Research has been consistent in proving the importance of sleep in repairing the brain and also in the consolidation of long-term memory. 7-8 hours of sound sleep is necessary for adults. Indeed, you yourself may have experienced the detrimental effects of sleeping less. How did you feel, both psychologically and physically, on the days when you slept very less number of hours? It was your brain’s way of communicating to you the struggle that it is going through.
When we exercise, blood flow increases throughout the body. As a result, brain will receive enough amounts of nutrients and oxygen. Low availability of these two elements can fasten cognitive decline.

Stress increases the release of cortisol. Consistent presence of this hormone in our system can damage neurones. In fact, learning processes and memory consolidation will also get hindered.
![Avoid Junk Foods for Brain Health]()
Important nutrients such as vitamin B, antioxidants, omega-3 fatty acids are key elements for brain health. Some people replace foods that provide these items with processed meals or junk foods which can negatively impact the structure of our brains. Sugary snacks should also be avoided.
Social interactions are essential to keep our brains active and sharp. If you remain in a solitary space for too long, brain’s activity can become dull. When we talk with our friends, make some jokes and laugh for a while, happiness hormones such as dopamine, serotonin etc will be released. These hormones are very important for maintaining emotional and psychological balance.
When we wake up in the morning, our brain will be waiting for a steady supply of energy. Of course, after an overnight fast, your brain deserves it. What happens when you deny your brain this necessity? Brain fog and lack of concentration. So, always remember the importance of breakfast and try your best not to skip it.
Numerous studies have proved that excessive intake of alcohol, drugs and smoking can slowly damage brain nerves. In fact, not just the brain, our overall health and longevity itself will be negatively affected due to these addictions.
Did you know that almost 75% of our brain is made up of water? So, there is a direct link between hydration and cognitive performance. Whatever task that you are engaged in, always remember to keep a bottle of water near you.
