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.

New research suggests that mothers who give birth by C-section (cesarean delivery) are more likely to have two major problems afterward: severe pain that disrupts sleep and daily activities, and a higher chance of developing sleep problems.

This study, presented at the ANESTHESIOLOGY 2025 annual meeting, highlights a crucial issue. People often forget how important sleep is when a mother is recovering. Sleep is key to a new mother's mental and physical health. The severe pain and lack of sleep linked to C-sections can cause big issues like postpartum depression, trouble thinking and remembering things, and extreme tiredness. All of this can make it harder for the mother to bond with her baby and have good relationships with family.

What Is A C-Section Birth?

According to Mayo Clinic, a C-section aka (cesarean delivery), is a surgery used to deliver a baby. It involves making surgical cuts (incisions) in the mother's belly and uterus to take the baby out.

A C-section may be planned ahead of time if the mother has certain complications during pregnancy, or if she has already had a C-section before. However, for a mother's first baby, the decision to do a C-section is usually made after labor has already started.

If you are pregnant, understanding the reasons for a C-section and what to expect during recovery can help you feel more prepared. Health professionals might recommend a C-section for several important reasons.

A C-section may be needed if labor stalls, the baby is under stress, or is in an unusual position (breech/transverse). Other reasons include carrying multiples, problems like placenta previa or cord prolapse, a physical blockage, the mother's serious health issues, or a past C-section.

How Is Health Affected After Childbirth?

The research included two main parts: talking to mothers (qualitative analysis) and analyzing a large database (quantitative analysis). For the first part, researchers interviewed 41 new mothers about their pain and sleep. They found a striking difference based on the delivery method:

Over two-thirds of mothers who had a C-section (both planned and unplanned) reported severe pain that made it hard to sleep and do daily tasks.

In comparison, only 8% of mothers who had a vaginal birth reported this level of severe, disruptive pain.

Can You Develop A Sleeping Disorder After C-Section?

For the second part of the study, researchers looked at a national insurance database containing information from more than 1.5 million mothers who gave birth between 2008 and 2021.

This analysis showed that mothers who had a C-section were 16% more likely to be diagnosed with a new sleep disorder (such as insomnia, sleep deprivation, or sleep apnea) between one month and one year after delivery, compared to those who delivered vaginally.

The lead author, Moe Takenoshita, M.B.B.Ch., from Stanford University, stressed the importance of managing pain well, especially for C-section recovery, since untreated pain worsens sleep. To help improve sleep, mothers can try several measures:

• Manage pain adequately with medication.
• Exercise regularly (as soon as it’s safe to do so).
• Sleep when the baby sleeps (napping during the day).
• Avoid caffeine or alcohol late in the day.
• Relax before bed with activities like taking a bath or practicing deep breathing.

Dr. Takenoshita noted that about one-third of all U.S. births are C-sections. She advised that anyone planning a C-section should understand the link to more severe pain and a higher risk of sleep problems. She urged all new mothers with sleep issues to discuss their concerns with their doctor for advice or a referral to a specialist.

A major new report from the World Health Organization (WHO) has delivered bad news: one out of every six serious infections confirmed in labs worldwide last year could not be killed by the antibiotics meant to treat them.

Between 2018 and 2023, the problem of antibiotics failing (called resistance) got much worse. For many common types of germs, resistance went up by 5% to 15% every year. The growing inability of these essential medicines to work is a huge threat to people everywhere.

What is Antibiotic Resistance?

According to the National Foundation for Infectious Diseases, antibiotic resistance happens when bacteria learn to withstand the medicines(antibiotics) that are supposed to kill them. It's like the bacteria have developed a suit of armor against the drug.

When this happens, doctors have to switch to different antibiotics. These backup medicines might not work as well or might cause more side effects. Sometimes, a bacteria can become resistant to all available drugs, which leaves the patient with a dangerous infection that doctors have no way to treat. The alarmingly is that these tough, drug-resistant bacteria can spread from one person to another, both in hospitals and at home.

What Antibiotics Are People Becoming Resistant To?

The WHO's latest report is the most detailed look yet at this issue. It reports on how much resistance exists across 22 different antibiotics—the common drugs used to treat everyday illnesses. The report focused on eight common types of bacteria that cause things like:

• Urinary tract infections (UTIs)
• Stomach and intestinal infections
• Dangerous blood infections
• The sexually transmitted disease gonorrhoea

These germs include well-known ones like E. coli and the bacteria that cause staph infections.

Where Is Antibiotic Resistance A Big Problem?

The risk of antibiotics failing is not the same worldwide. It's highest in Southeast Asia and the Eastern Mediterranean, where one in three reported infections were resistant. In the African region, it was one in five. Resistance is also more common and getting worse in places that don't have good hospitals or labs to quickly find out what type of bacteria is causing an illness and what drug might work.

Dr. Tedros Adhanom Ghebreyesus, the head of the WHO, said that the rise of this resistance is "outpacing advances in modern medicine," putting families' health at risk. He urged everyone to use antibiotics carefully, and stressed the need for better tests, newer medicines, and stronger systems to prevent infections in the first place.

How Does Antibiotic Resistance Cause Us Problems?

The report warns that a type of bacteria known as Gram-negative bacteria is becoming the most dangerous threat globally. The countries least able to fight these infections are being hit the hardest.

• Two types, E. coli and K. pneumoniae, are the most common drug-resistant germs found in life-threatening blood infections. These infections can quickly lead to the body shutting down and death.
• Globally, the standard, first-choice antibiotic is failing against over 40% of E. coli and over 55% of K. pneumoniae.
• In Africa, resistance to this key antibiotic is now higher than 70%.

Even the last-resort, powerful antibiotics that doctors save for only the worst cases are starting to fail. These "last-resort" drugs are often very expensive and hard to find, especially in poorer countries, leaving doctors with no good options.

Can We Resolve This Issue?

On a positive note, more countries are starting to report data to the WHO's tracking system (called GLASS). The number has grown from 25 countries to 104 countries in the last seven years.

However, almost half of the world’s countries still didn't report data last year, and many that did still don't have good enough systems to track the problem accurately. Often, the countries that need help the most are the ones that can’t measure their own problem.

The WHO is urging all countries to work together to fight this by strengthening health systems and tracking resistance in people, animals, and the environment. The goal is for every country to report good-quality data on antibiotic resistance by 2030 so the world can clearly see the problem and decide how to fix it.

In light of growing concerns about harmful side effects linked to certain medicines, including the recent controversy over Coldrif syrup, authorities have now banned two more cough syrups after traces of diethylene glycol (DEG) were found. This chemical has already been linked to 22 deaths in the country.

While all fatalities so far have been connected to Coldrif, regulators in India, the world’s third-largest producer of medicines have advised people to avoid Respifresh TR and ReLife as well, since DEG contamination was detected in them during inspections. None of these products had been exported.

With cough syrups becoming a growing concern, we spoke with Dr. Umashankar Sharma, Medical In-charge (B.N.Y.S), Kailash Institute of Naturopathy, Ayurveda & Yoga, who shared safe alternatives and home remedies that parents can use to keep their children safe.

What Is The Coldrif Cough Syrup Row?

The Central Drugs Standard Control Organisation (CDSCO) has informed the World Health Organization (WHO) that three cough syrups, Coldrif, Respifresh TR, and ReLife have been recalled and their production has been stopped. According to reports by PTI, none of these medicines were exported from India.

The syrups were found to contain DEG, a chemical normally used in industrial processes, which can be extremely harmful if ingested, especially by children. The WHO highlighted the severity of the contamination: Coldrif was found to contain nearly 50% diethylene glycol, a toxic industrial antifreeze. The other two syrups contained the same chemical in smaller amounts.

Last week, the owner of Sresan Pharmaceutical was arrested, and local authorities have revoked the company’s manufacturing licence.

How Does Cough Syrup Become Deadly?

Some cough syrups are made using diethylene glycol (DEG) or ethylene glycol (EG). These chemicals are colourless, odourless, and sweet-tasting, which makes them seem harmless. They are also cheap, which tempts some manufacturers to use them instead of safer, more expensive sweeteners in children’s medicines.

However, DEG and EG are highly toxic, especially for kids. Even small amounts can cause severe problems, including breathing difficulties, kidney failure, long-term disability, or death. For this reason, their use in medicines is banned in many countries. In India, DEG is only allowed in medications at very low levels which is 0.1% or less.

Safe Alternatives For Cough Syrups In India

Coughs in children are often caused by viral infections, allergies, or environmental irritants such as dust or smoke. Many over-the-counter syrups are not recommended for young kids as they may have side effects and offer little relief.

Dr. Umashankar recommends several safe home remedies that can ease a child’s discomfort naturally. He says, “Warm liquids like soups, clear broths, or mild herbal teas, such as chamomile, help keep the throat moist and reduce irritation. Honey is a great natural option for children over one year; half to one teaspoon before bedtime can help calm night-time coughing.”

He also suggests using a cool-mist humidifier in the child’s room to add moisture to the air, which can loosen mucus and ease breathing. Saline nasal drops or a short steam session in a warm shower can also help relieve congestion.

Ensuring the child gets plenty of rest and stays hydrated with water or warm drinks is essential. Slightly elevating their head with an extra pillow at night can reduce coughing while they sleep..

These remedies are generally safe and effective. However, if the cough persists for more than two weeks, or if the child experiences high fever, wheezing, or difficulty breathing, it’s important to consult a doctor to rule out more serious conditions.
