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.

34 children have been infected in North London due to a measles outbreak. Health officials have confirmed the outbreak from Enfield in laboratory tests. Doctors too have pointed that children were not fully immunized. Measles was earlier eliminated in the UK, however, the disease is making a come back with UK losing its elimination status. The World Health Organization (WHO) also announced the elimination status of UK based on 3,600 suspected cases in 2024.

Unique Symptoms Of Measles

With the disease now making a comeback, the worry is real. Measles has a high transmissibility, and high measles immunity levels are required to prevent sustained measles virus transmission.

This is why herd immunity for measles could be easily breached.

It easily spreads from one infected person to another through breathes, coughs or sneezes and could cause severe disease, complications, and even death.

Symptoms include:

• High fever
• Cough
• Runny Nose
• Rash all over the body

The most unique symptom or the early sign of measles in the Koplik spots. These are tiny white dots that look like grains of salt on red gums inside the cheeks that appear before the red rash starts to appear on a person's face and then the body.

Furthermore, the symptoms of measles are also characterized by the three Cs:

• Cough
• Coryza or runny nose
• Conjunctivitis or red and water eyes

How Long Does The Infection Last?

The progression of the symptom comes in two stages, first is the prodromal stage or Days 1 to 4, where one would notice high fever, cough, runny nose, red and watery eyes, sore throat, fatigue, and Koplik spots.

The second stage is called the rash stage or the days 5 to 10 or even more where rash start to appear on the hairline, and then it runs down the body. It lasts for several days and fades in the same order.

The first symptoms, notes the Centers for Disease Control and Prevention (CDC), appear 7 to 14 days after a measles infection. Often, it could also lead to ear infection, or even diarrhea. Though these complications happen in every 1 in 10 children or individual with measles.

Who Is At Risk Of Measles?

• Children who are younger than 5 years of age: nearly 1 to 3 of every 1,000 children who become infected with measles will die from respiratory and neurologic complication, notes the CDC
• Adults older than 20 years of age
• Pregnant Women
• People with weakened immune system, such as from leukemia or HIV infection

Why Has Measles Return To The UK?

In late 2023, measles outbreaks were reported in the UK, which led to a surge in cases in 2024. Vaccination uptake at the end of 2024 was 92% for the first dose, however, for the second dose, it was below 82%.

Dr Vanessa Saliba, consultant epidemiologist at UKHSA said, "Infections can return quickly when childhood vaccine uptake falls - measles elimination is only possible if all eligible children receive two MMRV doses before school. The NHS is making vaccination easier, including offering the second MMRV dose earlier at a new 18-month appointment to boost uptake and support elimination goals."

She also noted that children and adults must get vaccinated as NHS also offers catch-up jabs.

Dr Baharat Pankhania, from the University of Exeter, as reported by the BBC said, "Measles is an infection that can be prevented by vaccine - and it's extremely concerning that in the UK we now have pockets of low or no vaccine uptake. We urgently need to remedy this situation." Pankhania also noted that there is a need to make the access to GPs easier, and for an effort that could immunize babies in their homes and counter wrong information around vaccine safety.

Often, we underestimate the way our brain works and daydreaming has long been seen as a major sign of creativity. Many artists have used their imagination to bring their work to life. However, science offers a different perspective.

Coined in 2002 Dr. Eliezer Somer, those who experience “maladaptive daydreaming” often fantasize about celebrities, historical figures or idealized versions of themselves. Their imaginations are more elaborate, diverse, and complex as compared to other daydreamers.

A 2012 Consciousness and Cognition study found that maladaptive daydreamers spend, on average, 57 percent of their waking hours daydreaming far more than their counterparts.

Dr Somer explains: "The greatest difference is the maladaptive daydreamers reported that the activity interfered with their daily life. They also reported higher rates of attention-deficit and obsessive compulsive symptoms, and more than 80% used kinesthetic activity or movement when daydreaming, such as rocking, pacing or spinning"

He further noted that while everyone experiences moments of mind-wandering, it usually does not interfere with daily life. But maladaptive daydreaming does interfere in regular life. The condition has not been classified as a mental illness and there is no treatment for it yet.

What Do People Say?

Many Reddit users have shared their experiences with maladaptive daydreaming, often asking questions such as: “Is it normal to daydream for such long hours?”

While some responses described daydreaming as a form of dissociation when bored, others relied on music or movies to fuel fantasies of being a “better version” of themselves, often struggling to return to reality.

Common Symptoms Of Maladaptive Daydreaming

Here are some early signs of maladaptive daydreaming to keep an eye out for:

• Compulsive need to daydream
• Avoiding social interaction and activities
• An inability to perform work or other daily tasks
• Extreme feelings of shame or guilt
• Feeling a compulsive need to daydream that you can't control
• Making a conscious effort to stop or lessen daydreaming episodes.
• Intense and extremely vivid daydreams
• Complex and elaborate daydreams, often with many people involved
• Daydreams accompanied by repetitive movements such as pacing
• Prolonged daydreams that may last hours at a time
• A feeling of disconnect or dissociation from people and reality during the episode.

What Does Science Say?

Rachel Bennett, a member of Dr. Somer’s online community, shared she usually dreams up new episodes of her favorite Japanese animé characters and TV shows. She’s also created four families of fictional characters which have grown with her over the years.

“I’d much rather stay home and daydream than go out,” she said.

What Causes Maladaptive Daydreaming?

Dr. Somer noted that about one-quarter of maladaptive daydreamers are trauma survivors who use daydreaming as an escape. Many report family members with similar tendencies, as well as being shy or socially isolated.

Meanwhile, a Harvard Medical study found that 80 percent of maladaptive daydreamers have ADHD, followed by anxiety disorders, depression, and OCD. Researchers believe daydreaming often acts as a coping mechanism for pent-up emotions that cannot be expressed in real life, so they are released through imagination instead.

How Do You Cope With Maladaptive Daydreaming?

Experts emphasize that maladaptive daydreaming is not an extreme condition requiring formal diagnosis, but many people have shared strategies that help:

• Exercise: One forum user reported swimming daily, gradually reaching 2,000 meters, which acted as meditation and grounded them in reality.
• Remove triggers: Avoid activities that spark daydreaming episodes.
• Practice mindfulness: Stay present and aware of thoughts.
• Limit music use: Music is a common trigger.
• Scheduled daydreaming: Set aside specific times with a timer, then consciously exit the session.
• Seek professional help: Therapies such as CBT, DBT, and mindfulness-based stress reduction have shown benefits.
• Stay busy: Engage in tasks to prevent wandering thoughts.
• Improve sleep quality.
• Make daydreams less appealing: Reduce instant gratification.
• Self-development and creativity: Channel imagination into productive outlets.
• Journaling: Record thoughts daily or weekly.
• Practice self-acceptance.
• Find group support.

In January 2026, a Guardian investigation uncovered something deeply unsettling. Google’s AI summaries, designed to quickly answer search queries, were giving users inaccurate health information. Some of the advice was not just misleading but potentially dangerous.

One striking example involved liver function tests. The AI presented incorrect “normal ranges,” which could make someone with a serious liver infection believe their reports were fine. Following the investigation, Google quietly removed AI Overviews for certain queries such as “normal range for liver function tests” and similar searches.

Soon after, another finding raised further alarm. Researchers discovered that Google’s AI Overviews frequently relied on YouTube rather than established medical websites when responding to health questions. Considering nearly two billion people use Google search every month, the implications were hard to ignore.

Is AI Replacing Medical Advice

For years, doctors have warned about “Dr Google” and self diagnosis. But the situation has now moved beyond search results. People are increasingly asking AI tools directly for answers to complex medical problems.

The search optimization platform SE Ranking analyzed more than 50,000 health searches in Germany. The most cited source in AI responses was YouTube, which accounted for 4.43 percent of citations. That is about 3.5 times more than netdoktor.de, one of the country’s biggest consumer health portals. It was also cited more than twice as often as the well known medical reference MSD Manuals.

Only 34.45 percent of citations in AI Overviews came from reliable medical sources. Government health institutions and academic journals together contributed roughly one percent. No hospital network, university, or medical association came close to YouTube’s citation numbers.

Why Experts Are Concerned

The concern is simple. YouTube is a video platform, not a medical publisher. While qualified doctors upload educational videos, the platform also hosts wellness influencers, life coaches, and creators without medical training.

In one particularly worrying example, Google’s AI advised pancreatic cancer patients to avoid high fat foods. Medical experts say this recommendation is the opposite of what many patients actually need and could increase mortality risk.

AI Overviews also gave incorrect information about women’s cancer screening tests. Experts warned this could lead people to dismiss serious symptoms and delay diagnosis.

The Rise of Chatbot Medicine

The shift is not limited to search engines. Chatbots are rapidly becoming everyday health advisers. OpenAI estimates about 40 million people globally use ChatGPT for healthcare guidance each day.

A 2026 Health and Media Tracking Survey by the Canadian Medical Association found roughly half of Canadians consult Google AI summaries or ChatGPT for medical concerns.

The outcome has not been reassuring. People who followed AI advice for self diagnosis and treatment were five times more likely to experience negative health effects than those who did not.

Studies help explain why. A 2025 University of Waterloo study found GPT 4 answered open ended medical questions incorrectly about two thirds of the time. Another 2025 Harvard study showed chatbots often agreed with flawed assumptions instead of correcting users, such as confusion between acetaminophen and Tylenol.

Researchers say AI systems tend to be overly agreeable and confident, prioritizing helpful responses rather than critical reasoning.

Confidence Versus Care

Despite knowing AI can be wrong, many people still rely on it. Long waits for specialists, lack of family doctors, and limited access to healthcare make instant answers appealing.

The real concern is not curiosity but unquestioned trust. Looking up symptoms is one thing. Acting on AI advice without verification is another.

The technology is powerful and useful, but when confident sounding answers replace medical judgement, the consequences can affect real lives.
