You are becoming 'obsessive' because of these habits

Having daily habits still do really harm your brain.

Since the 30s of the twentieth century, the quality of life has been improved, which has also made the IQ of people all over the world increase significantly.

However, in the past 50 years, this index has tended to decrease. Affordable, convenient life is a double-edged sword for humans?

According to experts, perhaps the following habits of blocking the intellectual development will make you startled and give a plan to change yourself somewhat.

1. Pamper the stomach with fat

A study by the University of Montreal (Canada) has shown that consuming a lot of saturated fat will make your body and brain become stagnant . The reason is that they interfere with the function of dopamine - a neurotransmitter associated with movement.

According to studies, mice and some animals tested showed poor efficacy in cognitive flexibility, reaction time, memory and mental state when eating high-fat foods.

Saturated fats make the brain become stagnant.

Also, it's no coincidence that high-fat foods are called stomach-satisfying foods. Just like addictive substances, the more we eat fat, the more cravings and fat " doses " tend to increase until they become " mobile drums " to realize that no one is as fat as me .

2. Do many things at the same time

Earl Miller, a neuroscientist at the Massachusetts Institute of Technology, said: " The human brain is not designed to be multitasking ."

If we do many things at the same time, the brain is constantly moving from one job to another. This makes the energy consumed more and faster, and the work is not highly effective .

Breaking the head on the job also makes it impossible for the brain to accomplish its goal.

Many opinions are positive, for men, women with brains can handle many things at a better time. It is also possible, but in fact, having to switch back and forth between jobs makes the brain stressed and tired . That's why women are always compared like " grandma " because the stressed mind always makes them irritable and fastidious.

Preventing human creativity when having to do many things at the same time.

Besides, doing many things at the same time also prevents a person's creative thinking, because of interruption when constantly switching from one job to another. The reason is that the brain releases nerve-causing substances like cortisol and andrenaline.

3. "What is unknown, ask Google"

The era of technological development has given us a search engine dubbed the " knowledgeable professor ": Google.

However, modernity is harmful to electricity. Instead of remembering addresses, information or a recipe, we practice the habit of " asking " Google, and this inadvertently causes us to throw away our natural information storage engine - the brain .

Too reliant on Google makes the brain have a habit of relying on it, being lazy to think.

Research by Columbia University (USA) shows that we have a different way of remembering from the old days: remember the value of retention instead of remembering information.

The most obvious proof for this is that now we don't remember the phone numbers of friends and relatives, but remember how we saved each member's name in the directory to . find. This is quite disastrous when meeting emergency situations to make phone calls without remembering any numbers or having to ask for a series of numbers every time you lose your phone.

4. Plug in the roots to watch movies / shows all day

Everyone knows watching movies for too long has a negative impact on health. But few know that these movies and reality TV shows also affect our perception.

Because in the process of viewing, the content, their details - the things you often see and think about - will more or less dominate your thoughts and actions . Therefore, every time you watch a movie, you often feel it " stuck " in your head and sometimes you act like a movie character.

Plowing movies all day makes the brain work too much.

It is not difficult to see why violent or horror movies often prohibit children.

5. Foreign travel regularly

Traveling to increase the experience is also good, but frequent travel makes your biological clock always wrong, which is another matter.

Time zones can only make you feel tired for a day after landing, but its effects can last for weeks. Research on hamsters shows that regular biological clock disorders cause the number of neurons to be born to be halved in the memory processing area.

Foreign travel regularly will lead to biological clock disorders.

Remarkably, the effects were still significant after a month since their last calendar was overturned. Besides, the ability of mice to absorb is also reduced.

This means that if you are going to choose the things you regularly do in changing hours and " different people " like flight attendants, medical staff, shift workers, you should carefully consider the pictures. Effect of working hours on health.

6. Chew gum

We used to think chewing gum is good because it helps both focus and clean teeth.

Chewing gum too long prevents short-term memorization activities.

Scared! Chew the candy for less fear

However, a recent test has poured cold water on people who like to chew gum. Testing indicates that this action only works at first. After chewing gum, chewing will cause distraction when performing short-term memorization activities.
