Not caffeine or another productivity app — I’m curious about things that noticeably changed your focus or cognitive performance.
Nutrition, breathwork, light, supplements, exercise, anything.
What made the biggest difference for you?
Travel seems to destroy routines faster than anything else — sleep, meals, training, hydration.
I’ve started keeping just 2–3 habits consistent instead of trying to maintain everything.
What’s the one thing you never drop, even when you’re traveling?
They didn’t disappear—they fused together.
At birth, your skeleton is made up of around 270 separate bones. Many of them are still made of flexible cartilage, allowing your body to grow and making birth possible.
As you develop, these smaller bones gradually join together. By adulthood, you’re left with 206 stronger, more stable bones that better support movement, protect your organs, and handle everyday stress.
And the story doesn’t end there.
Your skeleton is living tissue. Throughout your life, your bones are constantly breaking down and rebuilding themselves—a process called bone remodeling. Every walk, workout, and nutrient you give your body helps shape the strength of your skeleton.
🦴 Your body isn’t just built once. It’s designed to adapt for a lifetime.
💬 What’s the most surprising fact you’ve learned about the human body?
Two groups were given the exact same task.
One group was told they’d be “isolated.”
The other was told they’d have “me time.”
Same situation. Completely different framing.
The “me time” group showed significantly more positivity and emotional self-belief.
It’s an interesting example of something Case Kenny calls the “language of optimism” — the idea that the words we use to describe our experiences can influence how we actually experience them.
Case has spent the last decade exploring this through his podcast New Mindset, Who Dis?, his writing, and talks for organizations including the NFL, Meta, Nike, and universities across the U.S.
He’ll be joining us at Biohackers World Chicago to bring the Language of Optimism to the stage.
Curious what this community thinks: Is reframing actually a form of mental biohacking, or are we stretching the definition of “biohacking” too far?
A recent study from researchers at the University of Otago found that eating 2 kiwifruit daily for 8 weeks increased vitamin C levels not only in the blood, but also in the skin — alongside improvements in markers related to skin structure and renewal.
Obviously, kiwi isn’t going to replace your entire skincare routine. But it raises an interesting point about how much we focus on what we put on our skin versus what we give our body from within.
For the biohackers here: have you noticed any real changes in your skin from changing your diet or increasing vitamin C-rich foods?
Here are 9 that actually do what people claim (and how to use them right):
🟠 Turmeric — anti-inflammatory, but only works well paired with black pepper (piperine boosts absorption ~2000%)
🟤 Ashwagandha — clinically shown to lower cortisol, best taken in the evening
🟡 Ginger — eases nausea & supports digestion, take with meals
🟢 Peppermint — reduces IBS symptoms, most effective as tea or enteric-coated capsule
🩷 Rhodiola — reduces fatigue & improves stress resilience, take in the morning
🟣 Milk Thistle — supports liver detox pathways, take with food
⚪️ Chamomile — improves sleep quality, best in the evening
🟨 Ginseng — boosts energy & cognitive focus, morning use
⬜️ Garlic — supports cardiovascular health, take with meals
Timing and pairing matter as much as the herb itself. Save this so you’re not wasting what you’re already taking. 📌

From biological age testing and vagus nerve stimulation to neurofeedback and women’s health innovations, the next generation of health technology is focused on understanding your body like never before.
While some of these tools are still emerging and research is ongoing, they highlight where personalized health is heading.
Technology won’t replace the fundamentals—but it can help you make more informed decisions about your health.
Which innovation are you most excited to see become mainstream? 👇
Imagine having 2 full days to explore some of the latest biohacking and longevity technologies in person — testing devices, meeting the people behind them, and hearing directly from experts and speakers in the space.
No endless scrolling. No trying to figure out what's legit from a 30-second Reel. You actually get to see it, ask questions, and experience it yourself.
Would you go?
And what would make it worth it for you — the tech, the speakers, networking, or getting hands-on with devices?
Curious what fellow biohackers would want to see at an event like this.
Been noticing three camps forming in dairy discussions lately and curious what people here have actually experienced:
Team Raw Milk — swears by it for gut health, claims pasteurization kills beneficial enzymes/bacteria and denatures proteins. Some report better digestion and skin than with pasteurized milk.
Team Lactose-Free — still want dairy's benefits (protein, calcium, satiety) but cut lactose specifically, either via lactase supplements or lactose-free products.
Team No Dairy — avoid it entirely, whether for inflammation concerns, casein sensitivity, or just don't think mammal milk makes sense for adult humans.
Genuinely curious:
Research from multiple populations worldwide has found links between nutrition quality, animal protein intake, and height development during childhood and adolescence.
Historical data from countries like Japan and the Netherlands showed major increases in average height alongside improvements in nutrition, healthcare, and overall living conditions.
Animal foods provide complete protein plus key nutrients like iron, zinc, calcium, and vitamin B12 that help support growth, development, hormones, and bone health.
Genetics still plays the biggest role in height, but nutrition, sleep, physical health, and environment also influence whether someone reaches their full growth potential.
We’ve been told: high cholesterol = danger.
But it’s more nuanced.
Studies show both very low and very high cholesterol
can be linked to higher risk.
Because cholesterol isn’t the problem — it’s a signal.
Low levels can reflect:
• undernutrition
• inflammation
• liver or thyroid issues
High levels are often driven by:
• insulin resistance
• high sugar / refined carbs
• poor metabolic health
What actually matters:
- ApoB (particle number)
• inflammation
• metabolic health
Also: eating cholesterol (like eggs)
doesn’t automatically raise blood levels.
The goal isn’t to chase a number — it’s to understand what’s driving it.
Gratitude is one of the most studied interventions in neuroscience — and one of the most underestimated tools in biohacking.
fMRI scans show that genuine gratitude activates the brain’s reward center and prefrontal cortex — the same regions responsible for emotional regulation, decision-making, and resilience. It triggers dopamine, serotonin, and oxytocin while dropping cortisol by up to 23%.
And the structural changes last. Participants in one Indiana University study showed measurable differences in brain activity months after a 3-week gratitude practice ended.
This isn’t soft science. It’s neuroplasticity in action.
Key studies referenced: → Glenn Fox et al., USC — fMRI gratitude neuroimaging, 2015 → Prathik Kini et al., Indiana University — NeuroImage, 2016 → Robert Emmons, UC Davis — cortisol + wellbeing, longitudinal study → Alex Korb, UCLA — serotonin and the search for gratitude → Narrative review, PubMed/PsycINFO 2000–2024 — neuroplasticity and gratitude interventions
Every time peptides get mentioned online, someone immediately jumps in with “they’re not FDA approved.”
Okay… but neither are a lot of things people take daily without thinking twice. Creatine. Fish oil. Melatonin. Most supplements in general.
Meanwhile, ultra-processed food, alcohol, cigarettes, and artificial dyes are completely normalized and legally sold everywhere.
I’m not saying people should blindly inject random stuff they bought off the internet. Obviously sourcing, quality, provider, dosing, and actual research matter.
But “FDA approved” has turned into this catchphrase people repeat without understanding what it actually means.
There’s a huge difference between:
Feels like the conversation online has become more emotional than informed lately.
Chronic stress activates NF-κB — a molecule that switches ON
pro-inflammatory genes linked to disease, accelerated aging,
and burnout.
The science is clear: your nervous system state is not just
a feeling. It’s biological data your DNA is reading 24/7.
The good news? Research shows this process is reversible.
Mindfulness, breathwork, cold exposure, and regulated sleep
have all been shown in peer-reviewed studies to downregulate
inflammatory gene pathways.
Key studies referenced in this post:

What’s one thing that noticeably lowers your stress levels and helps your body feel regulated again?
Curious what’s actually working for people beyond the trends 👇
Lately my entire feed is people taping their mouths, wearing blue light glasses at 7pm, magnesium before bed, cold rooms, sleep trackers, blackout curtains, no caffeine after 10am, sunrise alarms… all just to optimize sleep scores 😂
What’s funny is that out of all the biohacking trends, sleep is probably the one thing that actually changes how I feel the next day immediately. Mood, focus, cravings, anxiety, gym performance — everything is different after one bad night.
At the same time, I wonder if some people are taking it too far and stressing themselves out trying to get “perfect” sleep metrics every night.
Curious where everyone stands on this:
What actually improved your sleep the most?Any sleep hacks that turned out to be overrated?Are wearables helping or just creating sleep anxiety at this point?
Unlike repetitive exercise, dancing activates multiple brain areas at once (movement, memory, coordination, decision-making).
Research suggests:
Running trains endurance.
Dancing trains body + brain.
Simple idea:
2–3x/week, even 10–30 min, try a new style or just freestyle.
Curious — do you see dancing as a real “brain biohack” or just movement?
Anyone here actually using it intentionally?
When muscles contract during exercise, they release molecules called myokines that help communicate with the brain and body.
Research links regular movement to:
• Better mood
• Reduced inflammation
• Improved brain function
• Support for neuroplasticity
• Lower symptoms of mild depression
This is why exercise is more than fitness—it’s biological medicine.
You don’t need a perfect workout to benefit:
• 10-minute walk
• Bodyweight exercises
• Strength training
• Any consistent movement
Sometimes the most effective tools aren’t external—they’re already built into the body.
What kind of movement helps you feel your best?
