When we think about our day at work, what do we interact with? Most of us commute either by car, train or bus, then we're in the office all day. We may pop out for lunch or we've got some with us, so we eat it there. Then we get back to work and then back onto the commute and home. How many opportunities will we have to interact with anything 'natural' during that time?
Biophiliais a theory that says that we are living in a world that is growing increasingly extrinsic; it is cutting us off from reality and places us in one that isn't of benefit to us (at least health-wise). Being natural creatures ourselves, we are designed to live in an environment that is natural, so it isn't too much of a stretch to say that when we spend long periods of time outside of nature, we will experience negative feelings.
As a result of negativity infecting our being, our performance and even our mental and physical health will not be hitting the heights they should be doing. This is something that forward-thinking office design companies have recognised and why businesses should be placing biophilic design at the heart of their office refurbishment in London.
