Now that we have unpacked the different types of qualia and how they can be deeply personal and often subconscious, let us bring it home to women in midlife experiencing the brain makeover of Perimenopause.

Common Experiences of Women in Midlife:

Hormonal fluctuations is a hallmark of perimenopause and menopause. Fluctuating estrogen and progesterone levels directly impact important neurotransmitter systems like serotonin, dopamine, and GABA, used for regulating mood, sleep, cognition, and stress response. This comes with a whole gamut of presentations, some of which are:

• Mood Swings: Increased irritability, anxiety, and heightened emotional sensitivity.

• Sleep Disturbances: Insomnia and disrupted sleep patterns, leading to feelings of fatigue and reduced cognitive function during the day.

• Cognitive Changes: Brain fog, memory lapses, and difficulty concentrating, impacting daily clarity.

• Increased Stress Vulnerability: A diminished capacity to cope with everyday stressors, making small irritations feel monumental.

• Physical Symptoms: Hot flushes (or flashes), joint pain, and headaches, all contributing to discomfort and impacting overall well-being.

  On top of that, midlife tends to coincide with transitions that amplify sensory sensitivity, leaving many women wondering why their home feels overwhelming in midlife. Think children leaving home, caring for aging parents, career re-evaluations, or changes in relationships, to name a few.

  The confluence of these hormonal shifts and life changes often trigger a fundamental re-evaluation of our sense of identity, our current and future obligations and life priorities.

This season of brain renovation leads to a powerful shift in subjective experience. What previously felt tolerable or even pleasant in your environment may now feel irritating, overwhelming, or draining.

For example, while i have always preferred quiet environments over noisy ones, ever since i entered perimenopause, the loud, bustling ambience of city life always left me feeling drained and irritable - never mind unable to fall asleep because my brain is busy talking incessantly at me. So commuting into the city for work feels like a task i must prepare for.

The desire for peace and an environment that supports the cultivation of that peace increased exponentially, and i prioritised that when looking looking for a house. It had to be suburban and i had to be surrounded by nature, with minimal vehicular and human traffic.

For us women, the subjective experience of our home environment—the qualia—can either exacerbate our challenges or provide sanctuary. If our homes are consistently filled with stress, discomfort, or overstimulation (e.g. harsh lighting, loud noises, clutter), it will significantly worsen our mood, sleep and overall well-being.

A home designed to intentionally elicit qualia of calm, security, comfort, and support is a powerful tool for self-regulation and resilience during this transformative period of our lives.

This is where it gets a bit more sciencey for those who want the empirical data. If you are not into it, just skip this section.

While neuroscientists have not found one specific part of the brain that processes 'qualia' (the subjective experience of a thing), there is a lot of evidence from the study of the brain and the psychology of the environment that helps us understand the brain and behavioural changes that lead to specific 'qualia' in our homes.

Thanks to neuroscience, we understand the intricate sensory processing pathways in the brain.

For instance, the visual pathway (occipital lobe), auditory (temporal lobe), and somatosensory (parietal lobe) areas process raw data.

Their interaction, especially with regions involved in emotion and memory like the amygdala and hippocampus, gives rise to the subjective feeling of an experience.

A jarring sound in the home, for instance, processed rapidly by the amygdala for emotional salience, can trigger feelings of irritation, contributing to negative auditory qualia.

We also know how specific neurotransmitter systems are impacted by environmental factors. For example, light exposure directly affects melatonin and serotonin levels, influencing sleep and mood, and how certain colours can activate reward pathways (dopamine) or stress responses (cortisol).

The prefrontal cortex, the area of the brain that is critical for executive function and decision-making, is significantly impacted by environmental stressors or supportive elements, influencing one's cognitive qualia (e.g., feeling clear-headed versus foggy).

Different brainwave states (alpha, beta) are associated with different qualia, with calm environments promoting relaxing alpha waves. This highlights how design choices influence brain activity.

Most importantly, we understand neuroplasticity, which means our brains are constantly adapting.

Repeated exposure to certain stimuli in the home can reshape neural pathways, reinforcing specific qualia and emotional responses over time.

So, a home that consistently elicits feelings of safety and comfort can strengthen neural circuits associated with well-being.

This field studies how people and their surroundings interact. It shows us how the experiences we have in our environments can affect how we feel. There are are what i would refer to as four axes that relate to our experiences in our home environments:

• Attention Restoration Theory (ART): This theory demonstrates that natural environments (or elements mimicking them) can restore directed attention, which is often fatigued by demanding cognitive tasks. Read more here.

  The soft fascination of nature (e.g., a view of trees, the sound of water) allows for effortless engagement, reducing mental fatigue and promoting positive cognitive qualia. This translates to home design when we maximise the use of natural light, introduce plants, and create natural views.

• Stress Reduction Theory (SRT): It has been shown that exposure to natural environments can reduce physiological stress (e.g., lower heart rate, blood pressure, muscle tension).

  Read Ulrich, R.S. work on Stress reduction theory here.

  Even simulated nature has the same effect. A home that feels natural through its materials, colours, and organisation will elicit qualia of calmness and safety.

• Place Attachment and Identity: Our homes are inextricably linked to our sense of self, place and belonging. Positive experiences and memories associated with a particular space, results in strong place attachment, which creates feelings of security, comfort, and identity. Read more here.

  A home that reflects your personality and values fosters these feelings.

• Personal Control and Perceived Control: Another descriptive for this is 'Human Centered Interior Design'. Our ability to modify our environment (e.g. adjusting lighting, temperature, privacy) increases our sense of agency and control.

  This has been shown to be a powerful predictor of wellbeing. This approach to designing our residential spaces, puts the user (you) at the center of the design process. your home environment is then designed with you as the active player in the space, where everything revolves around how you function, to give you the best support,

  Lack of control over how you need your space to support you, inevitably leads to feelings of helplessness and negative emotions. This has been my argument against communal building projects. While they are amazing for fostering connection, i wonder if we are factoring in the need for human beings to have autonomy over their environments?

  But this is a topic for another journal entry.

Now, this is where it all comes together!!

Now that we can see evidence backed by neuroscience and psychology, showing that Qualia is not woo, we don't need to go looking for where qualia lives in the brain to validate their importance.

We validate them through:

• Observable Behavioural and Physiological Responses: We can measure reduced stress hormones, improved sleep patterns, enhanced cognitive performance, and self-reported well-being in response to specific environmental designs. These are the external manifestations of positive qualia.

• Subjective Reporting and Phenomenology: We listen to people's descriptions of their experiences.

  "I feel calmer in this room,"

  "This colour makes me feel anxious,"

  "I can finally think clearly here."

  These are direct reports of qualia, and when aggregated, patterns emerge that inform effective design principles.

• Biometric Data: Heart rate variability, skin conductance, and even fMRI studies (looking at activation in emotion/reward centers) can provide objective correlates to subjective experiences, reinforcing the profound impact of design choices on qualia.

• Embodied Cognition: Our minds are not separate from our bodies and environments. Our bodily sensations and movements within a space directly contribute to our cognitive and emotional states, and thus to our qualia.

So how do we begin designing our homes to support cognitive, physical and emotional design? We start by keeping in front of mind that design is not solely for function or aesthetics. It is also crucially for the feeling the space evokes.

A few of these cardinal points to consider are:

• Use Sensory-Rich but Balanced Environments (tailored to the individual):

1. Visual: Prioritise soft, non-glaring layered lighting, maximise natural light access, incorporate views of nature, use calming colour palettes, and declutter to reduce visual noise.

2. Auditory: Implement sound-dampening materials, consider white noise generators if helpful, isolate noisy appliances, and create quiet zones for retreat.

3. Tactile: Introduce diverse textures (soft fabrics, smooth wood, warm rugs) and comfortable, supportive furniture.

4. Olfactory: Ensure good ventilation, use natural scents (essential oils, fresh flowers), and avoid harsh chemical cleaners.

• Promote Restoration and Calm: Design dedicated 'restorative zones' for quiet contemplation, reading, or meditation. Incorporate elements of nature (biophilic interior design) like indoor plants, natural materials, and views of greenery.

• Support Circadian Rhythms: Maximise natural light exposure during the day and minimise blue light at night to support melatonin production and healthy sleep-wake cycles, which are crucial for hormonal regulation.

• Enhance Perceived Control: Allow for adjustable lighting, temperature, and privacy to optimise stress reduction through design. Provide flexible furniture arrangements that adapt to changing needs.

• Foster Safety and Security: Ensure clear pathways, good visibility, and offer comfortable, enclosed spaces for retreat when needed.

• Encourage Movement and Physical Comfort: Include ergonomic furniture, designate spaces for gentle exercise (e.g., a yoga mat area), and ensure comfortable seating throughout the home.

• Minimise Environmental Stressors: Actively reduce clutter, address sources of noise pollution, and ensure excellent indoor air quality.

For women in a midlife stage, this means making a conscious effort to create spaces that reduce common symptoms of the menopause. For example, cool, breathable bedding and good air circulation can help with hot flushes, making you feel more comfortable. The list is, of course, not exhaustive.

Being a detective in your own life – actively understanding how your environments influence you, and why – is crucial for everyone, but particularly empowering for women navigating midlife changes.

Here's why:

1. We often interact with the environment without realising it. We might feel tired or stressed, but we might not realise that it's because of the bright overhead lights, the messy counter, or the noise of traffic outside.

Being a detective means being aware of these influences and understanding them better. It is about being aware of your feelings. For example, ask yourself "How does this light make me feel?" or "What's the feeling of being in this room right now?"

2. You are taking charge of your own wellbeing. When you understand how your environment affects your state of mind, you go from being someone who just goes along with what's happening around you to someone who can make things happen. You realise that you can change your environment to make yourself feel better. This feeling of being in control is really powerful, especially when many women feel like they're losing control because of changes in their hormones.

3. You can create your own personalised solutions, or get help from a designer. There is not one "ideal" environment. What makes one person feel calm might make another person feel bored. The same is true of what makes one person feel excited, and another person feel overwhelmed.

By taking a look at your own needs, you can find out what is important to you in your relationship with your environment. This means you can get advice that is exactly right for you, for all aspects of your health – mental, physical and emotional.

4. You become your own proactive health manager. Instead of waiting for symptoms to manifest (e.g., anxiety, insomnia, irritability), you can proactively design a calming home during menopause to prevent or mitigate symptoms. This is a cornerstone of preventive health and resilience building, giving you a powerful tool in your midlife toolkit.

5. Whether it's choosing a new home, renovating a room, or simply rearranging furniture, understanding your environmental sensitivities empowers you and allows for informed decisions that align with your deepest needs and support your health goals. It shifts decision-making from arbitrary preference to strategic self-care.

6.For women experiencing hormonal changes, their own experiences can sometimes be dismissed or attributed solely to "hormones". If you understand the environmental influences, you can be sure of your feelings. "It's not just me; this noisy environment is making my anxiety worse."

This agency is really important for your mental health and your ability to create an environment where you can be happy with yourself.

I bet you are starting to wonder 'how do i even begin to do this? It's simple.

Being a detective involves:

• Mindful Observation: Paying close attention to how you feel in different spaces and at different times of day.

• Self-Experimentation: Making small, intentional changes to your environment and observing the immediate and long-term impact on your mood, energy, and cognitive function.

• Journaling/Tracking: Noting patterns between specific environmental stimuli and your internal states (e.g., "After 30 mins in the bright kitchen, I feel irritable").

• Curiosity and Openness: Being willing to explore and question your assumptions about your surroundings, and to try new things even if they seem unconventional.

Your home is this dynamic extension of your nervous system, and it is constantly interacting with your senses and influencing your well-being at a deeply subconscious level.

Understanding this phenomenon of qualia with the powerful insights from neuropsychology and environmental psychology, you gain an unparalleled tool to design a living environment that actively supports you through midlife and beyond.

This is the time to be the detective in your own life. Listen to the subtle signals your qualia are sending. Observe how different elements in your home make you feel, think, and even remember.

You have the power to curate a space that is not just aesthetically pleasing, but one that is profoundly healing and uniquely aligned with the incredible, evolving woman that you are.

1. What exactly is qualia, and how does it relate to my home?

Qualia refers to the raw, subjective experiences that arise from our senses—like the feeling of sunlight on your face or the scent of morning coffee. In the context of your home, qualia describes how your space feels to you, beyond its physical structure. It's the difference between a room that feels peaceful and one that feels agitating, even if they look similar.

2. Why does my home suddenly feel overwhelming in midlife?

During midlife, hormonal shifts (especially in perimenopause and menopause) can heighten sensory sensitivity and emotional reactivity. This means environments that once felt fine may now trigger anxiety, brain fog, or fatigue. You're not imagining it—your brain and body are experiencing space differently, and design adjustments can help.

3. Can home design really help with mood swings, brain fog, and stress?

Yes. Research in neurodesign and environmental psychology shows that lighting, color, texture, scent, and spatial layout directly influence brain function and emotional states. Adjustments like warmer lighting, clutter reduction, and calming colors can support better sleep, mood regulation, and mental clarity—especially during hormonal transitions.

4. What are some signs my environment is negatively affecting me?

Common signs include:

• Feeling fatigued or irritable in certain rooms

• Trouble concentrating in your workspace

• Difficulty sleeping due to lighting or noise

• Emotional discomfort you can’t quite explain

These may reflect negative qualia, which can often be alleviated through design changes.

5. What is a brain-friendly home, and how do I create one?

A brain-friendly home supports your cognitive and emotional well-being through intentional sensory design. This includes:

• Natural light during the day and warm lighting at night

• Calming, non-overstimulating color schemes

• Quiet zones for rest and focus

• Scent and soundscapes that promote relaxation

• Layouts that support easy movement and comfort

This approach is especially effective for women experiencing midlife neurohormonal changes.

6. I’m sensitive to noise and clutter—what can I do?

If you're experiencing sensory overload, consider:

• Using noise-dampening materials or white noise devices

• Decluttering visually chaotic spaces

• Creating “retreat zones” with minimal stimulation

• Rearranging furniture to allow smoother movement

  
  These adjustments reduce stress-inducing qualia and increase your sense of control.

7. Do I need an interior designer to make these changes?

Not necessarily. But working with someone who understands qualia and neurodesign can be transformative. They can help you translate your felt experiences into practical design choices. Most importantly, they validate how your space makes you feel—and design with that in mind.
