Houseplants, Air Quality, and You

IrisesIt’s houseplant appreciation day! I did not know this, until fellow blogger This Veggie Life mentioned it (https://thisveggielife.blog/2018/01/10/houseplant-appreciation-day/). Evidently I am not the only one who loves to have plants around!

So take a moment to water your plants. Repot them if they are getting a little root bound – or buy yourself a new plant for your desk or your home. Here’s my confession – I am more of a light green thumb than a true green thumb. But, I’m working on it. My goal this year is to keep more plants alive than I let go through neglect or any of the many errors we all make with watering, light, and so on. Actually, I’d love to be able to pull of a jungalow style! (look it up on Pinterest – it’s a thing!)

I don’t know about you, but when I walk into a space full of lush green plants, I just feel like a breathe easier. Science says that we actually do breathe more easily when we have plants indoors.

A team of researchers in Portugal wanted to find out if this effect works for schools as well. After nine weeks of looking at the air quality of school rooms with six hanging potted plants compared to rooms without plants, as well as outdoor air. The rooms that contained plants had a higher indoor air quality – lower levels of volatile organic compounds (VOCs), lower levels of carbon dioxide, and even lower levels of particulate matter in the air! The research appeared in the Journal of Toxicology and Environmental Health in 2012 (https://www.ncbi.nlm.nih.gov/pubmed/23095155).

NASA has established that there are certain plants that do the best job of improving indoor air quality. Researchers there started looking at the question because if humans are going to live in space, we are probably going to be living in enclosed areas. The NASA teams wanted to know which plants would be most useful in that kind of environment. The answer is a list of plants that you can find easily, including golden pothos, English ivy, Peace lily, potted mums, and gerbera daisies. You can find the study results here:  https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19930073077.pdf On the whole, the plants improved the air in numerous ways, including removing benzene and formaldehyde from the air.

People are happier and more creative when they have plants in their workspace. I imagine this is true for children, too, although no study has been done to find out. One of the big challenges of course – as any indoor gardener knows – is keeping the plants alive and healthy looking. So, that is a little extra “work” but the pay off in terms of improved air quality and improved mood could be worth it!

Alright, so, I have a personal commitment to buy at least one new houseplant every other month. (On the in between months, I am focusing on lighting!) And I have to say that one of the sites that I am finding most inspiring this year about plants is http://www.succulentsandsunshine.com

ADHD is a walk in the park! Literally

“My child just can’t pay attention! We are trying everything! I’m at my wits end!”

I hear this often from my friends who have children with what the adults around them call attention issues. Although the trend towards instantly medication children with ADHD seems to be losing strength, I still know many parents who have been told – or believe – that their child has attention problems. And then they are placed on the roller coaster of trying the numerous strategies for coping with attention that are out there (many of which are effective, don’t get me wrong).

But I want to highlight the importance of getting all children out into nature. Every child benefits, but children with ADHD (diagnosed or not) seem to benefit more than most.

My personal view of this is that children need to run and play, and every single day should begin with recess, PE, or a walk in a natural setting, so that children can focus better. The research supports this, by the way – a 20-minute walk in a natural setting improves children’s attention and memory. And you can chalk that up to the natural setting – researchers found that a walk in an urban setting did not lead to as much improvement, according to research published in a 2009 issue of the Journal of Attention Disorders. Yes, that’s old research, but as long as children are not starting their day off with a 20 minute walk in nature, I think it’s worth talking about why. This doesn’t have to be “wasted” time, either. A nature walk is an excellent opportunity for hands on learning and social skills building. It’s important to remember that children feel a natural awe over things that we adults might not even pay attention to anymore. A huge sunflower, the patterns of bark, the tiniest inch worm – children have a depth of appreciation for the minutiae that benefits all of us.

Alright, so let’s say that taking a walk in a park isn’t feasible for the 4.4 million children who are thought to have attention deficit or hyperactivity disorders. There’s another way – green play areas. I am not talking about hard metal bars painted green! Kids who have the opportunity to play in a space that has a variety of greenery – shrubs, flowers, trees, grass – have milder attention deficit symptoms than their ADHD peers who are in less green play spaces. Perhaps not surprisingly, children with hyperactivity do best in wide open green spaces, according to researchers publishing in the November 2011 issue of Applied Psychology: Health and Well-Being. Again, old news, maybe – but take a journey around the schools in your area and you will probably not see the kinds of green play areas that would most benefit children.

At the very least, parents, let’s start making an effort to go walk in a park as often as possible with our kids. All this data applies to elementary school age children, by the way. We’ll explore the relationship between middle school and high school youth and green space at a later date.

Here’s what you can do –

  • If you have children, try to get them outside into parks as often as possible. Outside in general is good, of course, but the more diverse the greenery, animals, and birds, the better for them (and you!)
  • Advocate with your local schools, school board, or community for greener spaces – outdoor classrooms, school gardens, and so on. Of course, if you are committed enough to this to become a Master Gardener or a Master Naturalist, that’s even better! Volunteering is good for you too. But, it’s true that those green spaces require maintenance and even teachers sometimes need another trained adult to help them get the most out of green areas.
  • Create diverse green spaces in your neighborhoods and even indoors in your buildings. Make them inviting and friendly to children, as well as to parents.
