Despite popular knowledge of the stress that loud music can bring, few are unaware of the damage that these noises can do to the heart. According to scientists, more sensitive people, such as the elderly, children and individuals with cardiovascular diseases, may experience a very high change in heart rate when they are exposed to noise pollution.

What does science say?
Basically, studies on the effect of noise pollution on our lives are quite old. In fact, the correlation between heart damage and loud noise has been studied for over 50 years. However, until the beginning of the 21st century, such promising or relevant results were not found.
However, about 10 years ago, scientists were able to identify the impact that loud sound can have on this organ. When the frequency is too high, it can stimulate the regions of the brain responsible for emotions. For this reason, our body begins to produce hormones that stimulate more adrenaline and cortisol, which can end up affecting the heart a lot.
The link between heart attacks and loud noises
In addition, updated data were found on the number of people hospitalized due to noise pollution. In 2018 alone, more than 16,000 people were hospitalized for a heart attack, where it was found that the rate of this problem was 72% higher in regions more prone to loud transport noise.
So, based on heart attack rates in different locations, the researchers estimated that exposure to noise was responsible for one in 20 heart attacks. Therefore, this condition started to count as one of the additional risk factors for cardiovascular diseases.
Soon, contact with noise pollution became part of the list of contraindications for cardiologists, especially for the most vulnerable individuals, such as those who underwent a surgical procedure in the heart. In fact, the recommendations also cover children, the elderly and animals. Therefore, it is important to be careful, especially in large human centers, where we are always surrounded by the sound of cars, concerts and others.
