Progress without the competitive, task-driven overload, and it even nourishes the soul.
Safeguarding our healthspans has become a daily effort. If we’re not resistance training, we’re cold plunging before getting under the red light therapy, all fuelled on a calorie deficit. Has there ever been a moment in human history when we’ve been more invested in our future selves?
The concept of biohacking has played a huge part in all this self-optimisation with sleep, cognitive performance and fitness being held under a constant microscope. But in the midst of all the tracking and biometrics, there have been murmurings of biohacking not being the all-encompassing solution we’ve been searching for. With a background in neuroscience, and psychiatry, world-renowned longevity doctor, Dr Tamsin Lewis points out what we might all have been missing.
Q. When and why do you think the world went mad for biohacking?
DR TAM: Biohacking took off when people realised that conventional medicine wasn’t helping them feel better - just managing disease. As wearable tech, blood tests and podcasts exploded, a wave of self-experimentation gave people a sense of agency. But ultimately, it’s a modern iteration of something very human: the desire to live with more vitality and longevity.
Q. What are your concerns with biohacking and what negative side effects are you seeing?
DR TAM: Stacking your hacks is stressful and it’s been highlighted that some of the world’s top Bio-Hackers have super high cortisol levels. I see this all the time, there is morning routine and then there is morning obsession.
What happens if you get 1min of morning light exposure as opposed to the optimal 10 min? You beat yourself up for the rest of the morning. Biohacking can easily tip into overstimulation and obsession. I see people overwhelmed by stacks of supplements, cold plunges, biofeedback loops and endless tracking. Often, they’re missing the basics - like breathing, sleep, light exposure and meaningful emotional connection.
Q. Who might not be suited to biohacking?
DR TAM: Those with compulsive, perfectionist tendencies often fall into the trap of chasing numbers and protocols, losing touch with how they actually feel. More data doesn’t always mean more wisdom. Health isn’t something we force - it’s something we create the conditions for and without nervous system regulation and co-regulation, all that input becomes another stressor. I’d encourage these individuals to start with softer tools - nervous system retraining, nature time, bodywork, and nourishment - and let health unfold from there.
Q. What does bioharmonising mean to you?
DR TAM: Bioharmonising is the feminine to the masculine of biohacking. It’s about working with your body, not against it and centres around rhythm - circadian, seasonal, hormonal, emotional. It favours time in nature and positive lifestyle habits like natural light and exercise outside rather than the gym, primal movement rather than machines, time with family and friends. It encourages joy, spiritual practice and connection with self. Bio-harmonising is the essence of what I see as regenerative medicine - supporting the body’s innate intelligence to repair and thrive.
Q. How does bioharmonising differ from biohacking - and where might it be superior?
DR TAM: While biohacking may provide short-term benefits by targeting specific goals or functions, such as improving cognitive performance or physical fitness, it is often reductionist and can overlook the broader context of overall health and wellbeing.
Bioharmonising is considers the whole person - nervous system state, environment, history, community. Where hacking can be extractive, bioharmonising is restorative. For many - especially those burnt out, inflamed or hormonally depleted - it’s not only safer but ultimately more effective.
Q. How does the natural world support bioharmonising?
DR TAM: Reconnecting with the natural world is one of the most powerful - and overlooked - forms of medicine we have. Nature co-regulates us. Light, temperature, sound, even the microbiome in soil - these are all cues our biology depends on. My personal favourite harmoniser? A moderately cold sea swim. It clears the mind, calms inflammation, and resets the nervous system.
Q. What’s the most important data to track for long-term health?
DR TAM: While tools like HRV, glucose variability, and epigenetic age are useful, subjective feedback is often more telling. How rested do you feel? Are you emotionally responsive or reactive? Can you connect with others with ease? These are biomarkers, too - just less easily monetised. A truly long life must also feel good from the inside.
Q. What tech or tools do you personally use to support bioharmonising?
DR TAM: I use an Oura Ring for sleep and recovery, Levels intermittently for metabolic tracking, and Nurosym or Apollo Neuro for vagal tone. I’m a long-time advocate of photobiomodulation (PBM) - red and near-infrared light to support mitochondrial and brain health. And I always come back to breath - tools like State help me shift gears in minutes.
Q. Should we always be striving to improve ourselves?
DR TAM: Not always. There’s wisdom in knowing when to grow and when to soften. Health happens in cycles - tension and release, effort and repair. Constant striving can exhaust the very systems we’re trying to support. True resilience lies in adaptability, not intensity. Sometimes the most healing thing we can do is rest, restore, and let go.
Q. How do you see the LYMA Laser fitting within a bioharmonising framework?
DR TAM: The LYMA Laser is an elegant, non-invasive example of regenerative medicine - it works through PBM to reduce inflammation, support collagen production, and promote tissue repair without overstimulating the system. I see it as a supportive tool in a streamlined, effective longevity and regeneration protocol.
Q. What are your top daily bioharmonising techniques we can use before breakfast?
-
Natural light exposure - ideally outside within 30 minutes of waking to anchor circadian rhythm and lift mood.
-
Breath-led co-regulation - just 3–5 minutes of slow, nasal breathing or humming can activate vagal tone and calm the system.
-
Sugar-free or natural electrolyte drink - to replenish key minerals lost overnight and support morning energy, hydration and adrenal tone.
-
The LYMA Supplement - intelligently formulated to address modern micronutrient gaps, mitochondrial function and stress resilience.
