9 Ways to Make Yourself Smarter
Exercise encourages your brain to work at optimum capacity by causing nerve cells to multiply, strengthening their interconnections and protecting them from damage. During exercise nerve cells release proteins known as neurotrophic factors. One in particular, called brain-derived neurotrophic factor (BDNF), triggers numerous other chemicals that promote neural health, and directly benefits cognitive functions, including learning.
2. Animal-Based Omega-3 Fats
Docosahexaenoic acid, or DHA, an omega-3 fat, is an essential structural component of both your brain and retina. Approximately 60 percent of your brain is composed of fats—25 percent of which is DHA. DHA is also an essential structural ingredient of breast milk, which is believed to be a major reason why breastfed babies consistently score higher on IQ tests than formula-fed babies.
Sleep is not only essential for regenerating your physical body, but it is imperative for reaching new mental insights and being able to see new creative solutions to old problems. Sleep removes the blinders and helps "reset" your brain to look at problems from a different perspective, which is crucial to creativity.
4. Coconut Oil
One of the primary fuels your brain needs is glucose, which is converted into energy. Your brain actually manufactures its own insulin to convert glucose in your bloodstream into the food it needs to survive.
5. Vitamin D
Activated vitamin D receptors increase nerve growth in your brain, and researchers have also located metabolic pathways for vitamin D in the hippocampus and cerebellum of the brain, areas that are involved in planning, processing of information, and the formation of new memories.
6. Optimize Your Gut Flora
Your gut is your "second brain," and your gut bacteria transmits information to your brain via the vagus nerve, the tenth cranial nerve that runs from your brain stem into your enteric nervous system (the nervous system of your gastrointestinal tract). There is a close connection between abnormal gut flora and abnormal brain development, and just as you have neurons in your brain, you also have neurons in your gut -- including neurons that produce neurotransmitters like serotonin, which is also found in your brain and is linked to mood.
7. Vitamin B12
Vitamin B12, or rather a lack thereof, has been called the "canary in the coalmine" for your future brain health, and recent research has bolstered the importance of this vitamin in keeping your mind sharp as you age. According to the latest research, people with high levels of markers for vitamin B12 deficiency were more likely to score lower on cognitive tests, as well as have a smaller total brain volume,ix which suggests a lack of the vitamin may contribute to brain shrinkage.
8. Listen to Music
It's long been theorized that listening to music may boost your brainpower; you've probably heard of this with the "Mozart Effect," which suggests listening to classical music can make you smarter.
9. Challenge Your Mind
One of the simplest methods to boost your brain function is to keep on learning. The size and structure of neurons and the connections between them actually change as you learn. This can take on many forms above and beyond book learning to include activities like traveling, learning to play a musical instrument or speak a foreign language, or participating in social and community activities.
