Traffic noise increase heart attack risk: Study

LONDON — Researchers have found that the amount of traffic noise to which you are exposed increases the risk of heart attack.

The increase in risk – though slight – is greatest with road and rail traffic noise, less with aircraft noise, researchers said.

For the study Andreas Seidler from Germany’s Dresden University of Technology and his co-authors assessed data from statutory health insurers on over a million Germans over the age of 40.

In this case-control study of secondary data, the addresses of persons living in the Rhine-Main region were matched precisely to road, rail, and traffic noise exposure measurements for 2005.

When the analysis was restricted to patients who died of heart attack up to 2014/2015, a statistically significant association was found between noise exposure and the risk of heart attack.

The authors believe the lower risk from aircraft noise can be explained by the fact that, unlike road and rail traffic noise, aircraft noise never remains continuously above 65 dB (decibel).

They also see indications from their analysis that exposure to traffic noise influences not just the genesis, but the course of a heart attack.

Although strictly speaking these results show only an association between traffic noise and heart attack, the authors believe that the sheer numbers of people affected by noise pollution mean that it is now right to start intensive efforts towards effective prevention of traffic noise.

This study is part of the Europe-wide NORAH (Noise-Related Annoyance, Cognition, and Health) study investigating the health consequences of traffic noise.

The findings appeared in the journal Deutsches Arzteblatt International.

KATHMANDU — Nepal Airlines Corporation (NAC) — the national flag carrier which bought two wide-body aircrafts — is exploring new destinations in Europe, North America and South East Asia to bring in more tourists to the country.

The NAC, with the new destinations, expects to increase its business and carry 400,000 tourists on board the NAC planes to Nepal every year.

The NAC’s move is expected to serve largely for the government’s announcement to mark 2020 as Nepal Visit Year.

The NAC is also planning to procure narrow-body planes that would make regional flights while the wide-body planes would fly to the new international destinations.

For the new destinations, the NAC has appointed issue manager.

With the agreement, the NAC planes would make flights to 14 destinations in a week. If things go as planned, the NAC planes would fly to Narita and Tokyo in Japan, easing the tourists visiting Nepal from there.

After getting approval from Japan and South Korea for flights, the inclusion in the significant safety concern list by the EU to Nepal would remove automatically while the flights to South Korea shall open up the golden door for Nepal Airlines.

South Korea is regarded as the safest country in the world in terms of civil aviation. Likewise, the ICAO has already removed Nepal from its blacklist.

Furthermore, the NAC is preparing to operate flights to bring in tourists from Sri Lanka, Pakistan, Indonesia and Vietnam.

Similarly, Minister for Culture, Tourism and Civil Aviation Rabindra Adhikari has directed the NAC for announcing new business plans by targeting the Indian and Chinese tourists, realizing the crucial role of the national flag carrier to make the Nepal Visit Year 2020 a success.

“Top priority has been given to the NAC as it is the major basis to bring in tourists,” Minister Adhikari shared.

Likewise, Minister Adhikari shared that expansion of services and facilities of the Tribhuvan International Airport has been prioritized.
