Noise outside the window increases the risk of dementia

1

Living in noisy areas increases the likelihood of developing dementia, as suggested by the study. An increase in the average noise level by just 10 decibels increases this risk by 30%.

If there is continuous noise from moving cars outside your window, and there is a railway line or airport nearby, the likelihood of encountering senile dementia increases significantly. The noise level is a factor by which a number of ailments can be predicted. An increase of just 10 decibels (the difference between breathing and whispering) increases the risk of developing dementia by 30%.

The risk of moderate cognitive impairment, including memory and thinking skills, also increases by 36%, according to scientists from the University of Michigan. They followed 5,227 people over 65 in Chicago and identified risk factors for dementia. These included air pollution, lead poisoning, and increased noise levels from railroads, cars, airplanes, industrial plants, and construction.

The noise levels in the study ranged from 51 to 78 decibels. This is the difference between living in a quiet neighborhood and living near a busy freeway. The results of the study were published in the scientific journal Wiley. For every 10-decibel increase in noise levels, the risk of dementia increased by almost a third. This means that if the noise level increases by 30 decibels, the likelihood of Alzheimer's disease increases by almost 100%.
