Nature-deficit disorder: What kids lose by not experiencing the outdoors enough
Research explains the positive impact and health benefits of children spending more time in nature.
- "Nature-deficit disorder" is the term coined by author Richard Louv, to help put a name to the ever-growing problems associated with children spending less time in nature.
- Research has provided evidence that prove Richard Louv's theories on the importance of nature to the human body and mind. This research proves a link between time spent in nature and improvements in areas such as motivation, problem-solving and self-esteem.
- There are many simple, actionable ways parents and educators of young children can incorporate nature back into the lives of children both in school and at home, such as starting outdoor playgroups or reintegrating nature into the school curriculum.
"Passion is lifted from the earth itself by the muddy hands of the young; it travels along grass-stained sleeves to the heart." - Richard Louv, Last Child in the Woods
The term "Nature-Deficit Disorder" was coined by Richard Louv, not to serve as a medical diagnosis, but to give meaning to a significant problem in modern society - the human costs of alienating ourselves from nature. There is an ever-growing gap between human beings and nature due to open green space being urbanized and large advancements in technology.
Since the term was coined in Louv's 2005 publication "Last Child in the Woods: Saving Our Children from Nature-Deficit Disorder", it has been used as a rallying point for a movement called the New Nature Movement that strives to reconnect children to nature and educate people on the health benefits nature can have on the human mind and body.
What do our children lose by not experiencing enough nature?
Multiple research studies have proven the positive impacts time spent in nature has on the growing mind and body.
Many intriguing studies on this topic provide profound insight into what children are missing by not experiencing enough nature.
To summarize, a lack of vitamin D, increased symptoms of mental health conditions such as ADHD and a lack of motivation among children who spend less time in nature are among the key concerns of researchers who support Richard Louv's theory.
An important 2008 study by Susanna Huh and Catherine Gordon has suggested a strong link between the decline in outdoor activities and the dramatic rise in vitamin D deficiency. Vitamin D, which our bodies produce as a response to sun exposure, is essential for maintaining healthy bones and teeth and can also protect against diseases such as type 1 diabetes.
According to Louv: "Time in nature is not leisure time; it's an essential investment in our children's health (and also, by the way, in our own)."
Researchers have gathered evidence that proves exposure to nature is important to the physical and mental health of children
The American Institutes for Research (AIR) conducted another study in 2005 that focused on 255 sixth-grade students from elementary schools across California. These students attended three outdoor education programs between the months of September and November.
The study evaluated the children across eight different constructs: self-esteem, cooperation, conflict resolution, leadership, relationship with peers, problem-solving ability, motivation to learn and overall behavior in class.
The children were split into two camps: One group of students did the outdoor schooling sessions first, and the other group was used as a baseline and would do the same outdoor schooling sessions after the first program had finished.
Ten weeks after the first study concluded, the positive change in the children was very obviously noted in the post-experiment surveys, with the children who attended the outdoor schooling sessions first showing large improvements in the area of conflict resolution.
The remaining group of children who had not yet completed the outdoor schooling sessions scored significantly lower across 7 of the 8 constructs that were being measured.
The teachers of the children were also asked to submit surveys (separate from the surveys done by the researchers) about the children before and after the experiment. According to the before and after remarks of the teachers, the children who attended outdoor schooling in the first camp showed significant positive gains in the areas of self-esteem, problem-solving, motivation to learn, and behavior in class.
Along with these findings, it was also discovered that the students who attended the outdoor training sessions raised their grades in the science department by up to 27% (according to the pre-survey and post-survey answers). This increase in grades was maintained for up to 10 weeks following the program.
Another study, this time conducted in northeastern China in 2013, further supports the importance of nature in children's lives. This time, the study focused on the association between green-spaces that surrounded schools and the mental health condition of attention-deficit/hyperactivity disorder (ADHD).
Data for this particular study came from measuring the green spaces around the schools and two reports given at different times from the parents regarding potential ADHD symptoms in their children.
This data was collected over a span of 10 months and showed results from seven different cities. The study included almost 60,000 children between the ages of 2 and 17, from 94 schools around the country.
The results of this study showed that the levels of green-ness were linked to the incidence of ADHD behavior/symptoms in the children. Greater greenness levels around the school were significantly linked with lower odds of ADHD symptoms present in the children of that school.
How parents (and educators) can easily and affordably reconnect children with nature
There are many easy and affordable ways you can incorporate nature back into your child's life.
The urbanization of society and advances in technology (among other things) have made nature less accessible to our children. However, Richard Louv (and the researchers who have supported his theories) aren't just proving there is a problem - they are also providing communities ways to leap into action.
Parents who are looking for actionable ways to involve nature in their children's lives can do more than just let their children play outside an hour extra a day. Parents can push to become more involved in movements that place importance on nature-learning for kids, such as the Leave No Child Inside movement that has sprung up all over the United States and Canada.
Simple things such as starting an outdoor club with other parents who are interested in maintaining the connection between human beings and nature can be extremely beneficial. In Omaha, for example, a parent-lead association was created by 5 families that offer hands-on, nature-based play activities for children.
If you're an educator, one of the best things you can do to stop the ever-growing gap between our children and nature is to educate yourselves on the cognitive (and other) health benefits of allowing children to have more interactions in nature. Then share that knowledge with not just your students, but other educators as well.The Children & Nature Network site is one of the best resources for re-integrating nature back into the lives of our children, offering links to many different research papers that give you information on the benefits of unstructured outdoor play to whole curriculums that can be based on outdoor learning.

Next to it is the plica semilunairs, and it's what's left of a third eyelid that used to — ready for this? — blink horizontally. It's supposed to have offered protection for our eyes, and some birds, reptiles, and fish have such a thing.</p>

Palmaris longus muscle. Image source: Wikimedia commons<p> We don't have much need these days, at least most of us, to navigate from tree branch to tree branch. Still, about 86 percent of us still have the wrist muscle that used to help us do it. To see if you have it, place the back of you hand on a flat surface and touch your thumb to your pinkie. If you have a muscle that becomes visible in your wrist, that's the palmaris longus. If you don't, consider yourself more evolved (just joking).</p>

Goosebumps. Photo credit: Tyler Olson via Shutterstock<p>It's not entirely clear what purpose made goosebumps worth retaining evolutionarily, but there are two circumstances in which they appear: fear and cold. For fear, they may have been a way of making body hair stand up so we'd appear larger to predators, much the way a cat's tail puffs up — numerous creatures exaggerate their size when threatened. In the cold, they may have trapped additional heat for warmth.</p>

Palmar reflex activated! Photo credit: Raul Luna on Flickr<p> You've probably seen how non-human primate babies grab onto their parents' hands to be carried around. We used to do this, too. So still, if you touch your finger to a baby's palm, or if you touch the sole of their foot, the palmar grasp reflex will cause the hand or foot to try and close around your finger.</p>
