In an era where chronic disease rates are skyrocketing and traditional healthcare often focuses on treating symptoms and “diseases” with pharmaceuticals, a revolutionary approach to health optimisation is gaining momentum: biohacking. Far from being a trendy wellness fad, biohacking represents a fundamental shift towards taking control of your health using science, data, and evidence-based strategies.
Biohacking is the practice of using natural methods, lifestyle modifications, and cutting-edge technologies to enhance how your body functions. It's about working with your body's innate systems to optimise performance, longevity, and overall wellbeing. From simple morning sunlight exposure to advanced genetic testing, biohacking offers tools for everyone, regardless of where you are on your health journey.
Australia is uniquely positioned to lead this healthcare revolution. With our outdoor lifestyle, access to natural environments, and growing awareness of preventative health, we have the perfect foundation to embrace biohacking principles. This guide will take you through evidence-based strategies that can transform your health, backed by peer-reviewed research and practical implementation advice.

At its core, biohacking is rooted in understanding and optimising your body's natural systems. Unlike quick fixes or one-size-fits-all approaches, biohacking recognises that each person's biology and genetics are unique and require personalised strategies for optimal function.
The fundamental principle behind biohacking is hormesis – the concept that mild stressors can trigger beneficial adaptations in the body. When you expose yourself to controlled stressors like cold therapy, heat exposure, or intermittent fasting, your body responds by becoming stronger and more resilient. This adaptive response is what makes biohacking so powerful.
Modern biohacking combines ancient wisdom with cutting-edge science. Many of the most effective biohacking strategies – such as morning sunlight exposure, grounding, and heat therapy – have been used by traditional cultures for thousands of years. Today's research is simply validating what our ancestors intuitively knew about optimising human health.
The key difference between evidence-based biohacking and wellness trends lies in measurable outcomes. True biohacking focuses on biomarkers, data tracking, and peer-reviewed research rather than anecdotal claims. This scientific approach ensures that the strategies you implement actually work and provide tangible benefits to your health.
Before diving into advanced technologies, mastering the fundamentals is crucial. These foundation-level strategies form the bedrock of any successful biohacking protocol and often provide the most significant health improvements.
Morning Sunlight Exposure and Circadian Rhythm Optimisation Your circadian rhythm governs virtually every aspect of your physiology, from hormone production to cellular repair. Research published in the Journal of Clinical Medicine shows that morning light exposure within the first hour of waking helps synchronise your internal clock, improving sleep quality, mood, and metabolic function (9). Aim for 10-20 minutes of direct sunlight exposure to your eyes (without sunglasses) each morning as soon as you wake up. Witnessing the sunlight can have more profound benefits, but if you’re not a morning sunrise type of person, just get into the sunlight as soon as you wake up- and don’t take your phone with you!
Quality Sleep Strategies Sleep is perhaps the most powerful biohack available, yet it's often overlooked. During sleep, your brain clears metabolic waste, consolidates memories, and releases growth hormone. Studies consistently show that poor sleep quality is linked to increased risk of cardiovascular disease, diabetes, and cognitive decline (10).
Optimise your sleep by maintaining consistent sleep and wake times, keeping your bedroom cool (18-20°C), and avoiding blue light exposure 2-3 hours before bedtime. Consider using blue light blocking glasses after dark, as research shows they can significantly improve sleep quality by reducing melatonin suppression when worn for 2 hours before bedtime (11). Additionally, minimise electromagnetic fields (EMFs) in your bedroom by keeping devices away from your bed, as studies indicate EMF exposure can disrupt sleep quality and melatonin production (12).
Being Outside in Nature Spending time in natural environments offers profound health benefits that go far beyond simple relaxation. Forest bathing, or shinrin-yoku as it's known in Japan, involves immersing yourself mindfully in nature. Research published in Environmental Health and Preventive Medicine shows that forest environments increase natural killer (NK) cell activity, boost immune function, and reduce stress hormones like cortisol (13). The phytoncides (natural compounds) released by trees have been shown to enhance immune system function and may even improve gut microbiome diversity (14).
Seaside Benefits The ocean offers unique therapeutic benefits through negative ion exposure and natural meditation opportunities. Coastal environments are rich in negative ions, which research suggests can improve mood, reduce stress, and enhance overall wellbeing (15). Interestingly, the rhythm of ocean waves naturally synchronises with optimal breathing patterns for relaxation – waves typically occur at 6-8 cycles per minute, which closely matches the ideal breathing rate of 4-7 breaths per minute for deep meditative states (16). This natural synchronisation explains why many people find the sound of waves so deeply calming and restorative.
Dietary Hacks Making any significant change to your diet is essentially a biohack – you're using evidence-based strategies to optimise how your body processes nutrients and maintains stable energy levels. The beauty of dietary biohacking lies in its simplicity; small changes in what and how you eat can produce profound metabolic improvements.
Whole Food and Ancestral Eating Principles Ancestral eating principles focus on consuming whole, unprocessed foods that humans have eaten for thousands of years. This includes grass-fed meats, wild-caught fish, organic vegetables, fruits, nuts, and seeds whilst avoiding processed foods, refined sugars, and industrial seed oils. Research published in the American Journal of Clinical Nutrition demonstrates that whole food diets significantly reduce inflammation markers and improve metabolic health (17).
Intermittent Fasting Intermittent fasting involves cycling between periods of eating and fasting, allowing your body to shift from glucose to fat burning for energy. This metabolic flexibility can improve insulin sensitivity, support cellular autophagy (the body's natural detox process), and may enhance longevity. Common approaches include the 16:8 method (16 hours fasting, 8 hours eating) or the 5:2 approach (normal eating 5 days, restricted calories 2 days).
Food Sequencing: The Order Matters One of the most powerful yet simple dietary biohacks is changing the order in which you eat your food. Research published in the NIH shows that eating vegetables and fibre before carbohydrates can significantly improve blood sugar control (28). When you eat your salad or vegetables first, followed by protein, and finish with carbohydrates like rice, bread, or pasta, you can reduce post-meal glucose spikes and improve insulin sensitivity.
The science is compelling: studies found that individuals with Type 2 diabetes who ate carbohydrates last experienced significantly lower post-meal blood sugar levels compared to when they ate carbs first (29). This simple change works because fibre creates a gel-like substance in your digestive system, slowing the release of glucose into your bloodstream and preventing rapid blood sugar spikes.
In practical terms, start your meal with a salad or steamed vegetables, then eat your protein (meat, fish, eggs), and finish with any starchy carbohydrates. This sequence can reduce glucose spikes by up to 73% and insulin spikes by up to 48% – that's a massive metabolic improvement from simply changing the order of your meal!
Movement and Exercise Optimisation
Human bodies are designed for movement, yet modern life often involves prolonged sitting and minimal physical activity. The good news? Recent groundbreaking research shows you don't need to be a fitness fanatic to gain significant health benefits.
A landmark 2023 study published in JAMA Network Open followed over 3,000 US adults and found that people who walked just 8,000+ steps on only 1-2 days per week showed a 14.9% lower all-cause mortality risk compared to inactive individuals. Even more impressive, UCLA Health research published in February 2025 demonstrated that people taking 8,000 steps daily were 50% less likely to die during a 9-year follow-up compared to those getting only 4,000 steps.
This research revolutionises how we think about exercise - it's not about perfection or daily intensity, but about consistency and achievable goals. The benefits plateau around 6,000-8,000 steps for people over 60, and 8,000-10,000 steps for those under 60, meaning you don't need to chase unrealistic step counts to optimise your health.
Effective exercise biohacking incorporates varied movement patterns that mimic natural human activities: strength training, cardiovascular exercise, mobility work, and simply walking more throughout the day. For added benefits, try movement that incorporates social connection, as research shows that social exercise provides additional mental health and motivation benefits. My personal favourite is pickleball – it combines cardiovascular exercise, hand-eye coordination, social interaction, and is accessible to all fitness levels.
The key is making movement enjoyable and sustainable. Whether it's dancing, hiking, swimming, or playing sports, find activities you genuinely enjoy. Your body will thank you for the consistency, not the intensity.
Stress Management and Meditation Chronic stress is one of the biggest threats to optimal health, triggering inflammation, disrupting sleep, and impairing cognitive function. Meditation and mindfulness practices have been shown to reduce cortisol levels, improve immune function, and enhance overall wellbeing (19). Even 10-15 minutes of daily meditation can provide significant benefits.
Music and Sound Therapy This section is deeply personal for me- my mum suffered 10 cerebral infarcts (strokes) after her Covid Vaccine, leaving her with significant vision and memory impairments- and she is a muso. She plays guitar, ukelele, piano, melodica, and is the singer in a little band. Music was a major part of her recovery. Despite her vision impairment, she lives a joyful life, filled with singing and music and the connection her band provides, and I firmly believe her almost daily music is what contributes to her happiness and sense of fulfillment.
Music and singing represent powerful yet accessible biohacking tools that engage nearly every region of the brain simultaneously. Research published in the National Institutes of Health shows that music possesses a remarkable capacity to induce transformative changes in the brain, fostering neuroplasticity and reshaping neural networks (32). A comprehensive 2025 literature review found that singing specifically improves verbal fluency, executive function, and episodic memory while creating structural changes such as increased white matter integrity and enhanced auditory-motor integration (34).
Harvard Medicine Magazine reports that music lights up nearly all of the brain, including the hippocampus and amygdala (which activate emotional responses), the limbic system (governing pleasure and reward), and the body's motor system (33). The stress-reduction benefits are equally impressive: studies show that listening to music can decrease cortisol levels by up to 60%, while music training brings about structural and functional brain changes that support social bonding, cognitive abilities, and language processing (35).
Whether you're actively playing an instrument, singing in the shower, or simply listening to your favourite playlist, you're engaging in a form of biohacking that enhances cognitive function, reduces stress, and promotes neuroplasticity. The beauty of music as a biohacking tool is its accessibility – no expensive equipment required, just the willingness to incorporate more music into your daily routine.

Once you've established solid foundations, intermediate biohacking strategies can provide additional optimisation benefits.
Sauna Therapy Regular sauna use is one of the most well-researched biohacking strategies available. Dr. Laukkanen's landmark Finnish studies, published in JAMA Internal Medicine, followed thousands of men for over 20 years and found extraordinary benefits. Men who used saunas 4-7 times per week experienced a 50% reduction in cardiovascular death risk, 66% lower dementia risk, and 65% lower Alzheimer's risk compared to once-weekly users (1,2).
The cellular benefits are equally impressive. A systematic review published by the NIH shows that regular sauna use increases heat shock protein production, enhances nitric oxide bioavailability, reduces oxidative stress, and improves cellular detoxification processes (3). Start with 10-15 minutes at 70-80°C and gradually build tolerance.
Cold Exposure and Ice Baths Controlled cold exposure triggers numerous beneficial adaptations, including increased brown fat activation, improved insulin sensitivity, enhanced immune function, and elevated mood through endorphin and norepinephrine release. Research published in the European Journal of Applied Physiology shows that regular cold exposure can increase metabolism and improve cold tolerance (20).
Grounding and Earthing Practices Direct skin contact with the earth's surface allows your body to absorb electrons, which may help reduce inflammation and improve sleep quality. While the research is still emerging, studies published in the Journal of Environmental and Public Health suggest that grounding can reduce cortisol levels and improve heart rate variability (21).
Breathwork Techniques Controlled breathing practices can rapidly shift your nervous system state, reduce stress, and improve oxygenation. Techniques like the Wim Hof method, box breathing, and coherent breathing have been shown to improve heart rate variability, reduce anxiety, and enhance overall resilience (22).
For those ready to take their optimisation to the next level, advanced biohacking technologies offer precise insights and targeted interventions.
Wearable Devices and Continuous Monitoring Modern wearables like Garmin watches, Oura rings, and continuous glucose monitors provide real-time data about your physiology. These devices can track sleep quality, heart rate variability, stress levels, and metabolic responses, allowing you to make data-driven decisions about your health protocols.
Advanced Biomarker Testing Comprehensive blood panels that go beyond basic health markers can reveal insights about inflammation, nutrient status, hormone levels, and metabolic function. Advanced testing might include inflammatory markers, nutrient panels, hormone assessments, mitochondrial function markers, glutathione and detoxification markers, methylation markers, microbiome testing, urinary organic acid testing, and heavy metal testing. These comprehensive assessments provide a detailed picture of your body's internal environment and guide personalised interventions.
Genetic Testing and Personalised Nutrition Nutrigenomics – the study of how genes interact with nutrition – allows for truly personalised health protocols. Genetic testing can reveal how you metabolise different nutrients, your risk for certain health conditions, and which interventions are most likely to benefit your unique genetic makeup.
Red Light Therapy and Photobiomodulation Red and near-infrared light therapy can penetrate tissues and stimulate cellular energy production by enhancing mitochondrial function. Research shows benefits for wound healing, muscle recovery, skin health, improved ATP production, and potentially cognitive function (23). NASA originally developed this technology for space missions, and it's now available for consumer use.

Neurofeedback Neurofeedback training uses real-time displays of brain activity to teach self-regulation of brain function. Research published in Applied Psychophysiology and Biofeedback shows that neurofeedback can improve attention, reduce anxiety, enhance sleep quality, and optimise cognitive performance (24). This non-invasive technique allows you to literally train your brain for better function.
Transcranial Photobiomodulation (tPBM) Transcranial photobiomodulation involves applying red and near-infrared light directly to the head to stimulate brain function. Studies suggest this technology can improve cognitive performance, reduce symptoms of depression, and enhance neuroplasticity (25).
Hyperbaric Oxygen Therapy (HBOT) HBOT involves breathing pure oxygen in a pressurised chamber, which increases oxygen delivery to tissues throughout the body. Research shows benefits for wound healing, neurological recovery, anti-ageing effects, and enhanced athletic performance (26). This therapy can stimulate stem cell production and improve mitochondrial function.
IV Vitamin Therapy Intravenous vitamin and mineral therapy bypasses the digestive system to deliver nutrients directly into the bloodstream. This approach can achieve much higher blood levels of nutrients than oral supplementation and is particularly useful for addressing deficiencies, supporting immune function, and enhancing recovery (27).
