Sitting too much harms your health.

The Dangers of Sitting All Day: 7 Health Risks You Need to Know

Since 1950, the rate of sedentary jobs—those that require prolonged periods of sitting—has increased by 83 percent, according to the American Heart Association. Add in the internet and streaming services, and it’s easy to see how some people end up sitting from morning to night.

This increase in sedentary lifestyle has taken a profound toll on our health, says the World Health Organization (WHO). Their experts estimate that physical inactivity contributes to two million deaths per year, making it one of the top 10 leading causes of death and disability in the world.

1. Weight Gain

Sitting for long periods of time can lead to weight gain, as it slows down your metabolism and reduces the number of calories you burn. A 2012 study published in the Texas Heart Institute Journal illustrates just how closely obesity and a sedentary lifestyle are linked.

2. Chronic Pain

Sitting for extended periods can lead to poor posture and back pain, particularly if you’re not sitting in an ergonomic chair or if you’re slouching. The spine was designed for elongation, and when you sit on a couch, bed, or other soft surface for prolonged periods, the spinal vertebrae become compressed.

3. Cardiovascular Disease

Research shows that when you sit all day, your risk of cardiovascular disease increases—even if you work out. Sitting for long periods can lead to higher levels of cholesterol and triglycerides in the blood.

4. Diabetes

Sitting for too long can increase your risk of developing Type 2 diabetes, as it can lead to insulin resistance.

5. Mental Health

Those who lead a sedentary lifestyle tend to experience increased levels of stress, anxiety, and depression. A 2020 study published in the Journal of Environmental Research and Public Health looked at how levels of depression coincided with increased rates of sitting during COVID-19 lockdowns.

6. Prostatitis

Prolonged periods of sitting can harm the scrotum and prostate gland, leading to inflammation of the prostate.

7. Poor Circulation

Sitting all day can hurt your circulation, particularly if you have your knees bent while sitting on a chair. Poor circulation can lead to cells not getting enough oxygen, which can impact their function.

The good news is that taking breaks from long periods of sitting can profoundly improve your musculoskeletal health and comfort. Experts recommend that you stand, stretch, and walk every half hour for at least a minute or two.

Remember, if you have health questions or concerns, always consult your healthcare provider directly.
