The Hidden Hormone Disruptors in Everyday Life

We usually think about hormones as something our bodies produce internally.

But our endocrine system can also be influenced by substances in the world around us.

Some are known as endocrine-disrupting chemicals, or EDCs.

What are endocrine disruptors?

EDCs are substances that can interfere with the body’s hormonal signaling.

Some can mimic the activity of naturally occurring hormones, including estrogen. Others may block hormone receptors or alter how hormones are produced, transported, or broken down.

Chemicals with estrogen-like activity are sometimes called xenoestrogens.

Researchers have identified potential endocrine-disrupting substances in everyday products, including certain plastics, pesticides, cosmetics, fragrances, and household materials.

Does exposure mean your hormones are imbalanced?

Not necessarily.

Scientists continue to investigate how different chemicals affect human health, including the importance of exposure levels, timing, duration, and individual susceptibility.

There is evidence linking some endocrine-disrupting chemicals with reproductive and metabolic health concerns. But it’s an oversimplification to assume everyday chemical exposure is the explanation for common hormonal symptoms.

Small changes that can reduce exposure

You don’t need to replace everything in your home overnight. Consider a few practical swaps:

  • Store and reheat food in glass or other food-safe containers instead of heating it in plastic.
  • Reduce unnecessary fragrance exposure where practical.
  • Wash fresh produce thoroughly.
  • Choose personal care and household products with ingredient information you’re comfortable with.

These steps won’t guarantee better hormone levels, but they can help reduce exposure to certain substances.

Knowledge, not fear

Understanding environmental influences is one part of understanding hormonal health.

And it’s worth remembering that hormones are affected by far more than what we put on our skin or store our food in.

Our internal systems play an important role, too.

Shilpi Shares Her Entrepreneurial Journey with Harvard Women in Entrepreneurship

Qyn Labs founder and CEO Shilpi Gupta recently joined Harvard Women in Entrepreneurship for an inspiring conversation about building a deep tech company, putting customers first, and creating meaningful change through innovation.

What began as an opportunity to share Qyn's mission and the journey behind building a new approach to hormone health became a thoughtful exchange with the next generation of women entrepreneurs.

The students brought ambitious ideas, insightful questions, and a clear understanding of the problems they hope to solve. Their curiosity and enthusiasm reinforced an important belief: entrepreneurship isn't defined by a perfect résumé or a traditional path. It's driven by the willingness to ask difficult questions, challenge existing approaches, and build solutions that make a meaningful difference.

Throughout the conversation, Shilpi shared several lessons from her own entrepreneurial journey and the experience of building Qyn.

You Don't Need a Perfect Résumé to Build a Deep Tech Company

Building a deep tech company requires curiosity, persistence, and a willingness to understand a problem at every level.

While experience can be valuable, it isn't the only path to innovation. Sometimes, approaching an established industry with a fresh perspective allows entrepreneurs to recognize opportunities that others have overlooked.

For aspiring founders, Shilpi emphasized the importance of understanding the layers of the problem they're trying to solve and remaining curious enough to keep learning.

You don't need to have every answer before you begin. You need to be willing to ask questions, seek expertise, and continue learning as you build.

Be Obsessed with the Customer, Not Just the Technology

Technology should exist to solve a real problem.

At Qyn, that principle guides the development of an at-home, blood-based hormone measurement system designed to help women better understand how their hormone levels change over time.

For a woman navigating perimenopause, menopause, or hormone therapy, the goal isn't simply to have access to another piece of technology or another health metric.

She wants to understand what's happening in her body, how her hormones are changing, and what those changes might mean for her individual experience.

By keeping the needs of women at the center of product development, Qyn is working to bridge the gap between isolated hormone measurements and a more personalized understanding of hormone health.

It's a reminder that innovation begins with listening to the people you're building for.

Credibility Is Earned, Not Marketed

Trust is essential when building a product that people may rely on to better understand their health.

For Shilpi, credibility comes from demonstrating real results, being transparent about what a technology can and cannot do, and showing people how their personal health information will be protected.

As Qyn continues to develop its technology, these principles remain central to the company's approach.

Building trust requires more than communicating a compelling vision. It means doing the work to support that vision through science, responsible product development, and a commitment to the people the technology is intended to serve.

Build Something You Believe In

Shilpi also encouraged the students to think deeply about what motivates them to become entrepreneurs.

Her own experiences inspired her to question why women have historically had such limited visibility into their changing hormone levels and what could be possible if hormone measurement became more accessible.

That personal connection helped inspire the creation of Qyn.

But she emphasized that founders don't necessarily need to have experienced a problem themselves to build a meaningful solution.

What matters is finding a problem they genuinely care about solving and being honest about their motivation for pursuing it.

Entrepreneurship requires persistence, especially when building something new. Having a meaningful connection to the work can help sustain that commitment through the inevitable challenges of bringing an idea to life.

Looking Ahead to the Next Generation of Women Entrepreneurs

The conversation at Harvard was an opportunity to share the Qyn story, but it was also a reminder of the extraordinary potential of the next generation of women founders.

Their ambition, curiosity, and thoughtful questions reflect a future in which more women are not only participating in innovation but helping define the problems worth solving.

A special thank you to the Harvard Women in Entrepreneurship board for hosting Shilpi and to every student who participated in the conversation and stayed afterward to continue asking questions.

We look forward to seeing what you build.

Inside Qyn: Building Hormone Intelligence at the Intersection of Science and AI

What does it actually take to build a new way of measuring and understanding hormones?

‍

Qyn founder and CEO Shilpi Gupta sat down with Matt Crane on The Lantern at the Wyss Institute at Harvard University to talk about what’s happening behind the scenes at Qyn — from the science of at-home blood-based hormone measurement to the intelligence layer designed to connect hormone trends with signals people are already tracking through their wearables.

‍

It’s also a conversation about building deep technology itself. Shilpi discusses why getting the underlying measurement right has to come before adding AI, what the team has learned while developing Qyn, and why creating something new in health requires both speed and scientific rigor.

‍

For anyone curious about not only what Qyn is building, but how we’re building it, this is a closer look inside the work.
