Hot flashes are sudden feelings of warmth, which are usually most intense over the face, neck and chest. Hot flashes can also cause sweating. Because of losing too much body heat, you might feel chilled afterward. Hot flashes can vary greatly in frequency and intensity. How long symptoms last varies significantly. On average, symptoms persist for more than seven years. Some women have them for more than 10 years. Hormone replacement is most frequently used treatemnet. There are the pros and cons of the treatment. If hot flashes don't interfere with your life, you probably don't need treatment. Hot flashes subside gradually for most women, even without treatment, but it can take several years for them to stop. Nonpharmacological methods are used for hot flashes. Acupuncture is one of them. A research analysed three published trials of nonpharmacological interventions for menopausal hot flashes to compare the effectiveness of interventions. Data from three randomized controlled trials of interventions for hot flashes (two acupuncture trials, one yoga trial) were pooled. All three studies recruited perimenopausal or postmenopausal women experiencing ≥4 hot flashes/d on average. The primary outcome for all three studies was frequency of hot flashes as measured by the Daily Diary of Hot Flashes. Study 1 participants were randomly assigned to 8 weeks of acupuncture treatments (active intervention), sham acupuncture (attention control), or usual care. Study 2 participants were randomly assigned to 10 weeks of yoga classes, health and wellness education classes (attention control), or waitlist control. Study 3 randomly assigned participants to 6 months of acupuncture or waitlist control. To standardize the time frame for these analyses, only the first 8 weeks of intervention from all three studies were used. There results have shown that the three active interventions and the two attention control groups had statistically similar trends in the percentage reduction of hot flashes over 8 weeks, ranging from 35% to 40%. Acupuncture, yoga, and health and wellness education classes all demonstrated statistically similar effectiveness in reduction of hot flash frequency compared with controls.
