For decades, aging was framed as a problem of damage.
Oxidative stress.
Cellular breakdown.
Molecular decline.
But new perspectives are emerging.
@MitoPsychoBio and colleagues propose something deeper:
Aging may also be an energy conservation problem.
As cells accumulate stress and become metabolically inefficient, they send signals of energetic distress.
The brain detects those signals and gradually shifts the organism into energy-saving mode.
Less vigor.
Less repair.
Less plasticity.
Less resilience.
Not because life suddenly “breaks”.
But because the system is trying to survive within a shrinking energy budget.
This perspective reframes longevity.
The goal may not simply be to suppress damage.
It may be to restore bioenergetic efficiency.
Mitochondria.
Metabolism.
Inflammation.
Energy signaling.
Life runs on energy.
And longevity may depend on how efficiently we produce it, allocate it, and preserve it.
The most powerful antioxidant in your body ?
It’s not vitamin C. It’s melatonin.
Melatonin isn’t just a sleep hormone.
Sleep may actually be one of its least interesting functions.
Melatonin has been viewed primarily as a hormone released by the pineal gland at night.
A sleep signal.
A biological clock.
A darkness messenger.
But emerging biology suggests something much deeper.
Melatonin is one of the most powerful antioxidants known in nature.
A single melatonin molecule can neutralize up to 10 reactive oxygen and nitrogen species through a unique antioxidant cascade.
Vitamin C can’t do that.
Vitamin E can’t do that.
Melatonin is different.
The protection continues.
Unlike many antioxidants, melatonin does not become pro-oxidant after donating electrons.
It keeps going.
But that’s only part of the story.
Melatonin also:
increases glutathione synthesis
upregulates superoxide dismutase
activates catalase
supports glutathione peroxidase
protects mitochondrial membranes
reduces lipid peroxidation
modulates inflammation
supports immune surveillance
Melatonin is not primarily a sleep molecule.
Sleep is simply when one of its most important jobs takes place.
Repair.
Protection.
Maintenance.
Melatonin is found in the pineal gland, in the brain, throughout the body.
And potentially..
within mitochondria themselves.
Almost as if biology evolved a way to place one of its most powerful protective systems exactly where energy production occurs.
Which raises an uncomfortable question.
If melatonin is one of the body’s most important protective molecules…
What happen when modern humans suppressing it every night?
Screens.
Artificial light.
Lack of darkness.
Late-night exposure.
Disrupted circadian rhythms.
For most of human history, the body received two ancient instructions every day:
Light meant activity.
Darkness meant repair.
Today, we have blurred both signals.
Too little natural light during the day.
Too much artificial light at night.
And biology may be paying the price.
Melatonin was never just about sleep.
It may be one of the molecules through which darkness becomes repair.
So maybe the real question is not:
How much sleep are we getting?
But are we still giving our biology signals it was built to understand?
@NoahRyanCo Yes and yes.
Dealing with a blastocystis parasite right now.
Third-country visit yes, but awareness about exposition to them through water, restaurants etc
Continuous detox diet, incorporate garlic, cloves, papaya seed etc on a regular basis
+ a protocol to detox in case.
You don’t have a focus problem.
Your nervous system is overloaded.
If you can’t focus, stop asking:
“Why am I so lazy?”
Ask:
“What state is my brain in?”
Focus is not a personality trait.
It is a biological state.
Here’s the protocol:
1. Fix light first
Morning sunlight within 60 minutes of waking.
No sunglasses.
No phone first.
Your brain needs a time signal before it needs dopamine.
2. Remove the dopamine flood
For the first 60 minutes:
No X.
No email.
No notifications.
No short videos.
If your brain starts the day reactive, deep work becomes harder.
3. Do one slow physiological reset
2 inhales through the nose.
Long exhale through the mouth.
Repeat 3–5 times.
This tells your nervous system:
“You are safe enough to think.”
4. Move before you work
10–20 minutes walking.
No podcast.
No scrolling.
Movement increases arousal without overstimulation.
That is the state you want.
5. Work in one clean block
90 minutes.
One task.
Phone away.
No tabs.
No music with lyrics.
No context switching.
Your brain cannot enter focus while defending against 12 inputs.
6. Eat for stable cognition
Don’t start deep work while underfed, over-caffeinated or crashing.
Stable blood glucose = stable attention.
7. Recover like focus depends on it
Because it does.
Poor sleep lowers executive function.
Stress lowers cognitive control.
Overload makes cheap dopamine more attractive.
You are not distracted because you are weak.
You are distracted because your brain is adapting to an environment designed to fragment it.
Fix the state.
Then focus follows.
@NoahRyanCo I think Deuterium isn’t a problem until you drink liters of coconut water and tons of mangoes and ananas while in the depth of a UK winter, while you should do it in on a freaking tropical beach full of dogs and under UV9
Reducing sunlight to vit D is like reducing food to being full.
You’re missing most of the story.
Too much sunlight can be harmful.
But not enough may be worse.
We have underestimated what sunlight actually is.
For decades, sunlight has largely been viewed through two lenses:
Vitamin D.
Or skin damage.
But emerging mitochondrial biology suggests something much deeper.
Sunlight is not simply something we see.
It is biological information interacting with cellular energy systems.
Red and near-infrared wavelengths, abundant in natural sunlight, can penetrate tissues and reach mitochondrial chromophores, including cytochrome c oxidase.
When absorbed, these photons can influence:
• electron transport
• mitochondrial membrane potential
• nitric oxide signaling
• ATP production
• blood flow
• inflammation
• cellular repair pathways
The deeper we study mitochondria, the less they resemble simple powerhouses.
They increasingly appear as dynamic environmental sensors continuously responding to:
• light
• temperature
• circadian timing
• movement
• stress
• metabolic state
Even cellular water may play a more active role than previously believed through charge separation, proton dynamics and intracellular organization.
This changes how we think about health and longevity.
Food provides molecular substrates.
Sleep restores biological capacity.
Movement builds adaptation.
But light may be one of the most fundamental biological signals life evolved with.
The body is not isolated from its environment.
It continuously senses, translates and responds to it.
Perhaps the question is no longer whether sunlight affects biology.
But how much modern humans have become disconnected from it.
@VanceE Photobiomodulation also has a systemic effect.
Using it on most important regions like the brain or gut - and with the right device - have effects through all your body and organs at once.
How to improve your hormonal health, clean your body toxins (and become a little bird-like-metabolic-little-peater)
STEP 1 :
Raw carrot salad is one of the simplest metabolic tools most people ignore.
Ray Peat popularized it because the raw carrot acts almost like a natural intestinal brush.
Its insoluble fibers move through the gut without being heavily fermented, binding bacterial waste, excess bile acids and compounds that would otherwise recirculate back into the bloodstream.
This matters because the gut is one of the biggest regulators of your hormones, inflammation and energy.
When digestion slows down, endotoxin increases.
Endotoxin irritates the intestine, burdens the liver, raises inflammatory signals, increases serotonin, increases cortisol and pushes the body into a more stressed metabolic state.
A daily raw carrot salad helps clean that terrain.
The mechanism is simple:
raw carrot fiber + vinegar + salt + coconut oil / olive oil
The fiber scrubs.
The vinegar supports acidity.
The salt supports minerals and digestion.
The coconut oil adds antimicrobial saturated fats.
The olive oil helps bile flow.
Together, they create a simple gut-liver-hormone support tool.
This is why the carrot salad is often used to support:
• lower endotoxin burden
• better bowel regularity
• improved estrogen clearance
• better liver detox capacity
• lower serotonin load from the gut
• reduced bloating
• cleaner digestion
• more stable mood
• better metabolic rate
• better hormonal balance
If the liver and intestine are congested, estrogen gets reabsorbed instead of eliminated.
This is the part most people miss.
Hormonal health is about testosterone, progesterone, thyroid hormone…
Yes..
It starts by clearing the metabolic waste that blocks the system.
The gut decides how much inflammation enters the blood.
The liver decides how well hormones are processed.
The intestine decides whether estrogen leaves the body or comes back in.
The raw carrot salad supports this whole axis.
Simple protocol:
Grate 1 raw carrot.
Add coconut oil or olive oil.
Add vinegar.
Add sea salt.
Eat between meals or before lunch.
Do it daily for 7–14 days and observe:
digestion
skin
bloating
mood
bowel movements
temperature
libido
clarity
stress response
Sometimes the most powerful metabolic interventions are not exotic.
They are simple foods used with the right biological logic.
The carrot salad is.. a salad.
And a gut-liver-hormone hygiene ritual.
