Metabolism plays a big role in our health, it’s not just about helping your digestive system work smoothly, but the way your body breaks down the food and helps nutrients get absorbed into the body that matters. But often due to one reason or the other, your metabolism can slow down, which then causes issues with people. Many people think that the reason they may be gaining weight could be because of their poor metabolism, so how does one go about fixing this issue and how do you even know that the fault lies with your metabolism.

To understand why your metabolism may be slowing down, we must understand what role it exactly plays. Metabolism is the process your body uses to turn food into energy. It's essential for everything from breathing and digestion to keeping you warm. Several things affect how fast your metabolism works, including your genes, health, and lifestyle. A slow metabolism means your body burns fewer calories, which can lead to tiredness, dry skin, weight gain, and cravings.

Why Does Your Metabolism Slow Down?

There can be many reasons why your metabolism may be slowing down. You inherit some of it, and it tends to slow down as you age, often due to changes in your body and less muscle. Men and women have different metabolisms because of body size, makeup, and hormones. What you eat matters too – not enough healthy food or a very low-calorie or high-fat diet can slow it down. A lazy lifestyle, lack of sleep, and stress can also make your metabolism sluggish. Certain health problems like diabetes or an underactive thyroid, and even environmental factors, may also play a role.

Signs You Need To Improve Your Metabolism

While these are some common signs, it is best to visit a healthcare professional and ask for their opinions before you try a solution. There are many underlying reasons as to why you are experiencing slow metabolism, it can also be a side-effect of some medicine. A healthy lifestyle goes a long way, especially for people who already have digestive issues, kidney or even mental health issues like stress and anxiety.

Constant Fatigue

Feeling tired all the time, even without a good reason, could mean your metabolism is slow. A slow metabolism means your body breaks down food into energy slowly, leaving you with low energy levels. You might feel sluggish or get tired easily throughout the day. Changes in what you eat or your body composition (how much fat and muscle you have) can also make you feel more tired.

Dry Skin

Dry skin is common in winter, but if you have it all the time, it could be a sign of a slow metabolism. Thyroid hormones help control your metabolism and also keep your skin hydrated. If your thyroid isn't working right and your metabolism is slow, your skin might get very dry.

Weight Gain

If you're eating healthy and exercising but still gaining weight, a slow metabolism could be the problem. A slow metabolism doesn't turn food into energy quickly, so you burn fewer calories. Extra calories are stored as fat, making it hard to lose weight.

Feeling Cold

Feeling cold even when it's not cold outside can be a sign of a slow metabolism. Your body generates heat through metabolism. If your metabolism is slow, your body temperature might be lower. Some studies show that people with an underactive thyroid or obesity may have lower body temperatures because of a slow metabolism. This can be because of problems with thyroid hormones, which help your body make heat.

Food Cravings

Craving sugary or fatty foods can be a sign of a slow metabolism. Studies show that cravings are related to metabolic health. This is especially true for people who don't eat enough healthy foods, have bad eating habits, or have low muscle mass and high fat mass. Cravings might also mean your body isn't getting enough energy from the food you eat, so it wants more energy.

Mood Swings

Everyone has mood swings sometimes. But if you have them often, it could be from a slow metabolism. Low energy and hormone problems that come with a slow metabolism can make you irritable and frustrated. Some older research also suggests a link between mental health issues and a slow metabolism.

Digestive Problems

Digestion and metabolism are connected. Digestion breaks down food, and metabolism turns it into energy. If your metabolism changes, like slowing down, it can affect your digestion. A slow metabolism can cause constipation, bloating, or diarrhea.

A team of UK scientists has developed a non-invasive brush biopsy test that can detect oral cancer within just 60 minutes, potentially transforming the way the disease is diagnosed.

Researchers from Queen Mary University of London say the test could prevent more than 90% of unnecessary scalpel biopsies, reducing pain, infection risk and diagnostic delays. The findings were published in the journal Biomarker Research.

Early diagnosis of oral squamous cell carcinoma (OSCC) is critical. However, most oral potentially malignant disorders (OPMDs) are benign, meaning many patients undergo invasive scalpel biopsies that ultimately show no cancer.

These procedures can be painful, carry a risk of infection and, in areas such as the gums, can be difficult to perform and may damage the underlying tooth or bone.

Beyond diagnosis, researchers say the test could also help monitor patients with persistent OPMDs over time. Because the test is non-invasive and repeatable, it can be used for regular surveillance, improving the chances of detecting malignant transformation at an early stage, when treatment is most likely to be successful.

How Does The Brush Test Work?

The newly developed brush biopsy requires only a simple swab of the mouth, without removing any tissue. According to the researchers, the test can identify low-risk patients and potentially spare more than 90% of them from unnecessary invasive tissue biopsies. Another advantage is speed—the results are available within one hour.

"This test gives clinicians a rapid, accurate, and non-invasive way to triage patients, and crucially, it can be repeated. That means we can now monitor patients with persistent pre-malignant lesions regularly and systematically — and pick up cancers much earlier than we would have been able to before," said Muy-Teck Teh, Professor of Molecular Oral Oncology at Queen Mary.

How Was The Study Conducted?

The study is the largest of its kind, involving more than 1,000 samples from 545 patients. The team collected brush biopsies from the mouths of 545 patients with lesions that could potentially be cancerous.

The test was found to have an overall accuracy of 95.5 percent, with false-positive and false-negative rates of less than 5 percent. The results were available within an hour.

The latest study builds on an earlier version of the test, qMIDS-V2, which required a 1 mm microbiopsy and had already been validated using more than 530 samples from the UK, India and China.

The new qMIDS-V3 requires only a brush swab of the mouth, with no tissue removal, yet achieves test performance comparable to its microbiopsy predecessor.

Oral Cancer Remains A Growing Global Burden

According to Global Burden of Disease data, lip and oral cancer are among the world's fastest-growing causes of early death.

More than 10,000 people in the UK were diagnosed with oral cancer last year, while 3,637 people died from the disease, according to the charity Mouth Cancer.

Worldwide, oral cancer affects around 650,000 people every year. Major risk factors include tobacco use, smoking, alcohol, HPV infection and sun damage. More than 53% of mouth cancers are diagnosed at Stage IV, when the disease is at its most advanced.

What does it take to become a CEO? Decades of hustle and hard work. J Michael Prince, CEO of US Polo Assn., probably had the same idea. But after years of toiling away, he landed at a startling realization – he could have done it all without pushing himself to the limit. He recently opened up about the importance of work-life balance and setting aside time for yourself at the end of the day.

Work-Life Balance And Burnout

In a conversation with Fortune, Prince said that he now makes a conscious effort to avoid contacting his employees outside office hours unless it’s an emergency.

He said, “One thing I try to respect is—and this never really happened to me throughout my career—unless there’s something major going on, I try to leave people alone in the evenings, so you rarely ever get an email or text from me after the office.”

He spoke about the importance of personal time and allowing oneself to reset after a workday. “I leave the office, and I really try to respect people’s weekends, because I feel like that’s your family time, that’s your personal time, that’s your friendship time, that’s your time to reset, recharge spiritually, mentally, physically, emotionally,” he added.

HealthandMe spoke to Dr. Samant Darshi, Consultant- Psychiatrist & Neuromodulation Expert, Director - Psymate Healthcare, Noida, about the importance of maintaining work-life balance to prevent burnout.

The expert says that it is necessary to maintain a balance between work and life since it helps in enhancing health and well-being, reduces stress, increases productivity, and develops meaningful relationships. Maintaining a balance would lead to higher job satisfaction and happiness in life.

Dr Darshi says, “Work-life imbalance increases levels of stress and anxiety and causes emotional exhaustion. Persistent stress can result in depression, insomnia, hypertension, decreased immunity, and cardiovascular diseases. Lack of rest and time for leisure activities causes a loss of concentration and low self-esteem, thus making everyday life more stressful and challenging.”

Tackling Burnout

Prince admitted he didn’t always give importance to work-life balance. Earlier in his career, he regularly worked 90-hour weeks, stayed up through the night, and rarely slowed down. Looking back, he said he could have achieved the same goals without sacrificing so much of his health and time.

Prince said, “I could have eaten differently, I could have been a little more thoughtful about my sleep, about my routine around working out, my travel.”

According to Dr Darshi, work-life imbalance leads to a feeling of burnout. Experiencing constant stress, unrealistic expectations, and lack of time for leisure gradually exhausts physical and emotional resources. Eventually, motivation tanks, productivity drops, fatigue, detachment, frustration, and inability to function increase.

He explains, “Burnout adversely impacts the mental state of an individual by causing symptoms such as emotional fatigue, anxiety, depression, irritability, and hopelessness. It causes demotivation and loss of focus in addition to making individuals feel insecure. If not addressed, it may adversely impact personal relationships, affect work, and cause chronic health conditions.”

While many people blame pollen or changing weather for their allergies, health experts say hidden allergens inside the home may be just as responsible. On the occasion of World Allergy Day on July 8, doctors highlighted that dust mites, mold, pet proteins, and household products are among the often-overlooked triggers that can affect indoor air quality and contribute to persistent allergy symptoms.

They also cautioned that chronic allergies should not be dismissed as a minor inconvenience, as they can affect sleep, respiratory health, and overall quality of life.

What Is A Chronic Allergy?

Dr. Sanjiv Dang, ENT & Allergy Specialist, Apollo Hospitals, Delhi, told HealthandMe that allergy symptoms lasting for weeks, months, or throughout the year may indicate chronic allergies and should not be ignored.

He explained that "allergies occur when the immune system overreacts to substances such as dust mites, pollen, mold, pet dander, or certain foods, releasing histamine". This can lead to symptoms including sneezing, nasal congestion, a runny nose, itchy eyes, and throat irritation.

Prof. (Dr.) Dwaipayan Mukherjee, Consultant ENT Surgeon, Kolkata, told HealthandMe that flower pollen is often blamed for seasonal allergies, but it is usually not the main culprit because its grains are larger and less likely to remain airborne. Instead, he said most seasonal allergies are caused by microscopic airborne pollen from grasses, weeds, and trees.

Dr. Mukherjee, also the Past President of the Association of Otolaryngologists of India (AOI), added that homes can also harbor numerous microscopic allergens that negatively affect indoor air quality. Common triggers include:

• Dust Mites

• Mold

• Pet Proteins

Household Products and Indoor Plants

Cleaning sprays, air fresheners, scented candles, and similar products may emit compounds that irritate sensitive airways and worsen allergy symptoms despite creating the impression of a cleaner environment.

Indoor plants can also become a source of allergens if mold develops in damp potting soil or if certain plants release pollen. Outdoor pollen from trees, grasses, and weeds can also enter homes on clothing, shoes, and hair before settling on indoor surfaces, the experts said.

Dr. Dang said chronic allergies are more than just a runny nose. Persistent nasal congestion can disrupt sleep, leading to snoring, frequent awakenings, daytime fatigue, poor concentration, reduced productivity, and mood changes.

He added that ongoing allergic inflammation can affect both the upper and lower airways. People with chronic allergies are at a higher risk of developing asthma, while those who already have asthma may experience worsening symptoms such as coughing, wheezing, chest tightness, and shortness of breath.

Chronic allergies can also block normal sinus drainage, increasing the risk of recurrent sinus infections. Facial pressure, headaches, post-nasal drip, persistent congestion, and a reduced sense of smell may all indicate allergy-related sinus problems.

How To Prevent Chronic Allergies

The experts advised relying solely on over-the-counter medications, saying they may provide temporary relief without addressing the underlying cause. They noted that prolonged use of certain nasal decongestant sprays can even worsen congestion over time, and also recommended consulting a healthcare professional if allergy symptoms persist for several weeks or throughout the year.

To help manage chronic allergies, the experts recommended:

• Improving ventilation indoors.

• Controlling indoor humidity.

• Using HEPA air cleaners.

• Cleaning the home regularly.

• Eliminate excess moisture.

• Identifying and reducing exposure to allergy triggers.

• Controlling mold growth indoors.
