“…Better arousal management might also be indicated for not losing appropriate activation levels essential to sport performance (Pelka et al, 2016). Additionally, improved sleep and arousal management along with reduced pain scores and muscle tension, other outcomes of YN, would constitute a virtuous cycle (Sutar et al, 2016), which could lower the possible "threats" of training and competitions on the nervous system. Further, a YN session could replace a traditional nap, stimulating even more vivid and clearer experiences than those that occur in the traditional nap modality, and in light of reduced muscle tension, it can lead to lucid dreaming (see, for e.g., Cebolla and Cheron, 2019).…”
