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.

Blockbuster drug Ozempic, known for treating type 2 diabetes and obesity, has a surprising side effect. A new study published in The Lancet Psychiatry showed that the GLP-1 receptor agonists might prevent worsening of depression and anxiety.

People with diabetes or obesity are generally more likely than the general population to suffer from depression and anxiety. It is because both diabetes and obesity increase the risk of mental ill-health, and vice versa.

The findings showed that people with diabetes using semaglutide had a substantial decrease in hospitalizations and sick leave due to mental illness, including less worsening of depression, anxiety, and self-harm.

“Our findings suggest that GLP-1 drugs, particularly semaglutide, might contribute to better mental health in people with diabetes and obesity, but since this was an observational study, controlled clinical trials are needed to confirm the results,” said Jari Tiihonen, specialist physician and professor at the Centre for Psychiatry Research, Karolinska Institutet.

What Did The Study Find?

The research, led by an international team from Griffith University, the Karolinska Institutet, and the University of Eastern Finland, tracked Swedish national registers between 2009 and 2022.

It included 95,490 people, of which GLP-1 receptor agonists were used by 22,480 individuals during the follow-up period.

Semaglutide was associated with a decreased risk of worsening

• depression
• anxiety
• substance use disorder
• self-harm.

Patients using semaglutide experienced a 42 percent lower risk of hospitalization for mental health issues during periods of use, compared to periods when they were not taking the drug.

More specifically, the risk reduction was 44 per cent for sickness absence or hospital care due to depression, 38 per cent for anxiety disorders, and 47 per cent for substance use.

The team also found some benefits with Liraglutide. The drug was associated with an 18 per cent lower risk of sickness absence and hospital care due to psychiatric reasons.

How Does Semaglutide Work?

Semaglutide works as a GLP-1 receptor agonist that mimics the GLP-1 hormone to regulate appetite and blood sugar. It slows gastric emptying and makes you feel fuller longer. It also signals the brain to reduce hunger and cravings, and triggers the pancreas to release insulin when blood sugar is high.

They work by increasing insulin release in a glucose-dependent manner, decreasing the liver's production of glucagon, and slowing down the emptying of the stomach, which helps lower blood sugar levels after a meal. They also act on the brain to suppress appetite and increase feelings of fullness, leading to reduced calorie intake.

In people with type 2 diabetes, notes Harvard Health, the body's cells are resistant to the effects of insulin and the body does not produce enough insulin, or both. This is when GLP-1 agonists stimulate the pancreas to release insulin and suppress the release of another hormone called glucagon.

These drugs also act in the brain to reduce hunger and act on the stomach to delay emptying, so you feel full for a longer time. These effects can lead to weight loss, which can be an important part of managing diabetes.

In the wake of a young doctor from Chandigarh accusing a well-known private hospital of unnecessarily admitting patients to Intensive Care Units (ICUs), it is imperative to understand who truly requires critical care.

In a widely shared video posted on the social media platform Instagram, Dr Prabhleen Kaur alleged that the hospital is making the patients remain admitted in the ICU for as long as possible to mint money.

The doctor did not mention the name of the hospital. And HealthandMe could not independently verify the details and the authenticity of the post.

However, the incident reignited concerns over accountability, patient safety, and standards of care in the country.

Speaking to HealthandMe, Dr. Sachna Shetty, Consultant Emergency Medicine at Jaslok Hospital and Research Centre, said that: "ICU admissions are for patients with life-threatening conditions needing intensive support".

"This includes shock, respiratory failure, neurological emergencies, cardiac issues, and multi-organ dysfunction," the doctor added.

What Is ICU? Who Needs Critical Care?

The NHS UK explains that intensive care units (ICUs) are specialist hospital wards that provide treatment and monitoring for people who are very ill.

They're staffed with specially trained healthcare professionals and contain sophisticated monitoring equipment.

Also called critical care units (CCUs) or intensive therapy units (ITUs), it is required in cases where a person is seriously ill and requires intensive treatment and close monitoring.

Most people in an ICU have problems with one or more organs. For example, they may be unable to breathe on their own. Some common reasons include:

• a serious accident
• a serious short-term condition
• a serious infection
• a major surgery.

"ICU beds are limited, reserved for those who'll benefit most. Decisions are time-sensitive, based on triage and clinical scoring. It's about who needs advanced life support, not just who looks critical. Fair use of resources is key," the doctor added.

ICU Admissions: What India’s Guidelines Say

India’s ICU admission guidelines—issued by the Ministry of Health and Family Welfare in January 2024 — clearly defines who should and should not be admitted to an ICU. According to the guidelines:

• ICU admissions must be based on the severity of organ failure and the necessity for organ support or in anticipation of a potential deterioration in the patient's medical condition.
• Hospitals cannot admit critically ill patients in ICU in case of refusal by them and their relatives.
• ICU is not recommended in cases where there is no treatment possible or available, and if the continuation of therapy is not going to make an impact on the outcome, especially survival.
• Anyone with a living will or advanced directive against ICU care should not be admitted to ICU.
• Low priority criteria in case of a pandemic or disaster situation, where there is resource limitation, should be taken into account for keeping a patient in the ICU.
• Blood pressure, pulse rate, respiratory rate, breathing pattern, heart rate, oxygen saturation, urine output and neurological status among other parameters should be monitored in a patient awaiting an ICU bed

1. patients with altered level of consciousness,
2. hemodynamic instability,
3. need for respiratory support,
4. patients with acute illness requiring intensive monitoring
5. organ support or any medical condition or disease with anticipation of deterioration.

Guidelines For ICU Discharge Criteria In India

The guidelines stress the importance of physiological parameters returning to near-normal or baseline status.

Furthermore, reasonable resolution and stability of the acute illness that led to ICU admission are essential factors.

Patient and family agreement for ICU discharge, particularly in cases where a treatment-limiting decision or palliative care is opted for, is also highlighted.

Modern lifestyle changes are contributing towards the rising neurological problems among young adults, said health experts today on World Health Day 2026.

World Health Day is observed annually on April 7 to mark the founding day of the World Health Organization (WHO) in 1948 for public health worldwide. World Health Day 2026 will be observed under the theme “Together for health. Stand with science.”

The health experts noted that conditions such as recurrent headaches, mild weakness, strokes, and spine disorders were traditionally more common among older adults. However, modern lifestyle changes—sedentary habits, unhealthy diets, chronic stress, and increased screen time—are now driving a surge of these neurological problems among younger populations.

“The surge in neurological conditions today is not just a clinical challenge, but a reflection of how rapidly our lifestyles are evolving. We are seeing younger patients presenting with serious issues like stroke and spine disorders, conditions that were once more age-associated. This shift makes it imperative to recognize that neurological health is closely linked to everyday habits, stress, and timely medical attention,” Dr. Gaurav Sharma, Senior Consultant - Neurology, Paras Health Panchkula, told HealthandMe.

Neurological Disorders: Silent Onset

The health experts emphasized that the threat of neurological disorders is surging silently. The conditions, ranging from recurrent headaches and mild weakness to strokes and spine disorders, often show no noticeable symptoms in the early stage.

As a result, these go unnoticed until advanced stages, which makes the role of early detection and preventive care more crucial.

“Neurological disorders often progress silently, and by the time symptoms become severe, the condition may already be advanced. One of the biggest challenges we face today is the lack of awareness around subtle early signs, whether it is recurrent headaches, mild weakness, or persistent back issues, which are frequently overlooked or ignored,” Dr. Ritu Jha, Director & HOD - Neurology, Sarvodaya Hospital Sector -8, Faridabad, told HealthandMe.

Health specialists stressed the need to boost early detection, preventive care, and lifestyle modifications to protect brain and nerve health.

They called for changing the mindset from reactive to proactive care. Early identification of symptoms and prompt intervention can dramatically alter outcomes. They recommended:

• timely check-ups,
• awareness of warning signs,
• regular exercise,
• balanced nutrition,
• stress management.

Advancement In Neurological Care

With the progress in precision-driven and minimally invasive neurosurgery, we are now better equipped than ever to treat complex conditions effectively, provided patients seek care at the right time.

“Today’s advanced surgical techniques allow us to operate with greater accuracy while minimizing trauma to the patient, leading to faster recovery and improved long-term outcomes. Bridging the gap between symptom onset and specialist consultation will be key to reducing the overall burden of these conditions,” Dr. Jha said.

Over 7% Indians Engaging In Healthy Aging

A nationwide survey conducted by Local Circles, a Delhi-based community platform and citizen pulse aggregator, for World Health Day 2026, found that more than 7.3 percent of Indians are actively working on slowing aging.

The report showed that preventive healthcare has gained importance, and people are increasingly indulging in healthy practices such as lifestyle, diet, exercise, supplements, and therapy to ensure healthier, more active years.

It noted that fitness trends such as yoga, strength training, and regular physical activity, along with balanced diets rich in antioxidants, are widely promoted to maintain physical health and vitality.

Mental well-being practices, including meditation and stress management, are also being recognized as essential components of healthy aging.
