Frequent Google searches, and more unexpected things make us … less smart.Let’s Discuss 7 daily habits that reduce our intelligence.
1. Saturated fats reduce cognitive flexibility
Foods high in fat r high in sugar impair cognitive flexibility, found a new study.
Cognitive flexibility is the ability to adapt and respond adequately to changing situations.
The study was performed on laboratory mice. They are placed on a normal diet, a high-fat diet and a high-sugar diet.
After four weeks, the mental and physical abilities of mice eating more fat and more sugar began to decline.
2. Multimedia multitasking shrinks the brain
Using laptops, phones and other media devices at the same time can shrink important structures in the brain, points to another research.
For the first time, neurobiologists have found that people who use multiple devices simultaneously have a lower density of gray matter in the area of the brain that binds in cognitive and emotional control.
Multitasking can include: listening to music while playing a video game, or watching TV while talking on the phone, or even reading a newspaper while the TV is on.
3. Google reports make you feel smarter than you are
Internet search makes people think they know more than they actually do, he found new study.
And it doesn’t seem to matter much even if people don’t find the information they’re looking for.
“The Internet is such a powerful tool where you can enter any question and have virtually all the knowledge in the world at your fingertips,” said study leader Matthew Fisher.
“It becomes easier to confuse your own knowledge with that of an external source.
When people are really alone, they can be extremely inaccurate about how much they know and how dependent they are on the Internet.
4. Too much sugar damages memory
In general, healthy people with high blood sugar levels are more likely to have memory problems, according to a recent study. published in the journal Neurobiology.
Here is what one of the authors, Dr. Agnes Floel, says:
“… even for people with normal blood sugar levels, lowering blood sugar levels can be a promising strategy to prevent memory problems and mental decline with age.”
5. The “experts” know less than they think
The omniscient don’t know as much as they think they do, proves another study.
The more people think they know about a topic, the more likely they are to claim that completely fabricated facts are true, psychologists find.
Ms. Stav Atir, lead author of the study, explains:
“The more people were convinced that they had knowledge in the field of finance in general, the more they were inclined to claim that they knew fictitious financial terms.
The same pattern was observed in other fields, including biology, literature, philosophy, and geography.
For example, people’s assessment of how much they know about a particular biological term depends in part on how much they think they know about biology in general. ”
6. Bad sleep destroys mental abilities
The damage that bad sleep does to mental abilities is monstrous.
The sleeping brain needs to work harder, while short-term and long-term memory are weaker.
Attention and planning skills deteriorate, it is easier to follow habits and it is difficult to create new strategies.
Sleep deprivation even impairs the ability to read emotions on faces.
7. Physical exhaustion disrupts mental activity
Both mental and physical stress interact and cause fatigue, according to a recent study.
The brain’s resources in the prefrontal cortex – the area of the brain we use for planning and control – are separated during physical and mental activity, the study found.
It is one of the first to show how mental and physical tasks can interact and tire the brain.
