Stress is an unavoidable part of life, and while it often carries a negative connotation, it is actually a fundamental survival mechanism. When faced with a perceived threat, whether physical or emotional, the body instinctively reacts to protect itself. This automatic response is commonly known as the "fight, flight, or freeze" response. While it serves an essential function in dangerous situations, chronic activation of this response due to daily stressors can have significant consequences for mental and physical health.
The body’s response to stress is rooted in human evolution. When our ancestors encountered a predator, their nervous systems immediately prepared them to either confront the threat (fight), escape to safety (flight), or become still and unnoticed (freeze). While modern-day stressors may not include wild animals, our nervous system reacts similarly to job pressures, financial worries, or social conflicts.
According to the Cleveland Clinic, stress is the body's response to change, activating a physiological reaction that helps us adapt and protect ourselves. While short-term stress can be beneficial, prolonged exposure can lead to an overactive stress response, negatively impacting overall well-being.
The fight response prepares the body for direct action. When triggered, the nervous system releases adrenaline, increasing heart rate, blood pressure, and muscle tension. While this reaction once helped early humans fend off predators, today it manifests as irritability, frustration, or aggression.
For instance, the employee who has experienced too much workload may work extremely long hours just to succeed. In short term, the action may produce good results but mostly ends in burnout, anxiety, and physical illness, for example, tension headache or digestion problems.
The flight response triggers an intense need to remove oneself from a stressful situation. Just as our ancestors would flee from danger, modern individuals may avoid conflict, quit jobs impulsively, or detach from relationships when overwhelmed.
Flight mode is linked with restlessness and anxiety. Individuals may have a sense of needing to get up and go-pacing, changing environments constantly, or avoiding tasks that seem too overwhelming. Someone with a flight response might have the desire to change jobs constantly, relocate constantly, or become reclusive in order to avoid perceived dangers.
The freeze response occurs when the nervous system perceives a threat as too overwhelming to fight or flee. Rather than taking action, individuals shut down, feeling numb, disconnected, or paralyzed by fear.
Unlike fight or flight, which involve heightened activation, freeze mode slows down physiological functions. A person experiencing freeze mode may feel physically unable to move, struggle to make decisions, or find themselves dissociating from their emotions. This can manifest in situations such as public speaking anxiety, where someone might "blank out" or feel stuck in the moment.
When faced with a stressor, the autonomic nervous system (ANS) activates, triggering physiological changes, including:
For those experiencing the freeze response, the body undergoes a different reaction, often reducing heart rate and causing physical immobility rather than heightened activation.
While the stress response is necessary for survival, frequent activation due to daily stressors can take a toll on health. Recognizing your default response—whether fight, flight, or freeze—can help in developing effective coping mechanisms.
If possible, changing your environment can help signal to your brain that the threat has passed. Stepping outside for fresh air, finding a quiet place, or distancing yourself from overwhelming stimuli can help regulate emotions.
Deep, slow breathing can be used to counteract the stress response by engaging the parasympathetic nervous system, which promotes relaxation. Techniques such as diaphragmatic breathing or the 4-7-8 method (inhale for four seconds, hold for seven, exhale for eight) can be particularly effective in calming the body.
This helps release pent-up energy and aids in the endorphin cascade, natural boosters for our mood.
Relieving oneself from stress can come in many ways, but sharing it with trusted friends, a family member, or a good therapist will sure give that psychological boost of hope. Social support is an especially effective way of cushioning people against the stressors that they are subjected to in chronic forms.
While occasional stress is normal, chronic activation of the fight, flight, or freeze response can indicate underlying mental health concerns, such as anxiety disorders or post-traumatic stress disorder (PTSD). If stress is affecting daily life—leading to sleep disturbances, difficulty concentrating, or persistent feelings of fear—it may be time to consult a mental health professional.

India is better prepared to deal with potential Hantavirus outbreaks due to the healthcare infrastructure and quarantine systems established during the COVID-19 pandemic, according to Dr NK Ganguly, former Director General of the Indian Council of Medical Research (ICMR).
In an exclusive interview with HealthandMe, Dr Ganguly said that while isolated cases of Hantavirus have appeared in India in the past, especially in crowded peri-urban and urban settings in Kerala, large-scale outbreaks have largely been reported in countries such as China, Argentina, the UK, and the US.
Dr Ganguly said that India's healthcare system significantly improved after the deadly COVID pandemic.
“India is overprepared in a way that during the COVID-19, our system, even at the district level or in much more rural settings, got established,” he said.
He pointed out that hospitals now have access to ECMO, BPAP systems, ventilators, and oxygen management facilities to curb the spread in case of an outbreak.
Dr Ganguly also mentioned the availability of antiviral drugs and experimental vaccine efforts that could potentially be explored for hantavirus treatment. “There are some crude vaccines which are made here also,” he said.
He added that India’s quarantine systems and public health drills developed during COVID-19 would also help contain future outbreaks.
“I think India will be okay because of the sheer transmission dynamics of this virus,” he said.
Hantavirus is a zoonotic disease that primarily gets transmitted through contact with infected rodents or exposure to their urine, droppings, and saliva, though rare cases of person-to-person transmission have also been reported.
According to the World Health Organization (WHO), 11 cases — including three deaths — have been confirmed so far. However, additional suspected and confirmed cases are likely to emerge across countries.

The One Health approach is critical in understanding and containing outbreaks like hantavirus, Dr Ganguly said.
The One Health approach, which integrates human health, animal health, and environmental monitoring, is also crucial to target the emerging infectious diseases, he noted.
Further, the noted microbiologist stressed the importance of strengthening surveillance across humans, animals, and the environment.
He explained that disease surveillance requires collaboration between bird specialists, forest experts, environmental scientists, and mammologists, especially for tracking zoonotic infections such as avian flu and hantavirus.
“In avian flu, birds follow special migration routes, so we needed bird specialists, forest experts, environmental experts, and mammologists,” Dr Ganguly said.
The expert also highlighted the growing challenge posed by shrinking spaces between humans and animals and the role of antimicrobial resistance (AMR) in emerging disease threats.
“Animal health is equally important. We need to maintain them, track their movements, and do surveillance,” he said.
Dr Ganguly also warned that rising temperatures and shrinking boundaries between humans and animals could increase the risk of future infections.
“It is an environmental infection. With the rise of temperature, more hantavirus infections occur,” he told HealthandMe.
Calling surveillance one of the most critical tools in outbreak prevention, he urged India to strengthen monitoring systems for animals, vectors, and humans alike.
“We need to set up a dedicated surveillance for hantavirus in India, and we need to track hantavirus,” he said.
Dr Ganguly explained that to date, hantavirus cases in India have been detected accidentally during testing for respiratory infections or flu-like illnesses using advanced panel-based diagnostic systems.
“Like now these days, what happens is that when you are getting respiratory infection or flu-like symptoms, they put up a test system which is known as bio-fire or a thing like that which identifies 26 panels and gives the CT scoring of that, so from there, hantavirus emerged,” he said.
He added that India should strengthen surveillance tools and continue monitoring infections in animals, vectors, and humans alike.

Prateek Yadav (38), the son of late Samajwadi Party founder Mulayam Singh Yadav, died due to a massive blockage in the blood vessels of the lungs, leading to a collapse of the heart and respiratory system, as revealed in the postmortem examination report.
According to the autopsy findings, the provisional cause of death was recorded as “cardiorespiratory collapse due to massive pulmonary thromboembolism.” In simple terms, doctors said a large blood clot had blocked blood flow to the lungs, causing his heart and breathing to fail.
An embolism is any object (clot, fat, air, tissue) traveling through the bloodstream that becomes stuck, blocking blood flow. A thromboembolism is a specific type of embolism where that travelling object is a piece of a blood clot (thrombus) that has broken off from its original site.
It is a life-threatening condition that happens when a blood vessel in the lungs is blocked by a blood clot.
The common symptoms may include:
The blood clot starts in a deep vein in the leg and travels to the lung in most cases. Rarely, the clot forms in a vein in another part of the body, noted Mayo Clinic. When a blood clot forms in one or more of the deep veins in the body, it is called a deep vein thrombosis or DVT.
Other symptoms of pulmonary embolism include:

Meanwhile, Karnataka's Planning and Statistics Minister, D. Sudhakar (66), passed away after a prolonged battle with a lung infection.
The most common lung infections that people experience are pneumonia, bronchitis, tuberculosis, influenza-related infections, and severe viral illnesses.
Experts noted that these lung infections cause fluid or pus to fill the air sacs, which prevents oxygen from entering the bloodstream.
"What may initially appear as a routine cough, fever, or chest infection can progress to severe pneumonia, respiratory failure, sepsis, or permanent lung damage,” Dr. Vikas Mittal, Director - Pulmonologist, CK Birla Hospital, Delhi, told HealthandMe.
Warning signs include
Dr. Nikhil Rajvanshi, Consultant - Paediatric Pulmonology, Rainbow Hospital, Delhi, told HealthandMe that children may be more at risk of pulmonary infections as they can become dangerous quickly because their lungs and immune systems are still developing.
Common illnesses such as bronchiolitis, pneumonia, influenza, and other viral infections may rapidly lead to breathing difficulty, low oxygen levels, dehydration, and respiratory distress. Infants, premature babies, malnourished children, and those with asthma or congenital disorders are at higher risk of complications.

US President Donald Trump's attempt to clarify the meaning of "sea" while discussing drug smuggling has again raised concerns of dementia.
While the 79-year-old President rambled between “sea and see” in the middle of discussing drug problems in the US, social media went rife with the rumor of his cognitive decline.
"Drugs coming by sea meaning coming by water. A lot of people don’t know what I mean by sea. They think I mean vision. I’m talking about sea like the sea," he said. He was speaking at the White House, while hosting law enforcement officials for a dinner in the Rose Garden in celebration of National Police Week.
His comments were called out by social media as his apparently worsening cognitive capabilities.
"When he says 'a lot of people' he means 'me.' His cognitive issues are a crisis," one social media user declared, while another admitted, "He’s getting worse."
Trump has spoken on sea and see, during a maternal healthcare event last week, where he also referred to himself as the “father of fertility.”
Earlier, speaking at the White House Small Business Summit, Trump said he has taken the Montreal Cognitive Assessment three times and “aced each one,” claiming a doctor told him it was the first time they had seen a perfect score, The Daily Beast reported.
The US President said he answered the test questions easily, suggesting he is cognitively in good condition—a claim that critics have repeatedly questioned.
“The first question is very easy,” he said. “You have a lion, a bear, an alligator, and a—what’s another good…? A squirrel. Which is the squirrel?” He added that the difficulty increases as the test progresses. “By the time you get to the middle, they’re very tough.”
However, the test’s creator, Canadian neurologist Ziad Nasreddine, has challenged Trump’s claims. “It wasn’t designed to be a test of IQ,” he told nine.com.au. “It was designed to assess normal cognitive performance.”

A group of medical experts, including neurologists, psychiatrists, and other physicians, has sounded the alarm over what they’ve described as Trump’s deteriorating mental health.
The experts have not specifically examined Trump face-to-face. But, they analyzed Trump's statements and behaviors over the past year, and stated that he’s “mentally unfit” and must be removed from office “with the greatest urgency” amid the escalating tension around the world, according to their statement published in The BMJ.
“It is our professional opinion that they (Trump's statements) reflect a rapidly worsening, reality-untethered, increasingly dangerous decline,” the experts said.
They also listed some of Trump’s observable serious medical issues, such as “Marked deterioration in cognitive functioning, evidenced by disorganized and tangential speech, rambling digressions, factual confusions, unexplained sudden changes of course in strategic matters, both national and international, episodes of apparent somnolence during critical public proceedings.”

What The White House Says
The White House has continued to say that Trump remains in strong health.
In October 2025, White House physician Captain Sean Barbabella said the president “continues to demonstrate excellent overall health,” AOl.com reported.
"President Trump’s sharpness, unmatched energy, and historic accessibility stand in stark contrast to what we saw during the last administration when Democrats and other lunatics intentionally covered up Joe Biden’s serious mental and physical decline from the American people,” White House spokesman Davis Ingle was quoted as saying to The Daily Beast.
