I was told that doing household activities at a moderate intensity may lower my risk for breast cancer. What exactly does this include?

A long-term study spanning a woman's natural lifetime was recently reported. The researchers said that women who do household activities at a moderate level may lower their risk of breast cancer. "Moderate intensity" refers to getting the heart rate up and breaking a sweat.

Unfortunately, the researchers did not specify exact activities. The women in the study reported their activities, and each activity was rated according to how hard it was. If you follow the same guidelines with your household activities (increase your heart rate and break a sweat), then you should get the same benefit as the women in the study.
