Self-improvement or danger? Doctor reveals shocking facts about biohacking

What is biohacking

According to the doctor, biohacking is a broad concept, usually referring to a person’s attempts to independently improve health, well-being, or performance. It includes lifestyle changes, nutrition adjustments, or interventions in the body’s functions.

Overall, biohacking encompasses very different approaches, from completely safe habits to potentially risky experiments with uncertain results.

“People turn to biohacking for many reasons: they want to improve their health, correct perceived flaws, gain more control over their bodies, enhance productivity, or extend life,” the doctor wrote.

Examples of biohacking

• Intermittent fasting – practiced for millennia, it has recently become popular among biohackers as a way to “reset” or improve metabolic states. Fasting has proven benefits: weight control, reduced risk of diabetes, and cardiovascular health improvements.

• Nootropics or “smart drugs” – these include medications, supplements, drinks, or foods that are claimed to boost brain function and cognition, such as creatine or caffeine. Prescription nootropics (used for ADHD or Alzheimer’s) should only be taken under a doctor’s supervision, as misuse can cause anxiety or impair cognition.

• Wearable technology – smartwatches, fitness trackers, and other gadgets help monitor and analyze health metrics, sleep, and physical activity. The next step includes devices implanted into the body to collect detailed data on biological functions and fitness, according to Shvets.

Popular biohacking directions

• Experimental bioengineering (DIY biology) – scientists share biohacking techniques with non-experts, allowing more people to experiment on themselves outside labs. However, this approach raises health concerns.

• Nutrigenomics – studies how diet affects gene expression, activating or deactivating genes to influence physiological processes and disease risks. The goal is to create optimized individual nutrition plans for health or disease management.

• Grinders – involve implanting devices under the skin and using technology to modify the body.

What research says

Shvets noted that biohacking is barely regulated, and many people do not report their results. Online communities share discoveries, but the accuracy of many self-experiments is uncertain.

Animal studies in nutrigenomics show that fructose can alter key gene regulation aspects, affecting how infections develop into diseases. Fructose also impacts metabolism, inflammation, and immune system function.

Methods that work

• Intermittent fasting – eating within specific time windows (e.g., 12:00–20:00) and fasting outside them. Benefits include reduced body fat, lower blood pressure and heart rate, and reduced inflammation.

• Cold water therapy – immersing in water below 15 °C. Potential benefits include improved cardiovascular, immune, endocrine, and mental health. However, risks include cold shock, hypothermia, and sudden death.

• Caffeine – increases focus and productivity, but excessive intake can cause high blood pressure, heartburn, or headaches.

Risks of biohacking

Many biohackers experiment without proper regulation or precautions. Advice from blogs and social media should not be followed blindly. Before trying a new sleep, diet, or exercise routine, consult a doctor or certified specialist.
