"Biohacking" has become a catch-all word that means very different things to different people. To one person, it's a cold plunge before work. To another, it's a $50,000 longevity protocol. The term has gotten muddy enough that it's worth defining what it actually refers to, and just as importantly, what it doesn't.
The original idea
The word "biohacking" emerged in the early 2010s, mostly online, used by self-experimenters who wanted to apply an engineer's mindset to their own biology. The premise was simple: treat the body like a system, measure inputs and outputs, and adjust based on data.
That's it. No supplements required. No expensive gear. The original idea was about self-knowledge through measurement.
What biohacking actually includes
At its most useful, biohacking is an umbrella term for evidence-informed practices people use to improve how they feel and function. The categories tend to be:
- Sleep optimisation: tracking, lighting, temperature, timing.
- Nutrition: meal timing, macro tracking, food sensitivities, glucose response.
- Movement: zone 2 cardio, strength training, daily activity.
- Recovery: sauna, cold exposure, breathwork, stress regulation.
- Cognitive: focus protocols, meditation, supplementation.
- Diagnostics: bloodwork, continuous glucose monitors, wearables.
What it isn't
Three common misconceptions worth clearing up:
- It isn't a shortcut. The most useful biohacking practices are unglamorous: consistent sleep, regular exercise, whole foods, sunlight. They work because they're done consistently, not because they're novel.
- It isn't anti-medicine. Real biohackers work with their doctors, not around them. Bloodwork interpretation, hormone panels, and metabolic testing are all part of conventional medicine.
- It isn't about extreme protocols. Cold plunges and three-day fasts get the headlines, but the average effective biohacker is mostly improving their sleep, walking more, and eating fewer ultra-processed foods.
The tension worth naming
Biohacking has a marketing problem. Because the word is unregulated, it's used to sell anything from a $30 supplement to a $300,000 longevity package. The practice itself is sound. The hype around it is what makes the field hard to navigate.
The way through is to keep asking two questions: What's the evidence? and What's it actually changing in my body? If you can't answer both, the protocol probably isn't worth your time.
The Reset takeaway
Biohacking, properly understood, is just applied curiosity about your own physiology. The basics, sleep, movement, food, sun, stress, are still the highest-leverage practices. Everything else is optimisation around those.
