Non-Drug Treatment for Hot Flashes and Night Sweats in Patients with Cancer
Key Points for This Section
Treatments that change how patients deal with stress, anxiety, and negative emotions may help manage hot flashes. These are called psychological interventions. Psychological interventions help patients gain a sense of control and develop coping skills to manage symptoms. Staying calm and managing stress may lower levels of a hormone called serotonin that can trigger hot flashes.
Psychological interventions may help hot flashes and related problems when used together with drug treatment.
Hypnosis is a trance-like state that allows a person to be more aware, focused, and open to suggestion. Under hypnosis, the person can concentrate more clearly on a specific thought, feeling, or sensation without becoming distracted.
Hypnosis is a newer treatment for hot flashes that has been shown to be helpful. In hypnosis, a therapist helps the patient to deeply relax and focus on cooling thoughts. This may lower stress levels, balance body temperature, and calm the heart rate and breathing rate.
Comfort measures may be used to treat night sweats related to cancer. Since body temperature goes up before a hot flash, doing the following may control body temperature and help control symptoms:
- Wear loose-fitting clothes made of cotton.
- Use fans and open windows to keep air moving.
- Practice relaxation training and slow, deep breathing.
Studies of vitamin E for the relief of hot flashes show that it is only slightly better than a placebo (pill that has no effect). Most studies of soy and black cohosh show they are no better than a placebo in reducing hot flashes. Soy contains estrogen -like substances; the effect of soy on the risk of breast cancer growth or recurrence is not clear. Studies of ground flaxseed to treat hot flashes have shown mixed results.
Claims are made about several other plant-based and natural products as remedies for hot flashes. These include dong quai, milk thistle, red clover, licorice root extract, and chaste tree berry. Since little is known about how these products work or whether they affect the risk of breast cancer, women should be cautious about using them.
Pilot studies of acupuncture and randomized clinical trials that compare true acupuncture and sham (inactive) treatment have been done in patients with hot flashes. Results are not clear and more studies are needed. (See the Vasomotor symptoms section in the PDQ health professional summary on Acupuncture for more information.)
