Human health depends largely on the brain’s ability to function properly. The brain is the most important organ in the body, as it controls all functions, including the ability to heal. However, when it comes to health, the brain is largely ignored. There are certain things one can do to help improve brain function, including nutritional intake, brain training, meditation and other brain exercises.
According to an article published by Harvard Medical School, what one eats directly affects the function and structure of the brain and, ultimately, one’s mood.
Like a precision-built luxury car, the human brain functions optimally when it gets only the best, high-powered fuel. Consuming high-quality foods that contain a lot of minerals, vitamins, and antioxidants, serves to nourish the brain and protect it from oxidative stress.
Just as that precision-built luxury car will not run well on inferior fuel, the brain can actually be damaged if one ingests anything other than premium fuel. Eating refined sugars and highly processed foods can harm the brain. In addition to harming the body’s ability to regulate insulin, they promote oxidative stress and inflammation.
Multiple scientific studies have found a relationship between a diet high in refined sugar and negatively impaired brain function. Additionally, there has been a worsening of the symptoms of certain mood disorders, such as depression.
Exercise prompts the human brain to work at optimum capacity by prompting nerve cells to multiply, which strengthens their interconnections and protects them from damage. When one exercises, his or her nerve cells release neurotrophic factors, which are types of proteins. One of these proteins in particular, triggers numerous other chemicals that promote brain health and that positively benefit cognitive functions, including one’s ability to learn.
Exercise also results in:
- The production compounds that protect the brain’s nerves
- Increased blood flow to the brain
- Improved development and survival of neurons
- Decreased risk of cardiovascular diseases such as stroke
Sleep is essential for creativity and problem solving. Another study conducted by Harvard Medical School suggests that people are as much as 33% more likely to infer connections between distantly related ideas after sleep, but that most people do not realize their performance has improved. Sleep can enhance memory and help improve brain function with regard to challenging skills. The study found that one night’s sleep lasting from 4 to 6 hours can positively impact one’s ability to think clearly the following day.
One of the easiest ways to boost brain function is to continually strive to learn new things. The structure and size of neurons, as well as the connections between them change as one learns.
Learning is not limited to things one necessarily learns from books. It can also include such activities as traveling to new places, learning how to play, write or sing music, learning to speak a language other than one’s own or becoming a part of community and other social activities.
Challenging the brain with various mind training activities and exercises can keep the brain fit as one ages. These exercises do not have to be elaborate. They can be as simple as trying to recall the names of all of the states, or attempting to recall as many names as possible that begin with a certain letter of the alphabet. Crossword puzzles are great ways to exercise the brain, as are playing the types of board games, such as chess, that require contemplation.
Research suggests that even surfing the Internet activates specific regions in the brain that are related to complex reasoning and decision-making. Unlike passively viewing television, surfing the web is more engaging and can actually help improve one’s brainpower.
