10 Habits That Could Damage the Brain

Updated on February 14, 2024

The Brain

The brain stands as the body's most crucial organ, overseeing all functions and transmitting electrical impulses that regulate bodily processes. However, what occurs when the brain experiences malfunction or degeneration?

10 habits that contributes to the decline in brain function:

1. Skipping Breakfast

Breakfast is considered to be the most important meal of the day and should not be skipped. Eating a good and hearty breakfast enables you to be more focused and productive.

People who do not take breakfast tend to have a lower blood sugar level that can lead to an insufficient supply of nutrients and vitamins to the brain. And this can cause brain degeneration.

2. Over-eating

This can cause the hardening of brain arteries which can lead to a decrease mental power or reduced brain function. High caloric intakes can double the risk of memory loss or Mild Cognitive Impairment (MCI).

3. Smoking

Smoking can cause multiple brain shrinkage and this may lead to Alzheimer disease, which is a progressive neurologic disease of the brain that slowly destroys memory and thinking skills.

Smoking can block the carotid artery in our brain, thus the blood supply to the brain are cut off.

4. Lack of Sleep

Sleep allows our brain to rest. Sleep also gives the brain a chance to regenerate important neuronal connections in the brain that may have deteriorated from day’s activity. Deprivation from sleep will accelerate the chance of death of brain cells.

5. Working during sickness

Sickness/illnesses are warnings that your body has overworked and need to regain and catch up with the energy lost. One should rest when you feeling sick.

Working your brain when you are sick can decrease the effectiveness of the brain and may also cause brain damage.

6. PollutedAir

Did you know that the brain is the largest oxygen consumer in our body? Inhaling this polluted air reduces the supply of oxygen to the brain, and results to the decrease in brain efficiency.

This also contributes to memory loss. Exposure to polluted air contributes to the early decline of brain function.

7. High Sugar Intake

High intake of sugar will interrupt the absorptions of nutrients and proteins. This can cause malnutrition and this may interfere with brain development.

A diet high in sugar reduces the production of Brain-derived Neurotrophic Factor (BDNF), a chemical found in brain. Without this chemical BDNF, the brain can’t form new memories thus resulting to loss of learning or remembering much of anything.

8. Lack of stimulating thoughts

Lack of stimulating thoughts has also bad effects to our brain. This can cause brain shrinkage. Thinking is one of the best ways to train our brain so if you want to treat your brain right, have inspiring and motivating thoughts.

9. Talking Occasionally

Are you a silent-type kind of person – the kind who rarely talks? It’s bad because it can damage and shrink your brain. You need to speak your thoughts and ideas as well. Intellectual conversations will promote the efficiency of the brain and will help the brain function right.

10. Covering the head while sleeping

Do you cover your head while sleeping? Sleeping with this kind of habit increases the concentration of carbon dioxide and thus, decreases the concentration of oxygen that may lead to brain damaging effects.


Eat the right kind of food to enhance the maximum potential of your brain. Start with the berries. Take good care of your health because it is your only wealth.
