Smarten Up! Everyday Habits That Can Negatively Affect Your Brain

By far, our brain is the most complex, mysterious, and debatably important organ of the human body. It allows us to process information, regulates the body, and makes us sentient beings with feelings and depth. Yet, regardless of how important it may be, unfortunately, there are countless things in our world and decisions that we make that can be harmful. So, protect that beautiful brain of yours and educate yourself on these daily habits that aren't doing your brain any good.

Go Easy On The Television, Especially Reality Shows

In the United States, it's safe to say that reality television is one of our favorite past times. Shows like The Bachelor, Keeping Up with the Kardashians, Real Housewives, and more, are mindless, entertaining, and an easy way to kill some time.

Psychiatrist Dr. Marcia compares reality television to junk food for our brain that does little but slowly chips away at it. Although watching too much of anything isn't necessarily beneficial, reality TV has proven to be some of the most detrimental.

Multitasking Accomplishes The Opposite Of What You're Intending

Multitasking may seem like a faster way of getting things done. In reality, it means that you're semi-completing several things at once. Trying to juggle multiple things takes your attention away from the task at hand, resulting in a worse job than if you were to take on one thing at a time.

Furthermore, the University of London found that multitasking can temporarily drop IQ scores by a whole 15%, with another study claiming it can lead to permanent although mild brain damage.

While many enjoy sleeping with their head under the covers or a pillow, it isn't exactly healthy. Putting a pillow over your head can help keep out light and sound, or show that you want to be left alone.

ADVERTISEMENT

But oxygen is vital for brain function, and if you sleep with your head buried in the covers, you won't be getting the 20.95% of it found in the air that we typically breathe. Furthermore, sleeping like this leads to an increased intake of carbon dioxide, which can kill brain cells.

There's a reason breakfast has been deemed "the most important meal of the day," which many people don't take seriously. It's not uncommon for people to skip it in our hustle-and-bustle society, even though it is damaging to your body and brain.

ADVERTISEMENT

According to a Japanese finding that studied 80,000 people over 15 years, participants who regularly skipped breakfast had an increased chance of high blood pressure and stroke. The study further shows that blood pressure drops after eating breakfast, which can reduce brain hemorrhaging.

If you want to have a better short-term memory, one way is to stop chewing gum. Although chewing gum has shown to help reduce stress, which is always good for the brain, it's detrimental to your short-term memory.

In a 2012 study from Cardiff University in Wales, participants that were chewing gum had a harder time recalling a list of words and numbers in the order that they were presented than those that weren't in the act of chewing.

Although sleep is necessary for all bodily functions, today, people are getting less sleep than at any other time in human history. Back in 1900, people slept more than 9 hours a night, and by 1975, it had decreased to 7.5 hours and is still increasingly falling.

ADVERTISEMENT

According to the CDC, over one-third of the 440,000 people surveyed reported that they were getting less than 7 hours of sleep a night. A lack of sleep can reduce cognitive function and even kill brain cells. Now, get to bed!

Although anyone trying to lose weight knows to stay away from an excess of carbs, eating too much, in general, is detrimental to your cognitive abilities. In a 2012 study, it showed that overeating could increase the chances of developing memory loss or mild cognitive impairment in the later years of life.

In today's work-driven society, people are more willing than ever to work while they're sick instead of using one of their precious sick days. Not only does it put everyone else at risk that you work with, but it's terrible for your own wellbeing.

ADVERTISEMENT

Your brain is using extra energy to try and fight your illness and get your body healthy, so trying to work at the same time puts it into overdrive. So, working while your sick might not only further weaken your immune system but slows cognition.

Socializing Is Important

While some people may pride themselves on being introverts and their lack of need to be around other people, that's not necessarily healthy. If you're constantly alone and not interacting with other people, the parts of your brain that control language, memory, and organizing thoughts can begin to suffer and weaken.

Although being alone has its benefits, it's important to engage in conversation, which acts as a much-needed exercise for your brain. And no, that doesn't mean just texting someone.

Fats are an important part of a healthy diet, but too much of them, especially those that are saturated need to be minimized. As it turns out, a Vanderbilt University study discovered that people who eat too many fatty foods can develop a brain defect that affects their ability to realize that they are full.

The American Heart Association may recommend eating a type of fatty fish once or twice a week to benefit your heart, but eating too much of it isn't necessarily good for your body or brain.

ADVERTISEMENT

Fish such as bigeye, ahi, albacore, and yellowfin tuna are all high in mercury, which is toxic and can cause cognitive disruption. If you're a fish lover or have a dietary restriction, change it up a bit and add some anchovies, trout, or salmon to your meals instead.

Even though a large part of the population is required to sit for the majority of the day, whether it be in a classroom or at work, we're not designed to do this. Not only does it increase weight gain due to immobility, but there can be even worse side effects.

ADVERTISEMENT

An article by The Washington Post reads, "Moving muscles pump fresh blood and oxygen through the brain and trigger the release of all sorts of brain and mood-enhancing chemicals. When we are sedentary for a long time, everything slows, including brain function." To combat this, be sure to get up and move every hour.

While many people don't have the ability to choose exactly where they want to live, every place has a different impact on your brain-- some places better than others. For example, if you live in a bustling city, you're more likely to breathe polluted air, which decreases the amount of oxygen that goes to your brain.
