While it’s very comfortable to sit all day, there are several reasons you should change that.

Below are a dozen well-researched reasons why sitting all day is not healthy for you:

It hurts your heart

According to scientific research, those who sit for long hours are twice as likely to get heart disease compared to those who stand more.

It shortens your life span

You’re more likely to die earlier from any cause if you sit for long stretches at a time. It doesn’t help if you exercise every day or not.

Dementia is more likely

If you sit too much, your brain could look just like that of someone with dementia. Sitting also raises your risk of heart disease, diabetes, stroke, high blood pressure, and high cholesterol, which all play a role in the condition. Moving throughout the day can help even more than exercise to lower your risk of all these health problems.

You’ll undo all your exercise

The effects of too much sitting are hard to counter with exercise. Even if you work out 7 hours a week — far more than the suggested 2-3 hours — you can’t reverse the effects of sitting 7 hours at a time. Don’t throw away all that hard work at the gym by hitting the couch for the rest of the day. Keep moving!

The possibility of diabetes raise

It isn’t clear why, but doctors think sitting may change the way your body reacts to insulin, the hormone that helps it burn sugar and carbs for energy.

You could get DVT

Deep vein thrombosis (DVT) is a clot that forms in your leg, often because you sit still for too long. It can be serious if the clot breaks free and lodges in your lung. You might notice swelling and pain, but some people have no symptoms. That’s why it’s a good idea to break up long sitting sessions.

You will gain weight

Watch a lot of TV? Surf the web for hours on end? You’re more likely to be overweight or obese. If you exercise every day, that’s good, but it won’t make a huge dent in extra weight you gain as a result of too much screen time.

Your anxiety could spike

It could be that you’re often by yourself and engaged in a screen-based activity. If this disrupts your sleep, you can get even more anxious. Plus, too much alone time can make you withdraw from friends and loved ones, which is linked to social anxiety. Scientists are still trying to figure out the exact cause.

It wrecks your back

The seated position puts huge stress on your back muscles, neck, and spine. It’s even worse if you slouch. Look for an ergonomic chair that means it’ll be the right height and support your back in the proper spots. But remember: No matter how comfortable you get, your back still won’t like a long sitting session. Get up and move around for a minute or two every half hour to keep your spine in line.

It leads to varicose veins

Sit for too long and blood can pool in your legs. This puts added pressure in your veins. They could swell, twist, or bulge what doctors call varicose veins. You may also see spider veins, bundles of broken blood vessels nearby. They usually aren’t serious, but they can ache. Your doctor can tell you about treatment options if you need them.

Could lead to osteoporosis in older adults

Older adults who aren’t active may be more likely to get osteoporosis (weakened bones) and could slowly become unable to perform basic tasks of everyday life, like taking a bath or using the toilet. While moderate exercise won’t prevent it, you don’t have to go out and run a marathon or take up farming to stay mobile in your golden years. Just don’t plant yourself on the couch for hours at a time.

Increased risk of cancer

You may be more likely to get colon, endometrial, or lung cancer. The more you sit, the higher the odds. Older women have higher odds of breast cancer. That doesn’t change if you’re super-active. What matters is how much you sit.
