What’s Biohacking: A Clear Guide to Optimising Your Body and Mind

What’s Biohacking? Biohacking is a way people try to change their bodies and minds to work better by using simple tools, tips, or lifestyle changes.

It means making small adjustments to improve health, energy, or focus in a personal and experimental way. For example, one person started tracking their sleep and diet to feel more alert during the day.

Dr Rhonda Patrick, a health expert, says, “Biohacking is about learning what your body needs and finding ways to meet those needs with science-backed methods.” Meanwhile, Dave Asprey, who popularised the term, describes it as “the art and science of upgrading your body for better performance.”

Many people are curious because biohacking puts control in their hands. It’s not magic, but a series of thoughtful changes anyone can try to see what works best for them.

What’s Biohacking?

Biohacking involves making changes to the body and mind to improve health, performance, or well-being. It includes a range of practices from simple lifestyle changes to using technology and biology to optimise human functions.

Some biohackers focus on nutrition and exercise, while others use gadgets, supplements, or even genetic tools. The goal is to take control of one’s biology through various methods.

Brief History of Biohacking

Biohacking began in the early 2000s as a DIY movement where people experimented with biology outside traditional labs. Early biohackers wanted to understand and improve their bodies using accessible tools.

It grew from a mix of computer hacking culture and biology, leading to home labs and community spaces. These groups shared techniques on tweaking body functions using diet, devices, and biology.

Notable moments include the rise of quantified self-tracking in the 2010s, where people started measuring health data. This helped biohacking become more mainstream and scientific.

Core Principles of Biohacking

Biohacking is based on three key ideas: self-experimentation, data tracking, and optimisation.

Self-experimentation means testing changes personally to see what works. This can involve trying new diets, exercises, or supplements.

Data tracking involves measuring things like sleep, heart rate, or blood sugar to understand effects. Many biohackers use apps or devices for this.

Optimisation aims to improve physical or mental functions. This might include better sleep, more energy, or sharper focus.

The practice emphasises gradual changes and informed decisions rather than quick fixes. Safety and understanding one’s own body matter most.

Types of Biohacking

Biohacking covers a range of methods aimed at improving the body and mind. It involves changing diet, biology, or technology to achieve better health or performance.

Nutritional Biohacking

Nutritional biohacking focuses on changing what a person eats and drinks. It includes diets, supplements, and fasting routines designed to improve energy, focus, or overall health. People track their food intake and adjust nutrients to suit their needs.

Common approaches include intermittent fasting, ketogenic diets, and taking vitamins or nootropics (substances believed to boost brain function). Many use apps or journals to measure how food affects their mood or energy.

This type of biohacking often involves trial and error. It is a popular starting point because it is non-invasive and easily controlled by the individual.

Biological and Genetic Biohacking

This type involves making changes at the biological or genetic level. It includes techniques like gene editing, DIY biology, or using smart drugs that alter brain chemistry.

Some biohackers experiment with CRISPR, a gene-editing technology, to change DNA. Others use pharmaceuticals or substances to improve mental clarity, memory, or focus.

These methods can involve higher risks and are less common outside scientific labs. Safety and ethics are important concerns here. People also use wearables to monitor body functions like heart rate or glucose levels.

Digital and Technological Biohacking

Digital biohacking uses technology to enhance the body and mind. This includes implanting devices, using apps, and linking to data platforms.

Examples are RFID chips implanted under the skin, which can unlock doors or store personal information. Others use brain-computer interfaces to control devices with thoughts.

Wearable technology like smartwatches and fitness trackers fall into this group. These tools gather data and help users make changes to improve health or cognitive function.

People in this group often focus on combining technology with biology for continuous improvement.

Popular Biohacking Methods

Biohackers use different approaches to improve health, focus, and energy levels. These methods often centre on changing diet, sleep habits, eating patterns, or mental performance. Each approach has specific practices backed by research or popular use.

Diet and Supplements

Diet is a common way to influence the body’s functions. Biohackers often choose whole, unprocessed foods rich in nutrients. They might follow diets like keto, paleo, or plant-based, depending on their goals.

Supplements play a big role in biohacking. Common choices include vitamins D and B12, omega-3 fatty acids, and antioxidants. People take these to fill nutritional gaps or support brain health, energy, and immunity. Some try more experimental supplements like nootropics, which aim to boost focus and memory.

Sleep Optimisation

Good sleep is essential for health and mental clarity. Biohackers focus on consistent sleeping times and creating a dark, quiet environment. Tools like blue light blockers and sound machines often help improve sleep quality.

Tracking sleep stages with devices like wearables is popular. This data helps users adjust habits to increase deep and REM sleep. Some also experiment with supplements like melatonin to fall asleep faster but use it cautiously. The goal is to wake up feeling rested and alert.

Intermittent Fasting

Intermittent fasting (IF) involves cycling between periods of eating and fasting. Popular schedules include 16:8 (16 hours fasting, 8 hours eating) or 5:2 (two low-calorie days in a week).

IF may help regulate blood sugar and boost metabolism. It also promotes a process called autophagy, where the body cleans out damaged cells. Biohackers value IF for potential benefits like better focus, weight control, and energy balance.

Cognitive Enhancement

Cognitive enhancement is about improving brain function and mental focus. Biohackers use techniques such as meditation, mindfulness, and mental exercises to sharpen attention and reduce stress.

Nootropics, or “smart drugs,” are another tool. These range from caffeine and L-theanine to prescription drugs like modafinil. Biohackers use these substances to enhance memory, alertness, and problem-solving skills, but with care due to possible side effects.

Physical exercise also supports cognitive health by increasing blood flow to the brain and releasing beneficial hormones.

Technology in Biohacking

Biohacking relies on different types of technology to monitor and improve bodily functions. These tools help gather data, track health, and sometimes make physical changes to the body.

Wearable Devices

Wearable devices are one of the most common tools in biohacking. They include smartwatches, fitness trackers, and heart rate monitors. These devices collect data on sleep patterns, activity levels, heart rate, and other vital signs. People use this data to adjust their habits, such as improving sleep quality or increasing exercise.

Many wearables now offer real-time feedback. This allows quick changes to diet, exercise, or stress management. The data is often synced with smartphone apps for easy tracking over time.

Implants and Sensors

Implants and sensors are small devices inserted under the skin or inside the body. They can monitor things like glucose levels or body temperature continuously. Some implants even stimulate nerves or muscles to improve certain functions.

People choose implants for more accurate data than wearables can provide. These devices can provide alerts or automatically adjust drug delivery, such as insulin for diabetes. However, implants carry risks including infection and require medical supervision.

Genetic Testing Tools

Genetic testing tools analyse a person’s DNA to identify traits, risks, and potential reactions to food or medicine. Companies offer home kits where users provide saliva samples to learn about their genetics.

The results can guide personalised changes in diet, exercise, or medication. These tools help biohackers understand their unique biology for better health choices. However, the accuracy and usefulness of some tests can vary. Users should interpret results carefully and consult experts when needed.

Risks and Ethical Considerations

Biohacking involves risks related to personal health and safety. It also raises questions about laws and regulations that apply to these practices.

Health and Safety Issues

Biohacking can cause physical harm if done incorrectly. For example, injecting substances or implanting devices without proper medical knowledge can lead to infections or damage.

Users might not know the long-term effects of new technologies or substances they use. Some biohacks have not been tested enough, making their safety unclear.

Mental health risks also exist. Changing brain function with certain biohacks might cause mood swings or unexpected psychological effects.

It is important for anyone attempting biohacking to be cautious and seek professional advice when needed. Ignoring safety can lead to serious health problems.

Regulatory and Legal Concerns

Biohacking often exists in a legal grey area. Many countries do not have clear laws regulating personal experimentation with biology.

Some practices might break local laws, especially those involving unauthorised drugs or devices. This could lead to fines or legal action.

Regulators struggle to keep up with new biohacking methods. This slow response means some unsafe practices remain unregulated for long periods.

Data privacy is another concern. Biohackers who use tracking devices collect sensitive personal information, which may not be properly protected.

Understanding these legal issues is crucial for anyone interested in biohacking. Knowing the rules helps avoid unwanted legal consequences.
