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.

Once widely known as non-alcoholic fatty liver disease (NAFLD), the common and dangerous fatty liver condition was rephrased as Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) due to its strong link to metabolic health issues like obesity and diabetes.
MASLD now includes patients with fatty liver disease linked to metabolic risk factors such as obesity, diabetes, and hypertension.
Globally, it was observed that all patients who have non-alcoholic fatty liver disease also have some associated form of metabolic dysfunction. The patients reported having either obesity, diabetes, metabolic syndrome, hypertension, or cholesterol problems.
And all these problems eventually lead to significant comorbidities later, like some people developed heart disease, while others developed complications of diabetes.
In view of these, a global consensus process in 2023 involving hundreds of experts from different countries adopted MASLD as it better reflected these underlying causes of the condition.

MASLD is an umbrella term for liver conditions that develop in the presence of 1 or more cardiometabolic risk factors—including high blood sugar, elevated body mass index (BMI), and hypertension—but in the absence of other causes of liver fat accumulation.
The condition can be defined by excess liver fat accumulation (more than 5 per cent of liver weight) in the presence of metabolic dysfunction, independent of alcohol intake.
It encompasses a spectrum from simple steatosis to steatohepatitis, fibrosis, cirrhosis, and hepatocellular carcinoma.
“Initially, it was thought that having fatty liver disease without alcohol was a benign condition, but now it is recognized that, since it is associated with lots of metabolic comorbidities, it's no longer benign,” Dr. Ashish Kumar, Professor of gastroenterology and hepatology at Sir Ganga Ram Hospital in New Delhi, told HealthandMe.
He stated that whenever a diagnosis of fatty liver is present, "we should actually include other comorbidities, like obesity, dyslipidemia, which means cholesterol problem, diabetes, sugar problem, pre-diabetes, and hypertension. At least 50–70–80 percent of these patients will have one or more of these comorbidities".
Although alcohol has remained the number one risk for liver disease, MASLD seems to be rising globally, including among people who do not drink. Why?
The reasons include:
a sedentary lifestyle,
increased consumption of fast and processed food,
lack of exercise,
lack of sleep,
stressful life.

The experts noted that food, especially the increasingly accessible junk food or processed food, is a major culprit.
“So even if the person is not drinking alcohol, people are developing addiction to processed food, and this is causing an epidemic level of obesity and diabetes. Consequently, MASLD is also increasing, and now it is becoming the number one cause of liver disease,” Dr Kumar said.
According to Dr. Sanjay Goja, Director, Liver Transplant & HPB Surgery, Narayana Hospital, Gurugram, prevention must focus on following a healthy lifestyle like maintaining a healthy BMI, engaging in regular physical activity, and eating a balanced diet.
Controlling diabetes, cholesterol, and blood pressure is also important to prevent the risk of MASLD.
Dr Siddharth Badola, Manipal Hospital, Ghaziabad, suggested sustainable lifestyle changes such as:
Maintaining an adequate body weight: Even slight weight loss (5–10 percent) has been shown to significantly reduce liver fat and inflammation.
Follow a balanced and nutrient-rich diet: People should focus on consuming whole grains, fresh fruits and vegetables, lean proteins, and healthy fats, while limiting refined carbohydrates and processed foods.
Avoid foods with added sugar: Excess consumption of fructose, commonly found in packaged foods and sugary beverages, is a key contributor to fat accumulation in the liver.
Engage in regular physical activity: At least 150 minutes of moderate-intensity exercise per week is recommended to improve insulin sensitivity and liver health.
Manage associated metabolic conditions: Effective control of diabetes, hypertension, and dyslipidemia is essential in reducing the risk of MASLD progression.
Ensure adequate sleep and stress management: Poor sleep quality and chronic stress can negatively impact metabolic balance and liver function.
Keep your body hydrated with ample water intake and follow structured meal timings.
Heart attacks are now affecting younger people. (Photo credit: iStock)
Although a heart attack is generally considered a disease of the elderly, its incidence in young individuals is unfortunately on the rise. The reasons behind this are multifactorial. A heart attack is a condition where one of the arteries (blood vessels) suddenly becomes partially or completely occluded by a thrombus. Although the thrombus generally occurs suddenly, the underlying reason is a chronic process of lipid deposition in the vessel walls called atherosclerosis. Atherosclerosis can begin even in the first decade of life, but events like heart attacks conventionally occurred beyond 45 years in men and 55 years in women. On average, heart attacks occur in Indians about 10 years earlier than in their Western counterparts.
Dr Shyam Sasidharan, Consultant, Department of Cardiology, KIMSHEALTH Thiruvananthapuram, spoke about the early onset of heart attacks. From a population perspective, the rising number of heart diseases due to coronary artery disease (CAD) is significant not only because of its overall negative impact on the healthy population but also due to the potential for preventive interventions.
Acute coronary syndromes, or heart attacks, are on the rise among younger individuals, particularly in our country. Studies of the Asian-Indian migrant population have revealed a probable racial predisposition for premature CAD. However, the majority of the risk can still be attributed to the increased incidence of conventional CAD risk factors in young people, such as obesity, inactivity, diabetes, hypertension, and dyslipidaemia.
Smoking and substance abuse are resulting in more heart disease among the young. Lesser-discussed, unconventional risk factors, such as mental stress, lack of healthy employment practices, environmental pollution, and lack of proper food safety regulations, are in fact contributing significantly to this silent epidemic. COVID-19 infection as well as vaccination were widely attributed as causes of heart attacks in young people, but without adequate scientific evidence.

Women can play a major role in preventing as well as eliminating Chagas Disease, a potentially life-threatening neglected tropical disease that affects 8 million people globally and causes 10,000 deaths every year, according to UN agencies.
World Chagas Disease Day is observed every year on April 14 to raise awareness around the disease, and the impact it has on lives.
In a statement, the Pan American Health Organization (PAHO) and the Global Chagas Coalition urged health authorities to make women central to the fight against the disease and to empower them to make early detection, prevention, and care.
“Eliminating Chagas disease as a public health problem requires placing women at the center of diagnosis, treatment, and care strategies,” said Dr. Jarbas Barbosa, PAHO Director.
“Ensuring timely access to quality health services, particularly for women of reproductive age, is essential to prevent new infections and advance toward the elimination of congenital Chagas disease in the Region of the Americas,” he added.
Chagas disease, also known as American trypanosomiasis, is a illness caused by the parasite Trypanosoma cruzi, and is primarily transmitted by triatomine insect vectors.
It gets spread through
If left untreated, one third of infected people—including women and the children they carry—will develop life-altering heart, digestive, and even neurological conditions, and may even become fatal.
Once endemic to 21 countries in Latin America, the disease has now spread globally due to migration. It is now a global health concern with cases found in 44 countries including the US, Canada, Europe, Australia, and Japan.
World Chagas Disease Day was celebrated for the first time in 2020.
The theme this year is “Women at the heart of care, protecting the next generation” and underscores the key role women play in family and community caregiving, as well as their greater interaction with health services, particularly during pregnancy.
Chagas Disease: Role Of Women
According to the World Health Organization (WHO), about 2 million women aged 15-44 years are living with Trypanosoma cruzi infection worldwide.
Congenital transmission or mother-to-child transmission remains a major challenge, occurring in about 3–5 percent of pregnancies. However, it also provides a key opportunity for effective intervention.
The transmission cycle of the disease can be effectively broken by
“On the contrary, it represents a strategic opportunity to strengthen more equitable, accessible, and responsive health systems that recognize and respect women’s needs.”
