The world that we live in is filled with sounds, some are comforting and some could be jarring too. But what if the constant noise surrounding us is doing us more harm than we realize? There has been immense research that shows that noise is not just a nuisance, but a silent killer and affects our health in ways we do not even know. There are associations of sound causing heart attacks, type 2 diabetes, and dementia.
Noise is seen as an annoyance, but it effects can go beyond what we imagine. When we hear a sound, it travels through the ear to the brain. This is where it gets processed by the amygdala. It is a region that is responsible for emotional responses. This also triggers a stress response- our heart rate increases, our blood pressure rises, and stress hormones like cortisol flood our system.
This response is also designed to help us react to immediate threats. Especially, if we hear the sound of a predator approaching. However, when we are exposed to constant noise, this response is triggered repeatedly and could compel us to live in a long-term anxious state.
Many studies including Harvard Health and theAmerican College of Cardiology have found associations of noise with health problems including putting a person at a higher risk of cardiovascular diseases such as heart strokes, attacks, and high blood pressure. The constant activation of the stress response can take a toll on the body, increasing inflammation and making it harder for the heart and circulatory system to function properly. Over time, this can lead to serious health conditions like heart disease and diabetes.
Even more troubling, research suggests that noise pollution may contribute to mental health issues. Studies have found a strong connection between exposure to noise and disturbed sleep, which in turn can cause anxiety, depression, and cognitive decline. The World Health Organization estimates that noise contributes to around 12,000 premature deaths annually across Europe alone. This invisible threat, however, is often overlooked because the effects are gradual and cumulative.
One of the most insidious aspects of noise pollution is its impact on sleep. Even when we are asleep, our bodies are not fully immune to the effects of sound. Our ears never fully “turn off,” meaning that even faint noises can disrupt our sleep cycle. Research has shown that people who live in noisy environments—whether near busy roads, airports, or urban centers—often experience fragmented sleep, leading to fatigue and a weakened immune system. Over time, this chronic lack of restful sleep can lead to significant health problems, including an increased risk of developing cognitive disorders such as dementia.
As cities continue to grow, noise pollution is becoming more widespread. Traffic noise, in particular, is one of the most common and harmful sources. The rise of urbanization means more cars, buses, and trains, all of which contribute to an ever-increasing din. This urban soundscape is often relentless, with little respite for those living within it. In densely populated cities, people are exposed to high decibel levels, which can exceed safe thresholds for heart health. In many cases, the sheer volume of sound is not just unpleasant; it’s dangerous.
The solution is not as simple as reducing noise in our immediate surroundings, though efforts to reduce traffic noise and limit industrial sounds are essential. Some cities have taken steps to create quieter spaces by converting busy roads into pedestrian zones or installing noise barriers. These measures have shown to have a positive impact on public health, with research suggesting that even small reductions in noise can prevent premature deaths and improve overall well-being.

From being a macho dude, Bruce Willis’ personality has changed to becoming more ‘tender’ even as the 71-year-old action hero continues to battle dementia, according to his daughter Rumer.
“I’m so grateful I get to go see him,” Rumer, 37, said during a podcast interview. “Even though it’s different now, I’m so grateful.”
“There’s a sweetness. He’s always been this kind of macho dude, and there’s like a — fragile is not the right word, but — just a tenderness that maybe being Bruce Willis might not have allowed him in a certain way,” she added.
Bruce Willis is continuing into his third year living with the condition.
In March 2022, Bruce Willis, the media legend who dominated Hollywood in his prime, was diagnosed with dementia, and since then, his family has been sharing their struggle with his diagnosis and how slowly it has been taking a toll on his health.
The following year, his diagnosis was confirmed as frontotemporal dementia (FTD), which is a degenerative disease that slowly chips away at your motor skills, communication skills, etc. His wife, Emma Heming Willis, noted early signs were subtle changes in his speech, initially mistaken for a resurgence of his childhood stutter.
Rumer is the eldest daughter of Bruce and The Substance star Demi Moore, who were married from 1987 to 2000. The former couple also had Scout Willis, 34, and Tallulah, 32, together.
Although FTD is considered to be one of the rarest forms of dementia, Rumer said the disease is more “prevalent” than she realized.
“It’s wild to me. So many people come up to me now, and they say, ‘My uncle had FTD. My dad had this,” she said.

Earlier this year, in March, a hoax news of Bruce Willis’ death circulated. However, his representatives confirmed that the news is fabricated and that the actor is alive.
"He joins the long list of celebrities who have been victimized by this hoax. He's still alive and well. Stop believing what you see on the Internet," his official representative stated.
Frontotemporal dementia is a less prevalent type of dementia that mainly occurs in the frontal and temporal lobes of the brain. It tends to affect behavior, personality, language, and movement more than memory, particularly in its initial stages.
In contrast to Alzheimer's, which generally strikes older individuals, FTD can hit at an earlier age—sometimes as young as 40. The symptoms can range from changes in personality, emotional flatness, or the inability to show empathy to impulsiveness, so it is especially hard for spouses and children to cope.

The Mayo Clinic states that the symptoms of FTD vary depending on the most affected part of the brain. The progression is gradual but relentless.

Even as injectable aesthetic procedures are gaining popularity as "cosmetic" treatments in beauty clinics and wellness centers across the country, the Central Drugs Standard Control Organisation (CDSCO) has tightened rules around cosmetic use.
In a new public notice issued this week, the CDSCO stated that cosmetic products that come in injectable form do not fall under the definition of cosmetics under the law. It said that such products are not permitted for use by consumers, professionals, or aesthetic clinics.
"Cosmetic means any article intended to be rubbed, poured, sprinkled or sprayed on, or introduced into, or otherwise applied to, the human body," the notice said.
It added that cosmetics are for "cleansing, beautifying, promoting attractiveness, or altering the appearance."
Thus, "products supplied in the form of injectable preparation do not fall under the definition of cosmetics. No cosmetic is permitted to be used as injection by consumer/professionals/aesthetic clinics," the notice added.
The new rules bar professionals and stakeholders from using or manufacturing any cosmetic product intended for injection or medical purposes.
The move also seeks to curb misleading advertising and unauthorised cosmetic practices by clinics and individuals.

The regulator also warned against misleading claims and the use of prohibited ingredients in cosmetic products, saying such violations attract action under the Drugs and Cosmetics Act and Cosmetics Rules, 2020.
"Use of prohibited ingredients in cosmetic products, misleading claims on label, use of cosmetics for treatment, and application of cosmetics through injection attracts violations of the said Act & Rules," the notice said.
The regulator stated that no person shall alter, obliterate, or deface any inscription made by the manufacturer on the container or label of the product intended for use as a cosmetic.

The notice added that the list of generally not recognised as safe (GNRAS) and restricted ingredients is published by the Bureau of Indian Standards (BIS).
It has also encouraged the public and users to report any instance of misleading claims or violations through email and state licensing authorities.

The move follows several incidents of sub-standard cosmetic products found to be sold in the market, ranging from Botox parties in upscale salons to glutathione “skin whitening” drips offered in local aesthetic clinics.
Social media trends, celebrity endorsements, and growing demand for “preventive anti-ageing” treatments among younger consumers have driven the market for injectable beauty products, especially Glutathione drips, as well as detoxifying therapies, in the country.
Medical experts have also been raising concerns over their long-term safety and efficacy. As per experts, unregulated injectable procedures carry risks ranging from allergic reactions and infections to liver and kidney complications in extreme cases.
The new norms, thus, are part of the government's plans to strengthen the regulatory mechanism for cosmetics.
The government is also reportedly planning to designate a Central Cosmetics Laboratory to test cosmetic samples and may also designate any laboratory under its control for testing, according to Mint.
In addition, manufacturers will have to keep details and records of each batch and raw materials. Records are to be maintained for three years after the expiry of each batch. Imported cosmetic products shall bear a code number as approved by the State Licensing Authority.

Amid continuing heatwave conditions in northern India, prolonged exposure to extreme temperatures can trigger serious and potentially fatal medical emergencies, particularly among elderly individuals and cardiac patients, according to an expert.
The India Meteorological Department (IMD) has warned of severe temperatures across several states.
"Heat wave to severe heat wave conditions likely to continue to prevail over northwest & central India during the week and over East India during the next 5 days," the IMD said, in its latest update on May 20.
It added that severe heat conditions will persist for at least the next 72 hours across Delhi-NCR, Rajasthan, Uttar Pradesh, Punjab, and Haryana. Temperatures in several cities are expected to touch 47°C to 48°C, with Banda currently emerging as the hottest place in the country.
Dr. Vaibhav Mishra, Senior Director & Head, CTVS, Max Super Speciality Hospital, told HealthandMe that heat-related illnesses are not limited to discomfort or dehydration alone, and can rapidly worsen if early warning signs are ignored.

There are two major heat-related illnesses that people must understand so that timely precautions can be taken — heat exhaustion and heat stroke.
"Heat exhaustion is a milder and more common condition and typically occurs after prolonged exposure to high temperatures or intense physical activity in the outdoors," Dr. Vaibhav said.
Excessive sweating leads to significant loss of water and salts from the body, resulting in:
"However, if heat exposure continues and the body’s cooling mechanisms begin to fail, the condition can progress to heat stroke, which is a medical emergency. In heat stroke, body temperature often rises above 104°F," Dr Vaibhav told HealthandMe.
What may initially appear as confusion, disorientation, or irrelevant talking can rapidly worsen into:

Dr Vaibhav said that to cool the body during extreme heat, the heart has to work harder and beat faster so that more blood can be directed towards the skin for heat dissipation.
"This places additional stress on an already weakened heart. Many cardiac patients are also on medications such as diuretics, which increase fluid loss and dehydration. Certain blood pressure medicines may blunt the body’s normal response to heat and delay warning symptoms," the expert told HealthandMe.
Dehydration further thickens the blood and, combined with increased cardiac workload, can significantly raise the risk of heart attacks, strokes, and dangerous rhythm disturbances.
Dr. Vaibhav stressed the critical need for early recognition of symptoms, especially in vulnerable individuals such as elderly people and cardiac patients, who are much more susceptible to heat-related complications.
Simple preventive measures can save lives. These include
