The mental and physical health benefits of ecotherapy

There are countless studies that prove ecotherapy (often referred to as nature therapy) is beneficial for your physical and mental health.

  • What was once considered a simple practice and ideology about the benefits of nature has been proven in multiple studies to positively impact our physical and mental health.
  • Some of the benefits of spending time in nature can be: a boost in killer-cells that fight off viruses, an ability to maintain focus and improvement in mental health conditions such as anxiety, depression and other mood disorders.
  • To explain the all-encompassing benefits of nature, the Japanese have coined the term "shinrin yoku", which translates to "forest bathing."

Ecotherapy (also referred to as nature therapy) has been proven to be effective and is used in various practices and cultures around the world—and yet, it is still one of the most under-appreciated forms of therapy.

For a period of time, nature therapy was considered a simple practice for those who believe that we are connected to and impacted by the natural environments around us. However, there is now more research to support this ideology.

How nature therapy works to better your physical and mental health

The benefits of nature have been studied for decades. In fact, in 1982, the Japanese Ministry of Agriculture, Forestry, and Fisheries coined the term "shinrin yoku", which means "forest bathing."

Nature increases activity in natural killer cells that fight off viruses.

While we stroll around the forest, breathing in the fresh air, airborne chemicals like phytoncides (a chemical many plants give off to fight disease) are also entering our system. When this happens, the human body responds by increasing the number of natural killer blood cells (a type of white blood cell) which attack virus-infected cells.

In one 2009 study, participants spent 3 days/2 nights in a forested area. Their blood and urine were sampled before, during, and after the trip. Natural killer cell activity measured significantly higher during the days spent in the forest and the effect lasted up to 30 days after the trip.

This suggests that a few days in nature every month could potentially allow your natural killer cell activity to maintain at a higher functioning level, protecting you better.

Spending time in nature has numerous mental health benefits.

This groundbreaking research analysis of 10 UK studies involving over 1200 participants considered all the ways time in nature (known as green exercise) can improve a person's mental health and wellbeing.

The results of this analysis proved that both men and women have similar self-esteem improvements after experiencing time spent in nature, and the boost in mood particularly impacted men. The analysis showed the greatest improvements in mental health with the participants who were struggling with a mental health condition such as depression or anxiety.

A more recent study looked at the relationship between psychological responses and forest environments. Using the Profile of Mood States questionnaire, this research found that time spent in nature significantly decreased the scores for anxiety, depression, anger, confusion, and fatigue.

A walk in nature is more beneficial than a walk in the city.

Results of a 2008 study compared the restorative effects of natural versus urban environments, with natural environments proving vastly more beneficial. Nature, which is filled with intriguing stimuli, is able to modestly grab your attention in a way that requires no effort or additional actions. Urban areas can be filled with stimulation that captures your attention and requires additional directed actions (for example, stopping at a crosswalk).

This is why a walk in nature is much more beneficial for our minds than a walk in an urban setting—our minds are able to "switch off," giving time for restorative rest.

Nature related activities may be of use in future ADHD therapies.

Directed Attention Fatigue (DAF) is something you may be struggling with without even realizing it. It's a very common neuro-psychological phenomenon that results in the overuse of the brain's attention mechanisms. These mechanisms typically work for us to help us cope with distraction while maintaining on a specific task, but when we overuse that function, it becomes weaker and our ability to focus on task lessens.

Along with that, the part of the brain affected by attention fatigue (the right frontal cortex) is also involved in Attention-Deficit/Hyperactivity Disorder (ADHD). This study shows that children diagnosed with ADHD who spent time in natural outdoor environments show a reduction in ADHD symptoms. This is promising for the field of ADHD research, as nature therapy could potentially be used as part of an all-encompassing treatment plan.

Various therapies have been incorporating nature-related benefits for years, including:

While research continues on the benefits of nature, one thing has been made clear through decades of study and practice: Nature is good for your health, likely in more ways than we can even imagine.

This is what aliens would 'hear' if they flew by Earth

Surprising Science
  • There is no sound in space, but if there was, this is what it might sound like passing by Earth.
  • A spacecraft bound for Mercury recorded data while swinging around our planet, and that data was converted into sound.
  • Yes, in space no one can hear you scream, but this is still some chill stuff.

First off, let's be clear what we mean by "hear" here. (Here, here!)

Sound, as we know it, requires air. What our ears capture is actually oscillating waves of fluctuating air pressure. Cilia, fibers in our ears, respond to these fluctuations by firing off corresponding clusters of tones at different pitches to our brains. This is what we perceive as sound.

All of which is to say, sound requires air, and space is notoriously void of that. So, in terms of human-perceivable sound, it's silent out there. Nonetheless, there can be cyclical events in space — such as oscillating values in streams of captured data — that can be mapped to pitches, and thus made audible.

BepiColombo

The European Space Agency's BepiColombo spacecraft took off from Kourou, French Guyana on October 20, 2019, on its way to Mercury. To reduce its speed for the proper trajectory to Mercury, BepiColombo executed a "gravity-assist flyby," slinging itself around the Earth before leaving home. Over the course of its 34-minute flyby, its two data recorders captured five data sets that Italy's National Institute for Astrophysics (INAF) enhanced and converted into sound waves.

Into and out of Earth's shadow

In April, BepiColombo began its closest approach to Earth, ranging from 256,393 kilometers (159,315 miles) to 129,488 kilometers (80,460 miles) away. The audio above starts as BepiColombo begins to sneak into the Earth's shadow facing away from the sun.

The data was captured by BepiColombo's Italian Spring Accelerometer (ISA) instrument. Says Carmelo Magnafico of the ISA team, "When the spacecraft enters the shadow and the force of the Sun disappears, we can hear a slight vibration. The solar panels, previously flexed by the Sun, then find a new balance. Upon exiting the shadow, we can hear the effect again."

In addition to making for some cool sounds, the phenomenon allowed the ISA team to confirm just how sensitive their instrument is. "This is an extraordinary situation," says Carmelo. "Since we started the cruise, we have only been in direct sunshine, so we did not have the possibility to check effectively whether our instrument is measuring the variations of the force of the sunlight."

When the craft arrives at Mercury, the ISA will be tasked with studying the planets gravity.

Magentosphere melody

The second clip is derived from data captured by BepiColombo's MPO-MAG magnetometer, AKA MERMAG, as the craft traveled through Earth's magnetosphere, the area surrounding the planet that's determined by the its magnetic field.

BepiColombo eventually entered the hellish mangentosheath, the region battered by cosmic plasma from the sun before the craft passed into the relatively peaceful magentopause that marks the transition between the magnetosphere and Earth's own magnetic field.

MERMAG will map Mercury's magnetosphere, as well as the magnetic state of the planet's interior. As a secondary objective, it will assess the interaction of the solar wind, Mercury's magnetic field, and the planet, analyzing the dynamics of the magnetosphere and its interaction with Mercury.

Recording session over, BepiColombo is now slipping through space silently with its arrival at Mercury planned for 2025.

Learn the Netflix model of high-performing teams

Erin Meyer explains the keeper test and how it can make or break a team.

  • There are numerous strategies for building and maintaining a high-performing team, but unfortunately they are not plug-and-play. What works for some companies will not necessarily work for others. Erin Meyer, co-author of No Rules Rules: Netflix and the Culture of Reinvention, shares one alternative employed by one of the largest tech and media services companies in the world.
  • Instead of the 'Rank and Yank' method once used by GE, Meyer explains how Netflix managers use the 'keeper test' to determine if employees are crucial pieces of the larger team and are worth fighting to keep.
  • "An individual performance problem is a systemic problem that impacts the entire team," she says. This is a valuable lesson that could determine whether the team fails or whether an organization advances to the next level.
