Frankly Freddie, THE MENTAL BENEFITS OF WALKING (Parenthetically Speaking)

Dear Humans,

I hate to say “I told you so”  but I told you so – Walking is good for you.  It’s my preferred form of exercise.  Peggy and judy have found lots of studies on the benefits of walking. They asked me to promote it since I’m an expert walker:

Walking (preferably with me)

  • Gives you a creative lift.  A study at Stanford showed a 60% increase in creative output. Researches called the kind of creativity “divergent thinking”, thinking out of the box, looking at many different possibilities. Walking lets out minds wander and this puts us in a good mental state for generating new ideas.  (My Human Judy is already a “divergent thinker” . . .  to a fault.  Her brain hasn’t ever been able to walk a straight line)

  • Boosts your mood. In one study scientists saw increased energy, good mood, attentiveness and confidence with 12 minutes of walking compared to 12 minutes of sitting.  (I like my human to be attentive and obedient)

  • Walking in nature also reduced repetitive negative thoughts (ruminating).

  • Improves memory.  (You’ll remember that walking helps you)

  • Just 10 minutes of walking may relieve anxiety and improve mood as well as a workout lasting 45 minutes. (I prefer long walks but I’m all for anything that gets my human in a better mood)

If it’s raining or snowing or blowing you can use a treadmill for a walking workout.

Walking on a treadmill gives you the most benefit if you vary the speed and incline so that your heart rate is raised and lowered. Sort of like walking up and down hills, going fast some times, slow some times. Setting a high incline makes you use more energy to walk, and you can get a good cardiovascular workout without as much strain on your knees (For those of us who have 4 knees that’s important)

Interval training is a way to get the most from a workout. So whether you are outside on a trail or inside on a treadmill here’s how to do intervals. Start with a warm up warm up 5 minutes, then do an incline  or speed for 3 minutes a few minutes, then back to level then 1 minute level at a walk, and repeat for about 20 minutes total.  (I do interval training with Judy – I run, stop, raise my leg, run some more, stop, sniff, saunter, stop, raise my leg, run, stop, sniff, trot . . .)

Another protocol I often follow, and you can too, is to go as hard as I can for 1 minute, then sniff and walk until I recover, then go again. 

Finding your target zone

My target zone is most often a tree or a post.  For humans it may be different and here’s how you do it:

Find an online calculator for your target heart rate zone, or use this:

For vigorous exercise, use 70 to 85 percent of your heart rate reserve or HHR

Here is Mayo Clinics formula:

  • “Subtract your age from 220 to get your maximum heart rate.
  • Calculate your resting heart rate by counting your heart beats per minute when you are at rest, such as first thing in the morning. (For the average adult It’s somewhere between 60 and 100 beats per minute.)
  • Calculate your heart rate reserve (HRR) – subtract your resting heart rate from your maximum heart rate.
  • Multiply your HRR by 0.7 (70 percent). Add your resting heart rate to this number.
  • Multiply your HRR by 0.85 (85 percent). Add your resting heart rate to this number.
  • These two numbers are your training zone heart rate for vigorous intensity exercise. Your heart rate during exercise should be between these two numbers.”

For example, I’m 6 dogs years old.

220-6= 114, my maximum HR
My  resting heart rate is resting
Then I subtract my resting heart rate from my maximum heart rate gives my heart rate reserve (HHR), (which is very confusing).

Multiply that by 0.7, then add my resting heart rate,

Multiply my heart rate reserve (HHR) by 85%  so 82×0.85=69.7 then add resting heart rate so 69.7+65=134.7 which is the high end of my target heart rate or training zone . . .

(I’ve computed my target zone to be 6 trees a minute.)

Frankly,

You can outsmart your brain – Neuroplasticity

Scientists used to think that the brain didn’t change after childhood. While it is true that our ability to learn new things is greater in our early years, it turns out our brains reorganize, physically change, and alter the function of different parts through our lives.

Each time we learn a new skill, make a new memory, rethink, respond, react, interact our brains change. Your brain is changing right now reading this post.

Why is this important?

Exercising and strengthening our brains is as important as keeping our bodies strong and limber.  The way you keep your brain in good shape spends on what you pay attention to, what you think, what you feel, and how you react to your environment.  You can change your brain with purpose by understanding how neuroplasticity works.

Two Main Ways You Can Drive Neuroplasticity

“Neurons that fire together, wire together.”*

Donald Hebb developed the idea that when two neurons fire at the same time repeatedly, chemical changes occur in both, so that they connect more strongly.  Because neuroplasticity follows this rule, it’s fundamentally reversible. Neurons that fire together wire together, but when neurons “fire apart” their connection becomes weaker. That means your brain works on a “use it or lose it” principle. Information and behaviors that you do not use weaken and may be completely lost. This is called called “synaptic pruning.

“It is almost just as easy to drive changes that can impair one’s memory or slow down one’s mental or physical control as it is to improve one’s memory or speed up the brain’s actions.”**

Brain change comes from external experiences

What we practice or are exposed to becomes part of our brain wiring.

Everything that happens in our life wires our brains.  What we repeatedly do becomes wired – everything from muscle patterns (remember when you first learned to walk, ride a bike?), to skills (learning a native language – when’s the last time you thought about how to form a sentence?) to smiling or frowning (do you have to concentrate on each of your facial muscles to express a feeling?).

To keep our brains growing, functioning well and avoiding decline, we need to give it challenges such as learning new skills, exploring new places, changing routines and interacting with people.

Brain change comes from internal experiences

Mental & emotional exercise changes our brains too. What we think and imagine can change our brains for the better or worse. Where we focus our attention directs the synaptic connections, the brains wiring, and develops and strengthens connections.

We can purposefully and actively create the connections we want. Thoughts and images we replay in our minds create stronger connections.  Make neuro-connections by thinking of things in sequence, create positive mental images, do crossword puzzles. (You already do this whenever you study for a test, read a book, rehearse what to say, worry about your future, ruminate on the past.)

Here are some proven ways to positively impact our brains:

 Mindfulness:

Practicing mindfulness is learning to control your thoughts and develop ability to focus where we choose.

Meditation:

By decreasing stress, anxiety and depression meditation helps encourage neurogenesis (development new brain cells). This can happen in just a few weeks.

Visualization: 

Neurons fire whether something is real or imagined. Imagining doing something is not very different from doing it in terms of  brain wiring. Athletes use this to “practice” by imagining a perfect performance over and over. It helps them actually perform better.  Research has validated that the practice influences physical changes from muscle strength to brain pathways.

Now that you’ve finished reading, give yourself a pat on the brain for all the new neuro-connections it has just made for you.

Scientists have figured out exactly how much you need to exercise to slow your heart’s aging process

There’s bad news good news and there’s bad news.

The Bad News:  “More than 610,000 people die of heart disease in the US each year—accounting for about 25% of total deaths, according to the US Centers for Disease Control and Prevention. Each year more than 735,000 Americans have a heart attack and 28% of those are a second heart attack.”

The Good News:  There are steps you can take to slow your heart’s aging process, increasing the chances of living a long, healthy life.

The Bad News: The trade-off is that you really do have to go to the gym.

“New research published in the Journal of Physiology pins down the number of days a week a person should exercise to maintain the overall health of their arteries, which stiffen with age and, as they do, increase the risk of heart disease and heart attack. Very few people experience heart attacks before age 45, and the average age is 65. But the new study suggests a way to keep your arteries physiologically “young.”

The study considered that every human has different-sized arteries, and found that the smaller arteries rely on fewer days of exercise per week than larger ones to maintain overall health.

The takeaway:

Medium-sized arteries need two to three days a week of 30-minute exercising to minimize artery stiffening. But to minimize the stiffening of equally important larger arteries, people should be exercising four to five days a week.

The study

“The scientists came to their findings by examining a group of 102 people—all of them older than 60—who had exercised over the course of their lives. The researchers started by measuring each person’s artery stiffness, then grouped them into four categories depending on how much they exercised through the years. One group was for people who generally exercised less that twice a week. Another was for “casual exercisers” who were active two to three times a week. The last two groups were for people who exercised four to five times and six to seven times per week.”

“A lifelong history of ‘casual exercise’ resulted in more youthful middle-sized arteries, which supply oxygenated blood to the head and neck,” the press release states. “However, people who exercised 4-5 times per week also had more youthful large central arteries, which provide blood to the chest and abdomen, in addition to healthier middle sized ones.”

This work showed exercise training over a long period of time can slow artery damage and the aging of the heart; the researchers say the next step is to study whether it can also reverse damage and aging of the cardiovascular system.

Did you know?: You are more Microbes, Fungi than HUMAN

“There are 10 times more cells from microorganisms like bacteria and fungi in and on our bodies than there are human cells. But these tiny compatriots are invisible to the naked eye.  . . . artist Ben Arthur gives a guided tour of the rich universe of the human microbiome.”

Fun to watch and informative!

YOUR body is host to 101 fungal species, with each person harboring between 9 and 23 strains. 

“A growing number of researchers feel that alongside bacteria, the fungi that inhabit our bodies – or, collectively, the “mycobiome” — may also be influential in both our well-being and, at times, disease.”

If your fungi are out of balance it’s not healthy.

“Even when we are alone, we are never alone. We exist in symbiosis — a wonderful term that refers to different organisms living together. Some animals are colonised by microbes while they are still unfertilised eggs; others pick up their first partners at the moment of birth. We then proceed through our lives in their presence. When we eat, so do they. When we travel, they come along. When we die, they consume us. Every one of us is a zoo in our own right — a colony enclosed within a single body. A multi-species collective. An entire world.”

Changes in our resident microbiota and their collective genome — called the microbiome — have been linked with a wide range of diseases, from various forms of arthritis to depression. At this point scientists tend to focus on which bacterial species might hinder or maintain health.

But our biota comprises a menagerie of microbes. And a growing number of researchers feel that alongside bacteria, the fungi that inhabit our bodies may also be influential in both our well-being and, at times, disease.

Fungi Out Of Balance

A Telltale Sign For Unwanted Fungi

  • French researchers distinguished the fungi present in healthy human lungs compared with those afflicted with cystic fibrosis. Aspergillus was most prevalent in the lungs of healthy people, whereas various Candida species dominated in those afflicted with CF and other lung disorders.
  • UCLA professor David Underhill  found that mammalian fungi interact with the immune system to control inflammation in the gut.
  • Mice in which the gene encoding for Dectin-1 was inactivated and in which colitis was induced came down with far more severe disease than mice with the active gene. With these findings in hand they then identified a Dectin-1 gene variant in humans that predicted a severe form of inflammatory bowel disease called ulcerative colitis.
  • Recent unpublished findings by Ghannom’s lab show that an interaction between fungi and bacteria in the gut aggravates the body’s autoimmune response in Crohn’s disease, another form of inflammatory bowel disease.
  • In collaboration with a group at Cleveland Clinic, Ghannoum also beginning to show that oral fungal populations are different in people with head and neck cancers.
  • Recent research found that autoimmune arthritis can be induced in mice injected with certain compounds found in fungal cell walls.

“None of these factors are working in isolation . . .it’s probably a confluence of them all interacting with each other and with us – what we eat, what kind of nutrients they have, genetic influences and how our immune system reacts to both fungi and bacteria in the gut.”

“We’re in a stage where we’re recognizing the biological significance of the fungi in our systems to help develop a common language and set of research approaches,” Underhill says. “Soon, hopefully, we’ll know how they can be good for us, bad for us and manipulated to our benefit.”

“There’s a certain beauty in our biologic cooperative; a reminder that mammalian life is complicated and communal, and that in nature imbalance has consequences. But perhaps tinkering with our fungal dwellers will one day help restore our biologic balance and fend off disease.”

How to trick your brain into thinking you are happy

Yes, you can “fake out” your own brain.

Smiling fools your brain into thinking you are happy, then this creates actual happiness.  A smile spurs a chemical reaction in the brain, releasing certain hormones including dopamine and serotonin*.

Now here’s the fake-out:  Our brain isn’t good at telling the difference between a smile because you are happy and a fake smile.

Smiles by Peggy

But wait . . . there’s more

A study performed by a group at the University of Cardiff in Wales found that people who could not frown due to botox injections were happier on average than those who could frown.”

“And there are plenty more studies out there:  Researchers at the University of Kansas published findings that smiling helps reduce the body’s response to stress and lower heart rate in tense situations; another study linked smiling to lower blood pressure, while yet another suggests that smiling leads to longevity.”

Smiling enhances our Immune system

“More than happiness is at stake.  Dr. Murray Grossan, an ENT-otolaryngologist looks at the study of how the brain is connected to the immune system. He asserts that it has been found “over and over again” that depression weakens your immune system, while happiness boosts your immune system.”

“What’s crazy is that just the physical act of smiling can make a difference in building your immunity,” says Dr. Grossan. “When you smile, the brain sees the muscle [activity] and assumes that humor is happening.”

Smiles are contagious

“This is because we have mirror neurons that fire when we see action,” says Dr. Eva Ritzo, As its name suggests, mirror neurons enable us to copy or reflect the behavior we observe in others and have been linked to the capacity for empathy.”

“Try smiling into the mirror. Dr. Ritzo recommends smiling at yourself in the mirror, an act she says not only triggers our mirror neurons, but can also help us calm down and re-center if we’re feeling low or anxious.”

So SMILE and pass on a dose of neurochemical happy

*Dopamine increases our feelings of happiness. Serotonin release is associated with reduced stress. Low levels of serotonin are associated with depression and aggression.  Low levels of dopamine are also associated with depression.

On the fly: Catch on to these Lessons and you’re Hooked for Life

Most people don’t realize I’m an outdoor person at heart.  I bike, hike, kayak and fish.  I just returned from fly fishing with my cousin Kate in the Catskill Mountains in southeast New York.  We had perfect weather and I was in my element with the tall green, green trees,  flowers in bloom, blue, blue lakes and country roads winding through low hills and picturesque towns.

Judy asked me what life lessons I learned form fly fishing.   I thought and thought but NOT while I was fly fishing. NO, never when, you are fly fishing which is the first lesson.

Life Lesson #1: Attention must be paid.  Pay attention to what you are doing.  Focus on the task at hand so you can do it well and improve your skills.  Know where you’re casting your efforts . . . You get the drift.

Fly Fishing:  To catch fish, I must pay close attention to what I’m doing:  Watch where to throw my line, watch if I’m getting a nibble.  Fly fishing requires lots of concentrated attention, similar to meditation . . . and life. 

Lesson #2. Be prepared. Have a plan for unwanted but foreseeable events.  If you fall in the water make sure it’s shallow but learn how to swim before you take the plunge.

Fly Fishing:  When wading in a moving river, it’s possible I could fall in.  My wading stick helps me avoid that, but I still keep a whistle to call for help,and have learned what to do (like positioning my feet downstream).

Lesson #3. Pack the essentials first.  You have a limited amount of resources.  First determine what is needed and then, if room, add what’s wanted.  Clutter weighs you down.

Fly Fishing: I pack the essentials first, then add the frills:  The most important is a net to catch the fish.  Since I want to carry just a FEW pounds of equipment, I’m careful about what I put in my vest pockets. In one pocket I have what I need to change flies (in case the fish don’t find the fly I’m using tasty, or replace a fly when I invariably lose them to an aggressive bush, grabby tree, deep rock or floating log). Another pocket holds nippers to undo messy tangles of line (especially those that wrap around my body).

If there’s room, I add things that are not essential but handy – extra flies, line, goo that help a fly float, gadgets to help flies sink, and indicators that help me know when a fish has taken my fly.

Lesson #4. Have a big netBe ready to capture the good things that come your way.

Fly Fishing:  Most of the time I catch small fish but I’m ready for the biggest fish.   I carry a BIG net because I can put a small fish in a big net, but can’t put a big fish in a small net.   When I “land” my catch I look to make sure it’s a fish before cradling it back into the water to join his other fishy friends.  

Lesson #5.  Water-proof yourself.   When you do fall down most of you will stay dry . . . otherwise you’ll get moldy.

Fly Fishing:  I dress for success. That means waterproof clothing and boots, so I can stand in a stream trying not to fall in.   But nice accessories are important, such as a cute vest with all the flys, and my wading stick  (form and fashion all in one).

Lesson #6.  Keep Casting.  It takes a LOT of practice to know where and how to make a catch.

Fly Fshing  I practiced casting first and a lot (because I couldn’t  practice landing a fish until I caught one). Practice means noticing where my fly lands (in the water is definitely desirable), and learning were it is likely there’s a fish waiting.  Practice means reading the currents and . . . improving my aim

Lesson #7. Tie down what’s important.  When you find yourself in the wilderness you don’t want to “lose it” downstream.

Fly Fishing:  I keep what I value close by and tied down.  Standing in a moving stream and dropping something I need  (like my fishing rod) means it’s GONE. Finding a way to attach important stuff -like my “nippers” that are on a “zinger”  (a retractible string with a pin on the end) is what makes a good fly fisher person . . .  which brings me back to Lesson #6.

   . . . Kate and I caught a 6 fish and released them to swim free.

Forest Bathing: Shinrin-yoku Can boost Immunity, reduce stress & elevate your mood

You don’t need to take off your clothes or use soap or water for that matter. Forest bathing isn’t a bath – it’s a sensory immersion. Forest bathing isn’t a hike, it’s a meander.

Taking a Forrest Dip by Peggy

The idea is to go slow and let yourself take in nature – the sights, smells and sounds of the forest – notice things you might ordinarily miss.  It’s a meditation which helps clear your brain, and see your surroundings with fresh eyes. 

The practice began in Japan. Back in the early 1990s the Japanese Ministry of Agriculture, Forestry and Fisheries coined the term Shinrin-yoku — which translates roughly as forest bathing.

“There’s a growing body of evidence that the practice can help boost immunity and mood and help reduce stress. “Medical researchers in Japan have studied forest bathing and have demonstrated several benefits to our health,” says Philip Barr, a physician who specializes in integrative medicine at Duke University.”

One study published in 2011 compared the effects of walking in the city to taking a forest walk. Both activities required the same amount of physical activity, but researchers found that the forest environment led to more significant reductions in blood pressure and certain stress hormones.

“Researchers were able to document a decrease in blood pressure among forest bathers. As people begin to relax, parasympathetic nerve activity increases — which can lead to a drop in blood pressure.”

“On average, the forest walkers — who ranged in age from 36 to 77 — saw a reduction in their systolic blood pressure from 141 mmHg down to 134 mmHg after four hours in the forest.  This might not sound like a big difference, but it can be clinically significant. Most doctors these days agree that people younger than 60 should aim to keep their blood pressure under 140.”

“There’s another factor that might help explain the decline in blood pressure: Trees release compounds into the forest air that some researchers think could be beneficial for people. Some of the compounds are very distinctive, such as the scent of cedar.”

  • “Back in 2009, Japanese scientists published a small study that found inhaling these tree-derived compounds — known as phytoncides — reduced concentrations of stress hormones in men and women and enhanced the activity of white-blood cells known as natural killer cells .”
  • “Another study found inhalation of cedar wood oils led to a small reduction in blood pressure. These are preliminary studies, but scientists speculate that the exposure to these tree compounds might enhance the other benefits of the forest.”

“The idea that spending time in nature is good for our health is not new. Most of human evolutionary history was spent in environments that lack buildings and walls. Our bodies have adapted to living in the natural world.”
