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.

Cancer is one of the most dreaded diseases. It is characterised by a malignant tumor that obstructs the normal functioning of organs. According to a recent analysis from the World Health Organisation (WHO), more than a third of cancer cases in the world are preventable. Cervical, stomach, and lung cancers make up half of the cases. This implies that millions of such deadly cases in the world can be prevented with behavioural changes, timely medical intervention, reduced occupational risks, and an ability to tackle environmental pollutants. It turns out that most preventable cancers can be avoided by making two simple lifestyle changes.

Preventable cancers in the world

Researchers say that addressing preventable causes represents one of the most powerful opportunities to reduce the global cancer burden. The analysis also noted that, in 2022, there were approximately 19 million new cases of cancer, and 38 per cent were related to 30 modifiable risk factors. The most common modifiable risk factors are:

1. High BMI
2. Smoking
3. Insufficient physical activity
4. Alcohol intake
5. Smokeless tobacco
6. Air pollution
7. Exposure to infectious agents
8. Suboptimal breastfeeding
9. Occupational exposures

What are the preventable risk factors for cancer?

The most common preventable risk factor, however, was smoking tobacco. It is associated with 15 per cent of all cancer cases in a year. In men, the risk was significantly higher. Smoking contributed to 23 per cent of the new cancer cases globally in men that year. However, smoking alone was not the only cause; air pollution, depending upon the region, played a huge role. In East Asia itself, 15 per cent of lung cancer cases in women were attributed to air pollution. In Western Asia and Northern Africa, 20 per cent of lung cancer cases in men were due to air pollution.

After smoking tobacco, the next key lifestyle risk factor was drinking alcohol. It accounted for 3.2 per cent of all cancer cases—approximately 7 lakh. As per researchers’ estimates, drinking alcohol and smoking tobacco account for about 48 per cent of all preventable cancer cases. Infections, however, were associated with 10 per cent of new cancer cases. Among women, the largest share of these cases was attributed to high-risk human papillomavirus (HPV), which contributes to cervical cancer cases. However, with the HPV vaccine being more accessible, cervical cancer cases have reduced.

Can smoking give you stomach cancer?

Stomach cancer cases are higher among men and are mostly associated with inadequate sanitation, smoking, infections, and poor access to clean water. A first-of-its-kind analysis, this study helps show how much cancer risk comes from preventable causes. By examining these patterns, countries can be alerted to work towards preventing cancers in the first place by taking appropriate steps.

Researchers also mentioned in their paper that 4 in 10 cancer cases in the world in 2022 could have been prevented by eliminating the risk factors considered in the study. The study was published in the Nature Medicine journal.

Sleep is a very crucial part of one's life, and it can affect one's life as a whole. The sleep cycle and duration can determine a lot about one's physical and emotional well-being. Even biological aging is also immensely affected by the right amount of sleep, according to a recent study. The aforementioned research was published in Nature, and as per it, getting too little or too much sleep may speed aging in the brain and other body organs as well.

There were several studies that have been done on the same topic, and many of them concluded that getting less sleep can cause the speeding of one's biological age. Although this new study has come up with a new finding, and it went further than the previous studies on the same topic, the research shows that getting more sleep can also lead you to the same situation, and your biological aging speed can go higher due to it.

The lead study author, Junhao Wen, PhD, assistant professor of radiological sciences at Columbia University, said, “Sleep is fundamental for healthy aging and longevity. More importantly, it is potentially modifiable." He added, “In this study, we measure biological aging clocks across organs to link these clocks with sleep duration.”

The biological age is inherently different from chronological age, which is measured by the number of years one is alive, but on the other hand, biological age measures how quickly your cells and tissues are aging. Researcher Junhao Wen has done his research with different aging clocks, and these clocks are scientific, computational models that estimate a person’s biological age and how they are aging faster or slower than their chronological age.

Wen and his colleagues assessed the relationship between a person’s self-reported sleep duration and their biological age, using 23 aging clocks across 17 organs. The research defined too little sleep as less than 6 hours and too much sleep as more than 8 hours. The study concludes that, in general, people who slept too little or too much showed signs of faster biological aging than those who reported sleeping between 6.4 and 7.8 hours each day.

The same study also sheds light on the relationship between sleep and chronic diseases. The research suggests that a connection exists beyond brain influence. Notably, less sleep causes disorders like depression and anxiety disorders. Other possible conditions related to it are obesity, type 2 diabetes, hypertension, ischemic heart disease, and heart arrhythmias. On the other hand, longer sleep is associated with depression and illness.

Magic mushroom, a fascinating name, but the reason behind this naming is solely due to an active compound in that fungus called psilocybin. Notably, a single dose of it can easily reduce the nerve pain for months, thus has wide and effective use in painkillers according to a study recently done by the researchers from the University of Reading. This crucial study was published in Communications Biology.

The researchers used rats as test subjects to find this information. They injected psilocybin into mice with nerve damage. But within two hours, researchers found that the pain-relieving effect of psilocybin starts to relieve the pain in mice that had excruciating pain due to nerve damage. Though this was by no means the biggest finding of the study, it was also seen that the effect of the compound lasted for several weeks.

How Does Psilocybin Work As A Pain Reliever?

There is a very interesting explanation behind the long-lasting effect of Psilocybin. The active compound does not block the pain signal to the brain like other common pain relievers; instead, Psilocybin is likely to restructure the way the brain's pain-processing networks operate, which in turn ensures long-lasting effects of the compound even long after it exits the body.

What Is The Most Significant Finding Of The Study?

The study finds a great connection of mutual compatibility between psilocybin and gabapentin. Notably, gabapentin is a well-known drug commonly prescribed for nerve pain. In the aforementioned study, the researchers noticed that when gabapentin was given along with psilocybin, it produced pain relief lasting up to four days, but the effect when gabapentin was given alone was far weaker.

Dr Maria Maiarú, senior author from the University of Reading, said, "Millions of people live with nerve pain that their medication simply does not control well enough, and the medicines we do have can cause serious side effects or lead to addiction. What is exciting here is that psilocybin does not just reduce pain on its own. It appears to reset the brain's pain networks in a way that makes existing treatments significantly more effective. For patients who have run out of options, that could be genuinely transformative."

What Are The Other Crucial Findings In The Research?

Although initially the tests were done on the male mice, later on, the same compound was also injected into the bodies of female mice, and in both cases, the effect was complete success in achieving pain relief. The whole study was done with the aim of minimizing distress by using the 3Rs principles of Replacement, Reduction, and Refinement.

Why Is It called A Magic Mushroom?

The name is the direct result of its active compound, Psilocybin, which, when injected, can cause dream-like hallucinations, euphoria, and profound shifts in perception, mood, and consciousness.
