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.

World Zoonoses Day is being observed today amid growing concerns over the rising threat of zoonotic diseases such as Ebola, Marburg and Nipah. More than 60% of human pathogens are zoonotic, while nearly 75% of emerging infectious diseases originate in animals.

According to the International Society for Infectious Diseases (ISID), spillover events—where pathogens jump from animals to humans—have tripled since the 1980s, fueled by deforestation, wildlife trade, industrial farming and climate change.

In an interview with HealthandMe, Dr Nivedita Gupta, Scientist and Head of the Communicable Diseases Division at the Indian Council of Medical Research (ICMR), outlined the key measures policymakers should prioritize to reduce the risk of future pandemics and strengthen global health security.

Dr Gupta stressed that preventing the next pandemic requires a proactive approach built on integrated surveillance, coordinated data sharing, community participation and stronger indigenous research and development.

Strengthening Surveillance

According to Dr Gupta, the first priority should be strengthening surveillance across all sectors—across humans, animals and the environment.

"I think first part is that surveillance should be strengthened in all domains, whether it is human surveillance, animal surveillance, wildlife surveillance, as well as environmental surveillance. So, we really need to do integrated surveillance and strengthen all aspects."

She said early detection is critical to identifying emerging pathogens before they become larger public health threats.

"Unless we are able to detect what is happening at various interfaces, we will never come to know that a certain pathogen or a disease is emerging."

Human And Animal Health Data

The second major priority, she said, is ensuring that surveillance data across sectors is connected.

"If I'm seeing unusual bird or animal deaths, if I'm sitting in human sector, I should also know about it and I should be able to act very timely to understand whether there are any implications on humans and vice versa."

Dr Gupta said data from human, animal and wildlife surveillance systems should "talk to each other" to detect zoonotic diseases at an early stage.

She also highlighted the importance of recognizing reverse zoonosis.

"It's not only that we get infections from animals, birds, and wildlife, but animals also get infected from humans. So, that is known as reverse zoonosis. So, it is both ways."

According to her, anything occurring in the human sector should raise equal alarm in the non-human sectors, and vice versa.

Communities Should Become 'Eyes And Ears'

Dr Gupta said community participation is another critical pillar of pandemic preparedness.

"I think we really need massive community sensitization. And community should be our eyes and ears because there are many people who live in remote areas, who live in forest fringes, and they might be seeing many unusual things happening like sudden deaths among animals, carcasses."

She noted that there is currently no system to help people recognize unusual events or report them to the authorities.

"I think those systems wherein our community can be our eyes and ears is something that we really need to develop in our country so that any unusual occurrence which happens within domestic animals or forest fringes or in birds or poultry farms can be immediately reported to the relevant authorities and a timely action can be taken."

Strengthen Indigenous R&D

Dr Gupta also stressed the need to strengthen the research ecosystem and also work in collaboration with the industry. She said academia and industry currently work in separate silos, making it difficult to rapidly translate research into products.

It is important "to align academia and industry so that industry gets ready-made products which align with the priorities of the country."

The expert added that stronger industry-academia partnerships would help develop products that serve national priorities.

What Can Individuals Do?

On the role of citizens, Dr Gupta said individuals can contribute by reporting unusual events involving animals or wildlife.

"If I see any unusual thing happening in my domestic settings or around me or if I'm a person residing at forest fringes or in bird sanctuaries, I see unusual deaths, I should be able to report them."

However, she pointed out that governments must first establish a reporting mechanism. "So, currently, even if I want to report today, I don't know where to go."

She said people need to be informed about what constitutes an unusual event and how to report it.

"I think that community sensitization telling them what is unusual, what has to be taken up with a pinch of salt, what has to be reported to the authorities really needs to be told to the people of the country so that they start reporting and they become our sentinels."

Here’s how one can stay safe after getting exposed to floodwater:

Precautionary Measures After Walking Through Floodwater

HealthandMe spoke to Dr. Murtaza S Bagwala, Head of Emergency Medical Services, Saifee Hospital, Mumbai, about how to keep infections at bay after coming in contact with filthy floodwater.

Pay Close Attention To Your Feet And Legs, Even If They Don't Hurt

When you are in floodwater, there may be sharp objects like broken glass, nails, stones and metal debris around you. You are more likely to come in contact with these objects unintentionally.

Dr. Bagwala recommends, “Small cuts, blisters, or punctures may not be noticed but can lead to infection if bacteria get into the skin. If you see any injury, clean it well, brush on antiseptics and consult a doctor for advice if the wound is deep or dirty.”

Don't Overlook Body Aches Or Fever In The Following Days

As the risk of contracting infections is high during monsoon, do not neglect if you develop flu-like symptoms after coming in contact with contaminated floodwater. The expert warns against dangerous monsoon infections like leptospirosis.

He says, “After contact with water contaminated with the urine of an infected animal (usually a rodent), the early symptoms of leptospirosis may include fever, severe muscle pain, headache, vomiting, chills, or redness of the eyes. The symptoms are very similar to those of a viral disease, so prompt medical evaluation is crucial to avoid complications, such as kidney, liver, or lung involvement.”

Don't Ignore Skin Changes

The doctor also says that if your skin’s colour or texture changes after getting exposed to floodwater, do not ignore it. He says that if the area around the feet or legs becomes red, swollen, painful, warm, discharges pus or the itching persists, it should be treated immediately.

These can be signs of bacterial or fungal infections that need to be treated, especially in individuals with diabetes, poor blood flow, or impaired immune function.

Determine If Your Tetanus Shots Are Updated

As you can get cuts and bruises after walking through floodwater, it is important to stay on top of your tetanus shots.

The expert advises, “Seek health care advice if you have a cut or puncture wound, particularly from a sharp object that was submerged in the water, while walking through the water. Early management of wounds can help avoid complications."

Take Precautions When Eating Or Drinking After Exposure

You are also at risk of contracting gastrointestinal infections after coming in contact with floodwater. Contaminated water may enter your mouth and lead to stomach and intestinal infections or may contact food and lead to food poisoning.

Prevent diarrhoea, vomiting and dehydration by drinking only clean, safe water, eating only freshly prepared food and practicing good hand hygiene before eating.

Why Diabetic Foot Care Deserves As Much Attention As Blood Sugar Management

Updated Jul 6, 2026 | 01:00 PM IST

SummaryMost patients presenting with advanced diabetic foot disease describe a history of minor symptoms that were attributed to something else, ignored, or left unaddressed because they were painless.

India has approximately 101 million people living with diabetes, one of the largest such populations in the world. Blood sugar levels, HbA1c targets, and medication compliance tend to dominate the clinical conversation around the condition. What receives considerably less attention, from both doctors and patients, is what diabetes does to the feet, and what the consequences of that neglect look like over time.

How Diabetic Foot Ulcers Develop

Diabetic foot ulcers develop when nerve damage caused by prolonged high blood sugar, referred to as diabetic neuropathy, reduces sensation in the feet. A small cut, blister, or pressure sore that a person without neuropathy would notice and address goes unfelt. In the absence of pain as a warning signal, the injury progresses. Infection sets in. By the time the patient presents for medical attention, the wound has often reached a stage where conservative management is no longer sufficient.

The High Cost of Delayed Treatment

The clinical outcomes associated with delayed presentation are sobering. A 2024 study published in Diabetes and Metabolic Syndrome, drawing on real-world data from a tertiary care facility in India, found that amputation was required in 43.4 percent of diabetic foot ulcer patients. Ten-year mortality among those who underwent amputation reached 30.9 percent, compared to 24.5 percent among those who achieved primary healing.

A 2025 cross-sectional study published in Cureus found a significant disparity in mortality rates between individuals with diabetic foot ulcers and those with diabetes alone, at 231 deaths per 1,000 person-years compared to 182. Globally, 18.6 million individuals develop diabetic foot ulcers annually.

Prevention Requires Daily Foot Care

The gap between the clinical evidence on diabetic foot complications and the attention the condition receives in routine diabetes management is where the preventable harm accumulates. Most patients presenting with advanced diabetic foot disease describe a history of minor symptoms that were attributed to something else, ignored, or left unaddressed because they were painless.

Regular foot inspection, appropriate footwear, avoidance of barefoot walking, and early medical review of even minor foot injuries are the practices that interrupt this progression before it reaches the point of irreversibility. Dedicated foot care clinics are built around exactly this philosophy, bringing together the multidisciplinary expertise needed to catch complications early and treat them before the window for limb salvage closes.

Why Multidisciplinary Care Matters

Eastern India carries a significant share of this burden, with patients across West Bengal, Bihar, Odisha, Jharkhand, and the Northeast frequently facing limited access to the multidisciplinary care that diabetic foot management requires. Diabetologists, vascular specialists, wound care experts, reconstructive surgeons, and rehabilitation teams working in coordination produce outcomes that sequential, single-specialty care cannot consistently achieve. Where such integrated care is available and accessed early, limb salvage rates improve, and amputations are reduced.

The Ministry of Health and Family Welfare’s recent advisory on diabetic foot care reinforces that foot health in diabetes management warrants systematic attention, not as an afterthought to glycemic control, but alongside it.
