Can't leave your house without your earphones, airpods or headphones? Well, you aren't alone. There are millions of others who feel the same. However, do not be surprised if I tell you that it may lead to memory loss and dementia. According to the National Library of Medicine, the auditory nerve, which carries sound signals to the brain, when constantly bombarded with loud noises, starts transmitting weaker signals. This forces the brain to work harder to interpret the sound, leading to cognitive overload. Prolonged cognitive strain can eventually pave the way for dementia and memory loss.

Long-term headphone use also affects brain function directly. High decibel levels of noise can damage the insulation of nerve fibres that carry auditory signals to the brain, disrupting the flow of information. Moreover, the electromagnetic waves produced by headphones have been linked to problems like headaches, fatigue, and, in some cases, neurological discomfort.

Beyond The Brain, Headphones Can Make You Deaf

Empirical evidence shows that nearly one billion young people are at risk of hearing loss due to excessive exposure to loud music through headphones. For the uninitiated, sound intensity is measured in decibels. Prolonged exposure to noise above 85 decibels can be harmful to hearing. Music listened to at maximum volume using headphones often falls in the range of 85 to 120 decibels, a level capable of causing significant hearing damage over time.

Studies Show The Ill Effects

According to a recent survey in the UK, a staggering 65% of students admitted to listening to music at maximum volume through their headphones. A similar study revealed that adolescents exposed to high noise levels via headphones in noisy environments experienced a hearing loss prevalence of 22.6%. Those who used earphones for 80 minutes or more per day had a hearing loss prevalence of 22.3%. These figures are alarming, especially given how ingrained headphone use has become in daily life.

The ramifications of early-onset hearing loss go far beyond damaged ears. It can also jeopardize your mental health. Hearing loss in youth can set off a chain reaction, leading to social isolation and depression. Over time, it can also escalate and jeopardise your relationships. Ill-fitting headphones add to the woes, causing pain that extends from the inner ear to the jaws and top of the head. They can also lead to ear infections, which eventually hamper cognitive functions.

Protecting hearing and brain health requires a shift in listening habits. Experts recommend keeping the volume below 60 per cent and limiting usage to 60 minutes per day. Investing in noise-cancelling headphones can also help reduce the need to crank up the volume in noisy environments.

Norovirus, often called the “stomach flu” or “winter vomiting illness,” is currently circulating in California and across the United States. Health experts say proper cleaning and disinfecting can slow its spread. These precautions matter because norovirus is extremely contagious and there is no specific treatment for it, according to the Centers for Disease Control and Prevention.

Between August 1 and November 13, health officials recorded 153 norovirus outbreaks across 14 states. The CDC defines an outbreak as two or more similar illnesses linked to suspected or lab-confirmed norovirus cases. Although California is not among the states reporting outbreaks, CDC data shows a noticeable rise in positive norovirus tests throughout November across the western US.

What Is Norovirus?

Norovirus is described as a “highly contagious” virus that causes vomiting, diarrhea, and stomach cramps, according to the California Department of Public Health. It leads to acute gastroenteritis, which means inflammation of the stomach or intestines, and affects people of all ages, the CDC said.

Despite its nickname, norovirus has nothing to do with influenza. The flu is caused by the influenza virus, not norovirus, the agency clarified.

Winter Vomiting Disease: How Does The Stomach Bug Spread?

Norovirus spreads easily from person to person, especially while someone is actively sick, according to the California Department of Public Health. Symptoms usually last one to three days, but a person can still spread the virus for up to two days after they start feeling better.

The virus is present in vomit and stool and can spray into the air or settle on nearby surfaces. It can survive for weeks on uncleaned items such as countertops, phones, and doorknobs, the department said.

“You can get sick after touching or caring for someone who is sick, or after touching or eating something that is contaminated,” the department noted.

Norovirus spreads quickly in crowded or enclosed settings, including schools, child care facilities, hospitals, nursing homes, jails, and cruise ships.

According to state and federal health officials, the most common ways people catch norovirus include:

• Touching, caring for, or sharing food with someone who has norovirus
• Eating or drinking contaminated food or beverages, including undercooked shellfish like oysters
• Touching a contaminated surface and then touching your mouth before washing your hands
• Sharing a toilet or bathroom with someone who is sick
• Swallowing contaminated water, including water from swimming pools or recreational areas
• Cleaning up vomit or diarrhea without protective gear, such as gloves or a face mask

Do You Need To Disinfect After Norovirus?

“If you or someone in your household has norovirus, it’s important to clean and disinfect areas where vomiting or diarrhea occurred,” the California Department of Public Health advised. Cleaning with soap and water removes germs, while disinfecting kills those that remain.

You can use commercial disinfectants, but it’s important to read the label and make sure norovirus is listed among the germs it targets. You can also check the Environmental Protection Agency’s registration number and confirm it appears on the EPA’s List G, which includes products proven effective against norovirus.

Another option is making a bleach solution at home. The US Department of Agriculture recommends mixing 5 to 25 tablespoons of household bleach with one gallon of water. This solution should be used only on hard or nonporous surfaces and applied with a spray bottle or disposable mop, sponge, or paper towel. Let it sit for about five minutes before wiping it away.

The USDA also advises paying close attention to frequently touched items such as doorknobs, handles, and remote controls. Many disinfectant wipes do not fully kill norovirus, the agency warned.

How To Disinfect After Norovirus?

The CDC recommends wearing rubber or disposable gloves while cleaning. Use paper towels to wipe the affected area completely, then place the towels in a plastic trash bag. The California Department of Public Health also suggests wearing a face mask.

After disinfecting, clean the area again with soap and water, the CDC said. Keep in mind that vomit can aerosolize the virus, meaning surfaces several feet away may also be contaminated, according to the USDA.

Once you’re done, throw away the gloves and mask, then take out the trash, the California Department of Public Health advised.

Millions of people across the UK who take certain everyday medicines are being warned by the NHS to steer clear of a specific fruit. Health officials say combining this fruit or its juice with some medications can trigger serious reactions and unexpected side effects. The advice applies to patients prescribed some of the most commonly used drugs in the country, including certain statins, amlodipine, and medicines for anxiety. Statins, in particular, are widely prescribed to help reduce levels of “bad” LDL cholesterol in the blood.

Why Statins Are Commonly Prescribed?

Statins work by limiting how much cholesterol the liver makes. This helps slow down the build-up of fatty deposits inside the arteries, which in turn lowers the risk of heart attacks and strokes. Doctors prescribe statins both to manage high cholesterol and to prevent future heart-related problems. For most people, they are taken daily as tablets and are often part of long-term treatment.

What Does Amlodipine Do?

Amlodipine, commonly sold under the brand name Istin, belongs to a group of medicines known as calcium channel blockers. It is mainly used to treat high blood pressure. For people with hypertension, amlodipine can reduce strain on the heart and lower the risk of serious complications such as heart disease, heart attacks, and strokes.

NHS Warning On Statins Or Amlodipine

Patients taking certain forms of amlodipine, particularly calcium channel blockers, are advised not to consume grapefruit. The NHS website clearly states: “Do not take amlodipine with grapefruit juice.”

The reason lies in how grapefruit affects the body. It interferes with enzymes and transport proteins in the gut, such as CYP3A4 and P-gp, which normally help break down medicines and control how much enters the bloodstream. When these processes are blocked, higher-than-intended amounts of the drug can build up in the body, increasing the risk of side effects.

What Patients Should Keep In Mind

Not every medicine reacts the same way to grapefruit juice, which is why doctors advise checking before making changes. Always speak to your GP or pharmacist, read the information leaflet that comes with your medicine, and look out for any warnings related to grapefruit.

It is also important to understand that simply spacing the fruit and the medicine apart is not enough. In most cases, grapefruit should be avoided entirely for as long as you are on the medication, unless your doctor says otherwise. Patients are also encouraged to be cautious with other citrus fruits, such as Seville oranges, pomelos, and limes, as they can have similar effects on how medicines work.

What To Do If You’ve Already Consumed It?

If you have eaten grapefruit or had its juice while taking statins, amlodipine, or anti-anxiety medication, there is no need to panic. In many cases, a single exposure does not lead to serious harm, but it is important to stay alert. Pay attention to how your body feels over the next day or two, especially if you notice symptoms such as dizziness, muscle pain, unusual tiredness, nausea, flushing, or a sudden drop in blood pressure.

Do not stop taking your medication on your own. Skipping doses or stopping treatment abruptly can be risky, particularly for heart and blood pressure medicines. Instead, make a note of what you consumed and when, and contact your GP or pharmacist for advice. They can tell you whether any action is needed based on the specific drug, dose, and your overall health.

During the festive months, overindulgence in celebrations can trigger holiday heart syndrome (HHS), a potentially serious yet largely preventable set of heart-related symptoms that tend to rise during this time of year. Most people recover within a day, but HHS can occasionally lead to stroke, heart attack, or other serious complications, according to the Cleveland Clinic. As the holiday season approaches, let’s explore what holiday heart syndrome is, its symptoms, and how to prevent it.

What Is Holiday Heart Syndrome?

First identified by a US physician in 1978, holiday heart syndrome describes irregular heartbeats that occur after binge drinking during the festive season. Research from the University of South Australia shows that alcohol consumption increases by 70 per cent in December compared to other months, while iSelect data predicts Australians may consume around 58 million standard drinks per day during the month. With numbers like these, some caution is warranted.

Atrial fibrillation (AFib) is the specific irregular heartbeat seen in HHS. It occurs when the heart’s upper chambers contract or quiver in a chaotic pattern, which can cause blood to pool in the atrium and form clots. If these clots enter the bloodstream, they can travel to the brain and trigger a stroke.

What Are the Symptoms of Holiday Heart?

Symptoms can include fatigue, dizziness, shortness of breath, anxiety, weakness, confusion, sweating, faintness, unusual tiredness during exercise, rapid or irregular heartbeat, and sensations like fluttering, thumping, pressure, or chest pain.

Dr Mariann R. Piano, Nancy and Hilliard Travis Professor of Nursing at Vanderbilt University School of Nursing, warns, “The scary thing is that people may not notice any symptoms, which makes it a particularly dangerous arrhythmia.”

How Can Drinking Lead to AFib?

Researchers are still investigating exactly how alcohol triggers AFib and how much intake increases the risk. A 2020 study found that people who usually drank at least 10 alcoholic beverages a week lowered their risk of holiday heart syndrome by reducing alcohol consumption. Another study confirmed that eliminating alcohol significantly decreases the chances of developing AFib.

How To Try to Avoid Holiday Heart Syndrome

The Australian Alcohol Guidelines recommend that healthy adults limit alcohol to no more than 10 standard drinks per week to reduce risk.

Experts like Kistler suggest that people with existing heart arrhythmias either abstain or stick to “up to three standard drinks a week.” Drinking mindfully, reducing overall consumption, and staying well hydrated can also help protect your heart.

Tips To Keep Your Heart Healthy During Holidays

• Eat smaller, balanced meals and avoid heavy late-night feasts.
• Limit alcohol intake and stay hydrated.
• Continue regular medications without interruption.
• Stay warm and avoid sudden exposure to cold temperatures.
• Maintain light physical activity and avoid strenuous exertion in the early morning.
• Manage stress by taking breaks, sleeping adequately, and avoiding overexertion during travel or celebrations.
• Seek medical help immediately if you experience chest discomfort, unusual fatigue, breathlessness, or palpitations.
