Ever walked into a nursing home and noticed that smell?

We all recognize it:
Musty. Greasy. Stale.

Almost like old books mixed with something sour.
Eeew!

Scientists have actually identified the “old people smell” compound.
They call it 2-nonenal.

Not exactly dinner conversation.

But understanding it may help us age better.

And no, this isn’t simply about poor hygiene.

Even very clean people can develop it.

The good news?

​Your body chemistry can change - for the better.

As we age, it seems everything changes. Including the oils in our skin and body.

One researcher described it this way: the fats in our body slowly oxidize as we get older. In other words, they begin to go a little rancid. Then, we literally off-gas the smell.

Not the prettiest image.

That familiar “nursing home smell” isn’t usually caused by someone forgetting to shower. It’s tied to oxidative stress and changes in skin chemistry that happen over time.

This process tends to increase after age 40.
Forty! That's not even old.

Here's another kicker: since nonenal clings to fabrics, bedding, furniture, and clothing more than normal sweat odors do, it lingers throughout entire nursing homes.

And, wouldn't you know? The person giving off the odor can’t even smell it themselves.
​Because we become accustomed to our own scent.

​So, I am not afraid of asking, "How do I smell?"

For years, I thought body odor was simply something I had to manage.

That was when I was younger, and used to stink.

Not just after exercise.

All the time.

I often applied deodorant multiple times a day.

Then I slowly cleaned up my diet. Lifestyle, too. (See my other articles to find out more.)

Gradually, the odor faded.

Today, I rarely need deodorant at all.

Now I realize: I don’t actually want to silence those smelly signals completely.

Because odors are the body's feedback. 

What you eat, and what you lather on your body, becomes part of your chemistry.

And today's life creates enormous stress on the body:

From lead-ridden lipsticks and synthetic fragrances, to toxic cleaning products and dental floss laden with forever chemicals.

Maybe the problem isn’t age alone.
Maybe it’s that modern life is cooking us from the inside out.

The bottom line is that the body communicates our imbalance through odors.

Dogs are super sniffers. They can even detect certain diseases simply by scent:
 Parkinson’s disease, diabetes, kidney disease, liver dysfunction, infections, and more.

Imagine learning you have Parkinson's disease just by how you smell!

​So, maybe we can "listen" better to our smells.

Sweat. That's the smelly culprit, right?

Sort of. But, your microbiome plays a major role, too.

Your skin contains billions of bacteria, many of which are protective and beneficial.

One microbiologist became so fascinated with healthy bacteria that he stopped washing for years while researching the microbiome.

His observations?

Cleaning with soap scrubs away our healthy microbiome.
Animals, on the other hand, will "wash" by rolling on the ground.
That replenishes healthy bacteria.

Recent studies also show that children who play on natural earth playgrounds develop more resilient immune systems than children exposed only to "safe" rubber play surfaces.

Now, I’m definitely not suggesting people stop bathing.

But I do have the following question:

Modern culture treats every natural smell as unacceptable.

So we spray.
Plug in. 
Perfume.
Deodorize.
Antibacterial everything.

But sweat and smell are not the enemy.

Your skin and breath are two of the body’s detoxification pathways.
(Pee and poop are others.) 
The body continually tries to eliminate waste and maintain balance.

Sweating matters. The lymphatic system matters. The microbiome matters, too.

Nobody wants to smell bad.

But masking or completely suppressing the body’s natural processes?
Not the best long-term strategy.

​Because the very products designed to “help” us may actually interfere with the body’s own feedback loop.

So, I changed the way I approach odors.

I stopped trying to overpower smells and started paying attention to them instead.

I cleaned up my food.

Read labels.
Found the word "fragrance" hiding hundreds of undisclosed chemical compounds.

Switched to simpler, natural products.

Exfoliated.

Sweated.

Walked barefoot on the ground.

Breathed in beautiful smells.

Reduced the toxic burden before even coming into contact with it.

...And gradually, my body changed.

This may be one of the biggest factors in aging odor.

I want to keep those rancid, oxidized fats from making me smell like a nursing home. 

So, I've researched super antioxidants.

No. Not for me. 

My goal is to age better. Healthier.

Because healthy people smell better, naturally.

​And more importantly, they tend to have:

That’s what I care about.

Taking control of how we age.

And paying attention to our smells -- the body’s early warning sign.

I no longer think body odor is simply something I have to manage forever.

Turns out, my smelly body was just asking for help.

Once I started paying attention to those stinky signals, reducing toxic load, improving my diet, supporting detoxification, and managing oxidative stress, my chemistry changed.

That’s become my entire philosophy on longevity.

Support the body. Don't fight it.

After all, it's just trying to heal, naturally.
