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.
For US mainland shipping only, your order will ship within two business days and assuming no unexpected delays, should arrive 3-5 days from the date of shipment.

Kulkuf Operation Related FAQS

KULKUF cools down to 3 discrete temperature points, 45 F(7°C), 50 F(10°C), 54 F(12°C) reached almost instantaneously with easy one-press button operation.
For 9/10 women who tried Kulkuf, KULKUF stopped hot flashes in under 1 minute. Kulkuf works by perceptively, cognitively and actually cooling you down. First, you feel the powerful cooling against your flushed skin. Then, your body starts actually cooling down from the inside out. Lastly, your brain perceives this and shuts down the hot flash immediately.
Yes, it does. Independent research conducted in the renowned Korey Stringer Institute, University of Connecticut, has shown core body cooling of upto 0.5° C with our patented cooling technology, Climacon®, applied at the wrist. Kulkuf is powered by Climacon® with great success in stopping hot flashes in their tracks.
Kulkuf works as an extension of the body’s thermoregulatory system. The slight heat that the body expels using flushing, sweating, etc, is pulled out by Kulkuf using our patented, proprietary Climacon® technology. The heat that kulkuf pulls out from your wrist is what it radiates out from the top of the kulkuf.

Target Audience and Safety Related FAQS

Yes, it does. In all the trials we have conducted and feedback we have received from customers, Kulkuf works for almost anybody suffering from hot flashes due to menopause, andropause or after-effects of chemotherapy for cancer patients.
It won’t. Kulkuf is easy to operate and comes with 3 discrete cooling levels. You can choose any one as per your comfort or switch it off as soon as you feel too cold. Kulkuf is designed to switch off after 5 minutes of operation since that is typically the length of time a hot flash lasts for, so kulkuf is safe to be worn even when sleeping. Another incarnation of Kulkuf, the dhamaSPORT, is a cooling sports wristband designed to be worn continuously during workouts and sports for athletes. dhamaSPORT has been extensively used in the Rio Olympics, in ironman triathlons, cycling world championships, and races worldwide. There has been no indication of the core temperature cooling down more than 0.5°C even with prolonged use.
Yes you can. However, please ensure the top side of your wrist is facing up. i.e., you’re not blocking the heat extractor element that allows kulkuf to pull the heat out of your body.
9/10 people who suffer from hot flashes after chemotherapy have experienced immediate relief with kulkuf.
Typically, a hot flash is gone under 60 seconds with kuluf. However, a lot of women have reported that they feel relief in under 30 seconds.
Kulkuf is an external cooling device that works as an extension of the body’s natural thermoregulation mechanism. It has no known, reported or expected side-effects and is safe to use.

Device Usage Related

The correct way to wear the kulkuf is to make sure the ceramic plate on kulkuf’s underside aligns with the underside of your wrist. This is the cooling unit that pulls out heat from your body. Also ensure the top part of kulkuf is not blocked since that is where the heat escapes from.
