Scientists, What's More Dangerous Than People Think? - AskReddit

most people don't really know that it is used on everything new that you buy scientists what is something that we use or do that hasn't been yet proven to be harmful but you suspect that it is nanoparticles specifically those composed of heavy metals they are so small that we haven't been able to get a clear picture of the effects that they might have but you find them everywhere sunscreen moisturizer car emissions research is beginning to show that they could be potentially harmful to lung and cardiac tissue they are so small that your body's natural defense can't block their entry key point here is that we don't know they could be very harmful but they might be fine luckily we've developed the instruments and experimental models that will answer this question go science home air fresheners the plug-in kind every sit near one too long you're going to have a headache regardless of the scent of your sensitivity deodorant many of the best sellers have known carcinogenic ingredients we are wearing it daily directly on top of lymph nodes and our children are now wearing it due to puberty starting at younger and younger ages certain food dies many food ingredients and dyes are illegal and banned in other parts of the world but considered safe and fda approved here in the states the extreme use of workout supplements by teenagers college kids and athletes none of it has been proven none of it has significant research to back it up and the duda gnc has absolutely no idea what it does while it isn't an adverse effect the first or second time we see that there are radical effects over several years of using them for example an increased level of exogenous creatine will result in an excess exogenous quantity of blood creatinine your kidneys will have to pull this creatinine out of your blood and at high levels creatinine will cause high stress on said kidneys over time they will become overworked and under efficient showing damage and signs of the first stages of kidney disease scented candles yeah scented candles are meant to smell nice but in reality you're contributing to your indoor pollution something that is a serious issue in low ventilated homes you're combusting random chemicals and releasing them into the air i wouldn't be surprised if a report comes out on their carcinogenic properties i believe that preventing kids from picking their nose and eating their boogers may increase the chance of developing seasonal allergies this is basically an extension of hygiene hypothesis some of the early research regarding this suggests that exposing our immune system to antigens through our gi tract at an early age will train our immune system to not react to them this is supported by research showing individuals in israel having the lowest incidence of peanut allergies likely due to the common practice of feeding their babies a peanut-containing snack other new research confirming and suggesting early exposure of children to things like eggs can reduce the incidence of allergies if the mechanism for this is in fact exposure of antigens through the gi tract at an early stage and boogers contain the antigens of a lot of the substances that cause seasonal allergies at least locally then eating boogers as a kit should prevent seasonal allergies assuming you live in the same place you grew up in medication the development of pharmaceutical drugs and technological advancements in medicine is extending the lifespan of individuals with genetically linked diseases well past the age of reproduction this means that those displaying symptoms that are traditionally detrimental to survival are able to pass these traits onto their offspring instead of allowing natural selection to rid of them from an evolutionary point of view deleterious alleles are remaining in the population and humans are not progressing genetically of course this view is a very darwinian definition of evolution mutations will inevitably occur in any population these are actually beneficial to the diversity of a gene pool furthermore the human kind is arguably evolving from a different perspective technologically culturally etc i know i'm deviating from the question but just an interesting thought the long-term consequences of widespread vitamin d deficiency especially in children due to rampant use of sunscreen and a general shift towards indoor life 75 of us teens and adults are vitamin d deficient and the health implications could be widespread i've long wondered if there's a connection to the explosion in food-related allergies that has occurred concurrently food allergies and anaphylaxis seem to occur at higher latitudes for example places with less sunlight at greater frequencies it wouldn't surprise me at all if vitamin d deficiency is eventually linked to occurrence of food allergies seven day weeks only humans break up time this way and i often feel we would be happier if we had five day cycles where we worked for then had a day off or some other variation but the system is so attached to how our society operates that it seems unlikely to ever change despite how the way we live has changed if anything we've started working more and people are needing even more distraction to try and calm their stress women that are able to breastfeed their baby but still choose to give formula instead i understand that for different reasons some babies cannot have breast milk for example lactose intolerance but out of laziness it's going to help new moms get back to their pre-pregnancy weight it burns up to 400 kilocalories per day provides more complete nutrition than formula since they still can't perfectly replicate breast milk it boosts the baby's immune system from chemicals from the mother and the milk formula is expensive studies have shown that children who were breastfed had significantly lower rates of obesity later in life some studies showed figures of up to a 30 reduction in chance of becoming obese the list goes on it is slightly inconvenient to the mother for a time sure but the benefits far outweigh the inconvenience the correlation between hormonal bc and the rising divorce rate while largely untested there are suspicions within the neuroendocrinological community that using hormonal birth control can affect how attractive a woman perceives a man based on how bc can alter sensing chemical cues remember that video where women rated how pleasant a man's dirty gym socks smelled and the ones they rated highest correlated to the men with the most dissimilar immune system sort of like that there are many aspects to attraction that transcend normal relationship pillars like matching personalities a large part of feeling emotionally connected to someone else is based on how viable your offspring would be based on your genetic differences the body can literally smell this so when women are dating and don't want to have kids they're on bc when they get off of it and want to have kids their entire hormonal makeup changes this could lead to choppy water when suddenly the attraction a woman feels for a man disappears without bc everyone knows formaldehyde is bad for you right nasty side effects and such most people don't really know that it is used on everything new carpet probably has traces of formaldehyde new leather furniture formaldehyde pressure treated wood formaldehyde even new curtains formaldehyde it is one of the most common chemicals used in manufacturing here is the bonus to fix it if you suspect it in anything new that you bought crank the heat in the room open a couple windows and leave it like that for the weekend the trace is off gas then you are good deodorant a lecturer of mine has devoted her life to prove that the chemicals in deodorants cause breast cancer she's found that a disproportionate amount of cancer start close to the underarm when reason would suggest they would start all over of course there may be an entirely different reason for this we just don't know yet her evangelicalism can be overpowering sometimes but i think she may be onto something washing up liquid adverts for it always show the dishes looking lovely and shiny but covered in bubbles for dramatic effect hardly anyone i know washes and then rinses their dishes they fill the sink or a bowl in the sink with soapy water and wash the dishes in there taking the soapy dishes out and standing them to dry or drying them without a thorough rinse there has been an increase in esophageal cancer in the uk since the 70s of course i can't say they are related but come on people why not rinse don't bathe in rosemary oil i was at a hazardous chemicals conference for work about half a year ago and sat down for drinks with some people i'm at one of them was a guy who worked at a testing lab and we asked him what substances were horribly dangerous that we wouldn't even know about his response rosemary oil basically any company that started doing any research on the toxicological effects of herbal oils ended up shutting down the company to keep the results from going public right now there's a huge uproar in the community over phthalates because they caused a 10 reduction in reproductive capacity in rats 10 percent could be a bad night of drinking in comparison rosemary oil made their balls fall off his phrasing he went on to say that it makes sense if you think of it you have a million years of evolution as a plant and if things are eating you there are a few defenses you can develop you could be acutely toxic and kill the salad eaters you could taste bad and deter them or you could be reproductively toxic and keep them from having kids thing is that as humans we eat such a small quantity of these herbs that it doesn't do much to hurt us but it's still really interesting i came across a case report of a patient tearing a tendon in their forearm from excessive texting and using their phone thirty-some years for now i'd wager that there will an increased prevalence of chronic phone use injuries i imagine deafness will be up there too the amount of loud music people listen to these days is ridiculous when i was 16 i went to a loud concert that gave me ringing for a month it never really went away but i forget about it now since then i am super protective of my ears and can't fathom why people go to clubs it's so goddamn loud i'm glad i still have enough hearing to realize how ridiculously over the top it is i think social media will absolutely devastate the political system as we know it it's the 24-hour news cycle on steroids misinformation or even blatant lies can literally reach millions in seconds people can take one sentence out of an hour-long speech and blow it miles out of proportion more value is being placed on grandstanding our leaders spew out slews of words that mean nothing at least in the past the nightly news reporter had to mull over whether something was important enough to waste valuable air time over when we got 24-hour news that gatekeeper ended but at least a reporter and a news team had to decide what was newsworthy now any idiot who can barely rub two rocks together can get on twitter and make big media frenzies over petty crap looking at you social justice warriors people then make it worse as they trim their facebook and twitter feeds to only echo back what they already believe we've created an entire society that rarely has anyone challenge their beliefs an average member of the general population vastly overestimates how many other people share their beliefs our political information is all based on the news equivalent of junk food and we are isolating ourselves to only eat one specific flavor of it critical thinking is dying out a republic can't really work without a thoughtful population vaping who knows what's in those oils no regulation of it and the cult around it seems to have absolutely no skepticism about it whatsoever talk to some of the people who are passionate about this and say don't you wonder if this is unhealthy and they will jump down your throat with all the reasons it's not only not unhealthy but this stuff is practically good for you the articles last week which linked to studies that called it safer than smoking were lead into reddit with headlines like vaping is safe it's completely insane i get that these things are helping people quit smoking and that's great just maybe apply a little caution about the stuff you ingest from time to time [Music] most of the plastics we wrap our food and contain our beverages and are probably harmful for us if released into the food through heat or light i'm a polymer chemist and use only glass tupperware never heat anything in plastic and avoid plastic bottled drinks as much as possible for example human breast milk contamination with phthalates and alterations of endogenous reproductive hormones in infants three months of age and that's just from the phthalates passing through the body and into the breast milk study on the leeching of phthalates from polyethylene tear of phthalate bottles into mineral water phthalates are definitely coming out of the breast milk storage bags to be honest i'm really surprised how low plastics in general is considered as harmful untested supplements walk into any gnc or whole foods and see hundreds of bottles of natural supplements claiming to cure just about any ailment conveniently most haven't been tested in placebo-controlled trials for the condition they claim to help treat so my thought as a phd molecular biologist is how much herbal placebo does one have to take into those comically sized pills before it starts having a negative effect whether on your own physiology or your gut flora about 32 percent of babies in the u.s are delivered by cesarean section there has been evidence that babies being exposed to good bacteria from their mothers via normal delivery can have protective factors obviously there are situations where c-sections are necessary but overuse may be contributing to higher rates of allergies in children among other issues sitting at a desk looking at computer screens all day i know that we are meant to take breaks and whatnot now but my eyes definitely feel worse during long stints of data analysis convenience technology gadgets are coming out left right and center trying to make our lives easier and in turn making us lazier both physically and mentally for adults this isn't such a big deal but for children going through brain development this could be an issue artificial sweeteners especially with long-term use it's already been found that artificial sweeteners negatively affect the microbial communities within your body and it was previously found that some sweeteners would make poisonous by-products in your body i can understand the desire to switch to something sugar-free but maybe considering toning down on sugar intake instead of finding potentially poisonous alternatives would be the better alternative thanks for listening to radio tts hit the subscribe button and activate the notification bell for more
