A Few More Tips On How To Improve Your Intelligence
- Good nutrition means healthy life, body and mind. Eat ‘brain foods’ rich in vitamins, carbohydrates and amino acids.
- Exercise regularly, to improve the supply of blood and oxygen to the brain.
- Have a good night’s sleep. Sleep deprivation can impair the brain areas of concentration, alertness, memory (short and long-term), and problem-solving.
- Moderate alcohol consumption. Alcohol abuse can impair the cognitive abilities of the brain. On the other hand, moderate drinking can help improve its functioning.
- Quit smoking. The toxins found in cigarettes are known to cause long-term damage to the cognitive thinking.
- Meditate. Meditation is a stress-relief technique that can help improve the attention, alertness and creativity.
