The Invention of the Menstrual Cup

The Invention of the Menstrual Cup

1 day ago
The menstrual cup has transformed period management, offering a comfortable, effective, and eco-friendly alternative to traditional products. Originally created in the 1930s by Dr. Earle Haas as a solution to the limitations of menstrual products, the cup has evolved from its early rubber design to today’s high-quality, medical-grade silicone models. With growing awareness about sustainability, reusable menstrual cups have become increasingly popular since the 2000s, offering up to 12 hours of leak-free protection. This innovation has empowered individuals to experience a more convenient, cost-effective, and environmentally friendly approach to menstrual hygiene.

Understanding Period Poverty

Understanding Period Poverty

8 days ago
Period poverty is a global issue impacting millions of individuals who cannot afford or access basic menstrual products, leading to severe consequences for their health, education, and economic prospects. This silent crisis often results in poor hygiene, social stigma, missed school or work, and mental health challenges. The effects ripple beyond individuals, affecting entire communities and economies through reduced productivity and participation. Solutions to combat period poverty include raising awareness, promoting affordable products, advocating for government support, initiating community programs, and pushing for policy changes to ensure that everyone has access to essential menstrual products. Addressing period poverty is crucial to fostering a more inclusive and equitable world.

Breast Cancer Prevention

Breast Cancer Prevention

14 days ago
To reduce the risk of breast cancer, adopting healthy lifestyle choices and eating specific foods can make a significant difference. Incorporating leafy greens, berries, cruciferous vegetables, flaxseeds, and fatty fish into your diet provides antioxidants and anti-inflammatory benefits. Daily habits like staying hydrated, exercising regularly, getting enough sleep, managing stress, and limiting processed foods also help lower breast cancer risk. Additional steps such as breastfeeding, maintaining a healthy weight, and avoiding hormone-disrupting chemicals like BPA and parabens can further reduce risk. Small, consistent changes to your diet and habits can lead to long-term wellness benefits.

Testimonials

Michelle H.

Second pair I've bought! It did not fail me this time either. I did not feel gross wearing them at work and honestly hate having to put on a pad to wash them. These are awesome. They shipped them the same day I bought them and I will be buying a third pair whenever I can!

Shasha M.

I have nothing but good things to say. now I have several versions form Heralogie and cannot decide which I like best. The bikini is sexy but for tight pants would recommend a full panty which will not show

Andrea M.

These underwear are amazing! I have a heavy flow and these are truly magical. I wore them just as is and did not have to think about staining or changing a pad/tampon. If you are interested in sustainable period care, get them now!!!

Karissa W.

I've been looking for period undies for a while, and these are so worth it! These look the same and seem to work the same as the most popular period underwear brand. The price on these are a huge bonus, I hate how other brands increase price based on absorbency. I love the inclusivity, too!
