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.

Ever tried logging off social media platforms like Facebook and Instagram? For many, checking notifications, scrolling through feeds, and engaging with content has become second nature, often leading to an unnoticed addiction.
While digital dependence can significantly impact mental health, relationships, and overall well-being, most people don’t realize how much time they’re actually spending online.
To understand its effects, researchers at Stanford University in the US asked the 36,000 study participants to log off on weekends from their Facebook and Instagram accounts. The results showed that the people who stayed off felt measurably better.
Disconnecting from social media was seen as a powerful way to regain balance and focus in the increasingly connected world.
The study split participants into groups: about 275 were paid to deactivate their accounts for six weeks, while others logged off for just one week. Both groups showed improved emotional well-being compared to those who kept scrolling, but the effect was more pronounced for Facebook users who went longer without it.
Facebook users over 35 showed the biggest mood improvements, while among Instagram users, the 18-to-24 group benefited most.

Social Media And Mental Health
An increasing number of studies and the community at large are convinced that social media are detrimental to our mental health and general well-being.
According to a recent YouGov poll taken in the UK in January 2026, 37 percent of adults gave a general negative review of social media's impact on their mental health, more than twice the number of people who say otherwise.
Merely 14 percent of them admitted to receiving a positive effect from social media on their mental health.
The Pew Research Center survey, conducted in 2024, discloses that 45 percent of US teenagers think social media is damaging their sleep, and 40 percent believe it is hurting their productivity, which are both key factors of mental health.
In 2023, former US Surgeon General Vivek Murthy named social media as a major threat to the mental health of teens. He also released a social media advisory about social media and mental health.
The advisory indicates that frequent social media use could be associated with changes in parts of the brain related to emotions and learning. Additionally, it can affect impulse control, social behavior, emotional regulation, and sensitivity to social punishments and rewards.

In serious cases, social media can also contribute to self-harm or suicidal thoughts, especially among teens and children facing cyberbullying or trolling. Young people are particularly vulnerable to online pressures, negative comparisons, and feelings of rejection.
“Excessive social media exposure has been linked to anxiety, depression, sleep disruption, and, most importantly, difficulty with regulating attention and emotions. Algorithms intensify comparison, validation-seeking, and exposure to harmful content, which children lack the maturity to process,” Dr. Sachin Pradeep Baliga, Associate Consultant Mental Health & Behavioural Sciences, Fortis Healthcare, told HealthandMe.
According to mental health experts, moderation and mindfully controlled usage could be the key.

It is far more effective to come up with a plan that helps your interaction with social media platforms be healthier, such as limiting your time on social media platforms, avoiding harmful content, and pursuing real-world connections, rather than completely demonizing social media.

A team of researchers at the All India Institute of Medical Sciences (AIIMS) in Patna has made a significant breakthrough in understanding the link between heatstroke and fatalities.
The study published in the Medico-Legal Journal identified a specific brain center and vascular injury patterns that play a crucial role in heatstroke-related deaths.
The research team discovered that the anterior hypothalamus, which serves as the brain's primary temperature-regulating center, undergoes severe structural damage during heatstroke. This damage is found to be a key factor in the fatal outcomes associated with heatstroke.
“The study establishes that the anterior hypothalamus undergoes critical structural damage during heat stroke, making it a central driver of fatal outcomes. The injury in the hypothalamus can be used as definitive evidence in the forensic diagnosis of heat-stroke deaths,” said lead author Dr Ashok Kumar Rastogi, forensic expert, in a statement.
The finding can be a major step forward in the scientific basis for diagnosing heat stroke deaths through post-mortem examination, an area that has often posed challenges for autopsy surgeons in establishing a definitive cause of death, the researchers said.
It will also help address a long-standing medico-legal issue, particularly in the context of compensation, insurance claims, and death benefits for the families of victims.
The study was conducted by the Department of Forensic Medicine at AIIMS Patna in collaboration with the Department of Anatomy and Pathology.
The study was based on detailed post-mortem investigations of individuals exposed to extreme environmental conditions in the Patna region during 2024, including temperatures reaching 48 degrees Celsius, humidity levels up to 95 per cent, and prolonged heat exposure lasting five to eight hours, the Institute said.
The results also outlined a vascular injury pattern associated with fatal heat stroke, helping build a clearer pathological profile of the condition under extreme heat exposure.
The researchers noted that the findings could strengthen forensic investigations and support more scientifically grounded death certification in suspected cases.
Heatstroke is a medical emergency with a high case fatality rate. The body’s inability to regulate internal temperature and eliminate heat gain in such conditions increases the risk of heat exhaustion and heatstroke.
Speaking to HealthandMe, Dr. Naval Vikram, Professor, Department of Medicine, at the AII India Institute of Medical Sciences (AIIMS), explained how heat stroke affects people.
“The general features of a patient with heat stroke are: first, his or her body temperature will be very high. It will not be around normal levels like 104, 105, or 106—it will be significantly elevated. Second, the person may be delirious, confused, or even in a state of unconsciousness or coma. The breathing will also be labored. These are the features of heat stroke,” Dr Vikram said.
The most vulnerable category for heat-related problems is the extremes of age—the younger children and older adults. The expert noted that younger children may not be able to express their symptoms completely. They may not be able to tell you exactly what they are feeling.
At the other end, older adults often have multiple health issues—neurological conditions, diabetes, hypertension, and kidney problems.
How Can One Prevent?
Try to avoid exposure to extreme heat as much as possible.
Adequate hydration is key.
One must cover the head and upper body, use an umbrella, stay hydrated, and take breaks in between.
If you have to work in a hot environment for a couple of hours, take a break in a cooler or temperature-controlled environment for at least half an hour before resuming, rather than continuously working in the heat.

Recent photographs of former US President Donald Trump with the UK’s King Charles III have drawn attention after visible discoloration was observed on his left hand, raising fresh questions about his health.
While Trump’s right hand has appeared discolored in earlier public appearances—a concern previously downplayed by both the former president and the White House—the latest images show similar changes on his left hand as well.
“Trump's right hand has been in bad shape for a long time now, but this picture taken today shows discoloration on the back of his left hand," independent journalist Aaron Rupar wrote on social media platform X.
Speaking to HealthandMe, Dr. Amit Prakash Singh, Consultant - Internal Medicine at the CK Birla Hospital, Delhi, explained the possible underlying causes that can result in hand discoloration. He noted that the condition may be due to:
This appears as blue, purple, or black patches. It may occur due to minor trauma or sometimes even spontaneously. The use of blood thinners or antiplatelet agents like aspirin can increase the likelihood of bruising. With age, blood vessels become more fragile, making bruising more common.
Dr. Singh advised people "to be concerned if there is sudden swelling in one hand, severe pain or tightness, persistent blue or black discoloration, breathlessness, fever with redness and warmth, or numbness and weakness".
"A purple or blue patch often suggests bruising, blue fingers may indicate circulation or oxygen issues, puffy hands suggest fluid retention, and red, hot swelling points toward infection," the expert said.
However, there is no official medical update on the discoloration in Trump's left hand. Therefore, any claims remain speculative. But it is not the first time that various speculations have been going around about the health of Trump.

In an interview with The Wall Street Journal, in January this year, the US President informed that he takes aspirin doses more than his doctors recommend, and that is the reason for the bruising seen on his right hand. He has repeatedly said that his health is in "excellent" condition.
In the interview, he said, "They say aspirin is good for thinning out the blood, and I don't want thick blood pouring through my heart."
Trump, now 70, was diagnosed with chronic venous insufficiency, a condition that occurs when veins have trouble moving blood back to the heart. He also showed signs of bruising on his hand, which many attributed to frequent handshaking and to the use of aspirin.
Aspirin may still be considered for some people under 60 or 70 who have a higher risk of heart disease, but this decision should be made carefully. Factors like high blood pressure, high cholesterol, diabetes, smoking history, or a strong family history can influence whether aspirin makes sense for an individual.
