What Is Biohacking and How Does it Work?

Biohacking involves intentionally changing one's body and lifestyle to improve one's physical, mental, and emotional well-being. While some biohacking techniques may appear extreme or carry potential health risks, others are backed by scientific research and are considered safe when done responsibly. Biohacking allows individuals to take a proactive, personalised approach to self-improvement.

How Does Biohacking Work?

Biohacking works through a combination of experimentation, data tracking, and the application of science-based principles. The first step is understanding your body’s needs, which may vary from person to person. Everyone’s body responds differently, so biohackers typically experiment with different diets, workouts, and supplements to see what works best. Biohackers often use tracking devices and tools to measure key health metrics such as heart rate variability, sleep quality, glucose levels, and brain function. This data is then analysed to make informed decisions about lifestyle adjustments and interventions.

For example, a biohacker might use a wearable device to track their sleep patterns over a month. If the data shows that they’re not getting enough deep sleep, they may adjust their sleep environment, try relaxation before bed, or even experiment with sleep supplements.

Types of Biohacking

Biohacking can be divided into categories, ranging from simple lifestyle changes to more advanced, experimental methods. It often involves changing diet, exercise routines, and even biology to achieve goals.

Nutritional Biohacking

One of the simplest and most popular forms of biohacking relates to diet and nutrition. This can involve experimenting with different eating patterns like intermittent fasting, ketogenic diets, or personalised meal plans to find what works best for your body. The ketogenic diet has grown in popularity in recent years. In 2020, it was the most Googled diet in the United States, with 25.4 million unique searches. Fast forward to 2022 and the global market for ketogenic diet foods was valued at approximately $8.8 billion and is projected to exceed $12 billion by 2028

Genetic Biohacking

Genetic biohacking takes things further and involves manipulating your DNA to improve certain traits or reduce health risks. This can include techniques like CRISPR gene editing, which involves modifying certain genes. However, genetic biohacking is still in the experimental phase, with many ethical and safety concerns surrounding its potential use.

Body Hacking

Body hacking involves using technology or devices to improve physical performance. One of the most common examples are wearable technology like fitness trackers, heart rate monitors, and sleep trackers. In 2025, approximately 23% of the UK population use fitness trackers, equating to around 15.8 million individuals. This is predicted to increase to 29.68% by 2029.

Cognitive Hacking

Cognitive biohacking centres around improving brain function and mental performance. Practices in this category can include meditation and other mindfulness techniques to improve concentration and emotional well-being. Studies on mindfulness meditation began appearing in Dr. Jon Kabat-Zinn's Stress Reduction Clinic at UMass Medical Center as early as 1982. Since then, over 25,000 individuals have participated in his multi-week program, Mindfulness-Based Stress Reduction (MBSR), which teaches participants how to enhance their ability to manage stress, pain, and even chronic illness.

Sleep Hacking

Biohackers know that sleep is one of the most important factors in good health, and improving your sleep is one of the most effective ways to improve physical and mental performance. Research shows that Seven to nine hours of sleep are required for a healthy lifestyle. Poor-quality sleep can negatively impact your mental health and cognitive function and increase your risk of heart disease and diabetes. Long-term poor sleep can reduce your lifespan by 4.7 years for women and 2.4 years for men.

Sleep hacking involves using strategies to increase the quality and quantity of sleep. This could mean creating a sleep-friendly environment with blackout curtains, using sleep trackers to analyse sleep patterns, or experimenting with different sleep cycles. Techniques vary, one of the most common ones being the polyphasic sleep method—sleeping in short, strategic intervals.

The Benefits of Biohacking

Biohacking has seen significant growth in recent years, with the global market projected to reach $52 billion by 2027. This surge in popularity reflects an increasing interest in improving health, and performance through science-backed interventions. Here are some of the advantages biohacking can offer:

Improved Physical Performance: Many biohackers report better energy levels, faster recovery from exercise, and better fitness through personalised nutrition and exercise routines.

Better Mental Clarity: Cognitive biohacking, through techniques like meditation, and brain training, can lead to better focus, memory, and mental agility.

Increased Productivity: By improving sleep, energy levels, and mental clarity, biohackers may experience higher productivity and better decision-making

Risks and Ethical Concerns

While biohacking offers exciting opportunities for improving health, performance, and well-being, it also comes with risks and ethical concerns that must be considered. Relying too heavily on supplements or extreme methods of self-improvement can have unintended side effects, especially when done without medical supervision. It must also be noted that not all biohacking methods are backed by science. Claims of miracle supplements or devices that promise dramatic results should be approached with scepticism.

Genetic biohacking, especially self-experimentation and unregulated testing, poses serious public health risks. These include unsafe treatments, lack of proper consent, and the spread of unproven and potentially harmful therapies.
