Heart disease is often linked to high cholesterol, obesity, or lack of exercise. However, there is mounting evidence that suggests that mental health plays a crucial role in cardiovascular well-being. Stress, anxiety, and depression can silently strain the heart, increasing the risk of serious complications.

A recent study, published in Nature Human Behaviour, showed that loneliness has a significant impact on proteins present in a person's blood. For the study, researchers used data from more than 42,000 participants to explore whether the 9.3% who reported social isolation and 6.4% who reported loneliness had different levels of proteins in their blood compared with those who did not. The researchers then studied data that tracked the health of participants over an average 14-year period.

"We found around 90% of these proteins are linked to the risk of mortality," Dr Chun Shen, Fudan University in China, who is also the lead researcher said. "In addition, about 50% of the proteins were linked to cardiovascular disease, type 2 diabetes and stroke," he added.

Dr Shrey Kumar Srivastav, senior consultant at Sharda Hospital, said that subtle symptoms of heart disease, such as fatigue, shortness of breath, swelling in the lower legs, dizziness, and jaw pain, are often overlooked or attributed to stress and ageing. "Women, in particular, may experience atypical signs like extreme fatigue, indigestion, or upper abdominal pain instead of classic chest pain, leading to delayed diagnosis," he added.

Can Mental Health Issues Trigger Heart Diseases?

Chronic stress can trigger harmful cardiovascular effects, including elevated blood pressure, increased heart rate, and inflammation—key contributors to heart disease. Anxiety and depression further impact heart health by disrupting sleep patterns, raising stress hormone levels, and encouraging unhealthy habits like poor diet and inactivity.

Mental health issues like depression and anxiety have a profound impact on the heart. They don’t just affect emotions but can increase inflammation and put extra strain on the cardiovascular system, warns Dr Srivastav.

Certain risk factors, such as obesity and diabetes, disproportionately affect women, making them more vulnerable to heart failure with preserved ejection fraction (HFpEF). However, due to gender-specific symptom variations, heart disease in women often goes undiagnosed for longer.

Obesity is more prevalent in women than men and is a major risk factor for heart failure. Diabetes, too, has a greater impact on women’s heart health, yet diagnosis and treatment delays are common. Addressing this gap requires increasing awareness, training healthcare providers, and promoting early diagnostic tools,” explains Dr Srivastav.

How Can You Protect Your Heart?

A simple yet effective way to support heart health is by committing to a brisk 30-minute walk daily. Walking not only helps regulate blood pressure and manage weight but also improves circulation and reduces stress.

"Regular physical activity, paired with a heart-healthy diet rich in fruits, vegetables, whole grains, and lean proteins, significantly lowers cardiovascular risks," advises Dr Srivastav.

Heart disease can often go undetected until a major event occurs, making routine screenings essential.

- For women: Begin screenings around age 30 and continue with regular checkups.

- For men: Start screenings at age 35.

Health screenings, including blood pressure checks, cholesterol tests, and electrocardiograms (ECGs), are critical for early detection of silent heart conditions.

The World Cup is at the doorstep, and fans are excited to witness their favorite stars once again in their clash to get the golden trophy. It has been over 20 years since the World Cup returned to the US, though Canada and Mexico are also among the hosts. The fans are reaching America from all over the world. The players are also ready to make their mark on the largest scale of the sport.

Thus, it becomes crucial to keep the athletes fit and healthy. There is a huge team behind the scenes to treat and take care of your favorite stars, which requires strategy, planning, and most of all, accurate execution. On this backdrop comes a name that makes the difference known as the Pro Sports Doc, Riley J. Williams III, who is known to be an expert, and he will coordinate medical care during this demanding tournament.

The Pro Sports Doc, with his 20 years of experience, will be working and coordinating medical care in the New York / New Jersey area. In an interview with Muscle and Fitness, Riley J. Williams III put emphasis on players getting acclimatized and synchronizing their sleeping patterns with North America. He also mentioned creatine as a great health supplement. He also reveals that his team has readied the entire spectrum of possible medical issues that might occur while teams are in the market.

FIFA has also issued standard procedures to keep the players safe. Each Participating Member Association shall include at least one team medical doctor in its delegation, to be present in the technical area during all matches. It is a mandatory requirement that the team medical doctor of each Participating Member Association complete and successfully pass the “Concussion” and “Sudden Cardiac Arrest” modules of the FIFA Diploma in Football Medicine before the FIFA World Cup 26.

The team's medical doctor is responsible for the overall health of their team delegation and any clinical decision‑making in this regard, both on and off the field of play. Although the team doctors’ primary responsibility is to the players, their medical responsibility extends to all other members of the delegation. As such, all team doctors shall ensure that they have the appropriate registration and licence in their home country.

Each Participating Member Association shall ensure and confirm to FIFA that its players have undergone a cardiac screening, including personal and family history, clinical examination, and resting 12‑lead ECG, within the last 12 months and an echocardiography within the last 24 months before the start of the final competition of the FIFA World Cup 26. If specifically performed for the tournament, FIFA recommends that participating teams use the screening form developed by FIFA cardiology consultants.

More than 2,000 confirmed measles cases have been recorded in the United States so far this year, putting the country on track for its worst measles outbreak in decades.

The virus continues to spread in unvaccinated and under-vaccinated communities, including among infants who are too young to receive the vaccine, highlighting the growing impact of misinformation and declining vaccination rates.

Although measles was declared eliminated in the US in 2000 and past outbreaks were rapidly contained, vaccination coverage has fallen in recent years, particularly following the COVID-19 pandemic, increasing the risk of larger and more difficult-to-control outbreaks.

Health Experts have argued that the situation has been worsened by vaccine skepticism promoted by President Donald Trump and Health Secretary Robert F. Kennedy Jr.

Kennedy has repeatedly framed measles vaccination as a personal choice and has also promoted vitamin A as a treatment option during the outbreak, prompting a surge in public interest.

A June 2026 study published in the JAMA Network claimed that internet searches combining "vitamin A" and "measles" increased by 44 per cent on February 26, 2025, and reached peak popularity on March 22, 2025.

The study, led by Boston Children’s Hospital and University of California, also found that searches for "cod liver oil" and measles peaked at 52.6 per cent on March 5, 2025, following government statements in February advocating vitamin A as a treatment.

Earlier in 2025, Kennedy also falsely claimed that the MMR vaccine—which protects against measles, mumps, and rubella—causes encephalitis, or brain swelling, while also saying it "does stop the spread of the disease."

Excessive Vitamin A Use Led To Poisonings

In April 2025, America's Poison Centers (APC) reported a rise in the use of alternative measles prevention methods and warned about the risks associated with excessive consumption of vitamin A and cod liver oil, People.com reported.

"For patients with measles, particularly hospitalized children, vitamin A supplementation is recommended to help reduce the risk of severe complications," APC said in a statement.

According to APC, symptoms of vitamin A toxicity can include nausea, vomiting, stomach pain, headaches caused by increased intracranial pressure, bone pain, vision changes, and liver damage.

The organization reported 86 pediatric vitamin A exposure cases between January 1 and March 31, 2025—a 38.7 per cent increase compared with the same period in 2024. However, APC noted that there had been no increase in the severity of poisonings, with no major adverse effects reported in 2025.

According to the Mayo Clinic, vitamin A supplementation is recommended for children with measles who are at increased risk of vitamin A deficiency. Research suggests that supplementation may help reduce the risk of death and severe complications from the disease.

However, health experts continue to stress that the MMR vaccine remains the most effective method of preventing measles.

"If someone is infected with measles, then vitamin A can help mitigate some of the longer-term sequelae, but it does not prevent measles in an unvaccinated person," infectious disease epidemiologist Catherine Troisi told Houston Public Media.

"Moderate doses of vitamin A can be useful in treatment, but the better choice is to prevent measles from happening in the first place through vaccination."

The much-awaited 2026 FIFA World Cup is set to begin tonight. The tournament will be hosted by the United States, Canada, and Mexico across 16 cities in the three countries.

The 39-day event kicks off in Mexico on Thursday amid ongoing health outbreaks such as measles, Ebola, and hantavirus.

More than 750,000 soccer fans are expected to travel from over 100 countries to witness 104 matches. The influx of visitors will crowd public transportation, restaurants, and other public spaces, increasing the risk of exposure to infectious diseases, heat-related illnesses, and injuries.

Ahead of the mass gatherings, the Pan American Health Organization (PAHO) has issued new public health recommendations for travelers.

"The celebration happens both inside and outside the stadiums, but to fully enjoy it, it's important to take care of yourself and stay informed," PAHO said.

FIFA World Cup: US Experts To Monitor Wastewater

A public health team based in Washington, D.C., plans to monitor wastewater and internet activity to detect and track infectious diseases should they emerge in any of the US or Canadian cities hosting World Cup matches, players, and millions of spectators, Reuters reported.

Detecting disease-causing microorganisms in wastewater can provide an early warning of emerging outbreaks, giving health officials time to alert clinicians to watch for symptoms that might otherwise be misdiagnosed and to encourage the public to take preventive measures.

FIFA World Cup: Heat A Major Health Risk

Beyond infectious diseases, heat is expected to be a major concern during the FIFA World Cup. Host cities such as Houston, Miami, Mexico City and Los Angeles can experience extreme temperatures in June and July, making it dangerous for fans standing outdoors in large crowds for extended periods.

Writing in Forbes, Jesse Pines, an integrative medicine physician at Eterna Integrative and a Clinical Professor at George Washington University (GW), explained that heat exhaustion occurs when the body overheats and loses vital fluids and salts through sweating.

"Warning signs include dizziness, a rapid but weak pulse and cool, clammy skin. Left untreated, it can escalate quickly into heat stroke — a life-threatening emergency that can kill or cause permanent brain damage. Core body temperature above 104 degrees F, confusion and cessation of sweating are the hallmarks," he said.

Pines noted that alcohol can significantly increase the risk of heat-related illness. To reduce the risk, he recommends eating a full meal before drinking, choosing water over alcoholic beverages and keeping electrolyte drinks on hand.

Who Is Most at Risk?

The expert said certain groups may face a higher risk during mass gatherings in summer heat, including:

• People aged 65 and older
• Individuals with chronic conditions such as heart disease, diabetes, COPD or kidney disease
• People who are immunocompromised
• Pregnant fans
