Sleep changes as we age. When we were kids, we needed 10 to 12 hours of sleep, for teens it is eight to 10 and it decreases to seven to nine as we reach adulthood. But there is always a lack of urgency when it comes to sleep and young adults, many of whom prefer staying up and doing different activities. According to the Centre of Disease Control and Prevention, many national surveys show that about 37% of men, and 39% of people from the age of 45 to 64 reported not getting enough sleep.

Many people in America don't sleep the right amount. This means they either sleep too long or not long enough. But what happens to your body when you do not sleep enough? You just feel tired right? No, when you don't get this much sleep, your body can get stressed. This can make you more likely to get sick. A study published by the JAMA Network Open Sleep Trajectories and All-Cause Mortality Among Low-Income Adults showed that people who don't sleep the right amount have a higher chance of dying early. It's like your body needs that time to rest and fix itself. Without enough good sleep, things can start to go wrong. So, getting the right amount of sleep is super important for staying healthy.

How Was The Study Done?

Scientists wanted to see how sleep habits affect people's health over many years. They looked at almost 47,000 people who were between 40 and 79 years old. They asked them about their sleep habits when the study started, and then again, a few years later. The scientists wanted to see if people's sleep habits changed. They divided people into groups based on if they started with too much or too little sleep, and if their sleep changed over time. For example, some people started sleeping a lot but then started sleeping very little. This helped the scientists see how different sleep patterns affected people's health. They wanted to see the long-term effects of sleep.

The study found that people who had sleep habits that changed a lot had a higher risk of dying early. This means if you started sleeping too much and then switched to sleeping too little, or the other way around, you were more likely to die sooner. They also found that these people had a higher risk of heart problems. The risks were even higher for some groups of people, like white adults and people with higher incomes.

Sleep Deprivation And Its Effect On The Body

If you often doze off when you are sitting and reading, watching a movie, talking to someone, sitting quietly after lunch or even during a few minutes of traffic, you may be sleep deprived according to the National Heart, Lung, and Blood Institute. They explain how sleep deprivation can cause issues with learning, focusing and reacting to certain things. The symptoms of sleep deprivation in kids differ a little as they might be overly active and have trouble paying attention to certain things. If you are experiencing sleep issues, make sure to speak to a healthcare professional who will help you identify the issues and direct you towards the treatment or changes you must make. Here are some ways sleep helps your body.

Repairs Your Heart

Good sleep allows your heart and blood vessels to heal. This keeps them strong and healthy, reducing the risk of heart problems.

Controls Hunger

Sleep helps balance your hunger hormones, so you don't feel too hungry. This helps prevent eating too much and keeps your weight healthy.

Manages Blood Sugar

Proper sleep helps your body use insulin correctly. This lowers the chance of high blood sugar, which can lead to diabetes.

Supports Growth

Deep sleep releases growth hormones, helping kids and teens grow. It also repairs body tissues, which is important for everyone.

Boosts Immunity

When you sleep well, your body's defense system gets stronger. This helps you fight off germs and stay healthy.

Following the water contamination emergency in Indore, similar concerns have now surfaced in Madhya Pradesh’s capital. Groundwater samples collected from four locations in Bhopal have tested positive for E. coli bacteria. In response, the Bhopal Municipal Corporation has barred residents from using groundwater for any purpose.

Officials clarified that the contamination is restricted to underground water sources and has not spread to the treated piped water supplied across the city. According to ANI, civic teams have tested 1,810 water samples so far and inspections are still underway in all zones.

E. coli was the same bacteria responsible for Indore’s recent water crisis, which claimed 20 lives, including that of a five-month-old infant. As per a report by Dainik Bhaskar, fear has gripped several neighbourhoods in Bhopal, with residents hesitant even to touch the water. Locals say the water is unfit not only for drinking but also for washing hands, utensils, or bathing. In some areas, tap water reportedly turns reddish within minutes and emits a strong, foul smell. Adding to the concern, iron levels in the water are said to be nearly 100 times above permissible limits.

Here is what you need to know about E. coli, how it spreads, its symptoms, and ways to stay safe.

What Is E. Coli Bacteria?

Escherichia coli, commonly known as E. coli, refers to a group of bacteria that naturally live in the intestines of humans and animals. Most of these strains are harmless and even play a role in digestion. However, certain types can trigger illness when they enter parts of the body where they do not belong or release harmful toxins.

These disease-causing strains attach themselves to body cells and produce toxins, leading to infection and inflammation.

What Happens During An E. coli Infection?

An E. coli infection occurs when harmful strains of the bacteria enter the body. It most often affects the digestive system, causing symptoms such as watery diarrhoea, abdominal pain, and gastroenteritis. In some cases, the bacteria can also infect the urinary tract.

Certain strains produce Shiga toxin, which can lead to severe complications, including kidney damage, especially in children and older adults.

Why E. coli Infections Occur?

E. coli has many strains. While some support gut health, others can cause serious illness. Experts classify the harmful types based on how they attach to cells and the toxins they release. Several strains are known to cause diarrhoeal diseases, including:

• Shiga toxin-producing E. coli (STEC)
• Enterotoxigenic E. coli (ETEC)
• Enteropathogenic E. coli (EPEC)
• Enteroaggregative E. coli (EAEC)
• Enteroinvasive E. coli (EIEC)
• Diffusely adherent E. coli (DAEC)

Other important strains include uropathogenic E. coli, which is a common cause of urinary tract infections, and E. coli K1, which can lead to meningitis in newborns, according to the Cleveland Clinic.

Common Signs Of E. coli Infection

An infection affecting the gut often begins with digestive symptoms. These may include:

• Diarrhoea that is watery and sometimes blood-stained
• Abdominal pain and cramping
• Reduced appetite
• Mild fever

The Cleveland Clinic notes that watery diarrhoea is usually the earliest symptom when the gastrointestinal tract is involved. Symptoms can vary depending on which part of the body is infected.

How To Protect Yourself From E. Coli?

Preventing E. coli infection largely depends on basic hygiene and safe food practices. Since the bacteria spreads through contaminated food, water, and faecal matter, simple precautions can lower the risk significantly.

Maintain hand hygiene

Wash hands thoroughly with soap and water for at least 20 seconds before eating or cooking, after using the toilet, changing diapers, or handling animals. Proper handwashing removes bacteria and limits its spread.

Practice safe food handling

Use separate cutting boards and utensils for raw meat and ready-to-eat foods. Clean kitchen surfaces and tools with hot, soapy water after each use. Keep raw meat away from fruits and vegetables to avoid cross-contamination.

Cook food completely

Ground meat should be cooked to at least 160°F or 71°C, while poultry needs to reach 165°F or 74°C. Using a food thermometer ensures food is properly cooked and free from harmful bacteria.

Clean fruits and vegetables

Wash all produce under running water just before consumption, even if you plan to peel it. This helps remove bacteria picked up from soil or contaminated irrigation water.

Choose safe drinks

Consume only pasteurised milk and juices, and rely on boiled or treated municipal water. Avoid unpasteurised products and untreated water, as pasteurisation effectively eliminates dangerous E. coli strains.

We often hear of dementia as an adult, or older people's disease, but, a father from Glasgow shares how his four-year-old daughter was diagnosed with the condition. Childhood Dementia news of Darren Scott's daughter was delivered to him like a "complete thunderbolt", he tells Sky News. She was diagnosed with the condition before she turned four. Five doctors were waiting, when Sophia Scott, who had just turned four, were summoned to a Glasgow hospital room. Then came the worst news. Scott was told that his daughter could not live beyond the age of 16. "We were told... there was nothing they could do. It was a moment that broke us, shattered our lives. We have never recovered," he says.

What Is Childhood Dementia?

As per Dementia Australia, childhood dementia is a rare brain condition that affects one in every 2,900 babies globally. Childhood dementia is a group of serious brain conditions that interfere with a child’s memory, behavior, emotions and ability to communicate. It isn’t caused by lifestyle or ageing. Instead, it stems from more than 100 rare genetic disorders that children are born with. These include conditions such as Niemann-Pick type C, Batten disease and Sanfilippo syndrome.

No two children experience childhood dementia in the same way. The illness progresses differently for each child, but one thing remains constant: there is currently no cure. Like adult dementia, childhood dementia is progressive, meaning symptoms worsen over time. Heartbreakingly, around half of all affected children do not survive beyond the age of 10.

What causes childhood dementia?

Childhood dementia is genetic. Globally, about one in every 2,900 babies is born with a condition that can lead to childhood dementia. In Australia alone, an estimated 1,394 children were living with dementia in 2021.

The conditions that cause childhood dementia fall into several categories, including inborn errors of metabolism, lysosomal disorders, mitochondrial disorders, mucopolysaccharidoses, leukodystrophy, neurodegeneration with brain iron accumulation (NBIA), and peroxisomal diseases.

Signs and symptoms to look out for

Symptoms can begin in early childhood or appear much later, sometimes not showing up until the teenage years. The progression may be rapid or unfold slowly over several years, deeply affecting both the child and their family.

Much like adults with dementia, children may struggle with memory loss, confusion, changes in personality, anxiety or fear, and severe sleep disturbances. They may also find it difficult to concentrate, learn, communicate or understand things, and some experience behavioral challenges such as hyperactivity.

In addition, childhood dementia can affect the body beyond the brain. Children may develop problems with their bones or joints, experience issues with the heart, lungs or digestive system, lose their ability to move, see or hear, or have seizures.

As the condition advances, children gradually lose skills they once had — talking, walking, reading, writing and playing. Eventually, the body itself begins to shut down. Without major medical breakthroughs and more research, most children with childhood dementia will continue to face a shortened life, often not surviving beyond their teenage years.

India is staring at a sharp rise in lung cancer cases over the next few years, with experts warning that the disease is no longer confined to smokers alone. A recent study published in the Indian Journal of Medical Research projects a significant increase in lung cancer incidence by 2030, with certain regions, particularly the North-East, expected to bear a disproportionate burden. Alarmingly, women are showing one of the fastest rises in new cases.

At a time when the country is on the brink of what researchers describe as a “tsunami” of lung cancer cases, doctors stress that public awareness, early detection, and breaking long-held myths are more important than ever.

Lung Cancer Is No Longer Just a Smoker’s Disease

Lung cancer has long been associated almost exclusively with smoking, but experts say that narrative is outdated. Speaking to The Times of India (TOI), Dr Arun Kumar Goel, Chairman – Surgical Oncology at Andromeda Cancer Hospital, Sonipat, explained that while smoking remains the biggest risk factor, non-smokers are increasingly being diagnosed with the disease.

“Air pollution, indoor cooking smoke, passive smoking, radon gas exposure, occupational hazards like asbestos, and even family history can contribute to lung cancer,” Dr Goel explined. He added that adenocarcinoma, a subtype of lung cancer, is particularly common among non-smokers and appears to be linked more to environmental and genetic factors than tobacco use.

Early Symptoms Are Easy to Miss

One of the biggest challenges with lung cancer is that its early symptoms are often vague and easily mistaken for common respiratory problems. Dr Goel told TOI that persistent cough, changes in cough pattern, coughing up blood or mucus, unexplained chest pain, breathlessness, fatigue, and sudden weight loss are warning signs that should not be ignored.

“In India, lung cancer symptoms often overlap with illnesses like tuberculosis, which leads to delays in diagnosis,” he said. As a result, many patients only seek medical help when the disease has already progressed to an advanced stage.

What a Diagnosis Changes Overnight

A lung cancer diagnosis can be life-altering, both physically and emotionally. According to Dr Goel, patients are suddenly faced with difficult treatment decisions, ranging from surgery and chemotherapy to radiation or targeted therapy. Physical symptoms such as breathlessness and exhaustion can significantly affect daily life.

Emotionally, patients may experience shock, anxiety, fear about the future, concerns for their families, and a loss of independence. “Support from medical teams, counselling services, and loved ones plays a crucial role during this period,” he said.

The Biggest Myth That Delays Care

The most damaging myth, experts say, is the belief that lung cancer only affects smokers. Dr Goel warned that this misconception often results in non-smokers dismissing symptoms or doctors delaying screening. “Anyone can develop lung cancer, regardless of smoking history,” he said.

Early Detection Can Save Lives

If there is one message the public should remember, Dr Goel said, it is that early detection can dramatically improve outcomes. Persistent cough lasting several weeks, unexplained breathing difficulties, or ongoing chest discomfort should prompt immediate medical attention.

“Recognizing symptoms early and seeking help can change the course of treatment and significantly improve quality of life,” he said.
