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.

Four years after suffering from a rare neurological condition known as Stiff-Person Syndrome, Céline Dion, known for power ballads like My Heart Will Go On and Because You Loved Me, has announced her return to the stage.
The incurable condition had affected her singing voice and even her ability to walk.
In a message on her Instagram page, the singer announced plans to play a 10-night residency at the 40,000-capacity Paris La Défense Arena in September and October.
Calling her comeback "the best gift of my life", 58-year-old Dion said: "I'm doing great, managing my health, feeling good. I'm singing again, even doing a little bit of dancing.
"I'm so ready to do this. I'm feeling good, I'm strong, I'm feeling excited, obviously, [and] of course, a little nervous," she said, while thanking her fans for the “prayers and support, kindness and love”.
Stiff-Person Syndrome is a neurological disease caused by the signals from the nerves to the muscles not working properly. It affects an estimated 8,000 people worldwide.
It is also an autoimmune is a neurological disease caused by the signals from the nerves to the muscles not working properly. It affects an estimated 8,000 people worldwide.
It is also an autoimmune condition, that is linked to diseases such as type 1 diabetes, thyroiditis, vitiligo, and pernicious anemia.
For some, it can be debilitating. SPS is progressive, meaning it gets worse over time. There is no known cure.
Common symptoms may include:
The condition is also more common among women than men, and affects people between the ages of 20 and 60.
While there is no known cure for SPS, current treatments such as intravenous immunoglobulin (IVIg) can help manage the symptoms.
Dion announced her diagnosed with Stiff Person Syndrome (SPS) in December 2022 in an emotional Instagram video. The condition had affected "every aspect of my daily life", she told her fans.
The best-selling artists of all time began noticing her symptoms, such as feeling "a little spasm" while performing on stage. She found her “voice was struggling", BBC reported.

Even though she experimented with her singing to ease the stress on her vocal cords, her condition worsened. She also began facing difficulties while walking.
"It's like somebody is strangling you. It's like somebody is pushing your larynx [or] pharynx," she told NBC News.
Determined to get back on her feet and sing, worked "all my body and soul, from head to toe, with a medical team", French Vogue magazine reported.
"Five days a week, I undergo athletic, physical, and vocal therapy. I work on my toes, my knees, my calves, my fingers, my singing, my voice."
The intense workouts enabled her to make a comeback at the 2024 Paris Olympics, singing Edith Piaf's classic Hymne à l'Amour from the Eiffel Tower.

While a hickey is generally harmless, in several shocking incidents, it has led to strokes and even death.
A hickey is typically a dark red or dark purple mark on your skin caused by intense suction.
According to health experts, the strong suction from the passionate love bite leads to blood clots that travel to the brain. It then blocks a vital artery and causes a embolic stroke.
Embolic stroke is a type of ischemic stroke caused by a blood clot or debris (embolus) that forms elsewhere in the body—often the heart—and travels through the bloodstream to block a blood vessel in the brain.
The Independent reported the case of 17-year-old Julio Macias Gonzalez, who suffered convulsions while eating dinner with his family after hanging out with his 24-year-old girlfriend and later died.
In a similar case reported from New Zealand, a 44-year-old woman suffered a stroke following a hickey.
While non-fatal, the 2010 study published in the New Zealand Medical Journal reported the medical condition “a rare phenomenon.”
In yet another case, the Danish Medical Journal reported the incident of a 35-year-old woman who experienced a sudden onset of right-sided weakness due to a left middle cerebral artery stroke 12 hours after she had obtained a love bite on the left side of her neck.
“Generally speaking, hickeys are simply superficial bruising, and there’s no scientific evidence available that could inform our thinking about this situation as it relates to stroke,” Teresa Roncon, spokeswoman for the Heart and Stroke Foundation of Canada, was quoted as saying Global News.
While it's generally harmless, in some extreme cases, it can raise the risk of damaging the carotid or vertebral artery due to extreme pressure.
The carotid arteries, one on each side of the neck, are responsible for supplying blood to the head, including the brain. Vigorous manipulation of the neck, including the action of a hickey, can cause the inner wall of the carotid artery to rupture. (This process is medically termed as carotid artery dissection).
Such a dissection is a nidus, a place where bacteria can multiply, for the formation of a blood clot. The blood clot can then get dislodged and enter the brain circulation, eventually causing a stroke.
While there is nothing wrong with giving or receiving love bites, it is imperative to note that one should not dig their teeth too deeply into the other person's neck to avoid injury and damage to sensitive structures like the carotid artery or the jugular vein (a vein that carries deoxygenated blood from the skull to the body).
While there are practically no ways to cure a hickey, you can speed up the healing process. These processes can help you expedite the process:

Ten-year-old Myla from the UK's North Yorkshire, with severe eye strain, was diagnosed with a severe brain tumor that led to her death.
The young girl had been suffering from headaches and dizziness, which were dismissed as mere eye strain due to playing on her iPad too much.
Thinking that she needed eyeglasses, her parents took her for an eye appointment, where she was diagnosed with an aggressive diffuse midline glioma — a type of brain tumor.
Myla was diagnosed with a 7-10cm tumor and was rushed to Sheffield Children's Hospital for an operation to remove 60 per cent of the mass. The youngster underwent a grueling 30 rounds of radiotherapy but tragically passed away on January 15, The Mirror.co.uk reported.
Healthandme spoke to health experts to understand the role of eye strain and brain tumors.
The health experts noted that although prolonged exposure to digital screens can raise the risk of vision problems, they cannot cause brain tumors.
"Eye strain is most commonly linked to prolonged screen use, poor ergonomics, or uncorrected vision, and in the vast majority of cases, it is not a sign of brain cancer," Dr. Parul Maheshwari Sharma, Ophthalmologist and Principal Director & HOD - at Fortis Gurugram, told HealthandMe.
"The likelihood of experiencing eye strain being an indication of brain cancer is minimal," added Dr. Mahipal Singh Sachdev, Chairman & Medical Director, Centre For Sight Group of Eye Hospitals.
The doctors explained that brain tumors are rarely present as simple eye strain; they are usually associated with additional symptoms such as:
Eye strain, also referred to as digital eye strain or computer vision syndrome, is caused by staring at screens for extended periods of time and decreased blinking.
It generally occurs due to benign factors such as excessive screen time, dry eye, or uncorrected vision.
While prolonged screen use can cause discomfort, dry eyes, and temporary blurred vision, it does not lead to the development of cancer.
"There is no evidence to suggest that screen-induced eye strain can cause brain tumors," Dr Sharma said.
"Although there may be visual changes due to a tumor that involves the optic nerve or hypothalamus, simple eye strain is not indicative of brain tumors and would not be considered an early warning of a brain tumor. There is an extremely low probability that eye strain will be due to a brain tumor," Dr. Sachdev told HealthandMe.
However, the experts agreed that long screen time can lead to severe eye strain.
Brain tumors are generally attributed to genetics, exposure to radiation, or other unknown factors.
Numerous types of red flags could indicate the presence of a serious neurological disorder. Some examples include
Higher-risk patients include:
To help combat eye fatigue, individuals can adopt some simple habits, such as
