Clue releases Our Year in Cycles, an annual snapshot of hormones and health, with the aim of tackling taboo and stigma around the menstruation conversation
November 24, 2025 - New York - 24 November 2025 - London - . Clue, the #1 women-led period and cycle tracker, trusted by over 100 million worldwide, has today released Our Year In Cycles - an annual analysis of how women and people with cycles tracked their lives, bodies and emotions throughout 2025.
Based on hundreds of millions of anonymised logs made in the Clue app, this year’s edition breaks down the real rhythms behind our moods, cravings, orgasms, sleep (or lack of it), politics-fuelled stress, and the 280 million days we collectively spent bleeding—the equivalent of one person experiencing nearly 767,000 years of periods.
"Menstrual health affects over half the population, yet the cultural taboo around it has left generations without the knowledge or support they deserve," commented Rhiannon White, CEO of Clue.
"Our Year In Cycles reveals how profoundly our hormonal patterns intersect with our daily lives, bringing what has been hidden into the light—not to sensationalise it, but to normalise it. By transforming millions of lived experiences into clear, accessible insights, Our Year In Cycles makes it possible for all of us to talk about hormones, pain, pleasure and wellbeing with the same openness we bring to other life topics."
From the 280 million days of bleeding tracked to the 44.6 million days of cramps logged, Our Year in Cycles demonstrates the world’s emotional and hormonal highs and lows through the bodies of millions of women and people with cycles.
Key global insights from Your Year in Cycles
Ringing in the New Year with sex and fantasies
New Year’s Day came in hot—literally. It was the single most popular day of 2025 for high sex drive, sex, orgasms, and fantasies, suggesting that Clue users kicked off the year with a surge of intimacy.
Whether it’s the psychological clean-slate effect, post-party closeness, or simply having a rare moment of rest and privacy, the data shows that January 1st isn’t just for resolutions.
On the flip side, September 10th was reported as a global ‘not tonight’ moment, as the day we tracked the lowest libido.
Gen Z leads the pleasure revolution
Half of all tracked orgasms in 2025 came from 18- to 24-year-olds, making Gen Z the most vocal (and possibly the most self-aware) generation when it comes to pleasure.
Meanwhile, orgasm tracking drops sharply with age, with only 2% coming from people aged over 45.
Data also shows that the youngest adults are those rewriting the script, turning pleasure stigma into pleasure literacy. When it comes to masturbation, Gen Z accounted for more than half (58%) of all entries, with this same age group also logging the most sex toy use (44%) over any other demographic.
But pleasure isn’t logged as often as sex
Clue users logged 34 million sex sessions and 4.4 million orgasms. The data highlights a simple truth: pleasure is still under-tracked and under-discussed compared with sex itself, revealing how deeply the pleasure gap is embedded in culture.
Meanwhile, the Philippines, Peru, and Ukraine topped both the "most sex" and "most orgasms" lists, sparking new cultural questions about geographical intimacy.
Traditional period products still dominate despite growing appetite for reusable methods
Despite the hype around reusable period products, 2025 was still the year of the pad, used by nearly two-thirds of Clue users (63%), with tampons used by 14% comparatively.
The data suggests that real-life period habits aren’t changing as fast as the headlines, with most people sticking with what feels safe, familiar, and reliable.
With rising concerns around tampon ingredients and contamination making global news, it’s clear that trust, not trends, is driving product choices, and the shift toward reusables is more a slow evolution than a sudden revolution.
Period pain remains one of the most universal (and sadly, normalized) experiences
Clue users logged a staggering 44.6 million days of cramps, the equivalent of 122,000 years of pain if shouldered by one person.
Cramps were the most common pain logged (35%), followed by breast tenderness (12%), lower back pain (11%) and headaches (10%). Almost one in five cramps (19%) were rated severe.
The key takeaway? Menstrual pain isn’t minor; it’s massively under-recognized, and it’s time the world treated it with the seriousness it deserves.
Hormones and days of the week shaped our emotional landscape - and surprisingly, politics didn’t help
Mood changes topped the charts over the past year, accounting for almost a fifth (17%) of all tracked feelings. The emotional peak of the year was revealed as the day after the 2024 US presidential elections, when users worldwide recorded their saddest, angriest, and most stressed moods.
Weekly patterns painted a familiar yet striking picture: Mondays are (unsurprisingly) the gloomiest, Thursdays the most stressful, Saturdays the happiest, most energized, and most creative, and Sundays the most popular day for sex.
So much for a day of rest.
Sleep was scarce, with over a third waking up tired
Across millions of sleep logs, 38% recorded waking up tired, 15% struggled to fall asleep, 14% slept restlessly, and 10% experienced vivid dreams—perhaps hormones, stress, and modern life are a recipe for a global sleep deficit?
The good news? We’re proactive about our reproductive health
Nearly a quarter of a million OBGYN appointments were recorded throughout the year, with 18- 34-year-olds making up 84% of all appointments, suggesting that younger adults are more in tune with their health, or simply navigating more reproductive health milestones.
Similarly, 18- 34-year-olds accounted for 90% of all STI screenings logged—a strong sign that stigma is decreasing and sexual health checks are becoming more routine.
Dr Charis Chambers, The Period Doctor and Chief Medical Officer at Clue, shared her view on the data: "When millions of people track their cycles, we gain a clearer picture of how hormones influence sleep, mood, energy, sex and pain. Our Year in Cycles isn’t just about periods; it’s about connecting the dots between our bodies and the experiences that are so often dismissed or stigmatised. Severe cramps, mood shifts, low energy, and disrupted sleep are deeply common and valid. By representing real people with real data, we can help reduce shame and stigma around the menstrual health conversation."
Clue’s data shows that cycles aren’t just about periods—they shape moods, sleep, cravings, intimacy, pain, and the rhythms of daily life. From the highs of orgasms and creativity to the lows of cramps and sleepless nights, the data turns millions of personal experiences into a collective story.
By making the invisible visible, Clue is helping to normalise conversation, break taboos, and empower women and people with cycles to understand, care for, and celebrate their bodies - every single day of the year.
