In this episode of the Biohacker's Podcast, Teemu Arina speaks with Eduard de Wilde on peakspan, the idea of extending the years you can keep doing what you love, how he healed from a medication-induced anxiety disorder through lifestyle, the 20/80 rule and five dials of his book More Good Years, and why trends in your data matter more than single numbers.Check https://hololifesummit.com for upcoming events & tickets.Devices, supplements, guides, books & quality online courses for supporting your health & performance: https://hololifecenter.comEduard de Wilde, author of More Good Years and founder of LiveHelfi and NoordCodeEduard de Wilde is a Dutch entrepreneur, biohacker and Certified Bulletproof Coach. After the antimalarial Lariam left him with a severe panic and anxiety disorder in 1999, he rebuilt his health through lifestyle and has spent the past two decades bringing biohacking to a wider audience. He founded LiveHelfi, one of Europe's largest biohacking webshops, and the supplement and functional food brand NoordCode, and is also behind a coach training school for health optimization professionals. His book More Good Years is about peakspan: keeping the things you love in your life for as long as possible. He gives a keynote on the book at HOLOLIFE Summit in Amsterdam on 14 and 15 November 2026.Website: https://www.dewilde.comInstagram: @eduarddewilde- Peakspan shifts the goal from adding years to extending the period in which you can still do the things you love.- Many people say they care less about when they die than about staying able to enjoy their favourite activities, which makes function a more motivating target than lifespan alone.- A 20/80 approach focuses on the few basics that deliver most of the benefit, while advanced protocols remain optional for enthusiasts.- Regular bedtimes and a stable circadian rhythm are a foundation that supports energy, mood and recovery.- Strength training, intervals, cardio and especially mobility help counter age-related muscle loss and keep everyday movement possible later in life.- Cooking whole foods, limiting ultra-processed products and avoiding large glucose swings covers much of what good nutrition requires, and Mediterranean-style eating has broad research support.- A system of default habits with room for occasional indulgence tends to be more sustainable than strict perfectionism, which often ends in rebound.- Mental wellbeing and relationships matter alongside the body, from stress regulation to handling difficult people and deeper emotional work.- Health data is most useful when you follow long-term trends such as heart rate variability rather than reacting to single readings, and it should support rather than override how you feel.- Small, consistent habits woven into ordinary days, such as taking the stairs instead of the escalator, compound over decades into more good years.00:00 - Cold Open00:56 - Meet Eduard de Wilde02:12 - Lifespan, healthspan and peakspan03:41 - Lariam, Cameroon and a panic disorder05:45 - The psychiatrist's verdict06:13 - Healing through lifestyle08:56 - The 20/80 rule10:07 - Biohacking for non-biohackers13:33 - How peakspan differs from healthspan15:17 - Joyspan and reframing wellness16:50 - The five dials of More Good Years18:25 - Biohacking 3.0: three layers of the mind20:41 - Hacking the ego21:55 - Nutrition tests and the nocebo effect25:32 - A system of habits beats perfection27:03 - Sleep, movement, mobility and nutrition29:41 - Biohacking built into daily life33:44 - What makes people take charge of their health35:19 - His mother, the original biohacker38:41 - Technology that simulates nature39:48 - Infrared, HeartMath and HRV trends42:23 - The tests worth doing46:07 - When to overrule your data48:24 - Informed consumers and the medical system52:10 - Where to find the book and products

She speaks at HOLOLIFE Summit in Amsterdam on 14 and 15 November 2026 with the talk I'm A Holosexual, Are You?Website: https://betterlover.comInstagram: @susanbratton- Sexual health belongs in the longevity conversation, since reproductive and sexual function tend to track overall vitality.- Sex does not have to decline with age, because technique, communication and intimate wellness are skills that can keep improving over a lifetime.- Learning a structured practice first, much like a yoga or martial arts form, makes it easier to explore and improvise later.- Simple communication habits, such as sharing the best moment of a shared experience and giving audible feedback, help partners understand what feels good.- Performance anxiety is common and can affect erections and orgasm, and it often stems from not knowing what to do rather than from a physical problem.- Arousal depends on blood flow in every body, so circulation, nitric oxide and nutrition deserve attention as people age.- Options for restoring sexual tissue range from low-cost pumps and red light to lasers, PRP and stem cells, but evidence varies and the right choice depends on the problem and the budget.- Standard STI screening often misses infections such as Mycoplasma genitalium, and incubation periods mean the timing of a test matters as much as the panel.- Botanicals such as maca, fenugreek, tribulus, tongkat ali and cacao may support libido for some people, effects vary and cycling may help, while some, like yohimbe, carry real cardiovascular risks.- Treating intimacy as a learnable, lifelong part of health and relationships may support connection, wellbeing and a fuller life.00:00 - Cold Open00:48 - Sexual Health as a Longevity Marker02:42 - From Silicon Valley Executive to Intimacy Expert04:21 - The Upward Pleasure Spiral05:08 - The Orgasmonaut06:07 - Better in Bed With Age07:19 - Why Intimacy Needs a Protocol10:30 - Retention, Ejaculation and Chemistry13:19 - Tantra Versus Practical Lovemaking15:27 - Bedroom Communication and Moaning17:42 - Autoeroticism and Narcissism19:20 - Performance Anxiety21:04 - Partners, Polarity and Synergy25:29 - The Sex Life Bucket List28:39 - Risks, Porn and Dopamine31:23 - Sexual Biohacking and Reversing Atrophy33:50 - Vaginal Lasers, Stem Cells and Red Light37:21 - Matching Therapies to Your Budget39:42 - Pleasure Tools and Desensitization Myths43:49 - Sex Tech and AI46:51 - Quantified Intimacy49:21 - Ovarian Health and Menstruating at 6551:26 - STI Testing and Fluid-Bonded Circles58:41 - Aphrodisiacs and Botanicals1:05:20 - Becoming Holosexual: Her Amsterdam Talk1:07:06 - Sexuality and a Whole Life1:08:32 - A Fantastic Time to Be Alive

The company was founded by his mother, Yuko, who holds the device patent, and its hydrogen and oxygen inhalation systems are used in more than 200 clinics and wellness locations in Japan. He began his career in detoxification and rehabilitation programmes, later founded a language school in Japan, and has led the development of Japanese HHO inhalation systems since 2020. In this conversation he explains how the device and its goggles work, why the company talks about atomic rather than molecular hydrogen, and what it means to approach health through the Japanese idea of ikigai.Website: https://www.miwakankyo.comInstagram: @miwakankyo and @hanajimba- Hydrogen is the smallest molecule in nature, which is why it is studied as an antioxidant that may reach tissues other compounds cannot, although most human evidence so far comes from small trials.- Hydrogen and oxygen (HHO) inhalation devices deliver a mix of roughly two parts hydrogen to one part oxygen, which differs from breathing pure molecular hydrogen gas.- Claims that atomic or nano-sized hydrogen outperforms molecular hydrogen rest mainly on manufacturer measurements and early research and still need independent, peer-reviewed confirmation.- Selective neutralisation of the hydroxyl radical, one of the most damaging reactive oxygen species, is the most widely cited mechanism behind hydrogen's antioxidant effects.- Eye and skin uses such as hydrogen goggles and hydrogen baths are an interesting area, but published human data on them remain limited.- Protocols that mobilise heavy metals are best paired with binders and medical guidance, because mobilised metals can redistribute in the body before they are excreted.- Hydrogen generators differ widely in electrode material, gas output and safety engineering, so device quality matters as much as the idea itself.- Hydrogen is a flammable gas, which makes documented safety testing an important criterion when choosing a device.- The effects on autoimmune disease, autism and scars mentioned in the conversation are preliminary or anecdotal and should not replace medical diagnosis or treatment.- Lasting health habits, like the Japanese idea of ikigai, grow from a sense of purpose and daily craftsmanship rather than from quick fixes.00:00 - Cold Open00:32 - Welcome01:44 - Why Breathe Hydrogen?03:23 - Goggles, Eyes and the Brain05:11 - The Family Business Behind My Mother06:33 - Atomic vs. Molecular Hydrogen11:15 - Use Cases: From Jet Lag to Recovery12:05 - Eye Recovery in National Volleyball14:37 - Lymphatic Flow and the Cranium16:58 - How Much Is Too Much?18:18 - Biomarkers and Heavy Metals22:42 - Hydrogen Baths, Skin and Hair26:02 - Energy, Mitochondria and ATP27:09 - Cheap Hydrogen Bottles vs. Medical Devices32:00 - Inside the Machine34:27 - Inflammation and Immunity37:14 - Wound Healing and Gut Health42:00 - Children's Health45:08 - Why Japan Takes Hydrogen Seriously46:09 - Dr. Emoto and the Structure of Water49:01 - Meet Miwa at HOLOLIFE Summit49:20 - Why "My Mother"?50:27 - Durability and Maintenance53:19 - The Japanese Meaning of Ikigai58:10 - Closing

In this episode of the Biohacker's Podcast, Teemu Arina speaks with Matt Maruca, founder and CEO of Ra Optics, to examine the critical role light plays in human biology.Matt reframes light as a primary biological input that regulates circadian rhythm, hormone production, mitochondrial efficiency, and sleep quality. He explains how excessive exposure to artificial blue light (especially after sunset!) disrupts melatonin release and contributes to metabolic dysfunction, poor recovery, and chronic fatigue. Ra Optics was founded to address these challenges through scientifically engineered eyewear that selectively filters harmful wavelengths while preserving beneficial light.The discussion moves beyond blue light fear-mongering into practical circadian strategy. Matt emphasizes the importance of bright, full-spectrum light exposure during the day to anchor biological timing, while advocating warm, low-intensity lighting in the evening to support sleep. He highlights the role of red and near-infrared light in mitochondrial energy production and recovery, and cautions against low-quality lenses that distort vision or block indiscriminately.Looking forward, Matt envisions a future where personalized light environments - integrated with sleep and performance data - become central to health optimization. The episode concludes with a shared message: improving light hygiene is one of the highest-leverage, lowest-effort interventions available in modern biohacking.Learn more about Ra Optics at https://raoptics.com and follow Matt on Instagram: @thelightdiet!This conversation was recorded in October 2025.Check https://hololifesummit.com for upcoming events & tickets!
