Portable cryotherapy device for hot flushes
Héra

Héra uses patented thermoelectricity. By creating a localized, controlled cooling effect (down to 5°C) on sensitive areas rich in nerve receptors (such as the nape of the neck or the inside of the wrists), the device sends an instant thermal signal to the brain. This thermal shock short-circuits the heat signal sent by the hypothalamus and lowers skin temperature in less than 5 seconds, stopping the hot flash abruptly.

No, absolutely not. Hera is a 100% natural, non-medicinal device. It contains no refrigerant, gas, or chemical product. It does not interfere with your endocrine system and can be used safely on its own or alongside Hormone Replacement Therapy (HRT).

No, the app is 100% optional. You can use Héra completely independently using only the buttons on the device (the indicator lights change from purple to blue to let you know the charge is complete). For those who want it, the app lets you customize the temperature level if 5°C is too cold for your skin and check the battery level precisely.

No, the Héra device is 100% safe and has no medical contraindications. CE and FCC certified, it is perfectly suitable for all women, including during chemotherapy.

• Medical safety: Fully compatible with wearing a pacemaker or any other implanted electronic device.
• Areas to avoid: Do not apply directly to injured or irritated skin, or to an open wound.
• Care & waterproofing: Sweat-resistant, the device must not be submerged or rinsed with water. A simple cleaning with a soft cloth or antiseptic wipe is enough to maintain perfect hygiene.

A full overnight charge provides up to 50 relief sessions of 3 minutes each. This corresponds to a battery life of 3 to 5 days for average use (around 10 to 15 heat bursts per day). The device recharges easily via the included USB-C cable.

Hera has been specially designed to be ultra-compact, lightweight and discreet. It weighs only 200 grams and measures 50x70 cm, so you can easily slip it into a pocket, a handbag, or place it on your bedside table without taking up space.

Hera was designed to support you for the long term. Its lifespan is approximately 7 years, which matches exactly the average length of time a woman experiences hot flashes during menopause. In relation to its price, this represents an investment of about €25 per year (or just a few cents a day). The device is also covered by a 2-year warranty.

The indicator lights built into Héra let you see the device’s status and temperature at a glance.

During use:

• Light blue: Indicates temperature level 1 (10 °C), ideal for a gentle cooling effect.
• Dark blue: Indicates temperature level 2 (5 °C), for a more intense cold sensation.
• Flashing red: Signals the end-of-session cooling phase (the device should no longer be in contact with the skin).
• Green: Indicates that the device is ready for a new session or can be turned off.

During charging:

• Purple: The device is charging.
• Solid blue: The battery is fully charged (100%).

The device is designed to be sweat-resistant. To clean it, simply wipe the metal surface and casing with a slightly damp cloth or wipe. Never submerge the device in water.

The product is very simple and intuitive. However, if you encounter the slightest difficulty or a malfunction, our Fizimed customer service team as well as Athana’s after-sales support team are entirely at your disposal to help you and arrange a replacement under warranty if necessary.
