FAQ

Does it really help with period cramps?

Heat is one of the most widely used ways to ease menstrual cramps: it helps relax the muscles and boosts blood flow. ulmena adds gentle vibration massage and lets you keep the heat on while you move.

How hot does it get?

You can choose between 3 levels: 113°F, 131°F and 149°F. Start on the lowest and go up if you need more warmth.

How long does the battery last?

Up to 2 hours per charge. It recharges with the included USB cable.

Can I fall asleep with it on?

It switches off automatically after 30 minutes. Even so, we recommend using it while you're awake and always over a thin layer of clothing.

Will it fit me?

The adjustable strap fits waists up to 50 inches.

Can I wear it under my clothes?

Do I get anything else with my order?
