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.

Performing short and intense exercises that last for about 10 minutes may significantly reduce the risk of colorectal cancer, a British study shows.
Researchers at Newcastle University have found that completing brief workouts increases the concentration of several small molecules in the blood that have previously been linked to reducing inflammation, improving blood vessel function and metabolism.
The findings, which were published in the International Journal of Cancer, also noted that even short bouts of exercise can influence the activity of genes that govern tumor growth and fight against cancer.
Dr Sam Orange, Senior Lecturer in Clinical Exercise Physiology at Newcastle University and lead study author, said of the results, "What’s remarkable is that exercise doesn’t just benefit healthy tissues, it sends powerful signals through the bloodstream that can directly influence thousands of genes in cancer cells.
“It’s an exciting insight because it opens the door to find ways that mimic or augment the biological effects of exercise, potentially improving cancer treatment and, crucially, patient outcomes.
“In the future, these insights could lead to new therapies that imitate the beneficial effects of exercise on how cells repair damaged DNA and use fuel for energy.”
Researchers had asked each volunteer to complete a short, intense cycling test that lasted about 10 minutes and collected each of their blood samples which were then meticulously analyzed.
After studying about 249 proteins, the experts found nearly 13 protein had increased in their blood flow after the short exercise including interleukin-6 (IL-6), which helps repair the DNA of damaged cells.
When these exercise-induced proteins were applied to colorectal or bowel cancer cells by the scientists in a lab, they discovered that these new proteins could alter the activity of over 1,300 genes, particularly those who were responsible for DNA repair, energy production and cancer cell growth.
As a result, they concluded that performing even small exercises can activate a set of genes in the body's cells that can support efficient use of oxygen and promote energy metabolism. Additionally, the British researchers also discovered that the cell genes which have been previously associated with rapid cell growth were switched off after working out, suggesting that this might aid in controlling cancerous growths in the body.
Colorectal or bowel cancer is a common cancer that forms in the tissues of the colon (large intestine) or rectum, often starting as non-cancerous growths called polyps that turn cancerous over time.
Despite being treatable and preventable, colorectal cancer is currently the second leading cause of cancer-related deaths worldwide. Over 70,000 new cases of colorectal cancer occur annually in India, making it the fourth most common cancer in the country.

When temperature drops, so does the moisture even in your skin. This is what leads to a rash or allergies. In fact, with changes in temperature, and winters, our lifestyle changes too, this could also be the reason why we experience a winter rash, or allergies. To understand this better, Health and Me spoke to Dr Navjot Arora, Consultant Dermatologist, Dermaheal Skin and Clinic at Dwarka, Delhi, who explained that allergies and skin rashes tend to increase during winter due to both, environmental factors and changes in skin health. "Cold temperatures and low humidity levels reduce moisture in the air, leading to excessive dryness of the skin. When the skin becomes dry, its natural protective barrier weakens. This makes it more prone to irritation, inflammation, and allergic reactions."
The doctor explains that during winter, people tend to stay indoors more, and it also increases their exposure to allergens like dust mites, mold, pet dander, and chemical fumes from heaters and cleaning products. "Limited ventilation and closed spaces allow these allergens to build up, triggering allergic responses and skin rashes, especially in individuals with sensitive skin or pre-existing conditions like eczema."
Cold weather also affects blood circulation to the skin. Reduced blood flow can slow down the skin’s repair process and weaken its defense against irritants and allergens. As a result, chronic skin conditions such as eczema, psoriasis, and contact dermatitis often worsen in winter, leading to itching, redness, flaking, and rashes.
Doctor also points out that during winters, our bathing habit changes. Dr Arora says, "Frequent hot showers strip away the skin’s natural oils, increasing dryness and irritation. In addition, wearing heavy woolen or synthetic clothing can cause friction, sweating, and contact allergies, particularly in skin folds, which can further contribute to rashes."
If not treated well, or in time, it can develop into more serious health threat, especially if you have a family history of
The rise in allergies and rashes during winter is largely linked to dry weather, indoor allergen exposure, and skin barrier damage. Maintaining proper skin hydration, avoiding harsh soaps, limiting hot water exposure, and wearing skin-friendly fabrics can help reduce the risk of winter-related allergies and skin rashes.
Moisturizers are usually the first line of care for dry skin because they help trap moisture and prevent further dryness. Apply them multiple times a day, especially after bathing or washing your hands. Thicker options like creams or ointments tend to keep skin hydrated longer than lighter lotions.
Petroleum jelly can also be effective, as it forms a protective barrier that seals in moisture. If you prefer to avoid petroleum-based products, alternatives like Waxelene or Un-Petroleum work in a similar way to reduce moisture loss.
Natural virgin oils, such as coconut oil, may help calm irritated skin and restore hydration. Use them on areas that are not acne-prone, and always do a patch test on a small area for 24 hours before wider application.
Oatmeal-based soaps or oatmeal baths can also help soothe dry, itchy skin. You can buy ready-made oatmeal soaps or add finely ground oats to a warm bath and soak for about 10 minutes.
For itching and inflammation, topical hydrocortisone creams, available over the counter or by prescription, may provide relief. Always follow the instructions on the label or use them as advised by a doctor.

The NHS has released updated guidance for people who are currently taking clonazepam, a commonly prescribed medicine that belongs to the benzodiazepine group. According to the health service, clonazepam is often used to control seizures or fits linked to epilepsy, ease involuntary muscle spasms, and help manage panic disorders. It is also prescribed in some cases for people with restless legs syndrome (RLS). NHS Inform notes that “around 1 in 10 people experience restless legs syndrome at some stage in their life.”
Explaining how the drug works, the NHS says it increases levels of gamma-aminobutyric acid (GABA), a chemical in the brain that has a calming effect. By boosting GABA, clonazepam can reduce anxiety, prevent seizures or fits, and relax tight or overactive muscles.
Clonazepam is only available on prescription and comes as tablets or a liquid. Most adults aged 18 and over can take either form. In certain cases, children as young as one month old may be prescribed clonazepam to treat epilepsy, as per NHS.
That said, there are situations where extra caution is needed. People who are due to have surgery or dental treatment, those who are pregnant, trying to conceive, or who have sleep-related conditions may be advised to stop taking the medicine. However, these are not the only groups the NHS says should be careful.
Clonazepam is not suitable for everyone. Before starting treatment, patients are advised to tell their doctor if they:
Like many medicines, clonazepam can cause side effects. Common effects, which affect more than 1 in 100 people, include disturbed sleep such as vivid dreams, feeling sleepy during the day, light-headedness, dizziness, unsteadiness, and muscle weakness.
When it comes to long-term use, the NHS warns that clonazepam can lead to withdrawal symptoms if taken for a prolonged period. Because of this risk, people who have been prescribed the drug for more than four weeks may have their dose reduced slowly when stopping treatment, rather than stopping suddenly.
The NHS also stresses that this is not a complete list of side effects. Patients are advised to read the information leaflet that comes with their medicine for full details.
Although uncommon, some people may experience serious side effects while taking clonazepam. The NHS advises contacting a doctor or calling 111 immediately if you notice:
In rare cases, clonazepam can trigger a serious allergic reaction known as anaphylaxis.
