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.

Itchy skin is something most of us deal with occasionally, and in many cases, it is harmless. Everyday triggers such as rough clothing, insect bites, or dry winter air can all leave the skin irritated. Itching is also commonly linked to skin conditions like eczema or psoriasis.

That said, an oncologist has pointed out that persistent itching can, in some cases, be linked to certain cancers. In a TikTok video, Dr Amit Garg, a cancer specialist based in California, explained that itching can appear as a symptom in four specific types of cancer. While itching alone is not usually a cause for concern, it may become more meaningful when it occurs alongside other symptoms that should be checked by a GP.

1. Hodgkin Lymphoma

Hodgkin lymphoma is a relatively rare cancer that affects lymphocytes, the white blood cells that help the body fight infection. Dr Garg explained that this cancer can cause “severe, widespread itching,” which often becomes worse at night. The NHS also lists itchy skin as a possible symptom, along with:

• A painless lump or swelling, usually in the neck, armpit, or groin, which is the most common sign
• Pain in the glands of the neck, armpit, or groin after drinking alcohol
• A high temperature
• Night sweats
• Shortness of breath
• Sudden, unexplained weight loss

The NHS advises seeing a GP if you notice any of these symptoms. Although they are common and do not always point to Hodgkin lymphoma, it is important to rule it out. Early diagnosis improves the chances of successful treatment, so symptoms should not be ignored.

2. Polycythemia Vera

Polycythemia vera is a rare, slow-developing blood cancer. According to the NHS, it is most often caused by a change in the JAK2 gene, which leads the bone marrow to produce too many red blood cells. An increased concentration of red blood cells is known as erythrocytosis, although having this condition does not automatically mean cancer.

One symptom of erythrocytosis can be itchy skin, particularly after bathing or showering. You should speak to a GP if symptoms persist. Other signs may include:

• Headaches
• Blurred vision
• Reddened skin, especially on the face, hands, and feet
• Tiredness
• High blood pressure
• Dizziness
• Discomfort in the abdomen
• Confusion
• Bleeding issues such as nosebleeds or bruising
• Gout, which can cause joint pain, stiffness, and swelling

3. Gallbladder And Pancreatic Cancer

Gallbladder cancer and pancreatic cancer often share similar symptoms. These can include a reduced appetite, unintentional weight loss, fever, nausea, and changes in bowel habits such as diarrhoea or constipation.

Dr Garg explained that both cancers can cause “intense itching,” which happens when bile salts build up under the skin. The NHS also lists itching as a symptom for both conditions, noting it may occur alongside darker urine, paler stools, and jaundice, which can cause yellowing of the skin or the whites of the eyes.

One key difference between the two cancers is the type of pain experienced. Gallbladder cancer may cause a dull ache on the right side of the abdomen, while pancreatic cancer more commonly causes pain in the upper abdomen and back, which can worsen after eating or when lying down.

In both cases, you should see a GP if symptoms last longer than two weeks or if you have lost weight without trying. You should call 111 if vomiting lasts more than two days, diarrhoea continues for more than seven days, or if your skin turns yellow.

4. Cutaneous T-cell Lymphoma

Cutaneous T-cell lymphoma is a form of skin lymphoma and a rare type of non-Hodgkin lymphoma. It begins in the T cells of the skin and often appears as flat, red patches that may be itchy.

In its early stages, these patches can resemble common skin conditions such as eczema or psoriasis. Seeing a GP is important if symptoms develop, as they can assess whether it is a common skin issue or something more serious.

Cancer Research UK states that around 150 people in the UK are diagnosed with cutaneous T-cell lymphoma each year, making it a rare cancer. As with many cancers, early diagnosis can play a key role in improving treatment outcomes.

A GP has advised women to make three simple health checks part of their monthly routine, saying the start of the month can act as a helpful prompt to stay consistent. The advice comes from Dr Carys Sonnenberg, an NHS women’s health GP and the founder of the Rowena Health Menopause Clinic. Speaking to her large audience on TikTok through her account @Rowenahealth_menopause, the doctor, author, and public speaker suggested setting aside the first day of every month for these routine checks.

Even if the date has already passed this month, she noted it can still serve as a timely nudge for those who have not yet done them, and a useful habit to follow going forward.

Three Health Checks Doctor Recommends

In her video, Dr Carys explained to viewers: “It’s the first of the month, so it’s a really good day to do your chest check, to do your vulva check, and also to examine any moles that you have on your body, not forgetting your head.” She added that becoming familiar with your own body is key. “When you’re checking yourself, it really helps to understand what’s normal for you. I’m Dr Carys Sonnenberg.

“I’m a GP and a menopause specialist. There is some excellent guidance online that shows you how to check your chest properly, what changes to be mindful of, and which symptoms should be discussed with your GP.

How To Do Health Checks Properly

“For the rest of your body, you’ll need a mirror. You might also want someone to help check areas you cannot easily see, such as your back, in case there are skin moles that look different or have changed. Don’t forget to part your hair and look at your scalp as well, in case there’s anything unusual that needs attention. I hope that’s helpful.”

Breast Changes To Watch For

Health experts stress the importance of staying alert to changes in your breasts or chest that could signal a problem. Making monthly checks a habit is a simple way to stay aware, while also remembering that some changes can occur naturally, such as during different phases of your menstrual cycle.

Possible signs of breast cancer can include:

• Skin changes like puckering or dimpling
• An unusual lump or swelling in the armpit or near the collarbone
• New lumps or areas of thickened tissue
• Fluid leaking from the nipple
• Crusting or a rash on or around the nipple
• A nipple that turns inward or changes direction
• A sudden change in breast size or shape
• Ongoing, unexplained pain in the breast, chest, or armpit

Secondary symptoms may include trouble sleeping, feeling generally unwell or sick, a loss of appetite, unexpected weight loss, and ongoing tiredness or low energy. While these signs do not always point to breast cancer, doctors advise contacting your GP if you notice anything unusual. Always speak to your GP if you have concerns about your health.

Earphones have slipped into almost every part of daily life. They power music, calls, podcasts, workouts, and long online meetings. What often goes unnoticed, however, is the steady rise of a silent and irreversible condition linked to their misuse: noise-induced hearing loss.

According to the World Health Organisation, more than one billion young people worldwide are at risk of hearing damage due to unsafe listening habits involving earphones and similar devices. Health experts say this is no longer a distant concern but a growing reality, with similar listening patterns being seen across India as well.

What Is Noise-Induced Hearing Loss?

Noise-induced hearing loss, or NIHL, occurs when loud sounds damage the delicate hair cells inside the inner ear. These hair cells play a critical role in transmitting sound signals to the brain. Once damaged, they do not recover or regenerate.

Dr Vinayak Kurle, Consultant ENT at Aster RV Hospital, Bangalore, explains that prolonged exposure to loud audio is one of the most common causes. “The inner ear has a limited number of hair cells. When they are exposed to excessive noise, especially over long periods, the damage can be permanent,” he says.

The generally accepted safe listening level is 85 decibels. Exposure to sound above this level for extended durations significantly increases the risk of hearing loss. Many personal audio devices can easily cross this threshold, especially at higher volume settings.

Early Warning Signs You Should Not Ignore

Hearing damage often develops gradually, which makes it easy to overlook early symptoms. Some of the first signs include:

• Ringing or buzzing in the ears
• A blocked, muffled, or distorted sense of hearing
• Difficulty understanding speech, particularly in noisy environments
• Ear discomfort after long listening sessions
• Increased sensitivity to everyday sounds

Dr Kurle notes that many people dismiss these signs as temporary fatigue. “Ignoring early symptoms delays diagnosis and allows the damage to progress,” he says.

Why Delayed Action Can Be Harmful

Untreated hearing loss affects far more than just hearing. Over time, it can contribute to social withdrawal, low mood, reduced concentration, and a decline in work performance. Studies have also linked hearing impairment to cognitive decline when left unaddressed.

What makes NIHL especially concerning is that the damage builds slowly. By the time people realise something is wrong, hearing loss is often already permanent.

How To Protect Your Hearing?

The good news is that noise-induced hearing loss is largely preventable with simple, consistent habits. Avoiding exposure to loud noise remains the most effective step. When loud environments cannot be avoided, protective options such as earplugs, earmuffs, or noise-filtering devices can reduce risk.

Noise-cancelling earphones can also help, as they reduce the need to raise volume in noisy surroundings. Following the WHO’s 60–60 rule is another practical safeguard. This means listening at no more than 60 percent volume for no longer than 60 minutes at a time.

Experts also advise limiting total daily earphone use, keeping volume below 80 decibels, taking regular listening breaks, and scheduling periodic hearing tests. At the first sign of symptoms such as ringing or muffled hearing, consulting an ENT specialist is crucial.

“Hearing loss does not happen overnight,” Dr Kurle says. “It develops quietly over time. Healthy listening habits today are the only way to protect hearing in the long run.”

Preserving hearing requires awareness, restraint, and timely action. In a world filled with constant sound, listening safely may be one of the most important health choices we make.
