40. Babies Are Getting Bigger<\/h2>\n
Natural selection determined that smaller babies are the most likely to be born alive. Why? Because smaller babies are easier to fit through the pelvis without harm to the mother or child. The result is a healthy baby and a healthy mother. In older times, a large baby’s birth could potentially kill the mother by getting stuck in the birth canal, leading to exhaustion and death, or causing a traumatic delivery. Tearing during blood loss could easily lead to post-birth infection and sepsis, once known as childbed fever, which killed many historical women, including at least one of Henry VIII’s wives.<\/p>\n With the rise in C-sections<\/a>, however, larger babies are much more likely to survive. You probably know somebody who either was or has had a child upwards of nine or ten pounds. Even just fifty years ago, that child probably would not have survived birth. Low birth weight is now often considered a sign of ill health and an increased risk of complications, including sudden infant death syndrome (SIDS.) While once valued, low birth weight is now associated with prenatal tobacco and alcohol use and pre-term deliveries. Interestingly, high birth weight is related to potential health impacts, including diabetes in adulthood.<\/p>\n <\/p>\n Women’s pelvises are getting narrower<\/a> for the same reason that babies are getting bigger: the rise in C-sections. Women with narrow pelvises have historically been much more likely to die in childbirth, while women with wider pelvises had the necessary adaptation to survive. The hourglass figure that is typically depicted as the standard of beauty emphasizes wide hips. These were once desirable features that subconsciously suggested a woman would likely bear healthy children. Thin, waiflike women being viewed as beautiful is a relatively modern conception, accordingly. In older times, such women wouldn’t have been nearly as desirable as potential wives.<\/p>\n Why didn’t all women with narrow pelvises die in childbirth so that only the genes for wider pelvises survived? See point number one. Babies used to be much smaller, so a woman with a narrow pelvis could have given birth to a five- or six-pound baby and lived. Also, the genes involved in selecting pelvis width may include other beneficial factors, allowing the genes for narrower pelvises to be chosen regardless. Whether it be eye color or pelvis width, the inheritance of any single trait is an incredibly complex process that often involves multiple genes and factors.<\/p>\n <\/p>\n When is the last time you had to memorize a phone number or email address? Was it before you started using Google? Before search engines, we routinely had to learn information or write it down. Many of us had to learn to memorize our home phone numbers, emergency contacts, and addresses in elementary school, which was a common safety issue at the time. Parents carried physical photos of their children in their wallets in case they became lost. These functions are now easily replaced by saved cloud data and a smartphone, which even many young children now possess.<\/p>\n Now, we are so reliant on search engines<\/a> that we are losing our ability to recall information. We are more likely to forget information if we can look it up on a search engine later. While the physical processes of creating and retaining memories may not have permanently changed, the way we interact with the need for memory is so drastically different from the measurable changes. The need for long-term storage, especially of complex sequences of numbers, such as phone numbers, simply isn’t a necessary skill for most people in our current technology era.<\/p>\n <\/p>\n Consider the foods that our hunter-gatherer ancestors ate upwards of 10,000 years ago. They ate meat – which may have been uncooked – and tough, fibrous plants. To cope with the pressure of chewing those foods, their jaws were more massive, and they had bigger face muscles. While large jaw examples like the Hapsburg jaw are incredibly dramatic to our modern eyes, our distant human relatives probably also looked quite heavy in the jaw. While it is almost unthinkable now, eating once took an inordinate amount of effort, not only in finding food but in the strength required to consume it.<\/p>\n Today, most of our food is quite soft, except for potato chips and the occasional raw vegetable sticks. As a result, our jaws are smaller<\/a>, and our face muscles are not nearly as well-developed. When is the last time you can remember having to work to chew up food? Our steaks are tender, most of our snack foods melt in your mouth, and nuts and raw vegetables are surprisingly expensive and therefore difficult for many to eat regularly. It is worth questioning if our current diet of soft foods allows for easier overconsumption than foods that would eventually tire the jaw.<\/p>\n <\/p>\n Our hunter-gatherer ancestors had strong bone structures because of their strenuous lifestyles. They had to stalk and kill prey, a feat that can tax even the fittest individual. That lifestyle made their bodies stronger and sleeker than ours. Their animal product dominated diets also contained a different variety of nutrients than our modern diets, whether vegetarian or junk food. While we fortify some products, like cereals, vitamins like Vitamin D, an essential element of bone health, are notoriously lacking in many modern western diets. There is also no question that life was harder on their bodies, making a strong frame necessary.<\/p>\n Today, we are much more sedentary than our ancestors. We might go to the gym for an hour a few times a week, but that effort is nothing compared to what was required of our hunter-gatherer ancestors to survive. As a result, our bones are less dense and more prone to breakage<\/a>, especially as we age. Our diets also have gaps and weaknesses that older diets wouldn’t have, especially animal products. While hunter-gatherers likely lacked some vitamins, they had diets rich in protein, iron, and calcium to support healthy bones’ formation and maintenance.<\/p>\n <\/p>\n Some people think that all modern technology is of the devil, but the horn that you may be growing from your smartphone is not a devil horn. It’s called an external occipital protuberance, and it is at the base of your skull, where it meets your neck. You may be able to feel if you have one, and if you or someone you know is bald, you may be able to see theirs. While it may sound funny to imagine growing a horn, any skeletal deformation caused by posture or lifestyle issues can cause pain and other health complications.<\/p>\n The external occipital protuberance forms among people who spend a lot of time looking down. Previously, it was mostly seen in scholars who spent a lot of time with their heads in books. However, with so many people having their heads in their smartphones<\/a>, those protuberances are much more common. The next time you find yourself routinely hunched over your smartphone, think of your bones and make sure you take frequent breaks to look up and stretch out. Future archaeologists may very well wonder what we all were doing if they find nothing but horned skeletons from our era!<\/p>\n <\/p>\n Today, our skulls are as much as 10% smaller than those of our ancestors<\/a>. Why? Because our heads’ shape is determined not only by genetics but also by the foods we eat. Like those that our hunter-gatherer forebears lived on, nutrient-rich foods caused their bones and muscles to become much stronger than ours. Their skulls were larger and stronger, and their jaws were larger, a necessary skeletal feature due to the strength required to safely chew the tough means and fibrous plants they lived on. As our diets have gotten more processed, our skulls have shrunk.<\/p>\n Additionally, the effort required in chewing food helps determine the shape and size of your skull. Chewing natural foods requires more energy, so before modern times, people had larger heads to masticate. Nowadays, we eat so much processed food – which tends to be quite soft, as well as nutrient-deficient – that our skulls are not growing as big as they once did. While all of the easy access to nutrients makes humans taller than ever, it has the opposite effect on our heads. If more natural foods keep making a resurgence, perhaps our heads will grow larger again.<\/p>\n <\/p>\n The reason why children’s faces are changing is the same reason why our skulls are shrinking. It is because of the foods that so many children are eating. Before modern times, most children are nursed for the first two years of life, and that process affected how their faces and mouths develop. Using bottles and sippy cups requires different muscles, causing the skull to grow differently and affecting the face. With the current trend of nursing children for a longer period, it will be interesting to see if children’s facial structures continue to change or start reverting to older forms.<\/p>\n Additionally, children are consuming processed food earlier and earlier in life. Instead of learning to chew on natural foods<\/a>, which can help their skulls take on the proper shape while still soft and malleable, they eat soft, processed foods. Most “healthy foods” marketed to toddlers are heavily processed and affect as much as candy. Most children’s foods are highly processed, and even disregarding the sugar content, the soft texture alone is causing measurable changes. From soft crackers to processed meats, children encounter very few foods that require vigorous chewing that fully uses the jaw muscles.<\/p>\n <\/p>\n A hundred years ago, most teenagers were either working on farms or learning a trade. The idea of the “teenager” as a social category didn’t even emerge until the Baby Boomer generation. Nowadays, teenagers spend so much of their lives on social media that they are developing quite differently. Teens often go directly from school to extracurricular activities to a job, with little time for relaxation outside of screen time. That screen time is most often spent on social media, as it allows for connection to one’s equally busy peers. Unfortunately, popular forms of social media are often rife with bullying<\/a>.<\/p>\n Furthermore, one effect of that development is particularly pronounced: rises in anxiety, depression, and other mental disorders. These problems can be seen across any age spectrum, but they are particularly troublesome in teenagers, as they are trying to find and create their own identities and find their way in the world. Between bullying, the pressure to conform to social or beauty standards that may not be possible, and the curated effect of only seeing everyone else’s positive moments, social media is a recipe for mental health hardships for young people. The pressure social media puts on today’s youth is staggering.<\/p>\n <\/p>\n Have you heard of FOMO? It stands for Fear Of Missing Out<\/a>. If you are a heavy social media user – if getting dozens or even hundreds (if not thousands) of “likes” on your posts and photos gives you a buzz that you need to get through your day – then you may have it. The curated nature of social media, in which you only see positive moments like vacations from everyone around you, can lead to the idea that you aren’t living your life to the fullest, which drives the fear of missing out on some intangible joy of living.<\/p>\n FOMO causes people to check their social media handles much more than they ordinarily would. And it’s not just a term to describe why people check their social media. It’s reflective of how social media is rewiring our brains. For many, seeing the approval of their peers, or even strangers, through likes, comments, etc., can release dopamine, one of the brain’s reward chemicals. That causes a reinforced feedback loop in which people continue to check their social media more and more for that feeling of validation. The way we use social media can change our brain chemistry, leading to new disorders.<\/p>\n <\/p>\n Our brains are pretty impressive at regulating the time even when we aren’t consciously aware of what time it is. Think about the circadian rhythm – you can fall asleep and wake up at about the same time regularly without even thinking about it. Many people can generally sense when a rough unit of time has passed, whether it be a minute or an hour. That is all linked to our attention span and how it perceive the passage of time. As we become more reliant on devices<\/a>, the sense of time and, with it, attention span is becoming weaker.<\/p>\n Moreover, if you are getting used to checking your smartphone every three minutes, your brain will automatically set up a “timer” to make sure that you check it every three minutes. As a result, your ability to focus on tasks is severely hampered. In other words, if you check your smartphone frequently, you probably have developed the attention span of a three-year-old. The dopamine received from seeing positive feedback when checking your social media can shift the balance of chemicals in your brain, reinforcing repetitive behavior. In addition to mood changes, social media devices are rewiring our brains.<\/p>\n <\/p>\n Historically, we evolved as group beings because those who have a group of people around them are much more likely to survive. When calamity strikes, those who come out stronger are those who have secure networks of people that step up and help each other. But we are losing this ability, and modern technology is to blame. Social media allows us to have large, loosely connected networks of people in geographically diverse locations that cannot easily be assembled or even reached in emergencies. We rarely physically interact with these people<\/a>, relying solely on digital communication methods.<\/p>\n People who are addicted to their smartphones lose the use of parts of their brains responsible for focus. As a result, they are less able to engage in uninterrupted time with other people. Nevertheless, it isn’t limited to those who are addicted to their smartphones. We live so much of our lives on social media that we have begun to lose the ability to interact with people face-to-face. Should a large-scale disaster strike, we may not be able to cope with it, and we may have lost the social skills required to build a network in the event of a disaster.<\/p>\n <\/p>\n The term “popcorn brain” goes back to 2011, when Dr. David Levy<\/a>, who works out of the University of Washington School of Information, wanted to describe some of the effects that smartphones were having on people’s brains. In short, their cognitive abilities were diminishing. As already discussed regarding attention span, social media, and smartphone devices rewire people’s brains and shift their brain’s chemical balances. The dopamine hits from social media help to create repetitive behaviors of checking phones and apps. The validation found from those sources and the ease of finding it makes it hard to focus on other activities.<\/p>\n The term “popcorn brain” refers to the idea that people who are always online cannot focus and that their brains continuously shift from one idea to the next. It’s like they are constantly scrolling through a news feed, even when they are not online. While the ability to rapidly shift tasks can be incredibly beneficial in some high-pressure careers, it is often detrimental and frowned upon in most walks of life, as anyone with ADHD can attest to. Most work requires us to focus on single tasks for extended periods, something that the popcorn brain makes increasingly tricky.<\/p>\n <\/p>\n We are so used to regularly checking our email and social media handles that we are continually seeking out new information. However, we aren’t necessarily trying to explore our world to gain that information, something that our ancestors did as a means of survival. Any curious element of the world was immediately a source of fascination in past eras, as human survival and society’s expanse were dependent on constantly finding new information. All of the scientific and artistic revolutions were centered on the insatiable desire for exploration and understanding, significantly reduced by having knowledge at your fingertips.<\/p>\n Instead, we are trying to strike the part of our brains known colloquially as the “pleasure center.” That is the part of the brain that lights up when we get a new email or buy something new. We are always trying to light it up, but at the same time, we are losing the ability to gain information about our environments. Social media is especially effective at lighting up the “pleasure center,”<\/a> releasing dopamine in the process that acts as the brain’s reward chemical. This process makes it far more rewarding to check social media or window shop than read new information or research a topic.<\/p>\n <\/p>\n Isaac Newton had his “Eureka” moment while sitting out in an apple orchard when an apple fell on his head. When was the last time you just sat outside underneath a tree, not thinking about anything in particular? Do you remember the feeling of having a clear mind and brilliant ideas coming to you? When was the last time an idea out of the blue struck you? When did you use your imagination? With the constant bombardment of stimulation and information from smartphones and social media, we simply aren’t reliant on our imaginations anymore.<\/p>\n Kids today are unable to have this experience because of how technology is messing with their brains. In fact, studies show that students who spend 10 hours a day online actually have lower IQs than students who spend two hours a day or less online. No matter how young, the brain tends to seek pleasure and reinforcement rather than new information or learning, so easy access to social media may mean reduced cognitive ability<\/a>. It is undoubtedly reducing the use of imagination, as any question or idea can instantly be answered or conjured up by the internet.<\/p>\n <\/p>\n Anhedonia<\/a> refers to a reduced ability, or even inability, to experience pleasure. It is because of the same reason why people who begin using drugs need higher and higher doses to get the same effect. Tolerance is the brain’s ability to become used to new input and stimuli, whether drugs or new hobbies. The initial rush of joy you get will likely diminish over time as the chemicals produced by your brain adjust and level out regarding the new experience. Much as with drugs, overdoing a pleasure-providing behavior can also cause tolerance and reduce the ability to feel much at all.<\/p>\n Spending much of our free time online – whether we are doing online shopping (mostly as retail therapy), checking email, or updating our social media to get new “likes,” comments, and shares – is hijacking our brains in the same way that drug addiction hijacks an addict’s brain. We need higher and higher doses of stimulation to get the same feeling of pleasure. The dopamine provided by a similar level of positive online feedback will naturally adjust and lower over time, necessitating more and more shopping, posting, commenting, scrolling, etc., to get the same level of excitement, fulfillment, and joy.<\/p>\n <\/p>\n Myopia<\/a>, the scientific term for near-sightedness, used to be something rarely seen outside of those who are in their fifth decade of life or higher. Being able to see clearly was a necessary survival skill until very recently. Imagine pioneers roaming the prairies when they cannot see a wild herd of buffalo in the distance! Now that children are spending so much time in front of screens, especially while their eyes are still developing, they develop myopia earlier and earlier in life. Most of the light they see is artificial rather than natural light, gained from spending time outdoors.<\/p>\n More kids need prescription lenses, even when they are not genetically predisposed to vision problems. In fact, in Seoul, South Korea, 96% of 19-year-old males have myopia. In China two decades ago, only about 10% of children were myopic. Now, that number is closer to 90%. The ability to easily treat near-sightedness enhances this issue, as near-sightedness in earlier eras would have been disastrous and dangerous, making it far less likely the genes would be passed on. Today, no one would ever consider someone at risk or unfit in life due to having to wear glasses as they are nearly ubiquitous.<\/p>\n <\/p>\n Just a few decades ago, type two diabetes was limited to those who are elderly. Type one diabetes, also known as juvenile diabetes, was the only time doctors would see in children. However, with the high amount of processed foods – especially those high in sugar, that children are eating – coupled with the amount of time they are spending online rather than outside playing, children younger than eight years old are being diagnosed with type two diabetes<\/a>. We have yet to see how this health crisis will affect the genome, especially since Diabetes does appear to run in families.<\/p>\n Given the expense of treating diabetes and the horrible complications it can lead to, including blindness and loss of limbs, the idea of generations facing a high rate of Type 2 Diabetes is genuinely worrisome. The medical community will have to grapple with providing a huge amount of intensive healthcare to future generations if high diabetes rates continue. It could lead to a reduction in life expectancy and the overall quality of life for those affected. Understanding the increase in Type 2 Diabetes is doubtless a top priority for medical researchers to avert the coming crisis.<\/p>\n <\/p>\n Back in the 1980s and 1990s, not getting enough sleep meant that you were tough. If you were tired when you went into the office, you could wear your exhaustion as a badge of honor, especially if you could still manage to power through your workday. Getting a bad night’s sleep was remarkable enough to be a topic of discussion and would garner commiseration and pity from your coworkers and friends. Insomnia was still a somewhat uncommon medical condition that would command your doctor’s attention. Bedrooms were set up in a way conducive to sleeping, with minimal light pollution or notification sounds.<\/p>\n Now, we are so busy, and our lives are so consumed by technology<\/a>, that being sleep-deprived is a normal state for most people. The number of people getting a full seven to eight hours of sleep a night regularly is relatively low. As a result, we are increasingly distracted, less focused, and less aware of what is going on. Long-term sleep deprivation can create many adverse health effects, including weight gain, lowered mood, loss of ability to focus, and more. Most Americans are now at risk of these health effects. Why? Because of the average of 5-6 hours of sleep that many are getting.<\/p>\n <\/p>\n If you take your smartphone to bed, there is a good chance that you are one of the many adults that are struggling with insomnia<\/a>. You may go to bed exhausted, but if your smartphone is on your nightstand or right beside your pillow, you may struggle to fall asleep. The reason is that your brain needs to calm down for you to fall asleep. However, if you keep checking your smartphone every few minutes, you will miss the state of relaxation necessary for deep sleep. You will develop insomnia and become increasingly distracted, irritable, and tired.<\/p>\n The light and sound pollution from the blinking notification lights and alarms also contributes to insomnia and is the same reason televisions are not recommended in the bedroom. The amount of stimulation that phones provide is not remotely conducive to a calm, full night’s sleep. Add to that the constant, chemically reinforced temptation to check your phone for social media notifications, news alerts, or even just to check the time, and you have a recipe for a night of tossing and turning. The distractions created by a smartphone next to your bed or under your pillow could also prevent valuable deep sleep.<\/p>\n <\/p>\n Our smartphones don’t just make us increasingly distracted and, well, dumber. Smartphones and other gadgets with screens emit blue light, which the brain mistakes for daylight. If you check your smartphone or use your computer in the evening, you trick your brain into thinking that it is still daylight and that it needs to stay awake and alert. As a result, your brain doesn’t secrete as much melatonin as it should. After all, it is trying to stay awake, not fall asleep. With decreased melatonin<\/a>, you aren’t just sleeping less. You are disrupting your entire hormonal chemistry and body’s metabolism.<\/p>\n This effect has led to a proliferation of gadgets to block blue light, like yellow polarized glasses lenses, to help people restore healthy circadian rhythms. Many smartphones and other devices now also include helpful nighttime modes. These reduce or eliminate blue light, allowing the body to ease into a natural state of sleepiness. If you currently struggle with not feeling tired at bedtime, checking your devices for a nighttime mode could be an easy way to make a healthy change. While circadian rhythms and sleeping norms have changed throughout the ages, experts agree that our current cycle is not working.<\/p>\n <\/p>\n Codependency is a severe problem<\/a>. It’s more than relying on other people in difficult times – it’s losing your personality because you rely on someone else to solve all of your problems. Imagine a hunter-gatherer not getting up to go forage because he is waiting for someone else to tell him what to do. That’s what’s happening to people today, thanks to cell phones and social media. They’re refusing to live their lives on their own terms because they are waiting for other people to permit them. People are codependent on social media and will not do anything that they cannot post in exchange for “likes.”<\/p>\n However, on a less extreme level, consider how many times a day, teenagers call their parents to update them on every little thing. Two decades ago, we would find it problematic if anyone called their parents that often. But now, it’s the norm and has even caused the rise of a new form of parenting called “helicopter parenting.” As a result, they have codependent relationships with their parents. However, they are unable to separate from them. The ability to be in constant contact with other people dramatically increases the risk of forming unhealthy codependent relationships. This notion is for friendships, romantic relationships, and more.<\/p>\n <\/p>\n Being quiet and alone is a necessary skill<\/a> that humans developed long ago. Imagine your hunter-gatherer ancestors waiting quietly for hours at a time while stalking out prey. Imagine doing that now, without any smartphones or distractions, just waiting quietly. In addition to hunting games, being quiet and alone improves the brain’s chemistry so that it enhances intimacy and human connection. We are missing out on those things thanks to the constant presence of social media and online personas. Absence indeed makes the heart grow fonder, and the brain’s chemistry to boot.<\/p>\n With so many distractions around us nowadays, we have largely lost the ability that allowed our ancestors to survive for tens of thousands of years. In particular, kids don’t have any alone time, which could be short-circuiting their intellectual and social development. When people aren’t connected, they feel lonely. In older times, children sat alone to read, play quietly, draw, or engage in other activities that require imagination. While children today have more access to their peers thanks to social media, it may be at the cost of forgetting how to be comfortable with being alone.<\/p>\n <\/p>\n Getting enough rest has long been critical to the survival of humanity. Nowadays, we aren’t just not getting enough sleep. We are experiencing higher levels of fatigue. Why? Not only because of less sleep but also because we spend more time in front of screens instead of outside. The combination of disturbed sleep thanks to all of our various smart devices<\/a> and the disruption of our circadian rhythm from blue light exposure creates a disastrous wave of insomnia and fatigue for the vast majority of adults and many children. Such reduced sleep has many associated and long-term health risks.<\/p>\n When we spend time in front of screens, our brains feel drained and unable to cope with life tasks. However, when we spend time outside with people, we feel satisfied with life and rest without the distractions of smartphones. Since we have exchanged time outside for screen time, we are increasingly fatigued. Physical insomnia, once a reasonably unusual medication condition, is also plaguing most people. Whether it be from stress, constant blue light exposure, or the temptation to keep checking their phone for a dopamine hit, people are fatigued at unprecedented levels, despite physical labor being less performed than at any time in history.<\/p>\n <\/p>\n Being able to hear things in the distance has long been a necessary skill for survival. Now, however, many people are developing hearing loss and the reason why isn’t old age. While we expect seniors to grow age-related hearing loss, it’s happening in younger and younger people. The reason why is how many people continuously have headphones in<\/a>. They aren’t just unaccustomed to silence; they are continually blaring music into their ears and damaging their hearing. Kids at increasingly younger ages are experiencing hearing loss because of their headphones and using them dangerously.<\/p>\n The types of sounds people are now exposed to are also vastly different than in past eras, where the sound of a jackhammer or jet engine would have been monstrous and unimaginable. Today you can easily listen to bass lower than people would have ever heart in nature, as well as treble that pierces more than a baby’s cry. While we have a wealth and diversity of sound today, many of them can permanently damage our hearing if misused. Unfortunately, few devices made today come with safety measures that keep you from listening to dangerous levels of sounds.<\/p>\n <\/p>\n A generation ago, you probably had sore muscles from a hard workout, like an intense PE period at school. However, now, the amount of time we spend on technology is forcing our bodies into awkward positions for so long that we have more aches and pains. Posture and repetitive motion injuries, often associated with desk work, are prevalent sources of expensive workplace injuries. Carpal tunnel, which usually requires surgical treatment, is incredibly common now from bad computer station ergonomics. Back and neck problems are also expected from improper posture over the long eight or more hour workday.<\/p>\n![\"Crawling](\"https:\/\/dev.sciencesensei.com\/wp-content\/uploads\/2019\/08\/shutterstock_189429203-1.jpg\")
