Understand the Science

There’s a scientific reason why thermal sensations help you feel better. Each sends a comfort signal to the area of your brain that’s associated with thermoregulation, sensation, and even stress & emotion.

Questions and Answers

  • Can Embr Wave help with menopause or hot flashes?


    We've heard from countless people suffering from hot flashes—whether from menopause, hormonal treatments, or other medical conditions—and looking for any source of relief. We're happy to report that thousands of women and men are now able to use Embr Wave to make hot flashes more bearable and regain control over their thermal comfort.

  • How does Embr Wave warm or cool your skin?

    The Wave uses a battery-powered thermoelectric heat pump that works by moving heat away from or towards your skin using a phenomenon known as the Peltier effect. When you press the cooling or warming buttons, the Wave runs electricity in one direction to cool your skin and the other way to warm your skin. You experience the thermal sensation on your inner wrist via the thermal ceramic plate on the underside of the Wave.

  • Does the Wave change your core body temperature?

    Nope. The Wave is able to help you feel more comfortable without needing to affect your core body temperature. Unless you're actually at risk of hypothermia or hyperthermia, it’s likely that your core temperature is already right where it needs to be, at about 98.6 ºF. Your thermal comfort, then, isn't so much about core body temperature but instead depends on your perception of local thermal sensations across your entire body.

    For example, if you've ever felt too hot while in bed and decided to stick one foot out from under the covers or flip your pillow to the cool side, those actions aren't changing your core temperature—that's still going to be around 98.6 ºF. Instead, they're introducing localized temperature sensations that help change the way you feel overall.

    The Wave gives you the power to create these thermal sensations on demand, anytime, at the press of a button!

  • Why isn’t the temperature feeling steady?

    Embr Wave creates cooling or warming sensations that are designed to come in waves.


    As a result, the temperature will not be a steady or "always on" feeling, but instead will come and go in waves that have been carefully engineered to give you maximum thermal relief in different situations.

    The reason we warm and cool in waves is because the human body responds most significantly to changes in temperature. If the temperature were steady, you would quickly acclimate and stop noticing it—think of how when you jump into a cold pool, it stops feeling cold within a minute or two! Sending the temperature in waves allows your brain to keep noticing that local sensation, bringing your body's thermal focus to your wrist and helping you feel more comfortable overall.

  • Do I need the download the app to use Embr Wave?

    Technically no… but kind of yes.


    Without the app, you can still warm or cool using the controls on your Wave (the buttons on Wave 2 or the light bar on Wave 1). You’ll be able to start and stop sessions or adjust the temperature level up and down, but you’ll be limited to the default 10-minute sessions that come loaded on the device.


    For that reason, we strongly recommend using the app to unlock the full potential of your Wave. The app gives you the power to do things like adjust your session length from 5 minutes to 9 hours; switch to specially designed waveforms for sleep, hot flashes, stress, and comfort; track your patterns over time; customize settings; and get access to device updates and improvements. With Wave 2, the app also lets you assign your two favorite sessions to the buttons on the device for quick access to the relief you need most, whether that's two cooling sessions, two warming sessions, or one of each!

  • What situations is Embr Wave best for? What isn't the Wave good for?

    Embr Wave is optimized to provide relief for those who experience thermal discomfort in moderate environments. Embr Wave won't replace air conditioning in the summer or warm clothes in the winter, and it won't make you feel like you stepped into a freezer on a 90-degree day. (That said, many users still find Embr Wave somewhat helpful under more extreme conditions—it just may not feel as effective as it would otherwise.)

    That means the Wave is perfect for things like:

    🚖 Feeling cool in a stuffy taxi
    🏢 Warming up in a chilly office
    🔥 Calming down a hot flash
    🛌 Staying comfy cool (or snuggly warm) all night long
    🎬 Surviving a sudden cold spell in a movie theater

    🧘‍♀️ Chilling out during moments of stress 

    The Wave isn't designed for situations like:
    🏖️ Cooling while sitting in the sun at the beach
    🏊 Swimming or showering
    🏋️ During a workout
    ♨️ Feeling ice-cold during a heat wave
    ⛄ Feeling toasty-warm in the Arctic
    🌴 Treacherous rainforest expeditions
