What the World Doesn’t See About Sickle Cell

Every year on World Sickle Cell Day, we talk about awareness.

Awareness of pain.

Awareness of disparities.

Awareness of the need for better treatments and access to care.

And those conversations matter deeply.

But after years of working in hematology, sitting beside patients during pain crises, hospitalizations, transfusions, fear, frustration, resilience, and survival… I’ve realized there’s another conversation we’re still not having enough:

What chronic stress does to a body already fighting to carry oxygen.

I often explain it this way: Imagine driving a car with the emergency brake partially on all day, every day.

You can still move forward.

You can still function.

You may even become incredibly high-performing.

But over time, the system pays for it.

That’s what I see so often in sickle cell.

The body compensates beautifully… until it can’t.

And yet, many individuals living with sickle cell become experts at overriding their own signals because they’ve had to. They have become experts at functioning while uncomfortable.

They push through exhaustion.

Minimize pain.

Ignore stress.

Downplay symptoms.

Delay rest.

Continue functioning while their nervous system and physiology are screaming for support.

Not because they want to.

Because they’ve had to.

And after years of this, survival stops feeling like an emergency and starts feeling normal.

Because over time, the nervous system adapts to living in a constant state of anticipation.

Anticipation of pain.

Of dehydration.

Of weather changes.

Of stress.

Of being misunderstood.

Of waiting too long to seek care.

Of seeking care and not being believed.

Imagine spending years in a body where your internal alarm system never fully powers down.

This condition is not just painful.

It’s physiologically exhausting.

And yet, I continue to be amazed by the resilience of this community.

I’ve watched patients laugh while in pain.

Show up to work after sleepless nights.

Care for families while silently carrying enormous physical burden.

Advocate for themselves in systems that often require them to “prove” their pain.

People living with sickle cell are often carrying far more than anyone realizes.

As providers, we often focus on the visible crisis.

The vaso-occlusive episode.

The acute chest syndrome.

The hospitalization.

The labs.

But there’s another layer happening underneath it all: the cumulative physiologic burden of unpredictability, hypervigilance, inflammation, pain anticipation, medical trauma, sleep disruption, and chronic stress.

As a hematology nurse practitioner, one of the biggest shifts in my own understanding came when I stopped viewing stress as something separate from sickle cell.

Because stress changes physiology.

Stress changes blood flow.

Stress amplifies pain signaling.

Stress increases inflammation.

Stress alters oxygen demand.

Stress shifts the nervous system into protection and survival.

And when the body spends years in that state, it can begin to lose its baseline sense of safety.

That does not mean symptoms are “just anxiety.”

It means the nervous system has adapted to unpredictability.

The body becomes vigilant.

Protective.

Braced.

Not weak.

Not dramatic.

Rather, the body adapts around protection.

This is why healing has to become bigger than simply reacting once a crisis begins.

Of course medical treatment matters.

Hydration matters.

Disease-modifying therapies matter.

Pain management matters.

But so does helping the body experience moments of safety again.

Moments where the nervous system is not preparing for impact.

Because healing is not only about what we do during a crisis. It's also about what we practice between them.

The small moments matter more than people realize.

One breath.

One pause.

One moment of unclenching the jaw.

One reminder that the body does not have to stay in survival mode every second of the day.

Not perfection.

Not toxic positivity.

Not pretending things are easy.

Just creating small physiologic moments where the system can soften.

Pumping the breaks (consistently) on the stress response.

That’s where change begins.

A Simple Practice to Help Retrain the Nervous System

This practice is not meant to “fix” sickle cell.

It’s meant to help the body experience a different internal state, even briefly.

And over time, those moments matter.

Try this:

Place one hand on your chest and one hand on your stomach.

Take a slow inhale through your nose.

Then exhale slowly with a soft hum.

Not forced.

Not perfect.

Just gentle vibration.

As you exhale, allow your shoulders to drop slightly.

Now ask yourself: What feels supportive in this moment?

Not tomorrow. Not next week. Just right now.

Maybe it’s water.

Rest.

Stepping outside.

Texting someone safe.

Taking another breath.

Repeat this for 3 slow breaths.

That hum, that breath, that touch —they’re not random.

They help stimulate the vagus nerve, shift autonomic state, and reconnect the brain with the body in a safer way.

Tiny signals of safety. And healing often begins with signals.

This World Sickle Cell Day, I’m thinking about every patient who has had to become resilient far too early.

Every person who learned to keep going while silently carrying enormous physiologic and emotional weight.

Every family navigating uncertainty while trying to maintain normalcy.

You deserve care that sees the full picture.

Not just your labs.

Not just your pain score.

Not just your diagnosis.

But your nervous system.

Your lived experience.

Your humanity.

And I truly believe the future of sickle cell care will come not only from better therapies—but from a more integrated understanding of the body itself.

One where blood, stress, pain, physiology, and healing are no longer treated as separate conversations.

Because they never were.
