Immediate relief from hot flashes
The Héra device works in seconds to relieve hot flashes as soon as they occur, using cryotherapy.
Sleep at Last
No more waking up in a sweat. By reducing night sweats, Héra helps you enjoy calmer, longer, and truly restful nights.
Less daily stress
The cooling sensation sends a soothing signal to the body and nervous system, naturally reducing anxiety associated with hot flashes.
Quick relief from redness
The targeted cooling action immediately soothes skin redness caused by hot flashes. The result: a more even complexion and renewed comfort.
Héra relies on the benefits of cryotherapy*: targeted, controlled cooling that stops the sensation of heat in just a few seconds.
Its patented thermoelectric technology, the result of two years of research conducted by engineers and healthcare professionals, generates a thermal signal at 5°C that is safe for the skin.
When applied to a temperature-sensitive area such as the face, forearms, or chest, the cold stimulates the skin’s thermoreceptors.
These sensors send a signal tothe hypothalamus, the brain’s temperature regulation center, triggering a natural response that stops hot flashes and helps the body regain its balance.
*Cryotherapy is neither a drug nor a medical treatment.
It does not replace medical supervision.
This natural practice is part of a holistic approach to well-being and helps alleviate common discomforts.
1. Turn on Héra by simply pressing the ON/OFF button.
2. Apply it to an area sensitive to heat: the nape of the neck, face, or chest, depending on how you feel.
3. Leave it on for a few seconds: the cooling sensation spreads quickly, and its effects last for about ten minutes after use.

Cold therapy: a scientifically proven method of relief.
When applied to a specific area of the body, the device emits a thermal stimulus.
The hypothalamus, the part of the brain responsible for temperature perception, receives the stimulus
Your body triggers a natural response that creates an immediate sensation of coolness and well-being
We lacked a non-pharmacological treatment that could be clinically evaluated. Our goal is to scientifically evaluate the efficacy and tolerability of Héra in order to provide solid clinical data for women suffering from hot flashes.Learn about the clinical trial

Hot flashes were relieved with Héra
A mother’s struggle with menopause.
Like 14 million women in France, Marina is experiencing the effects of menopause: hot flashes, insomnia, and night sweats. Moved by his mother’s distress, her son Thaddée created Héra: a natural, hormone-free solution to relieve her symptoms on a daily basis.
We're here to answer your questions.
Where should we put Hera?
For maximum relief, apply Héra to the so-called "thermosensitive" areas, where cold is most effective at soothing hot flashes:
- the back of the neck,
- the chest,
- the wrists,
- or the face.
Simply place the device on a specific area for a few seconds to feel a deep sense of relief.
Depending on the intensity of the hot flash, you can move the device to a different area or repeat the application.
Tip: Everyone’s body is different. Try different areas to find the one that provides the most relief.
Is it portable?
Héra is designed to go wherever you go.
Slip it into your bag, and the device is always within reach: at the office, on public transportation, while traveling, or even on a hike, providing instant relief from hot flashes.
With a 72-hour battery life—enough for up to 50 relief sessions—the Héra device keeps you comfortable wherever you are, whenever you need it.
Is the relief immediate?
Yes, Héra provides relief by lowering the temperature by up to 5°C for a few seconds. Simply place the device on a specific area to experience deep relief from hot flashes.
Depending on the severity of your symptoms, you can:
- Reapply to prolong the refreshing effect.
- Switch areas (neck, chest, face, wrists) for optimal relief.
- Adjust the cooling intensity to one of two levels using the (+) and (-) buttons on the unit.
Has the relief been proven?
Yes, the effectiveness of cold therapy in treating hot flashes has been scientifically proven by dozens of studies. An internal study conducted in 2024 on 100 postmenopausal women confirmed the effectiveness of the Héra device:
96% of women reported being satisfied. An average 32% reduction in hot flashes was observed. An immediate drop in body temperature of 15°C was measured.
These results confirm the effectiveness of localized cooling on heat-sensitive areas for relieving menopausal symptoms, both day and night. Participants also reported a renewed sense of control and reduced stress.
How was the study conducted?
The study was overseen by Athana’s scientific committee. Participants applied Hera’s cooling surface to various heat-sensitive areas: the face, chest, forearms, neck, and nape of the neck.
In addition, a clinical study led by Dr. Alain Toledano, a specialist in radiation oncology and medical director of the Institut Rafaël, has been launched to clinically validate the effectiveness of the Héra device.
Is the device made in France?
Athana is committed to producing Héra through a short supply chain, with the entire process carried out in France: from design to manufacturing, including assembly and logistics.
Assembly is carried out in partnership with the Amipi Foundation, which employs adults with disabilities as part of an inclusive and socially responsible initiative.
This local commitment reflects Athana’s dedication to offering a reliable, responsible solution, carefully crafted in France.
Our customers say it better than we do
On the advice of a friend who uses it, I tried Athena, and honestly, it works.
You should use it when a hot flash starts to intensify and sets in.
It doesn’t make them disappear with a wave of a magic wand—but it’s almost as good. It stops the hot flash from getting worse, and you return to normal very, very quickly. I highly recommend it!
This is such a great invention—ever since I got it, I can't live without it. It's effective, it works wonders—it takes less than 3 minutes, and I feel better right away. I'm so happy with it; I recommend it to everyone. Thank you.
Ultra-fast cooling 👍
Well-designed product with a sleek finish; we'll see how it holds up over time, but it seems high-quality 🙂
For therapeutic use—such as relieving tendinitis—the 1.30' duration is too short; too bad...
I received my little companion🤩 two weeks ago, and she’s been with me everywhere—day and night—and I feel like I’m living again. She lowers my body temperature, and my hot flashes are less intense. I’m sleeping better. I just want to tell women going through a difficult menopause to go for it😜 I love Héra—I can’t live without her anymore. Thank you, thank you, thank you 🙏
I think it's great. I can't take hormones for my hot flashes anymore. I've tried a lot of things, but nothing has managed to reduce them. With this device, they don't last long—it gives me quick relief. Thank you.
It's great. A small revolution. Cravings are significantly reduced—or even nonexistent at certain times of the day—and subside very quickly when using the device.
I'm very happy I made this purchase. I recommend it.
Oh man, perimenopause...
I’m 46, and I’ve been having a lot of hot flashes—I counted six today at work, 😕. When your body suddenly feels like it’s on fire, it’s unbearable. I feel a little too young for this, and the future scares me. So I’ve been trying the Athéna product for the past 15 days, and… Thank you, thank you, thank you! I discreetly place the device on my neck, stomach, and wrist, and the episode passes pretty quickly. I feel like I’m regaining control of my body without medication. In short, I highly recommend it.
Easy to use, convenient—I hope it lasts a long time
A device recommended by a friend.
Very effective, and you can take it with you.
a device that lives up to its promises
The person to whom I gave your device is truly satisfied with the sense of well-being that Hera provides during her hormone therapy, including during her hospital stays. Thank you.
A compact, ergonomic, and effective product: a burst of warmth comes through in 5 to 10 seconds, and it helps me get rid of my redness more easily. Kudos to the young designer!
Well, the cool sensation is perfect—it relieves headaches when a flare-up hits. It’s very convenient to carry around in the pouch—I’d definitely recommend it.
The device is easy to use and compact for travel. It provides real relief and comfort.
Ras
This is a really great invention
It cools you down instantly
Not cold enough for me! And it doesn't last long enough!!!!!
I recommend it 100%
The device does produce cool air, yes, but it doesn't stop the hot flashes, so I'm very disappointed and I don't recommend it.
I really like it—it does a good job of reducing the effects of hot flashes.
Very fast cooler
Improves quality of life during menopause
Just a little small in terms of cooling surface area
Otherwise, it's perfect
When I put the device on, I feel a chill, but it doesn’t necessarily last long, so I move it to a different spot. I feel like it doesn’t have the desired effect right away, but once I take the device off, I notice that my body feels much cooler on the inside—maybe that’s the intended effect. Because of that, it gives me relief.
I would have liked to feel more of a chill and for it to last longer. But I’m satisfied with it.
Given the current heat wave, I think the device would work better if temperatures returned to normal. Nevertheless, it helps me relieve my hot flashes more quickly. Personally, I'd prefer a longer application time and a cooler setting, since I've always had a hard time tolerating the heat.
I'm happy with my purchase
This device really cools me down, even if it's only for a short time
Perfect for relieving migraines
Great product. I'm very satisfied. It provides quick relief.
I'm the daughter of the person who received this device.
It's great—my mom really likes it—but the battery drains very quickly, and the cold isn't as cold as she imagined. Other than that, it's great.
Maybe the battery needs to be checked
I am very, very satisfied...
Try it and you'll love it!
Very effective.
👍
A device that quickly relieves hot flashes
Delighted with how well it works
It's true—the device helps relieve hot flashes.
Since I work as an AESH at a middle school, I use it every class period (it gets hot in the classrooms because there’s no air conditioning) to avoid severe hot flashes that make me feel dizzy. I’ve noticed that after using it, my headaches go away.
