What happens if you get your period in space? This is a question that scientists at a research group called AstroCup set out to explore. In 2022, they launched two menstrual cups on a rocket to test how well they handle space conditions.
The cups, made by Lunette, went up for about 9 minutes, reaching an altitude of 1.9 miles (3 kilometers). During this time, they faced vibrations and pressures typical of space travel. Researchers conducted leak tests with water and glycerol after the flight and found that the cups remained intact, showing no damage or degradation. These results were recently shared in the journal NPJ Women’s Health.
Menstrual cups are making waves as a sustainable alternative to single-use products like pads and tampons. With the ability to last for years, they are not just eco-friendly but also practical for future space missions. While many astronauts currently choose to pause their menstrual cycles using hormonal methods, this may not always be feasible, especially during longer missions where managing waste becomes challenging.
The AstroCup team believes menstrual cups could be a key solution for future space health needs. Yet, more research is needed. Understanding how these cups perform in reduced gravity and over longer missions could provide valuable insights. The research team hopes to test various menstrual products aboard the International Space Station.
Dr. Lígia Coelho, the lead researcher, emphasized the importance of exploring health autonomy in space. She noted that offering a range of options empowers women astronauts, allowing them to choose based on their preferences or health needs.
Interestingly, women on Earth often use hormonal contraceptives to control their periods. This method is generally safe and can help reduce period symptoms. However, the implications of using these methods in space need further study, especially regarding potential side effects like blood clotting.
As journeys to the Moon and Mars become more plausible, understanding menstrual health in space will be crucial for reproduction and overall well-being. Researchers are keen to ensure that women astronauts can manage their health effectively on longer missions, respecting their autonomy and preferences.
While the concept of reproduction in space may still seem distant, effective menstrual management will play a vital role in making this a reality. With space exploration evolving, it’s essential to recognize and adapt to the diverse health needs of all astronauts. The research offers a promising glimpse into the future of women’s health in the cosmos.
