Middle-aged folks who regularly turn to TV for entertainment appear to have a greater risk of decline in their reasoning and memory later in life, three new studies suggest. Researchers found that even moderate amounts of TV viewing were associated with worse performance on cognitive tests as people aged.
Researchers say people who watch more television in middle age have a higher risk of declining brain health in later years. Their studies indicate that excessive TV watching can cause cognitive decline and a reduction in gray matter.
Another study from 2015 showed a strong tie between depression and binge TV watching–understandable, because screens are a tempting way to drown out negative thoughts and feelings. Distraction can only take you so far before you need to face your feelings.
While watching TV the frontal lobe becomes underdeveloped through disuse. With underdeveloped frontal lobe you also become less able to control your behavior and outburst of uncontrollable anger and lack of self-discipline are more likely to occur.
Examining the viewing habits of 599 American adults between 1990 and 2011, Dougherty found that those who watched an above average amount of television showed reduced volume in their frontal cortex and entorhinal cortex. Basically, your mum was right: TV really does rot your brain.
Longer TV viewing was associated with lower intelligence quotient (IQ) and reading grades in a cross-sectional study (Ridley-Johnson et al. 1983). However, the longitudinal effects of TV viewing on Full Scale IQ (FSIQ) are less clear (Gortmaker et al. 1990).
Good evidence suggests that screen viewing before age 18 months has lasting negative effects on children's language development, reading skills, and short term memory. It also contributes to problems with sleep and attention.
Life without TV cannot be better than a life with it. Not with 4K, UltraHD, Blu-Ray, On-Demand, Streaming, and everything else out there. Without TV, there'd be no daily hum of CNN, ESPN, Food Network, and the Today Show in our lives every day. But let me tell you, life without TV is better, so much better.
What's a healthy amount of screen time for adults? Experts say adults should limit screen time outside of work to less than two hours per day. Any time beyond that which you would typically spend on screens should instead be spent participating in physical activity.
Other studies have found negative effects including increased fatigue, mood disturbances, and insomnia. Many of these studies show correlation, rather than causation and it's easy to imagine that someone who is already depressed or anxious might spend more time binge-watching TV.
A study in Preventative Science Reports found elevated depression levels when people spent more time on computers and watching TV. In fact, those who spent more than four hours each day staring at a screen were about twice as likely to have depression.
Previous research has also linked prolonged television viewing to heart disease, blocked arteries and dangerous blood clots. In this new study, TV viewing increased the risk for life-threatening clots both in the arms and legs (a condition called deep vein thrombosis) and in the lungs (known as pulmonary embolism).
Physical damage to the brain and other parts of the central nervous system can also kill or disable neurons. - Blows to the brain, or the damage caused by a stroke, can kill neurons outright or slowly starve them of the oxygen and nutrients they need to survive.
Similar studies have found excessive TV watching to increase the risks of other chronic illnesses such as heart disease, Type 2 diabetes and pulmonary embolism. Of course, these studies evaluated long-term activity, collecting data over periods as long as 25 years.
Middle-aged folks who regularly turn to TV for entertainment appear to have a greater risk of decline in their reasoning and memory later in life, three new studies suggest. Researchers found that even moderate amounts of TV viewing were associated with worse performance on cognitive tests as people aged.
New research from the United Kingdom shows that regularly watching over three hours of TV each day could lead to cognitive decline in language and memory down the line. The study was published late February in the journal Scientific Reports.
Addicts use their addition to feel predictability, control, and to lessen tension. For example, being addicted to TV, which is a behavioral addiction, has been found to provide effects similar to other types of addictions. Different studies have argued for different amounts of time spent watching TV per day.
It's highly, highly unlikely that TV can create an anxiety disorder. There are a few exceptions - some people do develop fears and phobias because of television - but in general, you are likely to already have anxiety in some way and television simply makes it worse.
To sum it up, the answer is no. Watching movies or TV shows is definitely not a waste of time. But just like everything else that's good in this world, it must be enjoyed in moderation.
Television is an inescapable part of modern culture. We depend on TV for entertainment, news, education, culture, weather, sports—and even music, since the advent of music videos. With more and more ways of viewing TV available we now have access to a plethora of both good quality and inappropriate TV content.
A day without television means a life with better health and fitness, a day with more fun in outdoor activities. television is one of the most important inventions of science. watching television is not a bad habit,but it all depends on what we watch.
Early data from a landmark National Institutes of Health (NIH) study that began in 2018 indicates that children who spent more than two hours a day on screen-time activities scored lower on language and thinking tests, and some children with more than seven hours a day of screen time experienced thinning of the brain's ...
Too much screen time can lead to obesity, sleep problems, chronic neck and back problems, depression, anxiety and lower test scores in children. Children should limit screen time to 1 to 2 hours per day. Adults should also try to limit screen time outside of work hours.
According to research published Monday in the journal Pediatrics, watching fast-paced cartoons like SpongeBob, even for just a few minutes, hinders abstract thinking, short-term memory and impulse control in preschoolers.
