Stop guessing how to make 2026 the year you feel like yourself again. 

That was the promise behind our recent webinar, The Science of Feeling Better in 2026, where CeraThrive CEO Sarah Turner sat down with someone we're incredibly excited to introduce: Dr. Arpit Bansal, a renowned cancer surgeon, gut specialist, and longevity expert who has joined CeraThrive as our Chief Medical Officer. 

What followed was a fascinating exploration of how a surgeon and a neuroscientist are approaching gut-brain health, and why the way we think about wellness might need a complete reframe. 

Meet Dr. Arpit Bansal

Dr. Bansal brings a rare combination of clinical expertise and holistic thinking to CeraThrive. As a practising cancer surgeon in India, he sees patients every day whose physical symptoms are deeply intertwined with their mental state. Young patients arriving with gut issues and digestive complaints who, upon deeper investigation, reveal underlying anxiety, disrupted sleep, and circadian rhythm dysfunction. 

His observation? These issues are connected 99% of the time. 

This clinical reality led Dr. Bansal down a path exploring longevity, resilience, and the profound relationship between water, calm, and human wellbeing, eventually bringing him to a concept that became central to our conversation: the "blue mind" and the "red mind." 

Red Mind, Blue Mind: A New Way to Understand Your Nervous System 

Dr. Bansal introduced a beautifully simple framework for understanding the autonomic nervous system: 

1. Red mind corresponds to the sympathetic nervous system - the fight-or-flight response. It's the state you need when running, performing surgery, or responding to immediate threats. Anything that elevates your heart rate. 
2. Blue mind corresponds to the parasympathetic nervous system - rest and digest. It's the state of wellbeing, calm, and happiness. Anything that brings your heart rate down: breathing, meditation, being near water. 

Here's where it gets interesting: humans reflexively shift into a "blue mind" state when near, around, or even simply hearing water. Dr. Bansal attributes this to our origins, we spent the first nine months of life in the watery environment of the womb. We are, quite literally, water babies. 

The problem is, modern life keeps us stuck in chronic red mind. The constant stress, screens, and demands create a state of persistent sympathetic activation that drives inflammation, damages the gut, and undermines our capacity for true healing. 

As Dr. Bansal explained, true longevity happens in a parasympathetic-dominant state. Less red mind. More blue mind. 

The Gut-Brain Connection: One Regulatory Circuit

The conversation took a deep dive into something we're passionate about at CeraThrive: the gut-brain axis. Dr. Bansal offered a perspective that reframes how we think about this connection entirely. 

Biology, he explained, does not treat the gut and brain as separate organs. They function as a single regulatory circuit, connected through: 

• Neural pathways (the vagus nerve) 
• Immune pathways (cytokines and immunomodulatory signals) 
• Endocrine pathways (linked through circadian rhythm) 
• Microbial metabolites (produced by the gut microbiome) 

This explains why gut dysfunction manifests as brain fog, why anxiety disrupts digestion, and why addressing one without the other often falls short. 

Photobiomodulation as a Biological Signal 

So where does red light therapy fit into this picture? 

Dr. Bansal was careful to frame photobiomodulation not as a treatment, but as a biological input signal. It's a subtle but important distinction. PBM works through three primary mechanisms: 

• Mitochondrial signaling: Red and near-infrared light interact with cellular pathways, affecting mitochondrial energy production and redox balance. 
• Nitric oxide and blood flow: PBM stimulates nitric oxide pathways, improving microcirculation and reducing inflammatory noise. 
• Inflammation modulation: At a cellular level, light therapy helps calm the inflammatory response, creating conditions for healing. 

What makes CeraThrive's approach unique, according to Dr. Bansal, is the simultaneous targeting of both ends of the gut-brain axis. The vagus nerve is bidirectional - it communicates both up to the brain and down to the gut. Stimulating both ends at once, through the CERA headband and body panel, creates a synergistic effect that single-site approaches cannot achieve. 

This out-of-the-box thinking, aligned with nature and grounded in molecular biology, is what drew him to join CeraThrive as CMO. 

Conditions with Strong Gut-Brain Connection

When asked which conditions researchers are most interested in exploring with targeted gut–brain photobiomodulation, Dr. Bansal pointed to irritable bowel syndrome (IBS).

“IBS is widely recognized as having a strong gut–brain component,” he explained. “It involves both neural signaling and inflammatory pathways, which makes it a compelling area for continued research into approaches that target both the gut and the brain.”

He was also careful to emphasise that PBM is not a replacement for medical treatment, but a valuable adjunct. The best results come when light therapy is paired with a 360-degree approach: attention to sleep timing, hydration, movement, and metabolic stability. 

Brain Waves and Frequency: Alpha, Gamma, and Beyond 

The webinar also touched on something that often sparks curiosity about the CERA System: brain wave entrainment. 

Dr. Bansal explained the different brain states by frequency:

• Beta waves (12–20 Hz): Active, alert, focused 
• Alpha waves (8 Hz): The "magic state" between sleep and wakefulness, closely aligned with the Earth's Schumann Resonance (7.83 Hz) 
• Gamma waves (40–100 Hz): Associated with extreme concentration, insight, lucid dreaming, and high-level creativity 

The CERA System uses pulsing light at frequencies like 7.8, 10, 40, and 100 Hz to help the brain naturally entrain to these states. It's a gentle nudge toward the mental states we're often trying to cultivate through meditation, breathwork, or deep focus. 

Questions from Our Community 

We were thrilled by the engagement during the webinar. Attendees asked thoughtful, curious questions that reflect the depth of interest in this space: 

Can photobiomodulation help with forgetfulness? While cautioning against the word "reverse," Dr. Bansal noted emerging research exploring PBM in neurodegenerative contexts. It may support sleep quality, improve brain energy signalling, and help activate the glymphatic pathway - all foundational benefits that could support cognitive function. 

Can you impact oral flora with gut PBM? The oral microbiome is an extension of the gut microbiome. Building resilience in the gut creates a foundation that helps the entire system handle challenges more effectively. 

How do I know if I'm using it too much or too little? Your body provides feedback. Benefits show up as better sleep, a calmer stress response, and increased resilience. Interestingly, those who are most depleted often need less light, exhausted mitochondria respond to smaller doses, while healthy cells can tolerate more. 

The Key Takeaway 

If there's one thing Dr. Bansal wanted viewers to remember, it's this: photobiomodulation supports regulation and recovery, but it is not a replacement for diagnosis or cure. 

True health is a 360-degree approach, not a narrow, disease-centric one. Sleep, hydration, movement, metabolic stability, and nervous system regulation all work together. PBM is one powerful tool in that toolkit, helping to shift the body from chronic red mind toward the calm, regenerative blue mind state where real healing happens. 

What's Next 

We're incredibly excited to have Dr. Bansal guiding the medical and scientific direction of CeraThrive. His clinical experience, understanding of the gut-brain connection, and vision for integrative health align perfectly with our mission. 

If you missed the webinar, stay tuned - we'll be sharing more conversations, insights, and science in the months ahead. And if you're ready to explore how the CERA System can support your journey toward feeling like yourself again, we'd love to hear from you. 

Here's to making 2026 the year you stop guessing - and start feeling better.
