Despite the improvements to women's rights over the years, female reproductive issues continue to be a touchy subject for many, with a particular taboo around periods.

A workshop on sustainable menstruation is set to be held online tomorrow, organised by the international groups Bleed Red Go Green, Eco Femme and Plastic Free July.

While the workshop aims to improve the environmental and health impacts of sanitary products, the push to normalise the topic was also an important factor, according to a women's health expert in Wagga.

Wagga Women's Heath Centre's Claire Kendall said the issue with menstruation was the notion it needs to be hidden.

"We hide tampons when going to the bathroom, we wear dark clothing in case of leaks, we don't ever proclaim to people in public we have our period and it's just very much not discussed freely," she said.

A big part of removing the stigma was to start calling it exactly what it is: a period.

"Drop the euphemisms, we need to stop joking around with terms like 'Aunt Flow' or 'the red river' and things like that," Ms Kendall said.

"While it is meant as a joke in many cases, we need to normalise the word and stop acting as if it is a secret or something to hide."

The other issue was based around the idea that periods are unsanitary, according to Ms Kendall.

"It doesn't make sense that men continue to be irked or grossed out by women bleeding, when we don't freak out about, say, a man playing footy and getting a bloody nose," she said.

Bleed Red Go Green's Rajasi Kulkarni Diwakar has been at the forefront of changing the way periods are seen in India as a menstrual health management educator.

The workshop, to be held on Sunday, July 26, at 6.30pm AEST, will focus on the ways women can make the switch to reusable sanitary item alternatives.

"There has been a lot of research into the chemicals that are in period pads and tampons, many of which are related to rashes or infections, so the health risks will be one thing covered in the workshop," she said.

"The other factor we address is the ongoing cost associated with disposable products which many women can't afford.

"And finally, we will also look into the environmental impact. There are no real correct disposal mechanisms for sanitary items that are safe and effective, so reducing that waste output via reusable products is a start."

Ms Kulkarni Diwakar said eliminating the taboo around the topic of menstruation was also a vital part of why the workshop was being held.

"If we can talk openly in a safe space, and more scientifically about menstruation, then we can start to break the silence around it," she said.

"But also further than that, once you start speaking about the basics of female reproduction, people feel more comfortable opening up about other important issues like contraception and postpartum depression."

A big part of getting people on board with reusable period products like cloth pads or menstrual cups was removing the idea that it's "gross or unclean", according to Ms Kulkarni Diwakar.

"We often find it gross because we are told to hate our bodies from birth," she said.

"You get told you're too fat, you have the wrong skin colour, you're too short or your breasts aren't big enough, so we are raised with insecurities.

"On top of that, we're led to believe period blood is dirty and so people don't want to deal with it more than they have to by using reusable products that require cleaning.

"Once they see that other women out there are using these items though, and preferring them over disposable alternatives, they start to get on board and wish they'd done it sooner."
