A report from the BBC http://news.bbc.co.uk/1/hi/england/tyne/7932108.stm , suggests that ‘teenagers are biologically predisposed to go to bed later and wake later’, and that they are underperforming at school as a result. The proposal is to start the school day later, and put challenging classes later in the day, when teenagers perform better.
Whilst I applaud some of the recommendations, and the acknowledgement of our individual biorhythms (internal body clocks) as an influence on our function, I think the study does not consider the one major influence that drives our internal body clocks – the sun.
Circadian (the time of the day) rhythm’s main influence is that of light, and it influences all other rhythms and functions within our bodies, for example, sleep/wake, body temperature, thirst, and appetite. The problem is that our bodies can’t distinguish between sun light and light from TV, light bulbs, computers, mobile phones, which not only can reset our circadian rhythm, but cause a stress response that will hinder our quality of sleep and our ability to regenerate and repair all the cells of our body, including brain cells.
Most teenagers make use of all of these devices and often use or watch them in bed, which will have a profound influence, on their ability to function the next morning. I think that we need to look back to nature for an answer and educate teenagers about some foundations of human life – sleep, and diet. Making this part of the educational syllabus will not only help teenagers sleep and perform better at school, but help build a better relationship with nature.
At present I believe we show great disonance with nature whilst we exploit its resources. Oil has given us a false sense of security,but this will soon run out, and I believe the future will be governed by our ability to change and work with nature. We need to be teach children in school that we are part of nature and inextricably linked with the soils, the sun, the moon, the rain forests, the poles. With this information, I believe we will again become resonant with the rest of nature and our overall health will improve, including our teenagers!
