You know the feeling: a stressful moment passes, but your mind keeps racing. We wanted to see what happens in the brain when you take 10 minutes to unwind with Pulsetto.
To find out, Pulsetto Lite was tested in a sham-controlled EEG laboratory study run by Zentrela, a company specializing in EEG-based research. In this study, a single 10-minute Pulsetto Lite session was associated with short-term changes in brain activity linked to relaxation.*
Here is what the researchers did, what they observed, and what it does and doesn't tell us.
How the study worked
Twenty participants took part in a sham-controlled laboratory study. Each person first went through a short, controlled stress task, then used either Pulsetto Lite or a sham (inactive) device for 10 minutes.
- Stress induction: 5 minutes of anxiety-inducing music, followed by a cold pressor test (placing a hand in cold water).
- One session: a single 10-minute session with Pulsetto Lite or a sham device.
- EEG measurement: brain activity was recorded before the session and for up to 120 minutes after it.
- Comparison: EEG-derived measures for Pulsetto Lite were compared against the sham condition.
EEG (electroencephalography) records the brain's electrical activity through sensors placed on the scalp. Researchers use these signals to calculate indicators linked to states such as relaxation and mental arousal. These are measured EEG-derived indicators, which are different from how participants say they feel.
The study looked at short-term responses to one Pulsetto Lite session. It did not assess long-term benefits or other Pulsetto models.
