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.

The IVF laboratory is a critical place where science and precision come together to help create embryos. Here, the expert explains the careful measures that take place inside the lab and the important role of the embryologist in helping couples achieve parenthood.

Many couples are battling infertility and are advised to undergo in vitro fertilization (IVF) to conceive. The couples tend to focus on various factors such as doctor consultations, hormone injections, and embryo transfer.

However, one of the most important parts of the treatment happens in the IVF laboratory. Couples are often unaware of what happens behind the closed doors in the IVF lab.

The IVF Lab: A Highly Controlled Environment

Did you know? Highly trained embryologists work with advanced technology when it comes to handling the eggs, sperm, and embryos in the IVF laboratory.

They are the ones who are responsible for planning and carrying out every step with accuracy to be able to give embryos the best possible environment for healthy development.

The lab is a controlled and sterile space wherein the temperature, humidity, air quality, and lighting are strictly monitored to be able to protect the delicate eggs and embryos.

Even small changes in the environment tend to impact embryo development, so strict quality standards are followed every day by the expert.

From Egg Retrieval to Fertilisation

The process commences after the woman's eggs are collected during a minor procedure. On the same day, the male partner will also provide a semen sample, or previously frozen sperm, if needed. The embryologist will examine both the eggs and sperm under a microscope to check the quality.

Then the healthiest sperm are selected to fertilise the eggs.

Fertilisation will occur after the egg and the sperm are placed together in a special culture dish or via a procedure known as Intracytoplasmic Sperm Injection (ICSI), wherein a single healthy sperm is directly injected into the egg.

The expert will decide the method after knowing the couple's fertility condition.

Monitoring Embryo Development

When fertilisation happens, the embryos are placed in special incubators that closely mimic the conditions inside the human body.

Over the next few days, embryologists monitor their growth and development, and some embryos may undergo genetic testing to identify certain inherited or chromosomal conditions before they are transferred.

The Embryologist's Role in Ensuring Safety and Success

Understand that the embryologist maintains detailed records and follows strict identification protocols to ensure every egg, sperm, and embryo is accurately matched with the correct patient.

Hence, the embryologist plays a vital role in every successful IVF journey.

Ravi is 34 years old. He goes to the gym three times a week, weighs a healthy 68 kg, and has never been diagnosed with diabetes or high blood pressure. During his company's annual health check-up, an ultrasound revealed four unexpected words: Grade 1 Fatty Liver.

Like many people, Ravi was shocked. "How is that possible?" he asked. "I'm not overweight."

The answer reflects a growing reality that is changing how liver specialists understand one of India's fastest-growing liver diseases.

The Old Story Vs The New Reality

For years, fatty liver—now medically known as Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD)—was considered a condition affecting people who were overweight, had diabetes, or consumed excessive alcohol.

That understanding is no longer complete.

Today, we increasingly diagnose fatty liver in individuals who are lean, appear metabolically healthy, and do not consume alcohol. This condition, often referred to as lean MASLD, accounts for nearly 10–20% of fatty liver cases in Asia. Given the unique genetic and metabolic profile of South Asians, the true burden in India may be even higher.

So, What Is Actually Going On? The reasons are more complex than body weight alone—and many are hiding in plain sight.

Your Genes May Be Working Against You

Certain genetic variants, particularly PNPLA3, make the liver more likely to store fat even when the rest of the body appears healthy. This genetic predisposition is significantly more common among South Asians than Western populations.

In other words, you may be lean, eat reasonably well, and still develop fatty liver because of your inherited biology.

Hidden Metabolic Dysfunction

A normal body weight does not always mean a healthy metabolism.

Many lean Indians carry excess visceral fat—fat stored around internal organs rather than under the skin. This "skinny fat" phenomenon is especially common in our population and is strongly linked to liver fat accumulation and inflammation, despite a normal BMI.

It's Not Just How Much You Eat — It's What You Eat

A diet rich in refined carbohydrates and added sugars can overwhelm the liver.

Frequent consumption of foods such as white rice, refined flour (maida), packaged snacks, biscuits, sugary beverages, and fruit juices provides excess fructose, which the liver converts directly into fat.

Over time, this process promotes fatty liver—even in individuals who never become overweight.

For most people, dengue is associated with high fever, severe body aches, headache, fatigue, and a temporary drop in platelet count. With proper care, the majority of patients recover completely within a couple of weeks. However, doctors caution that in rare instances, dengue can leave behind an unexpected complication that affects the nervous system rather than the blood—Guillain-Barre syndrome (GBS).

What Is Guillain-Barre Syndrome (GBS)?

GBS is an uncommon autoimmune disorder in which the body's immune system mistakenly attacks the peripheral nerves. It usually develops after an infection, and growing evidence suggests that dengue can be one of the infections capable of triggering this immune response. While the chances remain low, the condition can progress rapidly and requires prompt medical attention.

The condition affects the nerves and can cause increasing weakness in the legs, arms, face and swallowing.

How Dengue Can Trigger GBS

Unlike the fever and body pain seen during active dengue infection, GBS often appears days or even weeks after the patient seems to be recovering. This delay can make it easy to overlook the connection.

Our immune system protects our body by fighting infections. In some rare cases an infection like dengue can trigger a strange immune response where our body mistakenly attacks its own nerves.

Nerves carry signals between our brain and the rest of our body allowing us to move and feel normally. When nerves get damaged it disrupts the signals from our brain leading to muscle weakness tingling and other symptoms.

Someone who has recently recovered from dengue may suddenly notice tingling in the feet or hands, weakness in the legs, difficulty climbing stairs, or an unsteady walk. As the condition progresses, the weakness may spread upwards, affecting the arms, facial muscles, swallowing, or even the muscles responsible for breathing.

The exact reason this happens is believed to be an abnormal immune response. Instead of switching off after fighting the dengue virus, the immune system mistakenly attacks the protective covering of the nerves, disrupting the signals between the brain and muscles. This results in the characteristic muscle weakness seen in GBS.

Guillain-Barre syndrome usually develops when we are recovering from dengue or even days to weeks after the fever has gone away.

Warning Signs You Should Not Ignore

Feeling tired and fatigued is common, after dengue. Usually gets better slowly. However, we need to differentiate it from weakness. Neurological weakness means our muscle movements are affected.

It often starts in our legs. We may notice it is getting harder to climb stairs get up from a chair or walk normally. This weakness can sometimes spread to our arms and face. In cases it can even affect our swallowing or breathing which may require ICU and ventilator support.

Although dengue-related GBS is rare, recognising the warning signs early can make a significant difference. Timely diagnosis and treatment can help reduce complications and improve recovery.

Any person who develops new weakness, numbness, difficulty walking, facial drooping, trouble swallowing, or breathlessness in the weeks following dengue should seek immediate medical evaluation rather than assuming it is part of normal post-viral fatigue.

Why Early Recognition Matters

The reassuring news is that most people with dengue will never develop Guillain-Barre syndrome. Nevertheless, awareness remains important because the condition can become serious if left untreated.

Preventing mosquito bites, eliminating stagnant water around homes, and seeking medical care early for suspected dengue remain the best ways to reduce the risk of both the infection and its uncommon complications.

The main thing to remember this monsoon is simple: feeling tired after dengue's normal but if our weakness is getting worse we should not ignore it. Recognizing this difference. Getting medical help early can help us identify this rare but treatable complication on time.

As dengue cases rise during the monsoon, recovery should not simply be measured by the disappearance of fever. Paying attention to new neurological symptoms after the illness has resolved can help ensure that a rare but potentially life-threatening complication is recognised before it becomes an emergency.
