Sedentary Lifestyle Health Risks | Sedentary Lifestyle Effects
April 13, 2017
First, you may be wondering what we are referring to when we mention a sedentary lifestyle. A sedentary lifestyle is defined as a type of lifestyle where an individual does not receive regular amounts of physical activity.
Where physical inactivity is considered the failure to meet the recommendations of the Center for Disease Control (CDC), stating that an individual should participate in a minimum of 150 minutes of moderate exercise, or 75 minutes of a more vigorous regimen.
Most health professionals are also in agreement that walking 10,000 steps a day (approximately 5 miles) is the ideal goal to set for improving health and reducing the health risks caused by inactivity.
According to the World Health Organization (WHO), 60 to 85% of the population worldwide does not engage in enough activity. Making physical inactivity the fourth leading risk factor for global mortality.
Traditional thought suggests that having a healthy diet and getting aerobic exercise will offset the effects of time spent being sedentary.
Even if you exercise for 30 minutes a day, you may not be able to counteract the effects brought on by a lack of activity throughout the rest of your day.
Rather, the solution seems to be less sitting and more moving overall, says Levine. Again, we suggest aiming for 10,000 steps a day.
Sedentary Lifestyle Health Effects
In 2005, James A. Levine, an obesity specialist at Mayo Clinic, pioneered the way for research on the negative effects of a sedentary lifestyle by publishing an article in Science Magazine. Levine’s conclusion was that Any extended sitting – such as behind a desk at work or behind a wheel – can be harmful.
Levine has even gone as far as labeling sitting as the disease of our time. Now I’m sure it’s no surprise that sitting behind a desk, commuting or relaxing on the couch for too many hours a day can be harmful to your health, but what you may find surprising is the extent of havoc it is causing on your body.
According to an article posted by John Hopkins Medicine, physical inactivity has been shown to contribute to the following health conditions:
- Physical inactivity may increase the risks of certain cancers.
- Physical inactivity may contribute to anxiety and depression.
- Physical inactivity has been shown to be a risk factor for certain cardiovascular diseases.
- People who engage in more physical activity are less ly to develop coronary heart disease.
- People who are more active are less ly to be overweight or obese.
- Sitting too much may cause a decrease in skeletal muscle mass.
- Physical inactivity is linked to high blood pressure and elevated cholesterol levels.
Worldwide, it is estimated that a sedentary lifestyle is responsible for 6% of coronary heart disease cases, 7% of type 2 diabetes, 10% of breast cancer and 10% of colon cancer cases. In fact, it was recently reported that inactivity is responsible for more annual deaths than smoking.
So why is it that we are more sedentary now than we were just 50 years ago? The main contributing factor to our increased sedentary lifestyles is technology. Technology has brought about more inactive modes of transit, caused an increase in sedentary desk jobs and has developed more activities that can be done while sitting (i.
e. watching TV, surfing the web, playing video games). Overall, sedentary jobs have increased 83% since 1950 and physically active jobs now make up only about 25% of our workforce, which is 50% less than in 1950. Additionally, our average work week is longer. Americans now work 47 hours a week–164 more hours a year than 20 years ago.
The good news is that this doesn’t have to be your fate. Though the general workplace movement is heading toward a more sedentary setting as machines continue to replace jobs in which require more activity, you don’t have to. The easiest way to increase activity levels is doing so at the workplace, a place in which the average individual spends up to eight or more hours sitting.
Simply by swapping out your chair for a treadmill desk or bike desk a few hours a day, you can significantly reduce the effects caused by inactivity. Within two weeks, people basically get addicted to walking and working, says Levine. You just have to give them the chance.
COVID-19: Infection Control in Your Home – COVID-19 – Johns Hopkins Bloomberg School of Public Health
If someone in your home is sick—whether confirmed or suspected to be COVID-19—that doesn’t mean all members of the household will get sick. There are still things that everyone in a home can do that may help reduce risk of transmission.
Anna C. Sick-Samuels and Raphael P. Viscidi, from the Johns Hopkins University School of Medicine offered some guidance on the most important things to do—and how the equation changes if one of your family members is in a high-risk category.
Risk-Reducing Behavior Matters
Most often, the virus will spread through very close contacts with people who are sick with symptoms or from touching your face or mouth with contaminated hands. So, risk-reducing behaviors are the most important priority.
That means encouraging more rigorous and frequent handwashing—especially when entering or leaving the house and after using the bathroom; avoiding touching faces; coughing or sneezing into our elbows; and throwing away used tissues.
Spring Cleaning Could Save Lives
Regardless of whether or not anyone in the household is sick, everyone should be stepping up hygiene. It’s also a good idea to disinfect frequently touched surfaces door knobs and light switches.
A CDC how-to guide gives tips on how to clean everything from carpets to laundry, what solutions to use, and specific precautions to take. If someone in the house is sick, give them a separate, lined trash can if possible, and use gloves or wash hands after handling the trash.
Increasing ventilation by opening windows and adjusting air conditioning could help, too.
A Little Distance Could Keep You Healthy
People should try to keep some physical distance—ideally 6 feet apart—between a sick person and other household members, when feasible.
If it’s possible to relocate a high-risk or sick person to a separate room or even another home, that could help. But that isn’t practical or possible for everyone.
If you don’t live in a mansion—or can’t give someone their own room and bathroom—don’t despair. What’s really important are the behaviors.
Remember, too, that if one member is in a high-risk category (e.g. older people and those with significant underlying conditions), that calls for heightened vigilance.
Healthy household members should behave as though they pose a significant risk to more vulnerable members even before anyone is sick, according to a CDC guide with infection control strategies tailored to a variety of settings and situations.

The High Cost of Inactivity
There was a time long ago when the leading causes of death were due to non-preventable factors age and gender.
Sadly, we now live in a time when children and adults, and men and women a are developing chronic diseases caused by preventable risk factors such as poor diet and sedentary lifestyles.
As a matter of fact, physical inactivity is now the fourth leading risk factor for global mortality[i].
As a nation, we spend far more time sitting on the couch and scrolling through our Instagram feed than we do moving our bodies. All of this sedentary living is costing us dearly, not only wreaking havoc on our physical health, but also robbing us of our emotional wellbeing and hitting us where it hurts the most—our wallets. Here’s a look at the price we pay for inactivity:
Quality of Life
Regular physical activity can boost mood and decrease anxiety, depression and anger[ii]. In fact, many therapists recommend regular physical activity as part of a treatment plan to combat the effects of depression.
The amount of sitting we do can lead to daily discomforts chronic back pain and has even been shown to knock years off of our lifespan[iii]. Furthermore, objects in motion tend to stay in motion.
If you’re regularly moving your body, it’s easier to continue moving and to say yes to all that an active lifestyle has to offer—social activities, hiking, running, dancing, biking, etc.
Only 55 percent of adults engage in enough physical activity to achieve its health benefits, and that number is even lower for children, with only 25 percent meeting activity guidelines[iv].
Sedentary lifestyles can lead to a decrease in bone density and lean muscle mass; tightened hip muscles; and an overall loss in muscle strength, making even small daily tasks more difficult[v]—and that’s just the minor stuff.
Lack of regular physical activity also increases the risk of obesity, heart disease, stroke, type 2 diabetes and some cancers[vi].
Physical inactivity accounts for roughly 8.7 percent of U.S. health care expenditures, or approximately $117 billion per year. Adults who are physically active spend nearly $1,500 less per year on health care than inactive adults[vii]. Moving our culture from sedentary to active could save us billions of dollars in health care costs in the years to come.
Physical inactivity is an equal opportunity issue, affecting all Americans regardless of race, age or gender, directly or indirectly. If you’re wondering, “Where is the silver lining?” we’ve got good news—the inactivity crisis is entirely preventable.
Each and every one of us can make positive changes to get ourselves and others moving. Start with small actions, committing to more outdoor, active family time; using your voice to vote for candidates that support physical activity; or incorporating walking and standing into your work day.
Most importantly, we all need to adopt the attitude that small actions can cause big change.

Teens get as much physical activity as 60-year-olds, study shows
Lack of physical activity is a risk factor for many serious conditions. The fact that neither adults nor teenagers get as much exercise as they should is, perhaps, not very surprising. But new research shows that the situation might be a lot more worrying than previously believed.
Share on PinterestTeenagers get as much physical exercise as seniors, according to a new study.
The Centers for Disease Control and Prevention (CDC) recommend that adults engage in at least 2.5 hours of physical activity per week.
The CDC also report that only 1 in 5 adults gets this much physical activity. People who do not get the exercise they need are more ly to die prematurely or develop a range of serious illnesses such as heart disease, stroke, type 2 diabetes, depression, and some forms of cancer.
Not only do adults not get enough exercise, but teenagers fare even worse. Fewer than 3 in 10 high school students get a minimum of 60 minutes of daily physical activity, which is the level of exercise recommended by both the CDC and the World Health Organization (WHO).
New research, published in the journal Preventive Medicine, suggests that the situation might be even more grim than previously thought; levels of physical activity among teenagers are surprisingly low, the study finds.
The team of researchers from the Johns Hopkins Bloomberg School of Public Health in Baltimore, MD, set out to examine levels of physical activity across several age groups. Additionally, the research looked at different times of the day and their corresponding levels of activity, as well as differences in exercise patterns according to gender.
The study’s senior author was Vadim Zipunnikov, an assistant professor in the Bloomberg School’s Department of Biostatistics.
Prof. Zipunnikov and colleagues examined a total of 12,529 participants, accessing the data available from the National Health and Nutrition Examination Surveys carried out in 2003-2004 and 2005-2006.
The participants continuously wore tracking devices for 7 consecutive days, taking them off only when they went to bed or had a shower.
These devices tracked how long the participants were sedentary for, and for how long they engaged in light or moderate-to-vigorous physical activity.
The scientists divided the participants into five groups according to age: children (aged between 6 and 11), adolescents (12 to 19 years old), young adults (aged between 20 and 29), midlife adults (31 to 59 years old), and older adults (aged between 60 and 84).
In terms of gender, 49 percent of the participants were male, and 51 percent were female.
Overall, males tended to be more physically active than females, particularly excelling at high-intensity activity.
After midlife, however, physical activity levels in males plummeted, compared with females. In the group aged 60 years and above, males were considerably less physically active, more sedentary, and engaged in less light-intensity physical activity than females.
Researchers found a spike in physical activity levels in only one age group: the 20-something-year-old adults. People in this group tended to be more active in the early morning.
Surprisingly, the study found that teenagers were at the highest risk of being physically inactive, and in their late teens, this group was ly to get as little exercise as seniors.
The study is particularly significant given the high childhood obesity rates in the United States. The CDC report that approximately 12.7 million U.S. children and teenagers are obese.
“Activity levels at the end of adolescence were alarmingly low, and by age 19, they were comparable to 60-year-olds. For school-age children, the primary window for activity was the afternoon between 2 and 6 p.m. So the big question is how do we modify daily schedules, in schools for example, to be more conducive to increasing physical activity?”
Prof. Vadim Zipunnikov
Furthermore, the study confirmed that children and teenagers do not meet the WHO’s guidelines for physical activity.
“The goal of campaigns aimed at increasing physical activity has focused on increasing higher-intensity exercise,” explains Prof. Zipunnikov. “Our study suggests that these efforts should consider time of day and also focus on increasing lower-intensity physical activity and reducing inactivity.”

Wearable Activity Trackers a Reliable Tool for Predicting Death Risk in Older Adults
Newswise — A federally funded study by Johns Hopkins Medicine researchers shows that wearable accelerometers — mechanical sensors worn a watch, belt or bracelet to track movement — are a more reliable measure of physical activity and better than patient surveys and other methods used by physicians at assessing five-year risk of death in older adults.
The research also added to evidence that an accurate and objective accounting of physical activity outperforms traditional predictors of mortality within five years, such as age, smoking, diabetes, alcohol use, or history of cancer or heart disease.
these findings, the researchers say physicians could confidently use the devices’ fitness profiles to help patients change unhealthy behaviors, increase physical activity and, potentially, extend healthy lifespans.
While their study is far from the first to report an association between physical activity and risk of death, the investigators say their findings, reported in the Oct. 15 issue of The Journal of Gerontology: Medical Sciences, is among the first to offer solid evidence that wearable activity trackers provide key predictors of mortality that outperform other measures.
“People can overestimate or underestimate on surveys how much and when they move, but wearable devices provide accurate data that cuts through the bias and guesswork,” says Jacek Urbanek, Ph.D.
, assistant professor of medicine at the Johns Hopkins University School of Medicine and a member of the research team.
“The technology is readily available and relatively inexpensive, so it seems feasible to be able to incorporate recommendations for its use into a physician’s practice.”
“We’ve been interested in studying physical activity and how accumulating it in spurts throughout the day could predict mortality because activity is a factor that can be changed, un age or genetics,” says Ciprian Crainiceanu, Ph.D., professor of biostatistics at the Johns Hopkins Bloomberg School of Public Health, who is also a member of the research team.
For the new study, the researchers focused on the total amount of physical activity and times the participants were most active during the day.
First, using data from the National Health and Nutrition Examination Survey (NHANES) conducted by the U.S.
Centers for Disease Control and Prevention (CDC), researchers looked at 33 predictors of five-year all-cause mortality, including 20 objective measures of physical activity, such as total activity, amount of time not moving or amount of time doing moderate to vigorous activity.
In this way, they ranked physical activity and other factors, such as total cholesterol, smoking status, and having cancer or diabetes, to identify which ones best predict mortality within the following five years of the study population.
For their look at physical activity, the researchers used accelerometry data from nearly 3,000 adult Americans collected during the NHANES 2003–2004 and NHANES 2005–2006 surveys.
Individual data came from responses to demographic, socioeconomic and health-related survey questions, along with information accessed from medical records and clinical laboratory test results.
Participants were asked to wear an accelerometer device at the hip for seven consecutive days, removing it only when sleeping, showering or swimming.
The average age the study group was 65.9, and all participants were between 50 and 84 years old. While the gender proportion was nearly even — men made up 51% — a larger percentage of the men, 65%, died within five years of the study’s follow up efforts.
After studying each individual variable associated with mortality — including education, sedentary time, and ethnicity — the researchers concluded that the total measure of physical activity accumulated during each day was the strongest predictor of five-year mortality, followed by age and moderate-to-vigorous activity.
When comparing the data of a person who died within five years and a person who survived, researchers said they were able to correctly rank the mortality risk using accelerometers 30% more accurately than using information about smoking status and 40% better than using information about whether a person suffered a stroke or had cancer.
With a focus on fragmented activity, researchers also collected data for two-hour spans throughout the day in order to look at patterns in physical activities.
Their analysis showed that physical activity — or lack thereof — between noon and 2 p.m.
was the highest predictor of mortality risk, outperforming more commonly considered risk factors such as diabetes, cancer and alcohol consumption.
The researchers caution that their study wasn’t designed to establish cause and effect, however, they did note that their data suggests that being more sedentary during the day is linked with higher mortality.
“The most surprising finding was that a simple summary of measures of activity derived from a hip-worn accelerometer over a week outperformed well-established mortality risk factors such as age, cancer, diabetes and smoking,” says Ekaterina Smirnova, M.S., Ph.D., assistant professor of biostatistics at Virginia Commonwealth University and the lead author on the paper.
“While this study affirmed a link between physical activity and short-term mortality risk in an older population, the data don’t guarantee that one’s risk of mortality is going to be lower with more physical activity,” noted Andrew Leroux, a Ph.D.
candidate at Johns Hopkins and co-author of the study report.
“However, our findings do indicate that an accurate measure of physical activity is a more reliable way for doctors and patients to assess physical activity and intervene to increase it as a potential way to improve health.”
The researchers hope to use their data to help design clinical trials that could confirm the potential for physical activity to increase lifespan. One caveat to the study is that researchers aren’t able to distinguish sedentary behavior from sleep or if someone has removed the device.
