September is that time of year. One of my favourite times of year to run. You’re probably expecting me to reel off a load of scientific reasons why early autumnal running is beneficial. Aside from the cooler conditions, I can’t think of any other reason. The non-scientific reason why I like running this time of year is because of the fact that if I run in the evening, it’s not dark enough for people to close their curtains, but it’s dark enough inside for them to put their lights on, meaning, I can have a good old nose in as I run past. Romantically, I enjoy it so I can imagine what it would be like to live there, or see how cosy it is while I’m out pounding the pavement, but recently I have been remarking to myself how the people inside are interracting with oneanother, or not, as the case seems to be. The first thing that strikes me is the size of the TV screens, especially when compared to the size of the room. The usual scene tends to be: huge, oversized TV at one end of the room and at the other end, as far away as physically possible in a ten foot square room, the family and pets, wide eyed. The other scene is a family of two, three or four, oversized TV blaring away, yet all concerned are all being swallowed whole by their smart devices, their thumbs scrolling up and down in a motion that Fran Healy of the Scottish rock band Travis, described as ‘stroking the hamster’.
It’s one thing I didn’t have when I was a kid – the whole world at my fingertips, all the time. We never had a computer, no internet either. WiFi to the majority now is comparable to me finding a lawn big enough to play football on when I was younger.
The damage all of this does to our health is multifaceted. Firstly, there is the high level of inactivity that comes with vegetating in front of a screen, although this is not the case always. Bolt on food consumed while doing so, and that leads to the second issue. Depression, heart disease, diabetes to name three. Thirdly, and not widely documented, is the damage caused by blue light.
Blue light is a natural occurrence, being one of the colours emitted from the sun and carries more energy than, say, red, orange and green. It is everywhere, most notably in the screens of televisions, mobile devices and computers, which emit huge volumes of the stuff. Compared to the blue light emitted by the sun, they give off next to nothing, but the proximity of the blue light next to our faces, and the time spent in this way leaves us open to eye diseases, many doctors think. Blue light penetrates all the way through to the retina and can damage the light sensitive cells. The changes this causes are similar to macular degeneration, which leads to sight loss. More research is needed on the subject, especially surrounding just how much blue light exposure is too much. It is worth pointing out however, that not all blue light is bad for you. Some exposure to it can reduce symptoms in people who suffer from SAD (Seasonal Affective Disorder).
Blue light exposure, along with the other health conditions brought on by sedentary lifestyles can probably be considered a modern problem. It is my opinion that a continuation of it can undoubtedly lead to social problems. I think society as a whole is becoming less sociable and more insular. I see it every morning on my work commute. Heads down, looking at phone. People having conversations get glared at and tutted at. I’m a sociable guy, but I find nobody really wants to talk. I too get sucked into my phone, and ironically you’re reading this on yours, but I do belong outdoors.
It’s not right to preach, only to educate and guide people, which is kind of the mantra of this blog and my message to as many people as possible, just saying, we have one life, let’s live it as long as we can, as fully as we can, as healthily as we can, and share our experiences.
