Your sister's postpartum mental health could affect yours—here's what new research reveals
When I had my second baby, I invited my sister, who at the time was living nearby—to attend the birth. My first labor and delivery had been such a shock, that I felt it was important to share the birth experience with her, so she'd be less in the dark if she one day had kids. She remains grateful for that precious experience we shared.
Turns out, sisters share a lot.
If you're pregnant or thinking about having a baby, you've probably heard of postpartum depression (PPD). But there's another, rarer postpartum mental health condition that deserves more attention: postpartum psychosis. And according to a new study published in the American Journal of Psychiatry, your sibling's experience with it could be more relevant to your own mental health than you might expect.
Researchers at Mount Sinai examined over 1.6 million women using Swedish national health records and uncovered a startling statistic: If your sister had postpartum psychosis, your own risk increases tenfold. That number rises to 14 times higher if she also has a diagnosis of bipolar disorder. You can read the study here: American Journal of Psychiatry and coverage from Neuroscience News.
Let's pause here. That relative risk sounds terrifying—but what does it really mean?
While a tenfold increase sounds massive, it's important to understand that the absolute risk of postpartum psychosis remains low: about 1.6%. That nuance matters. This is not about panic. it's about being prepared.
'Every woman of childbearing age and their physicians need to know about the existence of, severity, symptoms, and familial risk for postpartum psychosis so it can be promptly diagnosed and, hopefully, prevented,' said Dr. Veerle Bergink, Director of the Women's Mental Health Center at Mount Sinai and co-senior author of the study.
Here's why this research matters for moms—and for sisters.

This isn't the baby blues, and it's not the same as PPD. Postpartum psychosis is a severe psychiatric emergency. It often appears within days to weeks after childbirth and can include:
Hallucinations
Delusions
Paranoia
Insomnia
Rapid mood swings
Disorganized thinking
Suicidal thoughts or thoughts of harming the baby
These symptoms can be terrifying—and potentially life-threatening—if left untreated.
If your sister experienced postpartum psychosis, talk to your provider as early as possible in your pregnancy, or even before you conceive. You might benefit from closer monitoring, earlier mental health screenings, and a tailored postpartum support plan.
Preventive steps could include:
Building a mental health care team before delivery
Arranging postpartum support (think night doulas, therapist check-ins, or medication plans if appropriate)
Involving partners, family, or close friends in awareness of early symptoms
Avoiding sleep deprivation, a common trigger, through shared caregiving
Knowledge is power—but only if we act on it.
Too often, maternal mental health risks fly under the radar, especially rare ones like postpartum psychosis. And when risks aren't well known, moms suffer in silence. This study offers an opportunity to change that by building systems of support and awareness before a crisis hits.
As Dr. Bergink put it:
'Too many women at higher risk don't know it—and are left on their own with a new baby and no support.'
And that's a systemic failure—not a personal one. It's the result of a healthcare culture that still doesn't treat maternal mental health as central to maternal health. We deserve better.
So if you're pregnant or postpartum, or supporting someone who is, and you know there's a family history, bring it up. Advocate for a plan. Make space for mental health in your birth and parenting journey.
Because when moms are supported, everyone wins.

Why More Young People Are Becoming 'Relationship Anarchists'
Jun 5, 2025 3:51 AM A growing segment of millennials and Gen Z are forming 'anti-hierarchal' relationships with multiple partners and friends, according to a new study by the dating app Feeld. Photo-Illustration:'People are sick of the rules of society,' Lavvynder says over the phone from their home in Salt Lake City on a recent Monday afternoon. 'Monogamy has become the default. Straight cis gender patriarchy is the default. A lot of us want to do things our own way—not have a government or religion tell us what to do.' I had asked Lavvynder, 30, who is trans nonbinary and practices polyamory, why they think 'relationship anarchy'—an egalitarian philosophy and approach to dating—is getting more popular among young people. According to a new study conducted by the dating app Feeld and sex educator Ruby Rare, author of The Non-Monogamy Playbook , relationship anarchy is on the rise among millennials and Gen Z as a remedy to the loneliness epidemic. Relationship anarchy (RA) is a relationship philosophy built around clear values: it is anti-hierarchal, anti-capitalist, prioritizes mutual care, and is all about cultivating relationships based on consent. The term, according to Feeld, was coined in 2006 by Swedish writer and activist Andie Nordgren, who said in her manifesto, relationship anarchy 'questions the idea that love is a limited resource that can only be real if restricted to a couple.' Though the lifestyle has quietly emerged as a prevailing relationship framework among communes in San Francisco and across Europe in the last decade, it is again finding a wider audience in our current era of romantic upheaval, where young people are staying single for longer, and polyamory has become far more common. According to the Feeld study, one in five people practice it unknowingly, and 36 percent of 25 to 36 year olds have adopted the lifestyle, compared to 15 percent of Boomers. Lavvynder was in a vulnerable but curious space, separated from their partner of two years, when they stumbled on a friend's Instagram story about relationship anarchy in 2023. The software project manager had no previous experience with it but felt drawn to its possibilities. 'I also familiarized myself with the Relationship Anarchy Smorgasbord,' a worksheet that helps people set terms for how to define an anarchist relationship unique to their circumstance,' Lavvynder says. 'It's about asking, 'What are the things that we want to be involved in this relationship and what are we gonna agree is part of this relationship? Are we interested in being creative partners? Are we interested in being sexual partners?'' Since then they have fully embraced the lifestyle. We can all agree: dating sucks and has only gotten harder. Forty-seven percent of US adults say dating is more difficult today than it was a decade ago. That has led to a growing interest in alternative lifestyles. According to the Journal of Sex and Martial Therapy , one in five people surveyed in the US and Canada have had experience with non-monogamy. Nontraditional relationships are especially popular among millennials and Gen Z; over 70 percent say they are open to less conventional approaches to partnership, including polyamory and open relationships, according to a study by R29 Intelligence. For relationship anarchists, there is no pecking order among their connections—partners, friends, neighbors, colleagues—are all regarded the same. They treat all their relationships equally, be they romantic or platonic, and believe each relationship possesses 'similar or identical potential for emotional, physical, or mental intimacy, love, and satisfaction,' Rare noted in the study. No one person is given preference over the other. It may seem like relationship anarchy mirrors polyamory but there are fundamental distinctions. Some poly people apply hierarchies to their relationships—'veto power,' as Lavvynder calls it. Relationship anarchists, who can be poly, do not put romantic partners above anyone. 'We're not making rules about other people's relationships. We're just focusing on the connection that we have with that other person.' One misconception about relationship anarchists is that they have perfected relationship dynamics, but that couldn't be further from the truth, Lavvynder adds. 'A lot of people will tell me, 'oh, I wish I could be polyamorous or a relationship anarchist, but I just get too jealous.' And it's like, well, I get jealous too. I'm not void of that emotion. I also experience jealousy. If my partner is talking to somebody new, I feel threatened by that. But the way to deal with that is not to make some rule about how your partner is engaging with other people. It's to figure out what you need to do for yourself,' they say. 'It's really fucking hard, actually.' It's all about shared values, not sexual exclusivity, says Sam, a 33-year-old music licensing administrator in Los Angeles who identifies as gender fluid. Relationship anarchy pushed her to rethink how she defined connection. 'Everyone is taught the rules at a young age: one person in your life is meant to be your everything,' she says, likening it to 'a Disney fairytale romance.' And 'any deviation from that is an offense beyond repair.' People, she says, would feel more fulfilled in their relationships 'if they were able to prioritize others based on what they actually wanted versus what they believe is expected of them.' Sam came to the realization following a breakup. She was 'freshly out as a queer person,' new to nonmonogamy, and in a relationship that encouraged the exploration of her sexual identity. She and her ex were 'swingers ' but Sam says she was 'deeply uncomfortable and unfulfilled' by all the 'casual and often unsatisfying' sexual experiences. When the relationship ended, she dove into the polyamory scene in Los Angeles, where she later learned about relationship anarchy. José Esteban Muñoz, in Cruising Utopia: The Then and There of Queer Futurity , has suggested that 'queerness is a structuring and educated mode of desiring that allows us to see and feel beyond the quagmire of the present.' It comes as no surprise, then, that young people who identify as LGBTQIA+ and also practice ethical nonmonogamy are finding that relationship anarchy is for them. 'We've pushed so many societal norms already and we're in this place where it's like, well, how else can we push this even more?' Lavvynder says. 'It's a function of more and more people coming out as queer and being in queer relationships. They are realizing that there are alternatives to the norm of what love can be,' Jack says. Jack is a 30-year-old physician who identifies as nonbinary. They discovered relationship anarchy during the pandemic. Freed from 'a cycle of serial monogamy,' they say they were introduced to the lifestyle by their current partner, who they live with in Brooklyn, New York. 'We all had so much time to sit and think, and really self-examine. I had time to expose myself to these new ideas. For a lot of people you just don't know what else you can do—until you do. That was certainly the case for me.' Jack and his partner have been together five years. Jack also has three other romantic partners currently—one in San Francisco, another in Asheville, North Carolina and a person they just started seeing in Rhode Island because 'apparently I hate dating people that actually live in the same city as myself.' Above all, Jack says, respect is prioritized in each relationship. Lavvynder, Sam, and Jack requested their last names not be used due to privacy concerns. Still, navigating relationships doesn't come easy. 'It requires a deep level of self reflection, honesty, and communication that we are not taught and is not modeled to us in any traditional societal structures,' Sam says. 'Your boundaries will differ from relationship to relationship.' 'It is difficult and something you have to be conscious of, at least I do,' Jack adds 'I'm not that good at it yet.'

I tried this '5-2-4 fartlek' walking workout for a week — and it's a game-changer
Walking workouts are all the rage at the moment — from silent walking for your mental health, to the military-inspired rucking technique to build muscle. But one form of walking workout making headlines is the Japanese Interval Walking Training (IWT), which promises to burn more fat and lower your blood pressure by alternating your pace. Unlike walking 10,000 steps, this science-based method raises your heart rate and boosts your cardiovascular fitness in less time. This isn't an entirely new phenomenon, however. "Fartlek" walking has been around for a while, and translates to 'speed play' from the native Swedish. It's all about varying the pace and difficulty throughout your walk, mixing intervals of faster-paced walks with slower rambles, allowing you to catch your breath. A study found that alternating periods of brisk and slow walking speeds can improve cardiovascular fitness, boost your overall fitness, and help control blood sugar spikes. Keen to give a new workout a try, I built my own fartlek walking session, and repeated it every morning for seven days. Read on to find out more. Ready to get walking? Here's the workout: Even with the warm-up, this workout took me around 30 minutes every morning. I programmed the workout onto my Apple Watch 10 to avoid having to look at my wrist every few minutes — my watch would buzz when it was time to switch pace. While this workout is suitable for all levels, as you're walking speed will be based on your exertion levels, if you're new to fitness, or you're returning to exercise following an injury or pregnancy, it's always a good idea to speak to your doctor before taking on a new routine. Here's my verdict after a week of walking: Get instant access to breaking news, the hottest reviews, great deals and helpful tips. For those who haven't tried it, the Japanese Interval Walking Training method involves three minutes at a low intensity, then three minutes walking at a high intensity for 30 minutes. This was a slight step up, as the high-intensity part of the workout was longer, and the recovery blocks were shorter. I found that I didn't have long to catch my breath before I was picking up the pace again. I personally loved the extra challenge of walking at a brisk pace for five minutes. I thought about my walking technique — engaging my core so my abs were working, keeping my chest open and shoulders down, and swinging my arms as I moved. If you're new to fartlek walking, or you're getting back into fitness, it might be a good idea to try the three-minute intervals first and build up to five minutes. Like all working parents will appreciate, I have a lot to juggle, and despite writing about fitness for a living, sometimes it's my workouts that suffer. Despite only being 30 minutes long, I felt like I'd worked hard with this interval walk. I'd raised my heart rate higher than I would typically do on a dog walk, and I've found interval walking is a great option for those who want to reap the benefits of walking, without the time to take a longer stroll. Walking can help improve your overall fitness, build muscle, strengthen your bones and joints, and help boost your mood and lower stress. You'll also burn more calories doing a fartlek walk than you typically would walking at the same pace for the same time. If you are walking for weight loss, remember the key is to be in a calorie deficit, burning more calories than you consume. One of the easiest ways to keep an eye on your pace, heart rate, and calorie burn is to strap one of the best fitness trackers to your wrist. I was instantly hooked after a week of the Japanese walking method, and I equally enjoyed this fartlek workout. As a runner, I use my walks as a form of active recovery, but this was a great way to work on my cardiovascular endurance, without the impact of running. It also helped me de-stress and boost my mood, plus, it gave me the excuse to take a break from my laptop and spend 30 minutes outdoors in nature — something we should all do more of. If fitting long workouts into your routine feels overwhelming, this can be done with no equipment, on your lunch break, in your local park or even on the treadmill at the gym. Plus, the joy of fartlek is the freedom to play with your pace — if structured intervals feel too much, just walk faster for two blocks, then slower for a block, or use street lights as your markers. However fast or slow you walk, you're getting fitter and healthier with every step.
