Stress is an inevitable part of life, but its consequences are not just mood swings and mental fatigue. Continual stress makes people produce extra cortisol, a hormone that has a critical role in adapting to short-term challenges, but chronically in high quantities it tends to cause harm to the body causing lots of physical and mental disorders.
The adrenal glands produce cortisol, which helps the body control its "fight, flight, or freeze" response. Cortisol temporarily adjusts blood sugar levels, maintains blood pressure, and assists the immune system, among other functions, in short spurts. But when stress persists, cortisol remains high, and necessary functions of the body are interfered with and rendered more susceptible to disease.
According to one survey conducted by the American Psychological Association, stress negatively affects a third of Americans' physical health. Concerns are reinforced by research where studies have shown 80% of primary care visits are stress-related.
But why does stress have such a profound impact? Elevated cortisol limits the immune system's ability to fight infections, disrupts hormonal balance, and triggers inflammation. Over time, these changes can lead to serious health complications.
Do you have involuntary eye spasms? These harmless but annoying twitches often indicate elevated cortisol. The tiny muscles around the eyes are extremely sensitive to stress, contracting or spasming because of cortisol's stimulant-like effects.
Your skin often reflects what is going on inside your body, and chronic stress can cause inflammatory skin conditions. Elevated cortisol levels stimulate oil production, which exacerbates acne. It also slows down the healing process, worsens conditions like eczema, and contributes to general irritation of the skin.
It also interferes with the body's balance of salt and water, which causes fluid retention and bloating. Excess cortisol also slows down blood flow to the digestive system, which further weakens gut bacteria and causes poor digestion, excess gas, and abdominal discomfort.
High cortisol stimulates the production of insulin, which can cause blood sugar to drop, making people want to eat sugary, high-fat foods. For many, this becomes an excuse to stress-eat and gain weight. For others, the opposite is true: their appetite disappears under stress, causing them to lose weight.
If you’re noticing random bruises, elevated cortisol could be the culprit. This hormone weakens skin proteins and the walls of small blood vessels, making your skin more fragile and prone to damage.
Do you feel rundown or experience muscle aches, fatigue, or upset stomach regularly? Elevated cortisol mimics cold-like symptoms. Long-term stress also weakens the immune system, making you more susceptible to infections.

Chronic stress can damage your eyesight. Elevated cortisol disrupts blood flow to the eyes, increases eye pressure, and raises the risk of glaucoma. Symptoms like dry eyes, blurred vision, and light sensitivity are also common.
Irregular Menstrual Cycles that disrupt the menstrual period. In females, this leads to hormonal distress causing irregular or missed periods. Over time, it may also disturb fertility.
If you hear ringing, buzzing, or hissing sounds without an apparent source, stress might be the culprit. Cortisol affects the auditory system by interfering with blood flow and nerve function and could be the trigger for tinnitus.
Increased levels of cortisol contribute to inflammation that can exacerbate conditions such as arthritis and promote the development of heart disease. Chronic inflammation is also associated with mental health conditions, including anxiety and depression.
Left unchecked, high cortisol levels can lead to more than just short-term discomfort. Chronic stress has been associated with serious conditions such as heart disease, psychiatric disorders, and metabolic syndromes. A 2013 study published in JAMA Internal Medicine underlined the link between stress and physical health, with recent research in Neurobiology of Stres supporting these findings.
Managing stress and cortisol levels is essential for maintaining overall health. One effective approach is practicing mindfulness through meditation or yoga, which helps lower cortisol by calming the mind and promoting relaxation. Regular physical exercise, especially aerobic activities, helps reduce stress hormones and boosts endorphins. Prioritizing sleep is crucial, as lack of rest can increase cortisol levels; aim for 7-9 hours per night.
Another remedy is an overall balanced diet full of anti-inflammatory foods like fruits, vegetables, and whole grains that could manage cortisol production. Finally, it would prevent burnout and chronic stress if proper boundaries were set at work and in personal life.

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.

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.
