Hot flashes at night

Don't let hot flashes at night ruin your sleep

Hot flashes are uncomfortable anytime of the day, but they're particularly frustrating at night. Your sleep is suddenly interrupted by a feeling of intense heat across your face, neck, and chest. Your heart rate spikes, and you're suddenly drenched in sweat.

A single hot flash at night might only last five minutes or less; but for many people, even one hot flash can lead to hours of sleeplessness followed by fatigue and brain fog the next day.

If you have hot flashes at night—also known as night sweats—you're certainly not alone. About 70% of women experience hot flashes and night sweats during menopause and perimenopause. And cancer patients are often troubled by these same symptoms.

Traditional remedies for hot flashes and night sweats include hormone therapy, medications, significant lifestyle changes, and more. But today, many people are finding nearly instant relief through science—with a thermal wristband called Embr Wave®.

Get relief from hot flashes night and day with the Wave

The Wave from Embr Labs is a wearable technology that helps you regulate your temperature experience. The Wave uses a compact thermoelectric heat pump to create a series of warm or cool sensations on the temperature-sensitive skin of your inner wrist, allowing you to feel more comfortable overall and delivering instant relief from hot flashes at night or during the day.

How it works

A hot flash happens when your brain receives a false signal to expel heat from your body. The Wave counters this by creating a cooling sensation on the skin, which then sends a feel-good message to the part of your brain that's associated with sensation, pleasure, thermoregulation, stress, and emotion. Your body's built-in response to temperature sensations on the skin brings relief for hot flashes and helps you feel more comfortable.

Cooling on your wrist, comfort for your whole body
Amazingly, concentrated cooling or warming on one small spot on your wrist can change how you feel overall, without changing your core body temperature.

Relief with the press of a button
When you feel a hot flash coming on, simply press the cooling button on the Wave. Patented technology in the device immediately starts generating a series of pleasantly cool sensations on your inner wrist for 5 minutes up to 9 hours at a time.

Backed by scientific studies
The positive effects of the Wave on hot flashes at night have been studied by Johnson & Johnson Innovation, UC Berkeley, and other partners. Study participants saw a 168% improvement in their ability to control hot flashes, and a 28% reduction in the time it took them to fall asleep.

Why do I get hot flashes at night?

While hot flashes can be caused by a variety of things, they most commonly occur during menopause or perimenopause. It's thought that hormonal changes may cause your internal thermostat to mistakenly believe your body is too warm. This sends signals to your brain that start a chain of events where your body tries to expel excessive body heat. The blood vessels near the surface of your skin get wider to try to cool your body down. Your heart beats faster and your sweat glands start working overtime.

During the day, hot flashes can be so severe that they make it impossible to go about your daily activities. Many people find that hot flashes can be even worse at night, waking them up, leaving them drenched in sweat, and making it tough to fall back asleep. The changes in hormones thought to affect hot flashes are often more pronounced at night.

Hot flashes and night sweats can last for months or years. While a small percentage of women never get hot flashes, others experience them for a decade or more. Traditional treatment for severe hot flashes and night sweats may include hormone replacement therapy, prescription medication, or changes in diet like avoiding alcohol, spicy foods, and caffeine. Natural remedies may include things like acupuncture, supplements, meditation, or yoga.

Fortunately, the Wave offers a much easier—and often more effective—way to find instant and natural relief for hot flashes any time of the day or night.

How the Wave delivers relief

The Wave is a low-power, completely silent wearable that warms or cools the skin on the inside of your wrist. While it looks like a smartwatch, it's actually a high-tech, thermoelectric heat pump that warms or cools your skin with precise thermal sensations designed to improve your experience of temperature and your sense of well-being.

It's like a mini air conditioner or heater
The Wave uses electricity generated by a rechargeable lithium-ion battery to safely move heat or cold away from your skin. A patented control system and temperature sensors generate precise thermal sensations that can be adjusted to help you find your ideal comfort level. When it comes to hot flashes and night sweats, it's like having a personal cooling system at your fingertips. And because it's so discreet, you can cool down from a hot flash without anyone else having to know.

Engineered temperature
The Wave's custom sensations, known as Waveforms, are carefully engineered to optimize the sensation you get from each pulse while reducing the amount of power needed to produce them. That means you can stay cooler, longer, on a single charge.

Meet the app
The Wave 2 mobile app gives you more control over your temperature experience. Explore recommended thermal sensations for any situation, reprogram your Wave's buttons and lights, or configure your own settings to create a thermal experience that's just right for you.

Better sleep. Less stress. More comfort.

In addition to bringing relief for hot flashes, the Wave can help improve sleep, reduce stress, and help you feel more comfortable.

How it works

Better sleep
Gentle, soothing waves at just the right temperature can help lull you to sleep and keep you comfortable at night.

Greater comfort
The Wave can change your perceived temperature by up to 9°F, so you can control how you feel no matter who's in charge of the thermostat.

Lower stress
Relaxing warm or cool waves can help you feel calmer and more collected when your stress level begins to rise.


What are hot flashes?

A hot flash is a feeling of intense warmth, usually across your face, neck, and chest. It can be accompanied by an increase in your heart rate, heavy sweating, and agitation. Hot flashes are thought to most often be the result of hormonal changes that cause your internal thermostat to sense that your body is too warm. When your brain receives these signals, it reacts by increasing the width of the blood vessels near the skin's surface, causing you to feel suddenly warm. It also quickens your heart rate and revs up your sweat glands.

Why do hot flashes feel worse at night?

Hot flashes at night often feel stronger than similar episodes during the day. This may be because of higher hormone levels in the body at night, or because of warm bedding or the temperature in the room. Consuming alcohol and spicy foods before bedtime may contribute to hot flashes at night, and stress is thought to increase the severity of hot flashes.

How can cooling on my wrist affect temperature throughout my body?

Studies have shown that even a small, localized sensation on your wrist can change your comfort level and your perceived temperature throughout the body. The warming or cooling sensations generated by the Wave send a feel-good message to your brain that can quickly adjust your perception of temperature to help you feel better in just a few seconds.

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 if already right where it needs to be, about 98.6°F. Outside of extreme circumstances, thermal comfort isn't 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°F. Instead, they're introducing localized temperature sensations that help change the way you feel overall. The Wave gives you the power to create these localized sensations on demand, anytime!
