Heart risks increase if sitting long hours before TV!!

That sitting for long periods of time  is linked to increased risk of cardiovascular diseases and early death is  a fact known to many. The sedentary life has become part of modern life and at offices and banks, employees work 8 to 10 hrs minimum daily and much time is spent before the computer. At home  non-working Indian women folks sit before the TV and watch the tear-jerking soap operas  at noon and get carried away when they see cliff-hangers late in the evening in which elderly family women have become vicious vigilantes.

Increasing number of research works on sedentary life and cardiac conditions point out that those who are sedentary -- especially those who sit for long, uninterrupted periods of time -- have a higher risk of cardiovascular disease and death. Since the sedentary habits vary among people, correct conclusion is difficult to make. African Americans, Europeans and Asians have different sedentary habits  and you can not draw a line with respect to risk factors  as the cardiac conditions of certain ethnic groups vis-a-vis sedentary habits may not show the same results.

Good news for the folks, a  new study suggests the possibility   that not all types of sitting are equally unhealthy.

The study, led by the researchers at Columbia University Vagelos College of Physicians and Surgeons conducted a detailed study on more than 3,500 participants to find out the link between  leisure-time sitting (while watching TV;  not sitting at work) and the  risk of heart disease and death. The study concluded that moderate-to-vigorous exercise will help people   reduce or eliminate the harmful effects of sedentary television watching.

Based on a new study of roughly 3550 plus African Americans in Jackson, MS who watched TV 2 to 4 hrs daily, it was concluded that  those who watched  the most TV-viewing hours (4 or more hours a day) had a 50% greater risk of cardiovascular events and death compared to those who watched the least amount of TV (less than 2 hours a day).  In contrast, those who sat the most at work had the same health risks as those who sat the least.

Moderate to vigorous physical activity -such as  brisk walking  or aerobic exercises will reduce  the risk of heart attacks, stroke, or death in the case people who are glued to TV for a long time. .  However, the study found no higher  risk of heart attack, stroke, or death was seen in those who  sat before TV  for 4 or more hours a day and engaged in 150 minutes or more of exercise a week.

According research author to Keith M. Diaz, PhD, assistant professor of behavioral medicine at Columbia University  and  a certified exercise physiologist,  "Our findings show that how you spend your time outside of work may matter more when it comes to heart health. He says if you have long-hour sedentary job, if you have  strenuous  exercise  schedule, this could reduce  cardiac risks. In an early  study, Diaz found that excessive sitting is linked to worse health problems and even more so when sitting occurs in lengthy, uninterrupted bouts. Source: Columbia University Irving Medical Center; Date June 26, 2019)
