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 liver is one of the body’s most dependable organs, quietly doing its job in the background every single day. It handles over 500 essential functions—from filtering out toxins and producing key proteins to helping with digestion through bile and keeping your metabolism running smoothly. Most of the time, it does all of this without demanding attention.

For years, liver disease has largely been associated with alcohol. But today, a quieter and increasingly common condition is coming into focus: Non-Alcoholic Fatty Liver Disease (NAFLD), or steatosis. Closely linked to the way we live today, it is affecting a growing number of people, often without any clear warning signs. At the heart of this shift are three closely linked factors: ongoing stress, everyday eating habits that have slowly gone off track, and a noticeable drop in physical activity.

Stress, though often brushed aside, has a real and lasting impact on metabolic health. When the body is constantly in a “fight or flight” mode, cortisol levels stay high. Over time, this often shows up as fat, especially around the abdomen, while also affecting how the body handles insulin. As cells become less responsive, insulin levels rise, and the excess glucose is eventually stored as fat. This fat doesn’t just remain visible; it can quietly accumulate in the liver and begin to interfere with how it works. At the same time, persistent low-grade inflammation creates a setting where the condition can slowly worsen over time.

Diet plays an important role as well. Regularly eating processed foods, refined carbs, and added sugars can quietly tip the body into a calorie surplus, slowly straining its metabolic balance. Fructose—commonly found in sweetened drinks and packaged foods—is largely processed by the liver, putting even more pressure on it over time. When consumed in excess, it pushes the body to convert more sugar into fat, which then starts building up within liver cells over time.

A sedentary lifestyle only adds to this, often without us even realizing it. Because there is little mobility, the body becomes inefficient in using fats and carbohydrates. Over time, weight gain occurs, the body develops insulin resistance, and fatty deposits begin to form in the liver.

Sleep, which is usually ignored, is crucial. If there is insufficient or poor-quality sleep, the body’s circadian rhythm will be disrupted, as well as hormones like ghrelin and leptin, which regulate feelings of hunger and fullness. This increases food consumption and reduces energy expenditure, enabling fat deposition.

The hardest thing about NAFLD is that it is a silent disease. In the first stages of NAFLD, there will be no symptoms felt by the patient. This condition is often diagnosed incidentally when patients undergo physical checkups. Thus, untreated steatosis would eventually turn into NASH, wherein inflammation and injury of liver cells occur. The process then proceeds to fibrosis, cirrhosis, and in severe cases, transplantation of the liver.

The reassuring part is that NAFLD can often be reversed when caught early. In many cases, it comes down to simple, steady choices, eating balanced meals with whole grains, fruits, vegetables, and lean proteins, and staying physically active. Small habits like managing stress through mindfulness or yoga, and getting enough sleep, can make a real difference to metabolic health.

For those at higher risk, including people with obesity, diabetes, or high cholesterol, regular health check-ups become especially important. Spotting the condition early gives you a chance to act before it moves into more serious stages.

The liver, after all, keeps working quietly in the background every single day. Looking after it doesn’t require anything extreme, just consistent, everyday choices that add up over time.

Right now, days' stress no longer comes in bouts; bouts have been turned to a continual rhythm. Deadlines, working overtime, staring at computer screens, lack of sleep, and daily tensions, together with environmental pollution, have resulted in what physicians have started to call the "always stressed" generation. Things like cortisol, the body's primary stress hormone, which is linked to changes in female fertility, albeit subtly, are being blamed more and more nowadays.

Is cortisol making women infertile?

In an interview with Health and Me, Dr. Rubina Pandit, Fertility Specialist, Nova IVF Fertility, Basaveshwaranagar, spoke about the impact of cortisol on fertility in women.

Cortisol is a great help when the body is responding to stress. Among other functions, it regulates energy, metabolism, and immunity. The trouble begins with stress that is sustained for a long time and cortisol levels that remain high continuously. Then it starts to cause disruptions to reproductive health.

The latest studies conducted in 2025 and 2026 indicate that stress over a long period may affect the hormonal balance required for ovulation. A high level of cortisol also changes the brain signals that are responsible for the regulation of the ovaries and that can cause irregular periods or even absence of ovulation. In other words, chances for natural conception will be diminished if ovulation doesn't occur regularly.

More intriguingly, recent research has discovered some new findings about the impacts of stress on infertility. According to a 2026 study, cortisol hormone levels could modify the uterine environment and influence the genes that facilitate embryo attachment and development. In this case, the effect of stress could not only affect ovulation but also interfere with the successful growth of fertilised embryos.

Infertility and chronic stress: The link explained

Another area of study that researchers have focused on is the possible connection between infertility and chronic stress. Recent scientific studies suggest that women under constant stress have markers that signal reduced ovarian functioning. Moreover, prolonged stress is known to negatively affect sleep, libido, and even romantic relationships of couples.

That said, it is worth mentioning that stress is unlikely to be the only reason for infertility issues. However, stress usually exacerbates all other reproductive problems and makes them very hard to manage. The emotional load is, in fact, one of the least acknowledged side effects of stress. A lot of women who are treated for fertility issues complain about being stressed. And due to this stress, some of them even give up on their treatment. This is a direct indication that mental health and fertility work in tandem.

The main point is that fertility is more than just hormones or medical intervention; it is the overall well-being that matters. Changing stress levels by having good sleep, exercising regularly, practicing mindfulness, or even getting professional help can have a great impact. In a generation that is always switched on, learning how to slow down might be one of the most important steps toward improving fertility.

Spending hours at work is one thing, but spending countless hours at the same desk just to meet deadlines is a habit that not only takes a toll on mental health but also on physical well-being. That being said, the rising incidence of spine problems is concerning—once a problem of the elderly, it is now affecting younger people as well. However, due to the age factor, several people tend to ignore spine problems, but they continue to worsen silently. In such a scenario, early and regular health checks can help prevent pain, stiffness, and long-term disability.

Dr Harshal Bamb, Senior Consultant and Spine Surgeon at Gleneagles Hospital, Parel, listed some of the key tests for the spine that can help with the early diagnosis of health problems. It is time to focus on spine health and improve quality of life.

Why have spine problems become common?

Currently, many people are struggling with spine problems. With long working hours, poor posture, excessive screen time, and a lack of physical activity, spine-related problems can steal peace of mind. Spine problems are conditions that affect the bones, discs, nerves, or muscles of the back and neck. These may include issues such as muscle strain, slipped or herniated discs, cervical or lumbar spondylosis, and spinal deformities such as scoliosis that can interfere with daily activities.

What are the symptoms of spine problems?

It is essential to seek help for signs and symptoms such as back or neck pain, stiffness, tingling or numbness in the arms or legs, reduced flexibility, and difficulty in standing or sitting for long periods. In more severe cases, it can also lead to weakness or nerve compression in patients. Timely awareness and routine checks can help prevent complications such as immobility, pain, nerve damage, and posture problems. If left untreated, spine problems can impact quality of life.

Health tests that can help diagnose spine problems

Dr Bamb, in an interview with Health and Me, spoke about the key spine health checks that can be helpful for people dealing with severe pain and strain.

1. Posture check: The expert will examine regular sitting and standing posture, especially during work hours. So, if you have back pain due to poor posture, then seek immediate help. Posture evaluation is important for everyone.
2. Pain monitoring: The expert will track any recurring back or neck pain instead of ignoring it.
3. Flexibility test: Check your ability to bend, twist, and move without discomfort. Do the range of motion (ROM) test as suggested by the doctor.
4. Nerve symptoms check: Watch for tingling, numbness, or weakness in the limbs. A neurological examination (sensory and motor assessment) will be conducted.

Evaluating lifestyle habits such as long sitting hours, obesity, and lack of exercise is also key to understanding spine health. Spine risk assessment or even musculoskeletal risk screening is also important. So, take these tests and keep your spine healthy.

Just like regular health check-ups for the heart, joint and spine check-ups are also important. Maintaining good posture, staying active, stretching, exercising daily, and seeking timely medical advice can help to protect the spine. Do not engage in strenuous activities mindlessly and pay attention to your spine.
