Irregular Sleep, Drinking Caffeine After 3PM Could Raise Your Risk Of Heart Attack And Stroke

I’ve always struggled with inconsistent sleep, staying up late and waking up at different times each day. My love for coffee was also on an all-time high with trying all the season specials. But it is only recently, I learned how this irregular sleep pattern and caffeine could increase my risk of heart attack and stroke. Now, I’m prioritizing a consistent sleep schedule and cutting out caffeine after 3 PM to protect my heart.

A new, shocking study shows that irregular sleep patterns can greatly increase the risk of heart attack and stroke. But that's not all: the timing of your caffeine intake could also play a critical role in your cardiovascular health. If you are struggling with inconsistent sleep patterns and regularly sipping on caffeinated beverages late in the day, you may be unknowingly putting yourself at risk for serious heart-related issues.

For most people, sleep is something of a given and we often only consider ourselves as long as we get our required seven to nine hours. However, according to a recent study conducted by researchers at the Children's Hospital of Eastern Ontario, it may not be that long after all. The study, which included more than 72,000 participants, found that people with irregular sleep patterns—those who fall asleep and wake up at vastly different times each day—face a 26% higher risk of experiencing a heart attack or stroke. This increased risk persisted even for those who managed to get enough sleep. The study followed up participants for eight years to track heart events such as heart attacks, strokes, and heart failure. The conclusions were clear: irregular sleep, even if it's sufficient in duration, is a major cardiovascular risk factor.

The researchers found that those whose sleep patterns were highly irregular had a significantly greater chance of life-threatening heart issues. The more erratic your sleep schedule, the greater the risk, regardless of how many hours you sleep. In fact, people with irregular sleep schedules showed worse cardiovascular health outcomes, including higher rates of high blood pressure, elevated stress hormones, and poor blood sugar and cholesterol management.

Senior scientist Dr. Jean-Philippe Chaput said "sleep regularity may be more relevant than sufficient sleep duration in modulating MACE [major adverse cardiovascular event] risk." In the study, it shows that our bodies are comfortable with consistency, and a varied sleep schedule may interfere with other processes that keep us healthy, especially the heart.

Is it Caffeine After 3 PM Causing Sleeplessness?

Another daily habit that may be putting your heart at risk is caffeine consumption after 3 PM. According to Dr. Chaput, the experts emphasize the need for a healthy sleep schedule and avoiding caffeine late in the day. Caffeine can stay in your blood for up to eight hours, and its consumption later in the afternoon can disrupt your sleep cycle.

Consistent, good-quality sleep is necessary for maintaining healthy cardiovascular function, and the disruption of this by late-day caffeine intake exacerbates the risks posed by irregular sleep. When you drink coffee, tea, or other caffeinated beverages too late, the stimulant effect on your nervous system makes it harder to fall asleep at a regular time. This can lead to inconsistent sleep patterns, which, as we have seen, can be harmful to heart health.

Dr Chaput insists that humans need to adopt practices that contribute to regularized sleep habits. This can be attained by establishing a proper sleeping and waking schedule, eliminating afternoon intake of stimulants such as caffeine, and making your body clock coincide with the lifestyle one leads.

How Does Poor Sleep Affect Heart Health?

According to the experts, the disturbance due to irregular sleep patterns impacts more than one physiological process involved in the maintenance of the healthy heart. For example, poor sleep can be associated with increased inflammation of the body, weakened immunity, and altered regulation of blood sugar and cholesterol, all of which contribute to increased blood pressure and weakening endothelial function, both associated with an increased risk for cardiovascular diseases. Sleep also plays a very important role in regulating stress hormones. Poor or disturbed sleep results in increased levels of cortisol, the stress hormone, which increases blood pressure and can have negative impacts on cardiovascular health over time.

Scientists hypothesize that these disturbances trigger a series of negative effects that enhance the risk of developing chronic heart conditions, including hypertension, atherosclerosis, or even heart failure.

Tips to Protect Your Heart and Improve Your Sleep

In order to protect your heart, experts recommend several proactive measures to improve your sleep patterns and lifestyle. First, maintain a regular sleep schedule whereby you go to bed and wake up at the same time every day, including weekends. Consistency will keep your body's internal clock in check.

Along with regulating your sleep, paying attention to your caffeine habits is just as important. To reduce your risk of heart disease and stroke, experts suggest avoiding caffeine after 3 PM. If you’re sensitive to caffeine, this rule becomes even more critical.

In addition, the introduction of stress-reducing activities like yoga or mindfulness can also be beneficial to lower cortisol levels, and therefore both sleep and heart health can improve. A diet rich in antioxidants, healthy fats, and low on processed sugars also helps maintain cholesterol levels and reduce inflammation.

Does Your Sleep Environment Also Has A Role To Play

Apart from the timing of caffeine and your sleep schedule, another very overlooked factor is the quality of your sleep environment. Scientists have long known that the environment in which you sleep has a huge impact on the quality of your rest. Poor quality of sleep, even if your sleep schedule is regular, can cause health risks that are very much the same as those that arise from irregular sleep patterns.

Here’s an additional tip: make sure your bedroom is conducive to restful sleep. This means keeping your room dark, quiet, and cool. A temperature of around 65°F (18°C) is ideal for most people. Consider investing in a comfortable mattress and pillows, and avoid screen time at least 30 minutes before bed to allow your brain to unwind.

Irregular sleep, in association with taking caffeine in late parts of the day, can risk heart attack and stroke, but a simple maintenance of a sleep schedule, the reduction of consumption of afternoon caffeine, and sleep environmental awareness can definitely safeguard one's heart along with total health.

Your sleep is more than just a time for rest; it's a vital component of your long-term health, and maintaining consistency in your sleep habits is one of the best things you can do for your heart.

‘Sea Or See?’ Donald Trump's Remark Sparks Fresh Cognitive Health Speculation

Updated May 13, 2026 | 06:00 PM IST

SummaryThe White House continues to say that Trump remains in strong health, and added that the President has "unmatched energy, and historic accessibility".
‘Sea Or See?’ Donald Trump's Remark Sparks Fresh Cognitive Health Speculation

US President Donald Trump's attempt to clarify the meaning of "sea" while discussing drug smuggling has again raised concerns of dementia.

While the 79-year-old President rambled between “sea and see” in the middle of discussing drug problems in the US, social media went rife with the rumor of his cognitive decline.

"Drugs coming by sea meaning coming by water. A lot of people don’t know what I mean by sea. They think I mean vision. I’m talking about sea like the sea," he said. He was speaking at the White House, while hosting law enforcement officials for a dinner in the Rose Garden in celebration of National Police Week.

His comments were called out by social media as his apparently worsening cognitive capabilities.

"When he says 'a lot of people' he means 'me.' His cognitive issues are a crisis," one social media user declared, while another admitted, "He’s getting worse."

Trump has spoken on sea and see, during a maternal healthcare event last week, where he also referred to himself as the “father of fertility.”

Earlier, speaking at the White House Small Business Summit, Trump said he has taken the Montreal Cognitive Assessment three times and “aced each one,” claiming a doctor told him it was the first time they had seen a perfect score, The Daily Beast reported.

The US President said he answered the test questions easily, suggesting he is cognitively in good condition—a claim that critics have repeatedly questioned.

“The first question is very easy,” he said. “You have a lion, a bear, an alligator, and a—what’s another good…? A squirrel. Which is the squirrel?” He added that the difficulty increases as the test progresses. “By the time you get to the middle, they’re very tough.”

However, the test’s creator, Canadian neurologist Ziad Nasreddine, has challenged Trump’s claims. “It wasn’t designed to be a test of IQ,” he told nine.com.au. “It was designed to assess normal cognitive performance.”

Experts Claim Trump's Mental Health Is Deteriorating

A group of medical experts, including neurologists, psychiatrists, and other physicians, has sounded the alarm over what they’ve described as Trump’s deteriorating mental health.

The experts have not specifically examined Trump face-to-face. But, they analyzed Trump's statements and behaviors over the past year, and stated that he’s “mentally unfit” and must be removed from office “with the greatest urgency” amid the escalating tension around the world, according to their statement published in The BMJ.

“It is our professional opinion that they (Trump's statements) reflect a rapidly worsening, reality-untethered, increasingly dangerous decline,” the experts said.

They also listed some of Trump’s observable serious medical issues, such as “Marked deterioration in cognitive functioning, evidenced by disorganized and tangential speech, rambling digressions, factual confusions, unexplained sudden changes of course in strategic matters, both national and international, episodes of apparent somnolence during critical public proceedings.”

What The White House Says

The White House has continued to say that Trump remains in strong health.

In October 2025, White House physician Captain Sean Barbabella said the president “continues to demonstrate excellent overall health,” AOl.com reported.

"President Trump’s sharpness, unmatched energy, and historic accessibility stand in stark contrast to what we saw during the last administration when Democrats and other lunatics intentionally covered up Joe Biden’s serious mental and physical decline from the American people,” White House spokesman Davis Ingle was quoted as saying to The Daily Beast.

PCOD vs PCOS vs PMOS: Why The Condition’s Name Has Changed Over Time

Updated May 13, 2026 | 04:00 PM IST

SummaryFrom just being a reproductive or ovarian disorder, PMOS is now being recognized as a complex hormonal and metabolic condition that can affect everything from periods and fertility to weight, insulin resistance, heart health, skin, and mental well-being.
PCOD vs PCOS vs PMOS: Why The Condition’s Name Has Changed Over Time

From Polycystic Ovarian Disease (PCOD) to Polycystic Ovary Syndrome (PCOS) and now Polyendocrine Metabolic Ovarian Syndrome (PMOS) — confused about what the changing terminology means for women’s health and treatment?

What was once seen mainly as a reproductive or ovarian disorder is now being recognized as a complex hormonal and metabolic condition that can affect everything from periods and fertility to weight, insulin resistance, heart health, skin, and mental well-being.

To better understand the distinction between the three, let’s look at how the condition has evolved.

The condition, involving irregular periods, infertility, excess facial hair, and enlarged ovaries containing multiple cysts, was first identified as an ovarian or reproductive disorder in the 1930s by American gynecologists Dr. Irving Stein and Dr. Michael Leventhal. It became known as Stein-Leventhal Syndrome.

Over the years, the term PCOD became widely used, especially in countries like India. The name focused mainly on the presence of multiple ovarian cysts seen on ultrasound scans. It was considered a “disease” affecting ovulation and fertility.

Further, in the 1980s and 1990s, experts discovered that the condition involved hormonal imbalances, insulin resistance, weight gain, diabetes risk, and heart health concerns, among others.

Because it affected multiple body systems, PCOS became the medically preferred global term. The word “syndrome” was used to describe a group of related symptoms rather than a single disease.

However, many experts argued that the name still overemphasized ovarian cysts and fertility, and in 2012, the US National Institutes of Health (NIH) officially recommended changing the name, saying it was misleading because:

  • Not all women with the condition have cysts
  • Ovarian cysts alone are not enough for diagnosis
  • The name ignores the metabolic and hormonal aspects
Importantly, experts said the terminology also delayed diagnosis and contributed to stigma around fertility.

In 2026, global experts publishing in The Lancet proposed the new name -- PMOS – for the condition affecting more than 170 million women worldwide.

The new term PMOS acknowledges that the condition involves:

  • Endocrine health
  • Metabolic health
  • Reproductive health
  • Dermatological health
  • Psychological health.

What Does PMOS Mean?

The new name aims to explain the condition more accurately and comprehensively.

Polyendocrine means it affects multiple hormones in the body.

Metabolic refers to issues linked to weight, insulin, blood sugar, and heart health.

Ovarian highlights its impact on ovulation and reproductive health.

Syndrome refers to a group of symptoms occurring together.

In simple terms, PMOS is a hormonal and metabolic condition that can affect periods, fertility, skin, mood, weight, and long-term health.

What The Name Change Means For Women

Speaking to HealthandMe, Dr Monika Bhatia Director — Obstetrics & Gynaecology Robotic and Laparoscopic Surgeon Cloudnine Group of Hospitals, said that the earlier name was misleading because the "cysts" in PCOS are not real cysts — they are simply small, arrested follicles.

While the name has changed, the message remains the same.

“Behind every diagnosis is a woman trying to understand her body, hormones, emotions, and health. While this condition may affect periods, fertility, metabolism, skin, weight, or mental well-being differently, one thing remains common — it is manageable with the right guidance,” she said.

The core treatment stays the same as the guidelines for treatment have not changed, but the approach becomes wider.

“So instead of just treating the periods, PMOS is now managed as a whole-body condition involving a multidisciplinary team”.

Will there be any change to evaluation?

Dr Muskaan Chhabra, Fertility Specialist, Birla Fertility & IVF, Lajpat Nagar, told HealthandMe that the new name –PMOS- correctly acknowledges that this is a multisystem condition involving complex interactions between insulin, androgens, and neuroendocrine hormones.

In PMOS, the ovaries are one of several systems involved rather than the primary site of the problem.

This “opens the door to more comprehensive clinical evaluation, earlier and more accurate diagnosis, and treatment approaches that address the full hormonal and metabolic picture rather than a narrow reproductive one,” Dr Muskaan said. It will also “drive more integrated and personalized care”.

Hantavirus Can Linger Indoors, Spread Through Contaminated Dust, Says Infectious Disease Expert

Updated May 13, 2026 | 11:45 AM IST

SummaryDr. Vasant C. Nagvekar from Lilavati Hospital said that the Andes strain rarely transmits person-to-person and emphasized the need for global prevention through enhanced surveillance, early detection, vector control, environmental sanitation, and public awareness, particularly amid urbanization, climate change, and ecosystem disruption.

Hantavirus has the potential to linger indoors and spread through contaminated dust, especially in rodent-infested, poorly ventilated spaces, according to infectious disease expert Dr. Vasant C. Nagvekar.

So far, 11 people linked to the MV Hondius cruise ship have been affected. While all passengers have been repatriated and quarantined, the World Health Organization (WHO) anticipates that additional cases may emerge based on observed symptoms.

In an exclusive interview with HealthandMe, Dr. Vasant, a Consultant in Infectious Diseases and Internal Medicine at Lilavati Hospital and Research Center, Mumbai, explained how the virus can spread even within indoor environments. He noted that contaminated dust and surfaces are potential sources of transmission, making proper hygiene and preventive measures crucial.

The expert also stated that the Andes strain rarely transmits person-to-person and emphasized the need for global prevention through enhanced surveillance, early detection, vector control, environmental sanitation, and public awareness, particularly amid urbanization, climate change, and ecosystem disruption.

Here are the excerpts from the interview

Q. How Long Does Hantavirus Survive?

Dr. Vasant: Hantavirus does not survive for long outside a host body and is rapidly inactivated by exposure to sunlight, detergents, and drying.

However, in enclosed indoor environments that are cool with temperatures at 4 degrees Celsius or less, poorly ventilated, and contaminated with rodent urine or feces, the virus may remain infectious for several hours or even longer.

Q. Is Hantavirus Airborne?

Dr. Vasant: Yes, the virus can be transmitted indirectly through the air. However, hantavirus does not circulate freely in the air in the same way as influenza or coronavirus during normal social interactions.

It becomes airborne when contaminated rodent urine, droppings, or nesting materials are disturbed during activities such as sweeping or cleaning. At that point, the virus can be aerosolized and inhaled by people.

Q. How Can Hantavirus Spread Indoors?

Dr. Vasant: Indoor exposure usually takes place in environments where the presence of goes unnoticed – for example, in cabins, storage rooms, warehouses, inside false ceilings, or vacant rooms.

One could be exposed to hantavirus through inhalation of contaminated dust when a room that has not been used for a while is opened or is cleaned without any protective measures.

The reason why hantavirus exposure is alarming is that it usually takes place during normal activities, which we do without even suspecting anything dangerous.

Q. How Does the Andes Strain of Hantavirus Spread?

Dr. Vasant: The Andes hantavirus stands out because, unlike most other hantaviruses, it exhibits evidence of rare person-to-person transmission, mostly through direct and extended contact between people. As a result, this particular strain is highly interesting for scientists studying infectious diseases around the world and is extensively researched as such. It should be noted, however, that person-to-person transmission is very rare in comparison to respiratory pathogens, such as the influenza virus or SARS-CoV-2.

Q. What global strategies are needed to prevent the emergence of new viruses?

Dr. Vasant: What is required from our world in terms of the prevention of new viruses is a globally integrated strategy within the public health sector.

Surveillance systems should become more advanced on community levels, especially when there are high risks of increased contact between humans and animals because of urbanization, climate change, and ecosystem destruction.

Early detection, information exchange at the international level, vector control, environmental sanitation, and public awareness are just as significant. New infection strains cannot remain limited to just being a problem of individual countries.
