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.

While research shows women need more sleep than men due to brain function, hormones, and multitasking, females around the globe are struggling to get enough sleep, according to experts.
A 2016 study by the Sleep Research Centre at the UK’s Loughborough University found that women needed 20 minutes more sleep because of multitasking and performing more complex brain tasks during the day.
But, the American Academy of Sleep Medicine (AASM), revealed that an estimated 30 percent of women fail to get sufficient sleep.
Hormones, mood disorders, and caregiving responsibilities, coupled with professional pressures and stress, are the major reasons driving up insomnia and other sleep issues among women.
“Women around the world face a higher burden of sleep difficulties because their sleep cycles are tightly interlinked with hormonal shifts that occur throughout life,” Dr. Janhvi Siroya Shah, Sleep Specialist from the University of Bern, Switzerland, told HealthandMe.
The gender gap in sleep is real, as revealed by the recent ResMed Global Sleep Survey 2026, which showed that 56 percent of women get a good night's sleep only four days or fewer per week, compared to 50 percent of men.
Women were also 48 percent more likely to report problems falling asleep than men (42 percent). More than 50 percent of women felt waking up not feeling rested for 1-2 nights per week or more, compared to 46 percent of men.
The study flagged stress or anxiety as the biggest barrier to consistent, quality sleep (39 per cent), followed by work-related responsibilities (37 per cent) and household duties (31 per cent) among women.
Speaking to HealthandMe, Dr. Kirti Kadian, from the Department of Pulmonary Critical Care & Sleep Medicine at AIIMS Bhopal, said: “Women experience disproportionate sleep challenges globally, largely because their bodies undergo repeated physiological transitions that influence how sleep is regulated.”
The experts cited the main reasons as
All these factors can alter mood regulation, increase nighttime alertness, and disrupt the architecture of sleep itself.
Dr Kadian said that hormonal fluctuations across the life course -- especially during the menopausal transition -- can affect circadian rhythm, airway stability, pain sensitivity, and the nervous system’s response to stress.
“When these biological changes coincide with external stressors, such as multitasking, emotional labor or caregiving demands, women become far more vulnerable to insomnia and unrefreshing sleep,” Shah said.
The prevalence of sleep disorders increases from about 16–42 percent in pre-menopause to around 39–47 percent in peri-menopause and up to 35–69 percent in post-menopause, indicating that sleep disturbances become more common as women progress through different reproductive stages.
“Declining levels of estrogen and progesterone can disrupt the body’s sleep regulation and trigger symptoms like hot flashes and night sweats, while reduced melatonin may make it harder to fall and stay asleep,” Dr. Kadian explained.
In addition, certain medical conditions that are more common in women, such as thyroid disorders, anemia, and autoimmune diseases, can also negatively affect sleep and overall health.
Poor sleep also significantly affects both physical and mental health, increasing the risk of

While early-stage research raised hopes of oral semaglutide (GLP-1 pill) slowing down the progression of Alzheimer’s disease, results of a new large-scale clinical trial have rendered it ineffective.
Evoke and Evoke+ -- the randomized, double-blind, placebo-controlled phase 3 trials conducted across 566 sites in 40 countries -- showed that semaglutide led to no significant difference after two years.
The findings, published in the Lancet journal, however, revealed that the popular weight loss drug can lead to significant reductions in several biological markers of Alzheimer’s disease.
Yet, it did not help slow the progression of the neurodegenerative disease, said an international team of researchers, including those from the University of California-San Diego.
"Oral semaglutide was not efficacious in slowing clinical progression in participants with early Alzheimer's disease," they said in the paper.
"Safety and tolerability of semaglutide in early Alzheimer's disease is consistent with studies in other indications," the team added.
The studies are the first major phase 3 trials to investigate this possibility in people with early Alzheimer’s disease.
The researchers conducted the trial on about 3,800 patients aged 55-85 years. The patients received either up to 14 mg of oral semaglutide daily or a placebo pill.
After two years, no significant difference was seen in slowing down the cognitive disease's progression in patients taking semaglutide and patients taking the placebo.
"The results of the large evoke(+) trials do not support the efficacy of 14 mg/day of semaglutide given for up to 156 weeks in participants with biomarker-confirmed Alzheimer's disease in the MCI or mild dementia stage," the researchers said.
While “GLP-1 [drugs] have given us so many wonderful results," the trial results are "disappointing,” and “a setback for the field”, endocrinologist Daniel Drucker was quoted as saying to the Scientific American.
Drucker says there are many potential explanations why oral semaglutide didn’t work as hoped. The fatty-acid structure surrounding semaglutide might have prevented it from being able to penetrate certain brain regions, such as the hippocampus, which controls memory and cognitive function.
Alzheimer's disease is a progressive neurodegenerative disease characterised by gradual cognitive and functional decline.
It is one of the most common forms of dementia and mostly affects adults over the age of 65.
Over seven million people in the US, 65 and older, live with the condition, and over 100,00 die from it annually.
The disease is believed to be caused by the development of toxic amyloid and beta proteins in the brain, which can accumulate and damage cells responsible for memory.
Early symptoms of Alzheimer's disease include forgetting recent events or conversations. Other signs include:

In the year 1947, on the remote Scottish island of Jura, George Orwell sat hunched over a typewriter in a farmhouse, engaged in a desperate race against time to finish his masterpiece, 1984, while a ‘slow-motion plague’ consumed his lungs.
The man who was born in Motihari, Bihar, was suffering from tuberculosis. He would cough up blood and frequently collapse out of sheer exhaustion, even as he typed the final warnings of a dystopian future. He finished the book in December 1948 and died just over a year later.
Orwell’s story is a haunting reminder that TB has always been a disease of the displaced. As we approach World Tuberculosis Day this year with the theme ‘Yes! We Can End TB: Led by countries, powered by people, we face a sobering reality.
We have the modern tools that Orwell lacked, but the global narrative remains trapped in an outdated cycle where technological potential far outstrips operational reality. To end this disease, we must stop viewing TB through a narrow clinical lens and start addressing the systemic inefficiencies that leave out millions.
For decades, a diagnosis of drug-resistant TB (DR-TB) was a near-death sentence even with treatment. Patients faced a grueling 18 to 24-month treatment regimen involving thousands of pills and daily painful injections that often caused permanent side effects like deafness.
With the introduction of the BPaLM regimen (Bedaquiline, Pretomanid, Linezolid, and Moxifloxacin), this tide seems to have turned. The all-oral four-drug treatment, touted as a medical miracle, has slashed recovery time for drug-resistant strains to just six months.
However, even a magic pill cannot overcome a broken system. We must distinguish between clinical success and social success. A patient might technically be cured of the bacteria, but if they lose their job or suffer from social stigma during those six months, the system has still failed them.
Statistically, men bear a higher burden of TB, yet they are often the hardest to bring into the care net. According to the World Health Organization (WHO), men account for approximately 55 per cent of all TB cases globally, compared to 33 per cent for women and 12 per cent for children.
This is not a biological accident; it is a structural failure. Gendered social norms often prevent men from seeking care until the disease is advanced. As primary earners, the prospect of losing wages – combined with the stigma of diagnosis – creates a powerful disincentive to visit a clinic. To be truly people-centered, we must move away from static clinic hours and towards flexible, community-based care that reaches men at places where they work.
Treating TB in isolation is an outdated strategy. We see patients suffering from a double burden because TB is usually accompanied by diabetes, malnutrition, or even HIV.
Despite this, our medical systems remain stubbornly reserved. A patient is often forced to navigate fragmented clinics that rarely communicate. Integration is the only way to ensure we treat the whole person, not just the pathogen.
The path forward requires us to acknowledge that we cannot end TB by looking only at the lungs; we must look at the lives of those affected. The end of TB is a matter of leadership and courage to fix the systems that hold medical science back.
As we look towards World Tuberculosis Day, let us not just renew our commitments; let us hold our systems to account. The human cost of cure is currently too high, not because of the medicine, but because of the world in which the medicine is delivered.
As we honor World Tuberculosis Day, let us ensure that no one else has to choose between finishing their life’s work and surviving a curable disease. Curing tuberculosis is no longer a biological mystery; it is a test of our collective humanity.
