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 measles continues to spread across the United States, with recent case numbers climbing to their highest level in 33 years, growing numbers of Americans are becoming concerned about how at risk they may be.
Health officials in Philadelphia confirmed a potential measles exposure at Philadelphia International Airport and several public transport locations across the city in early January. The Centers for Disease Control and Prevention has also flagged earlier measles outbreaks across Pennsylvania, New Jersey, and New York City.
Adding to the concern, infectious disease tracker BMJGroup reported that measles cases recorded in 2025 are the highest seen since at least 1992.
Against this backdrop, it is important to understand whether measles can be fatal and to recognise the symptoms that should not be ignored.
Yes, measles can be deadly and carries a significant risk of death, according to the Centers for Disease Control and Prevention.
“Measles can lead to serious health complications, including pneumonia, inflammation of the brain known as encephalitis, and death,” the CDC states. “Between one and three out of every 1,000 people infected with measles will die. Around one in five people with measles will require hospital care, and one in every 20 children with measles develops pneumonia, which is the leading cause of measles-related deaths in young children.
“One in every 1,000 people with measles will experience brain swelling, which can result in permanent brain damage.”
According to the Mayo Clinic, measles symptoms usually appear in three distinct stages.
Stage 1: Incubation period (10 to 14 days)
During this phase, there are typically no noticeable or warning symptoms.
Stage 2: Early symptoms begin
Symptoms at this stage may include a dry cough, fever, red and inflamed eyes known as conjunctivitis, a runny nose, and a sore throat.
Stage 3: Acute illness and rash
“In the third stage, a rash begins to develop, usually starting on the face. Small white spots called Koplik spots may appear inside the mouth two to three days after symptoms first appear,” the Mayo Clinic explains. “The measles rash typically shows up three to five days after the initial symptoms.
“Over the following days, the rash spreads to the arms, torso, and legs. Alongside the rash, fever often rises rapidly and can exceed 105 degrees Fahrenheit,” the guidance continues. “Eventually, the fever subsides, and the rash fades from the body starting at the head and moving downward.”
“If individuals aged six months or older are exposed to measles and do not have immunity from prior infection or vaccination, they can receive the measles vaccine within three days of contact with the virus,” the Mayo Clinic advises. “After vaccination, quarantine at home is not required.
“For children up to 11 months old who are exposed and are not immune, a dose of antibodies known as immune globulin can be given within six days of exposure to help the body fight the infection.”
Receiving this antibody treatment requires a 21-day quarantine period.

A notice has been issued for people who use the drug spironolactone. It is commonly prescribed for heart conditions, high blood pressure, and fluid retention. However, doctors say the medication is also used for several other health concerns.
According to the British Association of Dermatologists (BAD), spironolactone is prescribed “off licence” for women dealing with acne, female pattern hair loss, and hirsutism, a condition marked by excessive hair growth in areas such as the chin and upper lip. The NHS also states that spironolactone is a well-established and generally safe medicine that is sometimes used off licence to treat acne. Off licence means the drug is not officially approved for that specific condition under the UK prescribing licence.
Despite this, the NHS says spironolactone is available through the health service and is considered a useful alternative to long-term antibiotics. A study published in 2022 found that the drug is effective and safe for women who have persistent acne.
Spironolactone, sold under the brand name Aldactone, is also used to help manage polycystic ovary syndrome, commonly known as PCOS. However, it is not usually prescribed to men for skin-related conditions.
While the medication can be helpful for many women, experts warn that it does come with side effects and certain dietary restrictions. Here is what patients should know before starting treatment.
The NHS explains that spironolactone does not permanently cure acne, but it can help control breakouts and gradually clear the skin. The drug works slowly, meaning results are not immediate.
Most women begin to see improvement after about three months of use, but treatment usually needs to continue for at least six months. In some cases, it may take the full six months to experience the maximum benefit.
For acne, spironolactone is usually prescribed at doses ranging from 50mg to 150mg per day. Many patients start with 50mg daily for the first month, depending on how well they tolerate the medication and whether any side effects appear.
If there are no concerning side effects and blood test results remain normal, a doctor may increase the dose to 100mg per day. NHS guidance says the tablets should be swallowed whole with water and taken after food.
High potassium levels in the blood, especially in people over 45 or those with heart or kidney disease
Changes in kidney or liver blood tests, which usually return to normal if the dose is reduced or stopped
Cancer, which has been linked to very high doses in animal studies, but not seen in people taking standard doses.
The NHS advises that spironolactone should not be taken during pregnancy or while trying to conceive. It should also be avoided by people with Addison’s disease or serious kidney problems.
Alcohol can worsen certain side effects, such as dizziness, so cutting back on drinking is recommended. Reliable contraception should be used while taking spironolactone, and the combined contraceptive pill may help reduce side effects while also improving acne.
Doctors advise that it is usually safe to try for a baby one month after stopping the medication. The NHS stresses the importance of informing your doctor about any other medicines you are taking before starting spironolactone. This includes ACE inhibitors, anti-inflammatory painkillers such as aspirin or ibuprofen, certain antibiotics, other diuretics, heart medications like digoxin, drugs for high blood pressure, and potassium supplements.
As per Mirror, people taking spironolactone are advised not to use low-sodium salt or salt substitutes such as Lo-Salt, as these products contain high levels of potassium. Using them alongside spironolactone can raise potassium levels to a dangerous range.
The NHS also recommends limiting foods and drinks high in potassium, including bananas, avocados, pulses, nuts, and salmon. A doctor or dietitian can help plan a low-potassium diet if needed.

The NHS has issued advice for anyone taking a widely prescribed medication, warning of possible “serious” side effects. If you are currently on atorvastatin, it’s important to be cautious about what other medicines or supplements you take alongside it.
Atorvastatin belongs to a class of drugs called statins, which help lower cholesterol levels. It is usually prescribed for people with high cholesterol to reduce the risk of heart disease, including heart attacks and strokes.
Your GP may also recommend atorvastatin if you have a family history of heart disease or a long-term condition such as type 1 or type 2 diabetes or rheumatoid arthritis. As with any medicine, it’s vital to follow official guidance on how to take it safely.
On its website, the NHS lists certain “cautions with other medicines.” This means you should check that atorvastatin is safe to take alongside any other drugs or supplements.
The NHS explained: “Some medicines can affect the way atorvastatin works and can increase the chances of you having serious side effects, such as muscle damage.” You should tell your doctor or pharmacist if you are taking any of the following:
If you need to take one of these medicines while on atorvastatin, your doctor may:
These are not all the drugs that can interact with atorvastatin. “For a full list, see the leaflet in your medicine packet or speak to your pharmacist,” the NHS said.
The health service also advised checking with your doctor or pharmacist before taking supplements like St John’s wort or CoQ10 while on atorvastatin.
The NHS lists these common side effects, which affect more than one in 100 people:
“Drinking large amounts of alcohol regularly increases the risk of side effects and liver problems while taking atorvastatin,” the NHS added. “If side effects make you want to stop taking the medicine, speak to your doctor first. They may be due to another cause, and your doctor can suggest lowering the dose or switching medicines.”
Stop taking atorvastatin and contact a doctor or call 111 immediately if you experience:
