Sleep researcher, writer and international speaker Greg Potter, PhD is with us once again to continue our conversation about improving your sleep. In my last interview with Greg, we discussed practical steps to take when sleep eludes you, as well as preventing sleep problems in the first place. We've circled back around today to take a closer look at some of the most promising interventions for insomnia as well as special considerations for athletes with regard to sleep.
In this interview, Greg describes Sleep Restriction Therapy and Intensive Sleep Retraining in detail, two approaches to fixing insomnia that sound counterintuitive at first but which can pay off quickly with more restful sleep. Greg talks about mindfulness and meditation, sharing tips for using these practices to reduce insomnia and overall stress. We also discuss sleep considerations specific to athletes, including sleep timing, training load, and travel.
