Sleep and Teenagers: Why Teens Need More Sleep Than Adults

Sleep and Teenagers: Why Teens Need More Sleep Than Adults

As children grow and move to the teenage level, they become a significant stage of their growth and development. Therefore, at this stage, they need more sleep than adults. The average teen needs about eight to nine hours of sleep each night to feel attentive and refreshed. Many factors keep teens from getting enough sleep, and one of the reasons is – early schooling.

Wendy Troxel studies and specialises in behavioural treatments for insomnia and other sleep-related disorders. She believes that teens don’t get enough sleep, and it’s not because of Snapchat, social lives or hormones. It’s because of public policy. Drawing from her experience as a sleep researcher, clinician and mother of a teenager, Troxel confers how early school start times withdraw teenagers from sleep during the time of their lives when they need it most.

However, this question reminds me of a year old TEDx video of Dan Ariely, who shared his hospital experience when he was severely burnt and talked about the concept of ‘Predictable Irrationality’.

  1. Why Kids Lie, and why it’s difficult to detect their lies
    By Ahmad Amirali

‘Sir, I will not come to school because I am not feeling well’, ‘Sir, my monthly evaluations are going to start so I will not come in today’s class’, ‘Sir, my aunt, passed away, I will not come today’. These are the messages which I normally received by an absentee. Although, I eventually find out that all these were excuses (lies) when the absent students’ deceased aunt called me to inform about her nephew’s (my student) cello classes. The cello sessions were the reason behind his skipping my classes but why he lied about it? Instead, he can share the real reason and we might sort out the middle way. What makes him think that I would rather lie to my sir instead of being truthful. Continue reading “Why Kids Lie, and Why It’s Difficult to Detect their Lies”
