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.
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.
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.
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 UK woman has claimed that Wegovy and Mounjaro, the blockbuster GLP-1 weight-loss drugs from Novo Nordisk and Eli Lilly, did not help her lose much weight despite more than a year of treatment.
Karen Lay, 56, from Essex, spent £4,000 on the medications, hoping they would help her slim down from 16 stone (224 pounds). However, after 15 months, she lost less than a stone, despite eating very little.
Lay now says the injections were far from a "magic fix" and credits a structured diet for helping her lose two stone, the Daily Mail reported.
Lay began taking Wegovy in late 2023 after trying several diets without success. She remained on the medication for nine months, even though she felt something "wasn't right."
“My appetite reduced slightly at first,” Lay, a financial services worker, was quoted as saying. “But not enough to make a meaningful difference, so I increased the dosage each month.”
After seeing limited results with Wegovy, Lay stopped the medication for four weeks before switching to Mounjaro. She described the transition period as experiencing the "worst food noise" and said she gained more than seven pounds while waiting for the first drug to clear from her system.
Lay then spent six months on Mounjaro but said she was "barely eating" and still failed to achieve the weight loss she expected.
“I only lost seven pounds,” she said. “I realised the injections simply weren't effective for me and something had to change.”
Her doctor eventually advised her to stop taking the medication because they were concerned she was not eating enough, the report said.
Lay said the experience was “emotionally exhausting and honestly quite soul-destroying,” and "deeply disheartening.” Watching others succeed on the drugs made it even harder.
After discontinuing the injections, Lay adopted a very low-calorie diet with support from expert nutrition advisers who provided personalized guidance.
“Once the medication was fully out of my system, I began to feel genuinely better,” Lay said, adding that her “energy returned, digestion improved, and the constipation disappeared.”
Within a year, she went from a dress size 18 to size 12, the smallest she had been in 17 years, with her weight falling to 13 stone 5 pounds, the report said.
Clinical trials have shown that most people taking these medications experience substantial weight loss.
Around 2.5 million adults in the UK are estimated to be using weight-loss injections, while hundreds of thousands have signed up for the newly approved Wegovy pill, which was rolled out by the NHS this month.
But some people are 'non-responders', meaning they do not lose a meaningful amount of weight despite treatment. Research earlier this year found that around one in 10 people taking GLP-1 medications are considered non-responders.
Although GLP-1 receptor agonists have delivered remarkable results for many people, they do not work the same way for everyone. Obesity is a complex condition influenced by brain signaling, hormones, genetics, and metabolism, meaning treatment responses can vary significantly. Possible reasons include:

Oral Rehydration Solution (ORS) is one of the simplest yet most effective life-saving solutions that every household should keep readily available, doctors said on World ORS Day.
Observed every year on July 29, World ORS Day raises awareness about the importance of ORS—a scientifically formulated mix of glucose and electrolytes, including sodium and potassium—that helps prevent and treat dehydration caused by diarrhea, vomiting, fever, heat, and excessive sweating.
First introduced in 1969, ORS has transformed the treatment of dehydration worldwide. Since 2003, the World Health Organization (WHO) and UNICEF have recommended a low-osmolarity ORS formula, which improves fluid absorption and reduces the need for intravenous fluids. Today, ORS remains the gold standard for preventing and treating dehydration, particularly in children and people living in resource-limited settings.
Dr. Ranjana Bhatt, Associate Director - Internal Medicine, Paras Health, Panchkula, told HealthandMe that ORS is not a medicine that cures the underlying illness but is designed to prevent and correct dehydration.
Dehydration occurs when the body loses more water and electrolytes than it takes in, most commonly due to diarrhea or vomiting. It can develop rapidly, especially in young children, older adults, and people with chronic illnesses.
ORS works through a well-established biological process in the small intestine. It contains the right balance of glucose and sodium, which are absorbed together through special proteins called sodium-glucose cotransporters (SGLTs). As sodium enters the bloodstream, water follows, allowing the body to rehydrate efficiently.
This mechanism makes ORS more effective than plain water—and often more effective than many commercial sports drinks—for replacing lost fluids and electrolytes quickly and safely.
"Recognizing the early signs of dehydration, such as excessive thirst, dry mouth, dizziness, reduced urination, and unusual fatigue, and starting ORS promptly can prevent serious complications. On ORS Day, we encourage every family to make ORS a household essential and use it appropriately while seeking timely medical care whenever symptoms are severe or persistent," Dr. Bhatt said.
Dr. Amit Prakash Singh, Consultant - Internal Medicine, CK Birla Hospital, Delhi, told HealthandMe that ORS is one of the simplest, most affordable, and most effective ways to prevent dehydration.
"ORS is accessible for almost everyone, and the product is recommended by the World Health Organization to start treating dehydration caused by diarrhea at home. Having ORS packets at home enables treating dehydration without going to the doctor first and potentially avoiding hospitalization," he said.
Besides diarrhea, ORS can help replace fluids and electrolytes lost due to:
"ORS is not just for diarrhea. Whenever there is a lot of fluid loss or electrolyte loss, ORS can be used. ORS can be consumed for vomiting due to gastroenteritis, food poisoning, or viral infection (provided the person can sip small amounts repeatedly)," Dr. Singh said.
Doctors caution that ORS only replaces lost fluids and electrolytes—it does not treat the underlying disease.
It may help prevent dehydration after fever, vomiting, or excessive sweating, but it is not a treatment for abdominal pain, acidity, indigestion, constipation, gastritis, or irritable bowel syndrome (IBS). Persistent or severe symptoms should always be evaluated by a healthcare professional, Dr Singh said.

Liver disease is unusual among serious conditions in that it can progress significantly without producing symptoms that would prompt most people to seek medical attention. Hepatitis, which is inflammation of the liver, is the most common starting point for that progression.
It may be caused by viral infections including Hepatitis B and Hepatitis C, excessive alcohol consumption, fatty liver disease, certain medications, or autoimmune conditions. In many cases, the person carrying it feels entirely well while damage accumulates over months and years.
The liver does regenerate, but that capacity has limits. When inflammation persists, healthy liver cells are progressively replaced by scar tissue, a process called fibrosis.
Continued scarring eventually produces cirrhosis, where the liver loses its structural integrity and its ability to perform the functions the body depends on it for, such as processing toxins, producing proteins involved in blood clotting, regulating metabolism, and supporting digestion. At this stage, the damage is largely irreversible.
The timeline from hepatitis to cirrhosis typically spans years or even decades, which is precisely what makes delayed diagnosis so consequential. Each year of untreated inflammation is a year of accumulated scarring.
By the time cirrhosis produces obvious symptoms such as jaundice, abdominal swelling from fluid accumulation, internal bleeding from enlarged veins in the oesophagus, cognitive changes from toxin build-up, kidney involvement, the disease has already reached an advanced stage. Cirrhosis also carries a significantly elevated risk of liver cancer.
The clinical picture is meaningfully better when liver disease is identified early. Effective antiviral medications can control chronic Hepatitis B and cure most cases of Hepatitis C, substantially reducing the risk of progression.
Fatty liver disease, when caught before significant fibrosis has occurred, can often be reversed through weight management, blood sugar control, reduced alcohol intake, and consistent physical activity. These interventions are accessible, evidence-based changes that work when applied before the disease has advanced.
Screening is where early identification happens. Blood tests measuring liver enzymes and imaging studies can detect liver inflammation and early fibrosis well before symptoms appear.
For individuals with diabetes, obesity, a family history of liver disease, a history of blood transfusions, or other known risk factors, periodic liver assessment is a practical and important part of routine care rather than an optional precaution.
The pattern that gastroenterologists consistently encounter is patients presenting with advanced liver disease who had risk factors identifiable years earlier. Hepatitis B and C are both detectable through simple blood tests.
Fatty liver shows up clearly on ultrasound. The window for effective intervention exists, and it is considerably wider earlier in the disease than most people assume when they have never been tested.
This draws attention to a disease that carries a substantial global burden but remains widely undertreated because it does not announce itself. For anyone with known risk factors, or who has never had their liver function assessed, the appropriate response to that is a conversation with a physician, before symptoms, rather than after.
