Hot flashes and menopause: a natural solution that provides relief in 10 seconds using cold

It’s 3 a.m. You wake up in a sweat, your nightgown soaked, your heart racing. Another hot flash. Like nearly 8 out of 10 women going through menopause, these episodes disrupt your sleep, your energy, and sometimes even your mood. It’s rarely discussed, but menopause isn’t “just a phase”: it’s a major neurohormonal upheaval. The good news is that natural, immediate solutions exist, such as the targeted action of cold therapy, which has already been scientifically studied. And that’s where Héra comes in.

FAQ: Héra Device

1. Understanding hot flashes

Hot flashes are caused by a disruption in the hypothalamus, the part of the brain that regulates body temperature. During menopause, the drop in estrogen levels leads to hypersensitivity to internal temperature changes, causing a sudden dilation of blood vessels, followed by sweating and a sudden sensation of heat.

• 80 to 85% of postmenopausal women experience hot flashes.
• On average, a woman may have 10 to 15 a dayfor more than 7 years.
• One in two women finds these symptoms extremely bothersome.

2. Why the cold takes effect quickly: the mechanisms

Cold affects several physiological mechanisms:

• It causes vasoconstriction: the blood vessels constrict, reducing the sensation of heat.
• It slows down nerve conduction, which reduces the perception of pain or thermal discomfort.
• It temporarily lowers skin temperature, providing immediate relief.

3. What the studies say about targeted cooling

Device worn around the neck: 

A pilot study conducted at 40 perimenopausal women (≥ 7 episodes/day) showed no statistically significant difference between the active device and the placebo in terms of the frequency and severity of episodes after 4 weeks.

But: 70,6 % Women using the active device reported feeling relief, compared with only 22,2 % compared to the placebo. (Read the rest of the article).

A small exploratory study involving 20 women suffering from insomnia and hot flashes showed a trend toward improved perceived sleep quality and symptom relief following nighttime 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 treatments (cognitive therapies, certain non-hormonal medications) are also recognized.

Cooling techniques, on the other hand, are viewed as tools for adaptation and comfort that may be helpful for some women, but robust scientific evidence remains limited.

4. Sleep, mood, pain: indirect benefits associated with cold

Sleep: Lowering skin temperature in the evening helps some people fall asleep and may reduce nighttime awakenings caused by night sweats. Pilot studies on forehead cooling suggest improved perceived sleep quality. PubMed

Mood/stress: By reducing acute discomfort (heat peak), cold therapy can alleviate immediate distress and improve tolerance of the episode; among non-hormonal treatments, approaches such as hypnosis and CBT have also shown positive results regarding the perception of hot flashes and quality of life. The Menopause Society

Pain/inflammation: Local cold therapy has a well-documented analgesic and anti-inflammatory effect in other contexts (sports, postpartum). For example, after childbirth, perineal cold packs reduce pain for 1 hour and 45 minutes to 2 hours (clinical trials). Applied cautiously, this logic supports the local use of cold for painful areas during menopause. PubMedPMCScienceDirect

5. A Cautious Approach: Perineal Cryotherapy

" Perineal cooling " (such as cold packs or sitz baths) is well-documented in the postpartum period for perineal pain and swelling. However, specific data on menopause are lacking: a mechanism is extrapolated (vasoconstriction → decongestion → pain relief), but to date there are no robust clinical trials in postmenopausal women using this protocol. If considered, it should be brief, clean, non-aggressive, and discontinued if discomfort occurs.

6. Scientific evidence of the effects of cold

Menopause Study (2022)

A pilot study was conducted among 15 postmenopausal women experiencing hot flashes and night sweats. For 8 weeks, they used a forehead cooling device every night.

Results:

• Vasomotor symptoms (hot flashes and sweating) decreased by 52%.
• Sleep quality has improved significantly (as measured by the PSQI index).
• Women also reported that hot flashes had less of an impact on their daily lives.

Study in *Behavioral Sleep Medicine* (2019)

This pilot study included 20 postmenopausal women suffering from insomnia related to hot flashes. They used a nighttime forehead cooling device.

Results:

• The participants reported an improvement in their sleep.
• A downward trend in nighttime hot flashes was observed.
• Although the sample size is 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 imbalances

7. A natural, fast, and safe solution

Unlike hormone treatments:

• There are no side effects associated with the proper use of cold therapy.
• Relief is almost immediate (in some cases, within10 seconds).
• It is a non-pharmaceutical,100% natural treatment recommended for women at risk (hormone-dependent cancer, family history, etc.).

10. FAQ: Héra Device

1. How can you naturally relieve hot flashes?

Hot flashes are one of the most common and debilitating symptoms of menopause. There are several natural ways to relieve them:

• Adjust your diet: focus on foods rich in phytoestrogens (soy, flaxseed, chickpeas), and cut back on caffeine, alcohol, and spicy foods, which can make hot flashes worse.
• Adopt a healthy lifestyle: engage in regular physical activity and practice relaxation techniques (such as yoga, meditation, and deep breathing).
• Try herbal remedies: sage, red clover, black cohosh… some women find some relief, although results vary.
• Use targeted cryotherapy with Héra: this innovative device provides immediate relief in just a few seconds, without medication or hormones.

2. How long do hot flashes last?

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

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

Their intensity isn't constant: they may be very frequent at first, then gradually decrease. Natural solutions like Héra can help reduce the discomfort they cause in daily life.

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

No. Every woman experiences menopause differently:

• Some women experience only occasional brief hot flashes
• Others experience a combination of symptoms: insomnia, night sweats, joint pain, mood swings, vaginal dryness, decreased libido, anxiety…
• The age at which menopause occurs also affects symptoms: early menopause (before age 40) can be more abrupt.

4. Why should hormone replacement therapy (HRT) be avoided?

Hormone replacement therapy (HRT) 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: headache, nausea, bleeding, swelling of the legs.

Today, many women prefer to turn to natural solutions like Héra, which offer immediate relief without any unwanted hormonal side effects.

5. Is Héra covered by Medicare?

At this time, Héra is not covered by Social Security or private health insurance. However, the startup Athana offers:

• A 30-day "money-back guarantee" so you can try it risk-free.
• A 2-year manufacturer's warranty.
• A permanent promo code (MENO10) for 10% off.

Even without official reimbursement, Héra remains an affordable alternative compared to the recurring costs of certain ineffective medications or supplements.

6. Can Héra completely replace medical treatment?

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

• Effectively relieves symptoms associated with hot flashes
• Improves comfort and quality of life on a daily basis.
• May be used as a supplement to medical care.

It is not a substitute for treatment prescribed by a doctor for complicated menopause, but it offers a natural and innovative alternative for women who wish to avoid or reduce hormone therapy.
