When the pandemic pushed millions of Americans to work from home, it was a gift to many. 

No commute, flexible hours, and the comfort of your own space. But years later, health experts are sounding the alarm on what that stillness is quietly doing to our bodies, and for many remote professionals, the stakes are especially high.

“Sitting is the new smoking” is no longer just a wellness buzzword. Researchers now link excessive sedentary behavior, defined by the National Institutes of Health as more than 9.5 hours of sitting per day, to cancer, cardiovascular disease, diabetes, obesity, and mental health decline. And like smoking, the damage accumulates silently, long before symptoms appear.

According to the Mayo Clinic research, sitting for extended periods slows circulation, lowers good cholesterol levels, and disrupts the body’s ability to regulate blood sugar, creating a perfect storm for chronic disease.

Dr. Karen Basen-Engquist, professor and deputy chair of Health Disparities Research at MD Anderson Cancer Center, explained the biological chain reaction in plain terms.

“When we are sitting too much, we are not burning the glucose from the food that we eat,” she said. “Insulin can start to rise to manage that glucose and can drive increases in certain growth factors that promote the growth of cancer.”

She added that prolonged sitting increases the risk of at least 13 different types of cancer, including colon cancer. For Black people who already carry an elevated risk for hypertension and diabetes, the compounding effect is significant.

“All of that is related to physical inactivity and sedentary behavior,” Basen-Engquist said, connecting excessive sitting directly to high blood pressure and the progression toward diabetes through chronically elevated insulin levels.

The musculoskeletal system also takes an early hit. Neck stiffness, back pain, wrist problems, and joint deterioration are among the first warning signs the body sends, signals that Sanford Health researchers describe as the body’s earliest distress calls from too much stillness.

Remote work made it worse

Before the uptick in remote work, office life built movement into the day by default: The walk to the parking lot, the stairs between floors, the lunch break off campus. That incidental activity is now gone for millions of workers, and health experts say that loss matters more than most people realize.

Felicia Sexton White, wellness manager at Legacy Community Health and a Houston-based fitness professional with over 20 years of experience, sees the consequences daily.

“Sitting for long periods of time not only makes you lazier, but it also affects the stiffness of the body,” she said. “Arthritis sets in, and then that rolls over to eating badly, and then that rolls over to ‘I just don’t feel like it.’”

White says remote workers often underestimate how deeply inactivity bleeds into their mental and emotional health. The overwork that comes with blurred work-life boundaries, she said, creates a dangerous cycle.

“You’re already in a stressful situation,” White said. “You don’t know how to turn the computer off at a decent hour, and once you get off, you don’t participate in outside activity because you feel like going nowhere. They get stuck in a rut.”

What you can do 

@postureguy

Sitting for extended periods causes the muscles at the front of your hips—your hip flexors—to become tight and shortened. At the same time, the glutes in the back grow weak and overstretched. This imbalance causes your pelvis to tilt forward into what’s called an anterior pelvic tilt, which throws off your posture and alignment from the ground up. One way to help reverse this is with the Air Bench exercise. 
Find a sturdy wall and wear shoes so your feet don’t slip. Walk your feet forward so your knees are at a 90° angle—or even a bit higher if that’s more comfortable. Keep your knees about a fist-width apart to prevent compensation. Tuck your pelvis under and flatten your lower back into the wall. Distribute your weight evenly into your heels, and press your lower back against the wall as if you’re pushing through your heels. Let your upper body relax, take deep breaths into your belly, and rest your hands on your thighs with your palms facing up. This strengthens postural muscles and helps reposition the pelvis into a more neutral, upright alignment. ✅ Want the full routine?

Basen-Engquist recommends that for every hour of sitting, get up and walk for at least two to three minutes. Public health guidelines also recommend 150 minutes of moderate physical activity per week, plus strength training twice a week, but she emphasizes that gradually building up is perfectly acceptable.

White also recommends walking pads for home use, free YouTube workout videos, water bottle resistance exercises, and even Legacy Community Health’s own free fitness videos available on their website.

“Know your body,” White said. “There is no job if you are not in your best physical, mental, or spiritual place. If you don’t do these things now, it will catch up with you later.”
