Biohacking
Everything on stimulus and recovery: sauna, cold, light and what the studies actually show — explained simply, with sources.
Sauna & heart health: what the Finnish studies show
Regular sauna use is more than relaxation: large long-term studies from Finland link it to a healthier heart and a higher life expectancy. What lies behind it.
Cold therapy & ice bath: hype or real benefit?
Ice baths have become a longevity trend. What cold water triggers in the body, what research has proved so far – and how you start safely without overdoing it.
NMN & NAD⁺: a reality check on longevity supplementation
NMN is celebrated as a big promise in the longevity scene. What lies behind the NAD⁺ molecule, what is actually proven in humans so far – and why caution is warranted when it comes to its legal status.
Red light & infrared: what light therapy can really do
Red-light panels promise better skin, faster recovery and more energy. What lies behind Photobiomodulation, what is backed by evidence – and where the hype outpaces the data.
Altitude training: how thin air makes your body stronger
Elite athletes swear by training at altitude. How the lack of oxygen forces the body to adapt, what it delivers – and how the effect becomes accessible to ambitious non-professionals too.
Alcohol & longevity: what current research shows about regular consumption
For decades, a glass of red wine in the evening was considered good for the heart. Newer studies challenge this myth. What current research really knows about alcohol and health — and why the question is more complex than it seems.
Berberine: The plant-based molecule with blood-sugar-lowering effects examined
In the biohacking community, berberine is often called a plant-based metformin — and research does show some noteworthy effects on blood sugar. What holds up, and where does the evidence end?
Blue Light & Melatonin: How screens affect your sleep hormone
Almost everyone checks their smartphone or laptop in the evening — but what does that light do to your sleep hormone? How blue light suppresses melatonin production and what you can do about it.
Continuous glucose monitoring: What a CGM sensor reveals about your metabolism
Continuous Glucose Monitors, or CGMs, were originally developed for people with diabetes — but biohackers use them to see in real time how their body responds to meals, exercise, and sleep. What they show and what their limits are.
CO₂ tolerance: why breathing training does more than just relax you
Most breathing exercises are associated with relaxation and stress relief. But there is a second, less well-known effect: CO₂ tolerance. What this concept is about and why it can influence your performance and resting breathing.
Exogenous ketones: performance booster or expensive trend?
Ketones as a supplement promise more energy, sharper thinking, and faster ketosis without giving up carbohydrates. What research shows — and why the reality is more nuanced than the product claims.
Grounding & Earthing: What Research Shows About Earth Contact
Barefoot on the lawn, earthing mats in bed — grounding promises to reduce inflammation and improve sleep. What's behind it, and what do the available studies actually say?
Hormesis: Why a little stress makes your body stronger
What sauna, cold immersion, fasting, and intense exercise have in common: they are all controlled stress stimuli that the body responds to by adapting. The principle behind this is called hormesis — and it explains why biohacking brings together so many seemingly contradictory methods.
Testosterone & co. — naturally optimising hormones: what the research shows
Testosterone, oestrogen, cortisol — hormones control energy, muscle mass, mood, and sleep. Beyond hormone therapy, there are lifestyle levers with real effect. Here is what the research says.
Caffeine timing: When you should drink coffee — and when you shouldn't
Drinking your first coffee right after waking up is a widespread habit — but possibly not the optimal one. What chronobiology says about caffeine, cortisol, and adenosine.
Optimizing Mitochondria: What Research Says About More Cellular Energy
Mitochondria supply almost every cell in your body with energy. Their efficiency declines with age — but certain stimuli promote their renewal. What actually helps and where the limits of the research lie.
Morning light: How early light exposure sets your biological clock
Anyone who checks their screen first thing in the morning is missing out on a free, powerful biohacking tool: direct daylight. How early light exposure anchors your circadian rhythm — and why it does more than any sleep supplement.
Peptides in biohacking: What BPC-157 and Thymosin show in studies
Peptides like BPC-157 and TB-500 circulate in biohacking circles as quick regeneration aids for joints and muscles. But most studies were conducted in animals — what is transferable to humans remains scientifically uncertain.
Spermidine: The Autophagy Molecule in Foods and as a Supplement
Spermidine is found in wheat germ, cheese, and mushrooms and is considered one of the most promising natural autophagy activators. What the research shows — and what remains open.
Urolithin A: The molecule from pomegranates and its effect on mitochondria
Urolithin A is produced when certain gut bacteria break down polyphenols from pomegranates and walnuts. In human studies it showed effects on mitochondrial health — making this molecule one of the most interesting newer longevity candidates.
