Temperature is personal, and different people respond differently to Embr Wave. While some may find that everything clicks the first time they try it, others may need more time for their bodies to adjust before the Wave starts to feel effective. We often hear from customers who say they needed to use their Wave for a few weeks before they started to notice a difference — and that it kept working better and better the more they used it! Give your body time, and check out the Embr Wave 2 app to try customizable modes designed for sleep, hot flashes, stress, and comfort to find what works best for you.
