Matt returns with  Dr. Craig Kanapari to discuss sleep in teens and how biological and hormonal changes occur at a young age, usually around 11-13. The most clear determinant of sleep duration in a teen is wake time, and enforcing a wake time inappropriate to the teen's natural sleep period can lead to insomnia-like symptoms and create conflict. The single greatest threat to a teen's sleep schedule is early high school start times. California recently signed a law to address this, and other states are beginning to follow suit. They also discuss teenage sleep deprivation and the issues it leads to. They also explore the concept of  social jet lag as well as how teens often have their own devices and are allowed to keep their phones in their rooms. The conversation continues with the effects of chronic sleep deprivation on teenagers, including on academic performance and psychological effects such as depression and anxiety, as well as the health and safety implications, such as increased risk of car accidents. Lastly, they recount the relationship between kids and ADHD, sleep deprivation, and medication. Specifically how teens not getting enough sleep can masquerade as ADHD, how stimulants used to treat ADHD can affect nighttime sleep, and the issue of hypersomnia. It suggests that parents look out for their children's sleep duration and snoring, and if their child is struggling, not to forget about sleep as it is important for their health and wellbeing.
