A report by Swachh Bharat Mission says that 74.5 per cent of public places are equipped with toilets. Another report by the Ministry of Jal Shakti states that there are 2.23 lakh Community Sanitary Complexes built across all States and UTs under the Swachh Bharat Mission (SBM) since October 2014. Over 92 lakh toilets have been constructed since the launch of SBM Gramin (SBM (G)) in April 2020.

While toilets are there, are they accessible? This is the question one should ask. The National Family Health Survey (NFHS) focuses on 131 health indicators, but not until the NFHS 5 survey did they include the question of accessibility of toilets in the survey. This happened after the inputs from the Department of Drinking Water and Sanitation (DDWS) and the Ministry of Health & Family Welfare questioned the accessibility.

One might ask, why is the question of accessibility so important? The answer is quite simple. Access to water, sanitation and hygiene is the most basic human need and is also included under the Sustainable Development Goals by the UN.

Are These Numbers Real?

This thought crossed my mind because back in 2021, I went on a solo trip, on a bus to Udaipur from Delhi. There, the bus made two stoppages. This was done so people could get a quick dinner and freshen up, relieve themselves and be prepared for the rest of the journey. This was a nightmare. The bus only stopped for 10 minutes. While some men used the washroom, others went to the bushes.

For the women, there were three cubicles. One of them was broken, and the other one did not have a light bulb, which meant only one was usable. There was a long queue for that cubicle, and time was short. There was no point in trying to find an isolated corner, because it was past midnight, in an unknown area.

I waited anxiously. When finally, my turn came, I saw an overused, dirty washroom. The toilet seat is in a horrible condition. I wanted to touch nothing there. But I had to pee. So, I used my mask to cover my nose from the odour, folded my pants so they did not touch the floor and squatted. It was quite a task to balance.

On my way back to Delhi, I made sure to not drink any water for over a 13-hour bus journey. I dehydrated myself so I did not have to use the washroom. When I did reach, I was severely dehydrated and was sick for three days.

I shared my experience with my friends only to realise that many women have faced the same. There are no washrooms for women.

A friend of mine told me that it is because these roads and dhabas are mainly designed to serve men. They are the ones who travel at night or are on the roads most of the time. As a result, the few women who do travel or are on the road suffer.

Health Risks Women Are Prone To

Well, it is true, but partially. While holding your pee for too long can lead to health risks, peeing on a dirty toilet seat cannot lead to infections unless your urethra is in contact with the bacteria present on that toilet seat. However, nobody wants to sit on a dirty toilet seat, even if you do not get an infection. A safe and hygienic toilet is a basic need.

One of the regular saleswomen, Usha, who visits my house shared her experience with me. “Being on the road constantly means I must use the dirty public washrooms. But I do not want to use them. So, sometimes I ask my regular customers to let me use their washrooms. Some say yes, and some say no. I understand they are also concerned about their safety and privacy,” she says. As a result, Usha spends most of her day not drinking enough water and holding her pee when she is at work. Due to this, she also suffered from a Urinary Tract Infection (UTI).

Her friend, Halima too faced similar problems and due to increased levels of uric acid in her body, she suffered from Hyperuricemia.

Other health risks are kidney stones and other kidney problems, headaches, dull skin, xerostomia or dry mouth, fatigue, and urinary incontinence, which means losing control over your pelvic floor muscles leading to uncontrolled leakage of urine, seizures and weakness.

What Can You Do?

Wear comfortable clothes and capris. Capri pants are comfortable and are short in length, which means this won’t touch the toilet floor when you squat or sit.

Carry Essentials

Even though you cannot get a UTI alone from sitting on a toilet seat, it is always safe to carry a toilet seat sanitiser. If nothing, it can help you get rid of the bad odour so you can use your stand and pee device inside the toilet. You can also use disposable toilet seat covers if your knees are weak, and you cannot squat. Always flush with your seat down.

Always keep disposable gloves, a portable bidet (fill it with water before use), a pocket liquid handwash, wet wipes, tissues and sanitiser handy. Do not forget to keep extra sanitary pads. It might sound a lot, but I promise that it all fits in one pouch. Use this travel-friendly pouch every time you are on the road, or using a public washroom.

What Can We Learn From Others?

However, in case we do not get these technologically advanced toilets here, you can always pack a travel-friendly toilet kit!

After Dussehra festivities, Delhi woke up to an alarming AQI of 300, maybe even more in some parts of the city. On October 21, pollution curbs under GRAP-1 were implemented, which are brought in force when AQI ranges between 201 and 300.

As Delhi's air pollution increases, some people may experience uncommon symptoms like feeling unusually tired, sluggish or unable to concentrate. This is not just a coincidence. Even people without asthma or breathing difficulties can feel fatigue, especially during periods of high air pollution.

Fine particulate matter (PM2.5) can penetrate deep into the lungs and trigger inflammation and physiological stress. Its effects may extend beyond the respiratory system, affecting blood vessels health, cardiovascular function as well as sleep.

HeathandMe spoke to Dr Puneet Khanna, Chairman, Respiratory Medicine and Pulmonology, Manipal Hospital Dwarka, New Delhi, Dr. Puneet Gupta, HOD - Pulmonology, Intervention Pulmonology & Sleep Medicine, Yatharth Super Speciality Hospital, Noida Extension, and Dr Mrinal Sircar, Director, Respiratory and Sleep Medicine, Medanta, Noida, who explained why rising AQI can leave some people feeling exhausted, what can help and when chronic fatigue needs medical attention.

High AQI May Make You Feel Tired Even Without Breathing Problems

Poor air quality does not affect just the lungs. Dr Sircar explains that air pollution can cause symptoms even in people without a pre-existing respiratory condition.

According to Dr Khanna, exposure to PM2.5 can trigger inflammation and oxidative stress, increase the body's workload and affect sleep quality. These changes may contribute to tiredness, headaches, low energy and reduced concentration, even in people with otherwise healthy lungs.

“Exposure to polluted air may also affect sleep quality and increase the body's overall stress response, contributing to symptoms such as tiredness, reduced energy and difficulty concentrating,” he says.

Dr. Gupta delves deeper into the process of PM2.5's attack and how the body responds to it.

He explained, "Your immune system treats fine particles (PM2.5) as intruders and mounts a constant low-grade defence, which burns energy much like a mild infection. At the same time, irritated airways and gases like carbon monoxide can make oxygen delivery slightly less efficient. The most underrated cause is sleep: a dry throat, blocked nose, and mild night-time cough fragment your sleep, so you wake up unrefreshed without knowing why. Fatigue here doesn’t mean your lungs are weak. It means your body is working overtime quietly."

Can PM2.5 Affect The Heart And Blood Vessels Too?

PM2.5 particles are small enough to penetrate deep into the lungs. Some of its components can even enter the bloodstream. Exposure can trigger inflammatory and oxidative stress responses beyond the respiratory system.

Dr Khanna says, “These changes may reduce physical endurance, increase feelings of fatigue, and contribute to symptoms such as brain fog, lethargy, and reduced exercise tolerance, particularly during periods of severe air pollution.”

Dr. Gupta explained PM2.5 can create the same response from body as a common flu does. But the extent of these effects depends on pollution levels, duration of exposure and individual risk.

He said, "PM2.5 is small enough that it, or the inflammatory chemicals it triggers, can enter the bloodstream. Signalling molecules such as IL-6 and CRP then travel through the whole body and produce the same “wiped out” feeling you get with the flu."

He also said that particles also create oxidative stress, which damages mitochondria, the power plants of your cells. Blood vessels become stiffer, blood pressure can rise slightly, and the nervous system’s control of heart rhythm can be disturbed, which may feel like heaviness or palpitations. Inflammation can also reach the brain, causing fog and poor focus.

What Can Help?

According to the doctors, the key is to reduce exposure to polluted air. Practical steps include:

• Limit exertion: Avoid strenuous outdoor activity when pollution levels are high, especially during periods of severe pollution.
• Wear a well-fitting N95 respirator: It can reduce exposure to fine particles when outdoors.
• Improve indoor air quality: Keep windows closed when outdoor air quality is poor and use a suitably sized air purifier with a HEPA filter where feasible.
• Maintain basic health routines: Get adequate sleep, stay hydrated and eat regular meals.
• Check AQI levels: Use local air quality updates to plan outdoor activities.

Dr Khanna emphasises that these steps can help reduce exposure but cannot eliminate the effects of ongoing pollution. He also said that severe breathlessness, chest pain, fainting or sudden weakness requires urgent medical attention.

Does Pollution-Induced Fatigue Go Away When AQI Improves?

For many otherwise healthy people, symptoms can improve once air quality improves. Dr Khanna says recovery may occur within a few hours to several days, depending on pollution severity, exposure duration and individual health.

However, there is no fixed recovery timeline. People with underlying respiratory or cardiovascular conditions may take longer to recover, while persistent tiredness may point to another health problem.

Dr Sircar advises seeking medical advice if fatigue continues after air quality improves.

The doctors also advise that if fatigue is chronic, recurrent, worsening or interferes with daily activities, medical evaluation should be sought rather than simply attributing it to air pollution.

Dr Sircar also says that that a doctor may need to investigate other possible causes, including anaemia, thyroid disorders, sleep problems and cardiovascular conditions. Fatigue accompanied by a chronic cough, wheezing, breathlessness, chest problems or reduced exercise tolerance also needs intervention.

A single photograph of someone’s face might carry real clues about their health and how long they’re likely to live, at least according to new AI tools built by researchers at Mass General Brigham in Boston.

What the researchers built

The team trained a large AI foundation model called FAHR-Face, short for Foundation Artificial Intelligence for Health Recognition, on more than 40 million facial images.

From that base model, they built two specialised tools: FAHR-FaceAge, which estimates a person’s biological age from a single photo, and FAHR-FaceSurvival, fine-tuned on 34,389 photos of cancer patients to predict survival risk directly from facial appearance.

“I was pretty surprised to find out that we could pick up signs of mortality risk from just a facial photograph,” corresponding author is Dr. Raymond Mak, a radiation oncologist at Mass General Brigham Cancer Institute told CNN. The study is published in The Lancet Digital Health.

What the two tools actually look at

The two algorithms focus on entirely different parts of the face. “The age estimation algorithm is looking at the area around the temples, the area on the forehead, above the eyes and then what we call the nasolabial fold,” Mak said, while “the mortality risk prediction algorithm is looking at a totally different part of the face... the bridge of the nose and the area under the eyes.”

The results

Among 122 cancer patients flagged by FAHR-FaceSurvival as high-risk, 52.5% died within 90 days, compared with about 2% of the 975 patients in the lowest-risk group. Separately, 21% of patients whose biological age came back more than 20 years older than their actual age died within 90 days, against about 6% of those whose biological age was at least 10 years younger than their chronological age.

The researchers also found that cosmetic changes, including surgery, Botox, or makeup, didn’t throw off the models’ performance, according to the Mass General Brigham release.

An eerie echo of ancient medicine

The facial regions both AI models rely on, the nose, temples, and the area around the eyes, closely match what the Greek physician Hippocrates described around 400 BC in his Book of Prognostics as signs of approaching death: “the nose sharp, the eyes sunken, the temples fallen in.”

Mak told CNN the algorithms had no exposure to Hippocrates’ text and were trained purely on photographs and outcomes data. “Hearing Hippocrates echo over millennia in our algorithms was very eerie,” he said.

Not ready for the clinic yet

Outside experts urged caution. Dr. Wilbur Lam of Emory University, who wasn’t involved in the study, called it “an extremely compelling study” with robust associations, but said its “true clinical utility... will need to be demonstrated prospectively,” and flagged open questions about how well it performs across different facial features, skin tones, and age groups.

Miroslaw Bober of the University of Surrey, also not involved in the study, said the findings shows “convincing evidence” of a statistical link but cautioned that “predicting an outcome is not the same as explaining it.”

He noted the study never tested whether the AI model picks up anything a doctor’s own assessment wouldn’t, since doctors’ general health evaluations weren’t measured for comparison. “This is a promising proof of concept, but it is not ready for clinical use,” Bober said.

An individual's income, education, gender and place of residence can impact their risk of developing chronic diseases, as well as their access to diagnosis and treatment, according to a new World Health Organization (WHO) report.

The report highlights how social and economic inequalities affect the burden of noncommunicable diseases (NCDs) like cancer, cardiovascular diseases, diabetes and chronic respiratory diseases.

Published on October 20, State of Inequality: Noncommunicable Diseases and Their Risk Factors is WHO's first comprehensive global assessment of inequalities in NCDs and their risk factors. The report is based on data sources from nine countries and examines 35 indicators, using national data that collected over the past decade.

NCDs account for about three-quarters of deaths worldwide but their impact is not shared equally across different countries and their populations. The report examines how differences in economic status, education, sex, age, disability, employment, migration status and location influence disease risks and access to healthcare.

“This is the first effort to systematically measure inequalities in NCDs and their risk factors on a global scale,” said Dr Ahmad Reza Hosseinpoor, who leads WHO's health inequality monitoring team. “The findings show which populations are being left behind.”

How Income And Education Influence Chronic Disease Risk

The report found that people with lower levels of education in low and middle income countries tend to have higher rates of hypertension and diabetes.

Education can affect access to credible health information, opportunities to make informed health decisions and the capability to navigate technically complex healthcare services.

Income becomes a key factor that affects whether people's ability to afford nutritious food, preventive care, medicines and routine medical check-ups.

The report found that the poorest and least-educated women were less likely to receive cervical cancer screening. Tobacco use was also higher among men who were less educated than their educated counterparts.

Risk Is Also Affected By Gender And Location

Differences in healthcare access and risks were also observed between men and women. Men were more likely to use tobacco and consume alcohol, but men with hypertension were less likely to be diagnosed and treated than women.

Women were less likely to meet recommended physical activity levels, while obesity was more common among women, particularly in low and middle-income countries.

Geography was another key factor as in many underprivileged countries, people living in rural areas had less access to hypertension diagnosis and treatment, as well as cervical cancer screening.

Rural households could also face greater exposure to household air pollution, while urban populations often experienced greater exposure to outdoor air pollution.

People with disabilities and migrants may also face financial, administrative, geographical or language barriers that make prevention, screening and treatment harder to access.

What Needs To Change According To WHO

WHO said countries should use inequality data to identify marginalised populations who face barriers to enable direct prevention and treatment services towards them.

The report recommends expanding interventions to reduce NCD risks, improving access to screening and treatment in weak communities, and collecting data that reveal differences between population groups.

“Inequality data are not simply about documenting differences – they are a tool for action,” said Dr Alain Labrique, director of WHO's Data, Digital Health, Analytics and AI Department. “They help countries better tailor policies and programmes, identify gaps in coverage and track whether progress is reaching all population groups.”
