Borrowed Relief: How Substances Can Undermine Mental Stability

There is often a misunderstanding about why people use substances.

It is rarely about recklessness.

It is often about regulation.

Many high-performing adults who appear composed externally are living with chronically activated or chronically depleted nervous systems. When the body does not know how to settle itself, or does not feel safe enough to, substances can become a fast, reliable intervention.

Alcohol to soften hyperarousal.

Cannabis to quiet intrusive thoughts.

Nicotine to focus.

Stimulants to mobilize.

Sedatives to sleep.

From a neurobiological standpoint, this makes sense.

Substances as Nervous System Tools

Research in affect regulation and trauma psychology suggests that substance use frequently functions as an attempt at self-regulation rather than sensation-seeking behavior. When the autonomic nervous system is dysregulated, cycling between sympathetic overactivation (fight/flight) and dorsal shutdown (freeze), the body searches for relief.

Substances can temporarily:

• Decrease amygdala activation

• Increase dopamine or GABA signaling

• Blunt cortisol response

• Provide rapid shifts in state

  
  

The relief is real.

But it is often short-lived.

The Problem: Borrowed Regulation Comes With Interest

While substances may initially soothe, clinical literature indicates that repeated external regulation can reduce endogenous regulatory capacity over time.

In practical terms:

• Sleep architecture becomes disrupted

• Anxiety rebounds

• Mood destabilizes

• Motivation declines

• Baseline stress tolerance decreases

  
  

Over time, what began as relief can amplify underlying depression, anxiety, trauma symptoms, or attention difficulties.

This is especially relevant for professionals under chronic performance pressure. When productivity must continue regardless of internal state, substances can quietly become part of the coping infrastructure.

When Somatic Regulation Is Underdeveloped

Many adults were never taught how to regulate physiologically.

They may excel cognitively (displayed as insight, analysis, achievement) but struggle with:

• Interoceptive cues

• Downshifting arousal

• Tolerating emotional intensity

  
  

Emerging research in somatic psychology and polyvagal theory suggests that sustainable mental health depends not only on cognitive reframing, but on autonomic flexibility - the ability to move between activation and rest without getting stuck.

Without this skillset, substances can feel like the only accessible switch.

What Helps Build True Regulation?

Somatic regulation is slower than substances, but it is cumulative.

Examples include:

• Breath pacing that lengthens the exhale

• Rhythmic movement (walking, bilateral stimulation)

• Cold-to-warm contrast exposure

• Structured routines that reduce decision fatigue

• Environmental order, texture, and soft lighting

• Safe relational co-regulation

Clinical studies in trauma treatment and stress physiology demonstrate that repeated bottom-up interventions can recalibrate stress response systems over time.

The nervous system can learn safety.

But it learns through repetition, not force.

Harm Reduction Matters

For some individuals, immediate cessation of substances is neither realistic nor clinically indicated. A harm reduction framework recognizes that behavior often changes once regulation capacity increases.

The question shifts from, “Why are you using this?”

to, “What is your nervous system trying to solve?”

That shift alone can reduce shame. Shame itself is a driver of dysregulation.

Summary

Substance use is often an attempt at nervous system regulation. While it may provide temporary relief, it can gradually impair mood stability and stress tolerance. Building somatic regulation skills increases autonomy, resilience, and long-term mental health stability.

Reflective Questions

• When I reach for a substance, what state am I in physiologically?

• Do I know how to downshift my nervous system without external aids?

• What sensations feel intolerable in my body?

• What small, repeatable regulation practices could I experiment with this week?
