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.

Delhi finds itself in a little relief as the AQI of the city has dropped to 221 as per the CAQM. GRAP IV restrictions have also been lifted, however, pollution and smog continues to take over the city. The Meteorological Department has issued a yellow alert for the next few days, which could affect road and air traffic.

While GRAP IV is now removed, measures under GRAP I, II, and III will continue. As per the IMD forecast, this is what could happen for the next 5 days in Delhi

• December 26: Dense fog will prevail in the morning. Visibility is likely to be low.
• December 27: Yellow alert, dense fog in the morning and afternoon.
• December 28: Yellow alert, moderate to dense fog expected in the early morning.
• December 29-30: Fog will reduce slightly, but moderate haze will prevail in the morning.

Union Transport Minister On Delhi's Pollution

Nitin Gadkari, Union Minister of Road Transport and Highways also highlighted the alarming conditions of Delhi's smog and pollution. He said, "I stay for hardly two days in Delhi, and get an infection," as he spoke on how pollution impacts one's health conditions. However, he did speak on the severity of pollution and highlighted how the transport sector could play a huge role to bring relief to Delhi.

He highlighted that fuel combustion and transport emission leads to most of Delhi pollution.

In an interview with the news agency ANI, the minister also said that his ministry and Central Government are working on several projects and initiatives that will free Delhi from air pollution in the next five years.

Gadkari stated that the Ministry of Road Transport and Highways is undertaking projects worth Rs 1 lakh crore in Delhi to ease traffic congestion. He stated that all these efforts will not only help free Delhi of air pollution but also reduce the country's imports, increase job opportunities, and help farmers.

Electric Buses, Cars, and Scooters

The minister highlighted that 40% of the air pollution in the National Capital region is due to the burning of fossil fuels. In this regard, the government introduced electric buses in the city and enabled automakers to introduce electric cars and two-wheelers in the country.

He further stated that alternate fuel vehicles, such as those that run on CNG, LPG, and flex fuels (E20), are also being introduced and that all these efforts combined will reduce the city's pollution levels.

CNG And Bitumin From Rice Straw

Gadkari pointed out that nearly 200 lakh tonnes of rice straw or parali is burnt in Haryana and Punjab, a major cause of air pollution in the Delhi-NCR region. In this regard, the government is setting up 400 plants to convert the rice straw into CNG. At the moment, 60 plants are operational.

The minister also discussed a new project in Panipat in which rice straw is being used to create 1 lakh litres of Ethanol, 1.5 tonnes of bitumen, and 78,000 tonnes of jet fuel.

As the year draws to a close and 2026 approaches, most women find themselves juggling work deadlines, family responsibilities, and festive plans. In the middle of it all, personal health often slips to the bottom of the list. But doctors say this is exactly the time to pause and take stock of your body, especially your reproductive and hormonal health.

“Annual gynecological screening is one of the simplest ways to prevent silent illnesses, detect early changes, and understand your reproductive health better,” says Dr Tanveer Aujla, Consultant Obstetrician and Gynecologist at Motherhood Hospitals, Noida. Many common conditions show little to no symptoms in the early stages, making routine testing crucial.

Why yearly gynecological check-ups matter

Women often ignore subtle signs like fatigue, irregular periods, unexplained weight changes, or mood swings, assuming they are part of a busy lifestyle. According to Dr Aujla, this delay can be risky. “Conditions like cervical abnormalities, breast lumps, thyroid disorders, vitamin deficiencies, or hormonal imbalance often develop quietly and show symptoms only later,” she explains. A yearly check-up helps catch problems early and allows women to plan their health with confidence, especially if pregnancy is on the horizon.

Pap smear and HPV testing for cervical health

One of the most important screenings is the Pap smear combined with HPV testing. The Pap test looks for abnormal cells on the cervix, while the HPV test detects high-risk viruses responsible for most cervical cancers. “Together, they form a powerful screening tool,” Dr Aujla says. Women between 25 and 65 years should undergo this test every three to five years, or as advised by their doctor.

Breast screening for early detection

Breast health should never be overlooked. Dr Aujla advises yearly mammograms for women above 40, along with clinical breast examinations or ultrasound scans when needed. “These screenings help identify lumps, cysts, or early tissue changes,” she notes. She also stresses the importance of monthly self-examination to check for lumps, pain, or changes like inverted nipples.

Thyroid testing for unexplained symptoms

Thyroid disorders are extremely common in women and often remain undiagnosed. “A simple TSH, T3, and T4 test can explain symptoms like fatigue, mood swings, irregular periods, weight changes, or fertility issues,” says Dr Aujla. Early diagnosis can significantly improve quality of life and prevent long-term complications.

Fertility markers and preconception screening

Tests like AMH offer insight into ovarian reserve and help women plan their reproductive timelines. Dr Aujla points out that this is especially important for women with PCOS, irregular cycles, or delayed family planning. Preconception screening, which includes anemia levels, vitamin D, rubella immunity, blood sugar, and hormonal panels, ensures the body is prepared for a safe pregnancy.

Other essential health screenings

Women over 30 or those with a sedentary lifestyle should also get diabetes and cholesterol tests. Bone health panels checking calcium and vitamin D help prevent future osteoporosis. STI screening is equally important, as infections like chlamydia or gonorrhea can silently damage reproductive health if left untreated.

“Whether you are planning pregnancy or simply want to stay healthy, these tests offer clarity, confidence, and peace of mind,” Dr Aujla concludes. Taking time for these screenings before the year ends is a small step that can protect your health for years to come.

Santa Claus is bad for your health! This is a statement by Dr Nathan Grills, a Public Health Fellow in the Department of Epidemiology and Preventative Medicine, Monash University, Australia. Why is he saying this right ahead of Christmas?

Writing for an article in the British Medical Journal's Christmas issue (BMJ), he says, "Santa only needs to affect health by 0.1% to damage million of lives". He says it would be better if his popularity was rather used to promote healthy living.

Why Is Santa Claus Unhealthy?

Santa Claus's portrayal is where the concerns lie. This was not the first time someone has talked about. In fact, The Conversation in December 2024, talked about this exactly. If you look at Santa, he stands anywhere between 5'6" to 6'6" and weighs between 80Kgs to 136Kgs. He also carries a lot of weight around his belly, which, some may say, keeps him insulated as he sleighs through the snowy lands, but is sure overweight and obese. These portrayal promotes an unhealthy living.

Dr Grils also writes that Santa should rather share Rudolf's snack of carrots and celery sticks than brandy and mince pies, and swap his reindeer for a bike or a walk.

After reviewing existing literature and online sources to understand Santa Claus’s possible impact on public health, the analysis found no peer-reviewed studies directly addressing the issue. What did stand out, however, was the exceptionally high level of awareness of Santa among children. In fact, surveys of American schoolchildren showed that Santa Claus was recognized more widely than almost any other fictional character, second only to Ronald McDonald.

The doctor says that Santa is also used for selling products, which are mostly harmful, and this happens on global scale, which means, people get inspired. "Santa sells, and sometimes he sells harmful products. Like Coca-Cola, Santa has become a major export item to the developing world."

While Santa has been banned from smoking, but his images of enjoying a pipe or cigar are easily found on Christmas cards. The depiction of Santa does form a public perception, argues the doctor.

Dr Grill also notes that Santa may be promoting potential drink-driving, especially when someone follows the tradition to leave him a brandy to wish him well on his travels, while he has billion houses to visit.

Can Santa Spread Diseases?

Dr Grill says that he can spread diseases. If Santa sneezes or coughs around 10 times a day, all the children who sit on his lap may also end up catching the flu along with their Christmas presents.

However, it is important to note that these are views expressed by the doctor and no actual studies have been conducted on the same, Though Dr Grill does indicate for more research before calling for authorities to regulate Santa's activities. For now, Dr Grill proposes a new image for Santa, a healthier one. A slim Santa on a treadmill.
