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.

Signs That High Cortisol Is Stressing Your Body

Persistent Eye Twitches

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.

Skin Breakouts and Sensitivity

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.

Frequent Bloating and Digestive Issues

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.

Weight Fluctuations

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.

Unexplained Bruising

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.

Cold Symptoms That Won’t Go Away

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.

Vision Problems

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

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.

Tinnitus or Persistent Ringing in the Ears

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 Inflammation and Chronic Disease

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.

Long-term Consequences of Increased Cortisol

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.

Ways Managing Stress and Cortisol Levels

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.

Concerns around fertility and vaccines often surface when people plan a family, and the HPV vaccine is no exception. Many women and men worry that getting vaccinated today could affect their ability to conceive later in life. Medical experts, however, say this fear is misplaced. According to fertility specialists, there is no evidence linking the HPV vaccine to reduced fertility. In fact, the vaccine may play a quiet but important role in protecting reproductive health over the long term.

Does The HPV Vaccine Affect Fertility?

The short and clear answer is no. The HPV vaccine does not negatively affect fertility in women or men. Dr. Madhu Patil, Consultant and Fertility Specialist at Motherhood Fertility and IVF, Sarjapur, Bangalore, explains that there is no scientific proof showing the vaccine causes fertility problems of any kind.

She notes that concerns often arise from misinformation rather than medical data. Extensive research and global vaccination programmes have consistently shown that people who receive the HPV vaccine do not experience reduced chances of conceiving in the future.

How HPV Infection Can Threaten Future Fertility

While the vaccine itself does not harm fertility, an untreated HPV infection can. HPV is the leading cause of nearly all cervical cancer cases. As per Dr Patil, “treatment for cervical cancer often involves procedures such as cone biopsy or LEEP, which can weaken the cervix. In more advanced cases, radiation or chemotherapy may be required.”

These treatments can reduce a woman’s ability to conceive and, in some cases, make it difficult to carry a pregnancy to full term. By preventing HPV-related cancers in the first place, the vaccine helps preserve the reproductive system and lowers the risk of fertility-compromising treatments later in life.

Why The HPV Vaccine Supports Reproductive Health

Dr. Patil points out that the HPV vaccine should be viewed as a protective measure rather than a risk. By stopping high-risk HPV strains from causing cancer or precancerous changes, the vaccine helps maintain cervical health. A healthy cervix and reproductive system are key factors in natural conception and safe pregnancies.

In this way, the vaccine indirectly supports fertility by reducing the likelihood of medical interventions that could interfere with reproductive function.

When Should the HPV Vaccine Be Taken?

Health experts recommend starting HPV vaccination at ages 11 or 12. At this stage, the immune response is strongest, and the vaccine offers protection well before any potential exposure to the virus. Dr. Patil strongly encourages parents to consult a gynaecologist and consider timely vaccination for their children.

That said, adults who missed vaccination earlier can still benefit. Many women and men receive the vaccine later in life after discussing it with their doctor.

Why Men Should Also Get The HPV Vaccine

The HPV vaccine is not only for women. Dr. Patil stresses that men should also be vaccinated, as HPV can cause cancers and genital warts that affect sexual health. Vaccination in men also reduces transmission to partners, adding another layer of protection for couples planning a family.

By limiting the spread of HPV, vaccination helps safeguard the reproductive and sexual health of both partners.

There is no evidence that the HPV vaccine reduces fertility. On the contrary, it helps prevent cancers and medical treatments that can threaten the ability to conceive or carry a pregnancy. Experts advise speaking with a gynaecologist, understanding the benefits, and making an informed decision based on medical facts rather than fear.

A three-year-old girl was left partially blind after what first seemed like a routine ear infection was later diagnosed as a life-threatening brain tumour. As per Express UK, Chloe Kefford was rushed to A&E when she started experiencing car sickness and balance problems. Doctors initially diagnosed her with an ear infection and sent her home with antihistamines. But as Chloe’s condition worsened, her parents insisted on further testing, which revealed a tumour affecting her optic nerve.

Ear Infection Symptoms Masked A Life-Threatening Diagnosis

Chloe, from Formby, Merseyside, underwent open brain surgery and faced three-and-a-half years of treatment, including proton beam therapy last year, after experiencing two relapses. Proton beam therapy uses high-energy protons to precisely target the tumour, limiting damage to surrounding healthy tissue.

Open Brain Surgery And Years Of Intensive Treatment Followed

Now nine years old, Chloe has been honoured with a special award from Cancer Research UK for her bravery throughout her treatment. She received her initial care at St George’s Hospital in London and The Royal Marsden, before being transferred to Alder Hey in Liverpool.

Proton Beam Therapy Used After Cancer Relapsed Twice

Chloe’s mother, Nikki, 38, recalled that the family had been planning a move from Surrey to Merseyside before Chloe fell ill. As per Express UK, she said: “The house was already sold and we were planning our new life by the beach when Chloe became ill. Then we ended up moving and having to isolate for months. She relapsed not long after we moved and had more chemotherapy, then she rang the bell in April last year, but unfortunately, she relapsed again in July. So, we were supposed to be going on holiday to Disneyland in Paris and instead we went to Manchester for six weeks for Chloe to have proton beam therapy.”

Nikki added: “She is partially sighted now and has no peripheral vision; one eye is particularly badly affected. The main aim now is to preserve what eyesight she has left. We’re hopeful that the recent targeted treatment has got the cancer once and for all. She’s on steroids at the moment and is being monitored with three-monthly scans. She’s still in recovery and struggles with fatigue from the treatment, but we hope she’ll have a bit more energy soon. She’s our little ray of sunshine.”

Each year, around 400 children and young people in the North West are diagnosed with cancer. Advances in treatment and research are helping make therapies more effective and less harmful. Alder Hey Children’s Hospital in Liverpool is one of several centres across the UK taking part in pioneering clinical trials offering innovative new treatments.

In 2018, Cancer Research UK launched the Children’s Brain Tumour Centre of Excellence, supported by TK Maxx. The virtual centre brings together international experts in children’s brain tumour research to transform how treatments are developed. Every child nominated for a Star Award receives this recognition, which is endorsed by celebrities including JoJo Siwa and Pixie Lott.

Cancer Research UK spokesperson Jemma Humphreys said: “After everything Chloe’s been through, it’s been an absolute privilege to celebrate her incredible courage with a Star Award.”

People experiencing certain symptoms are being urged to stay at home as a highly contagious virus spreads quickly across England. Fresh figures from the UK Health Security Agency show a 47% rise in cases during the first two weeks of 2026. This sudden jump has led the agency to remind the public about basic hygiene steps that play a key role in limiting the spread. Data suggests that norovirus is affecting people aged 65 and above the most, and although overall activity remains within normal seasonal levels, there has been a noticeable increase in outbreaks in hospital settings.

The latest UKHSA surveillance update also points to falling levels of flu, COVID-19, and RSV in the opening week of the year. While all winter virus levels are currently where they would be expected for this time of year, people are being encouraged to continue following simple precautions to help keep infections on a downward path.

What Is Norovirus?

Norovirus Symptoms

Common symptoms of norovirus include:

• Nausea.
• Vomiting.
• Diarrhoea.
• Stomach pain.

You may also experience:

• Headache.
• Fever.
• Body aches.

Symptoms usually develop between 12 and 48 hours after exposure and typically last for one to three days.

Doctors Report New Symptoms Of Norovirus

Both flu and norovirus can behave unpredictably, with case numbers rising and falling throughout the season. This makes simple preventive steps especially important. For illnesses affecting the stomach or respiratory system, such as norovirus, regular handwashing remains one of the most effective measures.

Health experts stress that alcohol-based hand sanitisers do not work against norovirus. Washing hands thoroughly with soap and warm water, along with cleaning surfaces using bleach-based products, is far more effective in reducing the spread. Good ventilation indoors can also help limit the transmission of respiratory viruses like flu. Anyone who develops symptoms is advised to stay at home whenever possible.

If going out cannot be avoided, wearing a face covering may help, particularly when around people who are more vulnerable.

Amy Douglas, Lead Epidemiologist at the UKHSA, said, according to the Mirror: “We have seen a clear rise in norovirus cases in recent weeks, particularly among people aged 65 and over, alongside an increase in hospital outbreaks. Although levels are still within what we would normally expect, there are simple actions people can take to stop norovirus spreading further.

“Washing hands with soap and warm water and cleaning surfaces with bleach-based products are key steps. Alcohol gels do not kill norovirus, so they should not be relied on alone.

“If you have diarrhoea and vomiting, do not return to work, school, or nursery until 48 hours after symptoms have stopped, and avoid preparing food for others during this time. If you are unwell, please stay away from hospitals and care homes to protect those most at risk from infection.”
