Introduction

Sleep plays a critical role in our overall health, and the quality of our breathing can significantly affect our sleep patterns. BREATHER Inc., headquartered in Minato, Tokyo, has developed a deep breathing support device called the Ston S. This article discusses a collaborative study conducted alongside Brain Sleep to investigate the effects of deep breathing on sleep quality, specifically when utilizing the Ston S device before bed.

Study Background

BREATHER has always focused on promoting deeper breathing habits through innovative technology. After a successful study indicating that deep breathing during sauna sessions yielded positive results, the company sought to explore how this practice could benefit sleep. In a recent study conducted from January to February 2025, twenty participants aged between 20 and 60 were involved in a crossover trial. The subjects utilized the Ston S device for approximately 20 minutes before bedtime, comparing their experiences with nights of regular sleep without deep breathing practices. The goal was to analyze the impacts of deep breathing on various sleep-related metrics by measuring subjective assessments through questionnaires, alongside objective data derived from EEG and autonomic nervous system evaluations.

Subjective Findings: Questionnaire Responses

The subjective evaluation of sleep quality was performed using the OSA Sleep Questionnaire. The results indicated that individuals using the Ston S before bed reported significantly better scores in three main areas compared to nights without the device:

1. Morning Sleepiness - Enhanced wakefulness upon rising.
2. Sleep Onset and Maintenance - Improved ease of falling asleep and deeper sleep.
3. Fatigue Recovery - Feeling more refreshed upon awakening.

Objective Findings: EEG Analysis

Utilizing EEG to assess the sleep stages of participants revealed significant findings. The results indicated that using the Ston S led to a notable reduction in awakenings during the night and an increased percentage of deep sleep (Stage 3 Non-REM sleep). Furthermore, within the critical first cycle of sleep, known as the 'Golden 90 Minutes,' the proportion of deep sleep also increased, underscoring the benefits of enhanced breathing techniques before sleep.

Autonomic Nervous System Insights

A separate analysis focused on heart rate variability (HRV), particularly RMSSD, to gauge the activity of the parasympathetic nervous system. Findings showed that the use of the Ston S before bedtime led to higher HRV, indicating a state of increased relaxation and predominance of the parasympathetic nervous system. This suggests that deep breathing practices enhance autonomic nervous activity, consequently leading to improved relaxation.

Conclusion

The Ston S deep breathing support device serves as an effective tool for promoting deep breathing habits that enhance overall sleep quality. By encouraging a relaxed state through focused breathing before bed, the Ston S empowers users to invest in their sleep health. The comprehensive findings from subjective and objective measures confirm the potential benefits of integrating deep breathing practices into nightly routines.

As we continue to explore the relationship between breathwork and well-being, BREATHER is committed to producing devices that facilitate healthier lifestyles and encourage the daily practice of deep breathing. The overarching goal remains to support individuals in achieving a state of optimal physical and mental health through mindful breathing techniques. Together with partners like Brain Sleep, we look forward to uncovering further long-term effects and benefits of deep breathing habits for improved sleep outcomes.
