Immediate relief from hot flashes
The Héra device works in seconds to soothe hot flashes as soon as they appear thanks to cryotherapy.
Sleep finally restored
No more waking up in a sweat. By reducing night sweats, Héra helps you regain calmer, longer, and truly restorative nights.
Less daily stress
The sensation of coolness sends a calming signal to the body, so you can go through hot flashes more serenely.
Rapidly soothed redness
The targeted action of the cold immediately calms skin redness caused by hot flashes. The result: a more even complexion and restored comfort.
Héra relies on the benefits of cryotherapy*: targeted, controlled cold that stops the sensation of heat in a matter of seconds.
Its patented thermoelectric technology, the result of 2 years of research conducted by engineers and healthcare professionals, generates a thermal signal at 0°C, which is safe for the skin.
Applied to a thermosensitive area such as the face, forearms, or chest, the cold stimulates the cutaneous thermoreceptors.
These sensors send a signal to the hypothalamus, the brain’s temperature regulation center, triggering a natural response that stops hot flashes and helps the body regain its balance.
*Héra is a wellness device: it does not replace medical advice.
This natural practice is part of a holistic approach to well-being and helps to better manage common discomforts.
1. Activate Héra simply by pressing the ON / OFF button.
2. Apply it to a heat-sensitive area: the back of the neck, face, or chest, depending on what feels right for you.
3. Let it work for a few seconds: the cooling sensation spreads quickly, and its effects last for about ten minutes after use.
