Too Much Sitting: A Risk for Heart Attack?

0 comments / Posted on by Daniel Tahany

Do you sit at work most of the time? Do you spend your free time surfing the net, watching TV, or reading? How much time do you dedicate for recreational physical activities?

These questions are important because too much sitting can increase a person’s risk for heart attack, says a study published by International Journal of Behavioral Nutrition and Physical Activity. In fact, the more time you spend with your chair or couch, the greater your risk for having a heart attack. Having less physical activity during off-hours and sitting for more than 10 hours daily increases your chance of developing coronary heart disease, a potentially lethal health condition caused by build-up of cholesterol deposits and inflammation within the major blood vessels of the heart.

Blood flow and oxygen supply to your heart muscles decrease when cholesterol deposits build up within your heart’s blood vessel walls.  Decreased blood flow to your heart can cause chest pain and shortness of breath. Cardiac arrest occurs when too much cholesterol blocks your artery clogs.

Coronary heart disease is the most common cause of death in the adult American population. According to the Centers for Disease Control and Prevention, approximately 600,000 men and women die of heart disease in the United States; and another 720,000 Americans suffer from heart attack every single year.

Myocardial infarction – commonly known as a heart attack – is the irreversible damage to the heart muscles caused by lack of oxygen supply. The most common signs and symptoms of an impending heart attack include chest pain or discomfort, shortness of breath, cold sweats, lightheadedness and discomfort in the arms, neck, jaw, back or upper stomach.

Lack of regular physical activity causes 250,000 deaths in the American population every single year. In fact, sedentary lifestyle is now considered as one of the five major risk factors for the development of heart diseases according to Circulation, the journal of the American Heart Association.

To prevent the development of heart diseases, you must have an active lifestyle. Don’t sit too much for too long when working. Move around. Spend less time watching your favorite television and Netflix shows. Have regular exercise. Thirty minutes of modest physical activity every single day is not enough; you must keep yourself active. Push it to the limit!
