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 Three Stress Responses: Fight, Flight, and Freeze

1. Fight

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.

2. Fight

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.

3. Freeze

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.

What Happens in the Body During A Stressful Event?

When faced with a stressor, the autonomic nervous system (ANS) activates, triggering physiological changes, including:

• Increased heart rate and breathing: The body pumps more oxygen to muscles and the brain in case action is needed.
• Muscle tension: The body prepares for movement, sometimes causing trembling or stiffness.
• Dilated pupils: Vision sharpens to detect potential threats.
• Dry mouth: Saliva production decreases as the body redirects energy to essential functions.
• Changes in skin tone: Blood flow is directed to vital organs, sometimes making the skin appear pale or flushed.

For those experiencing the freeze response, the body undergoes a different reaction, often reducing heart rate and causing physical immobility rather than heightened activation.

Strategies for Coping and Managing the Stress Response

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.

1. Moving to a Safe Space

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.

2. Practicing Controlled Breathing

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.

3. Engaging in Physical Activity

This helps release pent-up energy and aids in the endorphin cascade, natural boosters for our mood.

4. Seeking Social Support

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.

When to Seek Professional Help

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.

Higher temperatures in the US could increase heat-related heart disease by 200 per cent by 2050, according to an alarming study.

The research, published in JAMA Cardiology, predicts rising temperatures driven by climate change will dramatically increase heat-related heart disease in the US.

It is already known that extreme heat is detrimental to heart health and can potentially trigger heart attacks and other cardiovascular events.

"But this study is the first to map out exactly how bad the problem could get—county by county, across the US. It also highlighted how states with lower median household incomes are likely to face higher heat-related heart disease burden," said Gokul Parameswaran, research associate at the Case Western Reserve School of Medicine's Cardiovascular Research Institute and the study's lead author.

Regional Hot Spots

Researchers analyzed heart disease data in each county in the contiguous US from 2010 to 2016 to develop projections through 2050.

They found that the Pacific Northwest has the highest heat-related heart disease rate in the country. Southern states, however, are projected to see the steepest increases by 2050.

"Climate change is not just an environmental issue—it is a health equity crisis, and prioritizing vulnerable communities must be at the center of any heat mitigation strategy," said Salil Deo, associate professor in the Department of Surgery.

The study also found that aging — independent of temperature increases — will contribute an additional 34 per cent increase in heat-related heart disease by 2050, simply because there will be more older adults by then.

Heat Events In The US

The study comes amidst more frequent heat events in the US, which is also lasting longer, and the temperatures during heat events are going up.

The past 10 years, from 2015 to 2024, were the hottest on record globally. But in cities across the United States, the average rate of extreme heat events increased from two per year in the 1960s to 10 per year between 2010 and 2020, according to Center for Climate and Energy Solutions (C2ES), a Washington-based NGO.

Additionally, as of 2024, the average length of heat-wave season in the US has increased by 46 days since the 1960s.

How Does Heat Raise Heart Risks?

According to the Centers for Disease Control and Prevention, when temperatures rise, the heart must work harder to keep the body cool, and the likelihood of developing sudden clots in the bloodstream increases.

This extra stress on the heart due to high heat may lead to heart attacks or sudden worsening of heart disease, especially in the elderly or those with prior heart conditions.

How To Tackle The Risk

• Expanding green spaces and tree cover in urban areas could help reduce temperature-related adverse effects.
• Expanding access to cooling centers and air-conditioning assistance programs for low-income communities can also help bridge the gap in underserved communities.

"Climate change is not a distant, abstract threat," said Sanjay Rajagopalan, director of the Cardiovascular Research Institute and chief of Cardiovascular Medicine at University Hospitals Harrington Heart & Vascular Institute.

"It is a present and growing danger to the hearts of every American, and it is coming for the most vulnerable among us first. The choices made today about greenhouse gas emissions, urban planning, and health care policy will determine whether tens of thousands of Americans live or die from heat-related heart disease by 2050," he added.

Diabetes is not only a disorder affecting blood sugar levels, but it also increases the risk of heart disease. People who have diabetes are more prone to get affected by heart attack, stroke, high blood pressure, and blockage of arteries than people without diabetes. Because of this strong link, diabetes care needs a focus on both blood sugar control and heart care.

One of the biggest improvements in diabetes care is the use of GLP-1 receptor agonist therapies. These medications not only help to control sugars but also reduce the risk of heart disease. When a person combines GLP-1 treatment along with a healthy lifestyle, they can improve their overall well-being and lead a good quality of life.

Understanding the Link Between Type 2 Diabetes and Heart Disease

Type 2 diabetes and heart disease are interlinked. Diabetes increases heart disease risk by 2 to 4 times. Over a period of time, when the sugars are chronically high, blood vessels and nerves that support the heart get damaged. Many individuals with diabetes also have additional risk factors, such as:

• Obesity
• High blood pressure
• High cholesterol
• Physical inactivity

These conditions can make a person vulnerable to a heart attack and stroke. Studies show that people with Type 2 diabetes are nearly twice as likely to develop heart disease compared to those without diabetes.

What Are GLP-1 Therapies?

GLP-1 receptor agonists are medications to control high blood sugar in people with type 2 diabetes. These therapies help by:

• Increasing insulin release when blood sugar rises
• Delaying stomach emptying
• Reducing appetite
• Decreasing glucagon production
• Improving weight loss

GLP-1 therapies help control blood sugar. Beyond this, these treatment regimens provide many more benefits. Research shows that these medications can reduce the risk of major cardiovascular events such as heart attack and stroke.

In addition, GLP-1 therapies help in weight reduction. Obesity is also linked to diabetes and heart disease. Hence, GLP-1 therapies help to reduce weight and the risk of developing heart diseases.

Importance of Lifestyle Changes

Medications are important in controlling blood sugars. However, the medication therapies need to be combined with a healthy lifestyle, which can remain the foundation of diabetes and heart disease care.

Healthy Nutrition

A balanced, healthy plate can improve blood sugar, cholesterol, and blood pressure levels. Individuals with diabetes are encouraged to include:

Whole grains

Vegetables and fruits

Lean proteins

Nuts and seeds

Healthy fats

By restricting sugars, processed and ultra-processed foods, extra salt, and unhealthy trans-fats, one can reduce weight and support heart health.

Regular Physical Activity

Regularized physical activity routines help improve insulin sensitivity and strengthen the heart. Activities like walking, cycling, swimming, yoga, and strength training can help reduce the risk of heart disease. Experts generally recommend at least 150 minutes of moderate exercise every week.

Weight Management

Even small amounts of weight loss can improve blood sugar control and reduce stress on the heart. The combination of GLP-1 therapies, healthy lifestyle, controlled eating, and regular exercise gives better long-term results.

Conclusion

Type 2 diabetes and heart disease are closely interlinked, making complete diabetes care essential. GLP-1 therapies are changing diabetes management by offering benefits beyond glycemic control, including heart protection and weight reduction.

However, tablets and medicines alone cannot do all the work. Healthy lifestyle changes, such as balanced nutrition, regular physical activity, and proper weight management, must contribute equally. GLP-1 therapies and lifestyle changes can significantly reduce heart-related risks and improve overall well-being in individuals with Type 2 diabetes.

Multiple Sclerosis (MS) is a chronic neurological condition in which the immune system attacks the central nervous system, leading to symptoms such as fatigue, chronic pain, bladder disturbances, gait imbalance, and blurry vision, among others. These symptoms fluctuate, progress over time, become life-limiting, and are not always outwardly visible.

Growing evidence shows that early diagnosis and timely initiation of high-efficacy therapies (HETs) can slow disease progression, reduce relapses, and preserve long-term neurological function. For many individuals living with MS, the struggle goes beyond simply managing their condition. It is also about whether the full impact of the disease is adequately recognized and understood by policymakers, healthcare systems, and the public at large.

Although MS is recognized as a disability under the Rights of Persons with Disabilities (RPwD) Act, 2016, people living with MS (PwMS) continue to face difficulties accessing disability-related support because their symptoms are not always consistent, visible, or measurable during assessment. This is particularly relevant in a condition like MS, where some of the most disabling symptoms remain invisible.

Living with an Unseen Disability

The effects of MS extend far beyond mobility issues alone. Fatigue, brain fog, memory problems, neuropathic pain, bladder dysfunction, visual disturbances, and emotional strain can significantly hinder a person's ability to work, engage socially, manage responsibilities, and fully participate in everyday activities.

One of the less understood aspects of MS is cognitive impairment, which affects a significant proportion of PwMS. MS causes inflammation in the brain and contributes to brain volume loss, thereby slowing processing speed, affecting concentration, impairing memory, and making planning or multitasking increasingly difficult. Even routine activities such as maintaining conversations, remembering instructions, or completing everyday tasks may become mentally exhausting.

Because many of these symptoms are episodic, variable, or invisible, PwMS may sometimes delay seeking specialist care, while the impact of the disease may also be underestimated by those around them. Yet, MS disease activity can continue even when symptoms appear intermittent or mild.

In MS, treatment decisions regarding the early initiation of the appropriate therapy (platform disease-modifying therapy versus high-efficacy therapy) can meaningfully influence long-term outcomes and quality of life.

Because slowing disease progression often requires highly potent intervention, evaluating a drug’s long-term safety profile becomes just as critical as its efficacy. Certain therapies may carry a risk of progressive multifocal leukoencephalopathy (PML)—a rare and potentially fatal viral brain infection that occurs under severe immunosuppression. Therefore, choosing a high-efficacy treatment with a favorable long-term safety profile is paramount.

When Clinical Reality and Functional Recognition Diverge

MS is inherently unpredictable. A person may appear physically stable during one evaluation but experience significant neurological difficulties during a relapse or disease flare-up.

In clinical practice, neurologists evaluate MS through disease progression, relapse patterns, imaging findings, and the EDSS scale (a standardized method used to quantify and measure the level of disability in PwMS).

Looking Ahead

Improving understanding of invisible symptoms in MS is important not only for social awareness but also for enabling patients to access timely care. Greater clarity, consistency, and sensitivity in approaches to chronic neurological conditions can help ensure that PwMS are better supported across healthcare, workplace, and social settings.

Earlier diagnosis, timely intervention, and stronger recognition of the day-to-day realities of living with MS can together help patients preserve dignity, maintain independence, and achieve better long-term outcomes.
