Science Says Walking In Nature Changes The Brain

Science Says Walking In Nature Changes The Brain

Want to live a happier life and have a more productive work day? Take the scenic route to work. The concrete commute that most city dwellers experience on the daily may be having a larger impact on the psyche than you think. Beyond the concrete jungle that we more and more fail to escape on a regular basis exists an environment that may help you combat stress, depression, and anxiety.

Walking In Nature Helps Depression And Anxiety

The isolation of being locked up in offices and high rise condominiums is being linked to psychological disorders including depression, anxiety and a short attention span at work. New York Times article, How Nature Changes the Brain by Gretchen Reynolds, found that people who live in cities spend more time ‘brooding’, a term meaning a renumeration of thoughts in your mind as to what is wrong with yourself and your life. The study compared those who lived in high density urban settings to those who had more exposure to greenery and trees.

Walking In Nature Improves Your Attention and Focus

So what if you don’t have a park on the route to work or cannot give up the highway commute? There is still hope. The Journal of Environmental Psychology suggests that even small mental breaks viewing nature can help aid off psychological issues such as reduced attention span. The study looked at subjects that viewed either concrete or green spaces and found that the ones who viewed the natural environment made less errors and were more consistent responding to given tasks. Living and working surrounded by thousands of people and concrete drains your mental resources that are critical for attention. While in opposition, viewing trees, parks, and green spaces on a regular basis, helps create a more calm and active mind.

Viewing Nature Helps Your Mind Escape Everyday Concerns

So how does nature help with depression and anxious feelings and give us a greater sense of focus? From a logical perspective it makes sense that being surrounded by thousands of people, heavy traffic, and concrete would make us feel more anxious, and unhappy. But why would nature have such a large effect on our brains? Nature gives the brain a sense of calmness and peace. The presence of trees, water, and open spaces of greenery transitions the mind into feeling an escapement from everyday concerns. It brings the simplicity back into life. Nature literally changes the brain.

And not only are the people who have more exposure to natural settings mentally healthier, but they also enjoy a higher quality of physical health as well. A convincing example in the New Yorker, What a Tree is Worth, by Alex Hutchinson,  showed that patients given hospital rooms that looked over spaces with trees as opposed to a brick wall, recovered faster. In fact , researchers are discovering that surrounding yourself with nature can be one of the most powerful stress-relievers out there.

As unlikely as it is to take a twenty minute detour for a scenic route or to move to a park surrounded area, there are small changes that you can implement into your life today. Change your desktop background to outdoor scenery or hang visual art of the sky and ocean on your wall. Spend more of your breaks outside, plan more trips to the park or runs along the water. Vote in favour of green roofs, and of course make an effort to get into nature and enjoy it. We tend to complicate the cures for anxiety and depression when in fact being in a calm and natural environment may just be what you need.

12 Best Foods That Improve Memory and Brain Health

12 Best Foods That Improve Memory and Brain Health

Nutrition plays a vital role in brain function and staying sharp into the golden years. Personally, my husband is going through medical school, which is like a daily mental marathon. Like any good wife, I am always looking for things that will boost his memory fortitude so he does his best in school.

But you don’t have to be a med student to appreciate better brainiac brilliance. If you combine certain foods with good hydration, proper sleep and exercise, you may just rival Einstein and have a great memory in no time.

I’m going to reveal the list of foods coming out of the kitchen that can improve your memory and make you smarter.

Here are 12 best brain foods that improve memory and brain power:

1. Nuts

The American Journal of Epidemiology published a study linking higher intakes of vitamin E with the prevention on cognitive decline.[1]

Nuts like walnuts and almonds (along with other great foods like avocados) are a great source of vitamin E.

Cashews and sunflower seeds also contain an amino acid that reduces stress by boosting serotonin levels.

Walnuts even resemble the brain, just in case you forget the correlation, and are a great source of omega 3 fatty acids, which also improve your mental magnitude.

2. Blueberries

Shown in studies at Tuffs University to benefit both short-term memory and coordination, blueberries pack quite a punch in a tiny blue package.[2]

When compared to other fruits and veggies, blueberries were found to have the highest amount of antioxidants (especially flavonoids), but strawberries, raspberries, and blackberries are also full of brain benefits.

3. Tomatoes

Tomatoes are packed full of the antioxidant lycopene, which has shown to help protect against free-radical damage most notably seen in dementia patients.

4. Broccoli

While all green veggies are important and rich in antioxidants and vitamin C, broccoli is a superfood even among these healthy choices.

Since your brain uses so much fuel (it’s only 3% of your body weight but uses up to 17% of your energy), it is more vulnerable to free-radical damage and antioxidants help eliminate this threat.

Broccoli is packed full of antioxidants, is well-known as a powerful cancer fighter and is also full of vitamin K, which is known to enhance cognitive function.

5. Foods Rich in Essential Fatty Acids

Your brain is the fattest organ (not counting the skin) in the human body, and is composed of 60% fat. That means that your brain needs essential fatty acids like DHA and EPA to repair and build up synapses associated with memory.

The body does not naturally produce essential fatty acids so we must get them in our diet.

Eggs, flax, and oily fish like salmon, sardines, mackerel and herring are great natural sources of these powerful fatty acids. Eggs also contain choline, which is a necessary building block for the neurotransmitter acetylcholine, to help you recall information and concentrate.

6. Soy

Soy, along with many other whole foods mentioned here, are full of proteins that trigger neurotransmitters associated with memory.

Soy protein isolate is a concentrated form of the protein that can be found in powder, liquid, or supplement form.

Soy is valuable for improving memory and mental flexibility, so pour soy milk over your cereal and enjoy the benefits.

7. Dark Chocolate

When it comes to chocolate, the darker the better. Try to aim for at least 70% cocoa. This yummy desert is rich in flavanol antioxidants which increase blood flow to the brain and shield brain cells from aging.

8. Foods Rich in Vitamins: B vitamins, Folic Acid, Iron

Some great foods to obtain brain-boosting B vitamins, folic acid and iron are kale, chard, spinach and other dark leafy greens.

B6, B12 and folic acid can reduce levels of homocysteine in the blood. Homocysteine increases are found in patients with cognitive impairment like Alzheimer’s, and high risk of stroke.

Studies showed when a group of elderly patients with mild cognitive impairment were given high doses of B6, B12, and folic acid, there was significant reduction in brain shrinkage compared to a similar placebo group.[3]

Other sources of B vitamins are liver, eggs, soybeans, lentils and green beans. Iron also helps accelerate brain function by carrying oxygen. If your brain doesn’t get enough oxygen, it can slow down and people can experience difficulty concentrating, diminished intellect, and a shorter attention span.

To get more iron in your diet, eat lean meats, beans, and iron-fortified cereals. Vitamin C helps in iron absorption, so don’t forget the fruits!

9. Foods Rich in Zinc

Zinc has constantly demonstrated its importance as a powerful nutrient in memory building and thinking. This mineral regulates communications between neurons and the hippocampus.

Zinc is deposited within nerve cells, with the highest concentrations found in the hippocampus, the part of the brain responsible for higher learning function and memory.

Some great sources of zinc are pumpkin seeds, liver, nuts, and peas.

10. Gingko Biloba

This herb has been utilized for centuries in eastern culture and is best known for its memory boosting brawn.

It can increase blood flow in the brain by dilating vessels, increasing oxygen supply and removing free radicals.

However, don’t expect results overnight: this may take a few weeks to build up in your system before you see improvements.

11. Green and Black Tea

Studies have shown that both green and black tea prevent the breakdown of acetylcholine—a key chemical involved in memory and lacking in Alzheimer’s patients.

Both teas appear to have the same affect on Alzheimer’s disease as many drugs utilized to combat the illness, but green tea wins out as its affects last a full week versus black tea which only lasts the day.

12. Sage and Rosemary

Both of these powerful herbs have been shown to increase memory and mental clarity, and alleviate mental fatigue in studies.

Try to enjoy these savory herbs in your favorite dishes.

When it comes to mental magnitude, eating smart can really make you smarter. Try to implement more of these readily available nutrients and see just how brainy you can be!
