Teenagers and sleep - Family Lives Understanding your teen's body clock "My son David almost missed one of his GCSE’s this summer because he just can't get out of bed in the mornings," says 38 year old Ellen, from Huddersfield. "I have to leave the house at 7.30 and then I'm worrying the whole time, phoning him every 10 minutes to try and make sure he gets up on time for school. How hormones affect the teenage body clock Teenagers and their parents have very different body clocks. When it comes to sleep patterns, there are definite changes in teenagers - particularly around the timing of sleep, explains Neil Stanley, a sleep researcher at the University of East Anglia. Scientist David Bainbridge, author of "Teenagers: A Natural History" believes this is due to a 'rewiring' of the brain in adolescence which may mean that the teenage body clock runs more slowly than an adult's, making the day seem longer. David also says that teenagers haven't yet developed the mechanism required for registering fatigue.
Secrets of the teenage brain Several years ago Frances E Jensen’s 16-year-old son wrote off a car. A few years earlier, her other son had returned from a friend’s house with his hair dyed jet black. The University of Pennsylvania neurologist was finding her teenagers’ erratic behaviour increasingly taxing, so she decided to study teenage thought processes and gathered her research in the book The Teenage Brain. But does knowing what is going on in a teenager’s brain make them any easier to live with? Given that the relationship between parents and teenagers is one of the most fraught in family life, we asked readers to send in questions for Jensen to tackle. Clothes left in the bathroom, losing things, plates festering under the bed… Why doesn’t my teenager care about being tidy? Why does my daughter always seem so angry, especially with me? I feel increasingly cut out from my teenager’s life. Why won’t my teenager go to bed, and why can’t I get them up in the morning? My child loves playing video games.

Why Procrastinators Procrastinate PDF: We made a fancy PDF of this post for printing and offline viewing. Buy it here. (Or see a preview.) pro-cras-ti-na-tion |prəˌkrastəˈnāSHən, prō-| noun the action of delaying or postponing something: your first tip is to avoid procrastination. Who would have thought that after decades of struggle with procrastination, the dictionary, of all places, would hold the solution. Avoid procrastination. While we’re here, let’s make sure obese people avoid overeating, depressed people avoid apathy, and someone please tell beached whales that they should avoid being out of the ocean. No, “avoid procrastination” is only good advice for fake procrastinators—those people that are like, “I totally go on Facebook a few times every day at work—I’m such a procrastinator!” The thing that neither the dictionary nor fake procrastinators understand is that for a real procrastinator, procrastination isn’t optional—it’s something they don’t know how to not do. Pretty normal, right? Notice anything different?
Blame My Brain | Nicola Morgan The revised edition of Blame My Brain – The Amazing Teenage Brain Revealed - first published in 2005 and updated in 2007 and 2013. Signed copies available from my online shop, unsigned copies from all good shops, and the ebook from wherever you normally buy ebooks! BLAME MY BRAIN was shortlisted for the Aventis prize for science-writing, is internationally acclaimed, and has been reprinted many times and translated into other languages. It is highly unusual (possibly unique) in being written specifically for teenagers to understand their own brains. “Nicola Morgan has that rare gift of being able to communicate science and make it fun. “I want to say how much I enjoyed the book. “..really good and it taught me a lot about my brain.” “…and me a lot about my son!” I do many events for teenagers and for adults who wish to understand about teenage behaviour and be reassured about it. Scientists used to think that when we are born we have all the brain cells (neurons) we’ll ever have. “….
