According to world health organization following habits damage brain severely:

1. No Breakfast :- It lowers blood sugar level. which leads to insufficient supply of nutrients to the brain causing brain degeneration.

2. Overreacting – Brain arteries hardens, 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 interrupts the absorption of proteins and nutrients causing malnutrition also interferes with brain development.

5. Air Pollution :- Brain is the largest OXYGEN consumer in our body. Inhaling polluted air decreases the supply of oxygen to the brain, Lower Oxygen - decrease in 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.

9. Lack of Positive Thinking :– 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.
