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.

Heart clips—also referred to as heart valve clips—are part of a minimally invasive medical procedure known as Transcatheter Edge-to-Edge Repair (TEER). Designed to repair leaking heart valves without open-heart surgery, this advanced treatment restores proper blood flow, relieves debilitating symptoms, and helps patients return to their daily lives.
The heart's valves rely on thin flaps of tissue called leaflets to regulate blood flow.
When a valve is leaking, the leaflets fail to close completely, leaving a gap. Blood leaks backward through this opening toward the lungs, increasing lung pressure and directly causing chronic breathlessness and fatigue.
During a Transcatheter Edge-to-Edge Repair, cardiologists repair the valve using a tiny clip delivered through the vascular system:
Once the clip brings the leaflets together, backward leakage stops immediately, allowing the entire volume of blood to pump forward as intended.
Because the procedure is catheter-based rather than open-chest, patient recovery is remarkably swift:

Frequent cannabis use may worsen epilepsy-related symptoms, new research. It discovered that raised that people with drug-resistant epilepsy who used cannabis often had more frequent convulsive seizures and sought advanced epilepsy care much sooner than non-users.
Published in Epilepsia, the study analysed health records of 64 adults with drug-resistant epilepsy. It found that frequent cannabis users reached an intensive epilepsy monitoring stage an average of five years after their first seizure, compared to 18 years reported among non-users.
The difference of 13 years is attention-worthy but it must be noted that the study shows an association, not proof that cannabis worsens epilepsy.
Researchers compared 22 people who used cannabis at least 20 days a month to 42 people who did not.
The frequent users reported to have a heavier burden of seizure, one of the symptoms of epilepsy. They had more than twice as many convulsive seizures per year than non-users.
About 91% of frequent cannabis users experienced convulsive seizures, compared to roughly half of the non-users.
Seizures involve stiffening and jerking of the body and loss of consciousness. They constitute medical emergency as they are associated with sudden death in epilepsy.

Epilepsy is considered drug-resistant when seizures continue despite appropriate treatment with two antiseizure medications.
People with drug-resistant epilepsy may need to visit specialised epilepsy centres, where doctors can monitor them and recommend changes in medication, surgery, or other treatment options. In this study, frequent cannabis users reached this stage much earlier.
They were also discharged from hospital after taking an average of 3.05 antiseizure medications, compared with 2.21 among non-users.

This was a retrospective study based on health records of a small sample size. There may be other differences between people who used cannabis often and those who did not that could affect the severity of the seizures.
However, researchers were able to establish the timing of cannabis use for 15 of the 22 users. All 15 had started using cannabis before their first seizure, making it less likely that they had simply begun using cannabis to cope with an already existing seizure disorder.
The researchers say larger studies can determine whether cannabis contributes to worsening seizures.
The association between cannabis and seizures is complicated as CBD (cannabidiol) is reported to have beneficial effect on severe epilepsy.
To understand the seeming contradiction, we must understand the distinction between cannabis and purified cannabidiol (CBD).
A purified form of CBD is an approved treatment for certain severe forms of epilepsy. CBD is different from THC, the psychoactive element responsible for the “high” associated with cannabis. Recreational cannabis products may contain high concentrations of THC.
According to the researchers, animal studies suggest CBD can suppress seizures, while THC may have the opposite effect.
Hence, evidence that a specific CBD-based medicine can help certain epilepsy syndromes cannot be used to conclude that recreational cannabis is an epilepsy treatment.
Researchers suggest that THC acts on receptors concentrated in brain regions involved in seizures, raising the possibility that cannabis could influence how brain circuits fire. But this is a hypothesis that needs further investigation.

A stroke changes the life of a person in an instant, making everyday activities like walking, talking, or even holding a cup difficult. But strokes do not always mean these challenges are permanent. Many people recover lost abilities and enhance their lives with timely treatment, proper rehabilitation and continued support.
A stroke occurs when blood stops flowing to the brain or a blood vessel in the brain bursts, cutting off oxygen to brain cells. It can cause weakness or paralysis, speech problems, poor balance, or memory issues, or trouble swallowing, depending on the part of the brain that is affected.
Patients who reach the hospital within a certain time may be eligible for clot-busting medications or clot removal procedures. These procedures restore blood flow, reduce brain damage and increase the likelihood of faster recovery.
Stroke care extends beyond emergency treatment. Rehabilitation begins within 24 hours after a stroke when the patient is medically stable. A team of specialists, including neurologists, physiotherapists, and speech therapists, works together to help the patient regain function, rebuild confidence and return to everyday activities as soon as possible.
When a stroke happens, muscles on one side of the body may become weak or paralysed, affecting the patient's strength, balance, coordination, posture, and walking.
Physiotherapy consists of a series of exercises, muscle training and mobility techniques that enhance mobility of the body and improve functional independence. Many patients can perform activities with greater ease with regular rehabilitation.

After a stroke, some patients have problems talking, speaking, swallowing, remembering or concentrating. Speech and language therapy are used to help with communication and safe swallowing, and cognitive rehabilitation is used to support memory, attention, reasoning and problem solving. These therapies assist patients in re-entering the workforce, social circles and independent living more smoothly.
Advances in rehabilitation have expanded the range of therapies available to support stroke recovery.
Techniques like robot-assisted rehabilitation, functional electrical stimulation (FES), virtual reality-based therapy, constraint-induced movement therapy, balance training systems and computer-assisted gait training complement conventional rehabilitation very well. These methods provide repetitive, targeted exercises that promote functional improvement in the brain and body.
After a stroke, some patients have muscle stiffness (spasticity), chronic pain or trouble walking or moving their hands. They are treated with medications, injections and continued rehabilitation therapy.
Recovery from a stroke is much better with proper rehabilitation. While some regain most of their abilities, others continue to need support, making patience and consistency just as important as medical help. The right care at the right time makes a big difference in rebuilding your life.
