Positive childhood experiences of blue spaces linked to better adult well-being

As a fan boy from the ‘great outdoors,’ I was thrilled by this information.

New research based on data from 18 countries concludes that adults with better mental health are more likely to report having spent time playing in and around coastal and inland waters, such as rivers and lakes (also known collectively as blue spaces) as children. The finding was replicated in each of the countries studied.

Mounting evidence shows that spending time in and around green spaces such as parks and woodlands in adulthood is associated with stress reduction and better mental health. However, we know far less about the benefits of blue spaces, or the role childhood contact has in these relationships in later life.

Love of nature is partially heritable, study of twins shows

A person’s appreciation of nature and their tendency to visit natural spaces are heritable characteristics, according to a large-scale study of UK twins led by Chia-chen Chang at the National University of Singapore, publishing in the open-access journal PLOS Biology.

Researchers surveyed 1153 pairs of twins on the TwinsUK registry about how they experience nature, asking them to rate their familiarity with and desire to be in nature, and how frequently they visit natural spaces such as public parks and private gardens.

They found that identical (monozygotic) twins, who share almost 100% of their genes, were more similar to each other in their orientation towards nature and how frequently they visited nature compared to fraternal (dizygotic) twins, who share around 50% of their genetic material. Heritability ranged from 46% for nature orientation to 34% for frequency of garden visits, suggesting a moderate influence of genetics over how people experience nature. However, environmental factors explained more than half of the differences between individuals. People living in urban environments tended to have less nature experiences, due to for example limited access to gardens, highlighting the importance of availability in shaping nature-seeking behaviors. Heritability also declined with age, suggesting that genetics may become less influential as people age and experience a unique set of environmental conditions. 

Spending time in natural spaces has been found to improve mental well-being, but different people experience and benefit from nature differently. This study provides the first evidence for a genetic component to both our predispositions towards nature and our tendency to visit natural spaces. Nature-oriented people may actively seek out nature even if it means traveling from their home, but diverse urban planning is needed to provide access to natural spaces – and the benefits they offer – for all, the authors say.

“Spending time in nature links to better health and wellbeing,” adds Chang. “A twin study shows that a person’s desire to be in nature and how often they experience it are influenced by both genes and personal experiences.”

Your doctor may prescribe spending more time in nature instead of drugs – AHA

Dr. Robert Zarr loves to write prescriptions that you don’t have to take to the pharmacy.

Instead, he sends patients outside to soak in the healing powers of nature, combining the benefits of exercise with the therapeutic effects of fresh air and green space, according to the American Heart Association News.

“Going back millions of years, we’ve evolved outdoors,” said Zarr, a pediatrician who recently relocated to Ottawa, Canada, from Washington, D.C. “Why should we exist indoors? We need to be outdoors. The health benefits of being in nature are obvious.”

The idea isn’t new. The 16th century Swiss physician Paracelsus declared that “the art of healing comes from nature, not from the physician.” In Japan, public health experts promote shinrin-yoku, or forest bathing, as a key to physical and psychological health.

The premise is backed up with science. A 2018 meta-analysis in the journal Environmental Research reviewed more than 140 studies and found exposure to green space was associated with wide-ranging health benefits, including lower blood pressure and cholesterol, and lower rates of diabetes, stroke, asthma, heart disease and overall death.

Regular dose of nature may improve mental health during COVID-19 pandemic

I have to confess that as much as I enjoy riding my bike everyday, the fact that I live on the Chicago Lakefront and have beautiful Lake Michigan is no small consideration. There are also trees and various wildlife available, too.

A study published in Ecological Applications suggests that nature around one’s home may help mitigate some of the negative mental health effects of the COVID-19 pandemic.

I shot this earlier in the week. You can see the Navy Pier ferris wheel in the background.

An online questionnaire survey completed by 3,000 adults in in Tokyo, Japan, quantified the link between five mental-health outcomes (depression, life satisfaction, subjective happiness, self-esteem, and loneliness) and two measures of nature experiences (frequency of green space use and green view through windows from home).

More frequent green space use and the existence of green window views from the home were associated with increased levels of self-esteem, life satisfaction, and subjective happiness, as well as decreased levels of depression and loneliness.

“Our results suggest that nearby nature can serve as a buffer in decreasing the adverse impacts of a very stressful event on humans,” said lead author Masashi Soga, PhD, of The University of Tokyo. “Protecting natural environments in urban areas is important not only for the conservation of biodiversity, but also for the protection of human health.”

Time Outside May Benefit Health – Study

According to a recent British study published in the journal Scientific Reports, spending at least two hours a week outside may be good for one’s health. Nearly 20,000 English people were asked how many hours they spent in natural environments like parks, forests, and beaches in the last seven days; whether they considered their health to be good or poor; and if they felt their well-being was high or low. Those reporting nature contact of at least two hours per week were significantly more likely to report ‘good’ health and ‘high’ well-being compared to those reporting zero. (No additional benefit was seen from spending over 3.5 to 5 hours in nature.)

While this association was seen even in people who did not meet current physical activity guidelines, the authors were unable to fully untangle time spent outside from time spent being active. It is possible that healthier, happier people are simply more likely to spend more time in nature or live in areas with more open space, but the association was seen even for those with long-term illness or disability. In this study, even people who needed to travel outside of their neighborhoods to reach a park or other natural area benefited from regularly spending time in nature.

As regular readers know, I am a nature lover. Here are a couple of my posts on being outside:

Urban green space boosts mental health – Study

For the record, I pretty much live in downtown Chicago. I am a city guy and love the fact that I have access to everything a great city has to offer. Within a mile of my apartment, I have dozens of restaurants of every kind, the Art Institute of Chicago, the Chicago Public Library for starters. In the evening, there is the Chicago Symphony, the Lyric Opera and tons of smaller, but very professional theater groups. Those are some of the high points of living in a major metropolitan area. Nonetheless, despite this uber-urban environment, my favorite aspects of where I live are Lake Michigan over which I get sunrises every morning, along this lakefront lie a bike path stretching for miles. In addition, there is also the wonderful nature scene along the shore where rabbits, squirrels, ducks, geese and other wild life flourish. I carry nuts and seeds on the bike when I ride so I can feed the sparrows, ducks and squirrels.

I truly believe I have the best of both worlds – an urban environment as well as the beauty of nature – here.

Enjoying the outdoors safely …

I have written time and again about the benefits of exercising and doing it outdoors. When I visit a a health club I feel like a prisoner. Of course, I live on the shores of Lake Michigan with the wonderful Chicago lakefront outside my door. So, in that regard, the outdoors is an integral part of my life. But, for those of you who are in town, or in the burbs, there is some preparation necessary to enjoy nature in a safe way.

If you’re heading for the great outdoors, be sure to bring along some common sense.

That’s the best way to reduce the chances that a bite, sting, cut, scrape, burn, blister, rash, sprain, strain, more serious injury or other mishap will spoil your outdoor adventure.

“Knowing your limits, not trying to do too much, knowing where you’re going and what you might encounter there and being aware of the environment you’re in are the best ways to avoid problems outdoors,” said Henderson McGinnis, M.D., an associate professor of emergency medicine at Wake Forest Baptist Medical Center, medical director of its AirCare emergency transport service, a recognized expert in wilderness medicine and an experienced outdoorsman.

I shot this on a recent bike ride.

“Doing a little preparation before you go and being sensible while you’re out there can make all the difference.”

That advice applies to veteran hikers, bikers, campers, climbers and paddlers, but it’s essential for people with no or limited outdoors experience. And there are lots of them these days.

That’s because Americans in general and children in particular simply don’t spend as much time outside as they once did. Consequently, overall familiarity with nature just ain’t what it used to be.

This byproduct of our high-tech, indoor-oriented society even has a name: nature-deficit disorder. Continue reading

Sounds of nature help us to relax – Study

I am a great believer in enjoying the outdoors. I ride my bike outdoors instead of opting for the exercise bike at the health club. Ditto, walking. I walk a lot outside rather than on the treadmill. So, I was very happy to run across this study from the Brighton and Sussex Medical School (BSMS).

The gentle burbling of a brook, or the sound of the wind in the trees can physically change our mind and bodily systems, helping us to relax. New research explains how, for the first time.

dscf6189

Researchers at BSMS found that playing ‘natural sounds’ affected the bodily systems that control the flight-or-fright and rest-digest autonomic nervous systems, with associated effects in the resting activity of the brain. While naturalistic sounds and ‘green’ environments have frequently been linked with promoting relaxation and well being, until now there has been no scientific consensus as to how these effects come about. The study has been published in Scientific Reports. Continue reading

The Best TV Show To Feel Joy, Amazement And Awe

This is so nice to learn, both on its own and in connection with nature itself for me. As I have written more than once one of my great pleasures riding my bike on the Chicago Lakefront is being out in nature.

Our Better Health

The study compared TV show genres to see which makes people happiest.

Watching nature documentaries — like being out in nature itself — can help you feel happier.

The survey of 7,500 people around the world found they felt happier after viewing clips from BBC nature documentaries.

The study compared watching the documentary to the news or a popular drama show.

People reported that after viewing the nature documentary they felt more:

  • joy,
  • amazement,
  • awe,
  • and curiosity.

At the same time it reduced feelings of anger, tiredness and stress.

Professor Dacher Keltner, who teamed up with the BBC for the study, said:

“I have long believed that nature and viewing sublime and beautiful nature in painting, film and video shifts how we look at the world, and humbles us, brings into focus our core goals, diminishes the petty voice of the self and strengthens our nervous system.
When the BBC…

More Exposure to Vegetation Linked with Lower Mortality in Women

I don’t know if that headline surprises you, but it doesn’t surprise me. As a daily bicycle rider, I get to enjoy the outdoors regularly and know that the setting benefits me as much as pedaling the bike.

Women in the U.S. who live in homes surrounded by more vegetation appear to have significantly lower mortality rates than those who live in areas with less vegetation, according to a new study from Harvard T.H. Chan School of Public Health and Brigham and Women’s Hospital. The study found that women who lived in the greenest surroundings had a 12% lower overall mortality rate than those living in homes in the least green areas.

nature-17941-18400-hd-wallpapers.jpg

The study suggests several mechanisms that might be at play in the link between greenness and mortality. Improved mental health, measured through lower levels of depression, was estimated to explain nearly 30% of the benefit from living around greater vegetation. Increased opportunities for social engagement, higher physical activity, and lower exposure to air pollution may also play an important role, the authors said.

The study was published online April 14, 2016 in the journal Environmental Health Perspectives. The paper is available here.

How to Exercise Safely in Hot Weather – NIH

With summer upon us it is important to play it safe when we play outside. Too much heat can be risky for healthy 40 year olds as well as seniors. The National Institutes of Health has issued the following tips for hot weather fun.

hot weather 3

Check the weather forecast. If it’s very hot or humid, exercise inside with a Go4Life DVD or walk in an air-conditioned building like a shopping mall.

Drink plenty of liquids. Water and fruit juices are good options. Avoid caffeine and alcohol. If your doctor has told you to limit liquids, ask what to do when it is very hot outside.

Wear light-colored, loose-fitting clothes in natural fabrics.

Dress in layers so you can remove clothing as your body warms up from activity.

Get medical help right away if you think someone might have a heat-related illness. Watch for these signs: Continue reading

A Super Relaxation Technique From Oleda Baker – Guest Post

Click anywhere to see these full size

Click anywhere to see these full size

As you can see from her photos, Senior Supermodel Oleda Baker is aging magnificently. I interviewed Oleda in December. She is a treasure trove of information on everything this blog stands for, namely weight control, healthy living and healthy aging, so I asked her if she would share some of her ideas with us. She has written 10 books on beauty and health. Her latest, written at the age of 75, Breaking the Age Barrier – Great Looks and Health at Every Age – was released in November 2010 and is available from Amazon or from her website www.oleda.com where she also sells her own line of health and beauty aids.

Your Body, Mind and Spirit Need a Break … here’s how: Years ago a doctor in New York City told me how he relieved his stress at the end of the day…. I never forgot it and have followed his advice most days.

When he went home, he drew a tub of very warm water and soaked in it for about twenty minutes. “When you get out of bed in the morning, your body’s organs are more or less rested,” he explained. “As the day goes on, those organs, as well as your mind and spirit get out of sorts due to the day’s stressful wear and tear, as it were. Hydrotherapy, a fifteen or twenty minute very warm bath, relaxes me better than anything else I’ve tried. I can feel myself returning to a calm state, and I believe it’s good for my long term health and well-being, too.”

I tried it not knowing if it would work for me…It did work! Ever since, I have soaked in a relaxing tub of warm water every day I possibly can. Until you try it it’s hard to believe how well it works. Here’s why:

Hydrotherapy – an Ancient Healing Practice

Hydrothermal therapy (hot water treatment) has been used as a traditional treatment for disease and injury by many cultures, including China and Japan. Asklepios, the ancient Greek god of healing, advocated the use of water as medicine. Similarly, Roman physicians, Galen and Celsus, used therapeutic baths for many remedies. So, water therapy has been used for centuries to heal the sick.

What is Nature-Deficit Disorder?

What are we talking about here? Wikipedia says Nature-Deficit Disorder refers to a hypothesis by Richard Louv in his 2005 book Last Child in the Woods that human beings, especially children, are spending less time outdoors resulting in a wide range of behavioral problems. This disorder is not recognized in any of the medical manuals for mental disorders.

I confess that on first blush this term sounded kind of tree-hugging and politically-correct to me. Don’t we have enough important things to concern us without worrying about being out in nature?

setwidth600-foto7002691
While this being nature deprived is usually applied to children, it doesn’t have to be. I am indebted to Kelly, The Spunky Caregiver, for introducing me to the concept in the first place.

Kelly mentioned it regarding care giving for seniors. She wrote, “Getting outside alleviates our stress and can literally change the mental state we are in. I have personally seen this in caring for seniors with moderate to advanced dementia. Having trees, gardens, horses and walking trails around, is like heaven after being inside. They begin to remember stories, smile more and connect. I have also seen it in rehab patients, how it inspires and elevates their optimism for recovery. For me personally, I need to get outside to feel alive in my body and the thought of being inside for days is painful. I love the sun and the trees and the air. Taking the seniors outside is a serious paid benefit!” Continue reading

A Doctor Visit in Flu Season

Having written about flu season for the past few months, when I started getting head cold symptoms last week and got nervous. In addition, an arctic freeze struck Chicago which has kept me off my bike. I found that working out in the health club, I was feeling really wiped out from a light workout. I actually napped afterwards. That and the head cold symptoms were enough for me. I booked a doctor visit. Mr. Conservative wasn’t taking any chances. I had gotten my flu shot early, but didn’t want to take any chances.  As I recommended to readers, I had gotten my flu shot early, but didn’t want to take any chances. You can read further on How to Fight the Flu elsewhere in the blog.

Here’s how bad the weather has been, “Chicago’s coldest blast of air in 2 years is easing—but slowly. By midnight Tuesday, the area moved into a 55th consecutive hour of sub-20-degree thermometer readings and 46 hours with wind chills below zero. Tuesday’s 11-degree high and 1-below morning low put the day into the record books as the city’s coldest of the past two years,” according to the blog of Tom Skilling, the awesome local meteorologist.

The walk to the doctor’s office over a mile was a bracing start to the day. Continue reading

Bike Riding in Snow’s No Fun

Chicago has just gone 307 consecutive days without a one inch snowfall. That is the longest such spell in 54 years. And, might I add, most welcome to me as a bicycle rider. Because of this snow drought, I have been able to ride many more times in these waning days of December than I would normally. As a result, I will post my biggest total mileage for a  year in my life in just three more days – over 8000 miles.

Looking west on Chicago's Riverwalk

The view looking west on Chicago’s Riverwalk with skyline in the distance

As you can see from the photos, the snow looked kind of pretty falling on the Riverwalk. However, look closely at the second photo taken on the next morning. Those patches of gray and white are ice patches and diabolical for a bicyclist.

The view looking east on the following morning

Looking east on the following morning

A sheet of ice is very simple to navigate, you just get off the bike and walk it till you are past the ice. But, sporadic ice patches are a totally different story. When I ride, I try to keep my heart rate in the target zone. For a septuagenarian like myself that requires a speed of around 12 miles an hour. Doesn’t sound very fast when you imagine yourself in your car inching along at 12 mph. On a bike, though, you are traveling at about 17 feet per second. And you aren’t strapped in to a cushy seat. You have a helmet and you are flying through the air riding a pair of skinny wheels. As the guy who has fallen at that speed and broken bones, I can attest that it is fast enough to get into trouble.
