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.

In a major push towards eliminating cervical cancer from India, Prime Minister Narendra Modi today launched the nationwide Human Papillomavirus (HPV) vaccination program for girls aged 14 years.
The new vaccination drive comes as cervical cancer remains the second most common cancer among women in India, with nearly 80,000 new cases and over 42,000 deaths reported annually. As per data from the ICMR-National Cancer Registry Program (NCRP), an estimated 78,499 new cases and 42,392 deaths were reported in 2024.
Calling it a "decisive step”, the government noted that it is aimed at “strengthening the vision of ‘swasth nari’ (healthy women) while being rooted in scientific evidence, strict regulatory oversight and global best practices”.
“India's vaccination drive reflects safety, responsibility, and long-term commitment to women’s health,” it added.
The national program will use Gardasil, a quadrivalent HPV vaccine that protects against HPV types 16 and 18, which cause cervical cancer, as well as types 6 and 11.
However, social media has been rife with concerns around the safety of the vaccine, its impact on women’s reproductive health, among others.
Fact: The HPV vaccines come with a “confirmed strong safety record”.
“Extensive global monitoring shows a strong safety profile supported by scientific reviews. Independent evaluations have found no causal link between vaccination and chronic harm, strengthening confidence in its continued use worldwide,” the government said.
The vaccine has been licensed in India since 2008, and the new rollout follows recommendations by the World Health Organization (WHO) and approvals from the National Technical Advisory Group on Immunization (NTAGI).
“HPV vaccines have been given to hundreds of millions globally. Extensive post-marketing surveillance shows an excellent safety profile, with no causal link to serious adverse outcomes. The evidence is robust, transparent, and reassuring,” Dr. CS Pramesh, Director of the Tata Memorial Hospital, Mumbai, shared in a post on the social media platform X.
Fact: The vaccine has been in use in India. It has been administered for years since 2008 with successful implementation in states like Punjab, Sikkim, and Tamil Nadu.
Fact: The HPV vaccine has been proven to prevent cervical cancer
Studies show a 65 percent drop in cervical cancer cases among US women between 2012 and 2019 and an 88-89 percent reduction in precancerous lesions among Scottish women over a decade.
Countries with early HPV vaccine adoption have also shown large declines in HPV infection, high-grade cervical lesions, and cervical cancer incidence.
"Even when considering the rarest side effects, HPV vaccines are overwhelmingly safe. The protection they offer against cervical cancer far outweighs the minimal risks. Parents are encouraged to vaccinate their daughters on time," said Dr. Neena Malhotra, Professor and Head of Department, Department of Obstetrics and Gynecology, AIIMS New Delhi on X.
Fact: A single dose of the quadrivalent HPV vaccine is effective. It provides strong protection against HPV infection. It helps prevent cervical cancer.
“Strong global and Indian scientific evidence confirms that a single dose provides robust and durable protection when administered to girls in the recommended age group," the government said.

For all major diseases, early detection is key to improving treatment outcomes. However, when it comes to rare diseases, it is unpredictable, making it more challenging to diagnose. In such a scenario, Artificial Intelligence (AI) is playing a major role -- from early diagnosis to treatment, said health experts on Rare Disease Day.
Rare Disease Day is annually observed on February 28 to raise awareness about the lesser-known conditions and the underlying challenges for people suffering from them.
While many of the rare disorders are genetic, they often also surface without any prior family history. In some cases, they are diagnosed in infancy, while in others the manifestation is years late.
The advanced AI technology is, however, now enabling clinicians to better understand the patients’ genetic profiles and patterns that were not clearer earlier. The technology is also paving the way for earlier and more accurate diagnoses, bringing hope to thousands of patients worldwide.
“AI is revolutionizing the fight against rare diseases by speeding up diagnosis, research, and development of treatments. Rare diseases often take years to diagnose because of the lack of data, overlapping symptoms, and unclear diagnosis,” Dr. Vinit Banga, Director, Neurology, Fortis Escorts Hospital, Faridabad, told HealthandMe.
“AI algorithms can process medical records, genetic information, and images to identify patterns that may escape human detection, allowing for earlier and more accurate diagnoses,” he added.
In a February paper published in the journal Nature, researchers from the Shanghai Jiao Tong University in China presented an AI system called DeepRare -- a multi-agent system for rare disease differential diagnosis decision support, powered by large language models, integrating more than 40 specialized tools.
Using the specialized tools and knowledge sources, the agentic AI system generates ranked diagnostic hypotheses for rare diseases. Each of the tools was also accompanied by reasoning that links the conclusions to verifiable medical evidence.
Similarly, Harvard University-based researchers in a paper also published in the Nature journal in 2025 described an AI tool called PopEVE, which can identify genetic variants most likely to cause severe disease or death.
The model was able to identify more than 100 novel alterations responsible for undiagnosed, rare genetic diseases.
"AI is cutting short the diagnostic odyssey from years to weeks. Large-scale genomic projects help create a vital reference architecture for India and the global community,” Dr. Sudheendra Rao N R, MBBS, PhD, Scientific Advisor, Organization for Rare Diseases India, told HealthandMe.
By integrating deep phenotyping with AI, clinicians can decipher unknown genetic variants and accelerate the development of both repurposed and next-generation precision-therapies, the expert added.
AI can also help researchers identify new drug targets for the treatment of rare conditions.
Dr. Banga said that AI is also instrumental in accelerating drug development by processing enormous amounts of biomedical data to discover new targets for drugs and repurpose existing ones. Importantly, AI is cutting down on time and expenses.
“Machine learning algorithms enable the prediction of patient responses to particular treatments, making it possible to develop personalized treatment strategies,” the expert said.
Further, AI-enabled infrastructure is helping to achieve geographic neutrality, delivering the same caliber of healthcare screening to rural villages and Tier-3 cities as to Tier-1 hubs, ensuring a high-quality healthcare gateway that is no longer defined by where the patient lives.
Moreover, AI-based platforms bring together researchers from across the globe, making it easier to share data.
The World Health Organization (WHO) defines a rare disease as an often debilitating, chronic, or degenerative condition affecting 1 or fewer per 1,000 population.
Rare diseases do not have epidemiological data, are at high risk of misdiagnosis, and often also lack effective treatments.
According to the WHO ICD-11 (International Classification of Diseases), there are over 5,500 rare diseases. It also assigns unique identifiers (URIs) to them for better tracking.
There are estimated to be over 7,000 distinct rare diseases affecting more than 300 million people globally.

Do you know that congenital hypothyroidism, a rare disability, affects about 1 in 2,500–3,000 newborns globally, but in India, the incidence is higher -- approximately 1 in 1,000 births.
India records nearly 26 million births annually, with an estimated 10,000 babies born each year with Congenital Hypothyroidism.
This means 27 babies are born every day in India, with the condition that more than one is born every hour. Early treatment within the first 2 weeks of life can ensure normal brain development, while delayed treatment can reduce IQ by 30–50 points.
Congenital Hypothyroidism (CH) is a condition present at birth in which a baby’s thyroid gland does not produce enough thyroid hormone.
The thyroid is a small gland located in the neck. It produces a hormone called thyroxine (T4), which is essential for brain development, growth, and overall body metabolism. The thyroid hormone is especially important in the first few weeks of life.
The thyroid hormone helps in:
If a baby does not receive enough thyroid hormones soon after birth, it can lead to permanent intellectual disability and growth problems.
The good news is that congenital hypothyroidism is easily detectable and completely treatable if identified early.
What Causes Congenital Hypothyroidism? What Are The Symptoms?
Congenital Hypothyroidism may occur because:
One of the biggest challenges with Congenital Hypothyroidism is that most babies look completely normal at birth.
However, over time, some signs may appear:
How Is Congenital Hypothyroidism Detected?
1. Newborn Screening Test (Heel-Prick Test)
2. Confirmatory Blood Tests
If the screening test is abnormal, the doctor will order:
3. Thyroid Scan
In some cases, imaging tests are needed. The ultrasound of the neck (less accurate) and Nuclear Medicine Thyroid scan (more accurate) may be done to check whether the gland is absent, small, or misplaced. However, treatment should not be delayed while waiting for imaging.
When Should Treatment Start?
Treatment should begin as early as possible -- ideally within the first 14 days of life. Starting treatment within the first two weeks allows normal brain development.
Delaying treatment increases the risk of permanent intellectual disability.
Doctors will monitor:
Initially, blood tests are done every 2–4 weeks, then less frequently as the child grows. Proper follow-up ensures the dose remains correct. Some babies may need treatment for life.
In certain cases, doctors may reassess thyroid function after 3 years of age to see whether the condition is temporary or permanent. Most children who receive early and proper treatment grow up with completely normal intelligence and physical development.
Can Congenital Hypothyroidism Be Prevented? Why Early Screening Is So Important
Most cases cannot be prevented. However:
A baby with Congenital Hypothyroidism may look perfectly healthy. Without screening, diagnosis may be delayed until symptoms appear—by then, brain development may already be affected.
With early testing the diagnosis is simple; treatment is affordable; and outcome is excellent. But without testing:
Congenital Hypothyroidism is one of the most preventable causes of intellectual disability in children. A small heel-prick test in the first few days of life can protect your baby’s brain forever.
If you are expecting a baby or have a newborn, speak to your doctor about newborn thyroid screening.
Early diagnosis. Simple treatment. Normal life.
