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.

Learning a second or even a third language may do more than expand your communication skills. According to a new study presented at the Federation of European Neuroscience Societies (FENS) Forum 2026 in Barcelona, learning a new language could also help keep your brain younger as you age.

The findings of the study say that people who speak multiple languages have brains that appear biologically younger than those who speak only one language. The research added to the growing evidence that multilingualism has a beneficial effect on healthy cognitive ageing.

About The Study

To investigate how language affects the ageing brain, researchers analysed brain activity in adults living in Spain's multilingual Basque region.

They used magnetoencephalography (MEG), a non-invasive brain imaging technique that records the brain's electrical activity, along with artificial intelligence (AI) to ascertain each participant's brain age.

Rather than relying on a person's actual age, the AI model assessed how well different regions of the brain communicated with one another, a key marker that normally weakens with age.

Researchers first trained the AI using brain scans from 728 adults with varying language abilities before validating the findings in an independent group of 144 participants.

The results revealed an association between multilingualism and a younger-looking brain. Compared with people who spoke only one language, bilingual participants had brains that appeared around six years younger. Those who spoke three languages had brains that looked approximately seven years younger, while participants fluent in four languages had brains that appeared up to 13 years younger.

Researcher Lucia Amoruso, deputy scientific director at the Basque Center on Cognition, Brain and Language in San Sebastián, Spain, said, “In simple terms, people who spoke more languages tended to have brains that looked younger than expected for their chronological age.”

The researchers also found that language proficiency mattered. People who learned additional languages earlier in life and became more fluent showed even greater differences in brain age.

Is Multilingualism The Key To Keep Your Brain Younger?

Scientists believe speaking multiple languages provides the brain with a constant mental workout. Regularly switching between languages requires attention, memory, problem-solving and cognitive control, all of which strengthen the neural networks involved in thinking and decision-making.

This exercise may help maintain stronger communication between brain regions, increasing the brain's resilience against age-related decline.

While the team considered factors like age, sex, and education, multilingual individuals may also be more likely to engage in other habits that are beneficial for the brain.

Although the findings are encouraging, the researchers say that the study does not prove that learning another language directly slows brain ageing or prevents dementia. Experts say further long-term studies are needed to determine whether multilingualism can reduce the risk of neurodegenerative diseases such as Alzheimer's disease.

Despite the need for more research, scientists say the findings offer another compelling reason to learn a new language. Whether through formal classes, language-learning apps or everyday conversations, developing language skills could provide meaningful mental stimulation throughout life.

Completing cancer treatment is often imagined as the moment life returns to normal. The final chemotherapy session ends, follow-up scans show encouraging results, and the long-awaited words, “You’re in remission,” bring immense relief. Family and friends celebrate the milestone, expecting life to pick up where it left off.

Yet for many survivors, the end of treatment marks the beginning of a different journey. The hospital visits may become less frequent, but new questions often take their place. Will energy levels ever return? Is it normal to still feel anxious before every check-up? How does one rebuild a life that has been profoundly changed by illness?

Life After Cancer

Life after cancer is not simply about surviving; it is about learning to live well again. This phase is an opportunity to focus not only on physical recovery but also on emotional healing, meaningful relationships, and rediscovering a sense of purpose. Survivorship is not defined by the absence of disease alone; it is measured by the quality of life that follows.

During treatment, every decision revolves around cancer. Appointments, medications, scans, and side effects dominate daily life. Once treatment ends, the focus gradually shifts from fighting the disease to rebuilding health and well-being. This transition, often referred to as survivorship care, is about moving from crisis management to long-term wellness.

The goal is no longer simply to eliminate cancer cells, but to create a life that feels fulfilling and meaningful. Survivors are encouraged to focus on three things treatment itself cannot provide: strength, joy, and a renewed sense of control.

Quality of life after cancer extends far beyond follow-up scans and medical reports. It encompasses physical, emotional, social, and practical well-being. Paying attention to each of these areas can help survivors thrive rather than merely cope.

Physical Recovery After Cancer Treatment

Physically, the body often needs time to recover from the effects of chemotherapy, surgery, radiation, or hormone therapy. Fatigue, reduced stamina, neuropathy, weight changes, and muscle loss are common challenges. Regular movement plays a critical role in recovery.

Experts recommend at least 150 minutes of moderate exercise each week, along with two sessions of strength training to rebuild muscle and improve energy levels. For survivors experiencing lymphedema, pelvic floor concerns, or mobility limitations, working with a physiotherapist can provide targeted support. A balanced diet rich in protein also helps restore strength and independence.

Emotional Recovery Post Cancer Treatment

Emotional recovery deserves equal attention. Fear of recurrence, anxiety before follow-up scans, survivor's guilt, and grief for the life that existed before diagnosis are all common experiences.

These feelings are not symptoms of weakness; they are natural responses to a life-changing event. Seeking support from a psycho-oncologist, counsellor, or support group can significantly improve emotional well-being. Even simple practices such as mindfulness, journaling, or spending a few quiet minutes each day focusing on the present moment can help reduce stress and build resilience.

Cancer's Impact On Relationships And Financial Pressures

Cancer can also reshape relationships. Some friendships may change, while family members and partners may continue adjusting to roles they adopted during treatment.

Open conversations about needs, limitations, and expectations can help strengthen these relationships. Reconnecting with supportive people, participating in survivor communities, or mentoring newly diagnosed patients can create a sense of belonging and purpose. Healing is often easier when it happens in the company of others.

Practical concerns can persist long after treatment ends. Financial pressures, career interruptions, insurance challenges, and concerns about returning to work can affect overall well-being. Seeking guidance from social workers, financial counsellors, or patient support organizations can help survivors navigate these issues. In India, government initiatives such as Ayushman Bharat, state-level healthcare schemes, and various non-governmental organizations may offer valuable assistance.

Challenges Of Survivors

One of the greatest challenges survivors face is the expectation of returning to the person they were before cancer. However, recovery is not about going back; it is about moving forward. A new normal often emerges, the one shaped by deeper self-awareness, healthier boundaries, and a greater appreciation for everyday moments.

Many long-term survivors describe experiencing what experts call post-traumatic growth. They report stronger relationships, clearer priorities, and a renewed sense of purpose. They become more intentional about how they spend their time and energy, recognizing that health and meaningful experiences deserve as much attention as professional achievements.

The first year after treatment is a time of adjustment. Establishing healthy routines, gradually resuming work and hobbies, staying consistent with follow-up appointments, and setting goals unrelated to cancer can help restore confidence. Whether it is taking a short trip, learning a new skill, planting a garden, or simply enjoying time with loved ones, these experiences remind survivors that life extends beyond medical milestones.

Risk of New Symptoms

At the same time, wellness does not mean ignoring new symptoms. Persistent pain, unexplained weight loss, unusual bleeding, ongoing fatigue, or symptoms of anxiety and depression that last more than two weeks should be discussed with a healthcare provider. Survivorship care is an essential part of recovery, and seeking help when needed is a sign of self-care, not concern.

Cancer may have changed the course of life, but it does not define its future. The chapter after treatment may look different from the one that came before, but it can still be rich with meaning, connection, and hope.

The treatment phase was about fighting to survive. The next phase is about discovering what makes life meaningful again. It is about protecting quality of life with the same determination that carried survivors through treatment—because surviving cancer is not only about living longer, but about living well.

Millions of people around the world undergo blood tests every year to measure LDL, commonly known as "bad" cholesterol. But researchers now suggest that this standard test may not always provide the most accurate picture of heart disease risk.

A new study from Northwestern Medicine found that a blood test measuring apolipoprotein B (ApoB) may be better than LDL cholesterol testing for identifying people who need more intensive treatment to reduce their risk of heart attacks and strokes.

The researchers also found that using ApoB to guide treatment decisions could prevent more cardiovascular events while remaining cost-effective for healthcare systems. The findings were published in the journal JAMA.

"We found that ApoB testing to intensify cholesterol-lowering medication would prevent more heart attacks and strokes than current practice, and that these health benefits were achieved at a cost that represents good value for US healthcare payers," said study lead author Ciaran Kohli-Lynch, Assistant Professor of Preventive Medicine in the Division of Epidemiology at Northwestern University Feinberg School of Medicine.

ApoB vs LDL: What's the Difference?

Doctors have traditionally relied on LDL ("bad") cholesterol and non-HDL cholesterol levels to assess heart disease risk and decide when patients should begin or intensify cholesterol-lowering treatment. While these tests provide useful information, researchers say they do not tell the whole story.

The difference lies in what the two tests measure:

• LDL cholesterol test: Measures the amount of LDL cholesterol in the blood.
• ApoB test: Measures the number of cholesterol-carrying particles—including LDL and other potentially harmful particles—that can enter artery walls and contribute to plaque buildup.

"Research strongly shows that apolipoprotein B (ApoB) is better at identifying who is at risk because it counts the total number of harmful particles in the blood," Kohli-Lynch said.

According to the researchers, the number of harmful particles may provide a more accurate measure of cardiovascular risk than LDL cholesterol levels alone.

What Is ApoB?

In a post on X, Dr. Sudhir, Senior Consultant Neurologist at the Institute of Neurosciences, Apollo Hospitals, Hyderabad, explained that ApoB is a protein found on potentially harmful cholesterol-carrying particles such as LDL and VLDL (very low-density lipoprotein).

"Think of ApoB as a count of the particles capable of entering artery walls and causing plaque. One ApoB is equal to one potentially harmful particle," he said.

Dr. Sudhir explained that two people can have the same LDL cholesterol level but very different numbers of cholesterol-carrying particles. The person with more particles will usually have a higher ApoB level and, potentially, a greater risk of cardiovascular disease.

He added that ApoB often provides a more accurate assessment of heart disease risk than LDL cholesterol alone.

Despite growing evidence supporting ApoB, the test is still not widely used in routine clinical practice because it generally requires an additional blood test beyond the standard cholesterol panel, increasing both cost and inconvenience.

"Our study asked: Is it worth spending extra money to use ApoB instead of LDL to guide treatment intensification?" Kohli-Lynch said.

Dr. Sudhir suggested that ApoB testing should be considered for:

• people with diabetes,
• prediabetes,
• metabolic syndrome,
• obesity,
• elevated triglycerides,
• strong family history of heart disease.

New Cholesterol Guidelines

Earlier this year, the American Heart Association and 10 other medical organisations released updated guidelines recommending that many people begin cholesterol-lowering therapy at younger ages.

"This means it is increasingly important to accurately identify who would benefit most from intensive treatment," Kohli-Lynch said.

The updated guidelines also recommend measuring ApoB, particularly in people with high triglycerides, diabetes or in situations where LDL cholesterol levels may underestimate the number of harmful cholesterol-carrying particles.
