1. No Breakfast
Those who do not eat breakfast have lower blood sugar levels, which consequently supply of nutrients to the brain becomes less.
Too much to eat, let alone a high fat content, can result in hardening of the blood vessels of the brain due to accumulation of fat in the blood vessel wall. Consequently the ability of the brain will decrease.
Substances in tobacco that is inhaled will cause rapid brain shrinkage and may lead to Alzheimer's disease.
4. Consuming too much sugar
Consumption of too much sugar will cause disruption of the absorption of protein and nutrients, causing nutritional imbalances that would 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 that can decrease the efficiency of the brain.
6. Sleep Deprivation
The brain needs sleep as a time to rest and restore capabilities. Sleep deprivation in the long term will accelerate the destruction of brain cells.
7. Head covered while sleeping
The habit of sleeping with the head covered increases the concentration of carbon dioxide and decrease concentration of oxygen that may lead to brain damaging effects.
8. Using mind when sick
Working too hard or forced to use our minds while studying with sickness may lead to reduced effectiveness of the brain and can damage the brain.
9. Less stimulating thoughts
Thinking is the most appropriate way to train our brain. Lack of stimulation in the brain can lead to wrinkle our brains.
10. rarely communicate
Communication is needed as one means of spurring ability of the brain. Communicate intellectually can trigger brain efficiency. Rare intellectual ability to communicate will cause the brain to be poorly trained.
