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.

How Does Your Body Respond To Noise?

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.

Hidden Health Risks

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.

Noise and Sleep: A Silent Disturbance

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.

The Urbanization Problem

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.

What Can We Do About It?

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.

A visit to the emergency ward (ER) of a hospital can definitely feel scary, and you want every reason to avoid ending up there as a patient. From broken bones to life-threatening emergencies, it’s a place filled with urgency, uncertainty, and intense emotions. Imagine what doctors and other health workers face every day.

However, while many cases are unavoidable, there are several that can be completely prevented, said doctors, while sharing a few. These include:

• Symptoms ignored for long

However, ignoring symptoms like a persistent stomachache or a nagging cough can allow a condition to worsen over time, eventually leading to an emergency.

“People say, ‘It’s pretty mild. I’m not worried about it,’” Dr. Evelyn Huang, an emergency-room physician with Orlando Health, was quoted as saying to Time.

“Days become weeks, weeks become months, and months can even become years, and by the time they're seeing me, these things have progressed so far that they’re now something dangerous.”

Seeking timely medical advice and not delaying checkups can help prevent complications and avoid unnecessary ER visits, the expert said.

• Drowning

Dr. Cheyenne Falat, assistant medical director of the adult emergency department at University of Maryland Medical Center stated that every time a patient comes ER with a drowning case, he hears the same story.

“I would have been watching them, but I thought the babysitter was watching them. I thought my spouse was watching them. I thought their grandparents were watching them.”

The doctor recommended instead starting swimming lessons as early as possible. She also urged for fences with childproof gates near pools.

• Falling

• Frostbite and hypothermia

People often don’t realize how quickly conditions can turn.

“They think, ‘I won’t be at risk for hypothermia because it's a little warmer during the day,’” said Falat. “Then they sweat,” which can leave their clothing damp and their bodies more vulnerable once temperatures drop.

Heat-related illnesses include mild dehydration to heat exhaustion and, in the most extreme cases, heat stroke, which can be deadly.

• Choking during sex

Recently, for example, he treated a young woman who came to the ER with neck pain, a hoarse voice, and bruising; she assured Yoo that she had wanted her partner to choke her. “I’m not judging anyone who enjoys this, but it's way more dangerous than people think,” he said.

• Party drug

A harmless party drug -- gamma-hydroxybutyric acid, or GHB -- can also turn life-threatening. It is a clear, odorless substance sometimes called “liquid ecstasy.”

While in small amounts, it can make people feel relaxed or euphoric, but when taken in overdose, it can lead to unconscious and breathing difficulties. “It’s one of the most awful sights,” Yoo said , adding that in severe cases, some patients need to be put on a ventilator to survive.

In today’s hyper-connected world, access to health information has never been easier. Yet, ironically, the ability to understand and apply that information remains one of the biggest barriers to better health outcomes.

This is where health literacy comes in, not just the ability to read a pamphlet or follow a doctor’s prescription, but the broader skill of accessing, comprehending, and using health information to make informed decisions for oneself, one’s family, and one’s community.

While definitions vary, there is consensus that health literacy is multi-dimensional. It involves confidence, critical thinking, and practical skills, knowing when to seek care, how to evaluate health claims, and how to follow treatment correctly. In essence, health literacy is the foundation of preventive care and treatment adherence, and its absence can be devastating.

The Challenge of Low Health Literacy in India

The scale of the problem in India is stark: nearly 90 percent of Indians have low health literacy. This gap directly affects patient outcomes, from delayed diagnoses and poor compliance with treatment to preventable complications and higher healthcare costs.

Several factors explain this reality:

• Low literacy levels: A significant proportion of the population cannot read or interpret basic medical instructions, leading to mismanagement of conditions.

• Poverty and affordability: For millions living on less than INR 100 a day, awareness alone is not enough when healthy choices remain unaffordable.

• Gender and cultural barriers: Women often have lower access to information and autonomy in health decisions, particularly around reproductive and maternal health.

• Distrust in healthcare systems: Overcrowded facilities and inconsistent care erode confidence, driving many to informal or unverified sources.

Low health literacy doesn’t just harm individuals; it amplifies inequities and strains the entire healthcare ecosystem. It also worsens misinformation, as people turn to social media or word-of-mouth for guidance, often encountering unverified or unsafe advice.

Planning for pregnancy is an important step that requires proper health preparation for both partners. Preconception health screening helps couples understand fertility status and detect any underlying health issues. Doctors recommend that couples undergo certain medical tests before trying to conceive so that any health concerns can be identified and managed early. Here are some of the tests before pregnancy that can help couples identify potential risks early and improve the chances of a healthy pregnancy. Couples should opt for these tests without fail to ensure a smooth pregnancy.

While many people focus on health during pregnancy, preparing for pregnancy is also equally important. By opting for some crucial tests, couples can improve their chances of a smooth pregnancy and reduce the risk of complications.

Dr. Payal Narang, Consultant Obstetrician & Gynaecologist, Motherhood Hospital, Lullanagar, in an interview with Health and Me, listed some of the important health check-ups for men and women that must be considered before pregnancy.

Important tests for women

1. Infection screening: The expert can advise screening for infections such as rubella, hepatitis B, and HIV that can affect pregnancy or the baby’s health. Hormone tests help assess ovulation and reproductive health. These tests may help detect conditions such as polycystic ovary syndrome (PCOS) or hormonal imbalance. Tests such as anti-Müllerian hormone (AMH), follicle-stimulating hormone (FSH), and luteinizing hormone (LH) may be advised to evaluate ovarian reserve and fertility potential.
2. Pelvic ultrasound: Will be carried out to examine the uterus and ovaries to identify conditions such as fibroids, ovarian cysts, or structural abnormalities. It can also help in detecting abnormalities, endometriosis, or polycystic ovaries that may impact fertility.
3. Complete blood count: Complete blood count (CBC) will help to detect anemia, infections, and your body’s overall readiness. Low hemoglobin is common in Indian women and can lead to fatigue. Treating anemia before pregnancy is important, as low haemoglobin levels can increase the risk of complications during pregnancy and delivery.
4. Rubella IgG Antibody Test: Did you know? Rubella infection during pregnancy can raise the chances of serious birth defects. This test shows if you’re already immune or if you need a vaccine before trying to conceive and prevents any problems.
5. Blood Group and Rh Factor: Should be done to ensure safe pregnancy. If a woman is Rh-negative and her partner is Rh-positive, the expert will examine further to prevent immune-related issues during pregnancy. So, discuss this with the doctor.
6. Vitamin D and B12 screening: Vitamin D and B12 screening shouldn’t be missed: Vitamin D and B12 deficiencies are common in women and can impact fertility, egg health, and fetal development. The expert will suggest supplements to deal with these deficiencies and stay healthy.
7. Blood sugar and HbA1c testing: Screening for diabetes or prediabetes is important before pregnancy, as uncontrolled blood sugar levels can increase the risk of miscarriage, congenital abnormalities, and pregnancy complications.

Health check-ups for men

1. Semen analysis is necessary for men: Helps to know the sperm count, movement, and quality. It helps determine whether sperm health is adequate for successful conception. Men don’t hesitate and get the semen analysis done on a priority basis.
2. Hormone tests: Hormone levels such as testosterone may be checked if there are concerns about fertility or low sperm production. Tests for follicle-stimulating hormone (FSH), luteinizing hormone (LH), and prolactin may also be recommended in certain cases.
3. Genetic Testing: Can be done to pick up any genetic factors or chromosomal abnormalities that may affect sperm quality. Carrier screening can help detect inherited genetic conditions such as thalassemia or cystic fibrosis that may be passed on to the baby.

Couples should follow the advice given by the doctor and take these tests for a smooth pregnancy.
