Stress Impacts Your Mental Health More Than You Think BNBA
Not all stress is bad and not all stress is stress. So how do you know if what you’re feeling is something more? Before we can answer that question, we have to understand where stress comes from.

What is Good Stress

Many things in our daily lives cause us stress. The difference between good and bad stress is how long it lasts. Stress that is brief is known as good stress or acute stress.

Good stress helps us grow as humans. It challenges us to expand our physical and mental capabilities as our body and mind rejuvenate in response to stress.

This is one of the principles in exposure therapy. Where short bursts of acute focus on a past fear can desensitize future triggers. This is an example of using a stress response as a tool rather than an obstacle.

Examples of Good Stress

  • A run
  • Doing homework
  • Solving a problem
  • Having a hard conversation
  • Anything that feels difficult but brief

The Key to Recovery

The key to recovery is taking rests in between the spikes of stress. By taking a break and resting the body and mind have time to heal. When there’s no time to heal, stress becomes something different.

What is Bad Stress

Bad stress is also known as chronic stress. This is chronic exposure to adrenaline, cortisol and inflammatory molecules both in the body and mind. It’s a constant state of fight or flight.

When always on high alert, the body adapts in a bad way.

The Body's Response

When this happens, the mind and body are exposed to adrenaline, cortisol, and inflammatory molecules known as catecholamines which drown the rational part of the brain. All of the body’s energy goes to the muscles and vital organs, preparing the body to react. Leaving the mind to starve and fend for itself. Throughout evolution, this is what we needed to run from a bear, this response was good. It was quick. It was and is good stress.

But in the modern world, when this response is chronic and endless and no longer needed, the brain is left without the energy or time it needs to maintain a healthy, positive state.

Physical Signs

Without a break from stress, the rest of the physical body develops:

  • High blood pressure
  • High cholesterol
  • Obesity
  • Etc.

These are the visible signs of long-term, bad stress.

Stress and Mental Illness

As chronic stress becomes inescapable, early signs of mental illness can develop. Conditions like depression or anxiety are the invisible signs that develop alongside the physical, measurable issues.

Changes in Consciousness

Without rest and with no end in sight, our level of consciousness begins to change. The brain simply doesn’t have the energy it needs to sustain its normal function. This change looks like:

  • Negative self talk
  • Doom scrolling
  • Poor hygiene
  • Lack of socializing
  • Increased fear
  • And more

When the mind and body remains inflamed from these stress chemicals for days, weeks, months, or years, the inflammation alters how the body responds to the happy or sad chemicals it produces. This then affects our diet and our willingness to exercise which then affects every other system.
