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.

For people who work, laptops and computers are something we use every day. Sitting in front of a screen for hours can be bad for your neck and spine. When you sit and use your laptop the way you position yourself can hurt your neck over time.
This is true even when you are just scrolling on your phone. Keeping your head bent for a long time can put stress on the muscles and joints in your neck.
The problem is not the laptop itself but how we use it. Many people spend hours looking down at a screen without realizing it. This can cause muscle fatigue, stiffness, headaches and neck pain that will not go away.
Your neck is meant to support your head and let you move it around. When you keep your head tilted forward for hours the muscles in your neck have to work hard to keep it that way. Over time this can cause discomfort. Make it harder to move your neck.
If you sit with posture it can also affect the normal curve of your neck. Poor posture may not cause spinal problems on its own but it can cause wear and discomfort. This is especially true for people who already have neck or spine problems.

Delhi has issued a public health advisory amid a sharp rise in H1N1, commonly known as swine flu, cases. Health authorities urging residents to follow respiratory hygiene, avoid crowded places and seek medical advice if flu-like symptoms develop.
The national capital has reported more than 1,777 H1N1 cases so far this year, including 114 new infections recorded on August 20 alone, according to the latest health department data. Overall, Delhi has reported more than 2,300 Influenza-A cases in 2026.
The sudden surge has prompted the Centre and Delhi authorities to step up surveillance and hospital preparedness. Health officials have also stressed that people should not panic but take necessary precautions to avoid getting sick.
According to health department, Delhi had recorded 2,392 Influenza-A cases by August 21, of which 1,777 were H1N1. The tally also included H1 and H3 infections and other Influenza-A strains.
The current number is significantly higher than the corresponding period last year. Public health experts have also described some of the H1N1 cases being seen this season as relatively severe.
Dr Chandrakant Lahariya, a public health expert, said H1N1 is not a new subtype and has been known for years, but the current surge needs to be taken seriously.
Doctors have linked the increase to the seasonal pattern of respiratory infections during the monsoon, when humidity, changing temperatures and increased indoor contact can facilitate the spread of respiratory viruses.
Dr Neetu Jain, senior consultant in pulmonary, critical care and sleep medicine at PSRI Hospital, told PTI, “H1N1 cases are particularly high in Delhi-NCR this year.”
She also said the number of cases was reported to be around six times higher than previous years and noted that high temperatures and humidity may contribute to the increase in flu and other viral infections.
H1N1 infection can mimic other viral respiratory illnesses. Common symptoms include:
Some people recover without complications, but influenza can become serious, particularly in young children, older adults, pregnant women and people with weak immune systems.
Difficulty in breathing, chest pain, drowsiness, low blood pressure, bluish discolouration or worsening of an existing medical condition are among warning signs that need urgent medical attention.

With flu cases rising, doctors are also urging people not to assume that every fever or cough is H1N1 and start medicines without medical advice.
Dr Jain described H1N1 as a “fairly treatable illness”, while noting that it can become serious in vulnerable people. Antiviral medicines may be prescribed in appropriate cases, along with supportive treatment.
The Delhi government's advisory recommends several basic measures to reduce transmission. People are being urged to wear masks in crowded places, cover their mouth and nose while coughing or sneezing, wash their hands frequently and avoid close contact with people showing respiratory symptoms.
Residents have also been advised not to touch their eyes, nose or mouth unnecessarily and to avoid spitting in public places.
People who develop flu-like symptoms should stay away from others where possible and seek medical advice, particularly if symptoms become severe.
Authorities have also increased monitoring across the healthcare system. Thirty-five hospitals are under special surveillance, while referral laboratories at AIIMS and the National Centre for Disease Control (NCDC) are available for testing and confirmation.
Hospitals and district health authorities have been asked to strengthen monitoring of influenza-like illness, severe respiratory infections and COVID-19.
Union Health Minister JP Nadda has also reviewed Delhi's preparedness amid the rise in H1N1 cases, with authorities instructed to focus on surveillance, early detection and timely treatment.

Chronic kidney disease is a disease whereby the patient's kidneys progressively lose their capacity to filter wastes and excessive fluids from the blood stream.
Since kidney damage develops slowly, many individuals might not experience any signs in the early stages of the disease. It is therefore critical for individuals to know about the stages of CKD in order to appreciate the significance of kidney monitoring and timely medical intervention.
At stage 1, patients' kidney functions will be relatively normal (eGFR level of 90 or more). However, there will be some indication of kidney damage for example presence of protein in urine. Individuals usually show no symptoms. Controlling diseases like diabetes and high blood pressure can delay progression of CKD.
This CKD stage is indicated by an eGFR level of 60 – 89 as well as kidney damage. There will probably be no symptoms or very mild symptoms at this stage.

This stage reflects the moderate loss of kidney function and features an eGFR ranging from 30-59. It normally involves two sub-stages that can be either 3a or 3b. Some of the symptoms of kidney failure can be fatigue, swelling of legs or ankles, changes in urination, or hypertension.
The fourth stage means that there is a severe loss of kidney functionality, which can be measured by eGFR of 15-29. It normally entails such symptoms as vomiting, swelling, tiredness, or changes in appetite. Health specialists discuss the possibilities of treatment of end-stage kidney disease with their clients and prepare them for getting a new kidney.

Stage 5 is indicated by eGFR being below 15 or the inability of kidneys to perform their functions properly. Waste products and extra fluids can accumulate in the blood and cause life-threatening conditions. Depending on the condition of a patient, the treatments may include dialysis, kidney transplantation, or supportive therapy.
The progression of CKD may not always be swift and early detection can make all the difference. The management of blood pressure and sugar, heeding medical advice, living a healthy lifestyle and regular medical check-ups can help preserve kidney functions. If anyone experiences consistent swelling, alteration in urinary habits or feels unusually tired among other symptoms, they should visit a Nephrologist.
