Sleep is something most of us take for granted, until we begin to struggle with it. Whether it’s stress, physical discomfort, a busy lifestyle, or simply the demands of modern living, quality sleep has become increasingly difficult to achieve for many people. Yet science continues to show that good sleep is one of the most important foundations of physical health, emotional wellbeing, and overall quality of life.
For Dr Lynn Barbara, understanding the science behind better sleep became more than just an academic interest. With a PhD in Chemistry and a passion for applying science to real-world challenges, she joined Smart Materials Ltd, where, following the product launch, she transitioned into a commercial role while pursuing an Executive MBA, bridging her scientific background with business development. Her work with Huggah and Zetic® Technology reflects a commitment to combining scientific research with practical solutions designed to enhance sleep quality and everyday comfort.
In this exclusive interview with WHAM we speak to Dr Barbara about her journey as a woman in science, the challenges and opportunities she encountered along the way, and how her scientific expertise led her to rethink one of the most important aspects of our daily lives: sleep.
As more women enter traditionally male-dominated scientific fields, stories like Lynn’s serve as a reminder that innovation often begins with curiosity, persistence, and the courage to challenge conventional thinking. Her journey demonstrates how scientific research can move beyond laboratories and academic journals to create real-world solutions that impact people’s everyday health and wellbeing.
Today, awareness of sleep health is growing rapidly. Researchers continue to uncover links between poor sleep and conditions such as stress, anxiety, cardiovascular disease, reduced immunity, chronic pain, and impaired cognitive performance. At the same time, consumers are becoming increasingly interested in products that can genuinely improve sleep quality rather than simply offer comfort.
This is where science and innovation intersect.
By combining advances in materials science with a deeper understanding of how the body responds during rest, new approaches to sleep technology are emerging. Lynn Barbara’s involvement in the development and scientific evaluation of Huggah and Zetic®. Technology reflects her interest in applying chemistry and materials science to real-world challenges.
In the following interview, we delve into Lynn’s scientific journey, her experiences as a woman in STEM (Science, Technology, Engineering and Mathematics), and the fascinating science behind better sleep.
Can you tell us a little about yourself and what first sparked your interest in chemistry and science?
I was the kid who came home from the beach with pockets full of shells, needing to know what had lived inside each one and why no two were exactly alike. The one who needed to know what clouds were made of, why the sky changed colour at sunset, what was happening inside a seed when it germinated. I could lose hours in a puzzle and genuinely not notice time passing. Curiosity wasn’t something I had. It was just what I was made of.
Becoming a scientist wasn’t something I planned, but that curiosity eventually found its natural home in chemistry, partly thanks to teachers whose enthusiasm made it feel alive rather than abstract. What drew me in was that chemistry sits right at the intersection of fundamental science and the real world. It touches almost everything we encounter, from medicine to the materials around us, and that combination of deep discovery and tangible impact pulled me all the way through a degree and a PhD.
I never grew out of needing to understand why things work the way they do. I just got better tools for finding the answers.
What inspired you to pursue a PhD in Chemistry, and what was that journey like?
I decided to pursue a PhD partly out of genuine passion for research and lab work, and partly out of practicality. Opportunities for R&D in Malta have always been limited, and I was not ready to move abroad. Any scientist here will tell you the same. A PhD felt like the right way to keep doing meaningful scientific work while developing real depth in my field. My research focused on controlling thermal expansion in materials. Many systems fail because materials expand unevenly under heat and finding ways to control that behaviour has applications across aerospace, electronics, biomedical devices, and structural engineering. The work sat at the intersection of crystal engineering and metamaterials, fields that explore how the fundamental structure of a material determines how it behaves in the real world.
A PhD is by nature an independent journey. It is about developing your own thinking, finding your own path through a problem, and building the confidence to trust your own judgement. I found it an incredibly challenging time, both professionally and personally, but it taught me resilience and problem solving in ways I could not have anticipated. By the end I had also realised that academia’s focus on publication output was not what motivated me most. I wanted to apply science in ways that could have a tangible impact on people’s lives, which ultimately led me toward industry and the deep tech startup environment.
As a woman in science, did you face any particular challenges throughout your academic or professional career?
My experience has been largely positive, and I have been fortunate to work with supportive colleagues who value diversity in science. While I have occasionally encountered outdated attitudes, those have been the exception rather than the rule.
One area I continue to work on is confidence, particularly in male-dominated environments. This is not unique to science. Many industries are still predominantly male, and the experience of being one of very few women in a room has a quiet but real effect on how you see yourself. I noticed early on that male colleagues often projected confidence regardless of their level of experience, while women, myself included, tended to hold back until we felt completely ready. The irony is that the women who hesitate are often the most capable people in the room. I have also experienced imposter syndrome throughout my career – that persistent feeling of not quite belonging or being about to be found out, despite the evidence in front of you. I think many women carry this quietly without naming it. Learning to trust my own abilities and put myself forward even when I do not feel completely ready is something I am still working on, and I suspect I am not alone in that.
Has being a woman influenced your approach to innovation, leadership, or problem-solving in any way?
I think my approach has been shaped more by experience and character than by gender. My first real leadership role came through several years as a Scout leader, which taught me how to motivate people, adapt to different personalities, and lead by example. It gave me a deep appreciation for teamwork and what good leadership actually looks like. Later, my work in R&D reinforced habits I still carry today. Research demands attention to every detail – the ability to observe carefully and foresee problems before they happen. As a person I am a perfectionist, which is a very common trait among researchers. I find it hard to leave something half done or just good enough. I hate to fail. I know it is part of the process and I have learned from every failure I have had, but the feeling never gets easier. If anything it is what keeps me going.
Throughout your career, who or what has inspired you the most?
More than any one individual, I have been inspired by my grandfather. He faced significant physical challenges throughout his life, including being nearly blind, yet nothing would stop him. He approached everything with energy, warmth and curiosity. He was remarkably sharp and deeply loved by everyone around him. When I was studying, he always took a genuine interest in what I was learning. More broadly, I come from a hardworking family where perseverance, resilience, and making the most of opportunities were simply part of everyday life. Those values have stayed with me throughout my education and career and continue to influence how I approach challenges today.
Sleep has become a major topic in health and wellbeing. Why do you think sleep is receiving so much attention today?
I think people are simply more aware of their bodies and their overall wellbeing than they used to be. Sleep is one of those things that has historically been overlooked, treated as something that just happens rather than something that needs attention and care. But modern life is intense. Traffic, work pressure, family responsibilities, the constant demands on our time and attention. Sleep is often the only real window in the day where the body and mind get to recover and reboot. When that window is compromised, everything suffers. At the milder end you slow down, lose focus, feel tired all day. Push it further and you are looking at mental exhaustion, burnout, an inability to function properly. And sleep does not exist in isolation either. It is affected by almost everything around us – the mattress we sleep on, light, sound, stress levels, physical comfort. People are starting to understand that and take it seriously.
From a scientific perspective, why is quality sleep so important for our physical and mental health?
During sleep the body is doing far more than simply resting. At a physiological level, sleep is one of the body’s most important recovery processes. During sleep, the body repairs tissues, supports muscle recovery, strengthens the immune system, and gives the cardiovascular system an opportunity to rest. At the same time, the brain consolidates memories, processes information, and prepares for the demands of the following day. When sleep is consistently disrupted or insufficient, these processes become less effective, which can affect concentration, mood, physical recovery, immunity, and overall health. Over time, poor sleep has been linked to an increased risk of a range of physical and mental health problems, highlighting just how essential quality sleep is to long-term wellbeing.
What are some of the most common misconceptions people have about sleep?
One of the most common misconceptions is that poor sleep is purely a stress or mental health issue. While stress certainly plays a role, people often overlook the importance of their physical sleep environment. Factors such as mattress support, pillow height, temperature, light, and noise can all have a significant impact on sleep quality. Another widespread belief is that a firmer mattress automatically provides better support. In reality, the best sleep surface depends on an individual’s body type, weight, and sleeping position. A mattress that is too firm or too soft can create pressure points, affect spinal alignment, and disrupt sleep without the person fully understanding why.
Are there any particular sleep challenges that you believe women experience differently from men?
From both a scientific and practical perspective, women do seem to experience more sleep challenges than men, and I think this is underappreciated. Hormonal changes throughout a woman’s life – from the menstrual cycle to pregnancy to menopause, directly affect sleep quality in ways that men simply do not experience. These are not minor disruptions. They can significantly alter temperature regulation, comfort levels, and the ability to stay asleep.
Women also tend to report higher sensitivity to pain and physical discomfort during sleep, which makes the physical environment, the mattress, the support, and the pressure distribution, even more critical. I see this at the showroom regularly. Women are often more attuned to what their body needs and more willing to investigate why they are not sleeping well, while men tend to adapt and push through without questioning it.
How did your scientific background influence the way you think about sleep and sleep-related products?
My scientific background fundamentally changed the way I think about sleep surfaces. Where most people see a mattress, I see a material with specific mechanical properties and immediately start thinking about how it interacts with the body, distributes pressure, and supports alignment. Looking at pressure mapping data reinforced how common pressure hotspots are around areas such as the shoulders and lower back, and how these can contribute to discomfort and disrupted sleep. It also highlighted that a mattress is only one part of the equation, with pillows and bed bases playing an important role in maintaining proper spinal alignment. Ultimately, my training taught me to evaluate sleep products based on measurable performance and how effectively they support the body’s recovery during sleep.
What inspired the idea behind Huggah? Can you take us back to the moment when the team realised there might be an opportunity to apply science to improve sleep quality?
Huggah grew out of almost a decade of research into metamaterials, a field focused on materials that behave differently from conventional materials because of their internal structure. As the team explored the potential applications of these concepts, we were struck by how little fundamental innovation had occurred in the mattress industry since the introduction of memory foam. Given the important role sleep plays in health and recovery, we believed there was an opportunity to apply advances in materials science to create something genuinely different. Rather than making incremental improvements to existing products, the goal was to rethink how a sleep surface interacts with the human body, which ultimately became the foundation of Huggah.
Developing an innovative product is never easy. What were some of the biggest challenges the team encountered during the process?
Every stage had its challenges. Building the right team, securing funding, scaling from a research concept to a manufacturable product, getting investors and customers to believe in something they had never heard of. As a startup you maximise every resource to its absolute limit and there were moments where things could easily have gone in a different direction. The irony of building a product designed to improve rest while running on very little of it yourself is not lost on me. But coming through it makes you believe in what you have built even more.
How important was scientific testing and research during the development stage?
Scientific testing and research were central to the entire development process. From the outset, we relied heavily on objective data to understand how the material interacted with the body and how it compared to conventional sleep surfaces. Pressure mapping played a particularly important role, allowing us to visualise load distribution and identify areas where traditional materials were falling short. Scientific testing and research were central to the entire development process.
We also worked with partners who tested our samples independently, and their reactions were consistently one of genuine surprise. The properties of the material were unlike anything they had encountered before. Ultimately, rigorous testing gave us the confidence that we were developing something genuinely different rather than simply another variation of existing mattress technologies.
For readers who may be unfamiliar with it, what exactly is Zetic® Technology? How does Zetic® Technology differ from conventional mattress materials and designs?
Zetic® is the foam technology at the heart of Huggah, and it represents a complete breakthrough in materials science. Developed right here in Malta using metamaterial principles, it is a genuine innovation with no equivalent on the market, protected by patents in the United States and China, among others. It has been sought after by major industry players for decades. While traditional materials tend to spread outward when compressed, Zetic® responds by drawing support towards the body, helping to distribute pressure more evenly and maintain spinal alignment. As weight is applied, more of the material becomes engaged, allowing it to adapt to different body shapes, weights, and sleeping positions, continuously adjusting as the sleeper moves and providing consistent support throughout the night.
What scientific principles make this technology unique?
Unlike memory foam which retains an impression and stays sunk, Zetic® continuously adjusts as the sleeper moves. What also sets it apart is its simplicity. No springs, no multiple layers, no memory foam, no fillers. Just a single layer of scientifically engineered foam that does everything a sleep surface needs to do.
How does it interact with the human body during sleep?
As the body settles into the mattress, the material responds to different pressure points, adapting to the sleeper’s shape, weight, and sleeping position. Rather than allowing pressure to build up in specific areas, the material helps distribute load more evenly across the body while maintaining spinal alignment. As the sleeper moves throughout the night, the material continuously readjusts without retaining a lasting impression, helping to minimise pressure concentrations and provide consistent support. The result is a sleep surface that adapts to the individual rather than requiring the individual to adapt to the mattress.
What benefits have users reported after using products incorporating Zetic® Technology?
The feedback has been fantastic. Customers frequently report waking up with zero back pain, less stiffness, and feeling genuinely more rested. Couples consistently highlight how little they disturb each other during the night, and individuals with chronic pain have described improvements that have genuinely changed their quality of life. One customer who had undergone back surgery called it a game changer. Another told us their partner, who had been unable to sleep more than a couple of hours at a time, was now sleeping close to eight hours a night. For that family it was life changing. We have also had clients with fibromyalgia reporting better recovery and rest, which for a condition that affects sleep so significantly is particularly meaningful.
From a performance perspective, comfort, pressure relief, support, alignment, and thermal comfort all score above nine out of ten at the two week mark across a wide range of body types and sleeping positions. But honestly, the numbers tell only part of the story. What stands out most is how many people describe the experience as feeling completely different from the moment they first lie down.
Were there any surprising discoveries during the development or testing phase?
We knew from the outset that the mechanical properties of Zetic® were superior to conventional foams. That was the foundation of everything we had built. What genuinely surprised us was how well the thermal and motion isolation properties performed. Because of the structure of the material, air continues to move through it even under load, reducing heat build-up without requiring any additional cooling technologies. And the degree to which movement on one side of the mattress is absorbed without transferring to the other significantly exceeded our expectations. Neither of these was engineered as a separate feature. Both emerged naturally from the underlying material design, which told us that what we had created was more capable than even we had anticipated.
Durability was something we expected, but the extent of it still surprised us. The material maintained its structure and performance far beyond what standard longevity testing would typically cover, significantly outperforming conventional foams. That gave us real confidence in standing behind a ten-year warranty.
How do you see sleep technology evolving in the coming years?
Sleep technology has remained relatively unchanged for decades, but I believe we are entering a period of much greater innovation. Advances in materials science will continue to improve how sleep surfaces adapt to individual needs, and we intend to be at the forefront of driving that change. Developments in sensors, sleep tracking, and data analytics will provide people with a better understanding of their sleep habits and recovery. At the same time, sustainability is becoming an increasingly important consideration, creating demand for products that are both high performing and easier to recycle at the end of their life. Huggah is already ahead on this, with a single layer core that requires no additional treatment and can be recycled and reused. Ultimately I think the future of sleep technology lies in combining scientific innovation, personalisation, and sustainability to create better sleep environments and improve long-term wellbeing.
Are there any new projects or innovations currently in development that you can share with us?
Our focus is on the mattress and on continuing to build on what we have created. That is our specialisation and where our expertise lies. We are beginning to think about how the same principles could extend to other parts of the sleep environment such as toppers and pillows, but we want to do that properly and at the right time.
What would you like people to understand about the science behind better sleep?
Sleep is far more complex than most people realise. It is not simply a matter of putting your head on a pillow and switching off. One of the biggest misconceptions about sleep is that it is simply a matter of how many hours you spend in bed. In reality, sleep quality is influenced by a wide range of factors, including temperature, pressure distribution, movement, light, noise, and overall comfort. Even small disruptions can interfere with the body’s natural sleep cycles and reduce the restorative benefits of sleep without a person fully realising it. Understanding this helps shift the focus from simply getting more sleep to creating an environment that supports deeper, more consistent, and more restorative rest.
If readers could take away one message from this interview, what would you like it to be?
Sleep is not a luxury, it is a necessity, and yet it is one of the most underinvested areas of most people’s lives. People spend significant money on cars, clothes, gym memberships, and food, all of which matter, but then give very little thought to the surface they spend a third of their life on. The science is clear: sleep affects everything – your energy, your mood, your physical recovery, your cognitive performance. Getting it right starts with understanding that your sleep environment is worth taking seriously.
Finally, what does a good night’s sleep mean to you personally?
For me a good night’s sleep means waking up ready. Ready to think clearly, move well, and face whatever the day brings. After everything I have learned about the science of sleep, I take it seriously. But honestly, like most people, I still do not always get it right. That is probably what keeps me motivated to keep working on it.
