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.
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.
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.
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.
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.

As the summer sun rises high, everyone anticipates relief from seasonal sniffles. Yet increasingly, more and more people are falling ill with cold-like symptoms in warmer weather too. The twist? A new Covid strain—NB.1.8.1—is spreading low-key around the world, from Asia to America and the UK. The challenge is distinguishing between a run-of-the-mill summer cold and a COVID-19 infection.
Typically, respiratory illnesses peak in the colder months when more time is spent indoors and dry air allows viruses to be more easily susceptible. Summer, however, is not virus-free. Parainfluenza virus Type 3, enteroviruses, adenoviruses, and even rhinoviruses are still causing issues in warmer climates. Social events, travel, lack of rest, more alcohol consumption, and air conditioning all set the stage for infections.
Complicating the situation further this summer is the discovery of the NB.1.8.1 Covid strain. Although the World Health Organization (WHO) only recently started monitoring it, scientists are closely monitoring its trajectory and possible implications.
Initially discovered in China in January 2025, NB.1.8.1 has a number of mutations that have caught the eye of the world's health authorities. The good news? There is as yet no evidence to suggest it results in more serious disease. In fact, U.K. Health Security Agency statistics indicate a modest rise in COVID cases with 5.2% of patients positive—up from 4.5% last week.
To date, just 13 of the confirmed NB.1.8.1 cases in the U.K. have been sequenced, the majority of them in April and May. While uncommon at present, the fact that it shares features with other variants of Covid means caution is still crucial.
Both summer colds and Covid-19 have common symptoms such as:
However some symptoms will tend more towards Covid, such as:
There is no guaranteed way to tell the difference between a summer cold and Covid without doing a diagnostic test. Mild COVID-19 symptoms are easily mistaken for other seasonal viruses.
Colds—seasonal or not—are viral illnesses that are transmitted by respiratory droplets, fomites (contaminated surfaces), or close proximity. The main culprits are rhinoviruses, especially during the winter months, but the warmer months experience an upsurge in viruses such as parainfluenza, enteroviruses (coxsackie and echovirus), and adenoviruses.
Summer activities—weddings, concerts, holidays—promote intimate contact between groups, and typical summer behaviors such as drinking, bad sleep, and poor diet compromise immune systems. Air conditioning units, by dehydrating nasal passages, also impair the body's resistance to viral invaders.
The Centers for Disease Control and Prevention (CDC) urges anyone with cold-like symptoms to monitor closely. Covid-19 symptoms can appear two to 14 days after exposure and vary from mild to severe. The virus can be contagious two days before symptoms emerge and up to 10 days—or more—in immunocompromised individuals.
If you’re feeling unwell, the best course of action is to:
Timely treatment, such as antiviral therapy with Paxlovid, is ensured through accurate diagnosis, particularly among high-risk individuals.
While a newer vaccine aimed at fall variants is being developed, the existing vaccines remain protective against NB.1.8.1. The variant is of the "drifter" type from the Omicron lineage, which indicates earlier immunity could still help prevent severe disease.
Dr. Aaron Chen, a Johns Hopkins University virologist, observes, "Although mutation is unavoidable, current vaccines remain effective in preventing hospitalization and complications from new variants, such as NB.1.8.1."
There's no surefire way to completely avoid viruses, unfortunately. But here are some practical tips from experts:
Most people recover from summer colds and mild Covid-19 at home. Supportive care—hydration, over-the-counter pain relief, and rest—is typically enough. Nasal decongestants and lozenges can ease symptoms, while more serious or persistent cases warrant medical consultation.
If you suspect Covid, getting tested is crucial—not only for your health but for the wellbeing of those around you.

The terrifying crash of an Air India flight in Ahmedabad killing 241 people with just one British passenger surviving has sent shockwaves around the world. Although flying is statistically one of the safest ways to travel, such traumatic incidents can revive old terrors in even the most experienced of travelers. To the 25 million Americans who already suffer from aerophobia, the technical name for the fear of flying, this awful news might be more than just upsetting. It might be debilitating.
Mental health experts caution that such events can amplify already-existing anxiety, fueling catastrophic thinking and resulting in severe avoidance of travel. And yet, despite the fear, there are ways to deal with flight anxiety that are evidence-based and even get over it.
Aerophobia refers to a severe, irrational fear of flight. While some may equate it with fear of a plane crash, most individuals afflicted by the condition actually fear more the sense of intense panic that grips them before or in transit. This encompasses fear of confinement in an airplane, losing control of one's flight, or experiencing a panic attack at altitude.
"Aviophobia or aerophobia is very prevalent," states Clinical Psychologist Akansha Tayal. "Prevalence rates are 10% to 35%, and most people feel very uncomfortable, particularly when faced with reports of aviation accidents. The fear itself is usually irrational and disproportionate to the real danger posed."
Symptoms tend to occur across three areas:
Physical: Palpitations of the heart, sweating, dizziness, nausea.
Emotional: Irritability, restlessness, overwhelming fear.
Cognitive: Catastrophic thinking, obsessive worry, avoidance activities.
Even as frightening as crashes might appear, aviation safety has only enhanced. According to a 2023 analysis by MIT scientists, the probability of being killed in a commercial airline accident around the world is approximately 1 in 13.7 million. Even so, the public eye and emotional intensity of aviation disasters often overshadow their statistical infrequency when it comes to those suffering with aerophobia.
This psychological effect availability bias is the reason why tragic headlines seem so close to home and threateningly personal. "Our brains are hardwired to respond to threat cues," says Ms Tayal. "Even an unlikely event will feel like a personal risk when it's sensationalized or emotionally jarring."
If you're avoiding travel, unwilling to get on airplanes, or preoccupied with air safety, you might have clinical aerophobia. In addition to discomfort, you might experience:
While aerophobia can feel paralyzing, it’s highly treatable. Experts recommend a mix of self-help techniques and professional interventions.
Challenge irrational fears by learning facts about flight safety. Avoid sensational news and instead focus on what you’re looking forward to. Keep a mental list of safe flight experiences.
Practice slow breathing with a soothing word such as "peace." It reduces the heart rate and quenches stress hormone activity. Mindfulness techniques and progressive muscle relaxation can also keep your body connected.
Rehearse a peaceful flight experience in your mind—from getting on the plane to arrival. Visualization can get your brain thinking about flying as an ordinary, safe thing.
Crossword puzzles, backward counting, reading, or soothing videos can break the worry loop mid-flight.
Travel with a supportive friend and inform them of your triggers. Advance briefing with sympathetic airline personnel can also smooth pre-flight anxiety.
Begin with short flights or utilize flight simulators to rewire gradually, exposing yourself to incrementally longer flights. Safe repetition is shown to decrease sensitivity over time.
Cognitive Behavioral Therapy (CBT) and Exposure Therapy are gold-standard treatments. EMDR (Eye Movement Desensitization and Reprocessing) and Virtual Reality Therapy are increasingly proving to be effective treatments.
"Any psychologist can help the person walk through CBT in order to cope with irrational thoughts," Ms Tayal says. "For tackling these maladaptive thoughts and irrational fears, we do graded exposure, EMDR, or virtual reality. Relaxation training, mindfulness, and grounding are all important too."
Grounding Techniques: Utilize the 5 senses to remain engaged in the moment.
Mindfulness: Practice non-judgmental attention to your thoughts and bodily sensations.
Progressive Muscle Relaxation: Release tension to decrease physiological arousal.
Professional Monitoring: When anxiety arises from underlying trauma or generalized anxiety disorder, a psychiatrist may assist in regulating underlying causes.
Yes—but long-term results are promising. Research indicates that individuals treated with CBT tend to sustain outcomes for three years or longer. Occasional therapy "booster shots" or regular practice of coping techniques can ward off relapse.
There is no guaranteed way to prevent aerophobia, but there are some habits of daily living that can definitely minimize its effect. Steering clear of such stimulants as alcohol or caffeine prior to a flight will keep anxiety under control. Open discussion of your apprehension with intimate family members, friends, or a support group is also crucial, as it helps lessen the emotional load. Shying away from solitary confinement is equally crucial—sharing space with people who are going through the same thing can provide reassurance and confirmation. Finally, remaining attuned to your own mental health and being proactive in seeking assistance early, particularly if symptoms persist or intensify, can make a tangible difference in dealing with flight-related anxiety.
Flight anxiety exists, and tragedies such as the Air India crash can be daunting but you are not alone, and your fear is not something to be ashamed of. With appropriate tools, techniques, and support, the skies don't have to be so frightening.

Ananda Lewis, celebrated TV host known for her authenticity and warmth, passed away at 52 after a long and brave battle with breast cancer. Once a beloved face on BET’s Teen Summit and MTV’s Total Request Live, she used her platform to engage young audiences with pressing social issues and celebrity interviews that left a mark.
Lewis first came into the spotlight through BET’s Teen Summit, where she led candid conversations on challenges facing Black youth. Her interviews with figures like Kobe Bryant, Tupac Shakur, and Hillary Clinton earned her critical acclaim, including an NAACP Image Award.
In 1997, she joined MTV, becoming a key voice on MTV Live, Hot Zone, and TRL. Though her move sparked criticism, she remained unapologetic. “Growth is necessary,” she told the Associated Press. “You’ve got to get out there and live your life.”
She later launched The Ananda Lewis Show in 2001, a daytime talk show aimed at real conversations, even if it followed a familiar format. The show lasted one season, but Lewis remained a powerful presence, later joining The Insider as a correspondent.
In 2020, Lewis revealed that she had been living with stage 3 breast cancer since 2018—later advancing to stage 4. Her diagnosis came after years of ignoring persistent inflammation linked to mastitis from breastfeeding. A lump discovered in her right breast led to a biopsy, confirming it was invasive carcinoma.
Instead of following a conventional medical path, Lewis chose alternative treatments. “I wanted to understand why my body created cancer and how to change the terrain,” she explained. She focused on diet changes, stress management, detoxing, and holistic therapies like high-dose vitamin C, acupuncture, and cryoablation.
Lewis moved to Arizona in 2020 for 16 weeks of intensive integrative treatment. Her cancer reduced from stage 3 to 2 and was no longer in her lymph nodes. But the journey wasn’t without hardship—financial struggles and insurance lapses made consistent treatment difficult.
In early 2023, a scan showed the tumor had grown slightly, but it had not spread. She underwent electrical ablation in Mexico, which unfortunately didn’t succeed. By October 2023, a PET scan confirmed the cancer had advanced to stage 4. Still, Lewis continued treatment and saw significant improvement by January 2024.
Lewis was candid about her journey, using her story to raise awareness about early detection and holistic health. “Stage 4 doesn’t mean the end,” she said. “It means I have to do more.”
Her message to women was clear: be proactive. Prioritize mammograms, manage stress, sleep well, and adopt a clean lifestyle. “If I had known what I know now ten years ago, perhaps I wouldn’t have ended up here,” she said.
“I want to look back and say—I did that exactly how I wanted to,” Lewis reflected. Her legacy is one of resilience, wisdom, and an enduring belief in the right to choose one’s own path—even through cancer.
