A large-scale social media analysis carried out in Brazil has revealed that public engagement around menstruation is shifting from humour and personal accounts towards themes of social inequality, human rights and public policy. The report, produced by Nexus – Pesquisa e Inteligência de Dados, examined more than 173,000 publications shared between January 2024 and October 2025, accumulating over 12.4 million interactions.

According to Nexus’ Data Intelligence Director, Ana Klarissa Leite e Aguiar, while menstrual pain, pre-menstrual symptoms and lifestyle posts dominated in quantity, it was content discussing poverty, access to sanitary products and workplace policies that drew significantly higher engagement. Only 10.8% of categorised posts addressed political or social aspects of menstruation, yet these generated interactions almost twice as high as casual or comedic conversations online.

This shift coincides with recent public health measures in Brazil, including a national programme supplying sanitary pads to women in vulnerable circumstances. The country is also debating legislation to grant menstrual leave for employees with severe symptoms — discussions that further elevate the topic in digital spaces.

Speaking about the trend, Aguiar highlighted that when menstruation is contextualised through dignity, education, public health or labour rights, audiences respond more actively:
“This indicates that people are not only talking about their daily experiences, but showing a willingness to engage with issues of equity and wellbeing,” she noted.

Online attention reflects public health concerns

Painful menstrual symptoms accounted for 45% of observed posts, followed by gynaecological topics at 20%, and pre-menstrual syndrome at 17%. Alternative hygiene products — including menstrual cups, underwear and discs — were discussed in 12% of posts.

However, the study showed that seemingly rare topics — such as menstruation during humanitarian crises — captured the highest engagement per publication, followed closely by menstrual leave proposals. Nexus’ findings suggest that these complex and socially charged subjects hold stronger narrative influence online compared with informal or humorous content.

For Aguiar, the data shows that the public debate extends far beyond access to sanitary pads: it touches on participation in education, socioeconomic inequality and the fundamental right to hygiene.

Grassroots initiatives meet digital momentum

Amid the growing attention, civil society organisations in Brazil are expanding advocacy efforts. One example is “Fluxo Sem Tabu”, founded in 2020 by Luana Escamilla at just 16 years old. The organisation has reached more than 28,000 women nationwide and now operates with 30 volunteers.

Escamilla stresses that menstrual dignity cannot be reduced to the distribution of pads — it also involves access to toilets, health information and gynaecological services. According to Brazilian public data referenced by the organisation, around 713,000 school-aged girls lack access to a bathroom or shower at home during menstruation, and more than one million students do not have toilet paper available in schools.

Fluxo Sem Tabu combines online education with fieldwork, organising campaigns on menstrual health, access to healthcare services and sports participation. Recent initiatives have supported more than 370 athletes in vulnerable situations with education and hygiene resources.

Towards 2030: dignity as a health mission

The organisation aims to reach 50 million people by 2030 through digital channels and in-person initiatives, reinforcing menstrual education as a component of public health and gender equality.

As online interactions continue to reveal Brazil’s concerns, analysts suggest that social media functions as a “listening instrument”. The data implies that, for many citizens, menstruation is not only a biological process — it is a mirror of wider health inequities and dignity gaps.

Growing engagement around these issues signals increasing societal awareness and strengthens the case for menstrual dignity as a recognised public health priority.
