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.
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.
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.
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 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.
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 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.
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.
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.
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 27-year-old woman in US' state of Arizona suffered a cardiac arrest after using kratom, an over-the-counter supplement she purchased at a local gas station.
Amanda Goodsell, who had never taken kratom before, suffered a cardiac arrest after nearly a week of using the supplement and is now on life support, according to her family.
The mother of 3½-year-old twins tried the kratom gummies at the suggestion of her husband, Mike Goodsell, while seeking relief from persistent leg pain.
“Everybody knew what Kratom was. So I was like, well, okay, well, here, just take this. You could just buy it at the gas station. It’s not going to hurt you,” Mike Goodsell was quoted as saying to the media.
Nearly a week later, Mike found his wife unresponsive in their bed, and rushed her to the hospital, where she was placed on life support
“She like, was like red and her lips were blue, and she was foaming. So I like jumped out of bed. I grabbed her, and then (I) was trying to wake her up,” he said.
“They had to have her on a ventilator to help her breathe. And then they had to put her on a bunch of medications because her heart percentage was at 15%,” Mike added.
After spending two weeks in the hospital, Amanda Goodsell's condition began to improve. Although she has shown significant improvement, as per the doctors she will need a defibrillator and heart medication for the rest of her life.

Kratom is a plant-based substance derived from the Mitragyna speciosa tree, native to Southeast Asia. Traditionally used in countries such as Thailand and Malaysia for pain relief and increased energy, it has gained popularity in the US as an over-the-counter supplement.
Kratom is sold in multiple forms, including powders, capsules, teas, drinks and gummies.
Although it remains legal in many parts of the US, the Food and Drug Administration (FDA) has classified kratom as a "drug of concern" and has not approved it for any medical use.
According to the Substance Abuse and Mental Health Services Administration's National Survey on Drug Use and Health, an estimated 1.7 million Americans aged 12 and older used kratom in 2021.
The substance, sometimes referred to as "gas-station heroin," is banned in at least eight US states—Alabama, Arkansas, Connecticut, Indiana, Louisiana, Tennessee, Vermont and Wisconsin. Several other states, including Iowa and Idaho, are considering restrictions or outright bans.

According to a University of Virginia study, there were 43 hospitalizations linked solely to kratom in 2015. By 2025, that number had risen to 538. Researchers said the increase coincided with the emergence of highly concentrated synthetic products, including 7-OH.
The FDA has stated that kratom should not be used as a dietary supplement.
"Kratom is not appropriate for use as a dietary supplement. FDA has concluded from available information, including scientific data, that kratom is a new dietary ingredient for which there is inadequate information to provide reasonable assurance that such ingredient does not present a significant or unreasonable risk of illness or injury."
The agency has warned consumers not to use kratom because of the risk of serious adverse events, including liver toxicity, seizures and substance use disorder (SUD).
The FDA also notes that, in rare cases, deaths have been associated with kratom use, although these cases usually involved other drugs and the contribution of kratom remains unclear.
The agency is also aware of cases involving neonatal abstinence syndrome, in which newborns experienced withdrawal symptoms such as jitteriness, irritability and muscle stiffness following prolonged exposure to kratom during pregnancy.

Brain health is often associated with old age, but according to neurologists, the foundation for healthy cognitive function is laid much earlier.
On World Brain Day, they warned that the 30s and 40s are a crucial period to protect the brain, as lifestyle habits and underlying health conditions can quietly affect memory, concentration, and overall cognitive health.
Speaking to HealthandMe, Dr. Gurucharan Adoor, Neurologist, Apollo Hospitals Bannerghatta Road, Bengaluru, said brain health is closely linked to cardiovascular health. High blood pressure, high cholesterol, and elevated blood sugar can silently damage the brain years before noticeable symptoms appear.
His advice? Make preventive health checks a routine by monitoring blood pressure, blood glucose or HbA1c, cholesterol, weight, and waist circumference—especially for people with a family history of diabetes, stroke, or early heart disease.

Dr. Adoor said sleep is often the first thing people sacrifice during their busiest years, but the brain pays the price.
Irregular sleep schedules, untreated sleep apnea, and repeated nights of poor-quality sleep can lead to mental fatigue, difficulty concentrating, and persistent brain fog. If brain fog continues, he said, it should not be ignored, as it may indicate an underlying health issue that requires attention.
Dr. Bhushan Joshi, Consultant Neurologist, Manipal Hospital, Kharadi, Pune, told HealthandMe that he is "seeing more professionals in their 30s and 40s complaining of brain fog than ever before". According to him, hormonal changes and chronic inflammation are among the common but often overlooked causes.
Dr. Joshi noted that hormonal fluctuations can significantly influence brain function. Women entering perimenopause may experience difficulty concentrating, while others may notice "word retrieval and short-term memory due to changing estrogen levels that influence brain function."
He added that it is not limited to women. Men also undergo age-related hormonal changes that can affect energy levels and cognitive performance. While these changes are often temporary, they can still be distressing.

Dr. Joshi explained that chronic low-grade inflammation can also contribute to brain fog. Conditions such as obesity, diabetes, autoimmune diseases, and persistent infections can trigger inflammatory responses that interfere with the brain's ability to process information efficiently. In some people, inflammation has been linked to reduced attention, poor memory, and diminished mental clarity.
The good news: Simple daily habits can support long-term brain health. Regular physical activity—whether it's walking, cycling, dancing, or strength training several times a week—improves blood flow to the brain, boosts mood, and supports healthy ageing.
Dr. Adoor also recommends limiting unnecessary screen time, taking regular breaks from phones and digital devices, and focusing on one task at a time to reduce mental overload.
Occasionally feeling mentally sluggish is common, but worsening memory problems or cognitive changes that begin interfering with work or daily life should not be ignored, Dr. Joshi said.
He added that these symptoms may stem from treatable conditions such as thyroid disorders, vitamin deficiencies, anxiety, or depression, making timely medical evaluation important.

Insufficient sleep can impact the brain. A good night's sleep allows the brain to repair and even recharge. Poor sleep over time can increase the risk of several neurological disorders and affect overall brain health.
This article helps to understand how poor sleep can take a toll on neurological health. Read on to know more about this and get a sound sleep at night.
Currently, due to hectic schedules, people are now sacrificing sleep to meet work deadlines, study longer, or spend more time on screens. Missing a few hours of sleep once in 2-3 months is harmless.
However, chronic sleep deprivation can not only cause irritation and weight gain but also neurological issues. During sleep, the brain processes memories, repairs nerve cells, regulates emotions, and clears waste products that accumulate throughout the day.
When sleep is disturbed on a regular basis, there can be a risk of neurological problems over time.
If you are one of those who is unable to get a sound sleep at night, then beware. If you are a night owl, then you will have to ensure you sleep well now.
Sleep helps the brain store and organise new information. Lack of sleep can make it difficult to concentrate, learn new skills, and remember important details. Many will also experience poor decision-making.
Poor sleep, especially when associated with conditions like sleep apnoea, can increase blood pressure and reduce oxygen supply, raising the risk of stroke in the near future.
Long-term sleep deprivation may reduce the brain's ability to clear harmful proteins such as beta-amyloid, which are linked to Alzheimer's disease and other forms of dementia.
People who sleep too little or have poor-quality sleep can also suffer from constant headaches and migraine attacks. In people living with epilepsy, inadequate sleep is a common trigger for seizures. Poor sleep increases the risk of anxiety, depression, irritability, and emotional stress.
It is necessary to get at least 7-9 hours of sleep per day. Maintain a consistent sleep and wake-up schedule.
Avoid screens, caffeine, and heavy meals before hitting the sack. Exercise regularly but avoid intense workouts late at night.
Keep your bedroom quiet, cool, and dark so that you can sleep better. Seek help from the doctor if you snore loudly, stop breathing during sleep, or feel excessively sleepy during the day.
So, just like a balanced diet, exercise, and staying stress-free by doing yoga and meditation, getting a good night’s sleep is also important. Sleep well and prevent any neurological issues.
