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!

Climate change is not just raising temperatures and intensifying extreme weather. It may also affect digestive health by disrupting food production, threatening water security and changing the spread of gastrointestinal infections, according to two leading gastroenterology experts from the World Gastroenterology Organization (WGO).

Climate change can contribute to heat-related illnesses and influence the geographic spread of infectious diseases, especially in countries like India.

A February 2025 review in The Lancet Planetary Health outlines how the combined effects of climate change could affect the human gut microbiome, including through food insecurity, malnutrition and exposure to disease-causing pathogens. These challenges could alter the composition of gut microbial communities worldwide.

Research suggests that heat stress may alter gut microbes, digestion and immune function. It may also increase intestinal permeability, potentially allowing toxins and pathogens to enter the bloodstream.

Climate-related drought can disrupt food production and reduce access to nutritious food, potentially affecting the gut microbiome. Environmental changes may also influence food- and waterborne pathogens, increasing infection risks where access to safe water and sanitation is limited.

Speaking to HealthandMe, Professor Geoffrey Metz, professor of medicine at the University of Melbourne, said climate change was becoming an increasing concern for gastrointestinal health.

“Certainly, with global warming, we're seeing a lot more infectious diseases in the gastrointestinal tract,” Metz said.

Climate change can affect digestive health through several interconnected pathways, including water availability, food production and infectious diseases.

Metz said the consequences of global warming extend beyond rising temperatures.

“The other thing, of course, with global warming—and this is a major interest of the World Gastroenterology Organisation—is that it's not just making us hot, but it's also creating more drought, which interacts with food production. So there's less food available, impacting our nutrition.”

Drought can disrupt food production and reduce food availability, raising concerns about nutrition. Changes in water availability can also make safe food preparation and hygiene more difficult.

However, the extent to which these environmental changes contribute to specific gastrointestinal diseases requires further investigation.

Safe Water And Food Hygiene Remain Essential

Professor Carolina Olano, professor of gastroenterology in Montevideo, Uruguay, and president of the WGO, highlighted the role of environmental factors in digestive diseases.

“Well, I think it's a combination of many factors. You know that there are some things related to genetics, and we have genetic predispositions to some diseases. But there are also environmental factors related to different diseases, and climate change has an impact too. We are working very hard at the World Gastroenterology Organisation to understand how climate change is affecting different diseases.”

Olano also emphasised the importance of safe drinking water and food hygiene in preventing infections.

“It's also important to have a varied diet and to drink safe, clean water, making sure that the water we drink is safe. Food hygiene is also extremely important.”

She told HealthandMe that handwashing was another simple preventive measure.

“We learned from the COVID pandemic that handwashing before eating is extremely important. These are things we can do every day without spending anything, and they can help prevent many important diseases, especially those related to infections.”

The effects of climate change may extend beyond the digestive system, affecting multiple aspects of health.

“Global warming is not just affecting how we feel; it's also having an effect on heart disease, lung disease, gastrointestinal disease, obstetrics and gynaecology,” said Metz, who is also the former president of the WGO.

Olano also pointed to population movements as a factor to consider when assessing environmental and health risks.

“As you know, it's not only about weather and climate change. It's also about how populations move from one country to another and what the impact of these movements is when people move from one region to another.”

“Because, as you know, it's not only about weather and climate change. It's also how populations move from one country to another and what the impact of these movements is when people move from one region to another.”

Understanding these connections is important as researchers investigate how climate-related environmental changes may influence disease patterns across regions.

What Can People Do To Protect Their Digestive Health?

While individuals cannot control climate-related changes, Olano highlighted everyday measures that can help prevent infections and support digestive health:

• Drink safe, clean water.
• Maintain food hygiene and handle food safely.
• Wash hands before eating.
• Follow a varied diet.
• Stay physically active.

She also stressed the importance of seeking medical advice about hepatitis prevention, vaccination and testing where appropriate, as well as colorectal cancer screening.

Climate change presents a broader public health challenge, but safe water, food hygiene and infection prevention remain important measures for reducing avoidable digestive health risks.

Depression affects millions of people worldwide, but not everyone responds equally well to treatment. Now, researchers at the University of Sydney have identified a new subtype called “circadian depression,” which is linked to the body’s internal clock and may help explain why conventional antidepressants work less well for some people.

The subtype was identified in nearly a quarter of participants with severe, recurrent or persistent depression in an Australian study. Researchers say recognizing its characteristics could help clinicians identify patients who may benefit from different treatment approaches.

“Our research has identified circadian depression as a new subtype, affecting around a quarter of people in our study into those with severe, recurrent or persistent depression,” said Dr. Emiliana Tonini from the Brain and Mind Centre at the University of Sydney.

“Depression is not a uniform illness and understanding the characteristics of different subtypes mean that we can give people earlier access to treatments that will be most effective for them,” she added.

Circadian Depression: What Are The Key Symptoms?

Circadian depression is linked to the body’s 24-hour internal clock, which regulates the sleep-wake cycle. Researchers identified several symptoms and characteristics associated with this subtype, including:

• A seasonal pattern of illness

• Sleeping longer during depressive episodes

• Waking up feeling very tired

• Being a night owl

To investigate the subtype, researchers analyzed clinical and genetic data from more than 10,000 people with depression who participated in the nationwide Australian Genetics of Depression Study.

Of these, 2,604 participants, or nearly 25%, were identified as having circadian depression.

The researchers also found that people with this subtype were more likely to experience depression earlier in life and had more severe symptoms, including mania and higher levels of suicidal thoughts.

In addition, these participants had a higher genetic risk for inflammatory and cardiovascular health problems, as well as major neurodevelopmental disorders, including attention-deficit/hyperactivity disorder (ADHD).

The findings, published in the British Journal of Psychiatry, offer insights into the genetic mechanisms associated with circadian depression and may help explain why conventional treatments, such as selective serotonin reuptake inhibitors (SSRIs), work less well for some people with this subtype.

How Does Circadian Depression Differ In Treatment Response?

Antidepressants such as SSRIs and serotonin-norepinephrine reuptake inhibitors (SNRIs) are commonly used to treat depression. However, the researchers reported that these medications were less effective and associated with more side effects in people with the circadian subtype.

Because circadian depression is linked to the body’s internal clock, treatments targeting circadian rhythms may be relevant for some patients. These include light therapy, melatonin and melatonin-targeted antidepressants.

“Because circadian depression is linked to people’s internal body clock, treatments targeting the circadian rhythm, such as light therapy and melatonin, may be much more relevant, and clinicians should reach for these much earlier in people with this presentation,” said Dr. Jacob Crouse, co-senior author of the study, from the Brain and Mind Centre.

“For those who find that antidepressants are not working for them, it is important to speak to your clinician for advice about your individual circumstances,” he added.

Professor Ian Hickie, co-director of the Brain and Mind Centre and a clinical psychiatrist, emphasized that failing to recognize circadian depression in young people could contribute to early treatment failures and more side effects.

“We really want young people to receive the most appropriate treatment early in their course of illness.

“Most young people will be offered SSRIs first up, but for at least a quarter there are better circadian-focused medical and behavioural options to help treat and manage their condition.”

The findings suggest that identifying circadian depression could help clinicians consider more tailored treatment approaches. However, the study does not establish that body-clock disruption causes depression or that every person identified with this subtype will respond better to circadian-focused treatments. Patients should consult their clinicians before making any changes to prescribed medication, the experts said.

In India, breast cancer is the most diagnosed cancer among women and the leading cause of cancer-related deaths in women. According to the International Agency for Research on Cancer’s GLOBOCAN 2024 estimates, the country recorded approximately 237,231 new cases and 96,100 deaths. Across both sexes, it is the second leading cause of cancer death.

The median age of diagnosis among Indian women is 51, nearly a decade younger than in most developed countries. One hospital-based study estimates that 25% of cases occur in women under 40, underscoring the importance of breast awareness, timely symptom evaluation, clinical examination and individual risk assessment. The Breast Imaging Society of India recommends mammography screening from age 40, considering individual risk and available resources.

Breast cancer risk does not suddenly begin at a particular birthday, and two women of the same age may have very different risk profiles. Women should be encouraged to become familiar with the usual appearance and feel of their breasts and to seek prompt clinical evaluation for unexplained breast changes. In India, where breast cancer often presents at a comparatively younger age and access to high-quality imaging is uneven, discussions about early detection should extend beyond age alone. Family history, inherited susceptibility, previous breast findings and other recognized risk factors can help determine whether a woman may benefit from earlier assessment, specialist referral or additional imaging.

Why individual risk matters

A risk-informed approach should consider several factors:

• Family history: Breast or ovarian cancer in close relatives, particularly diagnoses at younger ages, cancer affecting both breasts, male breast cancer, or multiple affected relatives may indicate inherited susceptibility. This may warrant earlier risk assessment before age 40.

• Genetic factors: Women with BRCA1 or BRCA2 gene variants may also require earlier than average-risk screening, starting as early as age 25.

• Breast density: Dense breast tissue can lower the sensitivity of mammography and is independently associated with breast cancer risk. Supplemental imaging such as MRI may be considered in selected women, based on the overall risk, the quality of available imaging and the potential for false-positive results and unnecessary biopsies.

• Previous breast findings: A previous high-risk breast lesion, atypical biopsy result or suspicious imaging finding may change the recommended screening frequency or method. Women with such findings should follow an individualized plan developed with their physician.

Persistent inequalities in access

Access to breast assessment, imaging and specialist interpretation remains highly unequal across India. The lifetime prevalence of breast cancer examination is only 8.8 per 1,000 women, with uptake varying by education, economic status and geography. High uptake among educated, affluent, and urban women, especially in southern India, highlights how social determinants and health system barriers shape access to breast cancer screening. India also faces shortages and maldistribution of imaging specialists, with approximately one radiologist per 100,000 people, compared with one per 10,000 in the US. Specialists are disproportionately concentrated in urban areas.

Addressing these inequalities requires more than awareness campaigns. Priorities include strengthening clinical breast examination and referral pathways, training frontline health workers, expanding access to diagnostic imaging and pathology, ensuring timely follow-up after abnormal findings, and monitoring outcomes across socioeconomic and geographic groups.

Where artificial intelligence could support early detection

Artificial intelligence (AI) is being evaluated as a potential support for breast cancer detection in settings where imaging capacity and specialist availability are limited. Depending on the technology and clinical context, AI may assist with triage, image interpretation, workflow prioritization or risk estimation. Its clinical value depends on appropriate validation, reliable referral pathways, diagnostic confirmation, quality assurance and ongoing monitoring for unequal performance across population groups.

Integrating community health workers, portable AI technology and digital referral pathways within primary health care could potentially help reach women who face geographic, financial or health-system barriers. The most important feature is not the algorithm alone, but the complete pathway linking awareness, initial assessment, referral, diagnostic confirmation and treatment. AI output is not a diagnosis. It must be interpreted alongside the patient’s clinical history, risk factors, examination findings and appropriate diagnostic imaging.

Translating personal risk into informed screening decisions

For women, a more personalized approach does not mean performing more tests in every case. It means identifying those who may benefit from earlier, more frequent or different forms of assessment while avoiding unnecessary imaging and procedures among women unlikely to benefit.

As part of a shared decision-making conversation, women may wish to ask their physician:

• Based on my age and personal risk factors, when should breast cancer screening begin?
• Does my family history suggest that I need a formal risk assessment?
• Would referral for genetic counselling be appropriate for me?
• If I have dense breasts, how does that affect the interpretation of my mammogram and my overall risk?
• Do previous breast symptoms, imaging findings or biopsy results change my follow-up plan?
• Which screening or diagnostic services are available locally, and what follow-up will be provided if an abnormality is found?
• Would a formal breast cancer risk-assessment help guide my screening plan?

Breast Cancer Awareness Month is an opportunity to advocate for equitable care pathways, from risk assessment and early detection to diagnosis and timely treatment. In India, a key challenge is ensuring every woman with a concerning symptom or abnormal finding receives appropriate assessment, diagnostic confirmation and treatment without avoidable delays.
