Doctors And Scientists Are Revealing Things People Don't Realize Are Wildly Bad For Their Health
We recently asked doctors, scientists, and other medical professionals of the BuzzFeed Community to tell us things people don't realize are very bad for their health, or "bad" habits people often downplay that could be detrimental. Their answers were incredibly eye-opening — and I can't lie, some of them were even scary. Here's what they had to say:
Note: Some responses were pulled from this Reddit thread by u/prettiestburner.
1."If you snore, get a sleep study. Sleep apnea kills. It's not just something that annoys everyone within a five-block radius; it can KILL YOU. Why? Hypertension, excessive daytime sleepiness with more accidents, depression, anxiety...and hypertension leads to heart, kidney, and other small vessel disease that leads to organ failure and strokes."
—nyc4ever
"Untreated sleep apnea can cause excessive daytime sleepiness that might cause a car accident, high blood pressure, and even heart failure over time. If you snore or feel tired all the time, you should mention this to your provider."
—Anonymous, 63, Oregon
2."Taking OTC products with the same ingredients, such as a cough syrup and cold medication. They both have Tylenol. You can easily end up in liver failure."
—Anonymous
3."As if it needs to be said, but excessive alcohol drinking. We all know what it does to you, but I'll give it a spin that I learned in a decade in the ICU: Dying from alcohol is just about the worst way to die. No one thinks about dying slowly, constantly seizing when they're on a bender. No one thinks about your entire body turning yellow when they're tying one on after work."
"No one thinks about your body swelling up to the point of being unrecognizable when they are downing a 12-pack every night."
—Anonymous, 45, Kentucky
"I'm an internal medicine doc. Alcohol excess has several consequences: decompensated cirrhosis with encephalopathy and ascites, or alcoholic hepatitis. Also, alcoholic cardiomyopathy. It can also lead to early onset alcohol-induced dementia and alcohol-related brain injury — more on the frontal lobe, so more impulse control and other executive functioning problems than standard Alzheimer's. There's also Korsakoff's psychosis."
—noobREDUX
4."Biting your nails!!! This brings so much bacteria into your system, can chip and harm your teeth, and in extreme cases, can lead to stomach pain and blockages."
—Anonymous, 26, Pennsylvania
5."Secondhand smoke. You get all the negatives of smoking cigarettes, just at a lower concentration. But over time, it adds up. I've seen people with significant lung disease because they lived with smokers for decades!"
—Anonymous
6."Hands down, the worst thing you can do to your body is smoking. The pictures on those anti-tobacco ads aren't nearly gruesome enough to show you how much it affects the body. My colleagues and I see SO many diseases and internal injuries that are caused by smoking: internal bleeding, lung cancers, loss of appetite, tremors, etc."
"There are so many things that can go wrong if you smoke long-term, not to mention the environmental concerns. Please, look at some stats and STOP SMOKING."
—Anonymous

7."Skipping the floss portion of oral health care. The bacteria not only can lead to bleeding gums and potentially tooth loss, but the same bacteria can also enter the bloodstream. If that bacteria enters the bloodstream, it can lead to major heart problems or possibly dementia."
—Anonymous, 35, Pennsylvania
8."Being underweight is just as unhealthy, if not worse, than being overweight. When you're underweight, you're more likely to have a severe injury than average or overweight people, and recovery takes longer. You're also more likely to get sick more often and feel worse when you do get sick because your body has fewer resources to fight off illnesses like respiratory infections. Plus, tiredness and fatigue are huge problems for people who are underweight."
"Lots of people give overweight people a hard time out of 'concern for their health,' which is really hypocritical. Idolizing thinness is so incredibly harmful."
—Anonymous, Virginia
9."Mental health professional here. A lot of people don't seem to realize that overachievement is bad for your mental health. Achievement and being good at things are supposed to boost your self-confidence, but constant competition to be the best is not good for your mental or physical well-being. It just runs you down and burns you out. There's a reason you hear about high-achieving students having nervous breakdowns. Your body and brain can only sustain that so long. It's better to focus on being your best and balance that with self-care habits like getting enough sleep, eating a healthy diet, and scheduling time for fun."
"Nobody wants to live as a human doing instead of a human being, which means you have to learn to be in the moment without meeting some never-ending internal expectation of achieving more."
—Anonymous, 45, Texas

10."Dentist here! [Sugary drinks, like sodas.] I've put more people in dentures from Mountain Dew than meth or drugs. It's addictive and so bad for your health and your teeth. Avoid that stuff at all costs!!!"
—Dr-tooth-fairy
11."I'm a former nurse and EMT. Ignoring infections until they turn necrotic. You treat that spider bite or infected scratch today; I wash it out with a sterile rinse and put some ointment. You bring it to me after two weeks, and I'm cleaning out a softball-size chunk of dead flesh and packing it with dressing you're gonna have to change every day for months. You bring it to me after a month? You may lose a limb or at least be in PT for quite a while based on how much muscle you lose."
"The things I've seen from small wounds left uncleaned."
—DoggoAlternative
12."I suggest not playing sports that involve getting hit in the head. If you don't plan on your kid doing professional sports, don't risk all the injuries and future pain from bad joints and old injuries. I've treated many ex-professional athletes. Unless they make it big and sock it away, they end up broken and poor."
—samsontexas
13."Ignoring your diabetes. I've seen people having bad leg and foot wounds; going to dialysis three days a week, four hours each time, just to stay alive; going blind and forced to quit their jobs because they can no longer drive; stepping in a fire ant hill but unable to feel the bites due to neuropathy until their legs were completely covered in welts; having blood vessels diseased all over their body due to constant hyperglycemia, causing heart attacks and strokes."
—Nursebirder
"Untreated type 1 diabetes. It's always so hard to see some young person who thinks they're healthy, but their eye exam shows that they'll be blind before they're 25. Also, they will most likely be on dialysis by that time, too."
—madkeepz
14."Take care of your teeth. The number of patients with endocarditis (heart infection) that started in their rotten teeth is excessive."
—Anonymous, 37, Georgia
15."Wounds that don't heal correctly from trauma may turn into skin cancer! If something isn't healing right, go to the dermatologist! And get your skin checks! If you are over 30, you should get a skin check every few years. If something keeps growing back after picking it, go to the dermatologist!"
—Anonymous, 27, Philadelphia
16."Stop eating sugar daily! From cavities to weight gain to exacerbating chronic illnesses like diabetes, sugar really is the enemy."
—sobe551
And finally...
17."'Nothing.' Being stagnant with your body will literally kill you. Move around. Go walk. Bend your knees. Stretch."
—Gunbuckets
"Inactivity. Most people barely move or consider a slow walk exercise. Daily physical activity of doing chores, walking to the store, etc. are the bare minimum amounts of movement. People use lifts to go up one or two flights of stairs, get delivery, or use the drive-thru to avoid doing even that. Let alone purposeful exercise that would make you out of breath and get your heart rate up. The cheapest way to reduce obesity, type 2 diabetes, high blood pressure, heart attacks, cancer, strokes, sleep apnoea, joint disease, mental health disorders, and pretty much most other disorders? A brisk walk/jog of 30 to 60 minutes five times a week."

Tips to take care of your brain for Alzheimer's and Brain Health Awareness Month
June is Alzheimer's and Brain Health Awareness Month and people hoping to spread that awareness said there are things you can do to take charge of your brain health. Brain changes that cause Alzheimer's can begin 20 years or more before symptoms appear. Work to start on Rockdale Road next week Doing things like exercising, eating right, getting good quality sleep, and controlling blood pressure can improve brain health and reduce the risk of cognitive decline. While age and family history are factors, these can naturally help you to reduce your risk. Millcreek man says over $1000 was stolen from EBT account 'It's not just the individual with the diagnosis, but it's the over 480 thousand caregivers here in the state of Pennsylvania that are providing that care. It's the family members that are in that circle of care who need that information and support. We want people to know they're not alone,' said Sara Murphy, vice president of programs and services for the Alzheimer's Association Greater PA Chapter. Early detection of cognitive diseases is crucial. The Alzheimer's Association also has a help line that anyone can call to get support at 1-800-272-3900. Copyright 2025 Nexstar Media, Inc.

ICE officers stuck in Djibouti shipping container with deported migrants
Three officers and eight detainees arrived at the only US military base in Africa unprepared for what awaited them. Defense officials warned them of 'imminent danger of rocket attacks from terrorist groups in Yemen,' but the ICE officers did not pack body armor or other gear to protect themselves. Temperatures soar past 100 degrees during the day. At night, she wrote, a 'smog cloud' forms in the windless sky, filled with rancid smoke from nearby burning pits where residents incinerate trash and human waste. Advertisement The Trump administration has urged the Supreme Court to stay Murphy's April order requiring screenings under the Convention Against Torture, which Congress ratified in 1994 to bar the US government from sending people to countries where they might face torture. In a filing in that case Thursday, officials told the Supreme Court that Murphy's order violates their authority to deport immigrants to third countries if their homelands refuse to take them back, particularly if they are serious offenders who might otherwise be released in the United States. Advertisement Officials said the conditions in Djibouti highlight the dangers of Murphy's order. 'A small number of ICE personnel are currently guarding dangerous criminals around-the-clock in a converted conference room, under threat of rocket attacks and other security and health hazards — disrupting the base's operations, consuming critical resources intended for service members, and harming national security,' Solicitor General D. John Sauer said in the filing. In her declaration, Harper said officers and detainees began to suffer symptoms of a bacterial upper respiratory infection soon after deplaning, including 'coughing, difficulty breathing, fever, and achy joints.' Medication wasn't immediately available. She wrote that the flight nurse has since obtained treatments such as inhalers, Tylenol, eye drops, and nasal spray, but they cannot get tested for the illness to properly treat it. 'It is unknown how long the medical supply will last,' Harper wrote. The officers spend their days guarding eight immigrants convicted of crimes that include murder, attempted murder, sex offenses, and armed robbery, court records show. Harper said Defense Department employees 'have expressed frustration' about staying in close proximity to violent offenders. Harper said ICE has had to deploy more officers available to work in 'deleterious' conditions to give the initial crew a break. Currently 11 officers are assigned to guard the immigrants and two others 'support the medical staff,' she said. They work 12-hour shifts guarding immigrants, taking them to get medication and to use the restroom and the shower in a nearby trailer, one at a time. Officers pat down the detainees, searching them for contraband. Advertisement At night and on breaks, officers sleep on bunk beds in a trailer, with one storage locker apiece. Some wear N95 masks even while they sleep because the air is so polluted it irritates their throats and makes it difficult to breathe. The area is dimly lit, which Harper wrote poses a security risk to the officers. Department of Homeland Security officials seized on the court filings to criticize the judge. 'This Massachusetts District judge is putting the lives of our ICE law enforcement in danger by stranding them in [Djibouti] without proper resources, lack of medical care, and terrorists who hate Americans running rampant,' said DHS spokesperson Tricia McLaughlin on X. 'Our @ICEgov officers were only supposed to transport for removal 8 *convicted criminals* with *final deportation orders* who were so monstrous and barbaric that no other country would take them. This is reprehensible and, quite frankly, pathological.' But a lawyer for the detainees said they are also worried about their health, whether they are shackled and, the circumstances that DHS has created for them. 'We're increasingly concerned about the conditions of the detainees,' said Trina Realmuto, an attorney for the deportees. Murphy had said DHS abruptly launched the deportation flight even though it plainly violated his April 18 preliminary injunction barring them from removing people without due process. Federal law prohibits sending anyone — even criminals — to countries where they might be persecuted or tortured. Advertisement Although McLaughlin said officials couldn't deport them to their home countries, Mexico President Claudia Sheinbaum said at a news conference last month that the US government did not inform her of the Mexican national sent to Djibouti, Jesus Munoz Gutierrez, who was convicted of second-degree murder in Florida 20 years ago, court records show.

Blood test for Alzheimer's could soon be available on the NHS
A new blood test for Alzheimer's disease has been found to accurately detect early symptoms of the illness, according to new research. Experts from the Mayo Clinic in the US examined two proteins in blood plasma – amyloid beta 42/40 and p-tau217 – which are associated with amyloid plaque build-up, a hallmark of Alzheimer's disease, to provide further evidence that blood tests can accurately diagnose dementia. The study, which was carried out on more than 500 people in an outpatient memory clinic, found the blood test was highly accurate, with 95 per cent sensitivity. That means it was 95 per cent accurate in picking up people with memory problems, with very few cases missed. It was also 82 per cent for specificity, meaning it was also highly accurate in ruling out people without dementia. The blood test has already been approved by the Food and Drug Administration regulator in the US. Dr Gregg Day, who led the study in the Alzheimer's and Dementia journal, said the test was as good as more invasive tests currently in use. 'When performed in the outpatient clinical setting, this is similar to the accuracy of cerebrospinal fluid biomarkers of the disease and is much more convenient and cost-effective.' Overall, researchers found that p-tau217 levels were higher in patients with Alzheimer's disease versus those without the disease. Dr Day said the next steps in the research were to evaluate blood-based testing in more diverse patient populations and people with early Alzheimer's who show no cognitive symptoms. Dr Richard Oakley, associate director for research and innovation at the Alzheimer's Society in the UK, said the results 'suggest this test is very accurate' and could be used alongside other tests and observations from a trained health professional. 'While focused on Alzheimer's disease, the test was evaluated in people with other types of dementias too, showing that it may help with differentiate causes of cognitive decline – though more research in diverse groups of individuals and in community-based setting is still needed. 'Currently diagnosis options in the UK are often slow, expensive and can be invasive, meaning thousands miss out on the benefits one can bring. 'It's great to see blood tests like this approved for clinical use in the US – we hope to see the same in the NHS, which is why we're part of the Blood Biomarker Challenge.' The Blood Biomarker Challenge is a multi-million-pound research programme supported by the Alzheimer's Society, Alzheimer's Research UK and the National Institute for Health and Care Research. Its goal is to bring blood tests for dementia diagnosis to the NHS by 2029. Dr Julia Dudley, head of research at Alzheimer's Research UK, said: 'We urgently need to improve how we diagnose dementia and it's great to see international research working towards this goal. 'Blood tests in this study look at p-tau217 and amyloid beta 42/40, and showed the tests offered high accuracy in confirming Alzheimer's disease. 'This study adds to the growing evidence that blood tests can detect the diseases that cause dementia in people with early memory and thinking problems. 'An important point to consider is that people taking part in research don't always reflect the full diversity of those affected by dementia, who might have additional conditions or other characteristics. 'That is why work is needed to understand whether these blood tests work in a real-world setting.'
