11 habits that damage your brain Isn’t it interesting that the organ in our body in
charge of thinking is often the one we think about the least? Everyone worries about their health,
their looks, etc. But, people seldom think about the state of their brains. Nevertheless, the brain
is the most important organ in our body and when it gets damaged, it can affect us severely. If
you want your brain to function at its best, here are 11 things you should stop doing.
No1: Too much screen time There is much talk about the negative
effects of social media. But, too much screen time in general can harm our brains. It actually
damages brain cells in several different areas of the brain. In the first place, a lot of screen
time damages the frontal lobe, where processing and higher-order thinking occurs. Too much screen
time every day results in changes in the area of the brain where all cognitive functioning
happens. It affects our attention span, thinking and learning abilities from the earliest age.
No2: Too much sugar Too much sugar for a long period
disturbs our body’s capacity to absorb proteins and nutrients. This results in a condition called
malnutrition, which deters brain’s growth. All of this happens because there are not adequate
nutrients in the blood and it does not deliver enough nutrients to our brain, which cannot
develop properly. Excessive intake of sweets can harm your memory and thinking ability, so choosing
antioxidant-rich sweets like dark chocolate is a wise choice for both your brain and your weight.
No3: Too much bad news Did you know that bad news
is also bad for your brain? Bad news excites our nervous system. When you absorb too much bad news,
your body unintentionally goes into flight or fight mode, because it becomes overly excited.
Flight or fight mode involves the activation of stress hormones. If this happens too often
or it lasts for a long time, your brain begins to feel negative consequences. Our
thinking processes change. We stay in a state of negativity long after the bad news consumption.
No4: Not enough exercise Our brain develops through movement
from the earliest childhood. And when we are grown up, exercise can greatly improve the functioning
of our brains. This happens because exercise helps get more oxygen to your brain. It also releases
growth-promoting hormones. Some research indicates that the longer you go without regular exercise,
the more likely you are to experience loss of memory, language, problem-solving and other
thinking abilities that are severe enough to interfere with daily life. Aerobic exercises,
such as walking, running or swimming are connected to improvements in cognitive
functioning. Even daily brisk walks may help delay mental aging by as much as five to seven years.
No5: Poor sleep quality
Poor sleep quality leaves the brain exhausted and unprepared for the things that it needs
to do during the day. It should come as no surprise that sleep deprivation gets in the
way of the brain’s ability to perform. If you don’t get enough sleep, the neuroreceptors in
your brain lose their sensitivity. That results in impaired cognitive functions of thinking,
reasoning, and problem-solving. In addition, poor sleep quality leads to a reduction in brain tissue
in the areas of the brain where the functions of planning, reasoning and intelligence are located.
No6: Too much loud noise In the modern world, our ears have a lot to
endure. There is constant exposure to loud noises: subway’s roaring, cars honking, music in the
supermarket, even in your headphones. Loud noises might damage your hearing abilities permanently.
It can result in some brain problems such as loss of memory and damage to your brain tissue. A study
conducted at John Hopkins University found that hearing-impaired people have a 30 – 40% higher
risk of cognitive deterioration. No7: Bad eating habits
When thinking about the effects of bad dieting habits on the brain, we need to take into account
several things, such as eating too much food, skipping breakfast, eating too much salt and
eating too much junk food. All of these habits alter the way our brains receive nutrients and
can lead to cognitive impairment. For example, one study showed that the participants, who were
overweight, had a 22% higher deterioration of their cognitive functions than the slimmer ones.
No8: Loneliness Many people enjoy their alone time. But,
we are not talking about that. When we say that loneliness affects our brains negatively,
we mean that awful feeling of loneliness that can happen even when surrounded by other people,
if you cannot relate to them. The feeling of loneliness actually causes stress and inflammatory
processes in the brain. This stress that occurs as a result of social isolation can make you more
susceptible to having a stroke. No9: Watching reality TV shows
We probably all heard the same warning as kids: “That TV will rot your brain!” It turns out that
warning can be very true. Especially if we are talking about reality shows. Reality TV is like
junk food for your brain. Neuroscientists have demonstrated that prolonged reality television
viewing alters children's brain structure. This supports the findings of several previous studies
that show that too much reality TV leads to lower verbal IQ, as well as increased aggressiveness.
No10: Too much multitasking In modern times, multitasking is
mostly inevitable. We often juggle between doing paperwork, talking on the phone and ordering
lunch. But, it turns out that multitasking can be very damaging to our brains. The effect is
even worse if there are multiple sources of digital information bombarding you. People
who often multitask have more problems with their memory and attention span in comparison
to people who complete one task at a time. Multitasking can even lead to a temporary
drop of IQ scores by 15 percent. No11: Not drinking enough water
80 percent of the brain is made up of water. There's a reason why you can't focus on various
tasks when you're dehydrated. Studies have revealed that not drinking enough water causes
brain tissue to shrink. This interferes with your ability to perform executive functions
like planning and processing of vision and spatial information. Our brain cells appear to dry out and
contract when we don’t drink enough water. Have you recognized the negative effects of
these habits on your brain? Let us know in the comment section.
