Watching TV for a long time increases the risk of dementia University of Arizona researchers looked at data from 145,000 people aged 60+ and concluded that spending too much time in front of the TV or other forms of inactivity increase the risk of developing dementia.

During the study of this issue, the experts used questionnaires on the touch screen, where participants themselves notified about the level of activity during the survey period.. Then, after 12 years of follow-up, they used patients' hospital records to find out who had been diagnosed with dementia.. It turned out that it was fixed 3507 times.

The researchers then took into account different demographics (age, gender, race/ethnicity, type of employment) and lifestyles (presence/absence of bad habits, exercise, alcohol and social contacts, and sleep patterns) because they influence the condition.

After analyzing the entire array of data, scientists came to the conclusion that the risk of dementia is not related to the time spent sitting, but the type of activity.. So, if a person was physically active, but devoted time to TV, he had an increased risk of developing the disease.. But people sitting at the computer - reduced risk.

This is due to the fact that watching television does not require a person and is essentially a passive pastime.. But if a person, for example, writes an email or plays video games that require effort, then he uses more cognitive functions.. At the same time, experts emphasize that, regardless of the nature of pastime, a sedentary lifestyle still has a bad effect on health..
