Tired of Hot Flashes? Here’s What You Can Do About Them
80% of women will experience hot flashes, flushing, and night sweats as they transition through the menopausal years. The medical community refers to these symptoms as vasomotor symptoms or VMS. The hypothalamus triggers hot flashes and night sweats in the brain to release heat built up in the body in response to a surge of adrenaline, one of our stress hormones. While the sudden drop in estrogen is thought to be the primary trigger of the cascade that causes a hot flash, high cortisol, low cortisol, low progesterone, or low serotonin can also be drivers for hot flashes.
On average, hot flashes and night sweats last 7.4 years and can begin five years before the onset of menopause. Recent research suggests that the severity of hot flashes and night sweats (rather than frequency) is associated with an increased risk of cardiovascular disease.[1]
What can we do to reduce hot flashes and night sweats?
Nutrition and lifestyle
Reduce/avoid alcohol (especially red wine) which can, in some women, exacerbate symptoms
Reduce/avoid caffeine which can, in some women, exacerbate symptoms
Increase whole foods and reduce processed foods
Incorporate more phytoestrogens into your diet - foods that contain plant estrogens. These agents are similar in structure to our endogenous (internally made) estrogen, which means they can bind to estrogen receptors and help reduce erratic fluctuations in estrogen
Consider ground flaxseeds (2 TBSP) into your daily routine for added fiber and phytoestrogen benefits.
Consider whole, organic (non-GMO) soy foods like miso, tempeh, tofu, soy milk, and edamame (young soybeans in the pod).[2] Much of the soy in the U.S. is genetically modified and heavily processed; it’s best to avoid soy protein isolate and concentrate, genetically engineered soy foods and soy junk foods like soy cheese, soy ice cream, soy oil, and soy burgers.
Incorporate exercise into your daily routine, especially resistance training and high-intensity interval training (HIIT).
In one study, resistance training performed three times per week decreased the frequency of moderate and severe hot flashes.[3]
Acupuncture may help relieve hot flashes and night sweats[4], [5],
Supplements and herbs
Maca root is a cruciferous vegetable that may increase estrogen and modulate all of your hormones.
Estrovera contains rhubarb, which has been shown to reduce hot flashes.
Bee pollen extract tends to help more with hot flashes present with sleep disturbances.[6]
Sage (Salvia officinalis) may reduce hot flashes, sleep disturbances, and night sweats[7], [8]
Hypericum perforatum (St. John's Wort) 270-330 mg three times per day has been shown to improve both hot flashes and depression scores in menopausal women.[9] **Warning: Women on antidepressants should always consult with their physician before taking St. John’s Wort.
Black cohosh (40-80 mg per day), when combined with St. John’s Wort (300 mg three times per day), has been shown to improve some low estrogen symptoms, including hot flashes.[10], [11] (Older studies suggest that black cohosh may have an estrogenic effect on the body, but newer research suggests that it may act on serotonin receptors instead, which can be helpful for hot flashes and mood improvement).
Valerian (530 mg capsules twice per day) has been shown to reduce severity and frequency of hot flashes in some women.[12]
Medications
Gabapentin is an FDA-approved prescription medication for neurological conditions but has also been shown to help relieve hot flashes and night sweats (estrogen replacement is more effective in reducing hot flash frequency than gabapentin).[13]
SSRIs or selective serotonin reuptake inhibitors, commonly used to treat depression, have been shown to reduce vasomotor symptoms. As of today, Paroxetine is the only FDA-approved nonhormonal SSRI for reducing VMS, but other SSRIs have been used “off-label” with some success as well.[14]
Hormone replacement therapy
Estrogen replacement therapy remains the most effective treatment for relieving vasomotor symptoms. Most women can expect to experience a reduction in hot flash frequency and intensity within 6-8 weeks after initiating HRT.
Estriol alone may reduce hot flashes in some women.
Warning: As always, be sure to check with your physician or licensed health care practitioner before trying any new supplements.
