Hot flashes: when your brain regulates body temperature incorrectly

Your body is an amazing thing, a biological marvel where multiple systems work together to keep you healthy and help you function in highly complex environments. Sometimes, however (like during menopause and the years leading up to it) your body makes mistakes, resulting in symptoms like hot flashes and night sweats.

Hot flashes are thought to occur when changes in hormone levels cause the brain to "go rogue" as it attempts to regulate body temperature. As explained by the North American Menopause Society (, hot flashes occur when your brain falsely believes your body is too warm, which starts a chain of events to cool it down. Your brain signals blood vessels to expel heat quickly through your skin, creating redness in the face and neck. Your sweat glands begin perspiring heavily, and your heart rate may race to pump blood faster through your body. These episodes typically last 30 seconds to 5 minutes or more, and they can be stressful, fatiguing, and embarrassing, especially when they happen in professional settings.

When you're having problems regulating body temperature, commonly suggested recommendations include hormone replacement therapy, prescription meds, lifestyle changes, and yoga. One big problem with all of these options, though, is that they're not able to deliver immediate relief when you need it most, right when you're having a hot flash.

That's where Embr Wave® from Embr Labs can help. The Wave is a smart wristband that instantly provides on-demand cooling at the press of a button—anywhere and anytime.

Find thermal relief with Embr Wave

Embr Wave offers a convenient, discreet, and effective solution for anyone experiencing issues regulating body temperature, whether they're too hot or too cold. While it may resemble a smartwatch or an elegant bracelet, the Wave contains a powerful thermoelectric heat pump within its sleek exterior. The heat pump uses a patented control system to generate precisely engineered patterns of warm or cool sensations that you feel on your inner wrist, where thermoreceptors in your skin are highly sensitive to temperature. Your body responds to these sensations by sending a feel-good signal to your brain, prompting your body to rebalance how hot or cold it feels and quickly restore your comfort.

How can local thermal sensations provide full-body comfort?
To provide relief when your brain regulates body temperature incorrectly, Embr Wave takes advantage of a physical phenomenon you likely already understand well. Think of how, on a scorching summer day, just dipping your toes into the cold water of a pool can make your entire body feel cooler. Or how wrapping your hands around a cup of hot coffee on a cold winter's morning can allow you to feel warmer all over. Studies show that these concentrated bits of warming or cooling on sensitive parts of your skin can change your perceived comfort throughout your body, meaning you can get powerful, full-body relief using just a little bit of temperature in the right spot.

Does the Wave regulate body temperature?

Embr Wave doesn't regulate body temperature—only the brain's hypothalamus can do that. The hypothalamus is your body's internal thermostat, responsible for keeping your temperature close to 98.6°F. Surprisingly, your core body temperature doesn't usually go up during a hot flash (in fact, core temperature often decreases slightly after a hot flash). The extreme feelings of heat and discomfort come from the sequence of actions that your brain puts into motion when it incorrectly believes your body is overheating: rapidly dilating blood vessels, flushing of the skin, excessive perspiration, and increased heart rate. This "misfiring" of the brain's temperature regulation center is thought to be caused by decreased levels of estrogen during menopause.

If the Wave doesn't regulate body temperature, how does it work?
Embr Wave uses hot and cold therapy to provide instant relief when your brain's temperature regulation goes awry. It generates pleasing warm or cool sensations in specific patterns that, when registered by the sensitive skin of the inner wrist, send a feel-good signal to the hypothalamus. This signal prompts the brain to recalibrate your body's perceived temperature, bringing you back into balance and helping you feel more comfortable. In other words, when your brain has mistakenly put your body into panic mode during a hot flash, for example, cooling sensations from the Wave trigger a counter reaction that says, "Hey, we feel nice and cool—there's no emergency here!"

In addition to hot flashes, Embr Wave assists with other conditions caused by the brain's mistakes as it regulates body temperature, like heat therapy for cold flashes and menopause chills as well as thermotherapy for insomnia.

All-day comfort. Easier sleep. Lower stress.

In addition to offering relief when you're having difficulty regulating body temperature, Embr Wave provides a number of other benefits.

Comfort on demand
No matter where you go or who's in charge of the thermostat, Embr Wave puts immediate warmth or cooling at your fingertips. With the press of a button or a tap in the app, you can rebalance your sense of temperature, giving you more control over your comfort level. A UC Berkeley study found that participants who used the Wave for just three minutes were able to adjust their perceived temperature by 5°F warmer or cooler on average. Women found even greater results with Embr Wave, feeling up to 9°F cooler and 6°F warmer.

A better night's sleep
The quality of your sleep is closely tied to temperature. That's why Embr Wave offers thermal sessions designed to get you to sleep faster and stay asleep longer. Fall Asleep sessions use gently slowing sensations to lull your body to sleep more quickly, while All Night sessions feature steady waves at just the right temperature to keep you resting easy through the night.

Relief for stressful moments
Temperature can also be a powerful tool for combating stress and anxiety. Just as a warm bath or a cold compress can relax your body and calm your nerves, the Wave lets you activate soothing cool or warm sensations designed to tap into a neural pathway that can help you destress during difficult moments of the day.

What regulates your body temperature?

The hypothalamus is the part of the brain that's responsible for regulating body temperature. It constantly monitors to see whether you're too warm or too cold. If your temperature is too low, the hypothalamus triggers actions like causing blood vessels to constrict to conserve heat, leading you to feel chilled. When your temperature is too high, the hypothalamus dilates blood vessels to expel heat and activates the sweat glands in an attempt to cool down. At times, the hypothalamus can have difficulties regulating body temperature accurately due to certain medical conditions or injury. During menopause, hormonal changes in a woman's body can cause the hypothalamus to mistakenly believe the body is overheating and must cool down quickly, triggering a hot flash.

Does Embr Wave help regulate body temperature?

No—and because of the way our bodies experience temperature, it doesn't need to in order to bring effective relief. Embr Wave generates carefully engineered warm and cool sensations that are felt on the sensitive skin of your inner wrist. These sensations trigger a natural reaction that causes your brain to recalibrate your sense of comfort, rapidly changing your perceived temperature by as much as 9°F.

Is Embr Wave safe to use?

Yes. The warm and cool sensations generated by the device are as safe as touching a warm mug of coffee or a cold glass of ice water.
