Biohacking has taken a massive jump in 2025, giving people control over their health like never before. From stress reduction to sleep enhancement, the latest technology puts powerful results just a tap away. Discover the best biohacking technology in 2025!
Pulsetto is a wearable device that uses vagus nerve stimulation (VNS) to promote relaxation and reduce stress and anxiety. By targeting the vagus nerve with gentle electrical impulses, Pulsetto can help induce a state of calm, making it easier to fall asleep and stay asleep.
Advantages of Pulsetto:
Stress Reduction: Experience significant relief from daily stress by activating your vagus nerve and shifting your body into a "rest and digest" state.
Improved Sleep: Pulsetto supports restful sleep by calming your nervous system, helping you wake up refreshed and energized.
Enhanced Mental Clarity: By promoting relaxation, Pulsetto aids in sharpening focus and reducing brain fog.
Digestive Health Support: Vagus nerve stimulation positively impacts the gut-brain connection, aiding digestion and reducing bloating.
Chronic Health Support: Pulsetto offers support for individuals managing chronic stress, anxiety, and fatigue, helping to improve their quality of life.
Using Pulsetto is simple and takes just 4 minutes to start feeling the effects. Here's how it works:
Apply a generous amount of gel to your neck or directly onto the electrodes.
Place the device on your neck.
Pair it with the Pulsetto app on your smartphone.
Choose your desired program and start the device through the app.
The device creates a gentle, pleasant vibration or tingling sensation in your neck area. This stimulation helps activate your parasympathetic nervous system, leading to a calmer, less stressed state.
These are devices worn or placed on the outer ear (auricle) that combine sensing, stimulation, and sometimes human-computer interfacing. They are rising in prominence because the ear provides a convenient, discreet site with rich neural and vascular connections, facilitating both neuromodulation (affecting mood, stress, sleep) and sensing (physiological, biochemical). Advances include flexible, conformable microelectronic materials, hydrogels, liquid metals, and piezoelectric films so that they are comfortable, skin-friendly, and capable of continuous usage. These devices can serve multiple functions at once (monitoring, data collection, stimulation, user interface), which makes them powerful tools for self-optimization. Challenges include ensuring reliable signal quality, battery life (or power delivery), and making sure stimulation is safe and tuned correctly. Also, regulatory approval and long-term safety are still being studied. But as of 2025, this category looks like a frontier: merging wearables, neurotech, and personal health in a seamless form.

Smart Contact Lenses with Self-Powered Sensing & Energy Harvesting
One of the emergent technologies in 2025 is smart contact lenses capable of self-powered operation and real-time health monitoring. A recent academic work describes designs using microfabricated loop antennas (operating in the ~900 MHz–1.1 GHz band) for communication, combined with energy harvesting from ocular sources (e.g. tear salinity or eyelid motion) to avoid the need for bulky power sources. These lenses could continuously monitor biomarkers in tears, potentially detecting inflammation, stress indicators, or metabolic markers; also possibly enhancing vision functionality (e.g. light filtering, augmented reality overlays) in future versions. The advantages include being nearly invisibly integrated, offering continuous data, minimal interference with everyday activities, and reduced dependency on external charging. The limitations are still significant: material biocompatibility, comfort, ensuring stable sensors over long periods, maintaining safety (especially for eye tissue), miniaturization challenges, potential risk of infection, data security, and ensuring reliable wireless communication without health risk. Nonetheless, smart lenses are one of the most exciting emerging biohacks in 2025.

Quantum Biosensors on Chip
These are ultra-sensitive, chip-scale biosensors combining quantum technologies (like quantum dots, nitrogen-vacancy centers in diamond, etc.) with photonic or microelectronic circuits to detect biochemical signals at extremely low concentrations. The idea is that such sensors can detect subtle changes in biomarkers (e.g., early disease markers, oxidative stress, metabolites) long before traditional methods can. Because of the quantum sensitivity, these sensors promise high specificity (few false positives/negatives) and low noise. They can be miniaturized, possibly incorporated into wearables, implants, or patches. The challenges: engineering complexity, cost, integrating into user-friendly form factors, ensuring stability, dealing with environmental noise, providing power, and regulatory or safety hurdles. As of 2025, many are still in research/prototype stage, but they represent a likely direction for next-generation sensing in longevity and health optimization.
Wearables that continuously monitor physiological signals (sleep stages, HRV, body temperature, activity, respiration) combined with biological age assays are well entrenched in 2025. Products like Oura Ring offer precise tracking of sleep, recovery, and rest vs. activity balance. Biological age tests such as GlycanAge use biomarkers (glycans, immune system markers) to estimate how “old” your body really is, which may differ from chronological age. These tools empower users to see patterns, adjust behaviour, and potentially slow aging processes via lifestyle tweaks (sleep hygiene, nutrition, stress management). Strengths include fairly wide availability, non-invasiveness, accumulating longitudinal data, and real-world feedback. Limitations include: the metrics are probabilistic rather than deterministic; interpretations can vary; data privacy concerns; also sometimes feedback loops (you track data, but don’t know what best to do with it) are weak. But overall, this tech is mainstream in biohacking in 2025 and continues to improve, especially as algorithms, sensor accuracy, and integrative platforms evolve.
Biohacking is the practice of making small, measurable changes to your biology to improve health, performance, or well-being. It ranges from simple lifestyle tweaks (sleep, diet) to using wearables, supplements, or even DIY biology.
Is biohacking the same as self-experimentation?
They overlap. Self-experimentation is a core part of biohacking, trying changes, measuring results, and iterating, but responsible biohacking emphasizes safety, evidence, and tracking.
Quantified self (measurement-driven changes using data).
DIY biology / more advanced (lab experiments, genetic tools, high risk and usually not recommended for amateurs).
What are easy, low-risk biohacks I can try now?
Start with: consistent sleep schedule, 20–30 minutes of morning sunlight, hydration, 12–16 hour fasting window (if medically OK), daily movement, and removing blue light before bed.
Are biohacking supplements safe?
Many over-the-counter supplements are safe when used sensibly, but quality varies and interactions with medications are possible. Always check with a healthcare professional before starting anything new.
What devices are popular with biohackers?
Fitness trackers, sleep trackers (actigraphy), continuous glucose monitors (CGMs) for some users, HRV monitors, and light therapy devices. Devices help quantify effects, but data needs correct interpretation.
How do I measure if a hack is working?
Define 1–2 clear metrics (sleep duration/quality, resting HR, mood, productivity, body weight, blood glucose). Measure baseline, implement the change, then compare over time. Use short trials (2–6 weeks) and controlled conditions when possible.
Is intermittent fasting considered biohacking?
Yes, it’s a widely used nutritional biohack that can affect metabolism, body composition, and sometimes cognitive clarity. Its suitability depends on individual health, medication, and goals.
Can biohacking help with sleep?
Yes. Simple evidence-based sleep hacks include fixed wake/bed times, reducing evening light exposure, avoiding stimulants late in the day, and using a cool, dark sleep environment. Track improvements using a sleep tracker or subjective sleep diary.
Is cold exposure (cold showers, ice baths) useful?
Many report benefits like increased alertness, mood boost, and resilience. Start gradually (cold showers for 30–60s) and avoid extreme protocols if you have cardiovascular issues. Safety first.
What is HRV, and why do biohackers care?
Heart Rate Variability (HRV) is the variation in time between heartbeats. Higher HRV generally indicates better autonomic balance and recovery. Biohackers use HRV to monitor stress and recovery.
Can biohacking increase longevity?
Some biohacks (exercise, good sleep, healthy diet, avoiding smoking) are proven to improve lifespan and healthspan. Parties claiming miracle longevity fixes should be treated skeptically.
What are the risks of biohacking?
Overdoing supplements, ignoring contraindications, misinterpreting data, or performing high-risk experiments without professional oversight. Start small, document changes, and consult professionals where appropriate.
Should I tell my doctor about my biohacking experiments?
Yes. Sharing relevant changes (new supplements, major diet shifts, devices like CGMs) helps your clinician give safe advice and avoid harmful interactions.
Absolutely. The Pulsetto device itself is fully certified by the FCC and CE, which means it complies with strict laws and is approved for use for general health. It uses the lowest bluetooth energy, called “ultra low radiofrequency energy” (ULRE), which is safe for use on the body.
It’s also clinically tested and designed for daily use. Since it’s non-invasive and drug-free, there’s no risk of dependency or side effects. You can use it once a day or several times depending on your needs, before bed, during a stressful moment, or to reset between work tasks. It’s safe, simple, and built for consistency, so the more you use it, the better your nervous system functions over time.
Above all, Pulsetto devices have performed more than 1.5 million simulations already with zero side effects.
How fast will I feel results?
Most users feel noticeably calmer within just 4 minutes. That’s because Pulsetto uses clinically proven vagus nerve stimulation to rapidly shift your nervous system out of fight-or-flight mode and into rest-and-digest. Unlike supplements or meditation apps, there’s no need to wait weeks for subtle changes, relief starts almost immediately. Over time, regular use also strengthens your vagal tone, making you more resilient to stress and better able to stay calm throughout the day.
What does it feel like?
It feels pleasant! Most users describe it as a slight tingling sensation, or a tickle. It’s designed to relax you, so it’s completely pain-free — otherwise it wouldn’t be very calming, would it!
What exactly is the vagus nerve, and why does it matter?
The vagus nerve is the longest cranial nerve in your body, and it plays a crucial role in regulating your mood, stress, digestion, heart rate, and sleep. It’s like your body’s internal switchboard for calm and recovery. Pulsetto gently stimulates this nerve to activate the parasympathetic nervous system, helping you slow down, relax, and restore balance. It’s the same nerve doctors stimulate in clinical settings to treat mood and anxiety disorders, but Pulsetto brings this powerful science home.
Can Pulsetto help me sleep better?
Yes, Pulsetto helps you fall asleep faster, stay asleep longer, and wake up more refreshed. By stimulating your vagus nerve, it activates your parasympathetic nervous system (the one responsible for rest and recovery), helping your body power down naturally. It’s a non-invasive, drug-free solution that works with your body’s own biology. Whether you struggle with racing thoughts, trouble falling asleep, or restless nights, Pulsetto helps create the calm, balanced state your body needs to enter deep, restorative sleep.
What’s included in the Pulsetto App? Is it free?
Yes, the app is 100% free and comes included with the Pulsetto device. It offers 5 unlimited stimulation programs for sleep improvement, nervousness, stress reduction, burnout, and pain management.
The app works with both iOS and Android. It also has a specialized Sound Library filled with sounds specifically designed for Pulsetto, which improve the overall experience.
Do I need to be tech-savvy to use it?
Not at all. Pulsetto is designed to be incredibly easy to use. Just place it around your neck, open the free app, and start your session. The app walks you through everything, from choosing the type of session to adjusting intensity levels. Even if you're not into tech, you’ll find it intuitive and seamless. It’s as easy as putting on a pair of headphones and pressing play, except instead of sound, you're stimulating calm.
Can Pulsetto really help with stress and anxiety?
Yes, and that’s where Pulsetto truly shines. Chronic stress and anxiety are often caused by an overactive sympathetic nervous system (the fight-or-flight response). Pulsetto works by activating the opposite system, the parasympathetic, which signals to your body that it’s safe, helping you relax almost instantly. Whether you're managing daily overwhelm or deeper emotional stress, Pulsetto gives you a powerful tool to self-regulate in a natural, consistent way. It’s peace of mind at the push of a button.
How is Pulsetto different from other wellness tools like meditation apps or supplements?
Meditation apps and supplements can help, but they often take time, focus, and commitment. Pulsetto works physically, not just mentally. By directly stimulating the vagus nerve, it taps into your nervous system’s core functions, creating a fast and reliable physiological shift. You don’t need to “get in the zone” or wait weeks for effects. It’s consistent, clinically supported, and easy to use daily. Pulsetto is not just a wellness tool, it’s a nervous system upgrade.
What if I don’t struggle with anxiety or sleep, can Pulsetto still benefit me?
Yes! Even if you’re not actively struggling, Pulsetto can still improve your overall health and performance. Regular vagus nerve stimulation boosts focus, sharpens mental clarity, supports digestion, reduces inflammation, and even enhances athletic recovery. Think of it like exercise for your nervous system, the more you use it, the stronger and more balanced it becomes. Pulsetto is perfect for anyone who wants to feel more grounded, energized, and resilient in their everyday life.
Who is Pulsetto designed for?
Pulsetto is for anyone who feels overwhelmed, stressed, tired, anxious, or sleep-deprived, basically, most people today. It’s especially helpful for busy professionals, parents, high-performers, and anyone seeking a non-medicated, science-backed way to feel better.
