The noise makes you fat, found association between noise and extra pounds
The noise makes you fat Swedish study shows association between noise pollution caused by traffic and extra pounds on the waistline.
Honking, cars and scooters cause a continuous din which for many is hard to find shelter. Often we have no respite even during the night when, protected inside the buildings, we still disturbed in his sleep by the constant buzz from the street. The traffic is a source of great stress for the inhabitants of large cities, especially for those who live close to busy roads. The news is that there may be a link between noise pollution caused by traffic and the extra pounds, especially around the waist. This is the conclusion of a Swedish study that observed an association between obesity and exposure to environmental noise, a factor of great physiological stress.
STUDY ON SWEDISH BETWEEN 43 AND 66 YEARS I
The study from the Karolinska Institute, published in the journal Occupational and Environmental Medicine and has immediately gained the attention of the media, was conducted on 5,075 Swedes aged between 43 and 66 years, residents in rural and urban areas – close to noise sources such as air traffic, road and rail – Stockholm and followed for about five years. The researchers, authors of a study on the relationship between noise and hypertension on the same group of individuals, who have seen more than 45 decibels, the noise comparable to that of a conversation, with each increase of five decibels was associated with an increased waistline about 0.2 centimeters. Increase, it must be said, modest and not able to put at risk the health of an individual in the form, but it underlines the importance of the sound levels of the environment in which we live. The study concentrated on the acoustic and failed to investigate other factors such as the effects on the body of pollutants emitted by vehicles noise makers or socio-economic factors impact on the lifestyles of potential interest.
NOISE CAUSE STRESS AND ALTERA SLEEP
Caution is required in interpreting the results of this study does not demonstrate any causal relationship, but only an association between traffic noise and overweight. Among the possible causes put forward by Swedish scientists will be the effect of noise on sleep quality and cortisol, the stress hormone. The increase of cortisol in response to noise pollution has also been shown in previous studies on the physiological reactions of stress and we know that this hormone promotes the accumulation of abdominal fat.
NOISE POLLUTION CASE EVEN Metabolic
According to the World Health Organization (WHO), the noise from traffic – after air pollution – is a serious environmental problem across Europe. The multiple effects on the human body, as confirmed by a growing scientific literature, regarding an increased risk of cardiovascular and metabolic diseases, such as hypertension, heart attack and stroke.
