1. Understanding hot flashes

Hot flashes are caused by a disturbance of the hypothalamus, the region of the brain that regulates body temperature. During menopause, the drop in estrogen leads to hypersensitivity to internal variations, causing sudden vasodilation (widening of blood vessels), followed by sweating and a sudden sensation of heat.

• 80 to 85% of menopausal women experience hot flashes.
• On average, a woman can have 10 to 15 per day, for over 7 years.
• 1 in 2 women considers these symptoms extremely bothersome.

2. Why cold acts quickly: the mechanisms

Cold acts through several physiological mechanisms:

• It triggers vasoconstriction: blood vessels contract, reducing the sensation of heat.
• It slows down nerve conduction, which decreases the perception of pain or thermal discomfort.
• It locally lowers skin temperature, providing an immediate cooling effect.

3. What studies say about targeted cooling

Portable neck device:

A pilot study conducted on 40 perimenopausal women (≥ 7 hot flashes/day) showed no statistical difference between the active device and the placebo regarding the frequency and severity of hot flashes after 4 weeks.

However: 70.6% of women using the active device felt subjective relief, compared to only 22.2% with the placebo. (Read the rest of the article).

Nocturnal forehead device

A small exploratory trial on 20 women suffering from insomnia and hot flashes showed a trend toward improvement in perceived sleep and symptoms thanks to nocturnal forehead cooling. (Read the rest of the article).

International recommendations (NAMS, 2023)

According to the North American Menopause Society (NAMS), hormone therapy remains the most effective treatment for vasomotor symptoms (hot flashes, night sweats).

Non-hormonal solutions (cognitive therapies, certain non-hormonal medications) are also recognized.

Cooling techniques, meanwhile, are viewed as adaptation and comfort tools, useful for some women, but robust scientific evidence remains limited.

4. Sleep, mood, pain: indirect benefits linked to cold

Sleep: Lowering skin temperature in the evening facilitates falling asleep for some people and may limit awakenings related to night sweats. Pilot trials of forehead cooling suggest better perceived sleep. PubMed

Mood/stress: By reducing acute discomfort (thermal peak), cold can diminish immediate distress and promote better tolerance of the episode; regarding non-hormonal treatments, approaches like hypnosis/CBT also have positive data on the perception of hot flashes and quality of life. The Menopause Society

Pain/inflammation: Local cold has an analgesic/anti-inflammatory effect well described in other contexts (sports, postpartum). For example, after childbirth, cold perineal packs reduce pain for 1h45–2h (clinical trials). Transposed cautiously, this logic supports the local use of cold for painful areas during menopause.

5. A cautious look: perineal cryotherapy

"Perineal cooling" (type of cold packs/derivative baths) is well-documented in postpartum for perineal pain and edema. However, specific menopause data is lacking: one extrapolates a mechanism (vasoconstriction → decongestion → analgesia), but to date, there are no robust clinical trials among menopausal women on this protocol. If considered, it must remain short, clean, non-aggressive, and interrupted in case of discomfort.

6. Scientific evidence for the effect of cold

Menopause study (2022)

A pilot trial was conducted on 15 menopausal women suffering from hot flashes and night sweats. For 8 weeks, they used a forehead cooling device every night.

Results:

• Vasomotor symptoms (hot flashes + sweats) decreased by 52%.
• Sleep quality improved significantly (measured with the PSQI index).
• Women also reported a reduction in the impact of hot flashes on their daily lives.

Behavioral Sleep Medicine study (2019)

This pilot study included 20 menopausal women suffering from insomnia linked to hot flashes. They used a nocturnal forehead cooling device.

Results:

• Participants noted an improvement in their sleep.
• A downward trend in nocturnal hot flashes was observed.
• Although the sample was small, the results are encouraging and pave the way for larger studies.

Cryotherapy is already recognized for its effects on:

• Muscle recovery
• Chronic pain
• Inflammation
• And now, hormonal disorders

7. A natural, rapid, and safe response

Unlike hormone treatments:

• There are no side effects associated with well-supervised use of cold.
• Relief is almost immediate (less than 10 seconds in some cases).
• It is non-medicinal, 100% natural, and recommended for at-risk women (hormone-dependent cancer, family history, etc.).

10. FAQ: Héra Device

1. How can hot flashes be relieved naturally?

Hot flashes are one of the most common and debilitating symptoms of menopause. Several solutions exist to alleviate them naturally:

• Adjust your diet: favor foods rich in phytoestrogens (soy, flaxseeds, chickpeas), and reduce caffeine, alcohol, and spicy foods that aggravate hot flashes.
• Adopt a healthy lifestyle: practice regular physical activity, and prioritize relaxation (yoga, meditation, breathing).
• Try medicinal plants: sage, red clover, black cohosh... some women find partial relief, even if results vary.
• Use targeted cryotherapy with Héra: this innovative device provides immediate relief in seconds, without drugs or hormones.

2. How long do hot flashes last?

The duration of hot flashes varies greatly from one woman to another:

• On average, they last between 2 and 7 years.
• In about 20% of women, they can persist for more than 10 years.
• In rare cases, some women report symptoms even after the age of 70 or 80.

Their intensity is not constant: they may be very frequent at the beginning, then decrease gradually. Natural solutions like Héra help reduce the discomfort in daily life.

3. Do all women experience menopause in the same way?

No. Every woman experiences menopause in a unique way:

• Some only feel minor, occasional hot flashes.
• Others suffer from a combination of symptoms: insomnia, night sweats, joint pain, mood swings, vaginal dryness, decreased libido, anxiety...
• The age of menopause also influences symptoms: early menopause (before age 40) can be more abrupt.

4. Why avoid Hormone Replacement Therapy (HRT)?

HRT (hormone replacement therapy) remains effective for some women, but it also carries documented risks:

• Increased risk of certain cancers (breast, endometrial).
• Cardiovascular risks (thrombosis, stroke).
• Possible side effects: headaches, nausea, bleeding, leg swelling.

Many women today prefer to turn to natural solutions like Héra, which offer immediate relief without hormonal side effects.

5. Is Héra covered by Social Security?

For the moment, Héra is not covered by Social Security or health insurance plans. However, the startup Athana offers:

• A "30-day money-back guarantee" to allow you to test it without risk.
• A 2-year manufacturer's warranty.
• A permanent promo code (MENO10) to get 10% off.

Even without official reimbursement, Héra remains an accessible alternative compared to the repeated cost of certain medications or ineffective supplements.

6. Can Héra completely replace medical treatment?

No. Héra is not a medical device, but a natural wellness solution. It:

• Effectively relieves symptoms related to hot flashes.
• Improves daily comfort and quality of life.
• Can be used alongside medical supervision.

It does not replace a treatment prescribed by a doctor for complicated menopause, but it constitutes a natural and innovative alternative for all those who wish to avoid or reduce hormonal treatments.
