Too much television may cause early death
Washington: A new study has warned
that people who watch TV for three hours or more each day are likely to die
prematurely.
People should consider getting
regular exercise, avoiding long sedentary periods and reducing TV viewing to
one to two hours a day as suggested by researchers.
Around
13,284 young and healthy Spanish university graduates are assessed by the
researchers of the American Heart Association to determine the association
between three types of sedentary behaviour and risk of death from all causes:
television viewing time, computer accessing and driving time, Xinhua reported.
Researchers have found out that
there is no significant association between the time spent using a computer or
driving and higher risk of premature death from all causes.
They further says that studies are
needed to confirm what effects may exist between computer use and driving on
death rates, and to determine the biological mechanisms explaining these
associations.
Risk of
death is two-fold for those who reported watching three or more hours of TV a
day as compared to those watching one or less hours.

Thyroid treatment may prevent heart disease in
diabetics
New York: Low thyroid levels in the
cardiac tissue of diabetics may be the major cause of their associated heart
disease, a study has said, indicating that restoring thyroid hormones in heart
may prevent heart disease in diabetics.
Diabetes triggers low thyroid levels
that contribute to heart failure, the findings showed.
In animal
models, the researchers found that administering low doses of the active form
of thyroid hormone, T3, prevented the progression of heart disease.
"This treatment prevented the
abnormal changes in gene expression, tissue pathology, and heart
function," said Martin Gerdes from New York Institute of Technology in the
US.
The most recent study builds on a
growing body of research by Gerdes and others that link low thyroid hormone
levels in heart tissue to heart failure.
"The clinical implications are
profound and far-reaching because it suggests that the heart disease associated
with diabetes may be easily preventable," Gerdes added.
"And importantly, the dose we
gave of T3 hormone did not significantly change the serum (blood) thyroid
hormone levels but it was enough to make all the difference in the heart
tissue," Gerdes noted.
The study appeared online in the
journal Molecular Medicine.
