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.

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.
