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.

The NHS has issued an alert for anyone taking a widely used heart medication. People are being advised to watch for serious warning signs, including yellowing of the skin or “nosebleeds lasting more than 10 minutes.”

What Is Propranolol?

Propranolol is a beta blocker that slows the heart rate and relaxes blood vessels, helping lower blood pressure and reduce the heart’s oxygen demand. It is also prescribed to ease symptoms of anxiety, such as trembling or excessive sweating, and can help prevent migraines. The medication is prescription-only but is commonly prescribed throughout the UK.

According to the Mirror, the British Heart Foundation reports that more than 50 million beta blocker prescriptions are issued in the UK each year, including for propranolol. Patients usually take it once a day, in either a standard or slow-release form.

While propranolol is generally safe, it does carry possible side effects. The NHS advises contacting 111 immediately if serious symptoms affecting the blood or kidneys appear.

The NHS notes: “Like all medicines, propranolol can cause side effects in some people, but many experience none or only minor effects. Side effects often ease as your body adjusts to the medication.”

Propranolol Side Effects

Common side effects include headaches, fatigue, weakness, cold fingers or toes, nausea, and stomach discomfort. While most people over 12 can safely take propranolol, the NHS recommends consulting a doctor first if you have a history of low blood pressure, heart failure, depression, or diabetes.

More serious reactions can occur, including yellowing of the eyes or skin, pale stools, or dark urine. The NHS also warns of nosebleeds lasting longer than 10 minutes, unexplained bruising, or increased tendency to bruise easily.

Anyone experiencing these warning signs should contact a doctor or call 111 immediately. The NHS also cautions against stopping propranolol abruptly without medical guidance, as this could trigger severe heart problems, including chest pain or even a heart attack.

Who Should Be Extra Cautious With Propranolol

While propranolol is widely prescribed and generally safe for most adults, certain people need to monitor themselves more closely or consult their doctor before use. Those with low blood pressure, heart failure, slow heart rates, diabetes, respiratory conditions like asthma, or a history of depression may face higher risks of side effects. Pregnant or breastfeeding women should also speak to a healthcare professional before taking the medication.

The NHS emphasizes that even minor symptoms—like unusual fatigue, dizziness, or cold hands and feet—should not be ignored, especially if they worsen over time. Monitoring for these effects early can prevent more serious complications.

Always consult a qualified healthcare provider before starting, stopping, or changing any medication. If you experience any side effects or unusual symptoms while taking propranolol or any other prescription medicine, seek medical attention immediately.

A California man died last weekend after eating so-called death cap mushrooms, marking the third fatality linked to the toxic fungi in the state since November.

Health officials say California is seeing an unusually high number of mushroom poisonings this season. Between November 18 and January 4, at least 35 cases were reported statewide. In a typical year, the number is usually fewer than five.

“This year’s figures are far beyond what we normally see,” said Sheri Cardo, a communications specialist with the California Department of Public Health.

California Resident Dies After Eating Death Cap Mushrooms

At least three people have now lost their lives in California due to death cap mushroom poisoning since November. Media reports indicate a sharp rise in cases tied to foraged wild mushrooms, with more than 35 poisonings recorded over the past three months.

“The numbers we’re dealing with this year are comparatively off the charts,” Cardo told NBC News.

The most recent death occurred in Sonoma County and was the first fatal wild mushroom poisoning reported there this season, according to county health officials.

Dr. Michael Stacey, interim health officer for Sonoma County, urged residents to avoid eating wild mushrooms unless they are purchased from reliable grocery stores or licensed sellers. He warned that death cap mushrooms can look strikingly similar to safe, edible varieties.

What Is Death Cap Mushroom Poisoning?

Death cap mushrooms, scientifically known as Amanita phalloides, are among the most poisonous mushrooms in the world. They commonly grow beneath oak trees and can be found in parks, gardens, and wooded areas.

Experts say these mushrooms are often mistaken for edible types because of their appearance. Typical features include:

• A smooth cap that may appear whitish, pale yellow, light brown, or green
• White gills underneath the cap
• A white spore print
• A cup-like structure called a volva at the base of the stem
• A ring, known as an annulus, around the stem

Death Cap Mushroom Symptoms

Symptoms usually begin between six and 24 hours after ingestion. Early signs often include stomach pain, nausea, vomiting, and diarrhoea.

In many cases, symptoms ease or disappear after one or two days, which can create a false sense of recovery. By that point, however, the toxins may have already caused severe damage to the liver.

According to experts, the poison responsible, known as amatoxin, can seriously harm the liver, kidneys, and digestive system. Without prompt treatment, the damage can be fatal.

U.S. Poison Centers receive an average of about 52 calls each year related to amatoxin exposure, said Hallen-Adams, though not every case is officially reported.

Is the Risk Easing?

The danger may now be starting to decline in parts of California. Mike McCurdy, president of the Mycological Society of San Francisco, said he has noticed far fewer death cap mushrooms during recent foraging trips.

Earlier this winter, McCurdy said he spotted hundreds of death caps during a two- to three-hour walk in Sonoma County. On a recent outing near Lafayette, California, he found just one. “I think we’re getting close to the end,” he said.

Nearly four years ago, Teresa Sanchez was in Mexico for a medical procedure when her right eye began to feel unusually dry and irritated. At first, it seemed minor. She assumed her contact lens might be torn or that the switch from daily lenses to monthly ones was causing dryness. She even wondered if her body was fighting off an infection, as per CNN.

What she did not realize at the time was that a microscopic organism was slowly attacking her cornea. Over the next three months, the parasite caused irreversible damage to her vision and triggered searing pain that spread across her head.

“I couldn’t even keep the blinds open in my room,” said Sanchez, now 33 and living in Las Vegas. “Light would cause unbearable pain. That’s when I knew something was seriously wrong.”

By then, she had already seen multiple optometrists and had been misdiagnosed. Frustrated and desperate for answers, Sanchez began researching her symptoms on her own.

What Is Acanthamoeba Keratitis?

Online searches led Sanchez to a condition she had never heard of: acanthamoeba keratitis. An eye specialist later confirmed it. Keratitis refers to inflammation of the cornea, the clear, dome-shaped layer at the front of the eye that plays a central role in focusing vision. Acanthamoeba is a microscopic, single-celled organism that cannot be seen without a microscope.

According to Dr. Jacob Lorenzo-Morales, a professor of parasitology at the University of La Laguna in Spain, acanthamoeba is commonly found in soil and water. It does not require a host to survive, which makes it especially resilient.

Once the organism comes into contact with the eye, it can attach itself to the cornea. Dr. Paul Barney, an optometric physician and director at the Pacific Cataract and Laser Institute in Alaska, explained that even tiny breaks in the corneal surface can allow the parasite to burrow deeper into the eye.

Why Contact Lens Wearers Face Higher Risk?

Acanthamoeba keratitis is considered rare. Based on data from 20 countries, including the UK, India, the US, Canada and Brazil, there are more than 23,000 cases worldwide each year. Yet a striking pattern stands out. Between 85% and 95% of people who develop the infection wear contact lenses.

Contact lenses can cause microscopic abrasions on the cornea, creating an entry point for the parasite. The organism can also cling to the lens itself or become trapped between the lens and the eye, making it easier to penetrate the corneal tissue.

“If it’s not diagnosed early and treated aggressively, the outcome can be devastating,” Barney said. “The parasite feeds on the cornea, triggering inflammation and tissue damage that can lead to permanent vision loss.”

In some cases, vision can be partially restored with treatment. Others require a corneal transplant.

A Parasite Built To Survive

Treating acanthamoeba keratitis is especially difficult because the organism has strong defense mechanisms. It can sense threats and respond by forming a cyst, allowing it to lie dormant for months or even years.

This resilience means treatment often stretches over long periods and involves intense discomfort. Because the eye is extremely sensitive, patients must work closely with specialists and strictly follow treatment instructions.

Why The Condition Is Often Missed?

Early diagnosis is one of the biggest challenges Because acanthamoeba keratitis is uncommon, many optometrists may not recognize it right away. As a result, many contact lens users only learn about the condition after they develop it or come across viral videos discussing it online.

Many patients have expressed surprise that they were never clearly warned about the risks of wearing contacts while showering or swimming.

The Contact Lens Society of America emphasized that contact lenses are medical devices and require strict hygiene. This includes avoiding water exposure during swimming, showering or sleeping. The organization also stressed the importance of patients asking questions and carefully reviewing care instructions.

Acanthamoeba Keratitis: Symptoms That Mimic Other Eye Infections

In addition to severe pain and light sensitivity, acanthamoeba keratitis can cause redness, blurred vision, dryness, excessive tearing and the sensation that something is stuck in the eye.

Because these symptoms overlap with other conditions, misdiagnosis is common. Barney said the infection is frequently mistaken for herpes simplex keratitis, a major cause of infection-related blindness. In its earliest stages, it can even resemble pink eye.

That was the case for Sanchez. Her first optometrist diagnosed pink eye. The prescribed drops blurred her vision. A second optometrist suspected a bacterial infection, and while antibiotic drops offered brief relief, she soon lost vision in the affected eye.

Acanthamoeba Keratitis: How To Reduce Your Risk?

Experts stress that contact lens hygiene is critical. Always clean and store lenses using approved contact lens solution, never water. The solution in your lens case should be replaced daily. Wash and dry your hands thoroughly before handling lenses.

Sleeping in contact lenses should be avoided, as it increases dryness, irritation and the risk of corneal damage. Daily disposable lenses may lower infection risk compared to monthly lenses.

For water-based activities, glasses or prescription goggles are safer options. Some people may also consider vision correction surgery after discussing risks and suitability with a doctor.
