Wearable Ultrasound Patch Boosts REM Sleep Without Medication or Surgery

Topic: Health

Researchers from the University of Texas at Austin created a soft wearable patch called NEUSLeeP that improves REM sleep without medication or surgery. The patch uses gentle ultrasound stimulation and tracks brain activity in real-time. In a study involving 28 people, participants entered REM sleep 43 minutes sooner and stayed in that stage for about 16 minutes longer.

Researchers led by the University of Texas at Austin have created a soft wearable patch called NEUSLeeP. This patch uses gentle ultrasound stimulation to improve REM sleep without medication or surgery.

The researchers tested the technology in a study involving 28 people. The results showed that participants entered REM sleep 43 minutes sooner and stayed in that stage for about 16 minutes longer. The benefits were observed in both healthy sleepers and those with some sleep difficulties.

The patch is comfortable to wear, and users reported minimal adverse effects. Brain imaging revealed changes in circuits associated with emotion, suggesting that the technology could support mood regulation and psychological resilience.

Why It Matters

This breakthrough has potential implications for stress and emotional health. REM sleep disruptions are linked to depression, anxiety, and post-traumatic stress disorder (PTSD). If successful, this wearable patch could help millions of people get restorative sleep.
