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.
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.
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.
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.

Supreme Court on Friday declared the right to menstrual health as part of the right to life under Article 21 of the Constitution. The court issued a slew of directions to ensure that every school provides biodegradable sanitary napkins free of cost to adolescent girls. The guidelines also ensured that schools must be equipped with functional and hygienic gender-segregated toilets. The Court directed the pan-India implementation of the Union's national policy, 'Menstrual Hygiene Policy for School-going Girls' in schools for adolescent girl children from Classes 6-12.

A bench comprising Justice JB Pardiwala and Justice R Mahadevan passed the following directions:
The court also issued directions for the disposal of sanitary waste. Justice Pardiwala said, "This pronouncement is not just for stakeholders of the legal system. It is also meant for classrooms where girls hesitate to ask for help. It is for teachers who want to help but are restrained due to a lack of resources. And it is for parents who may not realise the impact of their silence and for society to establish its progress as a measure in how we protect the most vulnerable. We wish to communicate to every girlchild who may have become a victim of absenteeism because her body was perceived as a burden when the fault is not hers."

In India, menstruation is still seen as taboo. In fact, there is a lot of shame around it. Menstrual shame is the deeply internalized stigma, embarrassment, and negative perception surrounding menstruation, which causes individuals to feel unclean, or "less than" for a natural biological process. This judgment thus is an effort to do away with the shame rooted in cultural, social, and religious taboos, which is often the reason why many girls drop out, or due to lack of awareness, develop health adversities.

Most health videos on YouTube, even those made by doctors are also not reliable medical information, found a new study, published in JAMA Network Open. The researchers reviewed 309 popular YouTube videos on cancer and diabetes and found that fewer than 1 in 5 were supported by high quality scientific evidence. About two-thirds of the view had low, very low or no evidence at all to back up their health claims.
What was more concerning is that weaker evidence often attracted more viewer than those backed with strong science. The study looked at videos which had at least 10,000 views. The lead author of the study Dr EunKyo Kang of South Korea's National Cancer Center, said, "This reveals a substantial credibility-evidence gap in medical content videos, where physician authority frequently legitimizes claims lacking robust empirical support."
"Our findings underscore the necessity for evidence-based content-creation guidelines, enhanced science communication training for health care professionals, and algorithmic reforms prioritizing scientific rigor alongside engagement metrics," Kang added in a news release.
The researchers reviewed videos from June 20 and 21, 2025, focusing on cancer and diabetes content. 75 per cent of them were made by physicians. The videos had a median count of 164,000 views and a median length of 19 minutes.
Researchers also developed a scoring system, called E-GRADE to rate the strength of science backed evidence in each video's claim.
The study also found that videos with the weakest evidence were 35% more likely to get higher views than videos with strong scientific evidence.
Richard Saver, a professor of law at the University of North Carolina at Chapel Hill noted that this issue is not just limited to YouTube. "Physician-spread misinformation is a long-standing problem, dating back well before the internet era," he wrote in an accompanying editorial.
Saver said some doctors continue to lean on personal experience rather than solid data, despite evidence-based medicine being regarded as the gold standard. He noted that EBM can feel like it downplays individual clinical judgment. Still, Saver stressed that more research is needed, adding that the study underscores the importance of examining the evidence behind health professionals’ claims on social media.
Health and Me has always stayed a step ahead from medical misinformation and ensured that its readers too consume correct information. Health and Me's Fact Check series have consistently ran checks on bizarre medical claims, whether it is about a magical potion for weight loss, fake health news, or un-scientific remedies.

The World Health Organization (WHO) noted that menopause often goes unnoticed as a clinical priority, observing these unmet needs, the state governments in Maharashtra and Kerala will soon launch government-run menopause clinics. These clinics will have specialized support systems designed to offer holistic healthcare services for menopausal women within the public system.
These clinics will also have medical consultations, mental health counselling, targeted screening services and lifestyle guidance.
Menopause clinics are specialized healthcare units, usually housed in government hospitals, urban health centres or district hospitals, that focus on both the medical and emotional needs of women transitioning through menopause. Rather than brushing menopause aside as a “natural” phase that needs little attention, these clinics offer organized, evidence-based care that goes well beyond routine outpatient visits.
At the heart of a menopause clinic is a comprehensive, integrated approach that includes:
By bringing these services together under one roof, menopause clinics help women cope with day-to-day symptoms while also addressing long-term risks like osteoporosis, metabolic changes and a higher likelihood of cardiovascular disease.
This is the natural, permanent end of menstruation defined as 12 consecutive months without a period. This typically occurs between ages 45 to 55.
Including these foods in your diet could help ease symptoms and reduce your risk of certain menopause-related conditions.
A nutrient-packed, balanced diet is the foundation of good health at any age. Prioritize:
Earlier this January, the Maharashtra government rolled out the country’s first state-run menopause clinics across government hospitals and urban health facilities. The initiative was launched on Makar Sankranti, January 14, under the guidance of Minister of State for Health Meghna Bordikar.
As per official statements, these clinics are designed to offer end-to-end care in one place. Services include expert medical consultations to evaluate and manage menopausal symptoms, mental health support to address emotional and psychological concerns, and screenings for bone health, cardiovascular risk and hormonal balance. Medicines and follow-up advice are also provided during the same visit, cutting down the need for multiple referrals and repeat hospital trips.
A senior health official pointed out that while menopause is a natural life stage and not a disease, many women need consistent physical and emotional support during this transition. The strong response from women across Maharashtra highlights a long-standing gap in healthcare, where menopause-related concerns often went unaddressed due to the absence of dedicated services. With this move, Maharashtra has also set an example for other states looking to introduce gender-specific care within public health systems.

Taking a cue from Maharashtra, the Kerala government has announced plans to set up specialized menopause clinics in district hospitals. An initial allocation of Rs 3 crore has been earmarked for the project in the 2026 state budget, presented by Finance Minister K N Balagopal.
The proposed clinics in Kerala will follow a similar model, offering medical consultations for menopausal symptoms, mental health counselling, and screenings for heart, bone and hormonal health. Women will also receive medicines along with lifestyle and dietary advice at a single facility.
The initiative acknowledges the wide-ranging impact of menopause, including hormonal changes, sleep disturbances, bone health issues and increased stress, and aims to create a one-stop support system within district hospitals. By bringing menopause care into mainstream public healthcare, Kerala hopes to improve access, reduce stigma and ensure that women receive timely, structured support during this phase of life.
