😱PTSD – The role of Exercise🏃

PTSD and Exercise Part 2:
The Physiology of PTSD and Exercise

The importance of Exercise for PTSD

PTSD is a nightmare to live with and the recovery is hard work. For an insight of what it’s like you can read Part 1.

Not only do the sufferers live with PTSD, having the condition places them at an increased risk of other health issues.  Isolation and loneliness (due to avoiding triggers), alcoholism (an escape tactic), and physical inactivity (exacerbated by fear of triggers, depression and fatigue) increase the probability of developing:
  • High Blood Pressure
  • Cardiovascular Disease
  • Type 2 Diabetes
  • Obesity
  • Chronic Pain
  • Bone and Joint Disease
  • Neurological conditions
  • Respiratory conditions

It is common knowledge that exercise is helpful in the treatment and prevention of the above conditions.
This alone emphasises the importance of exercise for PTSD.

HOWEVER, over the last few years exercise is becoming recognised as a strong influence in the treatment of PTSD as well!

 

The Physiology of Exercise and PTSD:
The Current Theories of How Exercise Works

Home-made happy chemicals

  • Endocannabinoids (eCB).

Did you know that the human body actually produces it’s own (endogenous) cannabinoids? Exercise stimulates eCB and it is involved in mood regulation as well as memory, focus, pain, fear processing and stress adaptation. Bonus: endocannabinoids do not have side effects like exogenous versions.

  • Endorphins and Neurotransmitters.

There is a rumour that exercise increases endorphins, serotonin, anandamide, beta-endorphins and dopamine. Evidence has supported this for 40 years. However, the intensity of exercise and mood improvements appears to be individualised.

The Nervous System

  • Neuroplasticity

Exercise enhances neuroplasticity. Neuroplasticity is essentially the mechanism behind “re-wiring” the brain including its conscious and unconscious thoughts. (We have a whole article on Neuroplasticity coming up next month!)

  • Nervous System Stress Tolerance

Increased fitness is associated with healthier nervous system tolerances (fight/flight/freeze response) evidenced by improvements in HRV, (which Specialised Health is quick becoming specialists in).

Biopsychosocial

  • Bio – Physical symptoms

As exercise has similar symptoms to anxiety, such as increased heart rate, blood pressure and sweating, practicing exercise can support the individual in becoming comfortable with these physical symptoms and not automatically interpret them as a state of panic.

  • Psycho- Increased self-efficacy

Mastering new sport and exercise tasks can assist in improving self-efficacy and eventually self-confidence.

  • Psycho – Mindfulness/presence

Exercise can be a healthy escape from the mind’s processing of the past and current fears.
The mind can focus on learning something new or focus attention on bodily sensations during exercise. This effect can be experienced in all modes of exercise including yoga, stretching, tai chi, resistance training, aerobic exercise, and HITT.

  • Social

Exercise can provide a social environment and assist in increasing social support, combatting the deadly effects of loneliness, as well as improving perceived safety.

The Endocrine System

  • Exercise can assist in normalising the Hypothalamic Pituitary Adrenal Axis (HPA axis). The HPA axis regulates reactions to stress and physiological processes via various hormones.

 

The Immune System

  • PTSD has been shown to be associated with increased inflammatory markers, and aerobic exercise has been shown to reverse these immune cells.

 

Recommendations

Start small, get moving. Even a walk with a friend can help. Increase intensity as soon as appropriate (may need medical clearance).

For optimal results, there are a few things to consider when prescribing the ideal exercise program. For example, physical and psychological contraindications, co-morbidities, preferences and amotivation. Therefore, the gold-standard recommendation is to refer to an Exercise Physiologist,  experienced in PTSD.
