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.

Aging is a significant factor in memory loss and cognitive decline. Now, a team of US researchers has pinpointed a single protein that drives these changes in the brains of the elderly.
In aging mice, higher levels of protein FTL1 weakened connections between brain cells, leading to memory decline.
But when FTL1 was reduced, the brain began to recover. It also rebuilt lost connections and restored memory performance, according to the study, published in Nature Aging.
"It is truly a reversal of impairments," said Saul Villeda, Associate Director at the University of California - San Francisco's Bakar Aging Research Institute and senior author of the paper. "It's much more than merely delaying or preventing symptoms."
While the research was carried out in aging mice, it holds immense potential for human brain function.
In the study, the researchers tracked shifts in genes and proteins in the hippocampus of mice. The FTL1 protein appeared consistently different between young and old animals.
Compared to young mice, the older mice showed higher levels of FTL1. They also had fewer connections between neurons in the hippocampus and performed worse on cognitive tests.
Increasing FTL1 levels in young mice produced brain changes similar to those seen in older mice. The researchers found that this change occurs because of alterations in the way nerve cells produce FTL1 protein.
In older mice, the nerve cells that produced high amounts of FTL1 developed simplified structures, forming short, single extensions instead of the complex, branching networks seen in healthy cells.
Further experiments showed that in older mice, higher levels of the protein slowed cellular metabolism in the hippocampus -- the part of the brain responsible for learning and memory.
However, when researchers treated these cells with a compound that boosts metabolism, the negative effects were prevented.

Villeda believes these findings could pave the way for treatments that target FTL1 and counter its effects in the brain.
"We're seeing more opportunities to alleviate the worst consequences of old age," he said. "It's a hopeful time to be working on the biology of aging."

Cancer treatment has long been thought to be unsuccessful among people of advanced age, and older adults are often left out of clinical decisions.
While they may face more surgical complications, a new study proved that even people aged over 80 can still safely have surgery and be cured. It showed that the overall health of a patient matters more and that age must not be the only criterion to rule out surgery.
The study, published in The Lancet Regional Health – Americas, showed that surgery for lung cancer is safe in elderly patients aged 80 and above, especially when the cancer is in an early stage.
Researchers at the Icahn School of Medicine at Mount Sinai and the Mount Sinai Tisch Cancer Center in the US found that they can recover like young cancer patients as well as live longer like them.
“As our population ages, more patients over 80 are being diagnosed with early-stage lung cancer, yet they are often not considered for surgery,” said Raja M. Flores, Chair of the Department of Thoracic Surgery at Mount Sinai Health System.
“Our findings show that when patients are carefully selected based on their overall health, not just their age, they can tolerate surgery well and experience excellent long-term outcomes,” he added.
The study findings are based on a study of 884 patients with early-stage lung cancer, including 114 people who were age 80 or older.
The researchers examined surgical outcomes and quality of life in patients with early-stage non-small cell lung cancer, comparing those aged 80 and older with younger patients.
The results showed that older patients lived just as long as younger patients after surgery. While some older patients had more complications right after surgery, most patients in both groups felt better over time, and their quality of life improved within a year.
The study noted that early detection in older patients may be key. The researchers called for screening guidelines to include patients who are over 80 years old based on these findings.

Lung Cancer is one of the most common and serious types of cancer. It is also the leading cause of cancer-related deaths worldwide, with approximately 2.5 million new cases and 1.8 million deaths reported in 2022.
According to the American Cancer Society, lung cancer mainly occurs in older people. Most people diagnosed with lung cancer are 65 or older; a very small number of people diagnosed are younger than 45.
The average age of people when diagnosed is about 70.
It is also the leading cause of cancer death in the US, accounting for about 1 in 5 of all cancer deaths.
In many cases, there are no symptoms; however, one must look out for these:

Cancer is not just a problem of elderly people anymore. In India, there has been an increased number of cases where individuals under the age of 40 are diagnosed with various forms of cancer. Even if there are fewer cases of this medical condition among younger people, this fact does not change the fact that one-fifth of all cancer patients in India are younger than 40 years.
Breast cancer, colorectal cancer, head and neck cancer, as well as blood cancer, are some types of cancer that become more common at a younger age. Among the most alarming statistics, the incidence of colorectal cancer in people aged 30-40 should be mentioned. Moreover, the fact that breast cancer becomes evident nine years earlier in Indian women in comparison with Western women must also be noted.
There is a wide variety of factors that contribute to this problem. These are the following:
Early detection saves lives. Some warning signs to look out for are:
Not only does it take time to diagnose cancer cases in young patients due to low suspicions, but these cancers also create an additional burden on people during their prime earning period.
There needs to be a paradigm shift in our understanding of this problem. First of all, we have to understand that cancer affects patients irrespective of their age, and therefore, when you experience some symptoms of cancer, do visit a doctor to get your condition checked out.
The key is maintaining healthy practices like balanced nutrition, exercising, not smoking, and limiting consumption of alcohol.
