The randomized group will determine the order that a participant uses each device. Group 1 participants will use the wrist cooling device first for two weeks and then the fan activating device for two weeks. Group 2 participants will use the fan activating device first for two weeks followed by the wrist cooling device for two weeks.~This will be a 6 week study requiring the participants to see a study team member at the beginning of the study. The participants will receive three phone calls during the study to remind them of when to use each device. They will be instructed after the 6 weeks for them to have an in person return visit and give the diaries and the devices to the study personnel.
This pilot randomized double blind controlled crossover study aims to determine the impact of two wrist cooling devices on symptom control of hot flashes in adult men with prostate cancer and women with breast cancer experiencing hot flashes. The participants will record during the first two weeks of the study all of their hot flashes and severity of their hot flashes in a diary. The participants will be randomly assigned to wear one of the two wrist cooling devices that have an identical appearance at different times in the study. They will wear the first assigned device for weeks 3 and 4. They will record in their diary the severity of their hot flashes while using the device. For weeks 5 and 6 they will be ask to use a second device and record in their diary the severity of their hot flashes with the use of the device.~The devices will be attached to the wrist like a watch. When activated, one device will turn on a cooling fan with the cooling plate being active for up to 5 minutes, and the other device will turn on a cooling fan only for up to 5 minutes without the cooling plate being active.
