Heart Rate Variability Biofeedback for Substance Use Disorder: Health Policy Implications

Area of Science:

• Neuroscience
• Psychology
• Public Health

Background:

• Substance use disorder (SUD) is characterized by relapse, often driven by physiological processes interacting with affective states and environmental cues.
• Current SUD treatments focus on cognitive and affective control but do not directly address underlying physiological vulnerabilities.
• Automatic physiological dysregulation in SUD compromises effortful self-control, hindering recovery.

Purpose of the Study:

• To introduce Heart Rate Variability Biofeedback (HRVB) as a complementary intervention for SUD.
• To highlight HRVB's potential to directly target physiological deficits in SUD.
• To discuss the evolution of HRVB into an ambulatory intervention with just-in-time support capabilities.

Main Methods:

• HRVB utilizes rhythmic breathing exercises to enhance physiological self-regulation.
• The intervention has transitioned from clinic-based to ambulatory settings using wearable biosensors and smartphone applications.
• Evidence supporting HRVB efficacy in SUD is emerging.

Main Results:

• HRVB directly addresses physiological deficits that interact with affective states and environmental triggers in SUD.
• Ambulatory HRVB offers potential for just-in-time support in self-regulation.
• Existing evidence suggests HRVB's efficacy in supporting SUD treatment.

Conclusions:

• HRVB is a promising adjunctive therapy for substance use disorder.
• Further research is needed to fully establish HRVB's role in SUD recovery and inform policy.
• The development of ambulatory HRVB enhances its accessibility and potential for continuous support.
