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.

Bajau Sea Nomads have evolved beyond human limits. But how is that even possible? Remember Charles Darwin's theory of natural selection? The survival of the fittest? This is what kept the Bajau Sea Noamds going, and evolving.

The Bajau people are sea nomads who survive by collecting shellfish from the sea floor. They come from South-East Asia, and study shows that they have developed bigger spleen for diving. They are known as 'Sea Gypsies' and are known to hold their breath for over five minutes, whereas highly trained professionals can hardly hold their breath for three to four minutes. Bajau divers spend hours underwater for fishing. They are also the world's only community of self-sufficient sea nomads, reported The Guardian.

How The Bajau Sea Nomads Evolved: What Does The Study Say?

A study published in the academic journal Cell notes that the effect of their underwater lifestyle reflected on their biology. Their spleens were larger than those of other people from the region.

How The Bajau Sea Nomads Evolved: How Does A Spleen Work?

Tucked just beside the stomach, the spleen is roughly the size of a fist and usually flies under the radar. Its everyday job is to filter old red blood cells from the blood. But under the right conditions, it can also act like a built-in oxygen reserve.

This hidden ability is especially important for the Bajau people, often called “sea nomads,” who live across parts of the southern Philippines, Indonesia and Malaysia. Numbering roughly a million, the Bajau have relied almost entirely on the ocean for generations.

“For possibly thousands of years, they have been living on houseboats, travelling from place to place in the waters of South-East Asia and visiting land only occasionally,” said Melissa Ilardo from the University of Copenhagen, speaking to the BBC’s Inside Science. “Everything they need, they get from the sea.”

How The Bajau Sea Nomads Have Evolved?

The Bajau are known for their extraordinary free-diving abilities. When diving in the traditional way, they spend up to eight hours a day at sea, with around 60 percent of that time underwater. Individual dives can last anywhere from 30 seconds to several minutes, often reaching depths of more than 70 metres.

What makes this even more remarkable is the equipment. Many Bajau divers use little more than a wooden mask or simple goggles and a weight belt. No oxygen tanks, no wetsuits, no modern diving aids.

This lifestyle prompted researchers to ask whether the Bajau body has adapted over time to support such extreme breath-hold diving.

According to Dr Ilardo, the spleen was an obvious place to look. Humans, like many marine mammals, have a natural “dive response” that kicks in when we hold our breath and submerge ourselves in water, especially cold water.

“When this response is triggered, your heart rate slows down,” she explained. “Blood vessels in your arms and legs constrict to preserve oxygen-rich blood for vital organs like the brain and heart.”

The final part of this response involves the spleen.

How The Bajau Sea Nomads Evolved: An enlarged Spleen Boosts Oxygen

The spleen acts as a reservoir for oxygenated red blood cells. When it contracts during a dive, it releases these cells into the bloodstream, giving the body a temporary oxygen boost.

“It’s like a biological scuba tank,” Dr Ilardo said.

For people like the Bajau, who dive repeatedly every day, this spleen contraction can make a crucial difference, helping them stay underwater longer and recover faster between dives.

In short, what seems like an ordinary organ plays an extraordinary role, revealing how the human body can adapt in remarkable ways to extreme environments.

One child in India dies every nine minutes from an infection caused by antibiotic-resistant bacteria, as it becomes one of the top 10 global public health threats, experts warn.

Dr HB Veena Kumari of the Department of Neuromicrobiology, National Institute of Mental Health and Neurosciences, claims: "The Covid-19 pandemic has significantly contributed to rising antimicrobial resistance. The World Health Organisation projects that 10 million deaths will occur annually by 2025."

According to the National Foundation for Infectious Diseases, antibiotic resistance occurs when bacteria in the body learns to withstand and remain unaffected by the medicines (antibiotics) meant to kill them.

In such cases, doctors have to switch to different antibiotics, but these backup medicines might not work as well or might cause more side effects. Additionally, infections may also worsen over time as bacteria can become resistant to all available drugs.

Alarmingly is that these tough, drug-resistant bacteria can spread from one person to another, both in hospitals and at home.

According to Dr TS Balganesh, Gangagen Biotechnologies, nearly 36 percent of haemodialysis patients die from fatal infections, which is second only to cardiovascular diseases as a cause of death.

He tells Deccan Herald: "The risk for infective endocarditis in haemodialysis patients is approximately 18 times higher than in the general population and up to 58 percent of these episodes are caused by a bacteria named 'S aureus', with an in-hospital mortality of more than 50 percent."

What Does WHO Say?

One out of every six serious infections confirmed in labs worldwide last year could not be killed by the antibiotics meant to treat them.

Between 2018 and 2023, the problem of antibiotics failing (called resistance) got much worse. For many common types of germs, resistance went up by 5% to 15% every year. The growing inability of these essential medicines to work is a huge threat to people everywhere.

Which Antibiotics Are People Becoming Resistant To?

The WHO's latest report is the most detailed look yet at this issue. It reports on how much resistance exists across 22 different antibiotics, which include common drugs used to treat everyday illnesses. The report focused on eight common types of bacteria that cause things like:

• Urinary tract infections (UTIs)
• Stomach and intestinal infections
• Dangerous blood infections
• Gonorrhoea

Additionally, Dr Obaidur Rahman of Dr Ram Manohar Lohia Hospital has also warned that the country’s casual use of Azithromycin, sold under brand names such as Zithromax, Azee and Zmax, has worsened its effectiveness and pushed India closer to a major public health challenge.

A drug often prescribed for sore throats and upper respiratory tract infections, Dr Rahman noted that Azithromycin was once effective against Mycoplasma Pneumonia, a bacterium responsible for pneumonia in adults and children.

However, this is no longer the case as India now shows an alarming 80 to 90 percent resistance to the drug when treating infections caused by this bacterium. A medicine that once addressed a wide range of respiratory problems is no longer reliable for many patients.

The surgeon has since urged people to avoid taking antibiotics without proper medical advice. Most seasonal respiratory infections resolve on their own, and unnecessary drugs only add to the resistance problem.

Supreme Court on Friday declared the right to menstrual health as part of the right to life under Article 21 of the Constitution. The court issued a slew of directions to ensure that every school provides biodegradable sanitary napkins free of cost to adolescent girls. The guidelines also ensured that schools must be equipped with functional and hygienic gender-segregated toilets. The Court directed the pan-India implementation of the Union's national policy, 'Menstrual Hygiene Policy for School-going Girls' in schools for adolescent girl children from Classes 6-12.

Supreme Court Declares Menstrual Hygiene As Part Of Right To Life: Here Are the Directions

A bench comprising Justice JB Pardiwala and Justice R Mahadevan passed the following directions:

• All States/UT must ensure that every school, whether government-run or privately managed, in both urban and rural areas, is provided with functional gender segregated toilets with usable water connectivity.
• All existing or newly constructed toilets in schools shall be designed, constructed and maintained to ensure privacy and accessibility, including by catering to needs of children with disabilities.
• All school toilets must be equipped with functional washing facilities and soap and water available at all times.
• All states/UTs must ensure that every school, whether government-run or privately managed, in both urban and rural areas, provide oxo-biodegradable sanitary napkins manufactured in compliance with the ASTM D-6954 standards free of cost. Such sanitary napkins must be made readily accessible to girl students, preferably within toilet premises through sanitary napkin vending machines or, where not visible, at a designated place.
• All States/UTs must ensure that every school, whether government-run or privately managed, in both urban and rural areas establish menstrual hygiene management corners. It must be equipped with spare innerwears, uniforms, disposable pads and other necessary materials to address menstrual urgency.

The court also issued directions for the disposal of sanitary waste. Justice Pardiwala said, "This pronouncement is not just for stakeholders of the legal system. It is also meant for classrooms where girls hesitate to ask for help. It is for teachers who want to help but are restrained due to a lack of resources. And it is for parents who may not realise the impact of their silence and for society to establish its progress as a measure in how we protect the most vulnerable. We wish to communicate to every girlchild who may have become a victim of absenteeism because her body was perceived as a burden when the fault is not hers."

Why Is This Judgment So Important?

In India, menstruation is still seen as taboo. In fact, there is a lot of shame around it. Menstrual shame is the deeply internalized stigma, embarrassment, and negative perception surrounding menstruation, which causes individuals to feel unclean, or "less than" for a natural biological process. This judgment thus is an effort to do away with the shame rooted in cultural, social, and religious taboos, which is often the reason why many girls drop out, or due to lack of awareness, develop health adversities.
