1. Not having breakfast:

People who do not take breakfast are going to have a lower blood sugar level. This leads to an insufficient supply of nutrients to the brain causing brain degeneration.

2. Abnormal eating / Overeating:

It causes hardening of the brain arteries, leading to a decrease in mental power.

3. Active/ Passive Smoking:

It causes multiple brain shrinkage and may lead to Alzheimer disease.

4. High Consumption of Sugar items:

Too much sugar will interrupt the absorption of proteins and nutrients causing malnutrition and may interfere with brain development.

5. Air and Noise Pollution:

The brain is the largest oxygen consumer in our body. Inhaling polluted air decreases the supply of oxygen to the brain, bringing about a decrease in brain efficiency.

6. Sleep Deprivation:

Sleep allows our brain to rest. Long term deprivation from sleep will accelerate the death of brain cells.

7. Full face covered while sleeping:

Sleeping with the head covered, increases the concentration of carbon dioxide and decrease concentration of oxygen that may lead to brain damaging effects.

8. Strain your brain during illness:

Working hard or studying with sickness may lead to a decrease in effectiveness of the brain as well as damage the brain.

9. Idle Brain:

Thinking is the best way to train our brain, lacking in brain stimulation thoughts may cause brain shrinkage.

10. Talking Rarely:

Intellectual conversations will promote the efficiency of the brain.
