The Science Behind Sigh
Our approach is grounded in Cognitive Behavioural Therapy (CBT), the gold standard for addiction treatment, now optimised for the digital age
Physiological Sigh
A breathing technique that immediately calms the nervous system and reduces craving intensity.
Urge Surfing

Thought Challenges
Identify and reframe the thoughts that trigger vaping. Change your internal dialogue.
Behavioural Substitution
Replace vaping habits with healthier alternatives that satisfy the same psychological needs.

Our methods are backed by decades of addiction research and clinical trials

Empowerment, Not Shame
We believe quitting should be supportive, not punitive. Sigh is designed to give people control over their habits, empowering them to quit at their own pace, without guilt.
Science-Driven Change
Every feature is grounded in behavioural psychology and cognitive behavioural therapy (CBT). We use proven science to break the habit loop and create lasting transformation.
Radical Honesty & Care
Unlike vape companies built to keep people hooked, we exist to help people quit. Transparency, empathy, and user wellbeing guide every decision, from product design to community building.
