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.

Can Chinese medicine cure baldness? Baldness has long been dealt as a matter of shame over health. Products focus on hiding the bald patch rather than curing it. Baldness has in the past made global headlines when South Korean president Lee Jae Myung said 'Baldness is the new enemy' and suggested that insurance should cover the treatment as a part of medical treatment.
Androgenetic alopecia (AGA), better known as pattern hair loss, is the most common form of hair thinning worldwide. While medications like finasteride and minoxidil remain the standard line of treatment, concerns around side effects, lifelong use, and mixed results have led many people to explore gentler, more holistic alternatives.
A new scientific review now suggests that Polygonum multiflorum—a root used in traditional Chinese medicine for over a thousand years—may hold real promise in managing AGA. Historically described as a remedy that can “blacken hair and nourish essence,” the herb is gaining renewed attention as modern research begins to unpack how it actually works at a biological level.
Most conventional hair-loss treatments target a single biological mechanism. Polygonum multiflorum, however, appears to work on several fronts at once. According to the review, the herb helps reduce the activity of dihydrotestosterone (DHT), a hormone strongly associated with hair follicle shrinkage in AGA.
At the same time, it protects hair follicle cells from premature cell death and activates key growth-related signalling pathways, including Wnt and Sonic Hedgehog (Shh), both crucial for maintaining a healthy hair growth cycle. The herb may also improve scalp blood circulation, potentially enhancing the delivery of oxygen and nutrients to hair follicles—an often overlooked factor in hair thinning.
“Our analysis bridges ancient wisdom and modern science,” said Han Bixian, the lead author of the review published in the Journal of Holistic Integrative Pharmacy. “What surprised us was how consistently historical texts—from the Tang Dynasty onward—described effects that align closely with today’s understanding of hair biology.”
The researchers examined a wide range of evidence, including laboratory studies, clinical observations, and historical herbal literature. Together, these sources suggest that Polygonum multiflorum does more than simply slow hair loss—it may actively support healthier hair function.
One of the most striking findings is the herb’s potential role in hair regeneration. Rather than only delaying further thinning, Polygonum multiflorum appears to influence multiple growth factors involved in restarting and sustaining the hair cycle. This broader mode of action could give it an edge over treatments that focus on just one biological target.
The review notes that when properly processed—a critical step in traditional preparation, the herb shows a relatively favorable safety profile. This could make it more appealing to patients concerned about side effects such as sexual dysfunction or scalp irritation commonly linked to existing medications.
That said, the authors stress the need for more high-quality clinical trials to confirm effectiveness, establish safe dosing, and standardize preparation methods. Even so, the findings highlight how rigorous scientific study of traditional remedies can uncover new possibilities for treating common conditions like androgenetic alopecia.

As artificial intelligence becomes a go-to source for quick answers, a new University of Oxford-led study on AI chatbots and medical advice is raising serious concerns about how safe it is to rely on these tools for health guidance.
The research suggests that while AI chatbots can provide medical information, their advice is often inaccurate, inconsistent, and difficult for users to interpret, potentially putting people at risk—especially when dealing with symptoms that need urgent care.
The study involved 1,300 participants who were given realistic health scenarios, such as experiencing a severe headache or being a new mother feeling constantly exhausted. Participants were divided into two groups: one group used AI chatbots to understand their symptoms and decide next steps, while the other did not.
Researchers then assessed whether participants correctly identified what might be wrong and whether they made appropriate decisions, such as seeing a GP or visiting A&E.
The results were troubling. People who relied on AI frequently failed to identify the severity of their condition and were often unsure about when to seek professional medical help.
According to the researchers, one major issue is that people don’t always know what to ask. The study found that chatbot responses varied widely depending on how questions were phrased. Even small changes in wording could lead to completely different answers.
The AI often produced a mix of helpful and misleading information, leaving users to decide which advice mattered. Many participants struggled to distinguish between reliable guidance and unnecessary or confusing details.
As one of the study’s authors explained, when an AI lists multiple possible conditions, users are left guessing which one applies to them—precisely the moment where mistakes can happen.
Dr Rebecca Payne, lead medical practitioner on the study, warned that asking chatbots about symptoms could be “dangerous”, particularly when users delay seeking professional care based on AI responses.
Dr Adam Mahdi, the study’s senior author, noted that while AI can share medical facts, people often share information gradually and leave out key details—something chatbots struggle to manage effectively.
Experts also point out that chatbots are trained on existing medical data, which means they may repeat long-standing biases baked into healthcare systems. As one psychiatry expert put it, a chatbot is only as accurate as human clinicians—and humans are far from perfect.
That said, not everyone is pessimistic.
Digital health experts argue the technology is evolving. Health-specific versions of general AI chatbots have recently been released by major developers, and these could perform differently in future studies.
The consensus among experts is clear: AI in healthcare should focus on improvement, regulation, and guardrails, not replacement of doctors. Used responsibly, it may support healthcare—but without safeguards, it risks doing more harm than good.

This common pregnancy drug could be linked to cancer. Wes Streeting has been urged to launch a public inquiry into a miscarriage drug called Diethylstilbestrol, which, reports say has "ruined and devastated" the lives of countless women. On Monday, the Health Secretary Streeting met victims of the pregnancy drugs, which has been linked to cancer, early menopause and infertility.
Diethylstilbestrol, commonly known as DES, is a synthetic form of female hormone estrogen, which was prescribed to thousands of pregnant women from 1940 to 1970s.
The drug was used to prevent miscarriage, premature labor and complications of pregnancy. This was also used to suppress breast milk production, as an emergency contraception and to treat symptoms of menopause.
In 1971, Diethylstilbestrol (DES) was linked to a rare cancer of the cervix and vagina known as clear cell adenocarcinoma, prompting US regulators to advise that it should no longer be prescribed to pregnant women. Despite this, the drug continued to be given to expectant mothers across parts of Europe until 1978. DES has also since been associated with other cancers, including breast, pancreatic and cervical cancers, The Telegraph reported.
Campaign group DES Justice UK (DJUK) is now urging Health Secretary Wes Streeting to order a public inquiry and introduce an NHS screening programme to identify people who may have been exposed to the drug before birth.
Victims described DES as “one of the biggest pharmaceutical scandals this country has ever seen,” warning that “the impact of this terrible drug cannot be underestimated as it has ruined and devastated so many lives,” according to The Telegraph.
In November, Streeting acknowledged that the “state got it wrong” and issued an apology to those affected. He also advised anyone who believes they may have been exposed to DES to speak to their GP.
Susie Martin, 55, from Manchester, whose mother was prescribed DES during pregnancy, told The Telegraph she has undergone between 20 and 30 operations as a result of the drug’s effects.
“The impact of this terrible drug cannot be underestimated as it has ruined and devastated so many lives, including my own,” she said. “The physical and emotional pain has been unbearable. I live with a constant fear that I will need more surgery or develop cancer—and I am far from the only one.”
Calling DES a “silent scandal,” Martin said she hopes the government’s engagement will lead to concrete action. “While I welcome Mr Streeting meeting us, it will only matter if he commits to meaningful steps for victims of this shameful chapter in British medical history, including a screening programme and a full statutory public inquiry,” she added.
The Telegraph reported that compensation schemes have been set up for DES victims in the US and Netherlands, however, UK does not have one yet.
"There are harrowing accounts of harm caused by the historic use of Diethylstilbestrol (DES). Some women and their relatives are still suffering from the associated risks of this medicine which have been passed down a generation, and haven’t been supported. The Secretary of State has been looking seriously at this legacy issue and carefully considering what more the government can do to better support women and their families who have been impacted. NHS England has alerted all cancer alliances to this issue so that healthcare professionals are aware of the impacts of DES and the existing NHS screening guidance which sets out the arrangements for those who show signs and symptoms of exposure,” said a Department of Health and Social Care spokesman to The Telegraph.
