Poor cognitive development in the room full of people!!!!

The more carbon dioxide there is in a room, the worse your decisions might be! This is the result of a new study according to which our decision-making skills are greatly affected in closed rooms. 

Room full of Carbon dioxide

The team from the State University of New York examined whether high CO2 exposure at school or at work could have a negative impact on our cognitive skills. 

The tests showed that the subjects' decision-making had already worsened at 1.000 ppm, compared to subjects in a room with 600 ppm CO2. (Typical outdoor concentration = ca. 380 ppm, indoors ca. 1.000, packed rooms = up to several thousand ppm.) Results were particularly impacted at 2,500 ppm.

Use it or lose it!!

You want your retired life should be like this as shown in the picture? , think again! A recent paper with the title “Mental Retirement” is currently suggesting that early retirement may lead to quicker memory decline.
According to study conducted by  Laura L. Carstensen from Stanford University, suggests that work actually provides an important component of the environment that keeps people functioning optimally.” The analysis of the data which was collected for the study suggested people may have to engage in stimulating activities to preserve memory and reasoning skills after their retirement.

The study which was published by economists Susann Rohwedder and Robert J. Willis in The Journal of Economic Perspectives supports the “use it or lose it” theory, further they also supports the idea that cognitively stimulating activities may delay cognitive aging. 

It was started about 20 years ago by the National Institute on Aging on a sample of 22,000 Americans who were submitted to memory tests every two years. Several European then started their own national studies and are being followed by countries such as Japan and Corea, using similar proceedings in order to obtain comparable data. It was found that “the longer people in a country keep working, the better, as a group and also lives healthy, think healthy!!!

Good news for Music lovers!!!

New research published in Neuropsychology shows that kids who take music lessons get a brain boost that lasts even into old age.

Researchers looked at a group of older adults between ages 60 and 83, and compared them based on how much experience they had playing music. Those who knew music or had practiced an instrument performed better on a variety of cognitive tests.
The head researcher Dr. Brenda Hanna-Pladdy mentioned that because music practice can be “a challenging cognitive exercise” it may help in “making your brain fitter and more capable of accommodating the challenges of aging.” She added, “Since studying an instrument requires years of practice and learning, it may create alternate connections in the brain that could compensate for cognitive declines as we get older.”
So thanks  mom-dad,  now I know that, all that torturous practice might help me keep my marbles as I age!
