A study published in the journal Trends in Genetics explains that humans have lost their cleverness when he was a caveman who use tooth tigers that have been honed as a weapon.
But this condition is still slowed by a number of ways such as exercise or continue to sharpen the brain by reading or playing crosswords. Also, avoid also five things that could make your brain power decreases as quoted by FoxNews, Thursday (11/29/2012) following.
1. Abusing Google
You remember eating at a famous restaurant in a town that once you visit. But because so lazy, you are reluctant to use your brain to remember the name of the restaurant, then use Google to find out his name.
According to a study in 2011 from Columbia University, has basically an online search engine that can be used anytime to make you super comfortable but that is often overlooked is that you are also going to be a super forgetful.
When you are constantly using Google to find out about everything, in fact you do not help yourself to remember something.
It's better when you want to remember something, repeat and shout that information multiple times in a loud voice. Maybe you'll sound crazy but this exercise is one of the best tricks to keep your memory health.
2. Everywhere by car
Even cavemen are not doing cardio exercises but wherever she goes, man caves have thousands of miles, and it was done only by foot. Unlike modern humans anywhere up vehicles such as cars. The problem is the low level of fitness a person is far more painful than just physical pain.
A study in 2011 also found that the striatum, the part of the brain associated with memory function and performance of the people who are not athletes is smaller than the striatum owned basketball player.
Lucky it can still be overcome by doing aerobic exercise for a year because based on studies from the University of Illinois, these activities can increase the size of the adult hippocampus as much as 2 percent.
Moreover, experts believe that if the sport can balance the chemical composition of the compound in the brain, strengthening the connections in the brain, including the brain adds strength.
3. Would rather eat fries than salads
Obesity rates continue to rise turns humans since time immemorial. I was so high up to now more than two-thirds of Americans have been declared by the CDC as being overweight.
And brains of obese people have to work harder than people with normal weight in order to achieve the same results. This was revealed by a team of researchers from Carnegie Mellon University.
Because high blood pressure and inflammation, which are both obese attack will disrupt communications network brain nerves of the brain that makes it difficult to receive a variety of messages or information coming into the brain.
4. Kept locked in the office
In a recent study of 22 people, a team of researchers gave participants a test of decision-making while pumping up a room filled with carbon dioxide. (Normal levels of carbon dioxide in the air was 600 ppm, but in this study the levels increased to nearly 2500 ppm).
From there, researchers found that the higher levels of karbondioksidanya the level of concentration and ability to make the strategy even further down. Could be it was because of the excess CO2 in the blood leading to a reduction of oxygen in the brain.
According to NASA research, a number of plants such as peace lily, and the lady palm proven to cleanse the air of pollutants. Yet still the best option falls to fresh air. 15-minute exposure to fresh air alone can help increase oxygen levels in the brain.
5. Frequent business trips abroad
Time zone differences are not just making a mess of one's sleep patterns, but also the level of intellect. This was confirmed by a team of researchers from Cal Berkeley after conducting experiments to change the number of hamsters sleep schedule every 3 days once in a period of one month. Hamster-hamster sleeping pattern was changed as well as changes in sleep patterns when a person is traveling from New York to Paris.
As a result, the hamsters were experiencing 'jetlag' proved to be not as smart as they do not experience it. In detail, the hamsters 'jetlag' only produces 50 percent fewer neurons than when their sleep patterns were normal.
Researchers also suspect this is caused by low production of the sleep hormone (melatonin) and increase the production of stress hormones (cortisol), including increasing the number of cells that die from lack of sleep.
