As per the World Health Organization, all but 1% of the world's population is exposed to unhealthy air and also exceeds the WHO limits for pollutants. However, there are some parts of the world where aur quality has improved through policies that limits pollution, while in other parts, it has not reached the desired results.

For US, more than 25% of the population is exposed to "unhealthy" air as per the Environmental Protection Agency (EPA), this is according to the report by the climate non-profit First Street Foundation. By 2050, the number of people exposed to "unhealthy" air will increase by more than half. The worst days of air pollution, reports BBC, "hazardous" or maroon under the EPA's system will rise by 27%.

Why are we talking about this today? It is because of the recent wildfire in California, which started on January 7. This is also one of the factors that is spiking the PM2.5 levels. It has increased by up to five micrograms per cubic metre in the western US in the past decade.

What is PM2.5?

It is a type of air pollution which is made of particulate matter and measures 2.5 micrometres across or less. It is roughly 30 times smaller than the width of a human hair. These particles are made with a mixture of solid and liquid substances, which varies in their chemical composition, including carbon, metals, and organic compounds.

These specks of airborne soot, dust and other substances can also trigger inflammation, which could also damage your brain.

As per a 2021 study titled The Changing risk and burden of wildfire in the United States, a quarter of US's PM2.5 pollution was caused by wildfire smoke. In 2023, US also witnessed a significant dip in air quality and visibility as smoke from wildfires north of the Canadian border entered across the continent. In May 2024, Canada also saw a start to its wildfire season, and one town was evacuated in British Colombia.

Wildfire smoke and its effects

Wildfires do not only affect those who live near forests, peatlands, and grasslands, but also to the cities and environment in general. It can send plumes up to 14 miles or 23km into the stratosphere, and from there, it can spread all over the globe. For instance, in 2023, the Siberian wildfires released smoke that travelled across the Pacific Oceans to reach Alaska and Seattle.

Other than PM2.5, wildfire smoke is also harmful to immune cells in lungs, and the toxicity could be four times greater than particulates from other types of pollution.

Another 2019 study titled Effects of Atmosphere Processing on the Oxidative Potential of Biomass Burning Organic Aerosols found the toxicity of smoke doubled in the hours after it was first emitted and reached four times greater toxicity at its peak.

Health Impact

There have been research that shows how pollution affects your brain. It can lead to impaired judgment, poorer performance in school and even higher levels of crime, as per the 2018 study by the London School of Economics.

Other health concerns include weight gain. There have been researches that links airborne pollution such as PM2.5 to obesity. The studies have found that children who live in most polluted areas are twice as more likely to have obesity. Some studies also find the link of air pollution harming our sense of smell. As per an Italian study from 2022, titled Association between environmental air pollution and olfactory functioning among Italian adolescents and young adults in Northern Italy, noses of teenagers and young adults became less sensitive to odors after being exposed to nitrogen dioxide, which is a component in traffic fumes.

Pregnancy is a period of immense physiological change. While most people focus on visible transformations, the heart and blood vessels undergo some of the most significant adjustments.

The body of a woman increases blood volume by around 30-50 percent to support the growth of the baby. The heart works harder, pumping more blood every minute.

For most of the women, these changes are normal and well-tolerated. In some cases, fluctuations in blood pressure and underlying cardiac risks can pose some serious complications if not identified at an early stage.

Why Blood Pressure Changes During Pregnancy

Blood pressure does not remain the same throughout the pregnancy. In early pregnancy, it often drops slightly due to changes in hormones that relax the blood vessels. By the second and third trimesters, it may gradually rise again as the volume of blood increases. While mild variation is normal, high blood pressure requires careful monitoring.

After 20 weeks of pregnancy, gestational hypertension develops, which can also progress to preeclampsia -- a potentially dangerous condition characterized by high blood pressure, particularly impacting the liver and kidneys. If left untreated, it can also impact both maternal and fetal health.

Understanding Cardiac Risks In Pregnancy

During pregnancy, certain women are at higher risk of heart-related complications. These mainly include diabetes, obesity, thyroid disorders, kidney disease, or a history of heart problems. Even those women who are not suffering from any prior cardiac illness can also develop pregnancy-related heart conditions, such as peripartum cardiomyopathy.

Symptoms that should never be untreated mainly include severe headaches, sudden swelling of hands or face, chest pain, breathlessness at rest, palpitations, or persistent fatigue beyond the expected pregnancy-related tiredness. Certain complications can also be prevented through early medical evaluation.

Some of the symptoms that should never be ignored mainly include severe headaches, sudden swelling of hands or face, chest pain, breathlessness at rest, palpitations, or persistent fatigue beyond expected pregnancy-related tiredness. Early medical evaluation can prevent certain complications.

Impact On The Baby

Flow of blood to the placenta can be reduced through uncontrolled high blood pressure, leading to restricted growth of the fetus, preterm birth, or low birth weight.

Timely medical diagnosis and management significantly reduce these kinds of risks and improve the outcomes as well.

Prevention, Monitoring And Safe Management

Regular antenatal checkups are considered the cornerstone of prevention. Problems can also be detected through monitoring of blood pressure at each and every visit, and appropriate blood tests and ultrasound assessments as well.

Some other factors, such as a balanced diet, controlled salt intake, adequate hydration, moderate physical activity (as advised), and stress management, also play a significant role. With proper supervision and early medical intervention, most women with fluctuations in blood pressure can also have a safe pregnancy and healthy delivery.

Pregnancy is not only about nurturing a new life, but it is also about safeguarding the maternal heart health for the future.

Cervical cancer is still one of the most common cancers for women in India. It's mostly caused by a persistent infection with the Human Papillomavirus, or HPV for short.

This virus spreads through sexual contact and often doesn't show any symptoms early on. A lot of women don't even realize they have the virus until abnormal cell changes start to show up.

The World Health Organization says that cervical cancer is one of the most preventable cancers if people get vaccinated and screened on time.

In India, thousands of women still die every year because they're diagnosed late and don't have enough access to regular screening. That's where the new nationwide HPV vaccination drive is starting to make a difference.

Let’s Talk About The HPV Vaccine

The HPV vaccine basically protects against the types of the virus that are most often linked to cervical cancer. You get it as a shot, and it works best if you get it before you're exposed to the virus, usually when you're a young teenager. But it can still help even if you get it later.

India's really pushing to get this vaccine out there, which is a big change in how they're handling public health. The idea is pretty straightforward and impactful: protect young girls before the virus can do any damage. By focusing on school-aged kids and making sure parents know about it, they're trying to fix a problem that's been around for ages.

Why Is This Drive So Important?

Cervical cancer doesn't just pop up overnight. It usually takes years for an HPV infection to turn into cancer. This long window gives us a chance to prevent it. Vaccination stops the infection at the start, and screening catches early cell changes before they get serious.

Public health experts think that if enough people get vaccinated, we could prevent up to 80,000 cancer deaths in India every year over time. That number isn't just a statistic. It's about saving the lives of mothers, daughters, and sisters with a simple preventive measure.

The vaccine has been studied a lot worldwide and has strong safety and effectiveness data. Countries with high vaccination rates are already seeing big drops in HPV infections and precancerous lesions.

Busting Myths And Building Trust

Even though there's solid science behind vaccines, there's still a lot of wrong info out there. Some parents are concerned about safety or what might happen down the road. Others think getting vaccinated makes kids sexually active sooner, but studies don't back that up.

Getting the facts straight is super important for dealing with these worries. The HPV vaccine doesn't mess with fertility or hormones. It just teaches your body to fight off certain types of the virus.

Getting communities involved, having healthcare pros on board, and running educational campaigns are all crucial for building trust. When families learn that this vaccine can prevent cancer, more people are on board.

Beyond Shots: Screening Matters

Vaccination isn't the only answer. Women who are already sexually active still need regular cervical screening. Pap smears and HPV testing are still super important for catching things early. India's bigger plan includes making screening programs at primary healthcare centers stronger. When vaccination and screening work together, the impact gets way bigger.

Getting Closer To Wiping Out Cancer

The World Health Organization wants to get rid of cervical cancer as a public health issue this century, and India's vaccination plan fits right in with that big goal.

This isn't just about medicine; it's about really caring for women's health and stopping problems before they start. In a country where getting cancer treatment can be tough, prevention is our best bet.

Cervical cancer is mostly preventable. If we keep vaccinating, have good screening, and make sure everyone knows the facts, we could save thousands of lives every year. This campaign is a huge step towards a future where cervical cancer is rare, not something we just expect.

Kenyan-Mexican actress Lupita Nyong’o has revealed that her fibroids have returned after undergoing surgery in 2014 -- now doubling up to 50, raising awareness about the often-overlooked health condition in women.

Speaking at the Today show, the Oscar-winning star Nyong’o said that she was first diagnosed with fibroids, a noncancerous tumor -- about 30 in number -- in 2014.

The growths made of muscle and tissue were removed with myomectomy, the fibroid-removal surgery.

However, the fibroids came back after over a decade, with the largest being the size of an orange, Nyong’o said.

She noted that the doubled-up fibroids are causing her more pain, while her treatment options remain largely the same.

“The first time I got the fibroids taken out, they took out 23,” she said on the show. “And this time, I’ve been informed two years ago that I have over 50.”

“And I’m being faced with the same options,” she added. “Surgery or live with the pain.”

Even as she is contemplating her treatment options, the A Quiet Place: Day One star opened up about feeling left alone and scared for her reproductive health during the initial phase.

She is now speaking out and connecting with other women suffering like her. Nyong’o is also advocating and raising money for scientists to research less invasive and non-invasive treatment methods for fibroids.

I was told that fibroids were something women live with. In refuse to accept that. Millions of women are suffering in silence, and we deserve better answers, better care and better options," Nyong’o wrote in a post on Instagram.

What Are Fibroids

Uterine fibroids are noncancerous growths that form inside or on the uterus. They are very common, affecting an estimated 40 to 80 percent of people with a uterus between the ages of 30 and 50.

In some cases, fibroids do not cause any noticeable symptoms, which means many people may not realize they have them. However, when symptoms are present, they often include:

• Heavy menstrual bleeding or painful periods
• Longer or more frequent periods
• Pelvic pressure or pain
• Frequent urination or trouble urinating
• Growing stomach area
• Constipation
• Pain in the stomach area or lower back, or pain during sex

Obesity and a higher body mass index (BMI) are the most common risk factors that can increase the chances of developing fibroids. Others include family history, not having children, early onset of menstruation (getting your period at a young age), and late age of menopause.

How To Treat Fibroids? Can They Recur?

There are several tests that can be done to confirm fibroids and determine their size and location.

These tests can include ultrasonography, magnetic resonance imaging (MRI), computed tomography (CT) scan, hysteroscopy, and laparoscopy.

Myomectomy is a commonly used surgical procedure to remove fibroids. There are several types of myomectomy, and they are used depending on the location of the fibroids, their size, and number.

The types of myomectomy procedures include hysteroscopy, laparoscopy, laparotomy, hysterectomy, uterine fibroid embolization, and radiofrequency ablation (RFA).

Even after a successful myomectomy, new fibroids can still develop. The recurrence risk is more common among young adults (under age 40) with many fibroids. The risk is less among people near menopause or with few fibroids.

Visit your doctor if you have:

• Pelvic pain that doesn't go away
• Heavy or painful periods that limit what you can do
• Spotting or bleeding between periods
• Trouble emptying your bladder
• Ongoing tiredness and weakness, which can be symptoms of anemia, meaning a low level of red blood cells.
