Key result
Cotinine-confirmed tobacco relapse is linked to shorter sleep, higher resting HR, and lower HRV.
Why the study?
Smoking cessation is often assessed using clinical and self-report measures that may not capture autonomic changes.
Do wearable physiological signals (sleep duration, resting heart rate, HRV) differ between individuals who relapse and those who maintain smoking cessation?
Observational (n=28)
Do wearable physiological signals (sleep duration, resting heart rate, HRV) differ between individuals who relapse and those who maintain smoking cessation?
Standardized Mean Difference: 0.97
p-value: p=0.016
Wearable physiological monitoring can detect autonomic changes associated with smoking relapse, suggesting utility as a complement to traditional clinical and self-report assessments.
Wearable sleep/HRV differences may flag relapse risk; hypothesis-generating and requires validation before any clinical use.
Background Smoking cessation is often assessed using clinical and self-report measures that may not capture autonomic changes. Wearables allow continuous monitoring.Methods Twenty-eight smokers underwent 10 days of monitoring of sleep duration, resting heart rate, and HRV. Cotinine-confirmed relapse (n = 15) and maintained cessation (n = 13) groups were compared across physiological, clinical, and wearable index measures.Results Participants who returned to tobacco use showed shorter sleep duration, higher resting heart rate, and lower HRV (all p-values < 0.05). The wearable index was higher in the relapse group (p = 0.016, g = 0.97).Conclusions Wearable measures may complement clinical and self-report assessments during smoking cessation.

Шошина et al. (2026) conducted an observational in Smoking cessation (n=28). Cotinine-confirmed relapse vs. Maintained cessation was evaluated on Wearable index (g = 0.97, p=0.016). Cotinine-confirmed relapse to tobacco use was associated with a higher wearable index (g = 0.97, p = 0.016), shorter sleep duration, higher resting heart rate, and lower HRV.
