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.

Ten-year-old Myla from the UK's North Yorkshire, with severe eye strain, was diagnosed with a severe brain tumor that led to her death.
The young girl had been suffering from headaches and dizziness, which were dismissed as mere eye strain due to playing on her iPad too much.
Thinking that she needed eyeglasses, her parents took her for an eye appointment, where she was diagnosed with an aggressive diffuse midline glioma — a type of brain tumor.
Myla was diagnosed with a 7-10cm tumor and was rushed to Sheffield Children's Hospital for an operation to remove 60 per cent of the mass. The youngster underwent a grueling 30 rounds of radiotherapy but tragically passed away on January 15, The Mirror.co.uk reported.
Healthandme spoke to health experts to understand the role of eye strain and brain tumors.
The health experts noted that although prolonged exposure to digital screens can raise the risk of vision problems, they cannot cause brain tumors.
"Eye strain is most commonly linked to prolonged screen use, poor ergonomics, or uncorrected vision, and in the vast majority of cases, it is not a sign of brain cancer," Dr. Parul Maheshwari Sharma, Ophthalmologist and Principal Director & HOD - at Fortis Gurugram, told HealthandMe.
"The likelihood of experiencing eye strain being an indication of brain cancer is minimal," added Dr. Mahipal Singh Sachdev, Chairman & Medical Director, Centre For Sight Group of Eye Hospitals.
The doctors explained that brain tumors are rarely present as simple eye strain; they are usually associated with additional symptoms such as:
Eye strain, also referred to as digital eye strain or computer vision syndrome, is caused by staring at screens for extended periods of time and decreased blinking.
It generally occurs due to benign factors such as excessive screen time, dry eye, or uncorrected vision.
While prolonged screen use can cause discomfort, dry eyes, and temporary blurred vision, it does not lead to the development of cancer.
"There is no evidence to suggest that screen-induced eye strain can cause brain tumors," Dr Sharma said.
"Although there may be visual changes due to a tumor that involves the optic nerve or hypothalamus, simple eye strain is not indicative of brain tumors and would not be considered an early warning of a brain tumor. There is an extremely low probability that eye strain will be due to a brain tumor," Dr. Sachdev told HealthandMe.
However, the experts agreed that long screen time can lead to severe eye strain.
Brain tumors are generally attributed to genetics, exposure to radiation, or other unknown factors.
Numerous types of red flags could indicate the presence of a serious neurological disorder. Some examples include

Ladies, does it ever happen to you that you are not on your period, not PMSing, and still feel moody and upset? Well, as it turns out, experts say that there could be a very simple reason for this. According to researchers at the University of Connecticut, even mild dehydration could be responsible for mood changes in women. Not only this, even 1.36 per cent dehydration can affect your mood, ability to think and energy levels. The Daily Mail notes that a loss of 1.5 per cent of normal water volume levels in the body can be classified as mild dehydration, and its adverse effects can linger for some time.

In women, the adverse effects of dehydration can be serious. Experts say that the effects are more intense in women, and they came to this conclusion after analysing the results of tests, which revealed that it does not matter if a person walks for 40 minutes on a treadmill or is in a state of rest — if an individual is even slightly thirsty, the adverse effects will be the same.
Research shows that even 1.36 per cent dehydration is enough to cause the following problems:
Is thirst the same as dehydration?
Lead researcher of the study, Lawrence Armstrong, noted that a sensation of thirst does not appear until a person is one or two per cent dehydrated. By then, it starts to set in and act up, adversely impacting how the mind and body perform. Dehydration can affect everyone, which is why it is just as important for people in desk jobs to stay hydrated as it is for marathon runners.

In this research, experts put participants through a series of tests evaluating their concentration, vigilance, reaction time, reasoning, memory and learning. The results were then compared with those of people who were not dehydrated. In younger women, mild dehydration resulted in fatigue, headaches and concentration difficulties. Women also found basic tasks more difficult to execute than usual. On the other hand, young men noted some difficulty in performing mental tasks — they experienced anxiety, fatigue and tension in the process. Mood changes were more prominent in women than in men.
The oral microbiome is the community of bacteria, fungi, and other microorganisms that naturally live in the mouth — on the teeth, gums, tongue, and cheeks. More than
700 species are known to exist, most of which are harmless and many beneficial.
However, problems arise when harmful bacteria outnumber protective ones, leading to gum inflammation or periodontal disease. During pregnancy, hormonal changes increase blood flow to the gums and alter immune responses. As a result, many women notice bleeding, swelling, or sensitivity in the gums — a condition known as pregnancy gingivitis.
This is common and reflects physiological changes rather than poor hygiene.
Pregnancy is a systemic state in which the immune system, circulation, and inflammation are closely interconnected. Chronic gum inflammation can release inflammatory mediators into the bloodstream.
In research settings, certain oral bacteria have also been detected in placental tissues from complicated pregnancies. This suggests a biological link between oral health and
placental function, although the exact pathways are still being studied.
Importantly, this relationship reflects association rather than direct causation.
The placenta is an active organ that regulates oxygen and nutrient transfer, hormone production, and immune protection for the developing baby.
Healthy placental development supports:
Up to 60–75 percent of pregnant women experience some degree of gum inflammation. Common changes include:
Research from India and globally shows associations between periodontal disease and higher risks of preterm birth, low birth weight, and preeclampsia. Meta-analyses
suggest a modest increase in risk (around 1.5–2 times).
However, pregnancy complications are multifactorial. Oral disease alone does not directly cause these outcomes. Genetics, nutrition, metabolic health, and placental
biology all play important roles.
Treating gum disease improves oral health and reduces inflammation, though studies show mixed evidence on whether it directly lowers preterm birth risk. The goal is
prevention, awareness, and overall maternal health.
Daily oral care:
Pregnancy already carries emotional and physical changes, and dental symptoms can add anxiety. Support from partners and family members helps reduce mental load.
Stress can influence immunity and inflammation. Adequate rest, gentle activity such as walking or prenatal yoga, and open communication with healthcare providers
support both oral and overall health.
Seek professional advice if you notice:
Pregnancy is a time when different systems of the body work in close coordination. Oral health, immune balance, and placental function are part of the same continuum.
Gentle attention to gum health is not about perfection. It is about creating supportive conditions for a healthy pregnancy and a healthy baby.
