Study Finds Living Near Trees Comes With 6 Surprising Health Benefits

Study Finds Living Near Trees Comes With 6 Surprising Health Benefits

How healthy is it for you when you live near trees or there are a few outside your house or block, if you are lucky? Can trees really improve your physical and mental health? There are numerous studies which confirm that living near trees or forests is almost certainly the best medicine.

1. Living near trees helps you breathe better

Did you know that all the trees in the USA actually reduced air pollution by 17.4 million tonnes in just one year? They did this because the leaves absorb a lot of the air pollutants that can cause respiratory diseases in humans. Let’s plant more trees and protect the ones we have. The more trees the better!

“The best time to plant a tree was 20 years ago. The next best time is now.” – Chinese Proverb

The USDA Forest Services confirmed the health benefits by a doing a lot of interesting and much needed research on this. In spite of the fact that this cleaning up of the air took place in rural areas, the health benefits were felt over the whole nation. The USDA estimated that death from poor air quality was reduced by 850 and that cases of severe respiratory were reduced by 670,000.

India has decided to tackle their air pollution by planning to plant 2 billion trees along the nation’s highways. Not only will that help to improve the awful air quality and benefit the health of its citizens but will also give employment to 300,000 young people. Way to go.

2. Living near trees can save our lives

Let me tell you about a beetle which kills off ash trees. It is called the emerald ash borer whose larvae feed on the interior bark of the ash trees resulting in a blockage of vital water and nutrients which causes the trees’ death. Millions and millions of ash trees have been killed by this pest across an enormous number of US states. Dr. Geoffrey Donovan and his team from the Pacific Northwest Research Station showed that in the areas which had lost the most number of ash trees, there was a higher death rate from heart and respiratory illnesses.

 “Well my basic hypothesis was that trees improve people’s health. And if that’s true, then killing 100 million of them in 10 years should have an effect. So if we take away these 100 million trees, does the health of humans suffer? We found that it does.”- Geoffrey Donovan

 3. Living near trees will help you recover faster

If you have someone who is recovering from an illness or operation, try to make sure they get the room with a view of a tree, if there is one! Patients at a Pennsylvania hospital who were recovering from gall bladder operations recovered faster when their rooms had a view of trees than those who were just looking out at a building. The research by Dr. Roger Ulrich covered the years from 1972-1981. In general, it was found that those looking at the brick wall needed more painkillers, more encouragement and they usually took a day longer to recover than those who were lucky enough to have a room with a tree view.

 4. Living near trees can help with anxiety, stress and depression

Researchers at the University of Wisconsin decided to see if trees near people’s homes were having any beneficial effect on their mental health. They wanted to compare them with those living around more concrete. First, they surveyed the health of over 2,500 residents in Wisconsin and then gathered satellite images to show how many trees and vegetation were in their areas.

They found that those living near trees were suffering from less anxiety, stress and depression than those who lived in areas with a tree canopy of less than 10%. The interesting thing is that these results were consistent and were not affected by race, income level, or education. They noted that a poorer person living near a logging road was happier than wealthier residents on a treeless block in a town or city

The trees bend to caress me
The shade hugs my heart.” – Candy Polgar

5. Living near trees will help you fight obesity and diabetes

Researchers in Toronto found that the more trees on the block, the less likely people would end up being obese or have diabetes. They are also likely to live 7 years longer. All this data is correlational, researchers say but trees in the neighborhood can encourage people to go out and take more exercise. Just 10 extra trees on a city block can make a difference.

“Suburbia is where the developer bulldozes out the trees, then names the streets after them. – Bill Vaughn

6. Living near trees may help you sleep better

Many health experts are concerned that lack of sleep is leading to obesity, poor health and even divorce.  Prof. Diana Grigsby-Toussaint from the University of Illinois has led a  research study on trees and health. Data from 250,000 Americans was used. It was found that those who lived near green areas were sleeping better, especially if they were over 65 years of age.

“Across the entire sample, individuals reporting 21 to 29 days of insufficient sleep consistently had lower access to green space and natural amenities compared to those reporting less than one week.” – Prof. Grigsby-Toussaint

Did you know that when you plant a tree near your property or in your backyard, you are likely to increase its value by 15%? The benefits for the environment may not be quantifiable but they include reducing air pollution and cutting down energy bills by protection from cold winds in winter and increased shade in summer. You can enjoy many health benefits and give songbirds a home!

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!
