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.

Women can play a major role in preventing as well as eliminating Chagas Disease, a potentially life-threatening neglected tropical disease that affects 8 million people globally and causes 10,000 deaths every year, according to UN agencies.

World Chagas Disease Day is observed every year on April 14 to raise awareness around the disease, and the impact it has on lives.

In a statement, the Pan American Health Organization (PAHO) and the Global Chagas Coalition urged health authorities to make women central to the fight against the disease and to empower them to make early detection, prevention, and care.

“Eliminating Chagas disease as a public health problem requires placing women at the center of diagnosis, treatment, and care strategies,” said Dr. Jarbas Barbosa, PAHO Director.

“Ensuring timely access to quality health services, particularly for women of reproductive age, is essential to prevent new infections and advance toward the elimination of congenital Chagas disease in the Region of the Americas,” he added.

What Is Chagas Disease?

Chagas disease, also known as American trypanosomiasis, is a illness caused by the parasite Trypanosoma cruzi, and is primarily transmitted by triatomine insect vectors.

It gets spread through

• oral transmission,
• blood transfusion,
• mother-to-child.
• through transplants of some organs (such as heart or kidney)
• through laboratory accidents.

If left untreated, one third of infected people—including women and the children they carry—will develop life-altering heart, digestive, and even neurological conditions, and may even become fatal.

Once endemic to 21 countries in Latin America, the disease has now spread globally due to migration. It is now a global health concern with cases found in 44 countries including the US, Canada, Europe, Australia, and Japan.

World Chagas Disease Day 2026: Theme

World Chagas Disease Day was celebrated for the first time in 2020.

The theme this year is “Women at the heart of care, protecting the next generation” and underscores the key role women play in family and community caregiving, as well as their greater interaction with health services, particularly during pregnancy.

Chagas Disease: Role Of Women

According to the World Health Organization (WHO), about 2 million women aged 15-44 years are living with Trypanosoma cruzi infection worldwide.

Congenital transmission or mother-to-child transmission remains a major challenge, occurring in about 3–5 percent of pregnancies. However, it also provides a key opportunity for effective intervention.

The transmission cycle of the disease can be effectively broken by

• Treating infected girls and women before pregnancy
• Strengthening screening in maternal and child health services
• Eaccess to diagnosis and treatment.
• Newborn screening can help diagnose and treat, with a cure rate exceeding 90 percent.
• Increase awareness at community and family levels.
• Avoid foodborne transmission

“On the contrary, it represents a strategic opportunity to strengthen more equitable, accessible, and responsive health systems that recognize and respect women’s needs.”

The BBC Breakfast host Naga Munchetty has opened up about her experience of suffering from a painful womb condition, known as the "evil twin sister of endometriosis".

The 51-year-old Naga Munchetty explained her condition as adenomyosis, which can cause extreme pain at any time. Munchetty added that she has faced the condition even while presenting her show, The Independent reported.

Naga Munchetty said that adenomyosis has caused her severe pain since she was in her teens, and she has “become conditioned to accept” it.

“If you’re curled up on the floor screaming, sweating, flooding, passing out, vomiting, that is debilitating. But you end up normalizing that pain.”

What Is Adenomyosis

Adenomyosis is an extremely painful condition, which affects the womb and causes the uterus to enlarge. Although it affects an estimated one in 10 women, it remains undiagnosed in most women.

It is a lesser-known but significantly debilitating gynecological disorder that is commonly mistaken for endometriosis.

Adenomyosis leads to debilitating symptoms such as

• intense pain
• heavy menstrual bleeding,
• cramps,
• abdominal bloating
• fertility issues.

Differences Between Endometriosis And Adenomyosis

Adenomyosis occurs when endometrial cells—typically restricted to the lining of the uterus—break through the myometrium, the muscular wall of the uterus.

Endometriosis, on the other hand, happens when tissue similar to the lining of the uterus grows outside the uterus. These tissues commonly develop on the ovaries, fallopian tubes, or the pelvic lining.

In contrast, adenomyosis is inside the uterus but produces serious complications. These out-of-place endometrial cells continue to act as they would in a regular menstrual cycle, becoming thick and shedding, which leads to internal bleeding, inflammation, and intense pain.

Adenomyosis: The Condition Without Treatment

Despite going to the doctors several times, Naga Munchetty was not diagnosed until recently, as she was led to believe the pain she was experiencing was “normal”.

No absolute cure for adenomyosis exists except for a hysterectomy, which involves the removal of the uterus. Nevertheless, several treatment options can alleviate symptoms and enhance quality of life. These include:

1. Pain Relief

Ibuprofen and naproxen, over-the-counter pain medications, are usually prescribed to relieve menstrual cramps and pain.

2. Hormonal treatment such as

• Birth control pills
• Hormonal IUD (Intrauterine Device)
• Progesterone therapy

GnRH agonists, such as Lupron, induce temporary menopause by suppressing estrogen production, thereby reducing adenomyosis symptoms. However, these injections can cause severe side effects, including mood swings, hot flashes, and bone density loss, making them unsuitable for long-term use.

4. Surgical Intervention

• Endometrial Ablation: This involves the removal of the uterine lining to manage heavy bleeding, but it is not a permanent solution and is not suitable for women who want to become pregnant.
• Uterine Artery Embolization (UAE): A non-surgical procedure that cuts off the blood supply to the affected areas, reducing the size of the adenomyotic tissue.
• Hysterectomy: The only permanent solution for adenomyosis, a hysterectomy is usually considered as a last option for women who have finished their childbearing years.

Hypertension, or high blood pressure, is caused by excessive salt intake; however, according to scientists, there are more reasons. Experts also blame a brain glitch. A part of the brain that makes us breathe while laughing or coughing could also cause a blood pressure spike, as per researchers from New Zealand and Brazil. This could explain why medication is not enough for controlling BP in some people. According to experts at the University of Auckland, there is a part of the brain that could cause high BP, thereby suggesting that the brain is responsible for hypertension.

Is the brain responsible for high BP?

Experts say that the lateral parafacial region is located in the brainstem. It is the oldest part of the brain and regulates heart rate, digestion, and breathing. Its action causes one to exhale during a cough, laugh, or workout. These actions are driven by abdominal muscles. Researchers also found that this area could connect to the nerves that tighten blood vessels and raise blood pressure. However, it is possible to reverse this action by inactivating this region.

What is hypertension?

Hypertension, or high blood pressure, is a condition wherein blood pushes against the walls of the blood vessels with too much force. Initially, it has no symptoms, but it is a silent killer. Over time, untreated high BP can lead to a stroke or a heart attack. While it is mostly believed to be a consequence of smoking, drinking alcohol, eating salty foods, and not exercising, experts have found other causes as well. As per research by the University of São Paulo in Brazil and the University of Auckland in New Zealand, published in the journal Circulation Research, rat brains had their brain cells in the lateral parafacial region switched off.

How is high BP triggered by the brain?

Researchers in the study successfully reactivated neurons in some rats and found that brain circuits ultimately raised BP. Experts mapped out what happened and compared it with rats that did not have hypertension. In the hypertensive group, lateral parafacial region neurons were helping with breathing but were also raising BP. This suggests that changes in breathing, which involve abdominal muscle contractions, can also trigger high BP. This is why patients with sleep apnoea experience interrupted breathing while sleeping and high blood pressure.

Apart from normal breathing, lateral parafacial region neurons are activated when oxygen levels are low. Experts also checked whether they could trigger the brainstem with medication. They noted that it was tricky because drugs would work on the entire brain and not a specific region. It could be activated by signals from the neck cells near the carotid artery. These can be safely targeted with medication.

How to control persistent high BP?

To control persistent high BP, medication every day is a must. But to intensify the benefits, try the following simple tricks:

1. Reduce salt intake
2. Meditation
3. Quit smoking
4. Lose weight
5. Limit alcohol intake
