Anxiety is seen as an obstacle to success. It is a thought that always lingers in your mind before you start to do something. If you are doing something new or trying to do something that you have already done it in your life and have bad memories with. This thought creeps in. This thought that sometimes sends chills down your spine, makes you shiver, or that makes you feel like you cannot breathe, as if someone has put a huge rock on your heart is what defines anxiety. However, emerging research suggests that it can in fact, serve as a valuable tool for focus, motivation and problem solving. Studies on performance and stress, including the widely known Yerkes-Dodson curve, indicate that moderate levels of anxiety can enhance productivity, while both excessive and insufficient anxiety can hinder it.

The Yerkes-Dodson curve demonstrates that when anxiety is too high, it can become paralyzing, preventing individuals from taking action. On the other hand, very low anxiety can lead to complacency, reducing motivation and attention to detail. The ideal state falls somewhere in the middle, where anxiety signals importance, sharpens focus, and encourages preparation.

This perspective challenges the common belief that anxiety should always be suppressed. Instead, researchers argue that learning to harness anxiety can be beneficial. Studies have shown that people experiencing moderate anxiety often generate more creative solutions to problems compared to those who remain entirely calm.

How Can You Use Anxiety To Your Benefit?

Anxiety can serve as a sort of increased awareness, motivating people to take action in critical situations. Medical decision-making research show that concerned people are more likely to follow up on health issues, stick to treatment plans, and aggressively seek medical help. For example, studies on heart transplant patients show that people with moderate levels of anxiety are more likely to seek adequate care, which leads to improved survival rates.

The same strategy is used to address everyday difficulties. Anxiety tells the brain that something is important and requires effort. Anxiety can encourage you to be prepared and attentive, whether you're preparing for a presentation, making a critical life decision, or dealing with an uncertain situation.

Is There A Thin Line Between Anxiety That Helps And That Harms?

Despite its potential benefits, anxiety can become debilitating when it causes what researchers term “functional impairment.” This occurs when excessive worry prevents individuals from fulfilling their daily responsibilities, whether in work, relationships, or personal well-being.

One method for distinguishing between helpful and harmful anxiety is cognitive reframing—shifting the perspective on stressors. Studies suggest that those who reframe anxiety as a performance-enhancing tool rather than a hindrance experience less distress and greater effectiveness in high-pressure situations. By viewing anxiety as a source of energy rather than a threat, individuals can improve their ability to navigate challenges.

Research on stress resilience indicates that experiencing a moderate amount of adversity in life can lead to stronger coping skills. Longitudinal studies on both humans and animals suggest that those who have faced and overcome moderate difficulties—such as personal loss or professional setbacks—tend to develop greater mental fortitude.

One study found that individuals who had endured a small number of adverse events exhibited better overall mental health than those who had either faced extreme hardship or had led relatively stress-free lives. This pattern aligns with the concept of "stress inoculation," where manageable levels of stress act as a form of psychological training, making individuals more resilient to future challenges.

So, What Can You Do?

Rather than attempting to eliminate anxiety, researchers suggest acknowledging it as a natural response that can be channeled productively. Psychological studies indicate that when people view their physiological responses—such as increased heart rate and adrenaline surges—as performance enhancers, their actual outcomes improve.

For instance, in high-stakes situations like public speaking or athletic competitions, individuals who interpret nervousness as a sign of readiness rather than fear tend to perform better. Physiologically, the body's response to excitement and fear is similar; the key difference lies in perception.

Research suggests that those who embrace a mindset of "anxiety as fuel" experience improved cognitive and physical performance. This approach aligns with studies showing that moderate stress prompts the release of hormones that enhance alertness and problem-solving ability, whereas overwhelming stress triggers a flood of cortisol, which can impair decision-making.

A new study suggests that drinking sugary drinks can increase anxiety, among other mental issues, in adolescents by 34 percent.

Sugary drinks are known to be more harmful due to their low fiber, protein, or fat, which typically slow down digestion in solid foods. This means liquid sugar gets into your bloodstream very quickly, causing a sudden jump in blood sugar and insulin levels.

Hyper-fast intake of such drinks can also make it hard for your liver to process the sugar, especially the fructose part. n large amounts, fructose turns into fat in your liver. This buildup of fat is linked to metabolic problems that lead to Type 2 diabetes.

Apart from this, a Bournemouth University, UK literature review analyzed people aged between ten and 19 who drank fizzy drinks, colas, sweetened fruit juices, sweetened milk drinks, energy drinks, and sweetened tea or coffee and found multiple links between the beverages and anxiety diagnosis.

The gut-brain axis — the connection between the brain and the gut — may help explain the link between sugary drinks and anxiety. But gut health is influenced by many factors, including diet, stress, and sleep, which are also linked to anxiety.

Overall, the study suggests that cutting back on sugary drinks could help support teenagers’ mental health. While many studies have looked at how reducing sugary drinks improves physical health, more research is needed to see if it also benefits mental health.

WHO Asks Countries To Tax Sugary Drinks

The World Health Organization is asking countries across the world to increase taxes on sugary drinks and alcohol to reduce cases of chronic conditions such as Type 2 diabetes, obesity, heart disease and fatty liver.

In a January 13 virtual conference, WHO Director-General Dr Tedros Adhanom Ghebreyesus said: "Health taxes have been shown to reduce consumption of these harmful products, helping to prevent disease and reduce the burden on health systems.

"At the same time, they generate an income stream that governments can use to invest in health, education and social protection."

According to a recent report on sugar-sweetened beverages taxes, at least 116 countries tax sugary drinks, including sodas or carbonated canned drinks, but other high-sugar products, such as 100 per cent fruit juices, sweetened milk drinks and ready-to-drink coffees and teas, escape taxation.

Additionally, another report on alcohol taxes shows that even though 167 countries levy taxes on liquor, wine and beer, alcohol has become more affordable or remained unchanged in price in most countries since 2022, as taxes do not get adjusted for inflation and income growth.

How To Cut Back On Sugary Drinks?

Sugary drinks can feel addictive. If you find yourself hooked, try to slowly reduce how much you drink, just like you would with alcohol or tobacco. It helps to plan ahead for when you usually crave a soda.

You can start by mixing plain sparkling water with an equal amount of fruit juice or soda. Then, week by week, slowly reduce the amount of the sugary drink until you're mostly just drinking sparkling water. If it helps, add a little lemon or lime juice for flavor.

Participating in ultra-marathons can cause damage to your red blood cells' flexibility and hamper their oxygen-carrying capacity, a study suggests.

A study published in the American Society of Hematology’s journal Blood Red Cells & Iron notes that extreme forms of exercise may harm, rather than support, overall health.

In the case of ultra-marathons, runners experience breakdown of normal red blood cells during races. Over time, their red blood cells become less flexible and potentially reduce their ability to efficiently carry oxygen, nutrients and waste products throughout the body.

Travis Nemkov, associate professor in the department of biochemistry and molecular genetics at the University of Colorado Anschutz and the study’s lead author said of the results: “Participating in events like these can cause general inflammation in the body and damage red blood cells.

“Based on these data, we don’t have guidance as to whether people should or should not participate in these types of events; what we can say is, when they do, that persistent stress is damaging the most abundant cell in the body.”

Red blood cells transport oxygen and waste throughout the body and must be flexible enough to squeeze through small blood vessels. When red blood cells become inflexible or rigid, they lose their ability to deform and navigate through the body's smallest vessels, leading to impaired oxygen delivery, blockage of blood flow, and rapid destruction by the body's filtration system.

This can lead to low hemoglobin and anemia which can pave the way for diseases like Sickle Cell Disease (SCD), thalassemia, hereditary spherocytosis, and, in some cases, the "storage lesion" of blood in transfusion banks.

What Is Low Hemoglobin?

Hemoglobin is the oxygen-carrying protein in red blood cells. Adequate hemoglobin levels are essential for keeping organs and tissues properly supplied with oxygen. Without enough of it, the body begins to struggle to meet its basic energy needs.

Low hemoglobin is usually identified through a blood test. It is most often measured as part of a complete blood count (CBC), which checks different components of the blood, including red and white blood cells and platelets, as per Healthline.

While exact reference ranges can vary slightly between laboratories, healthy adult hemoglobin levels usually fall within the ranges listed below. These values are different for babies, children, and teenagers:

• Normal Hemoglobin Count in Grams per Deciliter (g/dL) | Normal Hemoglobin Count in Grams per Liter (g/L)
• Adult Males: 13.8–17.2 | 138–172
• Adult Females: 12.1–15.1 | 121–151

Any reading below these ranges in adults is considered low hemoglobin and suggests that oxygen delivery in the body may be reduced, as per Mayo Clinic.

Is Low Hemoglobin Ever Dangerous?

Low hemoglobin is not always an emergency. In many cases, it develops gradually and can be managed with treatment. That said, very low levels can be dangerous. A hemoglobin level below 5.0 g/dL has been linked to serious complications, including heart failure and even death. Levels under 6.5 g/dL may be considered life-threatening and require urgent medical care.

What Causes Low Hemoglobin?

One of the most common reasons for low hemoglobin is anemia. Anemia occurs when the body does not have enough healthy red blood cells. The most frequent type is iron-deficiency anemia, which develops when the body lacks enough iron to produce hemoglobin.

Other forms of anemia include pernicious anemia, which occurs when the body cannot properly absorb vitamin B12, and hemolytic anemia, where red blood cells are destroyed faster than they are produced.

Low hemoglobin can also be caused by:

• Blood loss or internal bleeding
• Certain cancers, including leukemia, lymphoma, multiple myeloma, and cancers that spread to the bone marrow
• Chronic kidney disease
• Deficiencies of folate or vitamin B12
• Hypothyroidism
• Liver disease
• Poor nutrition or malnutrition
• Myelodysplastic syndrome (MDS)
• Sarcoidosis
• Sickle cell disease and other inherited blood disorders
• Systemic lupus erythematosus
• Thalassemia, a genetic condition that reduces hemoglobin production
• Excess fluid in the body
• Cancer treatments such as chemotherapy and radiation can also lower hemoglobin levels, particularly in adults over the age of 65.

What Does Having Low Hemoglobin Feel Like?

• Feeling dizzy or lightheaded, sometimes fainting
• Muscle weakness
• Ongoing fatigue or low energy
• Pale or washed-out skin
• Frequent headaches

How Is Low Hemoglobin Treated?

Treatment depends entirely on what is causing the low hemoglobin. A healthcare provider will first identify the underlying reason before recommending treatment. Possible treatment options include:

• Blood transfusion: If hemoglobin is low due to heavy blood loss, a transfusion may be needed to restore levels quickly.
• Vitamin supplements: When nutritional deficiencies are the cause, iron, folate, or vitamin B12 supplements are often prescribed. Hemoglobin levels usually begin to improve within six to eight weeks.
• Intravenous (IV) therapy: In cases where iron or B12 levels need to be raised rapidly, IV infusions may be recommended.
• Bone marrow transplant: This may be required when low hemoglobin is linked to certain cancers or bone marrow disorders.

If a long-term illness is responsible, managing that condition becomes the key part of treatment, alongside monitoring hemoglobin levels regularly.

Researchers from Denmark and Australia have discovered a new virus in the gut that can contribute to the development of colorectal cancer in the body, one of the leading causes of death in the world.

Using genetic sequencing, researchers studied the gut bacteria of cancer patients in a large Danish study and found that Bacteroides fragilis, an anaerobic, gram-negative, pleomorphic to rod-shaped bacterium, often carried a bacteriophage — a virus that infects and reproduces inside bacteria.

This allows it to produce a toxin (BFT) in the colon, promoting chronic inflammation, cell proliferation and tumor growth in the region.

People with colorectal cancer were twice as likely to have this bacteriophage in their gut bacteria. The virus also appears to be previously unknown and does not match any recorded type so far.

Although the first finding came from a small group, it was later confirmed in a larger study of 877 people with and without colorectal cancer. The results suggest that viruses hiding inside B. fragilis may play a role in cancer development.

Microbiologist Flemming Damgaard, from Odense University Hospital in Denmark: "It has been a paradox that we repeatedly find the same bacterium in connection with colorectal cancer, while at the same time it is a completely normal part of the gut in healthy people.

"We have discovered a virus that has not previously been described and which appears to be closely linked to the bacteria we find in patients with colorectal cancer."

What Is Colon Cancer?

Colon cancer develops from polyps in the colon or rectum, often taking years to show symptoms. The cancer begins when small growths called polyps form on the inner lining of the colon or rectum. Over time, changes in the DNA of these cells can cause the polyps to become cancerous.

As abnormal cells multiply, they replace healthy cells and eventually form a mass known as a tumor. This process develops slowly, often taking up to ten years for a precancerous polyp to turn into cancer and begin showing symptoms.

The American Cancer Society notes that colorectal cancer impacts around 1.9 million people every year.. In India, it is the fourth most common cancer among both men and women. In 2022, there were 64,863 new cases and 38,367 deaths.

Projections suggest that incidence will continue to rise by 2026, reflecting both lifestyle changes and improved detection.

Colon cancer can be difficult to detect because it often develops without obvious symptoms. According to experts , these are the three things you should do to protect yourself:

1. Timely risk screening

2. Knowing your cancer family history

3. Acting on early symptoms

What Early Symptoms Should You Look Out For?

Colon cancer rarely announces its presence with dramatic symptoms. More often, it whispers — through changes in bowel habits, subtle abdominal discomfort, or unexplained weight loss.

Some of the most commonly missed early signs include:

• Persistent changes in bowel movements: Chronic constipation or diarrhea often dismissed as dietary effects.
• Blood in stool: Bright red or dark blood should not be ignored.
• Unexplained weight loss: Especially when unintentional.
• Abdominal cramps or bloating: Misinterpreted as common digestive issues.

Persistent changes in bowel habits, especially if they last more than a few days, must be taken seriously. Narrow or ribbon-shaped stools may indicate a tumor partially blocking the colon.
