1-It Hurts Your Heart<br />Scientists first noticed something was up in a study that compared two similar groups: transit drivers, who sit most of the day, and conductors who don’t. Though their diets and lifestyles were a lot alike, those that first group were about twice as likely to get heart disease as those that second group .<br />2- It Can Shorten Your Life<br />You’re more likely to die earlier from any cause if you sit for long time. It doesn’t help if you exercise every day or not.<br />3-Dementia Is More Likely<br />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.<br /> <br /><br />4-Your risk of Diabetes Rise<br />Yup, you’re more likely to have it, too, if you sit all day. And it isn’t only because you burn fewer calories. It’s the actual sitting that seems to do it. 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.<br /> <br /><br />5-You Could Get DVT<br />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.<br /> <br /><br />7-You’ll Gain Weight<br />Watch a lot of TV? You’re more likely to be overweight or obese.<br />8-Your Anxiety Might Spike<br />t 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.<br />9-It Wrecks Your Back<br />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. <br /> <br /><br />10-It Leads to Varicose Veins<br />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. They usually aren’t serious, but they can ache. Your doctor can tell you about treatment options if you need them.<br /> <br /><br />11-If You Don’t Move It, You Could Lose It<br />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. <br />12-Your Cancer Risk Goes Up<br />You may be more likely to get colon, endometrial, or lung cancer. The more you sit, the higher rate . Older women have higher rate of breast cancer. <br /><br />By: Dr. Mokhlis Turki
