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.

More women in the US and UK are seeking testosterone to manage menopause symptoms, with some turning to online pharmacies without a prescription, according to media reports.

There are no US Food and Drug Administration (FDA)-approved testosterone products specifically indicated for women. Australia has approved a low-dose testosterone product for postmenopausal women, while the UK and New Zealand permit some female-dosed formulations, although availability varies.

What’s Happening In The US?

Reuters reported that off-label testosterone use is rising in the US, mainly to treat persistently low sexual desire associated with menopause. Some clinicians are also prescribing testosterone for symptoms such as fatigue and loss of muscle strength, despite a lack of medical guidance supporting these uses.

Prescriptions for low sexual desire reportedly rose 146% between January 2023 and July 2026. However, many pharmacies and health insurers continue to deny these prescriptions.

Why Are UK Women Turning To Testosterone?

The BBC reported that some women in Wales are posing as men to buy testosterone from online pharmacies because of difficulties accessing NHS prescriptions.

There has also been a “very sharp increase” in testosterone referrals to the NHS for postmenopausal women.

Menopause specialist Dr Michelle Olver said she had seen women with testosterone levels up to 12 times the safe level after buying the hormone online, putting them at risk of permanent side effects.

Why Is Testosterone Gaining Attention?

Although testosterone is often called a male hormone, women also produce it, primarily through the ovaries and adrenal glands. Levels generally decline with age.

Some women are prescribed testosterone for distressing loss of sexual desire. Others are seeking it for fatigue, impaired thinking, low mood and loss of muscle strength.

The FDA is set to hold a public workshop on September 17 to examine testosterone use in menopausal women. The agency says off-label use is growing, while questions remain about its effects on sexual function, mood, cognition, muscle and bone health, as well as long-term cardiovascular and breast cancer safety.

What Does The Evidence Say?

Menopause does not automatically mean a woman has a “testosterone deficiency.”

Notably, there is no established testosterone level below which an otherwise healthy woman is diagnosed as testosterone deficient. A blood test alone also cannot determine whether low testosterone is responsible for symptoms such as fatigue, low mood or loss of sexual desire.

However, the Menopause Society and other medical organizations support testosterone use in menopausal women with hypoactive sexual desire disorder.

“We do not have any evidence in women that it will improve muscle mass or bone density or mood or well-being or really any other metric,” said Dr Stephanie Faubion, director of Mayo Clinic's Center for Women's Health and medical director of The Menopause Society.

“What testosterone is being touted for in the lay public and on social media is not really what we have data for,” she said.

Are There Any Side Effects?

According to Cleveland Clinic, testosterone treatment generally isn’t recommended for women with cardiovascular disease, liver disease or hormone-sensitive cancers such as breast or uterine cancer.

Excess testosterone can cause acne, increased facial or body hair and scalp hair loss. Higher doses may also lead to voice deepening and clitoral enlargement, some of which can be irreversible.

Testosterone should therefore not be used in higher doses as a way to boost energy, muscle strength or libido.

BORG Drinking Trend: Why These Viral Alcohol Jugs Can Be Dangerous

Updated Sep 15, 2026 | 06:41 PM IST

SummaryBORG stands for "Blackout Rage Gallon," and it's basically a personal-sized jug loaded with liquor, water, and whatever flavoring you're into. Its packs up to a fifth of liquor. That's about 17 standard drinks. In one jug. And it is meant for one person.
BORG Drinking Trend: Why These Viral Alcohol Jugs Can Be Dangerous

You've probably seen gallon jugs with stuff like "BORG o'clock somewhere" scrawled on them in Sharpies, often showing up at parties. Well, there's actual research on them now, and it's not great.

The study by Rutgers University, published in the Journal of Studies on Alcohol and Drugs, surveyed over 100 college students about their BORG habits. The study finds significant health risks.

What Is BORG?

BORG stands for "Blackout Rage Gallon," and it's basically a personal-sized jug loaded with liquor, water, and whatever flavoring you're into. It started gaining traction around 2020 and hasn't slowed down since the hashtag #borg has racked up millions in views on TikTok alone.

Here's the number that stands out, though. A full BORG can pack up to a fifth of liquor. That's about 17 standard drinks. In one jug. And it is meant for one person.

The study pointed out that drinking games have always been part of college culture. But BORG drinks might be worse than most, mainly because of how they're made. Mixing hard liquor with sweet flavors can make people drink more without realizing how much alcohol they're actually consuming, and the fact that people often share sips of each other's jugs only adds to the risk.

"Excessive drinking in young adults has been fueled by drinking games for many decades. But the mixing of hard liquor and additive flavorings in BORGs may be particularly harmful given the sweetness of the beverage and the lure of sharing one's BORG and tasting others' concoctions," said lead researcher Andrea King, a professor of psychiatry and behavioral neuroscience at the University of Chicago, US.

When Can BORG Drinks Go Wrong?

The actual numbers from the study are rough. Almost a third of students said they'd blacked out from a BORG at some point, not just "drunk," actually blacked out, meaning their brain stopped saving memories from that stretch of time.

Nearly 20 percent of students said they threw up, and nearly 6 in 10 admitted to saying or doing something embarrassing. And this is just the students who actually admitted to having done this. The actual count could be much higher. Some cases were serious enough to end in injuries or trips to the emergency room.

According to the World Health Organization, there is no safe level or risk-free amount of alcohol consumption that does not affect health.

BORGs: The ‘Safe Drinking’ Myth

What's even more interesting, however, is how this trend began in the first place. BORGs were initially promoted on social media as the more responsible choice when it came to drinking. The idea was for everyone to bring their own jug instead of sharing cups, so as to avoid the spread of germs during the pandemic.

Some recipes online even threw in electrolytes or caffeine, supposedly to dodge hangovers or keep people from getting too drunk. Students still shared their BORGs constantly, and the added ingredients did nothing to stop the harmful effects of drinking so much alcohol at once.

Even knowing all this, however, a lot of students said they're not planning to stop. That's part of why this study seems to emphasize the fact that awareness matters so much, both for students and for their parents.

As King put it, "There are choice points along the way, ranging from whether to attend a BORG event, and if one does attend, whether to bring a BORG beverage and how much (if any) alcohol to put in the beverage. It doesn't have to be all-or-none, as being aware and mindful to minimize risks can be key."

Neuro-Protection: How Your 30s And 40s Determine Your 70s And 80s

Updated Sep 15, 2026 | 07:19 AM IST

SummaryA busy life is making chronic stress, poor sleep, physical inactivity, bad diets and extended hours of sitting normal. But these common activities may be quietly contributing to inflammation that’s damaging blood arteries and brain cells over time.

Alzheimer’s disease is normally seen as a disease of old age, something that starts when memory starts to fail in the 70s or 80s. But science has a totally different narrative. Alzheimer’s is not something you ‘catch’ suddenly in old age. It’s a sluggish, degenerative disorder that develops slowly over decades. When a person begins to forget names, ask the same questions, or have trouble with everyday chores, there may have been damage to the brain for years.

This is why neuroprotection should start much earlier, ideally in our 30s and 40s.

Today, most patients only see the neurologist when the symptoms are obvious. Unfortunately, at this stage the disease process has already progressed and therapy options are limited. Doctors and health professionals need to be more open about prevention, to teach younger folks that brain health is established well before retirement age.

Our modern lifestyle is a silent neurological risk. A busy life is making chronic stress, poor sleep, physical inactivity, bad diets and extended hours of sitting normal. But these common activities may be quietly contributing to inflammation that’s damaging blood arteries and brain cells over time. Studies increasingly connect mid-life problems like obesity, diabetes, hypertension and sleep difficulties to a greater risk of dementia in later life.

Sleep is particularly important for removing such toxic substances from the brain. Constant stress boosts cortisol levels, which may interfere with memory areas. A sedentary lifestyle lowers the blood supply to the brain and undermines cognitive resiliency. Something that seems inconsequential today may be important decades from now.

The good news is that prevention is effective. Regular exercise, good sleep, management of stress, social activity, mental stimulation and regular health checks can all help protect the brain. Neuroprotection is not about fear; it’s about awareness and action.

What we decide to do in our 30s and 40s is not just about our careers or lifestyles; it’s about the health of our brains in our 70s and 80s. We need to change the conversation around Alzheimer’s from late-stage therapy to early-life prevention.
