Cold flashes

Take control of cold flashes

While hot flashes are usually the headliner when it comes to menopause symptoms, lots of women experience cold flashes as well. During a cold flash, you may find yourself suddenly chilled and shivering, as if someone cranked up the AC or threw the front door open on a subzero day. A cold flash can also happen on the heels of a hot flash as your body tries to rebalance its sense of temperature.

Stress management techniques and changes in diet or lifestyle can help to reduce your experience with cold flashes, but none of these options offers immediate relief when you feel a chill coming on. That's why Embr Labs has developed the Embr Wave®, a smart thermal wristband that can bring instant relief for cold flashes as well as hot flashes, insomnia, night sweats, and other kinds of thermal discomfort.

Embr Wave: warm relief for cold flashes

The Embr Wave is a wristband that looks a bit like a smartwatch or a stylish bracelet. But packed inside its compact exterior is a powerful thermoelectric heat pump that can generate pleasantly warm or cool sensations on demand. These precisely engineered pulses of warming or cooling stimulate a natural connection to the brain that changes the way you perceive temperature and helps you feel more comfortable overall. By simply pressing a button on the device or tapping the mobile app, you can instantly start a series of warm sensations on your skin that bring immediate comfort and relief for cold flashes.

How warmth on your wrist can bring comfort to your body
The Wave taps into your body's instinctual ability to comfort itself with thermotherapy, taking advantage of a physical phenomenon you already know well. Think of how just dipping your toes in a cold pool on a warm day can help you feel cooler overall, or how wrapping your hands around a hot cup of coffee can help your entire body feel warmer. Embr Wave harnesses this natural connection between local sensation and overall comfort, generating precise pulses of warm or cool sensations that send a feel-good message to your brain and help your body recalibrate your sense of temperature.

The causes of cold flashes

Cold flashes are thought to be caused by the same problems regulating body temperature that can trigger hot flashes. During menopause and the years leading up to it, changes in hormone levels can cause your thermoregulation center to mistakenly believe your body is too hot or too cold. In response, your brain creates a hot flash or cold flash in an attempt to rebalance your temperature. In the case of a cold flash, your brain signals your muscles to shiver, raising your body temperature by rapidly contracting skeletal muscles. Additionally, the brain signals your blood vessels to constrict to conserve heat, causing you to feel chilled.

The Wave was shown to be particularly effective for women, who were able to lower their perceived temperature by up to 9°F.

Reduce your stress level
Stress can be significantly impacted by temperature—it's why a warm bath feels so good at the end of a grueling day or how a cold drink can refresh your spirits. Embr Wave gives you the ability to experience similarly therapeutic warm and cool sensations on demand, helping to soothe your nerves and dissipate tension when you feel your stress level rising.


What are cold flashes?

Cold flashes are sudden episodes of tingling, shivery chills that may cause you to shake or become pale. Typically lasting just a few minutes, cold flashes are most commonly associated with hormonal changes during menopause. During this time, fluctuating hormone levels can cause the hypothalamus (which regulates body temperature) to believe the body needs to warm up quickly, resulting in the shivering and chills of a cold flash. Some women experience cold flashes on the tail end of a hot flash, as the body tries to recalibrate its temperature.

How does Embr Wave help with cold flashes?

To bring relief for cold flashes, Embr Wave offers instant heat therapy, generating pleasantly warm sensations on the temperature-sensitive skin of the inner wrist. These thermal sensations send a feel-good signal to the brain which helps to rebalance the perception of temperature throughout the body.

Does the Wave change my core body temperature?

No. During hot or cold flashes, your core body temperature remains around 98.6°F. The thermal sensations generated by Embr Wave simply produce a soothing effect that can help to reset your experience of temperature and deliver instant relief.
