@DOMESTIC_TERROR @hubermanlab You only get clarity when you isolate variables.
Most “cannabis causes harm” data is mixed with alcohol, poor sleep, drugs, and bad diet.
Without separating the terrain, the conclusion is noise.

how do you separate all the other toxins and activities food, products and factors ? for example they list marijuana as a cause for violence and accidents but always fail to mention they were also drunk and other drugs and never separate the two groups knowing the numbers would be at almost zero with marijuana use only

Cannabis is detrimental to sperm: even if they can fertilize, there can be DNA damage. Many miscarriages and (in the case of IVF) “day 3 crashes” which is when paternal DNA normally kicks in, are cannabis related. Dr Natalie Crawford on the Huberman Lab podcast out now.
English
Anecdotes can be misleading.
Fertility isn’t about “clean vs degenerate” it’s about mitochondrial charge and circadian alignment.
Some people appear fine on the surface, but sperm quality is a very sensitive early marker of deeper redox and environmental stress.
@
@hubermanlab You can cite science all you want but in real life, i have never known a degenerate who drinks and does drugs that have any fertility issues. It’s the good, clean living people who often have trouble conceiving.
English
Embryo halting is usually an energy issue early on mitochondria just can’t keep things going.
Progesterone helps support the environment, but it can’t fix poor starting quality. High sperm DNA damage (DFI) tends to have a bigger early impact than progesterone levels.
heresathought@TimTokarz
@hubermanlab Can someone expand on embryo halting? Any side by side with progesterone production? How do these factor in together ? Would DFI have a greater impact than progesterone?
English
Exactly. Dad’s side matters more than people think.
That Day 3 crash isn’t random it’s an energy issue early on. Fix the environment first, and things start to change.
Lucy ASMR@LucyASMR176908
@hubermanlab This is such a crucial takeaway. We often talk about maternal health, but paternal DNA plays a massive role in those early stages. That 'Day 3 crash' insight is a game-changer for couples struggling with IVF. Thanks for highlighting Dr. Crawford's expertise!
English
You can’t force awareness on people not ready to see.
Fertility struggles are often silent because the environment is uncomfortable to confront. Lead by example light, sleep, habits. When they’re ready, they’ll ask.

@hubermanlab I wish I could send this to some in-laws.. from a place of love.. but they aren’t even open about their infertility struggles so it wouldn’t be received well. (Plus you know how weed smokers are about weed).
English
Anecdote isn’t biology.
You got outcomes but that doesn’t mean the inputs were optimal. Fertility and health are built on light, mitochondria, and environment, not luck.
What works once isn’t always what sustains long term.

English
If they were truly healthy, they wouldn’t need IVF.
Fertility problems mean something’s off light, sleep, toxins. Cannabis can hide it, especially with secrecy.
Steven Nephew@vibeocracy
@hubermanlab If they’re a young healthy couple, then why are they in need of IVF? Could it be Cannabis use, esp if the dudes are being secretive about it, is masking other underlying issues?
English
Exactly. It’s never just the cannabis it’s the environment it drags with it.
Poor light, bad food, no movement, wrecked sleep… that’s what crushes fertility at the mitochondrial level. Fix the light and lifestyle, and the biology follows.
@
@hubermanlab There are MANY unhealthy lifestyle factors that impact sperm and fertility that often come with chronic cannabis use… ultra-processed food, low movement, poor sleep, excess screen time, etc.
English
Careful that feeling is earned, not promised.
Sunrise light is key. Build your solar callus before heavy sun. Skip vitamin D only if your light environment is solid.
Do the basics right for 2 months… and you’ll feel like yourself again, just upgraded.

@AgentChud @Nebraskangooner Sunrise light + tanning, skip vit d supps feel like a god among men in 2 months guaranteed
English
Health doesn’t collapse overnight it fades as your environment slowly mismatches your biology. Light, water, magnetism… when you live out of sync with them, mitochondria lose their charge and the system unravels. Fix the inputs sunrise light, real food and proper sleep
Mongoose Mindset@MongooseMind01
@jackkruses @deeptrance @hubermanlab 100% true! It is not typically one thing that ruins a persons health. It is a combination of bad lifestyle haits that degrade the body and mind over years of maltreatment.
English
You’re right it’s multifactorial.
B vitamin status and insulin resistance both matter, but they sit downstream of mitochondrial and circadian control. Environment sets the biology, food just expresses it.
@
It’s an observational study. It doesn’t mean meat protests from Alzheimer’s but it’s a hypothesis-generating study. My thoughts: - Alzheimer’s is multifactorial, the gene is the gun, the environment the trigger. - two environmental factors in consider 1. Vitamin deficiencies contributing to dementia, even push you over to Alzheimer’s. Meat is replete with high bioavailable b vitamins like B1 and B12. These vitamins are heavily linked to dementia, deficiencies cause irreversible dementia in alcoholics and other people with overt deficient. Other nutrients are likely in play but these two are the most robustly studied. 2. Insulin resistance. We have moderate evidence suggesting that insulin resistance of the brain is a phenomenon. I speculate those eating meat were likely eating more Whole Foods; less refined grains, and perhaps were more metabolically healthy.
English
What matters isn’t “fruit vs leaves,” it’s environmental light, microbial terrain, and food availability shaping gut signaling. Humans are not chimpanzees we’re light adapted primates with different energy demands.
Billy Shakes@BillyShakes15
@hubermanlab @paulsaladinomd @SBakerMD Primates mostly do protein and fruit. They don’t eat leaves.
English
That’s conditioning, not requirement.
Fiber just changes transit mechanics and microbiome signaling. Gut motility is driven more by circadian rhythm, hydration state, and autonomic tone than bulk alone.
English
It’s rarely one variable in biology it’s stacked load over time on the same mitochondrial system.

@ProjectGokuu Only a MAGA would fail to see the reason why NFL players from 70s and 80s, bodybuilders and WWF wrestlers died early was STEROIDS
English
Reducing it to one cause is too simplistic.
Steroids were part of the picture, yes but so were chronic inflammation, repetitive trauma, sleep disruption, cardiometabolic stress, and poor long term recovery environments.

Life is structured resistance to decay through organized energy flow nothing more, nothing less.
@
@QuantumTumbler Very well said. Agency and design in response to the presence of conservation and entropy.
English
Exactly motion is stability.
When energy flow drops, the system must overcorrect to maintain balance. Health is sustained momentum through coherent energy input, not stillness.
@TanyaGabriele@TanyaGabriele
@QuantumTumbler Yes. Just like riding a bicycle. When you lose momentum the necessity to maintain balance by teetering becomes more apparent. ; )))))) ❤️
English
Even in space, direction exists as energy gradients and electromagnetic fields. Gravity just makes it local “up/down.” The universe is never directionless only differently structured flow.
R@Arceneaux828
@QuantumTumbler But falling represents direction I get we on the ground and the analogy of standing up and catching yourself but what about space what created direction in the first place outside the gravity of earth somthing with no known center or origin you can't fall or rise from it
English
Exactly biology is never static.
What you’re describing is homeodynamics, not equilibrium. Continuous feedback between gravity, vestibular input, and mitochondrial redox keeps the system alive and adaptive. Stillness is an illusion; controlled fluctuation is health.
@
Exactly, balance does not mean staying perfectly still. In reality, true balance involves constant, subtle adjustments rather than stillness. Even when we stand upright still, our body experiences small postural sway—tiny horizontal adjustments in our center of gravity, so balance requires active control, not passive stillness.
English
The “cooperation” happens through redox, quantum biology, and circadian light inputs that tune cellular signaling. When those inputs are right, coherence emerges across all layers automatically no force needed.
Bianca Bell-Chambers@BiancaBellChamb
Exactly. It’s always about balancing your own equilibrium. We are in constant motion – body, thoughts, feelings… everything is continuously adjusting inside a highly complex system. If we don’t limit ourselves to our personal conscious mind but also cooperate with the other levels of consciousness – like the cells that form our body – then it becomes a true cooperation of consciousnesses. Together they keep the waking mind, the subconscious, the cellular awareness and the body awareness in harmony. That way the entire complex system keeps striving to maintain its own equilibrium and health.
