What’s making the news in women’s health
The hidden curfew: More than half of women feel unsafe exercising after dark
More than half of British women feel unsafe exercising outdoors alone after dark, according to new research highlighting how fears of harassment and violence are restricting women’s freedom to be physically active. A survey commissioned by Sport England’s This Girl Can campaign reveals that women’s safety concerns are growing, with many changing their exercise routines or abandoning outdoor activity altogether as winter approaches.
Women feel significantly less safe than men. Some 55% of women report feeling unsafe exercising outdoors alone after dark, compared with 33% of men. Nearly seven in ten women (69%) worry about sexual harassment or intimidation, up from 60% in 2023, while 52% fear being followed.
Safety concerns directly affect exercise habits. As daylight hours shorten, 34% of women say they will change their outdoor exercise routines, 24% will avoid exercising alone, and 11% will share their location before heading out. Women are more than three times as likely as men to stop exercising outdoors entirely after dark.
These fears reflect wider concerns about women’s safety. Among the 1,000 women surveyed, 67% believe exercising outdoors has become less safe, while more than two-thirds think rising online misogyny and anti-women attitudes have contributed to women feeling less secure.
Sport England’s Let’s Lift the Curfew campaign, now in its fourth year, seeks to highlight the restrictions women face and encourage action to make outdoor exercise safer and more accessible. Advocates argue that responsibility should not fall solely on women to change their behaviour, but on communities and policymakers to create safer environments.
The takeaway: The findings highlight an often-overlooked structural barrier to women’s health: the unequal freedom to be physically active, particularly after dark. While much of the research and social conversation about women’s exercise and health focus on what kinds of exercise women should do and how often, their ability to do so is often shaped by whether they feel safe in public spaces.
A new approach to women’s heart health, from puberty to menopause and beyond
Four major U.S. medical organizations have introduced a new framework recognizing that women’s cardiovascular health is shaped by hormonal and reproductive changes across the lifespan. The landmark guidance calls for heart disease prevention to begin much earlier, integrating cardiovascular risk assessment into routine women’s healthcare rather than treating heart health as a separate concern.
Developed jointly by the American Heart Association, American Academy of Pediatrics, American College of Obstetricians and Gynecologists, and Society for Maternal-Fetal Medicine, the framework identifies four distinct stages of women’s cardiovascular health: puberty, reproductive years, perimenopause and post-menopause. Each stage presents different hormonal, metabolic and cardiovascular considerations.
Reproductive health can provide early warning signs of heart disease. Conditions such as PMOS (formerly PCOS), early onset of menstruation, and irregular menstrual cycles can signal increased cardiovascular risk years before conventional risk factors become apparent. The framework encourages clinicians to recognize these reproductive indicators as potentially important information about a woman’s long-term heart health.
Pregnancy and menopause are particularly important windows for prevention. Pregnancy is recognized as a cardiovascular stress test, with complications such as preeclampsia, gestational diabetes and preterm birth associated with increased future cardiovascular risk. During perimenopause, changes in cholesterol, blood pressure and metabolic health can further alter risk, making proactive screening and prevention particularly important.
The goal is more integrated, preventive healthcare. Cardiovascular disease remains the leading cause of death among women in the U.S., along with many other countries. By establishing a shared framework for pediatricians, gynecologists, obstetricians and cardiologists, the guidance aims to reduce fragmented care, identify risks earlier and ensure that reproductive health information informs cardiovascular prevention.
The takeaway: This new framework represents an important shift in thinking around identifying and managing cardiovascular risk. It moves towards an integrated and lifelong approach to prevention that recognizes the role of reproductive and hormonal health and the connections between events and conditions experienced from adolescence through menopause and future cardiovascular risk. It is precisely the kind of integrated approach we need more of in women’s health.

New research sheds light on why IBS is more common in women
Recent research published in Science has identified a biological mechanism that may help explain why irritable bowel syndrome (IBS) affects women at roughly twice the rate of men. In experiments with mice, researchers found that estrogen increases sensitivity to pain in the gut by activating a signalling pathway involving intestinal cells, gut bacteria and the nervous system. Specifically, estrogen makes certain intestinal cells more responsive to acetate, a substance produced by gut bacteria, triggering a chain of reactions that increases serotonin release and amplifies pain signals. The findings suggest that hormonal fluctuations, alongside factors such as diet and stress, may contribute to the heightened gut sensitivity experienced by women with IBS. They also offer a potential biological explanation for why IBS symptoms can fluctuate with the menstrual cycle and why dietary interventions, such as a low-FODMAP diet, may help some patients. Although the findings have yet to be confirmed in humans, they provide important evidence of how estrogen, gut bacteria and the nervous system interact to influence digestive pain, potentially paving the way for more targeted IBS treatments.

Why making friends as an adult is so hard, and how to find your people, with Dr Natalie Hutchins and Yvonne Richter
Loneliness is just as common among women as men, yet women’s experiences often go unrecognized, compounded by social expectations that women should naturally excel at forming and maintaining friendships. In this episode of How to Be a Woman, Dr Natalie Hutchins speaks with psychotherapist Yvonne Richter about why adult friendships can be difficult to establish, particularly during major life transitions such as motherhood, moving abroad and midlife. They explore how attachment styles, shifting identities, envy and unrealistic expectations of friendship can contribute to loneliness, even when women are surrounded by other people. While much of the conversation focuses on the particular challenges of building friendships and navigating loneliness when living abroad, many of the issues they discuss will resonate with women regardless of where they live, especially as friendships evolve with age and changing circumstances. Their advice is both practical and reassuring: meaningful friendships take time, vulnerability and initiative, and building connections often starts with small steps, such as turning a casual acquaintance into a friendship through repeated invitations and shared experiences.

A promising new approach to women’s cancer screening in Africa
The World Health Organization (WHO) has highlighted progress in a new initiative aimed at improving early detection of breast and cervical cancer in Côte d’Ivoire, Kenya and Zimbabwe, where late diagnosis and limited access to care contribute to high cancer mortality among women. The Women’s Integrated Cancer Services (WICS) programme brings breast and cervical cancer screening into existing primary healthcare facilities, alongside checks for hypertension, diabetes and mental health conditions, making preventive care more accessible and comprehensive. Early progress includes integrated screening services in Côte d’Ivoire, digital monitoring systems in Kenya and the selection of participating health centres in Zimbabwe. The initiative represents a promising shift toward more coordinated, whole-person healthcare for women.
