OhmBody wearable aims to ease period cramps with ear neurostimulation

OhmBody, a wearable neurostimulation device on display at CES 2026, is being pitched as a way to reduce menstrual period symptoms and cramps without medication.

The device attaches near the ear and targets the auricular branches of the trigeminal and vagus nerves to regulate menstrual cycle symptoms and help the body return to a rested state. The article says these nerves play roles in releasing estrogen and progesterone and affect muscle contraction, blood flow and digestion—functions that change during a period and can increase cramps.

Users can adjust the device's neurostimulation intensity. An OhmBody representative explained the earpiece's stimulation feels similar to a foot falling asleep. The company offers a patented earpiece and a handheld unit resembling a baby monitor, and says users can wear it for two hours on the days they have their period.

The piece notes that a few studies have found vagus nerve stimulation can help people with dysmenorrhea and reduce heavy bleeding. It also places OhmBody alongside other menstrual technologies such as Natural Cycles, Oura Ring and Vivoo's conceptual Flow Pad. OhmBody lists two price points: the Active Kit for $579 and the Classic Kit for $559; the article does not detail broader clinical validation or regulatory status.
