There’s an adage that goes, “If you want to boil a live frog, don’t turn up the heat too quickly, or the frog will jump out of the pot.” Aside from why you would want to boil a frog, the point is that we may not notice incremental life-threatening changes until the damage is severe.
If that’s true, the lockdowns and shut-ins of the past two years may have boiled our collective well-being to shoe leather.
Beginning in 2022, The Epoch Times
reported widely on the devastating effects of the COVID-19 lockdowns. From increases in obesity and depression to delayed learning and cognitive development in children, the evidence (

As bad as the effects of the lockdowns were, the greatest harm to our health might well be the long-term increase in the time we spent—and continue to spend—indoors.
Starting in the 1980s, the amount of time Americans spend indoors has been steadily climbing. Even before the lockdowns,
data showed that Americans were spending a whopping 90 to 93 percent of their time indoors. That isn’t healthy.
Years before governmental COVID-19 mandates forced people indoors, a
mountain of evidence revealed a nasty slew of negative physical and psychological effects from too much time indoors: depression, cardiovascular disease, respiratory ailments, inflammation, and much more.
Although our health has clearly suffered from being “locked in,” there’s good news: A substantial body of evidence suggests that our bodies are hardwired to be cured by nature. Just 20 minutes a day spent outside
has been shown to improve health dramatically.
In the early 1980s, a Japanese researcher named Tomohide Akiyama began publishing findings about how our bodies responded to being in a natural environment. In a series of studies, Akiyama encouraged participants to go out into a forest or a park and slowly, mindfully, spend short periods of time there, a process he called
shinrin-yoku, or “forest bathing.” Akiyama found that being out in nature lowered blood pressure, improved heart function, and suppressed the release of stress hormones.

Why do our bodies respond so well when we spend time outside?
In 1984, American biologist Edward O. Wilson published a book called “
Biophilia,” in which he speculated that we are genetically designed to be attracted to nature and natural things. Wilson proposed that our bodies and minds adapted to living outside and thus don’t respond well to being kept indoors.
“The biophilia hypothesis boldly asserts the existence of a biologically based, inherent human need to affiliate with life and lifelike process,” he wrote.
Wilson’s biophilia hypothesis seemed to support Akiyama’s work, but nonetheless sparked a 20-year debate within the scientific community.

In 2005, journalist Richard Louv published “
Last Child in the Woods.” In the book, Louv coined the term “nature-deficit disorder” to describe what he believed was happening to children as the time they spent indoors increased.
Louv chronicled exploding rates of obesity, skyrocketing adolescent depression, and a whole host of negative effects brought on by “an increasing divide between the young and the natural world.”
Louv agreed with Wilson that we are genetically wired to be outside and wrote that our children were suffering from a gross deficiency of nature, which he called “Vitamin N.” The response to “Last Child in the Woods” was nothing short of sensational, and the book was praised by a chorus of leading thinkers, writers, clinicians, and politicians.
Biological Nature or Divinely Nurtured?
Centuries before we began gathering clinical data about the benefits of being outside, people knew that the natural world held the power to heal. From the ancient Greeks to the Romans to the native peoples of the Americas, there’s a long history of extolling the benefit of being in and around nature.While Akiyama, Wilson, and Louv theorized that this healing response is linked to evolutionary biology, others such as theologian and ecologist Christopher Thompson claim that we are drawn to nature because of our divine origins.

While Thompson doesn’t deny the physical benefits of being outside, he emphasizes that the driving force of these benefits is that nature, with its order, structure, and predictable rhythms, has been created as our first “classroom” in which we learn about the Creator and how we fit in the created order.
In his book “
The Joyful Mystery,” Thompson takes issue with the theory that we feel better when in nature because of a connection to a “biologically driven unconsciousness ... remnants of a past now long forgotten through the centuries of evolution and progress.”
Instead, Thompson asserts that the joy, even the wellness that we feel when in nature, comes from a deep connection with our metaphysical origins—an insight “into our status as a creature within the cosmos, created by God who is love.” Put plainly, Thompson writes that we feel better in nature because we feel a sense of awe, which is “a glimpse of the gift of being.”
Whether the benefits of being outside arise from our biology or a connection to a creator, the evidence of those benefits is clear and conclusive. These benefits are especially strong during the winter months, during which daylight hours are shorter and, as the temperature drops, we tend to spend increased time indoors.

According to some studies, during the cold winter months, we spend nearly twice as much time indoors as during summer. While this isn’t surprising, more time indoors increases our exposure to allergens—such as dust mites—known to cause respiratory difficulties such as asthma (
pdf), especially in children.
When we combine our increased time indoors with shorter winter days, we decrease our exposure to sunlight, which in turn reduces our levels of vitamin D, an essential for
fighting infections such as COVID-19. Taken together, the drop in sunlight during winter, increased exposure to allergens, and a lack of vitamin D take a toll on our
mental and physical health.
However, there is good news: Just 10 to 20 minutes spent outside during the winter months has been shown to improve physical and mental health,
according to a study published in Frontiers in Psychology in 2019. And the benefits of being outside aren’t connected to any particular activity—walking, building a snowman, or just standing outside can all help improve health during the winter months.
On colder days, when the temperature is below freezing, be sure to dress appropriately. Layers of clothing work best, and clothing made from natural fibers such as
wool and down tend to work better than synthetics. Cotton clothing will keep you warmer than polyester, but since it’s a natural fiber, it tends to absorb and hold moisture (from the weather or perspiration), and it’s a poor insulator when wet.
Dressing well and staying warm can make going outdoors in winter a pleasure rather than a chore and help ensure you actually want to get outside. As the old Scandinavian saying goes, “There is no bad weather, just bad clothing.”
