Lighting, whether natural or artificial, affects all life on our planet. In humans, it plays a crucial role in regulating our circadian rhythm, the natural biorhythms of our body clock, and on the production of hormones in the body. It is proven that having enough light during the day, particularly during the winter, has a beneficial effect on mood and general quality of life. But lack of light in Sweden during the winter months means that many children do not play outside for long during the day. In fact, people living in the far north suffer from a higher incidence of ‘winter blues’. Mood-related issues and lack of energy typically start in autumn and can last well into the spring. By installing Philips CityTouch, connected LED-lighting at Tegnérparken, it was observed that children in the area are now able to play outside no matter how early it gets dark.
Commenting on the results Dr Louise Hallin, Child Psychotherapist said: “Even though this data is from a small group of children the results are impressive. Children spent less time on their computers and in front of their TVs, which is always great news. Anything that can lift them from that cycle of coming home and switching on must be praised. And playing outside for almost half an hour longer than normal, and using screens for an hour less a week, are highly significant figures.”
The ‘Light up the dark’ experiment initiated by Philips was conducted together with consulting firm Bjerking and the municipality of Uppsala, to explore whether increased opportunities for outdoor play would affect young children. The lighting is now a permanent fixture of the playground.
“Uppsala is part of a global city regeneration, the sort of thing that governments and businesses can do. We all need a nudge in the right direction sometimes, to encourage us to change our way of living and make us realize that perhaps we have let things stray for too long,” continues Dr Hallin. “Also, something else emerged that I hadn’t anticipated – almost 40 per cent of parents said that they played outside with their children. This is fantastic. Playtime with adults. We don’t see enough of that and for children to bond even more deeply with their parents in such a way is so important.”
Eva Barrett Global Head of Brand Communications for Philips noted “At Philips we believe we can always make life better and through a series of living laboratory experiments we will provide innovation solutions and ideas to particular challenges in order to improve people’s lives around the globe. Our lighting experiment in Sweden is the first of many experiments that bring us closer to achieving our vision of improving the lives of three billion people a year by 2025.”
Tegnérparken has been lit up using the latest innovations in energy efficient LED-lighting which creates good quality light that makes the park bright, vibrant and more alive. The children in the local kindergarten class were intimately involved in the installation and actually chose the color palette for the light bulbs throughout the park.
Key findings of the experiment on local kindergarten children are:
- Prior to the installation of the lighting in the park the children spent an average of 72 minutes a day playing outside. In the week following the installation, this rose to an average of 99 minutes of outdoor play time a day. This represents a 37% increase in time spent outdoors each day once the park had been lit.
- During the same period, time spent playing inside with electronic games or watching television dropped from an average of 72 mins a day to 61 mins a day. This 15% reduction represents approximately one hour less per week spent in front of a television or playing electronic games.
- 86% of parents surveyed reported that their children generally spend less time outdoors playing in winter time.
- During the week following the installation, 38% of parents played in the outdoors each day with their child/children.
- 57% of parents report seeing a noticeable improvement in their child’s mood when they play outside. They report the child being ‘more content’. 28% of parents report their child as having a better appetite after outdoor play. 43% report a positive impact on sleeping patterns.
Philips has developed a report outlining the findings of the experiment. Additional information including videos and commentary is available at www.livingexperiments.philips.com, #lightupthedark.
