    How to Build Strong Adult Friendships That Last | #6 with Dr. Jaimie Krems

    Why is making friends as an adult so difficult—and why are female friendships often both deeply supportive and unexpectedly complicated? Friendship may be one of the most overlooked public health assets we have. Yet it's also one of the least studied areas of psychology. In this episode, Dr. Sarah Hill sits down with UCLA friendship researcher Dr. Jaimie Krems to unpack the science behind why friendships matter, why women experience friendship differently than men, and what we can do to build stronger, healthier connections in modern life. Why Are We Living Through a Friendship Recession?Dr. Jaimie Krems is a social and evolutionary psychologist at UCLA, where she directs the Social Minds Lab and the UCLA Center for Friendship Research. Her work explores one of the most important yet overlooked questions in psychology: why humans make friends, how friendships evolve, and why they profoundly shape our physical and mental health. Together, Dr. Sarah Hill and Dr. Krems explore how friendship protects us against anxiety, depression, cardiovascular disease, and even premature death. They discuss why lacking close friends can have health consequences comparable to smoking 15 cigarettes per day, and why researchers now consider friendship a major public health issue. The conversation also dives into what many women secretly experience but rarely discuss: why female friendships can feel both extraordinary and emotionally complicated. Can You Actually Make Friends as an Adult?The answer is yes—but it requires intentionality. In a culture optimized for convenience and productivity, we've accidentally eliminated many of the moments that once helped friendships grow naturally. This episode offers practical ways to bring those moments back. KEY TAKEAWAYSStrong friendships improve mental health, cardiovascular health, and longevity.Friendship is one of the strongest predictors of happiness across adulthood.Repeated interactions are one of the simplest ways to build meaningful adult friendships.Technology has unintentionally removed many opportunities that once helped friendships deepen naturally.Women often prioritize fewer, deeper friendships, while men tend to maintain larger social networks.Friendship deserves the same intentional investment we typically give to careers and romantic relationships.

    Female Pleasure, Explained | #5 with Dr. Cindy Meston

    Female sexuality is far more complex and fascinating than we’ve been taught. In this episode of The XX Lab with Sarah Hill, Sarah sits down with pioneering sexuality researcher Dr. Cindy Meston to unpack the science of female desire, arousal, orgasm, menopause, antidepressants, birth control, and the psychology behind what actually creates satisfying sex for women. From groundbreaking lab research measuring physiological arousal to redefining female orgasm for the World Health Organization, Dr. Meston shares decades of discoveries that challenge outdated assumptions about women’s sexuality and reveal just how much context, emotion, hormones, stress, and self-perception shape desire. In this conversation, they explore: Why women’s desire works differently than men’sHow stress, exercise, and novelty can increase arousalThe hidden sexual side effects of hormonal birth control and antidepressantsWhy orgasm becomes easier for many women with age and experienceHow sexual schemas and body image influence intimacy across the lifespan This episode is science-driven, deeply validating, and packed with insights every woman should hear. If you’ve ever wondered whether your experience is “normal,” this conversation will completely change the way you think about sex, desire, and pleasure. About this guest: Dr. CINDY M.

Her book Why Women Have Sex (co-authored with Dr. David Buss) has been translated into twelve languages and has received extensive media coverage.

    Your Fertility Isn’t Just About Age  | #4 with Dr. Natalie Crawford

    What if infertility is not just about getting pregnant, but one of the earliest warning signs that something deeper is happening in the body? In this episode of The XX Lab with Dr. Sarah Hill, Sarah sits down with double-board certified fertility specialist Dr. Natalie Crawford to unpack the science of ovulation, egg quality, chronic inflammation, stress, PCOS, endometriosis, and the hidden factors affecting women’s reproductive health. Together, they challenge the outdated idea that fertility only matters once you’re trying to conceive and explain why your menstrual cycle may be one of the most important indicators of overall health.

In this episode: Why regular periods do not always mean healthy ovulationHow stress and inflammation can interfere with fertilityThe truth about egg quality, aging, and fertility testingWhy endometriosis is still so underdiagnosedWhat women can actually do to support fertility naturally Whether you want children someday or simply want to better understand your body, this conversation will change the way you think about reproductive health.
