Exposure to airborne ultrasound causes head related diseases

New Delhi: Places like railway station, museums, sports stadium, libraries, schools has higher expose to airborne ultrasound which can lead to diseases like nausea, dizziness, migraine, fatigue and tinnitus.

According to the university of Southampton, people are being exposed to airborne ultrasound without their knowledge in public places. Loudspeakers, door sensors, public addressing system can generate airborne ultrasound in public places.

Professor Tim Leighton collected readings of very high frequency/ultrasonic VHF/US fields in several public buildings using smartphones and tablets equipped with an app. The findings were then calibrated with two or three independent microphone and audio data systems.

Study author Professor Tim Leighton found that members of the public were exposed to VHF/US levels over 20 kHz, which is the threshold of the current guidelines.

People who are unaware of this airborne exposure are complaining, for themselves and their children.

One in 20 people between the age of 40-49 years is suffering from hearing threshold that is a minimum of 20(DB) which becomes more sensitive at 20KH than that of people aged between 30-39.

Five percent of the People between the age of 5-19 are likely to have 20KH threshold that of 60(DB) more sensitive than the median for the 30-39 year age group.

The current reports are not capable for fighting with the mass exposure, which a large number of people is facing. Current guidelines are not meeting the requirements for such a large public who is being exposed to airborne ultrasound. These guidelines are roughly collected on the basis of small groups’ mainly male adults.

Over a period of time, many workers are being exposed to occupational industrial ultrasound through industrial devices for cleaning and drilling which affects them negatively.

It’s very much necessary that suffers can able to identify whether they are suffering from  VHF/US exposure or not. The lack of research states that it is not possible to prove or disprove the health risk of public.(IANS)(Image-huffingtonpost)

Here’s How Belly Fat Increases the Risk of Heart Attack

Belly fat may lead to multiple heart attacks

Heart patients, please take note, here’s a new health news. Researchers have found that heart attack survivors who carry excess fat around their waist are at increased risk of another heart attack.

“Abdominal obesity not only increases your risk for a first heart attack or stroke, but also the risk for recurrent events after the first misfortune,” said study author Hanieh Mohammadi from the Karolinska Institute in Sweden.

Prior studies have shown that abdominal obesity is an important risk factor for having a first heart attack. But until now, the association between abdominal obesity and the risk of a subsequent heart attack or stroke was unknown.

The research, published in the European Journal of Preventive Cardiology, followed more than 22,000 patients after their first heart attack and investigated the relation between abdominal obesity (measured by waist circumference) and the risk for recurrent cardiovascular disease events. The researchers specifically looked at events caused by clogged arteries, such as fatal and non-fatal heart attack and stroke.

Patients were recruited from the nationwide SWEDEHEART registry and followed for a median of 3.8 years. Most patients — 78 per cent of men and 90 per cent of women — had abdominal obesity (waist circumference 94 cm or above for men and 80 cm or above for women).

Increasing abdominal obesity was independently associated with fatal and non-fatal heart attacks and strokes, regardless of other risk factors (such as smoking, diabetes, hypertension, blood pressure, blood lipids and body mass index [BMI]) and secondary prevention treatments. According to the researchers, waist circumference was a more important marker of recurrent events than overall obesity.

The reason abdominal obesity is very common in patients with a first heart attack is that it is closely linked with conditions that accelerate the clogging of arteries through atherosclerosi, the researchers said. These conditions include increased blood pressure, high blood sugar and insulin resistance (diabetes) as well as raised blood lipid levels.

“Our results, however, suggest that there may be other negative mechanisms associated with abdominal obesity that are independent of these risk factors and remain unrecognised,” Mohammadi said.

“In our study, patients with increasing levels of abdominal obesity still had a raised risk for recurrent events despite being on therapies that lower traditional risk factors connected with abdominal obesity such as anti-hypertensives, diabetes medication and lipid lowering drugs,” she added.

According to the study, the relationship between waist circumference and recurrent events was stronger and more linear in men.

“There were three times as many men in the study compared to women, contributing to less statistical power in the female group. Therefore, more studies are needed before definite conclusions can be drawn according to gender,” Mohammadi noted. (IANS)
