Brain (human brain) is the most important as well as a complicated part of your body. It has a great ability to send and receive an enormous and unlimited amount of information. Here are some amazing brain health facts which you heard earlier.


Good things for the brain


Healthy Eating

A recent study found that older adults who followed the Mediterranean diet—rich in vegetables, fruit, whole grains, and fish—retained more brain cells than older adults who didn’t follow the diet.

A study found that compounds in extra-virgin olive oil, an important part of the Mediterranean diet, “may reduce brain inflammation as well as prevent the buildup of plaque and neurofibrillary tangles, which are suspected to contribute to the symptoms of Alzheimer’s,” Palinski-Wade says.

In addition, “DHA and EPA omega-3 fatty acids from salmon and other fish have been found to be protective to the brain and contribute to improved memory function in older adults,” she says.

Your brain uses 20 percent of the oxygen and blood in your body.

Dream

Brain activity during dreaming increases to a similar level as when we are awake, says behavioral sleep therapist Richard Shane, Ph.D. That may help you solve problems and boost your ability to cope with struggles and stress. A Harvard Medical School study showed that participants who achieved REM sleep (when dreaming usually happens) were better able to detect positive emotions in other people, while those who did not were more sensitive to negative emotions. The study’s author suggests that dreams help the brain process negative emotions safely. If we fail to dream, then we fail to let go of these emotions and are left in a constant state of anxiety.

Dreams are believed to be a combination of imagination, pshycological factors, and neurological factors. They prove that your brain is working even when you are sleeping.

Social Interaction 

A 2015 review of previously published research showed that less frequent social interaction was associated with a higher incidence of new cases of dementia. Volunteering, visiting with friends and family, and staying active in social groups can help keep your brain healthy as you age.

The human brain will grow three times its size in the first year of life. It continues to grow until you’re about 18 years old.

Gum Chewing 

In a 2013 study in the British Journal of Psychology, researchers had two groups of people listen to a 30-minute recording that included a sequence of numbers. After listening, the participants were asked to remember the sequence. But only one group chewed gum—and people in that group had higher accuracy rates and faster reaction times than the non–gum chewers. The researchers say that chewing gum increases the flow of oxygen to regions of the brain responsible for attention.

Vacation 

Studies show that time off helps you be more productive. “Our brains are not machines that can work endlessly without a glitch,” says psychologist Deborah Serani, PsyD, the author of Depression in Later Life and a professor at Adelphi University. Downtime“ allows the regulatory systems of your brain to chill out,” she says

Laughter

 “There’s a long history of research showing that laughter increases feel-good hormones dopamine and serotonin,” Serani says. This, in turn, decreases pain and improves resiliency.

Another brain health facts are Exercise

In one study of adults ages 65 and older, those who exercised four times a week cut the risk of dementia in half compared with those who either weren’t active at all or were active only one day a week. Plus, “exercise at every age has been shown to improve memory, concentration, and other cognitive functions,” says Palinski-Wade. This appears to be linked to an increase in circulation, bringing oxygen and nutrients to the brain while also helping remove waste.
