Aerial noise will increase blood pressure when you sleep

Dr Lars Jarup, the head of the study, said: The greater the noise, the higher the blood pressure in humans, and people living near airports will have a greater health risk.

High blood pressure can lead to sudden death, heart failure, heart attack and kidney failure. High blood pressure affects more than 1 billion adults worldwide. ' Living near the airport is a serious problem, you will be exposed to the noise of night flights ,' said Jarup, Imperial College London environmental health researcher.

The research was funded by the European Commission and published online in the European Heart Journal .

Previously, researchers have shown that people who live near noisy airports and under flight for at least five years are at greater risk of developing chronic hypertension than those who live in a quieter place. Previous research on nearly 5,000 people showed that the noise of nighttime 10dB aircraft would increase the risk of blood pressure by as much as 14% in both men and women.

'We understand that noise from vehicles often causes frustration. However, our research shows that noise is also harmful to human health , which is very important for international airport expansion projects, ' Jarup said.

Latest research

In a recent four-year study, researchers measured remote blood pressure of 140 volunteers every 15 minutes when they were sleeping at home near England's Heathrow airport - the busiest airport in the world, and 3 other key airports of Europe.

They use digital voice recorders to identify which noises affect most blood pressure, with the intensity range from road vehicles to snoring and the sound of aircraft taking off and landing.

The researchers discovered that the blood pressure of volunteers increased after they heard noises greater than 35dB, an average of 6.2 millimeters of mercury for systolic blood pressure and 7.4 millimeters. for diastolic blood pressure.

The blood pressure of volunteers increases whether they wake up or not.

The dB intensity of noise is an important factor, but the aircraft has the most significant effect, Jarup said. He said: 'You will see that road traffic noise is not so bad at night. But if you live near the airport where there are night flights, that's a completely different story. '
