Exercise is a powerful harm reduction treatment — but the dose matters. Research now allows us to be specific about what type, duration, and frequency most effectively addresses harm reduction.
The Research on Exercise Dose for Harm Reduction
Meta-analyses consistently find that for harm reduction:
- Frequency: 3-5 sessions per week is optimal
- Duration: 30-45 minutes per session produces maximum benefit
- Intensity: Moderate (able to talk, but not sing) is sufficient — higher isn't necessarily better for harm reduction
- Type: Aerobic exercise has most evidence; strength training shows growing evidence
Getting Started with Exercise for Harm Reduction
When harm reduction makes motivation low, start with 5 minutes. The hardest part is starting — not continuing.
Exercise works for harm reduction through immediate neurochemical effects (mood boost) and long-term neurological changes (increased resilience).
Exercise as Sustainable Harm Reduction Treatment
Unlike some harm reduction medications, exercise has positive side effects and the benefits increase over time rather than requiring dose escalation.
