bad habits

Our habits reflect to our health, and there are certain bad habits that you should avoid doing. To begin with, there are many activities that we do every day in our daily life from morning till night. As we grow older, our body starts to get weaker and they cannot handle the bad habits from our routine any longer. When that happens, it will result in sickness or disease that will affect to our health or even life. Today, we will look into some bad habits that will damage your brain if you do it way too often. Check out those habits and let’s see how many that you can relate to.

1Alcohol Consumption

The effects of alcohol on the brain depends on how much and how often a person drinks and their age. Heavy drinking is never good for the body especially the brain, and the result is bad in both long-term and short-term. Moderate drinking leads to short-term impairment that you can tell when you cannot fully control your speech and actions when you are drunk.

The long-term impairment that alcohol does to our brain is even much more to count. That includes difficulty in walking, blurred vision, slurred speech, slowed reaction times, and impaired memories. And alcohol can also does damage to the brain of the baby if you consume it during stage of pregnancy. Drinking during pregnancy can lead to a range of physical, learning, and behavioral effects in the developing brain. For both the mother and the baby, of course.

2Exposure In Air Pollution

Our brain is the largest oxygen consumer in our body because brains control almost everything in the body. When you inhale polluted air on a daily basis without protection, there will be bad consequences. The main one is the decrease of the supply of the oxygen to the brain which leads to the decrease of brain efficiency. Also, polluted air also damages your body and your respiratory system as well which is very harmful to your health.

The solution is to wear mask when you go or walk pass the area with polluted air like factories. Smoke from car is also bad to inhale because the amount of harm is not any different. Try to live in a healthy area, or cover your nose to avoid direct contact or inhale the polluted air.

3Head Covered While Sleeping

Each person has different sleeping habit from one another, some are good while the others are not. So when you cover your head when you sleep, there will be an increase of the concentration of carbon dioxide. It also decrease the concentration of oxygen that may lead to brain damaging effects. As a matter of fact, we should not cover our faces while sleeping because it blocks the incoming of oxygen. It also makes you inhale your own carbon dioxide which you exhale in the same blanket that you cover. So no matter how cold you get, limit the blanket up to your neck or your nose.

4High Sugar Consumption

Too much sugar is never good, too much of anything is never good actually. Too much sugar will interrupt the absorption of proteins and nutrients causing malnutrition and may interfere with brain development. That will lead to slow progress of the brain as well as regular headache from the slow brain development.

5Lacking In Stimulating Thoughts

Thinking is the best way to train our brain, and mental activity or neurological stimulation can enrich the mind. Education, occupation, social, and leisure activities are all important contributors to mental stimulation which leads to the increase of blood flow, oxygen, and nutrients. It also acts as a signal which promotes the expression of brain-derived neurotrophic growth factor.

Without or lacking in brain stimulation thoughts can cause brain shrinkage which affects to your performance as a whole. You will become less active, more quiet, slow in making decision or interpretation, and many more. Then, it will result in depression and boredom due to the shrinkage of mechanism neurons and the brain. Once you are not as active as you used to be, depression will be the first thing to happen.

There are many ways to stimulate your brain, and even doing exercise is good for brain. Running and swimming are great for the health of the brain because they increase your heart rate. When your heart rate increase, the body pumps more blood to your brain which keep it healthy and active. Playing games or hanging out with friends involve with a lot of speech and thinking which also helps.

6Lack Of Sleep or Sleep Deprivation

The only time that our busy brain gets to rest is when we sleep which is why sleeping is important. That is why when we get to sleep early at night, we tend to feel fresh in the morning. However, the deprivation from sleep as a habit will accelerate the death of brain cells. Even worse, sleep deprivation can also lead to a permanent loss of brain cells which is very bad.

In the study, the researchers found that sleep deprivation makes it difficult for brain cells communicate effectively. When that happens, it can lead to temporary mental lapses that affect memory and visual perception. In other words, you will find it harder from day to day to recognize or see things clearly without enough sleep. The more dead cells we have in our brain, the less it functions.

7Over Eating

There are many bad consequences result from over eating because eating too much is never good. Eating too much always results in overweight or increase in cholesterol if you consume unhealthy food on a daily basis. As for the brain, over eating will cause hardening of the brain arteries which leads to a decrease in mental power.

If you look into a broader sense, you will gain weight when you eat too much. When you gain weight, you will feel bad or stressed out because you worry about your appearance. Eating too much will also lead to irregular sleeping habit, you will get hungry and eat more when you can’t sleep. It is a very unhealthy cycle that damages your health little by little which is something you should consider changing.

8Skipping Breakfast

We always hear the phrase that says ‘Breakfast is the most important meal of the day.’ That is actually true because first of all, you have no meal in your stomach while sleeping for the whole night. So you need to eat to bring energy to yourself as you work or study in the morning. Then the coffee lovers will say nah all I need is a cup of coffee in the morning. Now listen to this.

When you have the habit of not having breakfast, you will start to have a lower blood sugar level. The longer your habit lasts, the more symptoms will appear. That includes headache, restlessness, fatigue, and you will start to feel heavy in the head and get tired easily. Low blood sugar level leads to an insufficient supply of nutrients to the brain causing brain degeneration.

The advice is to have breakfast regularly no matter if the amount is big or small. If you get up late and have nothing left is the fridge, at least have some fruit. The idea is to fill something in your stomach instead of just water or coffee for the whole morning. Skipping breakfast once in a while is okay, but doing so too often is one bad habit to change.


We all know that smoking is bad for your body especially the lungs, but smoking also damages the brain. As we all know, cigarettes contain nicotine that is a substance that is both addictive and dangerous. Nicotine also contains some substances that cause multiple brain shrinkage which is absolutely bad. That is why many smokers have a high chance of having Alzheimer as they get old.

10Working Your Brain During Illness

When you are not feeling well like having a headache, flu, and other types of sickness, you should rest. Working hard or studying hard with sickness can lead to a decrease in effectiveness of the brain. It is not different from over using the brain more than you should when it is time to rest. The harder you try, the less effective you will become. If you develop that into a habit, it can also cause brain damage because the brain does not get to rest.

You might have a deadline to finish or an important work to do, but always take some time to rest. Once you feel better, you can do your work with more satisfying result compared to when you are sick. Remember to always let your brain rest because once you use it too much, it will never work the same way again. You cannot do a 5 years of rest to compensate the time you overuse the brain, let’s not forget that.
