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.

Rebecca Pinto, physiotherapist and nutritionist shared a video on her Instagram account where she cites a case of a man who used hair loss treatment and was admitted to hospital on complain of chest pain. She points out that not everything that is available over the counter is safe to use. She says the key ingredients in many easily available hair loss treatment is minoxidil, which could trigger chest pain or angina as it can lower blood pressure.

Health and Me spoke to Dr Sanjay Bhat, Sr Consultant, Interventional Cardiology at Aster CMI Hospital, Bengaluru to fact check this claim and here is what we found out.

Fact Check: Can Minoxidil Cause Severe Chest Pain?

Health and Me asked Dr Bhat if this easily available ingredient could actually cause someone’s life. To this, Dr Bhat explained that it is a commonly used medicine for treating hair loss and is easily available in many pharmacies as a topical solution or form. He said it works by improving blood flow to the hair follicles and helping hair grow. “When used on the scalp as recommended, it is generally safe for most people. However, long-term or excessive use may sometimes cause side effects. Some people may absorb a small amount of the medicine into the bloodstream, which can affect the heart and blood vessels,” he explains.

This could lead to symptoms such as chest pain, rapid heartbeat, dizziness, swelling of the hands or feet, or low blood pressure. “In rare cases, people may go to the emergency room if they feel severe chest discomfort or palpitations. Long-term use without medical advice may also cause scalp irritation or unwanted hair growth on other parts of the body. Therefore, it is important to use minoxidil only as directed and consult a doctor if unusual symptoms appear,” he said.

What To Do If You Feel Chest Pain While Using Minoxidil?

Doctor explains, “If a person develops chest pain after using Minoxidil, the first step is to stop using the medicine and seek medical attention immediately. Doctors will first evaluate the patient to make sure the chest pain is not due to a serious heart problem. This usually includes checking blood pressure, heart rate, oxygen levels, and performing tests such as an electrocardiogram (ECG) and blood tests.”

If minoxidil is suspected to be the cause, treatment mainly focuses on managing the symptoms. Doctors could also give medicines to control heart rate, reduce palpitations, or stabilize blood pressure. Depending on the reports, if the patient has fluid retention or swelling, diuretics may be prescribed to remove excess fluid from the body. Patients may also be monitored in the hospital for a short time if symptoms are severe. Once the symptoms settle, doctors usually advise avoiding minoxidil and may suggest safer alternative treatments for hair loss.

Are There Any Alternative Hair Loss Treatment Without Minoxidil?

The answer is yes. Dr Bhat points out Finasteride, an oral medicine to be one of the common alternatives to minoxidil for hair loss treatments. This medicine works by reducing the hormone DHT, which is linked to male pattern baldness. This also helps in slowing down the hair loss and promoting regrowth.

Platelet Rich Plasma Therapy: This is another alternative available points out Dr Bhat. This is when blood is processed and injected into the scalp to stimulate hair follicles and improve hair thickness.

He also pointed out that doctors often recommend Low Level Laser Therapy, which is a painless treatment using red light lasers to improve blood flow to hair follicles and encourage hair growth.

Lastly, Hair Transplant Surgery is another option for people facing significant hair loss, where follicles from one part of the scalp are moved to bald areas.

“In addition, treatments such as microneedling, nutritional supplements, and treatment of underlying medical conditions may also help improve hair growth,” points out Dr Bhat.

Leucovorin, a high-dose vitamin - folinic acid, were mostly used for treating toxic side effects of chemotherapy, until last year when the White House touted it as a potential treatment for some children with autism. New prescriptions for leucovorin double within weeks of announcement and parents have been trying hard to get it prescribed. This is also because many doctors have been hesitant to prescribe a chemotherapy medicine for childhood autism. They have also stated that not enough evidence is available to prescribe this drug officially.

CNN reported that in Austin, Texas, Meagan Johnson spent four days calling pharmacies across the region searching for leucovorin for her three-year-old son Jack, who has autism. She contacted nearly 40 pharmacies around her home in Pflugerville, hoping to locate the medication.

The effort came after a neurologist agreed to prescribe leucovorin on a trial basis. Johnson’s hope was simple: even a small improvement in her son’s communication would mean a lot. At age three, most children can say hundreds of words, but Jack speaks only about 20, many of which only his mother understands.

However, getting the prescription turned out to be far harder than obtaining it.

Across the United States, pharmacies have been reporting growing difficulty keeping leucovorin tablets in stock. Online support groups for parents of autistic children are now filled with posts from families searching for the medication or asking where it might still be available.

Although leucovorin is not approved specifically for autism, some small studies have suggested that it may help certain children who have unusually low levels of folate in the brain. Families who have tried it report possible improvements in language and social interaction.

A study published in The Lancet found that prescriptions for leucovorin doubled within weeks of the public remarks and remained elevated through early December. Researchers analysed electronic medical records covering nearly 300 million patients to identify the trend.

Experts say such spikes can quickly strain the supply of inexpensive generic drugs.

A Classic Demand-Driven Shortage

Pharmacy supply specialists describe the leucovorin situation as a demand-side shortage. Unlike manufacturing disruptions, these shortages happen when demand rises faster than manufacturers can increase production.

Generic drug manufacturers typically plan production schedules a year or more in advance. Because leucovorin had historically been a niche medication, companies were not prepared for a sudden surge in prescriptions.

As demand increased, pharmacies began running out of tablets. Many manufacturers have placed the drug on allocation or backorder, meaning pharmacies can only order limited quantities.

To ease the pressure, the US Food and Drug Administration allowed temporary imports of leucovorin tablets from Canada and Spain. However, the drug has not yet been officially listed on the FDA’s national drug shortage database, a designation that could trigger additional measures to boost supply.

Families Searching For A Treatment

For parents like Johnson, the debate over research evidence matters less than the possibility of progress.

After days of phone calls, a CVS pharmacist finally located a supply at another branch nearly an hour away. Johnson drove the distance to pick up the medication and gave Jack his first dose that same evening.

The moment brought relief, but also frustration.

Drug shortage advocates say the situation was predictable. Because leucovorin is inexpensive and historically prone to shortages, any sudden increase in demand could easily disrupt supply.

Still, families continue to search for it.

Childhood obesity has been rising steadily across the world, including in India. According to the World Health Organization, the number of children aged 5 to 19 who are overweight or obese has increased more than tenfold over the past four decades.

In India, the Indian Council of Medical Research reports that about 14 percent of children aged 6 to 19 are overweight or obese, with higher rates in urban areas.

Many efforts to prevent obesity focus on healthy eating and physical activity. While these remain essential, research increasingly shows that the stress levels of parents can play a big role in shaping children’s health outcomes.

Stress, simply put, is when the body feels under pressure. Mentally, emotionally, or physically. Parents under stress may have less patience, lower energy, and less ability to maintain healthy routines for their family.

How Parental Stress Leads Childhood Obesity

Additionally, a Obesity Reviews 2017 study also found that parents who suffer from high stress levels are more likely to have irregular eating patterns, snack on unhealthy foods, and engage in less physical activity, which contributes to stressful home environments.

This often leads to a pattern of “comfort eating” and fewer structured meal routines in the house, habits that can be easily picked up and adopted by children. This can pave the way for multiple chronic conditions to develop early on in young children.

Socioeconomic pressures can also worsen the risk of obesity in youngsters. Families experiencing financial stress, job insecurity or long working hours may rely more on convenient fast foods or skip family meals altogether.

According to the World Health Organization (WHO), diet and lifestyle patterns learned in early childhood often persist into adolescence and adulthood, which makes early interventions critical.

How Parenting Styles And Household Atmosphere Matter

A 2020 study in Pediatric Obesity showed that children whose parents reported higher stress levels were more likely to gain excess weight over two years compared with children whose parents reported lower stress.

The home environment can shape a child’s relationship with food. If meals are rushed, distracted, or emotionally tense, children may associate eating with stress rather than nourishment. On the other hand, family routines that include relaxed meals, shared cooking, and parental involvement in active play are linked to healthier weights and better mental health outcomes.

Steps Parents Can Take To Monitor Obesity

• Mindfulness and relaxation techniques: Simple breathing exercises, meditation, or even quiet reading time can lower stress levels. Psychologist Susan Albers notes that mindful parenting improves parent-child interactions and can reduce unhealthy eating patterns.
• Structured routines: Regular meal times, scheduled physical activity, and predictable sleep patterns create stability for children.
• Self-care: Parents who prioritize sleep, exercise, and mental breaks are better able to support their children’s health.
• Healthy family meals: Cooking together, reducing ultra-processed foods, and encouraging fruits and vegetables fosters both nutrition and bonding.

It’s important to note that stress management alone is not enough. Combining emotional support for parents with healthy eating and activity habits is the most effective approach. The American Academy of Pediatrics highlights that integrated strategies addressing diet, activity and family wellbeing can reduce childhood obesity risk more effectively than focusing on nutrition or exercise alone.

Why This Matters For The Future

The impact of a calm, supportive home can be profound. When parents manage stress, children not only eat better and move more, but they also develop emotional resilience and lifelong healthy habits. As Dr. Epel explains, “A child’s wellbeing often mirrors the adult they live with: less stress in parents can mean a healthier start for children.”
