Why noise irritates some people more than others: It's all in the brain
Noise sensitivity, often dismissed by health professionals, can significantly impact both mental and physical wellbeing. Affecting up to 40% of the population, this condition is linked to anxiety, sleep disturbances, and long-term health risks. read more While noise sensitivity is often overlooked by health professionals, it can have long-lasting effects on the mental and physical wellbeing of humans. Studies suggest that between 20% to 40% of people are more sensitive to everyday sounds than the average, leading to a higher levels of stress, annoyance, or anxiety. Research shows that noise sensitivity has biological roots rather than being just a personality trait. In recent years, neuroscientists have discovered that the brains of noise-sensitive people process sound differently, which might make them more reactive to noise. STORY CONTINUES BELOW THIS AD Daniel Shepherd, a neuroscientist at Auckland University of Technology in New Zealand stated, 'It's been one of those what we might call a wastepaper basket sort of issues… that just gets pushed away by health professionals." Only in recent years 'have people actually really started to say, right, this is at an experiential level really impacting patients', he added. 'We really need to actually start getting a handle on this.' Although noise sensitivity is not a formal medical diagnosis, but it can be identified via questionnaires like the 21-question Weinstein's noise sensitivity scale, which assesses reactions to various everyday sounds. It differs from similarly related conditions such as misophonia, which involves a strong negative reaction to specific sounds like chewing or tapping, or hyperacusis, where sounds are perceived as louder or more painful than they really are. In contrast, noise sensitivity includes a heightened reactivity to a wide range of sounds, irrespective of its volume. Physiologically, the noise can trigger a 'fight-or-flight' response in sensitive individuals, and can raise their heart rate and blood pressure. In some cases. sleep can also be affected. A 2021 study of 500 adults in China found that while noise itself did not drastically change sleep quality, noise-sensitive participants reported feeling less rested and more fatigued the day after. STORY CONTINUES BELOW THIS AD There are connections to long-term health as well. Research led by Professor Stephen Stansfeld at Queen Mary University of London found that noise-sensitive men in the Welsh town of Caerphilly were more likely to face anxiety and depression when exposed to road traffic noise. A 2023 French study of residents near airports reported that those who were highly disturbed by aircraft noise were more likely to rate their general health as poor. Brain studies provide more insights. According to Shepherd's research, noise-sensitive individuals have increased brain activity in response to both threatening and non-threatening sounds. This may be linked to differences in the medial geniculate nucleus, which is a part of the brain that filters sound information, which appears less efficient at filtering out irrelevant noise. The reduced filtering is also observed during sleep, where fewer brain 'spindles' happen, making it harder to adapt to background noise. The causes of noise sensitivity are still being explored. While twin studies from Finland suggest there might be a genetic component, environmental factors might also play a role. STORY CONTINUES BELOW THIS AD The condition is more common in individuals with anxiety, schizophrenia, autism, or a history of brain injury, and it often lasts a lifetime. Addressing noise at its source looks like the most effective long-term solution. Urban planning measures like sound-dampening road surfaces, noise barriers, reduced speed limits, and quiet zones have been put in place in some European cities. However, the change is slow, and many people cope with noise sensitivity symptoms by themselves by using ear protection, or noise-cancelling devices. In certain cases, treating underlying issues like anxiety with medication or cognitive behavioural therapy can help lessen the stress. Music therapy that uses soft, calming tunes, such as Renaissance or Baroque chamber music, may also be useful. Art therapy can offer a different way to relax and manage emotions. While noise is an unavoidable part of modern life, understanding its effects on sensitive people could lead to better public health measures and, ultimately, quieter and healthier living environments.

Rock Legend Dave Edmunds Fighting For Life After Having 'Died In Arms' Of Wife
Rock musician Dave Edmunds 'died in arms' of wife until nurse revived him. The 81-year-old is reportedly now fighting for life after 'major' cardiac arrest. The rocker was hospitalised in late July, as per a post by his wife Cici Edmunds. Dave was taken to an intensive care unit, where he was intubated, she wrote. As per her, Dave 'clearly has brain damage and severe memory loss,' among other ailments. There is a risk of the Welsh musician experiencing another cardiac arrest. In case of a second attack, there would be 'no chance' for survival, wrote Cici. Full report-

Shingles vaccine & lower dementia risk: what new study says
The shingles vaccine may do more than protect against the viral infection. Those vaccinated have a 23% lower risk of developing cardiovascular conditions, a recent study from South Korea found. But perhaps even more significant is a 'natural experiment' from Wales that confirms what health records have long suggested — that getting the shingles vaccine reduces the odds of the onset of dementia, a debilitating neurodegenerative disorder which does not yet have very effective treatments. Shingles is a viral infection that causes painful rashes. While shingles can occur anywhere on the body, it typically looks like a single stripe of blisters that wraps around the left or right side of the torso, along the path of the nerve from which the virus spreads. It is caused by the varicella-zoster virus — the virus which also causes chickenpox. After a bout of chickenpox, usually during childhood, the virus remains dormant in one's nerve cells for life. It can reactivate and cause shingles when a person's immune system is weakened. People who have never had chickenpox may get the infection if they come in direct contact with the fluid released by the shingles rashes, or breathe in the virus particles. Pain can persist even after rashes go away. In severe cases, the rashes cause vision loss if they are close to the eye, facial paralysis, or inflammation of the brain. The shingles vaccine, which prevents the reactivation of the varicella-zoster virus, is recommended primarily to individuals over the age of 50 years. It may also be recommended to adults living with a weakened immune system due to conditions such as HIV. Previous studies shown an association between shingles vaccination and lower risk of dementia. But most of the evidence has come from patient records, which are subject to one major bias: people who are vaccinated tend to take better care of their health. The unique roll-out strategy of the shingles vaccine in Wales created a 'natural experiment' that effectively mimicked a randomised control trial, the most credible level of evidence in medical research, much better than patient records. The programme, which began on September 1, 2013, allowed anyone who was between 79- and 80-years-old on that date to get the shingles vaccine over the next year. While 78-year-olds could receive the vaccine the year after, those above the age of 80 would never be eligible. This created a natural cohort of people — of similar age and living in similar conditions — only half of whom were eligible to receive the shingles vaccine. Upon analysing the health outcomes of this cohort, the Welsh study published in Nature last month found that dementia diagnoses among people who had gotten the shingles vaccine reduced 3.5 percentage points over a seven-year period. This equates to a 20% lower relative risk of getting dementia compared to the unvaccinated population. Scientists are yet to determine what might be behind this. One theory looks at the shingles-causing virus which has been linked to long-lasting cognitive effects. Preventing its reactivation through vaccination, could directly reduce the risk of dementia. Some researchers have also pointed to changes in the immune system brought about by the shingles virus which could protect against dementia. There are two approved shingles vaccines — both of which are available in India for a price of Rs 6,000 to Rs 17,000 per dose. Zostavax uses a live, weakened virus, while Shingrix uses a recombinant technology to develop parts of the virus that do not cause the disease. The Welsh study was based on people who had received the older Zostavax vaccine. However, a study from Oxford University last year showed that the new recombinant vaccine may also offer protection against dementia. The study, based on the health records of 200,000 persons in the US, found a 17% reduction in dementia diagnoses in the six years following immunisation with Shingrix. Note that there is also some evidence linking lower dementia risk with other common vaccines. Published in Alzheimer's & Dementia, a recent study covering 130 million people found a correlation between a lower risk of dementia and the hepatitis A, typhoid and diphtheria vaccines. Another 2023 study in the Journal of Alzheimer's Disease found the diphtheria, pneumococcal and shingles vaccine to be associated with a 30%, 27%, and 25% reduction in the risk of dementia.
