10 Dangerous Brain-Damaging Habits to Stop Immediately

The brain is responsible for all body functions, so you need to keep it safe.

Here are 10 common practices to help your brain work at its optimum performance:

Stop Being Bored

Neuroplasticity is the ability to think differently, make new connections and retain memories. The brain, just like any other organ will atrophy without intellectual stimulation.

Skipping Breakfast

Skipping breakfast in the morning will make you sluggish, but also your brain is revving up for another busy day. Lack of nutrition causes slow metabolism and the brain can permanently shut down some functions.
A study conducted in Japan says people who routinely skip breakfast are 36% more likely to suffer a brain hemorrhage. Moreover, eating breakfast restrain cravings and over-eating later in the day.

Cell Phones

Radiation exposure is harmful to human health. Put away your cell phone when going to bed because it is distracting and can disrupt sleep.
Cell phone radiation can cause headaches and confusion. Limit cell phone use by using a headset and put it far away from you.

Working Through Illness

When feeling sick, rest and eat properly because your immune system functions as full capacity in order to fight the infection.


Overeating can cause excess weight and obesity. Often, people eat more than necessary and consume food that is not nutritive. Thus, the body remains hungry and we eat more. Foods that are poor in nutrients do not help the brain function at its best. Chronic obesity is associated with low brain volume and dementia.


People should be social and talk to each other. Oral communication uses a different part of the brain than written, so you need to talk more to other people so you can exercise this part of the brain. Depression and anxiety, which are products of the brain, can be caused by lack of social interaction.

Lack of Sleep

We must acknowledge the value of regular, good quality and adequate amounts of sleep. The brain is equally active while sleeping as while awake. Highly important activities occur while sleeping: the long-term memory storage and eliminating toxins.
When sleep deprived, the memory suffers and there is a greater risk of neurodegenerative disease because of plaque accumulation.


A research from 2004 says that smoking cigarettes cause damage to neuronal viability and cell membranes in the midbrain and on cell membranes of the cerebellar vermis. These brain regions are involved in fine and gross motor functions and balance and coordination.
Try to quit smoking and most of any damage caused by smoking will be repaired over a short time.


Sugar is bad for every system in the body, including the central nervous system. Try to avoid too much sugar intake. Many studies have shown that regular excess sugar ingestion is related to Alzheimer’s disease.

Air Pollution

Air pollution can only be avoided if wearing an oxygen mask all the time. The air we breathe all the time is full of dangerous particles that affect all facets of the human condition.
Air pollution causes brain shrinkage and cognitive impairment, among other dangerous conditions. What we breathe and absorb through the skin moves through the bloodstream, spreading to every organ, including the brain.
There are many researches that show air pollution is related to the development and exacerbation of neurodegenerative diseases like Parkinson’s and Alzheimer’s.
