregnant again, and is due in several months. At first, she was scared to eat, not knowing what caused the infection during her last pregnancy.

“Ever since I learned about the almond, oat milk situation, I’ve been feeling a bit better knowing that it wasn’t something that I did. It was something else that caused it. It wasn’t my fault,” Jabeen said.

She’s since joined a proposed class action lawsuit launched by LPC Avocates against the manufacturers and sellers of Silk and Great Value plant-based beverages. The lawsuit has not yet been certified by a judge.

Natalie Grant and her seven year-old daughter, Bowmanville, Ont.

Natalie Grant says she was in a hospital waiting room when she saw a television news report about the recall. She wondered if the dark chocolate almond milk her daughter drank daily was contaminated.

She had brought the girl to hospital because she was vomiting every half hour, constantly on the toilet with diarrhea, and had severe pain in her abdomen.

“I’m definitely thinking that this is a pretty solid chance that she’s got listeria at this point because I knew she had all the symptoms,” Grant says of seeing the news report.

Once her daughter could hold fluids, they went home and Grant cross-checked the recalled product code – 7825 – with the one on her carton. They matched.

“I called the emerg and I said I’m pretty confident she’s been exposed,” Grant said. She was told to return to the hospital if her daughter’s symptoms worsened. An hour and a half later, her fever spiked, the vomiting returned, her face flushed and her energy plummeted.

Grant says they were sent to a hospital in Ajax, Ont. and stayed two weeks while her daughter received antibiotics four times a day until she was discharged July 23.

“Knowing that my little one was just so affected and how it affected us as a family alone, there’s a bitterness left behind,” Grant said. She’s also joined the proposed class action.

Thelma Feldman, 89, Toronto

Thelma Feldman says she regularly taught yoga to friends in her condo building before getting sickened by listeria on July 2. Now, she has a walker and her body aches. She has headaches and digestive problems.

“I’m kind of depressed,” she says.

“It’s caused me a lot of physical and emotional pain.”

Much of the early days of her illness are a blur. She knows she boarded an ambulance with profuse diarrhea on July 2 and spent five days at North York General Hospital. Afterwards, she remembers Health Canada officials entering her apartment and removing Silk almond milk from her fridge, and volunteers from a community organization giving her sponge baths.

“At my age, 89, I’m not a kid anymore and healing takes longer,” Feldman says.

“I don’t even feel like being with people. I just sit at home.”

Jasmine Jiles and three-year-old Max, Kahnawake Mohawk Territory, Que.

Jasmine Jiles says her three-year-old son Max came down with flu-like symptoms and cradled his ears in what she interpreted as a sign of pain, like the one pounding in her own head, around early July.

When Jiles heard about the recall soon after, she called Danone Canada, the plant-based milk manufacturer, to find out if their Silk coconut milk was in the contaminated batch. It was, she says.

“My son is very small, he’s very young, so I asked what we do in terms of overall monitoring and she said someone from the company would get in touch within 24 to 48 hours,” Jiles says from a First Nations reserve near Montreal.

“I never got a call back. I never got an email”

At home, her son’s fever broke after three days, but gas pains stuck with him, she says. It took a couple weeks for him to get back to normal.

“In hindsight, I should have taken him (to the hospital) but we just tried to see if we could nurse him at home because wait times are pretty extreme,” Jiles says, “and I don’t have child care at the moment.”

Joseph Desmond, 50, Sydney, N.S.

Joseph Desmond says he suffered a seizure and fell off his sofa on July 9. He went to the emergency room, where they ran an electroencephalogram (EEG) test, and then returned home. Within hours, he had a second seizure and went back to hospital.

His third seizure happened the next morning while walking to the nurse’s station.

In severe cases of listeriosis, bacteria can spread to the central nervous system and cause seizures, according to Health Canada.

“The last two months have really been a nightmare,” says Desmond, who has joined the proposed lawsuit.

When he returned home from the hospital, his daughter took a carton of Silk dark chocolate almond milk out of the fridge and asked if he had heard about the recall. By that point, Desmond says he was on his second two-litre carton after finishing the first in June.

“It was pretty scary. Terrifying. I honestly thought I was going to die.”

Cheryl McCombe, 63, Haliburton, Ont.

The morning after suffering a second episode of vomiting, feverish sweats and diarrhea in the middle of the night in early July, Cheryl McCombe scrolled through the news on her phone and came across the recall.

A few years earlier, McCombe says she started drinking plant-based milks because it seemed like a healthier choice to splash in her morning coffee. On June 30, she bought two cartons of Silk cashew almond milk.

“It was on the (recall) list. I thought, ‘Oh my God, I got listeria,’” McCombe says. She called her doctor’s office and visited an urgent care clinic hoping to get tested and confirm her suspicion, but she says, “I was basically shut down at the door.”

Public Health Ontario does not recommend listeria testing for infected individuals with mild symptoms unless they are at risk of developing severe illness, such as people who are immunocompromised, elderly, pregnant or newborn.

“No wonder they couldn’t connect the dots,” she adds, referencing that it took close to a year for public health officials to find the source of the outbreak.

“I am a woman in my 60s and sometimes these signs are of, you know, when you’re vomiting and things like that, it can be a sign in women of a bigger issue,” McCombe says. She was seeking confirmation that wasn’t the case.

Disappointed, with her stomach still feeling off, she says she decided to boost her gut health with probiotics. After a couple weeks she started to feel like herself.

But since then, McCombe says, “I’m back on Kawartha Dairy cream in my coffee.”

B.C. mayors seek ‘immediate action’ from federal government on mental health crisis

Published

 on

 

VANCOUVER – Mayors and other leaders from several British Columbia communities say the provincial and federal governments need to take “immediate action” to tackle mental health and public safety issues that have reached crisis levels.

Vancouver Mayor Ken Sim says it’s become “abundantly clear” that mental health and addiction issues and public safety have caused crises that are “gripping” Vancouver, and he and other politicians, First Nations leaders and law enforcement officials are pleading for federal and provincial help.

In a letter to Prime Minister Justin Trudeau and Premier David Eby, mayors say there are “three critical fronts” that require action including “mandatory care” for people with severe mental health and addiction issues.

The letter says senior governments also need to bring in “meaningful bail reform” for repeat offenders, and the federal government must improve policing at Metro Vancouver ports to stop illicit drugs from coming in and stolen vehicles from being exported.

Sim says the “current system” has failed British Columbians, and the number of people dealing with severe mental health and addiction issues due to lack of proper care has “reached a critical point.”

Vancouver Police Chief Adam Palmer says repeat violent offenders are too often released on bail due to a “revolving door of justice,” and a new approach is needed to deal with mentally ill people who “pose a serious and immediate danger to themselves and others.”
