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.

The NHS has issued an alert for anyone taking a widely used heart medication. People are being advised to watch for serious warning signs, including yellowing of the skin or “nosebleeds lasting more than 10 minutes.”
Propranolol is a beta blocker that slows the heart rate and relaxes blood vessels, helping lower blood pressure and reduce the heart’s oxygen demand. It is also prescribed to ease symptoms of anxiety, such as trembling or excessive sweating, and can help prevent migraines. The medication is prescription-only but is commonly prescribed throughout the UK.
According to the Mirror, the British Heart Foundation reports that more than 50 million beta blocker prescriptions are issued in the UK each year, including for propranolol. Patients usually take it once a day, in either a standard or slow-release form.
While propranolol is generally safe, it does carry possible side effects. The NHS advises contacting 111 immediately if serious symptoms affecting the blood or kidneys appear.
The NHS notes: “Like all medicines, propranolol can cause side effects in some people, but many experience none or only minor effects. Side effects often ease as your body adjusts to the medication.”
Common side effects include headaches, fatigue, weakness, cold fingers or toes, nausea, and stomach discomfort. While most people over 12 can safely take propranolol, the NHS recommends consulting a doctor first if you have a history of low blood pressure, heart failure, depression, or diabetes.
More serious reactions can occur, including yellowing of the eyes or skin, pale stools, or dark urine. The NHS also warns of nosebleeds lasting longer than 10 minutes, unexplained bruising, or increased tendency to bruise easily.
Anyone experiencing these warning signs should contact a doctor or call 111 immediately. The NHS also cautions against stopping propranolol abruptly without medical guidance, as this could trigger severe heart problems, including chest pain or even a heart attack.
While propranolol is widely prescribed and generally safe for most adults, certain people need to monitor themselves more closely or consult their doctor before use. Those with low blood pressure, heart failure, slow heart rates, diabetes, respiratory conditions like asthma, or a history of depression may face higher risks of side effects. Pregnant or breastfeeding women should also speak to a healthcare professional before taking the medication.
The NHS emphasizes that even minor symptoms—like unusual fatigue, dizziness, or cold hands and feet—should not be ignored, especially if they worsen over time. Monitoring for these effects early can prevent more serious complications.

A California man died last weekend after eating so-called death cap mushrooms, marking the third fatality linked to the toxic fungi in the state since November.
Health officials say California is seeing an unusually high number of mushroom poisonings this season. Between November 18 and January 4, at least 35 cases were reported statewide. In a typical year, the number is usually fewer than five.
“This year’s figures are far beyond what we normally see,” said Sheri Cardo, a communications specialist with the California Department of Public Health.
At least three people have now lost their lives in California due to death cap mushroom poisoning since November. Media reports indicate a sharp rise in cases tied to foraged wild mushrooms, with more than 35 poisonings recorded over the past three months.
“The numbers we’re dealing with this year are comparatively off the charts,” Cardo told NBC News.
The most recent death occurred in Sonoma County and was the first fatal wild mushroom poisoning reported there this season, according to county health officials.
Dr. Michael Stacey, interim health officer for Sonoma County, urged residents to avoid eating wild mushrooms unless they are purchased from reliable grocery stores or licensed sellers. He warned that death cap mushrooms can look strikingly similar to safe, edible varieties.
Death cap mushrooms, scientifically known as Amanita phalloides, are among the most poisonous mushrooms in the world. They commonly grow beneath oak trees and can be found in parks, gardens, and wooded areas.
Experts say these mushrooms are often mistaken for edible types because of their appearance. Typical features include:
Symptoms usually begin between six and 24 hours after ingestion. Early signs often include stomach pain, nausea, vomiting, and diarrhoea.
In many cases, symptoms ease or disappear after one or two days, which can create a false sense of recovery. By that point, however, the toxins may have already caused severe damage to the liver.
According to experts, the poison responsible, known as amatoxin, can seriously harm the liver, kidneys, and digestive system. Without prompt treatment, the damage can be fatal.
U.S. Poison Centers receive an average of about 52 calls each year related to amatoxin exposure, said Hallen-Adams, though not every case is officially reported.
The danger may now be starting to decline in parts of California. Mike McCurdy, president of the Mycological Society of San Francisco, said he has noticed far fewer death cap mushrooms during recent foraging trips.
Earlier this winter, McCurdy said he spotted hundreds of death caps during a two- to three-hour walk in Sonoma County. On a recent outing near Lafayette, California, he found just one. “I think we’re getting close to the end,” he said.

Nearly four years ago, Teresa Sanchez was in Mexico for a medical procedure when her right eye began to feel unusually dry and irritated. At first, it seemed minor. She assumed her contact lens might be torn or that the switch from daily lenses to monthly ones was causing dryness. She even wondered if her body was fighting off an infection, as per CNN.
What she did not realize at the time was that a microscopic organism was slowly attacking her cornea. Over the next three months, the parasite caused irreversible damage to her vision and triggered searing pain that spread across her head.
“I couldn’t even keep the blinds open in my room,” said Sanchez, now 33 and living in Las Vegas. “Light would cause unbearable pain. That’s when I knew something was seriously wrong.”
By then, she had already seen multiple optometrists and had been misdiagnosed. Frustrated and desperate for answers, Sanchez began researching her symptoms on her own.
Online searches led Sanchez to a condition she had never heard of: acanthamoeba keratitis. An eye specialist later confirmed it. Keratitis refers to inflammation of the cornea, the clear, dome-shaped layer at the front of the eye that plays a central role in focusing vision. Acanthamoeba is a microscopic, single-celled organism that cannot be seen without a microscope.
According to Dr. Jacob Lorenzo-Morales, a professor of parasitology at the University of La Laguna in Spain, acanthamoeba is commonly found in soil and water. It does not require a host to survive, which makes it especially resilient.
Once the organism comes into contact with the eye, it can attach itself to the cornea. Dr. Paul Barney, an optometric physician and director at the Pacific Cataract and Laser Institute in Alaska, explained that even tiny breaks in the corneal surface can allow the parasite to burrow deeper into the eye.
Acanthamoeba keratitis is considered rare. Based on data from 20 countries, including the UK, India, the US, Canada and Brazil, there are more than 23,000 cases worldwide each year. Yet a striking pattern stands out. Between 85% and 95% of people who develop the infection wear contact lenses.
Contact lenses can cause microscopic abrasions on the cornea, creating an entry point for the parasite. The organism can also cling to the lens itself or become trapped between the lens and the eye, making it easier to penetrate the corneal tissue.
“If it’s not diagnosed early and treated aggressively, the outcome can be devastating,” Barney said. “The parasite feeds on the cornea, triggering inflammation and tissue damage that can lead to permanent vision loss.”
In some cases, vision can be partially restored with treatment. Others require a corneal transplant.
Treating acanthamoeba keratitis is especially difficult because the organism has strong defense mechanisms. It can sense threats and respond by forming a cyst, allowing it to lie dormant for months or even years.
This resilience means treatment often stretches over long periods and involves intense discomfort. Because the eye is extremely sensitive, patients must work closely with specialists and strictly follow treatment instructions.
Early diagnosis is one of the biggest challenges Because acanthamoeba keratitis is uncommon, many optometrists may not recognize it right away. As a result, many contact lens users only learn about the condition after they develop it or come across viral videos discussing it online.
Many patients have expressed surprise that they were never clearly warned about the risks of wearing contacts while showering or swimming.
The Contact Lens Society of America emphasized that contact lenses are medical devices and require strict hygiene. This includes avoiding water exposure during swimming, showering or sleeping. The organization also stressed the importance of patients asking questions and carefully reviewing care instructions.
In addition to severe pain and light sensitivity, acanthamoeba keratitis can cause redness, blurred vision, dryness, excessive tearing and the sensation that something is stuck in the eye.
Because these symptoms overlap with other conditions, misdiagnosis is common. Barney said the infection is frequently mistaken for herpes simplex keratitis, a major cause of infection-related blindness. In its earliest stages, it can even resemble pink eye.
That was the case for Sanchez. Her first optometrist diagnosed pink eye. The prescribed drops blurred her vision. A second optometrist suspected a bacterial infection, and while antibiotic drops offered brief relief, she soon lost vision in the affected eye.
Experts stress that contact lens hygiene is critical. Always clean and store lenses using approved contact lens solution, never water. The solution in your lens case should be replaced daily. Wash and dry your hands thoroughly before handling lenses.
Sleeping in contact lenses should be avoided, as it increases dryness, irritation and the risk of corneal damage. Daily disposable lenses may lower infection risk compared to monthly lenses.
For water-based activities, glasses or prescription goggles are safer options. Some people may also consider vision correction surgery after discussing risks and suitability with a doctor.
