Every year, World Toilet Day is observed to raise awareness about the global sanitation crisis and encourage action to solve it. The goal set by the United Nation is to achieve safe toilets for all by 2023, as a part of their Sustainable Development Goals.

The UN also states that 3.5 billion people live without proper sanitation and many children also lose their lives due to poor sanitation and unsafe water. This is why World Toilet Day is observed to raise awareness on this issue.

Theme

This year, the theme for World Toilet Day 2024 is "Toilets - A Place for Peace'. This focuses on the growing threat to sanitation that is caused by conflict, climate change, disaster and neglect. When there is a threat to using toilets, it can lead to many health risks.

Not using toilets for too long may lead to Urinary Tract Infection or UTI. For many who do not have access to clean toilets do not drink enough liquid or hold pee for too long. Doctors suggest that holding in pee for too long can cause bacteria to multiply and lead to UTI. By not drinking enough water, your bladder fails to tell the body to pee often, and can cause the bacteria to spread through the urinary tract, which can lead to infection.

Symptoms of UTI:

• Burning or stinging feeling while urinating
• Pain in pelvis or lower abdomen
• Constant urge to empty the bladder
• Strong or foul smelling urine
• Consistently dark urine
• Blood in urine

Holding in pee for too long can also cause your bladder to stretch, making it difficult or even impossible for the bladder to contract and release pee normally. It can also damage your pelvic floor muscles or could lead to kidney stones.

World Toilet Day History And Significance

To prevent such conditions, it is important that everyone has access to clean and safe toilets. In terms of history, the day was established in 2001, by the World Toilet Organization (WTO), which was founded by Jack Sim. However, it was officially recognised by the UN in 2013. The Government of Singapore worked with WTO to create the first UN resolution called Sanitation for All.

India too promotes safe and hygiene toilet through its Swachh Bharat Yojna.

With the onset of winter, Delhi sees a sharp deterioration in air quality, exposing people across age groups to health risks including respiratory problems and eye irritation, among others.

Ahead of the season, the Delhi government has announced 10 interventions targeting major pollution sources, including vehicles, dust, waste and industrial emissions.

“Delhi Clean Air Action 2026 puts 10 focused interventions at the heart of the fight against pollution, targeting key sources from vehicles and dust to waste and industrial emissions. Cleaner air is a shared goal,” Delhi Chief Minister Rekha Gupta said in a post on X.

“We urge every Delhiite to join this effort through active Jan Bhagidari. Every responsible action counts towards a cleaner, healthier Delhi,” she added.

The measures were discussed during a review meeting with the Commission for Air Quality Management (CAQM) and the Delhi Pollution Control Committee (DPCC).

Why Does Delhi’s Air Quality Worsen In Winter?

Delhi-NCR’s air quality deteriorates during the colder months as emissions combine with unfavorable weather conditions.

According to CAQM, falling wind speeds, shallow atmospheric mixing, fog and low temperatures reduce the dispersion of pollutants, allowing particulate matter to accumulate near the ground.

How Does Air Pollution Affect Health?

Air pollution contains tiny particles such as PM2.5 and PM10, along with gases including nitrogen dioxide from vehicle exhaust, sulfur dioxide from industrial emissions and carbon monoxide.

PM2.5 is of particular concern because these extremely small particles can penetrate deep into the lungs and, after entering the bloodstream, trigger inflammation and affect other organs.

The health effects of air pollution go beyond respiratory symptoms such as coughing, wheezing and breathing difficulties. Long-term exposure has been linked to a higher risk of heart disease, stroke, lung cancer, diabetes and chronic respiratory diseases. Exposure during childhood can also affect lung development and respiratory health.

Reducing exposure to polluted air remains important, particularly during periods of poor air quality. A balanced diet and adequate nutrition can also support overall health, although nutrition cannot replace measures to reduce exposure to air pollution.

Red Bull got relief after Delhi High Court overturned a Food Safety and Standards Authority of India (FSSAI) order that instructed the Austrian beverage giant to drop its ‘energy drink’ label. In a recent ruling, the court made its decision after it found that the Indian food regulator did not give sufficient time to the company to present its case.

While the legal fight between the food regulator and the billion-dollar beverage giant boils down to just two words on a can, the health question is much bigger: What does drinking an energy drink like Red Bull actually do to the body?

FSSAI Vs Red Bull

FSSAI had said India does not have a notified food standard specifically defining an “energy drink”, objecting to brands like Red Bull making claims like boosting energy or enhancing focus.

The regulator's concerns also included linked to what these beverages actually contain, particularly excessive caffeine, sugar, and other controversial ingredients like taurine.

The biggest concern that the lawsuit is built upon is what causes the sudden surge of ‘energy’ after someone consumes this drink. Is it giving your body useful energy?

Red Bull’s Ingredients And What It Does To Your Body

Caffeine

One of the main ingredients responsible for the immediate feeling of energy alertness is caffeine. Caffeine stimulates the central nervous system, making you feel more awake and less tired. But that boost does not mean the drink is providing the body with sustained energy in the nutritional sense.

Depending on the product, energy drinks can also contain substantial amounts of added sugar, which adds calories but does not make the drink healthier.

The caffeine content of energy drinks varies considerably. The US FDA notes that energy drinks can contain roughly 41 to 246 mg of caffeine per 12 fluid ounces, depending on the product.

The energy boost claim may comes from the caffeine content, which is what consumers should be mindful about. Too much caffeine can lead to faster heartbeat, palpitations, increased blood pressure, anxiety, jitters, headaches, nausea and sleep disruption. For most healthy adults, the FDA cites 400 mg of caffeine a day.

Energy drinks can also temporarily increase blood pressure and cardiovascular load. A 2024 review and meta-analysis of randomised trials found that energy drinks acutely increased systolic and diastolic blood pressure in healthy adults.

Excess caffeine in young people can cause palpitations, increased heart rate and blood pressure, anxiety, sleep problems and digestive symptoms. Therefore, the FDA and medical experts advise against energy drinks for children and teenagers.

This is also why energy drinks have attracted regulatory restrictions worldwide. England, for example, plans to prohibit their sale to under-16s from April next year.

Sugar

The sugar content is another reason to be careful about how often you drink energy drinks. Regular and frequent consumption of high amounts of added sugar, through liquid calories like energy drinks, can increase overall calorie intake and contribute to weight gain and obesity.

Over time, excess sugar intake is also linked with a higher risk of metabolic problems like type 2 diabetes and fatty liver disease. For people who regularly consume these energy drinks, the concern is therefore not just the caffeine, but also how much added sugar they are consuming with each can.

Taurine

HealthAndMe previously reported that taurine may help fuel the growth of certain leukaemia cells. The research raised questions about taurine's role in blood cancer. The research was about the behaviour of cancer cells and does not establish that taurine-laced energy drinks cause blood cancer in humans.

Taurine occurs naturally in protein-rich foods like meat and fish and is also produced in the human body. Known for its function of maintaining fluid balance, cardiovascular support, and electrolyte regulation, taurine has been touted for years as a "health-enhancing" supplement. Taurine is also added to energy drinks for its claimed brain-boosting and anti-inflammatory effects and is marketed as a means to enhance mental concentration and physical output.

A study by University of Rochester's Wilmot Cancer Institute revealed how leukemia cancer cells hijack taurine as an energy source. Specifically, the cancer cells take in taurine to fuel glycolysis—a biological process that allows them to produce energy and proliferate at a fast rate.

The bottomline is that the Delhi High Court's ruling does not mean that Red Bull has been declared healthy. It addresses whether FSSAI followed the correct procedure when restricting the “energy drink” label. So even though Red Bull can be marketed and sold as an “energy drink”, it cannot be automatically considered healthy.

A new artificial intelligence-based screening tool may be able to analyse just 20 seconds of speech to identify clues linked with type 2 diabetes.

A recent large-scale study found that the AI model could detect type 2 diabetes from short voice recordings, including when its predictions were checked against HbA1c blood-test results.

The researchers say the technology could eventually offer a quick, non-invasive way to triage patients and identify people who may need routine diabetes testing.

The researchers stress upon the fact that this is a just screening tool, not a replacement for conventional blood test for type 2 diabetes.

Can Someone’s Voice Reveal If They Have Type 2 Diabetes?

The very idea of diagnosing a disorder from voice seems strange but researchers have been studying changes in speech as key biomarkers that could give reliable clues about a particular disease.

Type 2 diabetes affect multiple physiological systems, including nerves, muscles and blood vessels. These changes could have a subtle influence on various aspects of speech, like pitch, timing and other acoustic characteristics that are not prominent enough for the human ear.

The AI does not ‘listen’ for someone saying they have diabetes. Instead, it analyses patterns in the voice recording and looks for combinations linked with type 2 diabetes.

What Did The Researchers Find From Voice Recordings?

Researchers developed the model using 63,000 voice recordings from more than 21,000 people in the US and UK and then tested it in a separate group of 7,319 adults. Participants provided short recordings involving reading aloud from Aesop’s fables.

The model showed an area under the curve (AUC) of 0.80 when tested against self-reported type 2 diabetes. It means that the speech tool accurately assigned higher risk scores to individuals who had type 2 diabetes in 80% of the instances.

A secondary analysis of 801 participants also underwent HbA1c testing within three months of voice testing, providing an objective measure of blood sugar control. When the AI tool’s predictions were compared with those results, it achieved an AUC of 0.75 for diabetes and 0.73 for prediabetes.

AI Tool’s Implications In Diabetes Testing

Type 2 diabetes can remain undiagnosed for years, allowing complications to develop before treatment begins. Blood tests like fasting glucose and HbA1c are the conventional ways to diagnose diabetes. One has to go to the clinic, get their blood drawn and wait for some time to get their diabetes diagnosis.

Giedre Cepukaityte, research scientist at thymia, who will be presenting the findings at the European Association for the Study of Diabetes (EASD) in Milan, said, "This is the largest real-world study of speech-based screening for type 2 diabetes to date which also checks the model’s predictions against blood test results as well as against what people reported about their own diagnosis. Those flagged up as higher risk by the model had blood results to match.”

The advantage of voice screening could make a difference in diabetes testing. As someone can do this test without visiting a clinic, this could be the first step people undergo before proper testing. Someone flagged as being at higher risk would need a conventional blood test.

Cepukaityte added, "This has the potential to change what screening looks like. A speech sample can be taken over the phone or through an app, so we can reach far more of the people who need a blood test than current pathways do, particularly those who never get to a health check.”

A voice-based tool could make screening easier for people who do not routinely visit doctors or have difficulty accessing healthcare services. The researchers found that the voice model identified about three-quarters of type 2 diabetes cases, although it also produced false-positive results.

"Our model opens a new route to screening for diabetes. It is not a replacement for a blood test, and it should never stop anyone who thinks they need one from getting one. Our next step is to test the model in clinical settings and to understand how well it works for every group of people, because a screening tool has to work for everyone."

Dr Lucy Chambers, head of research impact and communications at Diabetes UK, said, "More than a million people in the UK are living with undiagnosed type 2 diabetes and are missing out on the support and treatment they need to help them stay well and reduce their risk of developing devastating complications.”

She added, “AI-based technologies could help identify more people who may benefit from diagnostic blood tests, but it’s crucial that they are rigorously designed and tested to make sure no-one slips through the net.Anyone concerned about their risk of type 2 diabetes can use Diabetes UK’s free Know Your Risk tool and should speak to their healthcare team if they have concerns.”
