Fathers who take leave beyond ninety days but not too much may have better mental health.
For generations, the story of parental leave has been told almost exclusively through the experience of mothers, leaving fathers as unnamed figures in the margins of the data. A Swedish study of 746 men, published in the American Journal of Public Health, now brings those figures into focus — finding that fathers who take between fourteen and forty weeks of parental leave carry a meaningfully lower risk of depression than those who take only a few weeks. The research does not yet explain why this particular window offers protection, but it asks a question long overdue: what does early fatherhood cost men, and what might shield them from that cost?
- Paternal mental health has been systematically overlooked in parental leave research, leaving a significant blind spot in how societies understand and support new fathers.
- The study found no smooth gradient of benefit — fathers taking five to thirteen weeks showed no significant advantage, suggesting that modest leave may not be enough to shift psychological outcomes.
- Researchers carefully controlled for pre-existing depression and socioeconomic factors, making the protective signal for the fourteen-to-forty-week group harder to dismiss.
- Taking more than forty weeks of leave offered no additional mental health benefit, pointing toward a meaningful upper threshold rather than a simple 'more is better' conclusion.
- The findings land at a moment when policy conversations about parental leave remain largely framed around women, creating an opening to reframe the debate around the wellbeing of both parents.
For decades, research on parental leave has focused almost entirely on mothers — their recovery, their bonding, their mental health. Fathers have remained largely invisible in the data. A new study published in the American Journal of Public Health suggests that invisibility may have obscured something important about how men experience early parenthood.
Swedish researchers followed 746 fathers over eighteen months, tracking depressive symptoms from when their children were nine months old through to twenty-seven months. To account for the possibility that a father's mental state might influence how much leave he chooses to take, the team measured baseline depression at the outset and adjusted their analysis accordingly. Family circumstances and socioeconomic status were also factored in.
The results were specific in a way that resists easy summary. Fathers who took between fourteen and forty weeks of parental leave showed significantly lower rates of depressive symptoms compared to those who took only up to four weeks. Yet the benefit was not linear — fathers taking five to thirteen weeks saw no comparable advantage, and those taking more than forty weeks showed no additional gain. A window, not a slope.
In Sweden, each parent receives ninety nontransferable days of leave — roughly thirteen weeks. The study suggests the mental health benefit emerges when fathers move beyond that baseline, but does not extend indefinitely. The mechanism remains unclear: it may be that this middle range allows genuine presence without the prolonged economic strain of very long absences, or that shorter leaves simply do not provide enough time for the psychological adjustment early fatherhood demands.
What the study makes plain is that fathers, too, experience vulnerability in the early years of parenthood — and that the question of how leave affects their wellbeing deserves the same sustained attention that maternal outcomes have long received.
For decades, researchers studying parental leave have trained their attention almost entirely on mothers—their recovery, their mental health, their ability to bond with newborns. Fathers, by contrast, have been largely invisible in the data. A new study published in the American Journal of Public Health suggests this oversight may have cost us real insight into how men experience early fatherhood and what protections might help them through it.
Swedish researchers followed 746 fathers over eighteen months, beginning when their children were around nine months old. The men answered questions about depressive symptoms at the start of the study and again roughly a year and a half later, when their children had reached twenty-seven months. The researchers also collected detailed information about how much parental leave each father had taken. The design was careful: because a father's existing mental health might influence how much time he chooses to take off work, the team measured baseline depression symptoms at the beginning and adjusted their analysis accordingly. They also accounted for family circumstances, socioeconomic status, and the amount of leave the mother had taken.
The findings were striking in their specificity. Fathers who took between fourteen and forty weeks of parental leave showed significantly lower rates of depressive symptoms than those who took only up to four weeks. The protective effect was real and measurable. But the relationship was not linear. Fathers who took five to thirteen weeks did not show the same mental health benefit, nor did those who took more than forty weeks. There appeared to be a sweet spot—a window where extended time away from work correlated with better psychological outcomes.
In Sweden, each parent receives ninety nontransferable days of parental leave, roughly thirteen weeks. The study's findings suggest that the real mental health benefit emerges when fathers venture beyond that baseline—but not indefinitely. Dr. Michael Wells, one of the study's authors, framed it plainly: fathers who take leave beyond the initial ninety days but stay within about sixty percent of the total available leave appear to experience the strongest mental health gains.
The implications ripple outward. For years, policy discussions around parental leave have centered on women's needs and women's outcomes. This research opens a different conversation: that fathers too experience vulnerability in the early years of parenthood, that time away from work appears to matter for their wellbeing, and that there may be an optimal duration—not too little, not too much, but somewhere in the middle. The study does not explain why this particular window matters most. It could be that fourteen to forty weeks allows fathers to be genuinely present without the psychological strain of extended economic absence. It could be that shorter leaves create stress while longer ones introduce different pressures. The mechanism remains unclear. What is clear is that the question itself—how paternal leave affects fathers' mental health—deserves the same sustained research attention that maternal outcomes have long received.

Why does it matter that we're looking at fathers' mental health now, when we've been studying parental leave for so long?
Because for decades, policy and research have treated fatherhood as secondary to motherhood. We've optimized for women's recovery and bonding, which matters. But we've essentially assumed fathers either don't struggle or that their struggles don't warrant intervention. This study says otherwise.
The finding is oddly specific—fourteen to forty weeks is the sweet spot. Why not more leave?
That's the puzzle. The study doesn't explain it, but you can imagine the tension. More time away from work might create financial anxiety or identity strain. Less time might mean fathers don't actually get to be present enough to experience the psychological benefits of parenting. Somewhere in that middle band, the balance tips.
Did the researchers account for the fact that fathers who take more leave might be different kinds of fathers to begin with?
Yes, that's why they measured depression at the start. They were trying to separate the effect of leave from the effect of who takes it. But you're right to push on it—there's still selection bias baked in. Fathers with more financial security or more supportive employers might take more leave and also have better mental health for other reasons.
So what should a policy maker do with this?
The honest answer is: don't overcorrect. This is one study from Sweden, a country with very different labor and social structures than most places. But it does suggest that somewhere between three and nine months of leave might be a meaningful threshold for paternal mental health. That's worth testing in other contexts.
Does this change how we think about shared parental leave?
It should. If fathers benefit from extended time off, then policies that make that leave genuinely available—not just theoretically—become important. And if there's an optimal window, then policies should be designed to encourage fathers to use it, not just allow it.
