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.

Kidneys are extraordinary organs that perform critical tasks on a continual basis, e.g., filtering out waste, keeping electrolytes balanced, controlling blood pressure, and providing metabolic stability.

However, many people don’t pay enough attention to keeping their kidneys healthy until they discover that substantial damage has already happened.

Some of the most prevalent and underestimated threats to kidney functioning include uncontrolled blood pressure, chronic anxiety, and unhealthy living.

The Effect Of Hypertension On Kidney Function

Hypertension (high blood pressure) is considered one of the most prevalent causes of CKD (chronic kidney disease) worldwide.

The kidneys need the support of a complicated design of tiny blood vessels to carry out their task of removing waste from the bloodstream. An ongoing and increased blood pressure level will slowly harm these small blood vessels by reducing their ability to function normally. As time passes, this injury will result in scar formation of the kidney tissue, causing a continual decline in the kidney’s ability to filter.

Hypertension is known as a silent killer because it frequently has no symptoms for many years. By the time someone experiences symptoms of high blood pressure, their kidneys may have already been damaged for a considerable period.

Chronic stress is often overlooked as an indirect cause of kidney damage. When we are under chronic stress, our sympathetic nervous system is activated, and the amount of stress hormones (cortisol and adrenaline) in our bodies increases.

These physiological changes lead to prolonged increases in blood pressure and blood glucose; both of these risk factors are bad for our kidneys. Chronic stress may cause people to engage in unhealthy coping strategies like poor diet, smoking, consuming alcohol, or not being physically active, which also increases their risk of kidney damage.

Our long-term kidney function is largely determined by lifestyle choices, including our dietary habits. Diets high in sodium, processed foods, and unhealthy fats increase the probability that you will develop hypertension, metabolic disorders, or some combination of both of these, which puts even more strain on your kidneys.

The sedentary lifestyle associated with obesity, insulin resistance, and cardiovascular disease are all significant contributors to chronic kidney disease. Dehydration, taking large amounts of over-the-counter medications (especially NSAIDs), and using tobacco products are all additional risk factors for progressive loss of kidney function.

Preventative Interventions For Kidney Health

Many of these risk factors can be addressed through prevention.

Regular monitoring of blood pressure, using mindfulness and other methods to manage stress levels, and maintaining a healthy diet full of fruits, vegetables, and whole grains will all help to reduce the strain on your kidneys.

Regular health screenings for people who have some of the above-mentioned risk factors (e.g., diabetes, high blood pressure, etc.) will give people an opportunity to identify problems early, giving them time to adjust their lifestyle or possibly seek some other type of treatment (e.g., taking medication).

The Importance of Early Awareness and Intervention

Gaining and maintaining awareness of what contributes to the health of the kidneys can help protect the kidneys.

Gaining awareness of and taking action against hidden risks, such as high blood pressure or chronic stress, and making positive changes to your lifestyle will help maintain kidney function and minimize the likelihood of developing long-term complications in the future.

Early intervention is the most effective method for protecting the health of your kidneys.

India is surely winning the battle against malaria. However, the disease is still around. Medicines and nets help a lot, but doctors point to something else. They say the real cure starts before you even get sick. It all comes down to keeping your local area totally clean.

This fever only spreads through female Anopheles mosquitoes. They do not need big ponds to multiply. A little dirty water trapped inside an old tyre, a thrown-away plastic cup, or a coconut shell is all they need. That is where the cycle of malaria starts. Within days, larvae turn into mosquitoes, and the infection begins to move through nearby homes. This is why many doctors put it plainly. Treating a patient comes later. Stopping the mosquito from breeding is the foundation of the battle against malaria, and that depends on everyday cleanliness by everybody residing in each lane and building.

The official health data brings major relief. Malaria is finally losing its grip. Fresh WHO reports prove this fact. In 2017, India struggled with nearly 64 lakh cases. But the figures show a steep fall in the number of cases by 2023. The total patient count stood at just 20 lakh. We are looking at a clear 69 percent drop in a very short time. Seeing this huge improvement, the WHO took India off its critical 'High Burden to High Impact' list in 2024.

Data released by the government of India tells a similar story. Figures from the National Center for Vector-Borne Diseases Control under the Union Health Ministry show a decline in the number of deaths by more than 78 percent between 2015 and 2023. The target now is clear. The government has set a very clear target. They want malaria cases to hit zero by 2027. After that, the final goal is to wipe out this disease from the entire country by 2030.

We are winning this fight, but the danger is still far from over. Cover your water tanks properly. Clean the open drains. Do not let rainwater collect near your house. These small daily habits easily stop the disease from spreading.

However, the health department alone cannot achieve this massive target. Fogging and spraying of chemicals done by municipal bodies only kill adult mosquitoes that are already flying. The fight is local. If water tanks are shut tight, drains are not clogged, and garbage isn’t left to collect rainwater, the danger drops quickly.

When a society maintains clean surroundings, it naturally destroys the breeding grounds for mosquitoes. If the mosquitoes cannot breed, the chain of infection breaks automatically. As India moves closer to its 2030 malaria-free goal, keeping our streets, parks, and homes clean is no longer just a civic duty. It is our absolute first line of medical defense against a deadly disease.

Plastic containers have been discouraged for a long time now, especially for heating food or storing hot food. Studies have associated this habit with a heightened risk of cancer, but now an expert has specifically spoken about black plastic containers and what makes them worse for you. According to Dr Rakesh Kumar Sharma, Senior Consultant Medical Oncologist at M | O | C Cancer Care & Research Centre, Gurugram, cooking or heating food in black containers could be very harmful to your body. Read on to find out how.

Dr Sharma, in an interview with Health and Me, said that cooking food in black plastic receptacles could lead to greater amounts of certain chemicals making their way into your body; however, there currently exists no scientific evidence confirming that this daily activity increases your risk of cancer.

Why is black plastic worse than others?

Dr Sharma explained that black takeaway containers usually consist of recycled plastics, such as e-waste, and can contain flame retardants, BPA, phthalates, etc. When heated in contact with food, especially if the food is hot, fatty, or acidic, more chemicals could potentially make their way into the food from the container. In this way, it may, over time, heighten your risk of developing a malignant tumour.

Black containers are coloured using carbon black, which is included in Group 2B of possible human carcinogens according to IARC, as shown in both animal and limited human research. Moreover, recycled black plastics could contain polycyclic aromatic hydrocarbons and decaBDE, which have shown carcinogenic effects in experiments. This makes black plastic containers worse than other coloured counterparts. Yet, heating food in a plastic container of any colour is not deemed safe.

Do studies verify the side effects of heating food in plastic containers?

Experimental studies conducted in laboratories on microwaveable plastic receptacles reveal the migration of tens of chemicals and millions of microplastics per litre of the food simulant. However, a recent study in 2024 reported that containers labelled as microwave-safe in Korea adhered to contemporary safety standards for these levels, and total exposure fell within safe limits.

Leading cancer associations have confirmed that the usage of plastic packaging, even in microwave applications, has not been linked with increased cancer risks in humans, although there is ongoing research in areas such as black plastics. However, precautionary measures are suggested by experts as a better strategy due to the difficulties of directly studying long-term, low-level exposure to chemical compounds.

How to reduce cancer risk?

When it comes to reducing cancer risk, most doctors recommend quitting smoking and limiting alcohol intake. However, Dr Sharma listed some basic kitchen and eating habits that may come to your rescue:

1. Avoid cooking food in black plastic packaging, particularly if the food is oily or acidic.
2. Move hot food into glass, ceramic, or stainless steel containers for reheating.
3. Only use microwave-safe containers and discard any broken plastic containers.
