Could Feeling Better Be Different Than Getting Better?

Habituation is the process of gradually reducing the brain's response to something through repeated exposure.

Think about moving into a home next to train tracks.

During the first few nights, every train may wake you up. The sound feels loud, disruptive, and impossible to ignore.

After living there for several months, you may barely notice it.

The trains did not stop passing by. Your brain learned that the sound was predictable and did not require the same level of attention.

That is habituation.

In the right situation, habituation can be useful. It can help the brain become less reactive to movement, visual motion, sounds, sensations, or environments that have become unnecessarily threatening or uncomfortable.

But it raises an important question:

Are we helping the brain respond less, or are we changing the reason it was responding in the first place?

Habituation is an important and evidence-supported part of many rehabilitation programs.

For someone whose nervous system has become overly sensitive to movement or visual input, gradual exposure may help reduce symptoms and restore confidence.

The goal of this article is not to argue that habituation is wrong.

The question is whether habituation is the complete answer for every person.

If repeated exposure reduces symptoms, that is meaningful. Feeling better matters.

But symptom reduction alone does not always tell us what changed.

Several of those changes may happen at the same time. Without reassessment, it can be difficult to know which one occurred.

When someone reports fewer symptoms, that improvement is real.

But there are several possible explanations for why they feel better.

None of these possibilities should be dismissed.

The important question is whether the system is becoming more efficient, or whether it is simply finding a way to keep the symptoms under control.

Compensation is one of the brain's most useful abilities.

If one source of information is unreliable, the brain may rely more heavily on another.

Someone with vestibular dysfunction may depend more on vision. They may move more slowly, tighten their body, avoid quick head movements, or use increased concentration to maintain balance.

These strategies may allow them to feel much better during a normal day.

But compensation often requires resources.

When the person is rested, healthy, and in a predictable environment, the strategy may work well.

Then another demand is added.

The brain now has to manage the original problem and the additional stressor at the same time.

That may be when symptoms become visible again.

The stressful event did not necessarily recreate the original dysfunction. It may have challenged the strategy the brain was using to keep it under control.

This is the question I do not want rehabilitation to skip.

Instead of asking only, "How do we reduce the symptom?" I also want to ask:

That does not mean every symptom has one hidden root cause.

Persistent symptoms are often influenced by several systems at once.

But if we stop investigating as soon as the symptoms decrease, we may miss an opportunity to understand why the symptoms were present in the first place.

Symptoms are important, but symptoms do not always tell the whole story.

Someone may feel less dizzy while their balance remains unstable.

Someone may tolerate a grocery store better while their visual motion processing has not meaningfully changed.

Someone may report improvement because they have become skilled at avoiding the movements that previously triggered symptoms.

Those experiences still matter, but I want to understand what changed.

That is why I rely heavily on objective reassessment.

Depending on the person, that may include repeating measurements of:

If the measurements improve along with the symptoms, that gives us evidence that the function itself may be changing.

If the person feels better but the measurements remain unchanged, that does not mean the improvement is unimportant.

It means we should ask whether habituation, compensation, avoidance, or another factor may also be contributing.

I do not want to assume an exercise worked simply because time passed.

I want to measure what changed.

This does not have to be an either-or discussion.

A person may benefit from habituation while also working on vestibular function, eye movements, balance, strength, autonomic regulation, sleep, or another contributing system.

Gradual exposure may help the brain stop treating safe movement as a threat.

At the same time, targeted rehabilitation may help improve how the brain processes and responds to that movement.

The right combination depends on the person.

For some people, habituation may be a major part of recovery.

For others, it may reduce symptoms without fully addressing the dysfunction contributing to them.

For many people, several approaches may be needed together.

When symptoms return, it can feel as though everything you accomplished has disappeared.

That is not always true.

A flare may reflect temporary overload rather than a complete loss of progress.

It may show that the system has improved but is still relying on more compensation than we realized.

It may reveal a specific function that still becomes vulnerable under stress.

It may also be an entirely new issue that deserves evaluation.

The pattern matters.

Symptom reduction matters.

Everyone wants to feel better.

There is nothing wrong with helping the brain become less reactive to safe movement or sensory input.

But I do not want the investigation to end there.

If an underlying system is not functioning efficiently, there may be an opportunity to address it more directly.

The fastest way to the finish line is not always teaching the brain to tolerate the problem better.

Sometimes it is identifying what is creating the problem and helping that system function more efficiently.

Sometimes feeling better is exactly what recovery looks like.

Other times, it may be one step along the way.

The goal is not simply to reduce the alarm.

The goal is to understand why the alarm was activated and determine whether anything can be changed.
