While strolling or running are beneficial for heart health, light physical activity, such as gardening and folding clothes, may also lower the risk of cardiovascular diseases (CVD) in older women, say researchers.
The association was strong across all racial and ethnic groups, noted the study published in the journal JAMA Network Open.
"And the risk reduction showed regardless of the women's overall health status, functional ability or even age. In other words, the association with light physical activity was apparent regardless of these other factors," LaCroix added.
For the study, researchers studied nearly 6,000 women aged 63 to 97. They were made to wear a device which measured their movement 24 hours a day for seven consecutive days. The device was also calibrated by age to distinguish between light, and moderate-to-vigorous physical activity.
Most people do not think of folding clothes or walking to the mailbox as physical activity of any kind, the researchers said.
