Love your ‘to do’ list

Natural Health News — That “to do” list of chores, activities and errands can sometimes seem pretty onerous.

But new research shows that keeping busy actually provides a variety of health benefits, including a lower risk of early death.

According to researchers at the University of California San Diego School of Medicine. The study, published in the Journal of the American Geriatrics Society, found women over age 65 who engaged in regular light physical activity had a reduction in the risk of mortality.

“Every movement counts,” said Andrea LaCroix, PhD, senior author of the study and professor in the Department of Family Medicine and Public Health at University of California San Diego. “A lot of what we do on a daily basis is improving our health, such as walking to the mail box, strolling around the neighbourhood, folding clothes and straightening up the house. Activities like these account for more than 55% of how older individuals get their daily activity.”

Monitoring activity

The 6,000 women in the study, which was published in the Journal of the American Geriatrics Society, were aged 65 to 99, were followed for up to four and a half years.

They wore a measuring device called an accelerometer on their hip around-the-clock for seven days while going about their daily activities. The study found that 30 minutes of light physical activity per day lowered mortality risk by 12% while an additional 30 minutes of moderate activity, such as bicycling at a leisurely pace or brisk walking, exhibited a 39% lower risk.

“Improving levels of physical activity both light and moderate could be almost as effective as rigorous regular exercise at preventing a major chronic disease,” said LaCroix, chief of the Division of Epidemiology at UC San Diego School of Medicine. “We don’t have to be running marathons to stay healthy. The paradigm needs to shift when we think about being active.”

The study also found that the benefit of light physical activity extended to all subgroups of women examined. That means benefits were seen in women of different racial/ethnic backgrounds, obese and non-obese women, women with high and low functional ability and women both older and younger than age 80.

It all counts

“Older people expend more energy doing the same kinds of activities they did when younger, so their daily movement has to accommodate for this,” said LaCroix. “Think of it as taking a pill (activity level) at different doses (amounts of time) depending on the age of the patient. It’s not one size fits all.”

Current national public health guidelines recommend 150 minutes of moderate to vigorous physical activity a week for adults. The guidelines recommend persons 65 and older follow the adult guidelines to the degree their abilities and conditions allow.

“Our study shows, for the first time using device-measured light physical activity in older women, that there are health benefits at activity levels below the guideline recommendations. With the increasing baby boomer population in the United States, it is imperative that future health guidelines recommend light physical activity in addition to more strenuous activity,” said LaCroix.

“When we get up from the couch and chair and move around, we are making good choices and contributing to our health.”
