Miguel Martinez-Gonzalez, a scientist from Spain has studied over 13 thousand youth for over eight years and has reached conclusion that three hours of TV in a day could double the risk of early death compared to those who watch just one hour or less of TV.
“Television viewing is a major sedentary behavior and there is an increasing trend toward all types of sedentary behaviors. Our findings are consistent with a range of previous studies where time spent watching television was linked to mortality,” said Prof. Martinez.
“As the population ages, sedentary behaviors will become more prevalent, especially watching television, and this poses an additional burden on the increased health problems related to aging. Our findings suggest adults may consider increasing their physical activity, avoid long sedentary periods, and reduce television watching to no longer than one to two hours each day, explained Prof. Martinez, whose study is published in the Journal of The American Heart Association.
More TV means bigger waist sizes, higher cholesterol, more blood sugar and triglycerides. Added to the possibility of junk eating during these periods, this spells a tailored route for heart diseases. In the current society, adults spend 90% of their leisure time sitting, resulting in less than half of adults participating the recommended levels of physical work as per WHO standards.
Adults in UK watch about four hours of TV per day. In US, the number stands at over five hours. Those who watch TV more than six hours a day may lose five years of their life, says the study.
Other related studies say that young men who watch TV for just three hours a day face the risk of reduced sperm count by half compared to those who do not watch any TV.
