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.

California made it news for a disease that has no vaccination. This is the human metapneumovirus or the HMPV. While some of the symptoms of this virus are similar to that of any common cold or influenza like cough, fever, nasal congestion or shortness of breath, there are several symptoms that are unique to the disease.
Unlike mild common colds, HMPV often presents with a high-grade fever, particularly in children. Some of the other symptoms also include persistent coughing, including dry or productive and may persist for a long duration.
Furthermore, it could cause wheezing, difficulty in breathing, which could also lead to severe lower respiratory tract illness like bronchiolitis or pneumonia. In children and older adults, it could also cause severe or often fatal bronchiolitis or rapid-onset pneumonia.
In infants, it could also exhibit irritability, poor feeding, or dehydration.
Other symptoms, which could resemble common cold like symptoms are:
As per the public database WasterwaterScan Dashboard, high levels of HMPV were detected across Northern California cities. The highest levels were reported in Redwood City, whereas elevated levels were found in San Francisco Bay Area and Napa's Wine Country. What's more dangerous is that this virus is without a vaccine.
The good news is that in other parts of country HMPV remains lower. However, the Centers for Disease Control and Prevention (CDC) noted that data from October 2025 shows the cases are trending up, especially during winter and spring.

Dr. Matthew Binnicker, director of the Clinical Virology Laboratory at Mayo Clinic, as reported by The Independent said, "In the late winter, early spring, it can account for five percent to 10 percent of all the respiratory infections that we diagnose in the United States. So it's definitely out there." Experts explain that other viruses like HMPV or influenza get a chance when COVID is quieter.
HMPV was first discovered in 2001 and is part of the Pneumoviridae family along with the Respiratory syncytial virus (RSV).
HMPV most likely spreads from an infected person to others through:
In the US, HMPV circulates in predictable patterns each year, typically beginning in winter and lasting through spring.
People at risk include:
"The HMPV is not deadly, and there is no evidence of mortality or a severe transmission rate," former Indian Council of Medical Research (ICMR) scientist, Dr. Raman Gangakhedkar, told IANS, during the virus's outbreak in India in 2025.
“The virus may cause pneumonitis-like illness, but the mortality rates are almost unknown so far. HMPV has a global prevalence of about 4 per cent,” he added.

Smoking has been long recognized as one of the worst habits a person can have, and Dr Jeremy London agrees with this statement. Dr. London, a cardiovascular surgeon, in a recent interview with Mel Robbins revealed that his number one advice as a heart doctor is to avoid smoking.
“I cannot come up with one single thing that does as much damage to every organ in the body as smoking cigarettes. And look, it's incredibly addictive and I know that and I pass no judgment because I know how difficult it is.”
He explained that in his practice he has dealt with chronic smokers for years and still believed that it is the single most dangerous thing one can do to themselves.

Emphasizing how this one habit affects all organs in our body, Dr London mentioned the well-known link between lung cancer and smoking.
However, there are many more chronic diseases associated with the rest of the body that can develop due to smoking apart from lung conditions, according to the American Lung Association.
Here is what you should keep an eye out for:

Fasting for three hours before bed can significantly improve heart health and reduce the risk of coronary artery disease (CAD) as well as other chronic conditions, an Arteriosclerosis, Thrombosis, and Vascular Biology study suggests.
While many believe that diet plans such as intermittent fasting or time-restricted eating can help reduce their weight, researchers at Northwestern University have found that not eating three hours before going to sleep can reduce overnight blood pressure by nearly four percent, heart rate by five percent and strengthen overall heart rhythms.
This can help reduce overall strain on the heart which lowers risks for conditions like hypertension and CAD. Additionally, the scientists also discovered a drop in blood sugar levels, improved glucose tolerance and insulin sensitivity.
Participants who underwent glucose tests also showed better insulin release which tend to stabilize during the day. Additionally, an improved heart rate also lowered nighttime cortisol, which helped in metabolic balance.
Dr. Phyllis Zee, director of the Center for Circadian and Sleep Medicine and chief of sleep medicine in the department of neurology at Feinberg and corresponding author said of the results: "It's not only how much and what you eat, but also when you eat relative to sleep that is important for the physiological benefits of time-restricted eating."
The study authors also noted: "Extending overnight fasting duration by three hours in alignment with sleep improved cardiometabolic health in middle-aged/older adults by strengthening coordination between circadian- and sleep-regulated autonomic and metabolic activity.
"This sleep-aligned time-restricted eating approach represents a novel, accessible lifestyle intervention with promising potential for improving cardiometabolic function."
Despite being as a common heart disease, coronary artery disease (CAD) develops over years and has no clear signs and symptoms apart from a heart attack. The illness begins due to a buildup of fats, cholesterol and other substances known as plaque in and on the artery walls.
Over time, this can cause narrowing or blockage of the coronary arteries and block the supply of oxygen-rich blood to heart which can lead chest pain (angina), shortness of breath and ultimately, heart attacks.
Typically, those above the age of 45, having a biological family member with heart disease, lack of sleep, smoking, consuming saturated fats along with other autoimmune diseases such as lupus and rheumatoid arthritis can increase the risk of developing CAD.
Treatment options may include medicines and surgery. Eating a nutritious diet, getting regular exercise and not smoking can help also prevent CAD and the conditions that can cause it.
Nearly one in 10 Indian adults suffer from CAD and about two million people die from the disease annually. Apart from this, about 18 to 20 million American adults aged 20 and older are also affected about the disease.
One in seven stroke patients in India are young adults aged below 45 years, with hypertension leading as the major risk factor, according to a study by the Indian Council of Medical Research (ICMR).
The Global Burden of Disease Study 2021 identified hypertension, air pollution, tobacco smoking, high cholesterol, increased salt intake, and diabetes as the leading risk factors of stroke.
Incidence of stroke is increasing significantly in low- and middle-income countries (LMICs), especially in India, due to population growth, aging, and greater exposure to risk factors.
