Whenever we study and learn, several things happen in our brain: new cells generate, new connections are created between cells, and existing connections between certain cells are strengthened or removed. Studies show that stimulating environment and the presence of beta-endorphin (the good mood hormone) lead to good cell growth in our brains. The Neurological Foundation of New Zealand says these factors affect brain health:

Regular physical exercise. This protects the brain and the way it processes information. Exercise boosts levels of brain-protective chemicals and reduces stress.

Adequate sleep. A good night’s sleep recharges the brain and allows the body to rest and heal. Our brain consolidates memories while we sleep. Inadequate sleep affects the way our brain cells function and can increase the risk of stroke and depression. About seven to nine hours of sleep a night is ideal.

Balanced diet. Your diet should be low in cholesterol and saturated fat. Studies show that foods rich in omega-3 fatty acids (e.g., fish) are good for the brain.

Social connections. Friendships and social networks are important as we age. Good mood hormones help us create new brain cells and keep them healthy.

Mental workout. Use it or lose it! Keeping the brain active and challenged increases its vitality, generates new brain cells, and bolsters connections and reserves.
