Physical inactivity is a vicious circle. It's not just the quality of programming that holds you on the couch. According to a study that lasted 25 years, watching too much TV reduces willpower.

When we sit down to watch a show, it's common for us to watch the whole season.
The reasons may be the good plot or the performance of the characters.
But science has a good explanation.
Apparently a sedentary lifestyle steals willpower.
So says a study from the University of California at San Francisco (United States).
In it, 3,247 volunteers were followed over 25 years.
Every five years, participants responded about what they watched on TV daily.
And every two to five years, the volunteers answered about how much exercise they did.
After 25 years, participants were between 40 and 50 years old.
On this occasion everyone took tests that gauged their memory, focus and physical and mental agility.
As a result, those who practiced few exercises or watched at least three hours of television a day had the worst results on the focus and speed of thought tests.
It is already known about the health problems caused by lack of activity.
But brain damage is being evaluated only now.
If the TV blurs, no programs are saved?
We like to imagine that European documentaries or films make us smarter.
And it is certain that content with this profile stimulates cognition.
However, it is still uncertain to say that one programming is less harmful than the other.
Faced with the fact that it is indeed harmful.
The question is what happens to a person in his 50s, when changes, however small, have their consequences amplified.
In previous studies, it has been observed that exercise can protect the brain against Alzheimer's disease or dementia.
Maybe watching less TV can bring related benefits in later life.
Given this information, it is up to you to formulate your choices.

The study was published in the journal JAMA Psychiatry.
