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.

In early January, the U.S. Centers for Disease Control and Prevention (CDC) made one of the most significant changes to childhood vaccination policy in decades. Routine vaccination is no longer universally recommended for six diseases, including rotavirus, influenza, meningococcal disease and hepatitis A. The move follows a directive from President Donald Trump’s administration to reassess vaccine schedules and align them with what officials called “international consensus.”
Supporters of the change describe it as a step toward informed consent and transparency. Many public health experts see it very differently. They argue that the science behind the decision is selective, the process breaks with long-standing norms, and the consequences may only become clear years later.
So are these vaccines actually necessary, and is removing them from compulsory recommendation a reasonable move? Health and Me ran a fact check to see whether the four vaccines removed from the CDC universal guidelines would actually be a "better thing", as the Health Secretary and long time vaccine critic Robert F Kennedy Jr says.
Until recently, the CDC recommended routine childhood vaccination against 17 diseases. That number has now dropped to 11. Vaccines for rotavirus, influenza, meningococcal disease, hepatitis A, hepatitis B and COVID-19 are no longer universally recommended for all children. Instead, they fall under shared clinical decision-making, meaning parents can still opt for them after discussion with a healthcare provider.
Importantly, this does not mean the vaccines are banned or unavailable. Insurance coverage remains largely unchanged for now, and vaccines remain recommended for children at higher risk.
The larger concern raised by experts is not access, but messaging. Universal recommendations have historically been one of the strongest drivers of vaccine uptake.

Traditionally, changes to the U.S. vaccine schedule go through the CDC’s Advisory Committee on Immunization Practices, a panel of independent experts who review evidence publicly over months. This time, that process was bypassed.
Instead, the decision relied on a 33-page internal assessment prepared by two political appointees. Several experts criticized both the lack of transparency and the narrow interpretation of evidence.
Dr. Paul Offit, a pediatrician and vaccine expert at Children’s Hospital of Philadelphia, described the process as federal officials making sweeping decisions behind closed doors, without public input or broad expert review.
Rotavirus causes severe diarrhea and vomiting in infants and young children, often leading to dehydration. Before routine vaccination began in 2006, an estimated 55,000 to 70,000 U.S. children were hospitalized each year due to rotavirus.
The administration justified dropping the universal recommendation by emphasizing low mortality rates. However, CDC researchers previously estimated 20 to 60 deaths annually in the pre-vaccine era. Experts say focusing narrowly on death counts ignores the very real suffering and healthcare burden the virus caused.
Offit, who helped develop one of the vaccines, noted that most pediatric residents today have never seen a child hospitalized with severe rotavirus dehydration. That absence, he argues, is proof of success, not irrelevance.
Meningococcal disease is uncommon, but when it strikes, it can be deadly within hours. Even with treatment, about 15 percent of patients die, and up to 20 percent suffer permanent complications such as amputations or hearing loss.
The administration cited low incidence and World Health Organization thresholds to justify removing the universal recommendation. But experts counter that low incidence is precisely what vaccination programs aim to achieve.
Dr. David Stephens of Emory University pointed out that most high-income countries still recommend meningococcal vaccines, even with similarly low disease rates. He also warned that recent U.S. data show a resurgence, with 2024 recording the highest number of cases in over a decade.
Modeling studies suggest that U.S. vaccination programs have already prevented hundreds of cases and dozens of deaths. Removing universal recommendations, experts warn, risks reversing those gains.
Annual flu vaccination for children has been recommended since 2008, based on evidence that children both suffer from influenza and play a major role in spreading it.
The administration argued that randomized controlled trials have not proven flu vaccines reduce hospitalizations or deaths in children. What it did not emphasize is that such trials are not designed to detect rare outcomes like death.
Dr. Mark Loeb of McMaster University explained that proving mortality benefits would require trials involving millions of children, which is not feasible. Instead, real-world observational studies are used.
Those studies consistently show that flu vaccination reduces hospitalizations in children. A 2024 review in the New England Journal of Medicine estimated a 67 percent reduction in pediatric hospital admissions. Experts say dismissing this evidence reflects a misunderstanding of how vaccine effectiveness is measured.

Hepatitis A rarely causes severe illness in young children, which is precisely why childhood vaccination works. Children often spread the virus silently to adults, who face much higher risks of liver failure and death.
Dr. Noele Nelson, a former CDC epidemiologist, explained that vaccinating children interrupts this transmission chain and provides lifelong immunity. She warned that reducing childhood vaccination could recreate the conditions that once fueled adult outbreaks.
Claims that hepatitis A vaccines lack adequate safety data were also disputed. Clinical trials and decades of post-licensure monitoring have found no unexpected safety concerns, according to Nelson and other experts.
Public health experts broadly agree that these vaccines are not perfect and that honest discussions about risks and benefits matter. Where they strongly disagree is the idea that low disease rates or ethical limits on trial design justify weakening universal recommendations.
Low incidence, experts emphasize, is not a reason to stop vaccinating. It is evidence that vaccination works.
Whether the consequences of this policy shift emerge in five years or ten, many experts fear the costs will be paid quietly, through preventable hospitalizations, outbreaks and deaths that no longer make headlines but never needed to happen in the first place.

A GP has shared an urgent alert about a clearly visible cancer symptom that many women may be brushing aside. The doctor stressed that this particular sign needs to be checked without delay. Ahead of Cervical Cancer Prevention Week, beginning January 19, as per Mirror, Dr Rupa Parmar outlined key warning signs of the disease and cautioned that one in three women are skipping their routine cervical screening appointments.
She also highlighted that some of the most common symptoms are often dismissed. One such sign is weight loss, which many women may wrongly link to cutting back after festive overindulgence or returning to a normal routine in January.
Dr Parmar, a GP and Medical Director at Midland Health, explained: “Cancer cells interfere with the body’s ability to properly absorb fats, proteins and carbohydrates from food. As a result, calories are burned more quickly, leading to weight loss. Unexplained weight loss is often the most obvious sign of cancer and should always be checked straight away.” She added that sudden weight loss is not exclusive to cervical cancer and is recognised as a general warning sign across several types of cancer.
Cancer Research UK also notes that weight loss is common among people with cancer and can be one of the first reasons someone seeks medical advice. The charity points out that lung cancer and cancers of the upper digestive system are among those most often linked to weight loss.
Dr Parmar also highlighted other possible signs of cervical cancer.
Pain during intercourse can be caused by issues such as vaginal dryness, infections or skin conditions, Dr Parmar said. However, if pain is new and wasn’t present before, it could be linked to cervical cancer, as a growing tumour may begin to affect nearby tissues.
Experiencing three or more urinary tract infections within a year could indicate an underlying problem, including cervical cancer. Dr Parmar clarified that UTIs do not cause cancer, but repeated infections may occur if a tumour has advanced and is pressing on or blocking the urinary tract.
Ongoing and severe pain in the lower back or pelvic area with no clear explanation can be another warning sign, particularly when combined with other symptoms. As cervical cancer advances, this pain may intensify and can worsen during sex, urination or bowel movements.
Bleeding that is unusual for you should never be ignored. This includes bleeding during or after sex, spotting between periods, bleeding after menopause, heavier-than-normal periods, or cycles that last longer than usual. These changes can signal that something may be wrong.
Changes in vaginal discharge can also point to problems with the cervix. An increase in discharge, an unusual smell, changes in colour, or the presence of blood may occur once cancer has begun to affect nearby tissues.
If you notice any of these symptoms, it’s important to speak to a doctor as soon as possible.

Dietary supplements are already part of many people’s daily habits, especially at the start of the year when health goals are front of mind. What many may not realise is that there is one supplement the Government says everyone should be taking through the colder months. Health guidance recommends a small daily dose of vitamin D for everyone in the UK from around October to late March, as sunlight levels are too low for the body to produce enough on its own. Vitamin D supplements are easy to find and come in several forms, including tablets, capsules, gummies and liquid drops. Here is a simple breakdown of what vitamin D is and why it matters.
Vitamin D is an essential nutrient that helps control calcium and phosphate levels in the body. These minerals work together to support healthy bones, teeth and muscles.
When vitamin D levels are too low, children can develop rickets, a condition that causes bones to become soft and weak. In adults, deficiency may lead to osteomalacia, which can result in bone pain, muscle weakness and a higher risk of fractures.
UK health advice states that everyone should take a daily supplement containing 10 micrograms, or 400 international units, of vitamin D during autumn and winter.
This amount is considered sufficient to maintain general wellbeing, particularly bone and muscle health, at a time of year when sunlight alone is not enough for vitamin D production.
Official guidance explains: “This advice is particularly important for people who have little exposure to sunlight during spring and summer, including those living in residential or nursing care homes, people in prisons, and individuals who regularly wear clothing that covers most of their skin when outdoors.
“These groups are at greater risk of vitamin D deficiency. People with darker skin tones, such as those from African, African-Caribbean or South Asian backgrounds, may also struggle to get enough vitamin D from sunlight alone.
“All of these groups are advised to take a vitamin D supplement throughout the year, in line with standard government dietary guidance.”
A scheme that once allowed eligible people to apply for free vitamin D supplements was available previously, but this programme ended in 2021.
Between late March or early April and the end of September, most people can produce enough vitamin D naturally through sun exposure. The body creates vitamin D when UV-B rays from sunlight reach the skin.
Vitamin D is also present in certain foods, including oily fish, red meat, egg yolks, and fortified products such as some spreads and breakfast cereals.
Supplements can be bought easily from pharmacies and supermarkets, with some costing as little as 2p per day. Vitamin D3 is generally the preferred form.
Yes. While sunlight does not cause vitamin D overdose, taking excessive supplements over a long period can lead to a build-up of calcium in the body. This can weaken bones and cause damage to the kidneys and heart.
For most people, a daily intake of 10 micrograms is sufficient. NHS advice states that adults should not take more than 100 micrograms, or 4,000IU, per day, as higher amounts may be harmful.
If a doctor has advised a different dosage based on your individual health needs, it is important to follow their guidance.
