1. No 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. Overeating : It causes hardening of the brain arteries, leading to a decrease in mental power.
3. Smoking: It causes multiple brain shrinkage and may lead to Alzheimer disease.
4. High Sugar consumption: Too much sugar will interrupt the absorption of proteins and nutrients causing malnutrition and may interfere with brain development.
5. Air 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. Head 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. Working 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. Lacking in stimulating thoughts: 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.
