You won't believe this overlooked cause can be behind heart failure; new study unveils shocking results
hearing impairment
often results in an increased risk of
heart failure
in human beings. According to the study,
psychological distress
caused by hearing impairment plays a 'notable' role in developing problems with the heart. Experts in China analyzed data from the UK Biobank, studying 164,431 people who took hearing tests designed to determine hearing ability for the research. Out of all participants, about 160,062 didn't use
hearing aids
.
Heart failure happens when the heart cannot pump blood effectively, leading to symptoms like fatigue, shortness of breath, and swelling in the legs and ankles. According to the Independent, test participants were split into three groups based on how they performed in a digit triplet test (DTT), which checks for hearing issues by using random digit combinations against the background noise.

What did the research find
Following the study, the researchers discovered that those who had a higher speech reception threshold (SRT), meaning they required louder speech to understand words, had an increased risk of heart failure. 'Compared with those with normal hearing, participants with insufficient hearing, poor hearing, or hearing aid use had higher heart failure risks,' researchers were quoted by The Independent as saying.
Live Events
Among people who didn't use hearing aids, high SRT levels were also linked to psychological distress, social isolation, and neuroticism. 'We have been the first to demonstrate that poor hearing ability is significantly associated with a higher risk of incident heart failure in the general population,' the researchers further stated.
'Psychological factors, especially psychological distress, play a significant mediating role in this association. If further confirmed, hearing impairment may be a potential risk factor or marker for incident heart failure in the general population, highlighting the importance of integrating hearing health assessments into broader cardiovascular risk evaluation frameworks. Moreover, strengthening psychological intervention in people with hearing impairment may be an important path and strategy to reduce the risk of heart failure,' they continued.

5 early warning signs of leaky gut syndrome that one should not ignore
Human bodies are a complex system of nerves, tissues, and cells. What most of us don't realise is how intricately the system works. Each body part, nerve, and tissue is interconnected, and exclusively inside our bellies. We have an extensive intestinal lining covering more than 4,000 square feet of surface area. When our gut is working properly, it forms sort of a protective layer of tissues that controls what gets absorbed in the bloodstream, while if it is not working properly, an unhealthy gut may cause large holes in the gut lining that allows partially digested food and toxins to penetrate the tissues beneath it, triggering chronic inflammation and severe changes in gut's normal bacteria. Surprisingly, the research world is buzzing with studies showing that several modifications in intestinal bacteria and inflammation may play a major role in the development of several chronic issues and diseases, including leaky gut, which is a syndrome that is recognized as a 'presumed condition'. It is founded on the idea of relative intestinal permeability What is leaky gut Leaky gut, commonly defined as increased intestinal permeability, occurs when the lining of the small intestine is destroyed, allowing undigested food particles, toxins, and germs to 'leak": through the intestines and into the bloodstream. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like They were so beautiful before; look at them now; number 10 will Surprise you Undo Although this is a syndrome that is hypothetically recognized and is not currently well-studied as a medical diagnosis. It is severely based on the concept that increased permeability occurs in some gastrointestinal diseases. Intestinal permeability and leaky gut syndrome Intestinal permeability is the property that allows solute and fluid exchange between the lumen and tissues. Conversely, intestinal barrier function refers to the ability of the mucosa and extracellular barrier components, such as mucus, to prevent this exchange. A critical function of the intestinal epithelium is to form a barrier that prevents the permeation of pro-inflammatory molecules, such as pathogens, toxins, and antigens, from the luminal environment into the mucosal tissues and circulatory system. As stated by researchers in their study 'Intestinal Permeability Regulation by Tight Junction: Implication on Inflammatory Bowel Diseases,' conducted back in 2015. While its evidence suggests that it is related to the Irritable bowel syndrome (IBS), it contributes to several other diseases as well, such as Crohn's disease, diabetes, chronic liver disease, celiac disease, etc. Potential warning signs of leaky gut syndrome Most of the warning signs of the leaky gut syndrome mimic the symptoms of other health conditions and that is why, without a proper diagnosis, it is impossible to say someone has it. (source: Cleveland clinc) Its symptoms include: Diarrhea, constipation, and bloating These digestive issues might be an indication that something is going on with your digestive system, and your gut health is compromised. The damaged intestinal lining affects nutrient absorption and causes digestive discomfort. Unhealthy diet Diets high in refined sugars, gluten, processed foods, and artificial additives can irritate the gut lining. In addition, nutritional deficiencies in zinc, vitamin A, and vitamin D can also weaken the intestinal barrier. Chronic inflammation Inflammation is responsible for a lot of things that happen in our bodies. Conditions like inflammatory bowel disease (IBD), Crohn's disease, and ulcerative colitis are caused by inflammation that can also contribute to intestinal permeability. Acne, Psoriasis, and other skin conditions Acne and other skin conditions are the immune system's reaction to the toxins present in our bodies. It is not difficult to conclude that these toxins can be the byproduct of leaky gut. Food sensitivities Some of the most common offenders are gluten, dairy, and certain food grains. These can trigger an inflammatory reaction in sensitive people, usually manifesting itself as bloating, fatigue and inflammation.

Why are experts warning against Benadryl, the common cough syrup?
Benadryl, a medicine many households have relied on for decades, is now under serious scrutiny from health experts. Known for treating allergies, cough, cold, and even used as a sleep aid, Benadryl (which contains the drug diphenhydramine) is being called outdated and potentially risky. A new review published in February 2025 by allergy experts from Johns Hopkins University and the University of California, San Diego, is urging for the drug to be pulled from over-the-counter (OTC) and prescription markets in the U.S. due to its side effects and availability of safer alternatives. Here's why medical professionals are now advising people to think twice before reaching for this common medication. Outdated and risky, say experts Diphenhydramine was approved back in 1946 as a first-generation antihistamine. While it does help manage allergy symptoms like sneezing and itching, experts argue it affects more than just the allergy-related parts of the brain. It can also cause sedation, dizziness, confusion, and even dangerous heart issues. According to the review, Benadryl poses more harm than newer antihistamines, especially for young children and older adults. The drug can stay in the body for up to 18 hours in seniors, leading to ongoing drowsiness and increased risk of falls. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like No annual fees for life UnionBank Credit Card Apply Now Undo In children, misuse can cause agitation, extreme sedation, or even coma and death in rare cases. Not the best choice for allergic reactions Despite its popularity, some doctors say Benadryl isn't the best option during severe allergic reactions. Dr. Anna Wolfson, an allergist at Massachusetts General Hospital, told CNN, 'If someone has an allergic reaction to a food, people will say, 'Don't worry, I have diphenhydramine in my purse,' and I would say, 'Really, epinephrine is the first-line treatment for food allergies.'' Benadryl affects acetylcholine, a brain chemical involved in memory and learning. A 2015 study in JAMA Internal Medicine found that those who used drugs that block acetylcholine, like Benadryl, had a 54% higher risk of dementia and a 63% greater chance of developing Alzheimer's. The World Allergy Organization Journal also linked diphenhydramine to poor academic outcomes, citing major declines in attention, memory, and processing speed. Not safe for children Doctors are also raising concerns about how diphenhydramine is being used in children. Dr. Alyssa Kuban, a pediatrician and associate medical director at Texas Children's Pediatrics, told CNN: 'I see some families use diphenhydramine when the child has a cold or upper respiratory infection, thinking it will help with the congestion and help them to sleep better at night. This is not effective for cold symptoms, nor is it very safe. ' Source: Getty Images Experts say that loratadine and cetirizine are safer for children over 6 months, while saline drops and suction are better for infants. Experts also pointed to social media risks. The drug was involved in dangerous viral trends like the "Benadryl Challenge," which led to child hospitalizations and even fatalities. What should you do? Although Benadryl is found in over 300 products and still widely used, experts are clear: safer alternatives exist. Second-generation antihistamines like cetirizine and loratadine offer similar relief with fewer side effects and longer-lasting results. These newer medications don't cause the same level of sedation or cognitive impairment. The authors of the February 2024 review concluded: 'In the past, it has been a useful medication that has helped millions of patients; however, its current therapeutic ratio is matched or exceeded by second-generation antihistamines, especially due to their markedly reduced adverse reactions. It is time to say a final goodbye to diphenhydramine, a public health hazard.'

7 vs 9 hours of sleep: What's the ideal amount and why it might not be what you think
We've all heard it: 'Get 8 hours of sleep.' But is that really the magic number? For years, health advice has lumped 7 to 9 hours into one big category of 'normal,' leaving most of us guessing where we fall on the sleep scale. Some swear by long weekend lie-ins, while others feel sharp and energised after just seven hours. So which is actually better: 7 or 9 hours of sleep? Can too much sleep be just as risky as too little? And what does science really say about the right amount of rest for your body and brain? New research reveals that seven hours may be the sweet spot for most adults, not just for feeling fresh in the morning, but for long-term health, mental clarity, emotional balance, and even how long you live. Let's break down the science, bust a few myths, and help you figure out your own ideal sleep rhythm. Why seven hours may be the golden number A large study published in Nature Aging examined data from nearly 500,000 adults aged 38 to 73 and uncovered a clear pattern: those who consistently slept for seven hours per night performed significantly better in tests measuring cognitive function, memory, and mental health. Compared to individuals who slept either less or more, the seven-hour sleepers showed sharper attention, quicker processing speed, and more stable moods. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Brain tumor has left my son feeling miserable; please help! Donate For Health Donate Now In contrast, both short and long sleep durations were associated with reduced problem-solving skills, poorer memory recall, and higher levels of anxiety and depression. The findings suggest that even an extra hour or two of sleep beyond the seven-hour mark may not offer added benefits and could actually be linked to declines in brain function and emotional wellbeing. Even the Journal of Clinical Sleep Medicine recommends at least seven hours for adults aged 18 to 60. Consistently getting less than that has been linked to a higher risk of obesity, stroke, Type 2 diabetes, depression, heart disease, and weakened immunity. So why not nine? That's where it gets interesting. Is sleeping nine hours harmful? Not necessarily but it can be a red flag. While an occasional long sleep is fine (like after travel or illness), regularly needing more than nine hours may point to poor sleep quality or an underlying health issue. Studies have shown that long sleepers are at greater risk for: Brain fog and slower mental processing Higher levels of inflammation in the body Mood disorders, especially depression Increased mortality risk in some long-term studies In short: more sleep doesn't automatically mean better health. If you sleep longer and still feel tired, it might be time to look at your sleep hygiene or consult a doctor. What happens if you sleep less than seven? If you're used to burning the midnight oil or waking up early with only 5–6 hours of sleep, your body might be silently suffering, even if you don't feel it right away. Too little sleep, especially over time, can lead to: Weight gain and metabolic issues Poor focus, mood swings, and memory lapses Weakened immune system Higher risk of heart disease and diabetes And no, 'catching up' on the weekend doesn't fully reverse the effects of regular sleep loss. Even if you're clocking in your seven to nine hours of sleep, irregular sleep timing like sleeping at different hours every night or shifting your bedtime drastically on weekends can still wreak havoc on your health. Your body's internal clock, or circadian rhythm, thrives on routine. When that rhythm is disrupted, even the right amount of sleep may not be enough to keep your system in balance. Recent large-scale research has shown that inconsistent sleep and wake times can raise the risk of developing up to 172 different health conditions, ranging from liver damage and metabolic disorders to obesity, type 2 diabetes, and cardiovascular disease. What's more alarming is that even people who technically get enough sleep, say seven or eight hours a night, face a 26% higher risk of heart attacks and strokes if their sleep pattern is erratic. In short, consistency matters just as much as duration, and maintaining a steady sleep schedule could be one of the most underrated health habits you can build. Both 7 and 9 hours can fall into the healthy sleep range but they're not created equal. For most adults, seven hours of consistent, good-quality sleep offers the best mix of mental clarity, physical recovery, and long-term health protection. Instead of just counting hours, pay attention to how you feel, how consistently you sleep, and how well your body performs during the day. Because when it comes to sleep, it's not just about more, it's about smarter. Also read| Why women suffer more from migraines and why doctors often ignore their pain
