Frequently Asked Questions


KÜLKUF is the only product offering a natural solution to hot flash symptoms by lowering the body’s core temperature. ClimaCon, the science behind KÜLKUF, was independently tested at the world-renowned Korey Stringer Institute where it demonstrated a statistically significant reduction in the core body temperature following testing of our patented cooling technology.

Yes! Our ClimaCon cooling technology was the recipient of many prestigious awards that includes: “MIT Innovators under 35 Award”; 1st place “International CES”; “Global Red Herring Award” and “Launch It”, just to mention a few.

KÜLKUF was tested on over 100 women with hot flashes, and 9 out of 10 participants described a substantial reduction of hot flash symptoms in less than 60 seconds. Many women tested said their symptoms began to subside in less than 30 seconds. Additionally, we confirmed our ClimaCon cooling technology with independent testing at the world-renowned Korey Stringer Institute, who reported a statistically significant reduction in the body core temperature using our patented ClimaCon cooling technology.

Clinical testing involving a large group of menopausal females verified that the symptoms of hot flashes were resolved in less than 60 seconds, with many users reporting a noticeable improvement of symptoms in less than 30 seconds.

This depends on both the frequency and severity of your hot flashes. The average menopausal woman has an average of six hot flashes each day, with each one lasting about 3-4 minutes. With a one and a half hour of battery life per charge, you should expect three days of use per battery charge. This time can be either extended or shortened depending on the temperature sitting and usage time.

The patented ClimaCon technology is the engine behind KÜLKUF. Although the physics principles are somewhat complicated, in very simple terms, our unique technology involves placing an electrical current across the junction of two different metals which results in cooling or heating, depending on the direction of electrical flow.

Absolutely. Just place KÜLKUF on your wrist at the first sign of a night sweat and turn it on. KÜLKUF automatically turns off in five minutes, so you can leave in on and return to sleep or remove it and place on the nightstand.

We warranty KÜLKUF for one year against defects in materials and workmanship. The battery is warranted for 60 days.

Most females are not willing to take the increased risk of stroke, heart attack and cancer, all of which are associated with HRT (Hormone Replacement Therapy). Until KÜLKUF, there was no effective alternative for the treatment of hot flash symptoms. Additionally, the long term cost of menopausal medications could easily be offset by a one time purchase of KÜLKUF.

KŰLKUF wristbands come with a manufacturer defect warranty of one year. The included battery is warrantied for 60 days.


The KÜLKUF wristband can be adjusted in three levels: 45 F(7°C), 50 F(10°C), and 54 F(12°C).

Yes, KÜLKUF wristbands are available in two sizes: Medium and Regular. Regular is the right size for almost 80% of women. However, if you have a smaller wrist, you should choose medium size bracelets. Please refer to the size chart.

The ceramic plate on the underside of the device is where the cooling comes. So it should be aligned with the bottom of your wrist. The top of the wristband is the exhaust element, the area from which the heat escapes; therefore, it should not be blocked.

There are no known, reported, or confirmed side effects. KÜLKUF is an external wearable that works according to the body’s natural thermoregulation mechanism. So yes, it’s absolutely safe.

The technology behind KŰLKUF wristbands is our patented ClimaCon®. Our wristband is a thermoelectric cooler that operates according to the Peltier Effect. To describe the complicated engineering behind this technology simply, a safe amount of electrical current will move between two metals, resulting in the cooling of one junction and the heating of the other.


Night sweats are basically hot flashes during the night, and hot flashes are KŰLKUF’s specialty. Turn on the wristband when you feel a hot flash striking and let the technology do its job. You can go back to sleep as the cooling process starts, and the device will turn itself off after five minutes.

According to our research, 9 out of 10 patients suffering from hot flashes after chemotherapy have experienced immediate relief after using the device. KÜLKUF can therefore help to significantly reduce the annoying chemo-induced hot flashes.

Nine out of ten women had noticed a quick reduction in the intensity of hot flashes in less than 30 seconds. ClimaCon® performance was assessed at the world-renowned Korey Stringer Institute to further prove the effectiveness of our ClimaCon® cooling technology before public release.


An independent study was conducted at the University of Connecticut’s Korey Stringer Institute to test the device. Their findings revealed that Climacon®, KÜLKUF’s patented cooling technology, can reduce body temperature by up to 0.5° C.

Of course, it has! We have received many awards in prestigious competitions for the patented ClimaCon® cooling technology, including but not limited to: “MIT Innovators under 35 Award”, “Global Red Herring Award,” and “Showstoppers LaunchIt” at the “International CES”.


The answer is affirmative. Regardless of gender, anyone can experience bothersome hot flashes for reasons other than menopause. For example, side effects of chemotherapy or hormonal imbalance can cause hot flashes in men or women.

Hormone replacement therapy can come with physical risks such as higher chances of heart attack and cancer. KŰLKUF bracelets will naturally lower your body temperature and provide a safer alternative. Plus, a one-time purchase of the KŰLKUF wristband will save you from spending money on other medications in the long run.

The body’s reaction includes the following phases: First, you feel the cooling effect (flushed skin cools down). Next, the cooling of the body is initiated from the inside out. Finally, the brain perceives these signals and immediately shuts down the heatwave.
