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!

Sleep disturbances are among the most debilitating symptoms of Alzheimer’s disease. It often appears years before significant memory decline and other symptoms.

A new study from researchers at the University of Kentucky suggests that this sleep loss may not be permanent.

Instead, it could be driven by an immune response in the brain that may be reversible, sparking hope for new treatments.

Published in the journal Alzheimer’s & Dementia, the study found that brain immune cells called microglia, rather than amyloid plaques themselves, are the primary cause of sleep disruption in Alzheimer’s disease.

In mouse-based trials, researchers were able to restore more than two hours of sleep per day by temporarily removing these immune cells, without reducing amyloid plaques.

Can Sleep Be Restored In Alzheimer’s Patients?

For years, scientists believed that sleep problems in Alzheimer’s were caused by the accumulation of amyloid plaques or the gradual death of brain cells. However, this study points in a different direction.

Researchers discovered that when amyloid plaques begin forming in the brain, they activate microglia, the brain’s resident immune cells.

Instead of protecting the brain, these cells cause inflammation that keeps brain circuits active, preventing sleep.

Using a drug called pexidartinib (PLX3397), the researchers temporarily depleted around 87% of microglia in Alzheimer’s mouse models.

This restored over two hours of daily sleep, particularly non-rapid eye movement (NREM) sleep, which is essential for tissue repair, memory strengthening, and clearing waste products from the brain.

Notably, the improvement occurred without changing amyloid plaque levels, suggesting that inflammation is manageable.

'Paradigm Shifting' Findings

Lead researcher Dr. Shannon L. Macauley, associate professor of physiology at the University of Kentucky College of Medicine, said, “Basically, we showed that it is not the plaques themselves, or solely dysfunctional neurons, that cause sleep loss but actually microglia.

Microglia are immune cells that, when they respond to plaques, kick off this elaborate cascade of inflammation, as if the microglia are partying all night, and keeping the brain awake.”

She also highlighted why losing restorative sleep can accelerate disease progression.

“That restorative sleep is super important for physical repair, learning and memory and washing out the toxins of the day. When Alzheimer’s patients lose this stage, they lose their brain’s primary cleaning cycle, creating a feed-forward loop that may drive further damage,” she explained.

First author Dr. Nicholas J. Constantino said one of the biggest surprises was that sleep problems did not worsen as amyloid plaques increased.

“I expected that as plaque burden became more severe, sleep disruption would also worsen. The disruptions in sleep… did not worsen by 18 months, despite more than double the amount of plaque burden,” Constantino said.

Why Do Alzheimer’s Patients Lose Sleep?

Poor sleep and Alzheimer’s create a vicious cycle. Sleep deprivation reduces the brain’s ability to clear amyloid-beta and tau proteins, which can accelerate disease progression, while worsening sleep.

Sleep disturbances affect up to half of people living with Alzheimer’s disease. The disease disrupts sleep due to various reasons:

Overactive microglia: As shown in the new study, immune cells become chronically activated by amyloid plaques, releasing inflammatory signals that keep the brain in a heightened state of activity.

Damage to sleep-regulating brain regions: Alzheimer’s progressively affects areas like the hypothalamus and brainstem that regulate the sleep-wake cycle.

Loss of NREM sleep: Due to lack of deep sleep, the brain’s ability to clear metabolic waste, including amyloid plagues weakens.

Circadian rhythm disruption: Degeneration of the brain’s internal clock leads to broken sleep and daytime drowsiness. This fuels confusion and agitation associated with the disease.

Obesity has always been considered as one of the contributors to heart disease, diabetes, and stroke.

Now, growing research suggests that excess body fat, particularly in your 40s and 50s, may also accelerate brain aging and raise the risk of long-term cognitive decline.

Researchers say that obesity is not just linked with memory problems but also to significant changes in the brain structure.

Maintaining a healthy weight, especially during midlife, could help prevent memory problems and overall cognitive decline.

Higher BMI Linked To Faster Brain Aging

A recent study by researchers at the University of Georgia followed more than 8,200 adults aged 50 years and older for nearly 24 years.

The researchers found that individuals whose body mass index (BMI) increased over time experienced faster declines in cognitive performance than it would with normal aging. Excess body weight affected several aspects of cognition, including memory, planning, decision-making, problem-solving, emotional regulation, and concentration.

Lead author Dr. Claire Sexton (University of Georgia College of Public Health) said, "Maintaining a healthy body weight throughout adulthood may be an important strategy for preserving cognitive health later in life."

The study adds to the evidence that preventing weight gain throughout adulthood could become crucial for reducing dementia risk.

How Does Obesity Affect The Brain?

Chronic Inflammation

Obesity causes chronic low-grade inflammation, which can potentially damaging neurons essential for learning and memory.

Insulin Resistance

The brain relies on glucose for energy. Insulin resistance, common in obesity, may impair how brain cells use glucose, affecting memory and thinking.

Reduced Blood Flow

Obesity increases the risk of hypertension, atherosclerosis and vascular disease, reducing blood supply to brain tissue and potentially accelerating cognitive decline.

Visceral Fat

Experts believe visceral fat, the fat surrounding internal organs, may be more damaging than body weight alone. It produces inflammatory chemicals linked to brain changes and dementia risk.

Growing Evidence

The latest findings are supported by several years of research. A large review published in Practical Neurology concluded that obesity is associated with smaller hippocampal volume, temporal lobe atrophy, mild cognitive impairment and increased Alzheimer's disease risk.

Some studies have suggested that obesity during midlife may nearly double the risk of developing Alzheimer's disease or dementia later in life.

Another review on obesity and aging reported that higher BMI is associated with poorer verbal memory, slower information processing and reduced executive function, particularly among older adults.

In January 2026, researchers also used genetic analyses to suggest that obesity and high blood pressure may directly contribute to dementia.

Can The Risk Be Reduced?

With a few lifestyle improvements, overweight and obese individuals can maintain a healthy BMI, reducing the risk of faster brain ageing and cognitive degradation. Experts recommend focusing on overall metabolic health rather than the number on the weighing scale alone.

Maintaining a healthy weight, regular exercise, controlling blood pressure, cholesterol and diabetes, following a Mediterranean diet, getting adequate sleep, remaining socially and mentally active can help maintain a healthy body weight.

Living with someone who has hepatitis can be worrying. People tend to immediately wonder whether they are at risk simply by sharing meals, hugging, or living under the same roof.

Fortunately, the answer depends on the type of hepatitis, and in most cases, everyday household contact does not spread the virus.

Dr. Shalimar, Prof. Department of Gastroenterology, AIIMS explains, "Hepatitis means inflammation of the liver. There can be many causes, but viral hepatitis is one of the most common. There are different hepatitis viruses, including A, B, C, D, and E. Some cause acute illness, while others can lead to long-term liver damage, including cirrhosis and liver cancer."

Experts say misinformation surrounding hepatitis often leads to unnecessary fear and stigma, causing patients to feel isolated. Understanding how different hepatitis viruses spread can help families protect themselves without avoiding normal interactions.

Can You Get Hepatitis By Living With Someone?

Dr Nanda Kishore M, Gastroenterology, Athulya Geriatric Care Hospital, answers our question, "No, Hepatitis is not a communicable disease that spreads through everyday contact such as hugging, holding hands, coughing, or sneezing."

For most forms of hepatitis, the answer is no. However, hepatitis B is spread through contact with infected blood and certain body fluids. Household transmission is possible, but it generally occurs when infected blood enters another person's bloodstream.

Possible household risks include sharing:

• Razors
• Toothbrushes
• Nail clippers
• Glucose monitoring devices
• Any item contaminated with blood

Dr. Kishore says that the mode of transmission largely depends on the type of hepatitis infected.

He says, "Hepatitis A and E are predominantly spread via means of contaminated food and water, while Hepatitis B and C are transmitted through infected blood and certain bodily fluids."

Hepatitis B is preventable by vaccine. Household members of someone with chronic hepatitis B are usually advised to get tested and vaccinated if they are not already immune.

Dr. Shalimar says, "For hepatitis B, current treatment controls the infection, and newer therapies under development offer hope for a functional cure in the future. Vaccination has dramatically reduced hepatitis B in many parts of the world. Expanding vaccination coverage remains one of the most effective ways to prevent the disease."

Living with a hepatitis infected individual is generally safe given that basic hygiene and recommended precautions are followed strictly. Understanding these facts helps reduce unnecessary fear and stigma associated with it.

Importance of Screening & Prevention

Living with someone who has hepatitis does not mean you need to keep your distance. Instead, focus on practical precautions:

• Never share personal items that may come into contact with blood.
• Cover cuts and wounds.
• Wear disposable gloves while cleaning blood spills.
• Practice good hand hygiene.
• Ensure hepatitis B vaccination if recommended.
• Attend regular medical follow-ups if advised by your healthcare provider.

Dr. Ankur Jain, Associate Director & Unit Head, Gastroenterology, Hepatology & Endoscopy, Max Hospital, Dwarka, explains, "Hepatitis B and Hepatitis C continue to affect millions of people worldwide and remain major causes of liver cirrhosis and liver cancer. Individuals with a history of blood transfusions before routine screening, unsafe injections, or other risk factors should discuss screening with their physician.

He adds, "The liver has an extraordinary capacity to heal, but only if we identify problems early and address the underlying causes. Prevention, timely screening, and simple lifestyle modifications remain our most powerful tools in reducing the growing burden of liver disease in India."
