TV Indulger Should Watch Out For Heart Disease! After a day of hard work, most people would simply sit in front of the television (TV) sets in their houses watching favorite drama or movie as a way of relaxing. People in Europe and Australia spend about 40 percent (3 hours) and 50 percent (4 hours) respectively of their free time watching TV. United States has almost two-third of their people being overweight or even obese. They spend an average of about 5 hours, to as high as 8 hours, of their daily activity watching TV. TV watching is also a prevalent habit for people around the world. But do you know that watching long hours of television is bad for our health. In fact, a review of published studies in the past 40 years has shown that people who watch lots of TV had a higher risk of diabetes, heart disease and even early death. The findings were published by scientists from the Harvard School of Public Health in the June 15, 2011 issue of the ‘Journal of the American Medical Association’. The study indicated that people who spent more than 2 hours each day watching TV had increased risk of heart disease and Type-2 diabetes, and those who spent more than 3 hours had higher risk of dying prematurely. Moreover, every 2-hour increment in watching TV per day was linked to a 20 percent higher risk for Type-2 diabetes; a 15 percent increased risk for fatal or non-fatal cardiovascular disease; and a 13 percent higher risk for all-cause death.
In an earlier study, researchers from the Baker IDI Heart and Diabetes Institute in Victoria, Australia found that every hour spent watching TV each day boosted the risk of dying from heart disease by almost 20 percent, and couch potatoes were facing higher risk of death from other causes including cancer. Couch potato is a term used to describe a person who lives in a sedentary lifestyle, which include sitting, reading, watching TV and computer use for much of the day with little or no vigorous physical exercise. According to the findings, which were published on January 11, 2010 in ‘Circulation’ (the Journal of the American Heart Association), people who spent hours watching TV significantly increased the likelihood of dying early from heart attack and stroke. Comparing to those watching less than 2 hours of TV, people who sat in front of television sets for more than 4 hours a day were 80 percent more likely to die from heart disease and artery disease. A total of 3,846 men and 4,954 women aged 25 and above, who underwent sugar tolerance tests and provided blood samples, were interviewed. These participants were recruited from 1999 and studied for the next 6 years. They were grouped according to whether they watched less than 2 hours a day, between 2 and 4 hours, or more than 4 hours. It was found that during the follow-up period, there were 284 deaths, 87 from cardiovascular, or heart and artery disease, and 125 from cancer. The link between cancer and watching TV was modest, but the link between watching TV and a higher risk of cardiovascular death was strong, even after taking into account of recognized heart disease risk factors like raised cholesterol levels and lifestyle. Because of technological, social and economic changes, it is sad that people do not move their muscles as much as they used to. Many normal activities involving standing up and moving the muscles in the body have been converted to sitting. Majority of people simply shift from one chair in the office to another chair in front of their TV at home. In addition to doing regular exercise, people should avoid sitting for long period of time. Too much sitting is bad for the health. Remember this, the risk of getting heart disease, Type-2 diabetes and premature death can greatly be reduced if they can cut down the hours of watching TV.
