The key to personal body optimisation

What is biohacking?

Biohacking is a combination of “bio” for biology and “hacking” for decoding. It refers to the optimization of our biological potential through adjustments. To influence your own biology, it is important to first develop an understanding of your body and its internal processes. Biohacking goes beyond mere decoding. It involves not only understanding but also deliberately influencing your own biology to optimise performance and personal well‑being.

A biohacker strives to become the best possible version of themselves by improving performance in a healthy way. Biohacking is about optimising nutrition, sleep, training, the brain and even interpersonal relationships. Body, mind and soul should be brought into balance and their full potential realised.

Biohackers follow a holistic health approach, not a one‑size‑fits‑all model. Typically they start with the three pillars of health: sleep, nutrition and movement. They analyse these fundamentals in detail, address each area and test different methods to optimise them as much as possible.

Such an approach brings benefits across many areas of life: it increases everyday energy, improves self‑awareness, strengthens physical and mental resilience, reduces disease risk, raises productivity and concentration, and helps achieve personal goals.

What role does sleep play in biohacking optimisation?

The first step in any biohacking plan is improving sleep. Because our body is almost as active during sleep as it is when awake, good sleep hygiene affects all aspects of life. Our brain uses different sleep phases to process, sort and make room for new information.

If you regularly wake up in the middle of the night and struggle to fall back asleep, you may have a disruption to your sleep rhythm. In our hectic modern world, good sleep hygiene is therefore especially important.

How do nutrition and hormones influence biohacking strategies?

The next crucial step is to balance the hormonal system. According to neuroendocrinologist JoAnn Manson from the University of California (UCLA), hormones and the body’s circadian rhythm influence almost every aspect of health – from mood to weight to the immune system. Training and a balanced diet not only help control weight but also influence hormonal and physiological state.

By taking responsibility for diet, exercise and daily habits, long‑standing unhealthy eating patterns can be reversed and the whole hormonal system positively affected. Nutrition and stress can impact hormone function and overall well‑being. If balance is not maintained, hormones fall out of alignment.

What role does exercise play in biohacking?

Equally important are movement and sport. Studies suggest that physical activity can stimulate the formation of new nerve cells in the brain, so‑called neurogenesis. Scientists believe that exercise raises the concentration of growth factors in the blood. These factors may cross the blood‑brain barrier and promote the generation of new neurons.

An established guideline in biohacking is the movement pyramid. It aims to activate and multiply mitochondria, the body's powerhouses, which are essential for adequate energy supply. The movement pyramid is arranged from bottom to top into four tiers: everyday movement, endurance, strength training and sedentary leisure.

Are there risks or limits to biohacking?

The biohacking motto is: the more you know about your body, the better. Information is the basis for optimisation. That is why people turn to the latest biohacking gadgets to optimise themselves deliberately.

An alternative stream of biohacking even explores the desire to modify DNA. DNA hackers analyse their own hereditary information to detect mutations in their genome. They study epigenetics and use DNA tests to decode ancestry. The CRISPR technology developed in 2012 (Clustered Regularly Interspaced Short Palindromic Repeats) is an example of a tool used to edit and manipulate genes. It repurposes a bacterial defence system against viruses as a versatile gene‑hacking tool. This area of biohacking is certainly the most extreme.

At the same time a biohacker is their own motivation coach. Personal interest in problem‑solving and personal growth is required. Weighing effort against benefit and a willingness to experiment are essential, because progress comes through change.

The downside of the self‑optimisation hype online is that there are no clear guidelines or control bodies to check dubious websites and sources. It is therefore wise to avoid supposedly promising chips, implants, blood transfusions or medications. When in doubt, discussing your goals with a doctor is recommended.

Tips and tricks for better well‑being, higher performance and maximum satisfaction

• Eating slowly and mindfully benefits digestion. Fast, distracted eating burdens the gut and impairs digestion. It helps to switch off the TV or laptop while eating and consciously enjoy the meal. Chewing each bite about 30 times also supports digestion.
• Minimise consumption of dairy and gluten products, as they can cause significant digestive issues. Consider lactose‑free alternatives such as plant‑based milks (rice, soy, almond, pea) or lactose‑free milk.
• A popular biohacking breakfast is so‑called Bulletproof Coffee, a blend of coffee, butter and MCT oil. The healthy fat from butter keeps you full until lunch — almost without carbohydrates. The caffeine stimulates circulation and MCT oil can boost fat burning. Bulletproof Coffee also works well as an energy boost about 90 minutes before training. To prepare it, place 2 tablespoons of butter and 2 tablespoons of MCT or coconut oil in a large cup. Pour 2 cups of filter coffee over it and blend with a milk frother, immersion blender or mixer until frothy.
• Turmeric has anti‑inflammatory and digestive benefits. The active ingredient curcumin is comparable to that in aspirin. Bones and joints may also benefit from this remedy. Turmeric has been shown to lower blood pressure and cholesterol levels. For the famous Golden Milk of biohackers, peel 4 pieces of turmeric (about 1 cm each) and 1 piece of ginger (about 1 cm). Blend these with 1 tsp coconut or MCT oil, 1 tbsp agave syrup, 600 ml rice milk or another plant drink (e.g. soy or coconut), 1 tsp black pepper, 1 tsp cinnamon and 1 tsp cardamom at high speed. Then simmer in a pot for about 5 minutes.
• Enzymes are natural substances that can help the body process nutrients. If the gut flora is already damaged, probiotics help. They regenerate the intestinal lining and normalise the gut environment.
• Omega‑3 fatty acids from krill or algae oil, vitamin D3 & K2 and nootropics (Brahmi, natural L‑theanine from green tea extract, ginseng, ginkgo, CDP‑choline and alpha‑choline) are standard supplements for a biohacker.
• It is particularly important to drink enough water. Ideally start the day with one to two glasses of water in the morning, optionally with lemon and salt to rebalance electrolytes after sleep.
• It is important to deliberately reduce stress and find relaxation. Breathing techniques and guided meditation can help you connect with your body and calm the mind.
• In today's modern world we face an overload of information and tasks that, together with physical strain, fatigue and occasional depression, can lead to stress. In such situations a digital detox is recommended — regularly switching off electronic devices like laptops, PCs, smartphones, tablets and TVs. Start small, for example by turning off your smartphone for an hour.
• If you choose biohacking, try to improve your sleep hygiene and align as much as possible with your internal clock. The bedroom should be dark and not too warm (16 to 18 degrees). To encourage melatonin production, avoid artificial light 1 to 2 hours before bedtime.
• Exposure to blue light via the retina tricks your body into thinking it's daytime. Your circadian rhythm keeps you awake and focused. If artificial blue light reaches your eyes after sunset, the production of the sleep hormone melatonin is inhibited. That means you cannot fall asleep. Blue‑light‑filtering glasses can block the blue light so you fall asleep faster and wake up refreshed the next morning.
• It is known that the average person has about 60'000 thoughts per day, of which up to 85% are negative. That presents a large optimisation potential. Phrases like “I can't” or “I'm not good enough” should be removed from your vocabulary. Positive affirmations can also be used to transform negative thoughts into positive ones.
• Regular movement has very positive effects on gut health and general well‑being. The foundation is 30 minutes of daily movement. You don't need to sweat excessively or strain yourself during this activity. It's simply about moving. This could be a walk, a gentle hike, dancing, gardening or commuting by bicycle, for example.
• Add endurance training of 3 to 5 sessions of 20 minutes per week. Here effort and sweating are expected. Sports such as running, skiing, tennis, various ball sports or mountain hiking that build endurance, coordination and skill belong to this category.
• Above that is the strength training level, 2–3 times per week for at least 10 minutes. This includes activities such as climbing, swimming, gymnastics, yoga, gym workouts or calisthenics. The pyramid's top is sedentary leisure — less is more here. If you spend most of your workday sitting, avoid sedentary pastimes in your free time.
• In cold thermogenesis, the body oxidises brown fat due to cold, producing heat that is distributed around the body via the blood. A cold morning shower is a simple way to benefit from cold thermogenesis.
• Walking barefoot strengthens foot muscles and can relax the whole body. Skin contact with the Earth's surface may provide various benefits through grounding. The uptake of free electrons is said to have antioxidant effects and the Earth's magnetic field is believed to be particularly energising and balancing when walking barefoot.
• Forest bathing has lasting effects on mood and well‑being. Time spent in the forest helps reduce stress and triggers the release of anti‑inflammatory messengers. Fresh forest air increases oxygen saturation.
• Gratitude has an immediate effect on well‑being. Writing down three things you're grateful for each evening is an effective psychological strategy to increase happiness, satisfaction and love.
• Biohacking is a highly individual approach — what helps one person may not suit another. It's important to listen to your body's needs and reactions and not overdo it to maintain a healthy balance and well‑being. Everyone should find their own biohacking path that fits their lifestyle and goals.

Biohacking opens the exciting possibility to shape, step by step, the optimal version of yourself. Start today to take back control of your life and feel great in every respect!
